Ingredients Overview

Each ingredient in this stew plays a role in building layers of flavor and nutrition.

Vegetables & Aromatics

• Onion: Yellow or white adds sweet aromatic depth.

• Garlic: Key to rich, earthy flavor.

• Carrots & Celery: A classic mirepoix base that provides subtle sweetness and texture.

• Mushrooms: Use cremini, baby bella, or a mix — the heart of the stew. Sautéed until browned for maximum umami.

• Tomato Paste: Adds depth, richness, and body to the broth.

Lentils

• Brown or Green Lentils: Hold their shape well and create a hearty, meaty texture.

• Avoid red lentils as they break down and create a mushier consistency.

Broth & Liquids

• Vegetable Broth: Use low-sodium to control saltiness.

• Balsamic Vinegar or Red Wine: Adds complexity and a subtle tang.

• Tamari or Soy Sauce: Boosts umami (optional, but great for depth).

Herbs & Seasoning

• Thyme & Rosemary: Earthy and aromatic — fresh or dried both work.

• Bay Leaf: For background warmth.

• Smoked Paprika (Optional): Adds gentle smokiness.

• Salt & Pepper: To taste.

Optional Additions

• Kale or Spinach: Stir in at the end for extra greens.

• Potatoes: Diced and simmered for a thicker, chunkier stew.

• Nutritional Yeast: For a cheesy, savory flavor boost.
