- Step 7: Remove from the oven, scatter with extra basil leaves, and serve warm, ideally with a fresh green salad.
Tips & Variations
- Use fresh chilli or chilli flakes if you prefer a spicier sauce.
- Substitute mozzarella with provolone or fontina for a different cheesy flavor.
- For a meaty twist, add cooked sausage or ground beef to the tomato sauce.
- Use gluten-free spaghetti to make this dish gluten-free.
- Adding a splash of cream to the tomato sauce can make it richer and more indulgent.

FAQs
Can I use fresh tomatoes instead of canned?
Yes, you can use fresh tomatoes. Use about 800g of ripe tomatoes, chopped, and simmer a bit longer to break them down and thicken the sauce.
Is it necessary to break the spaghetti into short lengths?
Breaking the spaghetti helps it layer more evenly and makes the dish easier to serve, but you can leave the pasta whole if you prefer.

Instructions
- Prepare the tomato sauce: Heat the oven to 200C/180C fan/gas 6. In a large pan, warm the olive oil over medium heat. Add the chopped garlic and fry for 1 minute until fragrant but not browned. Stir in the canned chopped tomatoes and a good pinch of chilli powder. Season with salt and pepper. Bring the mixture to a boil, then reduce the heat and simmer gently for 10 minutes, allowing the flavors to meld and the sauce to thicken slightly.

- Combine spaghetti and sauce: Return the drained spaghetti to the pot or a large bowl, then mix in the tomato sauce along with a handful of fresh basil leaves. Toss gently to combine evenly.
- Assemble the bake: Spoon half of the spaghetti mixture into a large ovenproof dish, spreading it out evenly. Arrange half the sliced mozzarella over the top, then sprinkle with half of the grated Parmesan cheese. Repeat the layers with the remaining spaghetti mixture, mozzarella, and Parmesan.
