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.
