This Portobello Pot Roast recipe is the ultimate one-pot family meal. With meaty portobello mushrooms, chunky vegetables, red wine and herbs, it's rich, flavourful and hearty.

How to make Portobello Pot Roast

A traditional Pot Roast is made by searing the meat, then placing it in a pot with the vegetables, broth, sometimes some wine and herbs. It's then all roasted together really slowly in the oven.

This Vegan Pot Roast is made in much the same way, by searing the portobello mushrooms then cooking them with the vegetables and broth in the oven.

Remember when you put it all together, that not much evaporation happens in the oven because it has a lid on it,  so don't add too much broth at first. Check it as it's cooking and add a little more if you think it needs it. You can always add more but you can't take it away.

I like to use the broth sparingly when I make this recipe so that the gravy is really thick, dark, rich and flavourful like in the photos, but you can add more broth (like in my video), so it is much thinner if you prefer. It's almost like a stew then.

How to serve

This Portobello Pot Roast smells amazing and is so rich and delicious.

Serve it with some extra oil-free crispy roasted potatoes or my vegan mashed potatoes and some crusty bread to mop up that tasty gravy.

Also on the side, some steamed vegetables, roasted red cabbage, a little horseradish sauce and a big glass of red wine. The horseradish complements it perfectly.... as does the wine - hic ...

Got an Instant Pot?

If you have an Instant Pot, I have created a Vegan Portobello Instant Pot Pot Roast which you will love!

Here it is:

Possible variations

This recipe has become a staple for us.  I do however add a little more red wine to the sauce and a bit less stock. A few dried and rehydrated porcini mushrooms to intensify the flavour a little are amazing too. Some other ideas:

• Cook it, let it cool and use it as a pie filling. Make it as directed so the gravy is pretty thick. Then make a pastry crust and fill it with the pot roast to make a pie. Divine is the word!
• Cook in a slow cooker - Directions are in the recipe

TOTAL TIME: 1 hour 30 minutes

Servings: 4 servings

Ingredients

  

1x2x3x

• ▢ 1/2 cup | 120mls red or white wine , I think red works best
• ▢ 4 large portobello mushrooms sliced into 3/4-inch pieces
• ▢ 1 large onion sliced
• ▢ 2 cloves garlic pressed
• ▢ 3 tablespoons flour if sensitive to gluten use gluten-free flour
• ▢ 1 teaspoon rubbed sage
• ▢ 1 teaspoon dried basil
• ▢ 3 cups | 720mls vegetable broth divided. If you use all the broth it will end up with thin gravy like in my video. I personally prefer to use less and have a thicker gravy. Usually about 500 mls total.
• ▢ 4 large potatoes quartered
• ▢ 4 large carrots cut into 3-inch pieces
• ▢ Salt and freshly ground black pepper or lemon pepper to taste
• ▢ 2 teaspoons vegan Worcestershire sauce , or 1 tablespoon of soy sauce or tamari
• ▢ 4 sprigs fresh thyme
• ▢ 1 sprig fresh rosemary

INSTRUCTIONS

 

• ▢
  Preheat the oven to 350 degrees F (for slow cooker instructions see recipe notes)
• ▢
  In a large saucepan (or a large stovetop to oven like a Dutch Oven , heat 1/4 cup of the wine and add the portobello mushroom slices. Allow them to cook through and brown a bit—you’ll need to keep moving them around and turning them—and then remove from the pan and set aside.
• ▢
  Add the remaining 1/4 cup wine to the pan and add the onion and garlic. Caramelize the onions by stirring them until they wilt and begin to brown. Remove the onions from the pan and set aside.
• ▢
  Mix the flour, sage, and basil together in a small bowl. Stir in 1/4 cup of the broth to create a paste, and pour the mixture into the same pan you used for the mushrooms and onions. While stirring constantly over medium heat, very slowly add the rest of the broth so that you create a gravy or sauce. 
• ▢
  When the mixture just starts to boil, turn the heat off and add any additional seasonings you prefer, such dried herbs and black pepper. 
• ▢
  Add the potatoes, carrots, salt and pepper, and Worcestershire sauce to the gravy mixture. If more liquid is needed to keep the vegetables from drying out, add more broth.
• ▢
  Add the mushrooms and onions to the mixture and ladle into a large ceramic or glass pot or casserole dish with a lid, layering in the sprigs of rosemary and thyme. Place the lid on and put into the oven and bake for 1 hour. Remove from the oven and serve hot.

NOTES

For more flavour, replace some of the broth with extra wine and throw in a handful of dried porcini mushrooms before it goes in the oven.

If you would like to cook this Portobello Pot Roast in a slow cooker then prepare as directed until the gravy is made, then tip it into the slow cooker and add the rest of the vegetables and the seasonings. Sit well and  cook on low for around 4 hours or until the potatoes are tender. Add a little more liquid if it looks like it might dry out towards the end. You could use broth or some red wine.
