Instructions
Begin by heating the rapeseed oil in a large, heavy-based pan over medium heat. Add the finely chopped onion and cook gently for 5 to 10 minutes, stirring occasionally, until the onions soften and become translucent, releasing their sweetness. Next, stir in the minced garlic along with the warming spices: paprika and cumin. Sprinkle in the dried thyme, followed by diced carrots, celery, and both red and yellow peppers. Cook this aromatic vegetable mixture for 5 minutes, allowing the spices to infuse thoroughly. Pour in the tinned tomatoes along with the vegetable stock, then add the sliced courgettes and fresh thyme sprigs. Let the casserole simmer for 20 to 25 minutes; during this time, the flavors meld beautifully, and the vegetables become tender. Before serving, carefully remove the thyme sprigs. Stir in the lentils and return the pan to a gentle simmer to warm the lentils through. This final step ensures the lentils absorb the savory stew's essence. For a delicious finish, serve the casserole over a bed of fluffy wild and white basmati rice, creamy mash, or a scoop of quinoa. Tip: To add extra texture and interest, garnish with fresh herbs or a dollop of yogurt.
