This tomato Mozzarella pasta bake is our Sunday family dinner: 500 g penne, 800 g passata, 250 g Mozzarella, 100 g Parmesan, a handful of basil. Total time is 60 minutes, with just 15 minutes of active work. The Thermomix® handles the sauce and slicing in 10 minutes, and the oven does the rest. Makes 4 generous portions, often enough for two days.
We make this for family Sundays and for meal prep (divide into 4 containers, reheat the next day in the oven or microwave). Vegetarian, family-friendly, and with the right ingredients a proper Italian classic, not a ready-made bake from the chiller aisle.

Which tomatoes make or break the bake
Sieved San Marzano tomatoes are the best thing we can buy for Italian sauces. These varieties are low in acidity, fruity, and regulated under the official DOP standard (protected designation of origin). Mutti Polpa or Cirio Polpa work equally well. Discount passata without a brand name often contains too much water and too little tomato, and the bake turns watery.
Many recipe sites and Cookidoo simply write “passata” without specifying quality. We recommend DOP tomatoes or Italian branded varieties. The difference in flavour is noticeable, and the price difference is around 50 cents per jar.

The Bufala question with Mozzarella
Mozzarella di Bufala (made from buffalo milk) has 50% more fat than Fior di Latte (made from cow’s milk), which gives the bake more creaminess. For a pasta bake, though, Fior di Latte works perfectly well, because the Bufala flavour is largely lost during baking. If you use 250 g Mozzarella: put 200 g into the bake and 50 g on top, so the cheese pulls into nice strings when melted.
Drain the Mozzarella on kitchen paper for 10 minutes before using. Otherwise a lot of liquid ends up in the bake and makes it soggy. Dry Mozzarella plus a rich tomato base is the key to success.

Pasta half-cooked, sauce concentrated
As with any pasta bake: cook the pasta for only 5 minutes instead of the full 11. It will finish cooking in the oven with the sauce. Simmer the sauce in the Thermomix® with garlic, onion, olive oil, tomatoes, salt, pepper and 1 tsp sugar for 10 minutes at 100°C on speed 1. The sugar balances the acidity of the tomatoes, which is the classic Italian method from Marcella Hazan’s standard work “Essentials of Classic Italian Cooking”.

Layer, bake, rest
In a baking dish (25 x 35 cm), start with a thin layer of tomato sauce, then the pasta, then the tomato and Mozzarella mix, then Parmesan on top. Bake for 25 minutes at 200°C top and bottom heat, then switch on the grill for the final 3 minutes for a golden crust. Leave to rest for 5 minutes after baking so the bake cuts cleanly into portions.

Six variations to keep things interesting
With chicken (300 g cooked diced chicken breast), with spinach (200 g frozen spinach stirred into the sauce), four-cheese version (Mozzarella, Gorgonzola, Parmesan and Pecorino), spicy (1 tsp chilli flakes in the sauce plus salami), Greek-style (feta instead of Mozzarella, olives and oregano), vegan (vegan Mozzarella alternative and nutritional yeast instead of Parmesan).
