Ingredients

1 pound (450g) dry lasagna noodles
1 tablespoon salt (for boiling water)
3 tablespoons olive oil
1 large onion, finely chopped
4 cloves garlic, minced
2 pounds (900g) ground beef or Italian sausage
24 ounces (680g) marinara or tomato sauce
1 teaspoon dried oregano
1 teaspoon dried basil
1/2 teaspoon red pepper flakes (optional)
Salt and freshly ground black pepper to taste
15 ounces (425g) ricotta cheese

16 ounces (450g) shredded mozzarella cheese

1 cup (100g) grated Parmesan cheese

2 large eggs

1/4 cup chopped fresh parsley (optional)

Instructions

Preheat your oven to 375°F (190°C). Grease a 10×15-inch (or similarly large) baking dish with butter or non-stick spray.
Bring a large pot of water to a boil. Add 1 tablespoon of salt and cook the lasagna noodles according to package instructions until al dente, about 8-10 minutes. Drain and set aside.

In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook until translucent, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
Add the ground beef or sausage to the skillet. Cook, breaking apart the meat with a spoon, until browned and cooked through, about 8 minutes. Drain excess fat if necessary.
Stir in the marinara sauce, oregano, basil, red pepper flakes (if using), salt, and pepper. Reduce heat to low and simmer for 10 minutes to allow flavors to meld.

Meanwhile, in a medium bowl, combine ricotta cheese, eggs, chopped parsley (if using), a pinch of salt, and half of the grated Parmesan cheese. Mix until smooth.
To assemble the lasagna, spread a thin layer of meat sauce on the bottom of the prepared dish. Layer evenly with lasagna noodles, then spread half of the ricotta mixture over the noodles. Sprinkle with a third of the shredded mozzarella.
Repeat the layering: sauce, noodles, ricotta, mozzarella, until all ingredients are used, finishing with a layer of sauce topped with remaining mozzarella and Parmesan cheese.

Cover the dish tightly with aluminum foil. Bake in the preheated oven for 40 minutes. Remove the foil and bake for an additional 10 minutes, until bubbly and golden on top.
Let the lasagna rest for at least 15 minutes before slicing. This helps it set and makes serving easier.

Tips

Substitutions: Use ground turkey or plant-based meat for a lighter or vegetarian version. Whole wheat noodles can add fiber.

Cheese options: For a richer flavor, add a layer of sliced mozzarella or provolone cheese on top before baking.
Prevent sticking: Be sure to oil or butter the baking dish and use enough sauce to keep the noodles moist.
Storage tips: If preparing ahead, assemble the lasagna, cover tightly, and refrigerate for up to 24 hours before baking.

Serving Suggestions

Serve the lasagna hot, paired with a simple green salad dressed with vinaigrette and crusty garlic bread for a complete meal. A glass of red wine, such as Chianti or Sangiovese, complements the rich flavors beautifully.

Variations

Vegetarian: Replace meat with sautéed vegetables like zucchini, spinach, mushrooms, and bell peppers. Use a hearty marinara or tomato sauce to compensate for the missing meat.
White lasagna: Swap the marinara for a béchamel or Alfredo sauce, and include cooked spinach, mushrooms, or chicken for added flavor.

Vegan: Use plant-based cheese, vegan sausage or lentils, and a tomato-based sauce. Be sure to choose vegan noodles if needed.

Storage and Reheating

Leftover lasagna can be stored in an airtight container in the refrigerator for up to 4 days. To reheat, cover slices with foil and bake at 350°F (175°C) for about 20-25 minutes, or until heated through. You can also microwave individual slices for 2-3 minutes, depending on your microwave’s power, but reheating in the oven preserves the best texture.

Frequently Asked Questions

Can I prepare this lasagna in advance?

Yes, you can assemble the lasagna up to 24 hours ahead of baking. Cover tightly with plastic wrap or foil and refrigerate. Bake directly from the fridge, adding an extra 10-15 minutes to the baking time if needed.

Can I freeze leftovers?

Absolutely. Let the lasagna cool completely, then wrap tightly with plastic wrap and foil. Freeze for up to 3 months. To reheat, thaw overnight in the refrigerator and bake at 350°F (175°C) for 30-40 minutes until hot and bubbly.

What if I don’t have a 10×15-inch dish?

You can use a slightly smaller or larger dish, but the cooking time may vary. Ensure the lasagna is covered with foil and check for doneness; it should be bubbly around the edges and heated through.

How do I prevent the top from burning?

Cover the lasagna with foil during most of the baking process. Remove the foil during the last 10 minutes to allow the cheese to brown. Keep an eye on it to prevent over-browning.

Can I make this gluten-free?

Yes, substitute regular lasagna noodles with gluten-free pasta. Ensure all ingredients, especially sauces and cheeses, are gluten-free to avoid cross-contamination.

What’s the best way to serve lasagna?

Allow the lasagna to rest for at least 15 minutes after baking to help it set. Use a sharp knife to cut clean slices. Serve with your favorite sides for a complete meal.
