Ingredients You’ll Need
- 500g frozen cheese ravioli (do not thaw)
- 2 tablespoons olive oil
- 1 large onion, finely diced
- 4 cloves garlic, minced
- 800g tinned chopped tomatoes
- 2 tablespoons tomato purée
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- ½ teaspoon chilli flakes (optional)
- 250g ricotta cheese
- 1 large egg
- 200g mozzarella, grated
- 100g Parmesan cheese, finely grated
- Salt and black pepper, to taste
- Fresh basil leaves, for garnish (optional)
Tip: Use a good-quality tinned tomato — it’s the backbone of the sauce and makes a noticeable difference in depth of flavour.
How to Make Cheesy Baked Cheese Ravioli Casserole
- Preheat the oven to 190°C (fan-assisted). While it heats, drizzle the olive oil into a large, ovenproof baking dish (roughly 30cm x 20cm) and set it aside. You want the oven fully up to temperature before the casserole goes in — this ensures the top browns evenly.
- Sweat the aromatics: In a large frying pan over medium heat, add a splash of olive oil and cook the diced onion for about 5 minutes, until it turns translucent and releases a sweet, fragrant smell. Stir in the garlic and cook for another minute — the garlic should become aromatic but not brown, otherwise it will taste bitter.
- Build the sauce: Pour in the tinned tomatoes and tomato purée, then add the oregano, basil, chilli flakes if using, and a generous pinch of salt and pepper. Stir well and bring to a gentle simmer. Let it bubble away for 8–10 minutes, stirring occasionally, until the sauce thickens slightly and turns a deep, rich red colour. You’ll notice the raw tomato smell mellow into something savoury and inviting.
- Prepare the ricotta mixture: In a small bowl, combine the ricotta cheese with the egg, half the grated Parmesan, and a pinch of salt. Whisk until smooth and creamy — the texture should be spreadable but not runny, like a thick yoghurt.
- Layer the casserole: Spread a thin layer of the tomato sauce (about a third of it) across the bottom of the prepared baking dish. Arrange half the frozen ravioli in a single layer over the sauce — they can touch slightly but shouldn’t overlap too much. Dollop half the ricotta mixture over the ravioli and spread it gently with the back of a spoon. Sprinkle a third of the grated mozzarella over the top. Repeat the layers: another third of the sauce, the remaining ravioli, the remaining ricotta, and another third of the mozzarella. Finish with the final third of sauce spread evenly across the top, then scatter the remaining mozzarella and the rest of the Parmesan over everything.
- Bake until bubbling and golden: Place the dish in the preheated oven and bake for 30–35 minutes. You’re looking for the sauce to be bubbling vigorously around the edges — you’ll hear it hissing — and the cheese on top to turn a deep golden brown with darker patches. If the top isn’t browning enough after 30 minutes, switch the oven to grill for the final 3–5 minutes, watching closely so it doesn’t burn.
- Rest before serving: Remove the casserole from the oven and let it sit on the counter for a full 10 minutes. This rest time allows the layers to set, so when you cut into it, the pieces hold their shape rather than turning into a soupy mess. Garnish with fresh basil leaves if desired, then serve straight from the dish.
Tips From My Kitchen
- Don’t thaw the ravioli: Frozen ravioli cooks perfectly in the oven from frozen. If you thaw it first, the pasta becomes mushy and the layers turn watery. Keep them solid until the moment they hit the dish.
- Use a deep baking dish: A shallow dish causes the sauce to evaporate too quickly, leaving you with dry pasta. A dish at least 7cm deep traps steam and keeps everything moist and tender.
- Season every layer: Sprinkle a tiny pinch of salt between each ravioli layer. This ensures the seasoning penetrates throughout, rather than just sitting on top. The ricotta mixture also needs salt to bring out its creaminess.
