Ingredients

• 2 teaspoons salt
• 1 pinch white sugar
• 1 (16 ounce) container sour cream
• 1 clove garlic, minced
• 1 (8 ounce) can tomato sauce
• 1 tablespoon dried parsley
• 1 (8 ounce) package lasagna noodles
• 1 (28 ounce) can diced tomatoes
• 3 large eggs, lightly beaten
• 2 (12 ounce) packages shredded mozzarella cheese, divided
• 0.25 teaspoon ground black pepper
• 0.5 teaspoon dried basil
• 0.5 teaspoon dried oregano
• 0.75 cup grated Parmesan cheese
• 0.5 pound ground beef
• 0.5 pound ground pork sausage
• 0.5 cup chopped pitted green olives

Recipe Instructions

Step 1

Preheat the oven to 375 degrees F (190 degrees C).

Step 2

Cook sausage, ground beef, and garlic in a large skillet over medium-high heat, stirring occasionally, until browned and crumbly, 5 to 7 minutes. Drain any excess grease.

Step 3

Stir in diced tomatoes, tomato sauce, parsley, basil, oregano, and sugar. Bring to a boil over high heat, then reduce the heat to medium-low and simmer, stirring occasionally, until thickened, about 30 minutes.

Step 4

When the sauce has simmered for about 15 minutes, bring a large pot of lightly salted water to a boil. Add lasagna noodles and cook, uncovered, stirring occasionally, until tender yet firm to the bite, about 8 minutes. Drain.

Step 5

Stir sour cream, 1/2 of the mozzarella, Parmesan, olives, eggs, salt, and pepper together in a bowl.

Step 6

Assemble the lasagna: Spread a thin layer of meat sauce evenly over the bottom of a 9x13-inch baking dish. Cover with 1/3 of the lasagna noodles, 1/3 of the remaining meat sauce, and 1/3 of the cheese mixture; repeat layers two more times with remaining noodles, sauce, and cheese mixture. Sprinkle remaining mozzarella evenly over top.

Step 7

Bake in the preheated oven until sauce is bubbly and the cheese is golden brown, about 30 minutes.
