Ingredients
- 3 tbsp olive oil
- 2 large onions, peeled and sliced
- 4 garlic cloves, finely chopped
- 3 medium carrots, peeled and diced
- 2 red bell peppers, deseeded and chopped
- 2 courgettes (zucchini), chopped into chunks
- 2 aubergines (eggplants), chopped into chunks
- 800g canned chopped tomatoes (2 standard tins)
- 2 tbsp tomato purée
- 200ml vegetable stock (low sodium preferred)
- 1 tsp dried oregano
- 1 tsp dried thyme
- 1 tsp smoked paprika
- Salt and freshly ground black pepper, to taste
- Handful fresh basil leaves, roughly torn
- Handful fresh parsley, chopped
- 150g mature cheddar or mozzarella, grated (optional)
- Fresh crusty bread or cooked rice, to serve
Instructions
- Preheat your oven to 190°C (375°F) fan/gas mark 5.
- Heat 2 tablespoons of olive oil in a large, heavy-based ovenproof casserole dish over medium heat.
- Add the sliced onions and sauté gently for 5–7 minutes until soft and translucent but not browned.
- Stir in the chopped garlic and cook for another 1 minute until fragrant.
- Add the diced carrots, red peppers, courgettes, and aubergines. Cook for 10 minutes, stirring occasionally, until the vegetables start to soften and reduce in volume.
- Mix in the chopped tomatoes, tomato purée, and vegetable stock, stirring well to combine.
- Season with oregano, thyme, smoked paprika, salt, and pepper. Give everything a good stir.
- Bring the mixture to a gentle simmer on the stovetop, then cover the casserole dish with its lid or foil and transfer to the preheated oven.
- Bake for 45 minutes, stirring halfway through to ensure even cooking.
- Remove the lid or foil, sprinkle the grated cheese evenly over the top if using, and return to the oven uncovered for another 10–15 minutes until the cheese is melted and golden.
- Remove from the oven and stir through the fresh basil and parsley just before serving to keep the herbs bright and fresh.
- Serve hot with crusty bread or alongside cooked rice for a filling family meal.
Tips
- Vegetable substitutions: Feel free to swap in seasonal vegetables like butternut squash, green beans, or mushrooms depending on availability and preference.
- Make it vegan: Simply omit the cheese or use a plant-based cheese alternative to keep the dish vegan-friendly.
- Don’t overcrowd the pan: When sautéing the vegetables, cook in batches if needed to avoid steaming and ensure they caramelize slightly for deeper flavor.
- Storage: Cool leftover casserole completely before refrigerating in an airtight container. It will keep well for up to 3 days.
Serving Suggestions
This vegetable casserole is wonderfully versatile. Serve it as a main dish with a side of fluffy rice, couscous, or warm crusty bread to soak up all the juices. For a heartier meal, add a dollop of Greek yogurt or a side salad with lemon vinaigrette to balance the richness. It also pairs well with grilled chicken or baked fish for non-vegetarian options.
Variations
You can easily customize this casserole to suit different tastes or dietary needs. For a Mediterranean twist, add a handful of pitted black olives and a sprinkle of feta cheese before serving. To boost protein, stir in cooked chickpeas or lentils along with the vegetables. For a spicy kick, include a chopped fresh chili or a teaspoon of chili flakes. If you prefer a creamier texture, swirl in some crème fraîche or coconut milk just before serving.
Storage and Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, transfer the casserole to an ovenproof dish and warm it through at 160°C (320°F) for 20–25 minutes, covered with foil to prevent drying out. Alternatively, microwave individual portions on medium power for 2–3 minutes, stirring halfway. Avoid reheating more than once to maintain quality and food safety.
