In this baked stew (I’m trying really hard not to call it a casserole), the lentils and vegetables bake low and slow in a savory balsamic broth until everything is tender and well-married. The crispy rosemary potatoes on top remind me of a pot pie without the pastry, which is infinitely easier. As one reader put it: “It has been our Thanksgiving entree these last couple of years and goes so well with all of the traditional sides.” Perfect for holiday entertaining, and just as welcome on a slow Sunday. Serve it with my no-knead whole wheat bread for catching all the gorgeous broth.
The dish is meaty and filling but light and balanced too. Comfortingly beige with a feel-good edge! The balsamic brings a dark, slightly sweet acidity that gives the broth real depth without tasting overly vinegar-forward. It plays nice with the rosemary and the earthiness of the lentils.
I use green or brown lentils here specifically. I like how big they are and appreciate that they hold their shape through the long bake. They don’t go mushy the way red or yellow lentils would. The mushrooms add a meaty quality that makes the stew a bit more satisfying as a main course.
The potato topping is the most exciting part. Thin slices shingled on top, brushed with olive oil and rosemary, and baked until crispy at the edges. I like to slice the potatoes and trim into “domino” sized rectangles. It is a small extra step that makes the whole dish feel special.
Baked Balsamic Lentil Stew with Mushrooms & Rosemary Potatoes
Ingredients
- 2 tablespoons olive oil, divided (plus extra)
- 1 ⅓ lbs cremini mushrooms, stemmed and sliced
- salt and ground pepper, to taste
- 1 medium yellow onion, finely chopped
- 1 medium carrot, finely chopped
- 1 stalk celery, finely chopped
- 2 leeks, chopped (white & light green parts only)
- 1 sprig fresh rosemary, minced (plus extra)
- 4 cloves garlic, minced
- 1 cup green or brown lentils, rinsed
- 1 tablespoon balsamic vinegar
- 1 tablespoon Tamari soy sauce
- 4 cups vegetable stock, divided
- 2 large yukon gold potatoes
Notes
- I trimmed the potatoes into rectangles so that I could have a domino effect (hehe), but the natural potato rounds are obviously just as great and a little lower maintenance.
Instructions
- Preheat the oven to 425°F. Set a 9x13x2 baking dish on the counter.
- Heat 1 tablespoon of the olive oil in a large, heavy soup pot over medium heat. Add the sliced mushrooms to the pot and let them sit for a full minute. Season the mushrooms with pepper and stir. Let the mushrooms sit another minute or so. Season the mushrooms with salt and stir continuously until the mushrooms are soft and moist. Transfer cooked mushrooms to a plate or bowl and set aside.
- Pour the remaining olive oil into the pot. Add the onions, carrots, celery, and leeks to the pot and stir. Cook and stir until the onions are quite soft, about 5 minutes. Add the rosemary and garlic to the pot and cook for 30 seconds, or until fragrant. Add the lentils to the pot and stir to coat in the oil/vegetables. Pour the balsamic vinegar and tamari into the pot and scrape up any brown bits that have accumulated.
- Pour 3 cups of the vegetable stock into the pot. Bring the lentils to a boil and then lower the heat to a simmer. Cover the pot and cook until lentils are just tender and there is only a tiny slick of liquid left in the pot, about 18 minutes. Season the lentils with salt and pepper.
- Turn the heat off and stir in the cooked mushrooms and remaining cup of vegetable stock. Transfer the stew to the 9x13x2 baking dish. Pat the stew down into the dish. There should be just enough liquid to keep things ever-so-slightly fluid—like a thick, but still broth-y, stew.
- Trim the sides off of the potatoes so that you have 2 relatively even rectangular prisms of potato. Then, using a mandolin, slice the potatoes into ⅛ inch-thick slices. Lay out the slices and blot them dry with paper towel.
- Layer the potato slices on top of the lentil stew, covering the entire surface. Drizzle the top of the potatoes with olive oil, season with salt and pepper, and scatter some extra rosemary leaves.
- Slide the potato-topped stew into the oven and roast until the potatoes are very lightly browned on the edges and tender, about 35-40 minutes. Then, set the oven to broil and let the potatoes brown even further for about a minute. Serve the stew hot with sections of the potatoes on top.
Tonight was the second time I made this meal. What a great recipe! Your page is on my go to list if for no other reason than this dish.
Your recipes are the most innovative and delicious I’ve ever found on the internet. This recipe is mine and my boyfriend’s favorite, it’s so savory, we just want to drink the broth. I’ve been using a light apple balsamic instead because that’s just what I have on hand and it’s wonderfullly sweet as a result.
Made it, loved it. So easy and I think adaptable with other spice combos, or sweet potato instead of the yukon golds. I’m not a very good cook so being able to make this was a great confidence booster! I didn’t even use a mandolin and the top turned out nicely. I served with a dollop of Greek style yogurt (the kind made with goats milk gives extra flavor). Thank you for the recipe.
Hello Laura! I wasn’t familiar with your blog—I found this recipe on Pinterest and made it tonight and I had to come on here to tell you that it is FABULOUS. So rich (yet not heavy) and flavorful and sooooooo satisfying. I’ve already sent it to some other friends—both vegetarian and not—because I think its absolutely delicious and also beautiful. Just wanted to let you know! Thank you :)
Just made this and it is FANTASTIC. I didn’t have leeks so I just omitted them. Used french green lentils. I also don’t have a mandoline so I just sliced the potatoes thinly and they cooked just fine. Will definitely make again!
Prepared this recipe – but the 4 cups of veggie broth was way too much. In the initial pan cook, I had to discard at least 1 cup of broth. And, I cooked it for 4x the amt. of time. Lentils were soft.
I’ve made this a couple times and I’m making it again tonight! Love this recipe so much. Definitely a go to one for me. I just need a mandolin that can slice this thin.
I made this in order to hit my reset button! I normally skip right past the spiel before a recipe when I’m online, but I’m glad I didn’t in this case. Without being corny, you added another dimension to my cooking experience because I really related to what you wrote. Thank you graciously ❤️
It’s actually rather nice to hear that there is a USA/ Canada Pulses council (& they’re supporting you) when you hear so much about egg/ milk/ meat industry/ board pushing their cruelty-filled products by paying chefs or government etc to encourage people to eat aforementioned products. plant protein for the win
Fab – whole family loved it and only one vegetarian here!
Would this be freezable Laura?
I think you could get away with freezing it if it was fully cooked, but even then… I find mushrooms don’t always fare very well after being frozen. I have’t tried freezing this one yet, so if you have success please let me know.

