Ingredients
Method
Prepare the Components
- Preheat oven to 375°F. Bring a large pot of salted water to boil for the pasta.
- Heat olive oil in a large saucepan over medium heat. Add diced onion and cook for 5-6 minutes until softened. Add minced garlic and cook 1 minute more until fragrant.
- Stir in tomato paste and cook for 1 minute. Add crushed tomatoes, tomato sauce, oregano, dried basil, sugar, salt, and red pepper flakes if using. Bring to a simmer, then reduce heat to low and cook for 20 minutes, stirring occasionally. Taste and adjust seasoning.
- Meanwhile, cook lasagna noodles according to package directions until just al dente (they'll finish cooking in the oven). Drain and lay flat on a clean kitchen towel to prevent sticking.
- In a large bowl, combine ricotta, beaten eggs, fresh basil, salt, and pepper. Mix well and set aside.
Assemble the Lasagna
- Spread 1 cup of marinara sauce in the bottom of a 9x13 inch baking dish.
- Layer 4-5 lasagna noodles over the sauce, overlapping slightly if needed to cover the bottom.
- Spread half of the ricotta mixture over the noodles, then sprinkle with 1/3 of the mozzarella and 1/4 cup Parmesan.
- Add another layer of noodles, then 1.5 cups of sauce, the remaining ricotta mixture, and another 1/3 of the mozzarella.
- Top with remaining noodles, remaining sauce, and the rest of the mozzarella and Parmesan cheese.
- Cover tightly with foil (tent it so it doesn't touch the cheese) and let rest at room temperature for 30 minutes.
Bake and Serve
- Bake covered for 45 minutes. Remove foil and bake 10-15 minutes more until cheese is golden and bubbly.
- Let cool for 15 minutes before cutting (this helps the layers hold together).
- Cut into squares and serve with extra Parmesan cheese and fresh basil if desired.
Notes
Lasagna can be assembled up to 24 hours ahead and refrigerated before baking (add 10-15 minutes to baking time if cooking from cold). Leftovers keep for 4 days refrigerated and reheat beautifully in the microwave or a 350°F oven. You can substitute part-skim ricotta and mozzarella to reduce calories without sacrificing much flavor.
