The Rich History of Vegan Lentil Stew With Creamy Mashed Potatoes

What Ingredients Do You Need for Vegan Lentil Stew with Creamy Mashed Potatoes?
Green or brown lentils are perfect here because they hold their shape during a long simmer while getting buttery-soft inside.
The mirepoix (onions, carrots, celery) builds a solid flavor foundation.
Tomato paste, soy sauce, and Dijon mustard team up to create a deep umami profile that mimics long-simmered beef stew without the meat.
Substitutions & Variation Ideas
Substitutions: Soy Sauce: Swap with liquid aminos or tamari to make the dish certified gluten-free. Potatoes: Cauliflower mash or sweet potato mash makes an excellent low-carb or sweeter alternative to regular mashed potatoes. Olive Oil: You can use vegetable broth to sauté the vegetables if you prefer avoiding oil.
Variations: Spicy Lentil Stew: Add a pinch of red pepper flakes or a dash of hot sauce if you like a little heat in your comfort food. Mushroom Boost: Sauté some chopped cremini mushrooms along with the mirepoix for an even deeper, earthier umami flavor.
How Do You Make Vegan Lentil Stew with Creamy Mashed Potatoes?
This recipe takes 15 minutes of prep and 65 minutes of cooking. Follow these 7 simple steps:
How to Make Vegan Lentil Stew with Creamy Mashed Potatoes
- Start the Lentil Stew: Heat olive oil in a large pot over medium heat. Add diced onion and sauté for 3–4 minutes until softened. Add garlic, carrots, and celery. Cook another 5–6 minutes until slightly softened.
- Build Flavor: Stir in tomato paste, Dijon mustard, and soy sauce. Cook for 1–2 minutes to deepen flavor.
- Simmer the Stew: Add lentils, vegetable broth (start with 4 cups), thyme, rosemary, bay leaf, and black pepper. Bring to a boil, then reduce heat and simmer uncovered for 25–30 minutes, until lentils are tender.
- Cook the Potatoes: While the stew simmers, add chopped potatoes to a separate pot and cover with cold water. Bring to a boil and cook for 15–20 minutes, until fork-tender. Drain and keep warm.
- Finish the Mashed Potatoes: Mash the potatoes while still hot. Add vegan butter and mix until melted. Slowly add warm soy milk (start with 1/4 cup) until creamy. Season generously with salt.
- Thicken the Stew: Remove and discard the bay leaf. Stir in the cornstarch slurry and simmer for 2–3 minutes. Remove about 1 cup of the stew, blend until smooth, then stir back in. Taste and adjust seasoning.
- Serve: Spoon mashed potatoes into bowls. Ladle thick lentil stew over top. Finish with black pepper or fresh herbs if desired.
Expert Tips & Troubleshooting
- Start with 4 cups of broth only for a thicker, gravy-style stew. You can always thin it out later if desired.
- Don’t forget to take the bay leaf out before serving or blending a portion of the stew.
Troubleshooting: If your stew is too thin, mix a tablespoon of cornstarch with a tablespoon of cold water, stir it in, and simmer for another 2-3 minutes. If your mashed potatoes are gummy, it means they were over-mashed. Always mash just until smooth
