Ingredients

1 pound (450g) ground beef or Italian sausage
1 medium onion, finely chopped
3 cloves garlic, minced
28 ounces (800g) canned crushed tomatoes
2 tablespoons tomato paste
1 teaspoon dried oregano
1 teaspoon dried basil
Salt and freshly ground black pepper to taste
12 no-boil or traditional lasagna noodles (about 9 oz)
15 ounces (425g) ricotta cheese or cottage cheese
2 large eggs
2 cups (200g) shredded mozzarella cheese
1/2 cup (50g) grated Parmesan cheese
2 tablespoons chopped fresh parsley (optional)
2 tablespoons olive oil

Instructions

Preheat the oven to 375°F (190°C). Grease a 12×18-inch baking dish with a little olive oil or non-stick spray to prevent sticking.
Prepare the meat sauce. In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and cook until translucent, about 5 minutes. Stir in the minced garlic and cook for another minute. Add the ground beef or sausage, breaking it apart with a spoon, and cook until browned and cooked through, about 8-10 minutes. Drain excess fat if necessary.

Add the tomatoes and seasonings. Stir in the crushed tomatoes, tomato paste, oregano, basil, salt, and pepper. Bring to a simmer, reduce heat to low, and cook uncovered for 15-20 minutes, stirring occasionally. Taste and adjust seasoning as needed.
Prepare the ricotta mixture. In a bowl, combine ricotta cheese, eggs, chopped parsley (if using), a pinch of salt, and pepper. Mix until smooth and set aside.
Assemble the lasagna. Spread a thin layer of meat sauce on the bottom of the prepared dish. Place a layer of noodles over the sauce, slightly overlapping. Spread half of the ricotta mixture over the noodles, then sprinkle with 1 cup of shredded mozzarella and a little Parmesan. Repeat with another layer of sauce, noodles, remaining ricotta, mozzarella, and Parmesan. Finish with a final layer of noodles topped with remaining meat sauce and mozzarella cheese.

Bake the lasagna. Cover the dish tightly with aluminum foil (to prevent cheese from burning). Bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden brown.
Rest and serve. Let the lasagna rest for at least 15 minutes before slicing. This helps it set and makes serving easier. Garnish with additional parsley if desired, then cut into generous 12×18-inch squares and serve hot.

Tips

Substitutions: Use ground turkey or chicken for a lighter version, or plant-based meat alternatives. For the cheese, part-skim ricotta or mozzarella can reduce fat content.

Storage: Cover and refrigerate leftovers for up to 4 days. For longer storage, freeze individual portions for up to 3 months. Wrap tightly to prevent freezer burn.
Common mistakes: Overcooking noodles can make them mushy; use no-boil noodles if preferred. Also, avoid overloading with cheese, which can cause it to become greasy or soggy.
Extra tips: To enhance flavor, add a splash of red wine to the sauce or a pinch of red pepper flakes for heat. Fresh herbs can also elevate the dish.

Serving Suggestions

Serve this hearty lasagna with a crisp green salad dressed with vinaigrette and a side of garlic bread or warm baguette slices. For a complete meal, add roasted vegetables or a simple antipasto platter. A glass of red wine such as Chianti or Sangiovese pairs beautifully with the rich flavors of the dish.

Variations

For a vegetarian version, substitute the meat with sautéed vegetables like zucchini, mushrooms, bell peppers, and spinach. Layered with the same cheese and sauce, it creates a delicious, meat-free alternative. You can also customize the cheese blend by adding ricotta mixed with spinach or herbs, or sprinkle with different cheeses like provolone or fontina for a different flavor profile.

Storage and Reheating

Leftover lasagna can be stored covered in the refrigerator for up to 4 days. To reheat, cover with foil and bake at 350°F (175°C) for about 20-25 minutes until heated through, or microwave individual portions for 2-3 minutes, checking and stirring as needed. For frozen lasagna, thaw overnight in the fridge before reheating, or bake directly from frozen, covered with foil, for about 45-50 minutes, then uncover and bake for an additional 10 minutes to crisp the cheese.

Frequently Asked Questions

Can I use no-boil noodles for this recipe?

Yes, no-boil noodles work well and save time. Just ensure you add enough sauce to keep the noodles moist during baking, as they absorb liquid as they cook.

How do I prevent the lasagna from becoming soggy?

Avoid overloading with excessive cheese or sauce, and let the lasagna rest for at least 15 minutes after baking. This helps the layers set and reduces sogginess.

Can I prepare this lasagna ahead of time?

Absolutely. Assemble the lasagna a day in advance, cover tightly, and refrigerate. Bake it straight from the fridge, adding an extra 10-15 minutes to the baking time as needed.

What if I don’t have Parmesan cheese?

You can omit Parmesan or substitute with Pecorino Romano or Grana Padano for similar salty, sharp flavors. Cheddar can also be used for a different taste.

Is this recipe suitable for freezing?

Yes, assembled and baked lasagna freezes well. Wrap tightly with plastic wrap and aluminum foil, then store for up to 3 months. Thaw overnight in the fridge before reheating or bake directly from frozen with added time.

How can I make this dish more spicy?

Add red pepper flakes to the sauce or sprinkle chopped jalapeños over the layers for extra heat. Adjust the amount to your preferred spice level.
