Ingredients
- 2 tbsp olive oil
- 1 large onion, finely sliced
- 2 garlic cloves, minced
- 1 red bell pepper, chopped
- 1 yellow bell pepper, chopped
- 2 medium carrots, peeled and sliced
- 1 medium courgette (zucchini), sliced
- 200g cherry tomatoes, halved
- 150g green beans, trimmed and halved
- 1 medium aubergine (eggplant), diced
- 1 tsp dried oregano
- 1 tsp dried thyme
- 1 tsp smoked paprika
- 400g canned chopped tomatoes
- 100ml vegetable stock
- Salt and freshly ground black pepper, to taste
- A handful of fresh basil leaves, roughly chopped
- Fresh parsley, chopped, to garnish (optional)
- Juice of half a lemon
Instructions
- Preheat your oven to 190°C (375°F) fan/gas mark 5.
- Heat the olive oil in a large, ovenproof frying pan or casserole dish over medium heat. Add the sliced onion and garlic, cooking gently for 5 minutes until softened but not browned.
- Add the chopped red and yellow bell peppers, carrots, courgette, green beans, and aubergine to the pan. Stir well and cook for another 8-10 minutes, stirring occasionally, until the vegetables start to soften.
- Sprinkle in the dried oregano, thyme, and smoked paprika, stirring to combine and release their aromas.
- Pour in the canned chopped tomatoes and vegetable stock, stirring well to combine. Season generously with salt and pepper.
- Bring the mixture to a gentle simmer, then scatter the halved cherry tomatoes over the top. Let it cook uncovered for 5 minutes to allow some of the liquid to reduce.
- Transfer the pan or casserole dish to the preheated oven. Bake uncovered for 35-40 minutes, until the vegetables are tender and the sauce has thickened.
- Remove from the oven and stir in the fresh basil leaves and lemon juice to brighten the flavors.
- Garnish with chopped parsley if using, then serve hot.
Tips
- Vegetable substitutions: Feel free to swap in seasonal vegetables like butternut squash, sweet potatoes, or broccoli depending on what’s available or your preference.
- Make it spicier: Add a pinch of chili flakes or a diced fresh chili when cooking the onions and garlic for a gentle heat.
- Use fresh herbs: If you have fresh oregano or thyme, use about 1 tbsp chopped instead of dried for a brighter, fresher taste.
- Common mistake: Avoid overcrowding the pan when sautéing vegetables; cook in batches if needed to ensure they soften evenly and don’t steam.
Serving Suggestions
This vegetable casserole works wonderfully as a standalone vegetarian main or as a side dish. Serve it with a crusty wholegrain bread or garlic bread to soak up the rich tomato sauce. For a more substantial meal, pair it with cooked quinoa, brown rice, or couscous. A fresh green salad with a tangy vinaigrette complements the warmth of the casserole perfectly.
Variations
While this recipe avoids cheese, you can customize it to your taste. Add cooked chickpeas or cannellini beans for extra protein and texture. For a Mediterranean twist, stir in some olives and capers before baking. To keep it vegan, ensure your vegetable stock is free from animal products. If you prefer a creamier texture, swirl in coconut cream or a dollop of cashew cream just before serving.
Storage and Reheating
Store any leftover vegetable casserole in an airtight container in the refrigerator for up to 3 days. When reheating, cover the casserole with a lid or foil and warm it gently in the oven at 160°C (320°F) for about 15-20 minutes until heated through. Alternatively, microwave individual portions on medium power for 2-3 minutes, stirring halfway. This casserole also freezes well; freeze in portions for up to 2 months and thaw overnight in the fridge before reheating.
Frequently Asked Questions
Can I make this vegetable casserole ahead of time?
Yes, this dish is ideal for preparing in advance. You can assemble the casserole a day before and store it covered in the fridge, then bake it fresh just before serving. This helps the flavors meld even better.
What if I don’t have an ovenproof pan?
If you don’t have an ovenproof pan, cook the vegetables and sauce in a regular skillet, then transfer everything to a baking dish before putting it in the oven.
How do I keep the vegetables from getting mushy?
To avoid mushy vegetables, cut them into uniform sizes and avoid overcooking during the stovetop step. Baking uncovered helps excess moisture evaporate, so the casserole thickens nicely without turning soggy.
Is this casserole suitable for vegans?
Absolutely. By omitting cheese and ensuring your vegetable stock contains no animal products, this casserole is fully vegan and packed with plant-based nutrition.
Can I add grains or pasta to make it more filling?
You can stir in cooked grains like quinoa or barley after baking, or serve the casserole over cooked pasta or rice to bulk out the meal and add texture.
What’s the best way to reheat without drying it out?
Reheat gently in the oven covered with foil or with a microwave-safe lid to retain moisture. You can also add a splash of vegetable stock or water before reheating if the casserole looks dry.
This Jamie Oliver-inspired vegetable casserole recipe offers a flexible, flavorful way to enjoy seasonal vegetables without cheese. Its balanced seasoning and simple technique make it perfect for everyday meals or batch cooking, providing a tasty, wholesome option for all diets.