Hi Laura! Can I use black chickpeas instead of lentils? Also can I use sweet potato instead of russet?
Hi Karishma,
The black chickpeas, if you’re using from their dry state, will take much longer to cook than the lentils. They’ll also require more liquid. This is a situation where Googling might offer better advice than what I can give because I’ve only made this recipe with the lentils.
If your black chickpeas are cooked though, you would need double the amount that I specify of lentils (so 2-2 1/4 cups total of cooked black chickpeas). You wouldn’t need as much vegetable stock if you’re using cooked beans because they wouldn’t be taking on any liquid. Just use enough to keep the whole mixture moist and slightly fluid.
And yes, you can use sweet potatoes for the topping, but they won’t crisp up like the russets. I would recommend slicing them as thin as you can just because they’re definitely wetter/more dense than regular potatoes.
-LW
Thank you Laura. I’ll let you know how the black chickpeas turn out. And yes, I’m going to boil them before hand. Excited to make this recipe!
Can’t wait to try this – I have recently discovered your blog (and I just got your cookbook! Swoon!) Does the baking sheet need to be oiled before the lentils are spread around? Thanks!
Thank you so much! Yes, I’d recommend oiling the dish ahead of time ;)

Holy moly was this ever delicious! Thank you for such a simple and delicious recipe. I added 2x the balsamic and used de puy lentils. Such a delicious, warming meal in this western cold snap we’ve been having!
Late to the party, but oh my goodness this looks amazing. I can taste those potatoes.
Beautiful blog!
We LOVE lentils! They’re a staple in my frugal and healthy kitchen. They’re cheap and versatile! Your food photography is absolutely amazing, I must say. What a great website! Kelli Brink
Simply one of the best vegan recipes I have ever, ever made. This was off the charts delicious. My carnivore fiancée had 3rd helpings AND took some for lunch much the next day.
I served this to a whole house full of meat-loving friends and family and it went over spectacularly. I can always count on your recipes to do so!
I made this last night and it was delicious! The perfect blend of flavors + the potatoes on top were delicious.
I happen to have some mushrooms and lentils right now, and never thought of combining the two. Sounds awesome. I also love combiningn feta cheese with lentils or mushrooms, so might throw some in too! Thanks!
I’m so into this coziness right now! Also your potato dominos are adorable/beautiful. I have a similar strategy (making a super healthy dish to interrupt my less-than-amazing stressy choices) and it really does help turn things around. Hang in there these last few weeks of 2016! xo
This looks SO delicious – just perfect for a cold winter’s night!
Made this today! It was really good and filling, just a little bit time consuming to chop all the ingredients, but it was worth it!
Thanks for the recipe :)
Very delicious recipe!! loved it.
This was so delicious! When I saw the picture I thought it was going to be time consuming to make…it really wasn’t! I had friends over for dinner and it was a hit :)
I can’t get over how beautiful and cozy this is, Laura! I could get lost in that first photo, and this crispy thin potato lid. Just perfect.
This recipe is amazing! It will definitely be going into my regular rotation. I used potato shaped slices out of laziness but it still looks pretty! I would double it to serve 6-8 though, I ate the whole thing myself in 4 servings!!
Hi Laura,
This looks delicious!
Do you think I could use red lentils in lieu of the green ones? I have some sitting pretty in my pantry, but I don’t want to make the substitution if that will ruin the dish!
Hi Jessy!
The red split lentils will definitely break down completely in this recipe–making for a creamier and runnier texture. The green/brown ones retain their texture. You could try it if you want because the cook time would be the same, but I don’t think I would recommend it.

