Instructions:

1. Preheat the oven: Let’s get started! First, preheat the oven to 375°F (190°C) so it’s ready when you finish assembling the lasagna.
2. Sauté the onion and garlic: Next, heat 2 tablespoons (30 ml) of olive oil in a large skillet over medium heat. Add the chopped onion and finely chopped garlic, cooking until translucent and fragrant, about 3-4 minutes.
3. Cook the ground beef: Now, add 1 pound (450 g) of ground beef to the skillet. Season with salt and pepper to taste, and cook over medium-high heat, gently breaking up the meat with a wooden spoon until well browned, about 7-8 minutes.
4. Add sauce and seasonings: Stir in 2 cups (480 ml) of pasta tomato sauce and 1 teaspoon (5 g) of dried oregano. Mix well and simmer on low heat for 10 minutes, stirring occasionally.
5. Mix ricotta and egg: Meanwhile, in a medium bowl, combine 1 cup (240 ml) of ricotta cheese with 1 large egg until fully blended.
6. Assemble the first layer: In a rectangular baking dish (approximately 23x33 cm), spread a thin layer of the meat sauce on the bottom to prevent the noodles from sticking. You can also grease with a bit of oil or butter for easier cleanup.
7. Layer the lasagna: Now it’s time to layer! Place a layer of lasagna noodles (4-5 sheets), followed by a layer of the ricotta mixture, then meat sauce, and a sprinkle of shredded mozzarella (about 1/3 cup / 65 g). Spread everything evenly.
8. Repeat the layers: Repeat the layering process—noodles, ricotta, sauce, and mozzarella—until you run out of ingredients. The final layer should be meat sauce topped with mozzarella cheese, sprinkled with 1/2 cup (50 g) grated Parmesan cheese on top.
9. Cover and bake: Cover the dish with aluminum foil and bake for 30 minutes in the preheated oven.
10. Brown the lasagna: Carefully remove the foil and bake for an additional 15 minutes or until the cheese is golden and bubbly.
11. Let it rest: Done! Remove the lasagna from the oven and let it rest for 10 minutes before cutting and serving so the layers set properly.

Preparation Tips:

• Season the meat well while cooking to enhance flavor — this is important for the final result.
• Don’t overload the layers; this way the lasagna will cook evenly and have a good texture.
• It’s important to cover the baking dish with foil for most of the baking time to prevent the cheese from burning.
• Let the lasagna rest after taking it out of the oven so the layers settle, it’s easier to cut, and no one burns their mouth while eating.
• Use an appropriately sized baking dish so the layers aren’t too thick.

Side Suggestions:

• Pair your lasagna with a fresh arugula salad dressed with lemon and olive oil to balance the meal.
• Don’t forget crispy garlic bread to enjoy with the lasagna sauce.
• A glass of smooth red wine, like Chianti or Merlot, is a perfect pairing choice.
• Steamed or roasted vegetables like broccoli or asparagus also make a great side.
• For dessert, something light like fresh fruit or homemade gelatin to round off the meal.

Recipe Variations:

• Vegetarian lasagna: For our vegetarian friends, substitute the meat with sautéed mushrooms, spinach, and eggplant.
• Chicken and spinach lasagna: A lighter version, use shredded chicken instead of beef and add fresh spinach.
• Seafood lasagna: A delicious option! Use cooked shrimp and white fish with béchamel sauce instead of tomato sauce.
• Gluten-free lasagna: If you’re concerned about gluten, use gluten-free pasta sheets and make sure cheeses and sauces are compatible.
• Zucchini lasagna: A very light option! Replace the pasta sheets with thin zucchini slices for a low-carb alternative.
