The reasons you’ll fall for this recipe

Cozy flavor with everyday ingredients

This stew builds deep flavor from simple steps: browned mushrooms, caramelized onions, and toasted spices. Lentils add a natural meatiness and body, while a splash of tomato paste and soy or tamari brings umami. You don’t need specialty items to get a rich result.

Quick to make, easy to love

Cooking time is mainly simmering, which frees you to prep sides or relax. The active steps take about 20–30 minutes. If you keep canned tomatoes, dried lentils, and stock on hand, you can get this on the table on a weeknight.

How to make this Vegan Lentil Mushroom Stew

The method stays simple: build flavor, add liquids, simmer until tender.

Step-by-step cooking instructions

1. Heat oil in a large heavy pot over medium-high heat. Add mushrooms and a pinch of salt. Sauté until they release moisture and start to brown, about 6–8 minutes. Remove mushrooms and set aside.
2. Add a bit more oil if needed. Sauté onion, carrots, and celery until soft, about 5–7 minutes. Stir in garlic and cook 30 seconds.
3. Stir in tomato paste, smoked paprika, and thyme. Cook 1–2 minutes to toast the paste and spices.
4. Add lentils, potatoes, browned mushrooms, soy sauce, and vegetable broth. Bring to a simmer.
5. Reduce heat, cover partially, and simmer gently until lentils and potatoes are tender, 25–35 minutes. Stir occasionally and add extra broth or water if the stew becomes too thick.
6. Taste and season with salt and pepper. Finish with chopped parsley and a drizzle of olive oil if you like.

Tips for texture, timing & tools

• Use green or brown lentils; they hold shape better than red lentils.
• If you prefer a creamier stew, mash a cup of the cooked lentils against the pot wall and stir.
• A heavy-bottomed pot or Dutch oven gives the best browning and even simmering.
• If you have less time, pressure cook for 10–12 minutes (follow your device’s lentil guidelines), adding potatoes later if needed. For slow, savory development, a low simmer for the full time gives the best result.

Storage, reheating, and more

How to store it right

Cool the stew to near room temperature, then transfer to airtight containers. Refrigerate for up to 4–5 days. For longer storage, freeze in portions for up to 3 months. Thaw in the fridge overnight before reheating.

Reheating without losing flavor

Reheat on the stovetop over low heat, adding a splash of water or broth if the stew has thickened. Reheating slowly keeps the texture and prevents overcooking the lentils. You can also warm single portions in the microwave, covered, stirring halfway.

A dish worth making again and again

This stew holds up well as leftovers. Flavors meld and deepen after a day or two, so it often tastes even better the next day. For a fresh finish, add a squeeze of lemon or a handful of fresh herbs when serving.

You can also try a sweeter take that pairs well with mashed sides in recipes such as apple cider stew over mashed potatoes for holiday-style meals.

FAQs

Can I use canned lentils instead of dried?

Yes. If you use canned lentils, add them near the end of cooking just to heat through, since they are already tender. Reduce the initial simmer time accordingly.

What if I only have button mushrooms or shiitake?

Both work well. Button or cremini provide a mild, meaty base. Shiitake bring woodier notes—either is fine. Slice mushrooms evenly so they cook uniformly.

Can I make this in a slow cooker?

Yes. Brown the mushrooms and sauté the aromatics first for best flavor, then transfer everything to the slow cooker. Cook on low 6–7 hours or high 3–4 hours, adding potatoes later if you want firmer pieces.

Is this suitable for meal prep?

Absolutely. Portion into meal-size containers and refrigerate or freeze. This stew reheats nicely and makes an easy lunch or dinner.
