This crazy delicious, hearty vegan mushroom stew rivals any non-vegan version. Served with creamy roasted garlic and chive mashed potatoes (and red wine, of course), it's vegetarian comfort food at its finest!

Today is officially the last day of winter (YAY). We're bidding it a not-so-fond farewell with the ultimate comfort food: vegan stew with mashed potatoes!

It doesn't have to be cold outside to enjoy this cozy stew with mashed potatoes. It does, however, always make me want to curl up by the fireplace with a book, and/or travel to Ireland immediately.

In fact, we were inspired to develop this recipe after last year's family trip to Ireland. While we were able to find plenty of gluten free meals, the Irish aren't too big on vegan food (yet). Most of their meals revolve around meat, and pretty much every single restaurant has beef stew on the menu.

After watching the rest of the family happily indulge in stew + mashed potatoes one too many times, we decided to make our own version at home. Mushrooms are the perfect vegan alternative to beef. They soak up a ton of flavor, and when stewed for a few hours, they take on a tender, meaty texture.

How to make hearty vegan mushroom stew on your stovetop

To start, make sure you carve out enough time for the stew to simmer. We recommend at least 1 ½ hours of simmering time, or even up to 3 hours.

The good news is, once you prep everything and add it to the pot, you can clean all of the dishes and then let it do its thing without any interference. Although stew can be time consuming, it's pretty low-effort. Plus, time allows the flavors to develop, so it tastes like you've been slaving over the stovetop all afternoon!

What kind of mushrooms do I use in vegan stew?

White button mushrooms, cremini mushrooms and portobellos are all good choices for this stew. In fact, they're all technically the same variety of mushroom!

White button mushrooms are the youngest, softest variety. Cremini mushrooms are the "middle child"; much darker in color, a bit sturdier and similar in flavor to button mushrooms. Portobello mushrooms are the oldest variety, which you can obviously tell by their much larger size and more developed flavor.

I personally prefer cremini mushrooms in this stew. They're small enough that they don't need to be sliced, and they're sturdy enough to hold up to multiple hours in a pot. If you do use portobellos, be sure to roughly chop them before adding to the stew.

How to add flavor to your stew base

The key ingredient: red wine! And lots of it. Red wine adds incredible depth of rich flavor to this vegan mushroom stew. Not to mention, it makes your kitchen smell amazing.

Opt for a Pinot Noir, Cabernet, Merlot, or even a red wine blend. Don't skimp on quality! Even though the wine cooks out quite a bit, a better wine makes a better stew. Plus, you only need a cup to a cup and a half, so you can drink the rest with dinner.

Simmer, simmer, simmer!

After you sauté the onions, garlic and carrots for a few minutes, you can essentially dump everything else into the pot and start simmering.

To make sure the stew gets nice and thick (you don't want a soupy texture), you'll need to also add in some gluten free (or regular) flour. Don't just dump it in with everything. Heat up another small saucepan and turn it to medium-low. Add some olive oil and the flour, whisk well, then add broth and continue whisking until smooth.

As long as the mixture is smooth, it's ready to add to the stew. Don't worry if the stew doesn't look thick immediately after you add the flour mixture. After about an hour of simmering, it will start to thicken. By the time you serve, it should be the perfect texture!

Serve with roasted garlic mashed potatoes

As much as I love the mushroom stew, I have to admit that the potatoes are my favorite part.

We added a few cloves of roasted garlic, fresh chives, and lots of vegan butter, so needless to say, they're AMAZING. It's always dangerous for me to make mashed potatoes - I could eat the whole batch without even noticing!

About 1 hour before your stew is finished, turn on the oven and prep your roasted garlic. Here's a quick tutorial on how to make roasted garlic. It makes all the difference in these vegan mashed potatoes and it's well worth the effort!

  1. Start with an entire head of garlic. Turn on its side and slice the top off, just enough to expose the cloves.
  2. Drizzle with EVOO, salt and pepper (optional), wrap in aluminum foil and roast at 400F for 30-35 minutes, until golden brown and tender.

Voilà! Perfectly roasted garlic in two steps.

When garlic is roasted, it brings out a much sweeter flavor and removes the harsh bite of fresh garlic. I love garlic as much as the next person, but too much raw garlic doesn't always agree with my stomach (or breath!).

We try to keep some roasted garlic on hand at all times. It's particularly delicious in homemade hummus or this spicy white bean dip!

Instructions

Stew: 

  1. Heat 2 tablespoon oil in a large pot over medium heat. 
  2. Add onions and sauté for 7-8 minutes, stirring frequently. Add garlic and cook another 2-3 minutes. 
  3. While onions are cooking, add remaining 3 tablespoon olive oil to a smaller pot over medium-low heat. Add flour and whisk until no lumps remain. Slowly whisk in 2 cups of vegetable broth and whisk until smooth. 
  4. Once onions and garlic are softened, add carrots, potatoes, mushrooms, green beans, peas, herbs, tomato paste, salt, pepper, and paprika to pot and stir well. Add red wine and let simmer for a minute or two before adding in broth + flour mixture + remaining two cups of broth.

    Are you considering 1 serving like that plate pictured (a fully covered plate)? I'd be making this just for me, so I might need to cut the recipe in half. Can the stew be frozen? Also, can I use broth made from vegan beef bouillon instead of vegetable broth for the stew?

      Hi, yes, I would cut this in half if it's just for one person! Yes, it can be frozen. And definitely, that works for the broth! Hope you enjoy.

    Delicious! My whole family loved this dish. Used ground flax instead of flour to make the gravy. Will definitely make this as a regular family meal!

    Made it for Christmas and it was so good! Only thing I did wrong: it didn't thicken as much. I think I added the broth too fast to the flour mix. Will make sure to go slower next time. And there will be a next time, going to try it in the crockpot, and see how that goes.

    This looks delicious! But my husband is diabetic, so I'm wondering if I could replace the Russet potato with sweet potato? Or mashed cauliflower?
    Or would that ruin the flavor?

      Yes, you could definitely sub with sweet potato or cauliflower!

    Hi, I love this recipe! My girlfriend and I cooked this meal multiple times and it was always absolutely amazing! I like to add a few juniper berries and a bay leaf or two, they both add even more depth of flavor to the stew. The juniper also adds a bit of, I'd say, fruitiness. Anyways thanks so much for this delicious recipe.

    Absolutely phenomenal! This stew is the closest vegetarian recipe I’ve made to a proper stobhach gaelach (Northern Irish stew) and it’s vegan AND gluten-free to boot! The depth of flavour is wonderful!

      That's the best feedback!! I tried to model it off of stew I had in Ireland several years ago before I went vegetarian, so I'm thrilled to hear you enjoyed. Thank you for your comment!

        This came out great!! I was looking for an interesting vegetarian recipe that would include mashed potatoes (which I was craving). The kids said they couldn't believe there wasn't meat inside and loved it, too. I added bay leaf and rosemary to the stew and scallions to the mashed potatoes. Total yum and a comforting dish.

    This is the tastiest vegan dish I've ever eaten! We thoroughly enjoyed it. Plenty left for the next couple of days so I'm happy to read that it freezes. Well worth the effort cutting everything up and the time it took. I actually hate cooking, but this mealmade it all worthwhile. Thank you!