Can I be wrapped in a cozy, salty potato blanket??!? But seriously, Laura, between this baked lentil stew, Jessie’s savory cobbler, and Lindsey’s vegan alfredo, I feel like I’ve hit the plant-based comfort food goldmine! Your photos are absolutely sunning and have no sense of dullness whatsoever. They perfectly convey the idea of comfort and warmth during this chilly season. This dish really does sound delicious!
This is an awesome way of making an otherwise “dull” stew gorgeous. I made the stew with the addition of deer meat and it is in the oven now smelling wonderful! Thank you for the inspiration! xo Kristi
I saw it on your instagram and had this feeling that I’m going to make it. I love the recipe.
Hi Laura! Looks delicious! Would you tell me what kind of mandoline you are using to cut the potatoes in such thin slices?
Greetings from Austria :)
Lara
Hi Lara! I have this one from Benriner, and the blade has never dulled in all the years I’ve used it: http://www.benriner.co.jp/benriner_en/products/products01.html

Thanks Laura!
Hi Laura. Do you think I could make this ahead of time and bring it to a family get together that is about a one hour drive away? I was thinking I would cook it partially, and then finish off the cooking and broiling stage when I get there? Do you think that would work?
I think your strategy of partially cooking it and the broiling at your destination might be the best way to do it! I would cook this right up to the broiling stage, wrap it up, slowly warm it back up at your destination, and then broil it for a minute or so. Let me know how it goes!

I made this dish for dinner last night. It was delicious and by far the best lentil dish I have ever made! I can’t wait to make it again for my family during the holidays.
That is wonderful to hear, Chris! Appreciate it so much.

This stew looks so delicious and those paper thin potatoes – wow! No chance my mandolin can do that – looks like gotta invest in a new one!
this is such a creative idea (as usual) and you’ve somehow managed to make it look gorgeous. also your kitchen is amazing!
Stellar blog. I wish I was yourger and had grown up with all the tech savvy ways of expressing ourselves. You are brilliant and a reminder to us, older grumps, that better times are yet to come. You are an all time classic food writer and your documented sensitive thoughts on cooking and eating shall survive many decades. Kudos to you and your progenitors . They should be sooo proud. Much love and Peace from upstate NY
Wow this looks absolutely delicious and the perfect dish for Christmas! I can’t wait to try this recipe out
Definitely sounding familiar to me ;) I think I’ve had waffles for breakfast 3 days in a row (but they are made with chickpea and brown rice flour so that’s healthy riiiight)! Studying/exams/work are all things that make my eating habits change a little. Loving this stew <3
Is there any way this recipe could be adapted for a crockpot? I’m a med student with final exams coming up, and this looks incredible, but I’d love to be able to have it cook while I’m away!
The potatoes are GORGEOUS- glad I stumbled upon this- looking for more ways to use lentils. Thanks for sharing!
What a creative idea! This looks delicious and such a cozy dish for winter :) Can’t wait to try!
I love the idea of domino-potatoes :D
Brown food may not be as eye catching as brightly colored food, but it’s still elegant and beautiful in its own ways. Thank you for this recipe- I’m always looking for new ways to eat lentils, and these lentils are making me hungry.
This recipe is gorgeous, as always, but I really came here to say that your kitchen = #goals. Ryan and I are trying to figure out how we want our new kitchen to look, and I legit pulled up your Instagram feed to show him your countertops + subway tile. Is that weird? Maybe? #YOLO
No, I don’t think that is weird. :) I did a screenshot on my phone of her kitchen in Instagram so I could zoom in on it. Everything is so beautiful and I looove the copper pots. It makes me happy when I come to it while looking thru my pics!
This looks fantastic! I’m going to try it with sweet potatoes -I usually substitute them for other starchy potatoes because they are very healthy and flavorful. You could use the white variety of sweet potatoes, which are available this time of year, to keep the color consistent if family won’t eat the orange ones! :). Thanks for the recipe.
Love this tip! Thanks Sarah :)

This recipes looks amazing. You are a genius :)
Love the creative twist of a lentil shepherd’s pie! I’m going to try this but instead of potato prisms; I think I’ll cut the potato into rounds to add a pretty scallop touch to the dish :)
I can’t read your blog today. :( The Eddie Bauer and le creuset ads keep covering up your post and I can’t even move them at all on my iPad!
Sonia, I’m so sorry about this. I’ll contact my ad provider with these details right away, and hopefully this won’t happen again. I appreciate you letting me know.
-L
Welcome. :) it does seem good now. And not that I don’t love le creuset, but I’d rather read your blog.
Another great way to make lentils…can’t wait to try that blanket on top of it. Happy feasting.
