Step-By-Step Instructions
Step 1 – Grate the carrots and mushrooms, chop the pepper, onion, and garlic, then cook in a little olive oil until softened. Step 2 -Stir in the spices and herbs — and cook for another minute to release their flavour. Step 3 – Add the chopped tomatoes. Step 4 – Add harissa paste and balsamic vinegar. Mix well and let everything simmer gently for about 10 minutes. Step 5 – Add the drained lentils, and stock. Stir and cook until it thickens.
Tips
- Grate vegetables finely: Finely grate carrots and mushrooms to create a smoother texture and help the vegetables blend seamlessly into the sauce, enhancing the overall consistency.
- Adjust spice level: For a milder flavour, skip the harissa or replace it with smoked paprika.
- Simmer to deepen flavour: Allow the chilli to simmer gently for at least 15-20 minutes after adding the lentils and spices. This slow cooking helps the flavours develop fully and thickens the sauce naturally.
- Use fresh herbs for garnish: Adding fresh coriander or parsley just before serving brightens the dish and adds a refreshing contrast to the rich, spicy base.
- Perfect for meal prep: This chilli keeps well in the fridge for up to 3 days and freezes beautifully. Prepare a big batch ahead of time for easy, nutritious meals throughout the week.
- Serve with healthy sides: Pair your lentil chilli with naan, brown rice, or toasted wraps for a balanced, fibre-rich meal that’s satisfying and wholesome. Try my 3-Ingredient Quick & Easy Flatbread
Swaps
Green lentils: You can swap with red or brown lentils, but cooking times may vary slightly. Red lentils tend to break down more, creating a softer texture.
Carrots: Try grated sweet potato or butternut squash for a naturally sweet twist and extra vitamins.
Red pepper: Use yellow or orange peppers for a milder, sweeter flavour or swap with courgette for a lighter texture.
Mushrooms: Swap with finely chopped eggplant or zucchini for a different earthy note and moisture.
Harissa paste: Use smoked paprika and a pinch of cayenne pepper if you don’t have harissa, or mild chili powder for less heat.
Balsamic vinegar: Substitute with apple cider vinegar or lemon juice to add acidity and brightness.
Chopped tomatoes: Use fresh ripe tomatoes blended or canned passata for a smoother sauce.
Vegetable stock cube: Use a low-sodium broth or homemade stock to control salt levels and enhance flavour naturally.
What to Serve It With
- Steamed rice or quinoa for a filling meal
