Classic Beef Lasagna

A classic beef lasagna takes some time, but none of it is complicated. The two things that decide whether it slices into neat layers or slides apart are a sauce that has simmered long enough to thicken and a proper rest after baking. This recipe uses ground beef with Italian sausage for a more seasoned sauce, and a ricotta layer bound with egg so it stays creamy rather than runny.

What Makes This Version Work

Beef plus sausage. Ground beef gives the sauce body, while mild Italian sausage brings fennel, garlic and fat that season the whole pan. The combination tastes fuller than beef alone without extra spices.

A 20-minute simmer. Canned tomatoes are watery. Simmering the sauce uncovered evaporates some of that water and concentrates the flavor. A thick sauce is the first defense against a soupy lasagna.

Egg in the ricotta. The beaten egg sets as it bakes, holding the ricotta layer together so it does not ooze out when you cut. Parmesan and a pinch of nutmeg season it so the layer tastes like more than plain cheese.

Resting before slicing. Straight from the oven, the cheese and sauce are molten. Fifteen to twenty minutes on the counter lets them firm up so each slice holds its layers.

Ingredient Notes

• 80/20 ground beef: Leaner beef makes a drier sauce. Drain off most of the fat, leaving about a tablespoon for flavor.
• Italian sausage: Mild keeps it family-friendly; hot sausage adds a kick. You can use all beef (2 pounds) and add ½ teaspoon fennel seed.
• Whole-milk ricotta: Part-skim is grainier and wetter. If your ricotta has liquid on top, drain it in a fine sieve for 15 minutes. Cottage cheese, blended until smooth, is a common swap.
• Mozzarella: Low-moisture shredded mozzarella melts without releasing water. Fresh mozzarella tastes great but makes the lasagna wetter.
• Noodles: Regular noodles boiled al dente or oven-ready noodles both work. With oven-ready noodles, add ½ cup of water to the sauce, since they absorb more liquid as they bake.

Assembly and Baking Cues

Brown the meat until no pink remains and some bits are crisp, about 8 to 10 minutes. The sauce is ready when it mounds slightly on a spoon instead of running off.

Lay boiled noodles flat on parchment or an oiled sheet so they do not stick together while you work. Start the dish with a thin layer of sauce so the bottom noodles do not stick or dry out.

Tent the foil so it does not touch the cheese. After 25 minutes covered and 20 uncovered, the edges should bubble and the top should have browned spots. A knife inserted in the center should slide through all the noodles with no resistance.

Common Mistakes

• Watery lasagna. A thin sauce, wet ricotta or fresh mozzarella. Simmer the sauce, drain the ricotta and use low-moisture cheese.
• Overcooked noodles. Boil them 2 minutes less than the package says. They finish cooking in the oven.
• Cutting right away. The layers slide apart. Wait at least 15 minutes.
• Burnt cheese on the foil. Spray the underside of the foil with cooking spray, or tent it high.

Variations

• Spinach layer: Stir 10 ounces of thawed, squeezed-dry frozen spinach into the ricotta mixture.
• Mushroom and beef: Sauté 8 ounces of sliced mushrooms with the onion.
• Skillet lasagna: Break noodles into the simmering sauce with 1 cup of water, cover and cook 15 minutes, then dollop with ricotta and mozzarella.
• Smaller batch: Halve the recipe and bake in an 8×8 dish for about 35 minutes total.

Make-Ahead, Freezing and Reheating

Assemble the lasagna up to 24 hours ahead, cover tightly and refrigerate. Bake covered for 40 minutes, then uncovered for 20 minutes, since it starts cold.

To freeze, assemble in a freezer-safe dish, wrap in plastic and foil, and freeze up to 3 months. Thaw overnight in the refrigerator before baking as above. Baked leftovers keep 4 to 5 days in the refrigerator; reheat individual slices covered in the microwave at 70% power, or warm the whole pan covered at 350°F for 25 to 30 minutes.

Frequently Asked Questions

Do I have to boil the lasagna noodles?

Only if they are regular noodles. Oven-ready noodles go in dry; add ½ cup of water to the sauce so they have enough liquid to cook.

Why is there liquid in the bottom of my lasagna?

The sauce was thin or the ricotta was wet. Simmer the sauce longer and drain the ricotta before mixing.

Can I use cottage cheese instead of ricotta?

Yes. Use small-curd cottage cheese, drained, and blend it until smooth for a texture close to ricotta.

How do I keep the top from burning?

Keep it covered for the first 25 minutes. If it browns too fast during the uncovered stage, lay the foil loosely back over the top.

Method

 

1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with cooking spray.
2. In a large Dutch oven or skillet over medium heat, add 1.5 lb ground beef and 0.5 lb mild Italian sausage. Cook for 8 to 10 minutes, breaking up the meat with a wooden spoon until fully browned.
3. Add 1 finely diced yellow onion and 4 minced garlic cloves to the meat. Sauté for 4 to 5 minutes until the onion becomes soft and translucent.
4. Drain excess grease from the pan, leaving about 1 tablespoon for rich flavor.
5. Stir in 2 tbsp tomato paste, 1 can (28 oz) crushed tomatoes, 1 can (15 oz) tomato sauce, 2 tsp dried Italian seasoning, 1 tsp granulated sugar, 1 tsp salt, and 0.5 tsp black pepper.
6. Bring the sauce to a low simmer, lower the heat, and cook uncovered for 20 minutes, stirring occasionally.
7. While the sauce simmers, cook 12 lasagna noodles in a large pot of boiling salted water according to package directions until al dente. Drain and lay flat on parchment paper.
8. In a medium bowl, combine 15 oz ricotta cheese, 1 beaten egg, 0.25 cup chopped parsley, 0.5 tsp salt, 0.25 tsp ground nutmeg, and 0.5 cup grated Parmesan cheese. Stir until smooth.
9. Spread 1 cup of the meat sauce evenly over the bottom of the prepared 9x13-inch baking dish.
10. Arrange 4 lasagna noodles side-by-side over the sauce, slightly overlapping if needed.
11. Spread half of the ricotta cheese mixture evenly over the noodles, then sprinkle with 5 oz shredded mozzarella cheese and 1 cup meat sauce.
12. Repeat with a second layer: 4 noodles, remaining ricotta mixture, 5 oz mozzarella, and 1 cup meat sauce.
13. Top with the final 4 noodles, remaining meat sauce, remaining 6 oz mozzarella cheese, and remaining 0.5 cup Parmesan cheese.
14. Cover the baking dish loosely with aluminum foil, ensuring it does not touch the top cheese layer, and bake at 375°F for 25 minutes.
15. Remove the foil and bake uncovered for an additional 20 minutes until the cheese is melted, bubbly, and golden brown.
16. Remove from the oven and let the lasagna rest for 15 to 20 minutes before slicing and serving.