- Make it ahead for busy nights: Assemble the entire casserole up to 24 hours in advance, cover tightly with foil, and refrigerate. When ready to bake, add 10–15 minutes to the cooking time since the dish starts cold. This is my go-to strategy for hectic weekdays.
- Double the batch, freeze one: This casserole freezes beautifully. Assemble it in a foil dish, wrap tightly in two layers of cling film and one of foil, and freeze for up to three months. Bake from frozen at 180°C for 50–60 minutes, removing the covering for the last 10 minutes.
- Grate your own mozzarella: Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly. Grating a block yourself gives you a luscious, stretchy topping that browns beautifully.
Common Mistakes to Avoid
- Overcrowding the pan: If you cram too many ravioli into the dish, they steam rather than bake, resulting in a gummy texture. Leave a little space between pieces so the sauce can bubble up around them, allowing even cooking and a pleasant bite.
- Wrong temperature: Baking at too low a temperature (below 180°C) makes the sauce watery and the pasta soggy because it takes too long to heat through. Stick to 190°C fan-assisted for a firm, golden result. If your oven runs hot, check it at 25 minutes.
- Skipping the rest time: Cutting into the casserole straight from the oven causes the layers to slide apart and the sauce to flood the plate. That 10-minute rest lets the starches in the pasta absorb excess liquid and the cheese to set, giving you clean, neat servings every time.
Delicious Variations to Try
- Spicy Version: Add 1–2 finely chopped fresh red chillies to the onion and garlic, or stir a teaspoon of harissa paste into the tomato sauce. The heat cuts through the richness of the cheese beautifully.
- Vegetarian/Vegan Option: Use a plant-based ricotta (soy or almond-based works well) and vegan mozzarella shreds. Replace the egg in the ricotta mixture with a tablespoon of cornflour mixed with two tablespoons of water to help it bind. The rest of the recipe remains unchanged.
- Different Protein: Brown 400g of minced beef or turkey with the onion before adding the garlic. Drain any excess fat, then proceed with the sauce. Alternatively, stir in 200g of cooked, shredded chicken between the ravioli layers for a lighter option.
What to Serve With Cheesy Baked Cheese Ravioli Casserole
- A simple green salad with a lemony vinaigrette — the acidity balances the richness of the casserole.
- Garlic bread or crusty baguette to mop up any extra sauce from the plate.
- Steamed broccoli or green beans tossed in butter and a pinch of salt for a quick vegetable side.
- Roasted cherry tomatoes on the vine, drizzled with olive oil and balsamic vinegar, for a burst of sweetness.

Frequently Asked Questions
Can I use fresh ravioli instead of frozen?
Yes, you can substitute fresh ravioli directly — no need to thaw or pre-cook it. Reduce the baking time by about 5–10 minutes, as fresh pasta cooks faster. Keep an eye on the cheese topping to ensure it doesn’t burn.
How do I store leftovers?
Transfer any cooled leftovers to an airtight container and refrigerate for up to four days. To reheat, spoon a portion into a microwave-safe dish and heat in 30-second bursts, stirring gently, or reheat in a 180°C oven for 15 minutes covered with foil to prevent drying out.
Can I add vegetables to the casserole?
Absolutely. Sautéed spinach, sliced courgettes, or roasted aubergine all work well. Layer them between the ravioli and sauce, or stir them into the tomato sauce before assembling. Just ensure any watery vegetables are cooked first to release their moisture, otherwise the casserole may become too liquid.
Why is my casserole watery?
A watery casserole usually results from using thawed ravioli or not cooking the sauce down enough. The sauce should be thick enough to coat the back of a spoon before layering. Also, avoid adding extra liquid like broth or water — the ravioli releases some moisture as it cooks, which is sufficient.
Can I make this gluten-free?
Yes, simply substitute gluten-free frozen ravioli, which is widely available. Check the labels on your ricotta and Parmesan to ensure they are gluten-free (most are). The rest of the ingredients are naturally gluten-free, so the recipe adapts seamlessly.
