This Vegan Instant Pot Portobello Pot Roast recipe my friends, is the bees knees of Vegan Pot Roasts. It does not get any better. It seriously blew me away when I first made it. The flavour is incredible. That gravy ....
We're talking meaty portobello mushroom slices, soft, melting potatoes, sweet carrots and rich, super flavourful, thick gravy. We're talking ultra deliciousness with bells on.
And don't worry, the mushrooms are not cooked in the Instant Pot the whole time, so they don't end up like little wrinkled, slimy slivers. They get sautéed up until golden in the beginning, then removed until the end so they retain their lovely meaty texture. Just look at 'em close up ...
There is something incredible about large chunks of potatoes cooked in gravy in the Instant Pot. They become, soft, sweet and delicious and I just can't get enough of them.

How To Make Vegan Instant Pot Portobello Pot Roast
Aside from it's amazing flavour, the great thing about this recipe is it's convenience. Making it in the Instant Pot is so easy and you literally have one pot to wash up after. Here's how you do it:
- Saute those 'shrooms, right there in the Instant Pot then scoop them out and save them for later.
- Sauté the onions and garlic.
- Add everything else except the flour and cooked mushrooms and cook on high pressure.
- Stir in the flour slurry and the mushrooms and simmer until thickened and then serve.
It doesn't really need much in the way of accompaniments, apart that is, from a big glass of wine and some good bread to mop up that delicious gravy. A big hunk of sourdough or No Knead Focaccia Bread makes the perfect gravy mopper-upper!
Cook on the stove top instead. Just follow the instructions as above, but use a large soup pan and simmer on medium low until the potatoes are soft when you poke them with a fork.
Or, cook it in the oven. Follow all of the same instructions above, but sauté in a pan on the stove top, put everything (except the sautéed mushrooms) into a casserole, cover and bake on 350°f for about 1½-2 hours or until the potatoes are soft. Then thicken the gravy as instructed, add the mushrooms back and let it thicken in the oven for another 10 minutes before serving.

- 4 large carrots , peeled and cut into 1 inch chunks
- 1½ cups (360 mls) red wine
- ¼ cup (60 mls) soy sauce or Tamari (or gluten-free tamari/soy sauce, or coconut aminos).
- 2 cups (480 mls) good quality vegetable or mushroom broth
- 1 teaspoon salt , plus more to taste
- ½ teaspoon black pepper , plus more to taste
- 1 tablespoon sugar

INSTANT POT INSTRUCTIONS (My Instant Pot is a 6 quart. If yours is a different size you will need to scale the recipe up or down accordingly).
- Set the Instant Pot to sauté and add 1 tablespoon of the olive oil (or use a few tablespoons of water instead if you prefer cooking oil free). Add the mushroom slices and cook until they have a good golden colour all over. Then remove to a plate or a bowl and set aside.
- Add the remaining oil (or more water), and sauté the onions until golden. It's important to get a good colour on them because that's what adds lots of flavour. Once golden, turn off the Instant Pot and immediately add the garlic, stirring it in and letting it cook in the residual heat.
- Add the potatoes, carrots, wine, soy sauce, broth, sugar and seasonings then give it all a good stir. Really scrape into the bottom to get the brown mushroomy residue off and into the gravy for extra flavour.
- Place the fresh herbs on top, place the lid on the Instant Pot and seal it, then set it to Manual (Pressure Cook on newer models), High Pressure for 15 mins.
- Once it's done, leave the pressure to release naturally. While waiting make a slurry with the flour. Add water to it gradually to make a lump free paste then add a little more, stirring constantly until it's pourable like cream.
- Once the pressure has released turn off the Instant Pot, remove the lid, scoop out the herbs and discard. Turn the Instant Pot to "sauté" and pour in the slurry, stirring immediately to incorporate. Then add the mushrooms back in and stir gently again. The potatoes will be really soft and might break a little but that's ok. They taste at their best when soft like that in this recipe. Give it a couple of minutes for the gravy to thicken a bit and the mushrooms to warm through then serve.
I made this tonight. It’s amazing! So tasty. I’m already looking forward to the leftovers for tomorrow.
Melanie McDonald says
So pleased you enjoyed it! It makes the best leftovers!
I made this many times and always loved it! Warming and comforting, and so easy to make, such a great recipe.
If I were to make this the night before an office luncheon, would it reheat well in the Instant Pot? TIA!
Melanie McDonald says
It does reheat well, but I've never tried reheating this or anything else in my Instant Pot. My first thought is the potatoes and mushrooms might end up a little overcooked if you pressure cook it again, and if yours is anything like mine everything boils and bubbles like mad on saute. Maybe use the slow cooker function to reheat it if time allows rather than pressure cook or saute?
So so so yummy!!! Flavors are spot on!
