✓ Heat 2 tablespoons olive oil in a large pot over medium heat.

✓ Add finely chopped onion and garlic, cooking until softened (about 5 minutes).

✓ Add 1 pound ground beef or Italian sausage; cook until fully browned (about 7-8 minutes), breaking up any clumps with a wooden spoon.

✓ Stir in 2 teaspoons of Italian seasoning and cook for another minute.

✓ In a large bowl, mix 2 cups ricotta cheese with 1 egg until well combined.

✓ Gradually stir in 1/2 cup grated Parmesan cheese to create a smooth mixture.

✓ Bring a large pot of salted water to a boil; add lasagna noodles, cooking according to package instructions (about 7-8 minutes).

✓ Preheat your oven to 375°F (190°C). Drain the noodles and place them between sheets of parchment paper or on a clean kitchen towel to prevent sticking.

✓ Spread about 1 cup tomato sauce in the bottom of a 9×13-inch baking dish.

✓ Add a layer of cooked lasagna noodles (about 3-4) over the sauce, breaking them slightly with your fingers if needed to fit.

✓ Spoon half of the meat sauce over the noodles and spread evenly.

✓ Spread about half of the ricotta mixture on top of the meat sauce.

✓ Sprinkle a layer of shredded mozzarella cheese (about 1 cup).

✓ Repeat this process with another layer of noodles, remaining sauces, and cheeses.

✓ Cover the final layer with noodles and pour any leftover sauce over them.

✓ Top with the remaining shredded mozzarella cheese.

✓ Bake in preheated oven for about 25-30 minutes or until the top is golden brown and bubbly.

✓ Remove from oven and let sit for at least 10 minutes before slicing to allow it to set up slightly.
