The only time we'd mess with something as perfect as lasagna is to make it gluten-free! This classic Gluten-Free Italian Sausage Ground Beef Lasagna is great for feeding a crowd or anytime you need a hearty comfort meal.
Preheat oven to 400°F (204°C). In a large, deep skillet, brown the Italian sausage and ground beef. Drain excess fat, then add the onion and tomato paste.
Add crushed tomatoes, tomato sauce, brown sugar, parsley, basil, salt, and pepper. Bring to a boil, then reduce heat and simmer for 5–7 minutes.
In a bowl, combine ricotta cheese, egg, and Parmesan cheese.
Lightly grease a large baking dish. Begin layering with about 2 cups meat sauce, 1 1/4 cups cheese mixture, 3 mozzarella slices, and 3 Lasagna Sheets. There is no need to boil the Lasagna Sheets first.
Repeat the layers three times, then top the final layer of Lasagna Sheets with the remaining sauce and cheese.
Cover with foil and bake for 20–30 minutes. Remove the foil and bake for an additional 10–15 minutes, or until the cheese is bubbly.
