Prep Time 20 minutes
Cook Time 50 minutes
Total Time 1 hour 10 minutes
Servings 5 cups



  • 1 medium yellow onion, peeled
  • 1 small Russet potato, scrubbed
  • 4 cups cauliflower florets (from about ½ medium head of cauliflower)
  • 4 cloves of garlic, peeled
  • 1 tablespoon avocado oil
  • 2 teaspoons poultry seasoning
  • sea salt and ground black pepper
  • 2 tablespoons mellow/light miso
  • cup raw cashews (soaked for at least 2 hours and drained)
  • 2 teaspoons balsamic vinegar
  • 3-4 drops liquid smoke
  • 3 ½ cups vegetable stock (preferably homemade)


  • Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
  • Cut the onion into 8 wedges and transfer to the baking sheet. Cut the potato into 1-inch pieces and transfer to the baking sheet as well. Then, add the cauliflower, garlic cloves, avocado oil, poultry seasoning, and lots of salt and pepper to the baking sheet. Toss the vegetables thoroughly to coat in the seasoning. Separating the wedges of onion to expose more edges.
  • Slide the vegetables into the oven and roast for 50 minutes (yes, 50 minutes), flipping and stirring them at the halfway point. You want deep caramelization and browning on all the edges.
  • Once the vegetables are sufficiently roasted and slightly cooled, transfer them to an upright, high speed blender. To the blender, add the miso, drained cashews, balsamic vinegar, liquid smoke, and vegetable stock. Slowly bring the speed of the blender up to high and blend until your gravy is completely smooth. If you’re finding it to be too thick, add more vegetable stock until you achieve a pourable, but still thick, consistency.
  • Check the gravy for seasoning at this point. If it needs more salt, vinegar, pepper, miso, or even more poultry seasoning to suit your taste, adjust accordingly.
  • Transfer the sheet pan gravy to a medium saucepan and bring it to a light boil. Serve the hot gravy with mashed potatoes and all of your other favourite holiday foods!


  • It’s important to get as much caramelization as you can on the vegetables when they’re roasting. It’s what takes this recipe from soup-esque right on over to bonafide gravy vibes.
  • The liquid smoke IS optional, but I’d really recommend seeking it out for this recipe and a bunch of other great things that you can add it to. I can’t make a pot of beans without it now :)
  • I used a rich homemade vegetable stock for this and I’d recommend that you do the same. My go-to recipe can be found here.
  • If mushroom gravy is your thing, I have a great recipe here.
