Ingredients:

- 1 medium onion, chopped (about 1 cup) (140g)
- 2 cloves garlic, minced (approx. 6g)
- 1 (28-ounce) can crushed tomatoes (794g)
- 1 (15-ounce) can tomato sauce (425g)
- 1 teaspoon dried oregano (5 ml)
- 1/2 teaspoon dried basil (2.5 ml)
- 1/4 teaspoon red pepper flakes (optional) (1 ml)
- 1/2 teaspoon sugar (2.5 ml)
- Salt and black pepper to taste
- 1 (30-ounce) container ricotta cheese (850g), whole milk or part-skim
- 1 large egg, lightly beaten
- 1/2 cup grated Parmesan cheese (50g)
- 1/4 cup chopped fresh parsley (approximately 5g)
- 1/4 teaspoon ground nutmeg (1ml)
- Salt and black pepper to taste
- 9 lasagna noodles, cooked according to package directions and drained
- 2 cups shredded mozzarella cheese (225g), divided
Instructions:
- Prepare the Tomato Sauce: Sauté onion and garlic in olive oil. Add crushed tomatoes, tomato sauce, oregano, basil, red pepper flakes (if using), sugar, salt, and pepper. Simmer for 15 minutes, stirring occasionally.
- Cook the Noodles: Cook the lasagna noodles according to package directions. Drain well.
- Make the Ricotta Filling: In a large bowl, combine ricotta cheese, egg, Parmesan cheese, parsley, nutmeg, salt, and pepper. Mix until well combined.
- Assemble the Casserole: Spread a thin layer of tomato sauce in the bottom of the baking dish.
- Layer the Casserole: Lay 3 lasagna noodles on the sauce. Spread half of the ricotta mixture evenly over the noodles. Sprinkle with 1/3 of the mozzarella cheese.
- Repeat Layers: Lay 3 more lasagna noodles, repeat with remaining ricotta mixture and 1/3 of the mozzarella cheese.
- Final Layer: Top with the last 3 lasagna noodles, remaining tomato sauce, and the remaining mozzarella cheese.
- Bake: Cover the baking dish with foil and bake in a preheated oven at 375°F (190°C) for 30 minutes.
- Uncover and Bake: Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.
- Rest: Let the casserole rest for 10 minutes before serving. This will help it to slice easier.
