Ingredients
  

  • 1.5 cups dry green or brown lentils rinsed
  • 1 lb mushrooms cremini or portobello, sliced or quartered
  • 2 large russet potatoes peeled and cut into 1-inch chunks
  • 3 medium carrots peeled and sliced into rounds
  • 2 parsnips or turnips peeled and chopped
  • 1 large yellow onion diced
  • 3 cloves garlic minced
  • 2 tablespoons tomato paste
  • 1 can (14.9 oz) Guinness or Irish Stout optional; swap with extra broth
  • 5-6 cups vegetable broth
  • 2 tablespoons olive oil
  • 2 bay leaves
  • 1 teaspoon dried thyme or 3 sprigs fresh
  • 1 teaspoon smoked paprika
  • salt and black pepper to taste
  • 2 tablespoons all-purpose flour or cornstarch for gluten-free
  • 1 tablespoon soy sauce or Worcestershire sauce vegetarian version

Equipment

  • Large Dutch oven or heavy-bottomed pot
  • wooden spoon
  • Fine-mesh strainer

Method
 

  1. Heat olive oil in a large Dutch oven or heavy-bottomed pot over medium heat. Add diced onion and sliced carrots, sautéing for about 5 minutes until onion becomes translucent and carrots begin to soften.
  2. Add mushrooms to the pot. Cook for 5-7 minutes, stirring occasionally, until mushrooms release moisture, it evaporates, and they turn golden brown. Add minced garlic during last minute and cook until fragrant.
  3. Stir in tomato paste and flour, coating all vegetables. Cook for 1-2 minutes, stirring constantly, to toast flour and intensify tomato paste flavor. Pour in Guinness (or extra broth) and scrape up all browned bits from bottom of pot. Let simmer for 2 minutes to reduce slightly.
  4. Add rinsed lentils, potato chunks, chopped parsnips, vegetable broth, bay leaves, thyme, and smoked paprika. Stir thoroughly. Liquid should cover vegetables and lentils by about an inch—add more broth if needed. Bring to a rolling boil over high heat.
  5. Reduce heat to low, cover pot with lid, and simmer gently for 35-45 minutes, stirring occasionally, until lentils are completely tender with no chalky center and potatoes can be easily pierced with a fork.
  6. Remove bay leaves and thyme sprigs. Stir in soy sauce or vegetarian Worcestershire sauce. Taste broth and adjust seasoning with salt and black pepper. If stew seems too thin, continue simmering uncovered for 5-10 minutes to reduce and concentrate flavors.
  7. Ladle into deep bowls, ensuring each serving gets a mix of lentils, potatoes, carrots, parsnips, and mushrooms. Garnish with fresh chopped parsley.

Notes

Storage: Store in airtight containers for up to 5 days or freeze for up to 3 months. Flavors improve after a day or two. Lentils will absorb liquid—add broth when reheating. Lentil type: Use green or brown lentils for best texture. Red lentils dissolve and change the character. Guinness substitute: Use extra vegetable broth plus 1 tbsp balsamic vinegar and 1 tsp molasses to mimic malty depth. Thickness: Stew naturally thickens as lentils break down. Mash a few potato chunks for thicker stew, add broth for thinner. Protein boost: Stir in white beans during last 10 minutes or top with hemp seeds. Gluten-free: Use cornstarch instead of flour and gluten-free Worcestershire sauce. Slow cooker: Sauté vegetables and deglaze first, then transfer to slow cooker. Cook on Low 6-7 hours or High 3-4 hours.
