Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Ricotta Lasagne
Serves 12Ingredients
Directions
Make the sauce
Remove sausage casings, and break sausage into small bits.
Sauté sausage and ground beef in 5-quart (4.7 L) saucepan or Dutch oven over medium heat with onion and garlic until the meat is browned.
Add sugar, 1 tablespoon salt, basil, fennel, pepper, and half the parsley; mix well.
Add tomatoes, tomato paste and water, mashing the tomatoes a bit. Bring the sauce to a boil then reduce heat and simmer, covered and stirring occasionally for 1½ hours.
Prepare the filling
Preheat oven to 275 °F (135 °C).
Cook and drain pasta.
In a medium bowl mix ricotta, egg, ½ teaspoon salt and remaining parsley.
Assemble and bake
Assemble your lasagna in a 13×9×2‑inch (33×23×5.1‑cm) roasting pan (listed bottom to top): Bottom layer of sauce (approx. 1½ cups / 375 g / 13.2 oz). Layer of pasta (overlapping slightly). Layer of ½ the ricotta mixture. Layer of ⅓ of the mozzarella. Sauce layer (again, about 1½ cups / 375 g / 13.2 oz). Layer of grated Parmesan sprinkled over sauce (not so much that the sauce layer is covered entirely). Layer of pasta. Layer of remaining ricotta. Layer of ⅓ of the mozzarella. Layer of remaining sauce. Layer of sprinkled Parmesan. Layer of remaining mozzarella.
Cover the lasagna with foil and bake 30 minutes covered, then 25 minutes uncovered (or until bubbly and lightly browned). Cool for at least 20 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned whole tomatoes
- Provide the main sauce body and bright acidity that balances the rich meat and cheese.
- Tomato paste
- Adds concentrated tomato flavor and helps thicken the sauce as it simmers.
- Ricotta cheese
- Creates a soft, creamy layer that stays moist and tender after baking.
- Egg
- Binds the ricotta mixture so it holds together between the layers.
- Mozzarella cheese
- Melts into stretchy layers and gives the top a golden, bubbly finish.
- Lasagna pasta
- Forms the structural sheets that hold the layers together when sliced.
The step that matters
Cool for at least 20 minutes before serving. As the lasagna cools, the starches, cheeses and sauce firm up and set. Cutting it hot lets the layers slide apart and the filling run out.
Swap the onion
How well each one fits the dish's main ingredients (beef, clove, garlic, sugar, basil, fennel, pepper):
- Capsicumfits better
