Meat And Eggplant Sauce Lasagna - cooking recipe

Ingredients

Sauce:
1 tablespoon olive oil, or more as needed
1/2 large white onion, diced
5 cloves garlic, finely chopped
1 pound lean ground beef
salt and ground black pepper to taste
2 (28 ounce) cans crushed tomatoes
1 eggplant, peeled and diced
2 zucchini, peeled and diced
2 cups sliced fresh mushrooms
1 cup diced carrots
3/4 cup tomato puree
2 tablespoons salt
2 tablespoons dried basil
1 tablespoon ground black pepper
1 tablespoon dried oregano
1 bay leaf
Lasagna:
1 (16 ounce) package lasagna noodles
4 cups ricotta cheese
1 egg
4 cups shredded mozzarella cheese, or more to taste
1/2 cup grated Parmesan cheese

Preparation

Heat oil in a large pot over medium heat. Add onion and garlic; cook and stir until onions start turning clear, 5 to 10 minutes. Add ground beef; season with salt and pepper. Cook and stir until browned and crumbly, 5 to 7 minutes. Add crushed tomatoes. Fill the empty tomato can with water and pour into the sauce.
Stir eggplant, zucchini, mushrooms, carrots, tomato puree, 2 tablespoons salt, basil, black pepper, oregano, and bay leaf into the sauce. Bring to a boil; reduce heat to medium-low. Cook, stirring occasionally, until flavors are well blended, about 1 hour. Remove and discard bay leaf.
Bring a large pot of lightly salted water to a boil. Cook lasagna noodles in the boiling water, stirring occasionally until tender yet firm to the bite, about 8 minutes. Drain and lay the noodles out on paper towels to dry; remove and discard any broken pieces.
Combine ricotta and egg in a bowl; season with salt and pepper and whisk thoroughly.
Preheat the oven to 375 degrees F (190 degrees C).
Coat the bottom of a large baking pan with the sauce. Layer noodles, ricotta mixture, sauce, mozzarella cheese, and a sprinkle of Parmesan cheese on top. Repeat layering until all used up. Cover the pan with aluminum foil.
Bake in the preheated oven until bubbling furiously, 30 to 35 minutes. Uncover pan and increase oven temperature to 400 degrees F (200 degrees C). Continue baking until top is golden brown, 10 to 15 minutes more. Let lasagna sit for 10 to 15 minutes before serving.
