Oven-baked lasagna is a classic comfort food. Layers of pasta, rich meat sauce, creamy cheese, and tangy tomato sauce melt together in the oven. This dish feeds a crowd. It also freezes well for later meals. Follow this guide for perfect results every time.
Making lasagna from scratch takes time. Plan ahead. You need about 2 hours total. This includes prep and baking. The recipe serves 8 to 10 people. Use a 9×13-inch baking dish.
Gather Your Ingredients
For the Meat Sauce:
- 1 pound ground beef
- 1 pound Italian sausage
- 1 onion (chopped)
- 3 garlic cloves (minced)
- 2 cans (28 ounces each) crushed tomatoes
- 1 can (15 ounces) tomato sauce
- 2 tablespoons tomato paste
- 1/2 cup water
- 2 teaspoons sugar
- 1 teaspoon dried basil
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
For the Ricotta Layer:
- 3 cups ricotta cheese
- 1 cup grated Parmesan
- 2 eggs
- 1/4 cup fresh parsley (chopped)
- Salt
You will also need:
- 12 lasagna noodles (no-boil or cooked)
- 4 cups shredded mozzarella cheese
- Extra Parmesan for topping
Prepare the Meat Sauce
Brown the ground beef and Italian sausage in a large pot over medium heat. Break up the meat as it cooks. This takes 8 to 10 minutes. Drain excess fat.
Add the chopped onion and minced garlic. Sauté until soft, about 5 minutes. Stir in crushed tomatoes, tomato sauce, tomato paste, water, sugar, basil, Italian seasoning, salt, and pepper. Bring to a simmer. Cook uncovered for 45 minutes. Stir occasionally. The sauce thickens as it reduces. Taste and adjust seasoning.
Make the Ricotta Mixture
While the sauce simmers, make the ricotta mixture. In a bowl, combine ricotta, Parmesan, eggs, parsley, and a pinch of salt. Mix until smooth. Set aside.
Prepare Lasagna Noodles
If using no-boil noodles, skip this step. For regular noodles, boil them in salted water until al dente. About 8 minutes. Drain and rinse with cold water. Lay them flat to prevent sticking.
Assemble the Lasagna
Preheat your oven to 375°F (190°C). Assemble the lasagna in a greased 9×13-inch dish. Spread 1 cup meat sauce on the bottom. Layer 4 noodles over the sauce. They may overlap slightly.
Add half the ricotta mixture in dollops. Spread evenly. Sprinkle 1 1/2 cups mozzarella. Pour 1 1/2 cups meat sauce on top.
Repeat the layers. Start with 4 noodles, then remaining ricotta, 1 1/2 cups mozzarella, and 1 1/2 cups sauce.
Top with the final 4 noodles. Spread remaining meat sauce. Cover with 1 cup mozzarella and a generous sprinkle of Parmesan.
Cover the dish tightly with aluminum foil. This prevents drying out. Bake for 25 minutes. Remove foil. Bake another 25 to 30 minutes until bubbly and golden. The cheese browns nicely.
Let the lasagna rest for 15 to 20 minutes before cutting. This sets the layers. Serve with garlic bread and salad.
Tips for Success
- Use high-quality ingredients. Fresh herbs elevate the flavor. San Marzano tomatoes make the sauce richer.
- No-boil noodles save time. They absorb moisture from the sauce during baking.
- Make sauce ahead. It tastes better after a day. Refrigerate up to 3 days or freeze for 3 months.
- Vegetarian option: Swap meat for mushrooms, spinach, and zucchini. Use the same method.
- Avoid soggy lasagna. Don’t overload on ricotta. Let it rest to firm up.
- Cheese melts best at room temperature. Shred your own for better texture.
Common Mistakes to Avoid
- Overcooking noodles makes them mushy. Follow package instructions.
- Skipping the foil leads to dry edges. Always cover initially.
- Too much sauce drowns the dish. Stick to the recipe ratios.
- Not resting causes slices to fall apart. Patience pays off.
- Using low-fat cheese can make it watery. Full-fat works best.
Variations to Try
- Seafood lasagna: Use shrimp and crab with white sauce.
- Mexican lasagna: Layer tortillas with beef, beans, salsa, and cheddar.
- Butternut squash lasagna: Roast squash for a sweet, veggie twist.
- Pesto lasagna: Mix pesto into ricotta for herby freshness.
Short on time? Use jarred sauce and frozen spinach.
Each variation keeps the oven-bake method. Adjust bake time if needed.
