Method
- Preheat oven to 400°F (200°C). This temperature creates perfectly crispy edges for your ricotta lasagna.
- Make the ricotta mixture: Beat the egg in a medium bowl with salt and pepper. Add ricotta cheese and chopped parsley. Mix everything until smooth and creamy.
- First layer: Spread ½ cup of marinara sauce across the bottom of your 9×13-inch baking dish. Place 4 no-boil lasagna noodles on top, slightly overlapping. Spread about 1 cup of ricotta mixture over the noodles, reaching to the edges. Sprinkle 1 cup of mozzarella over the ricotta.
- Second layer: Add 4 more noodles over the cheese. Spread ½ cup of marinara sauce over the noodles. Sprinkle 1 cup of grated Parmesan evenly over the sauce.
- Third layer: Place 4 more noodles over the sauce and Parmesan. Spread the remaining ricotta mixture over these noodles. Top with 1 cup of mozzarella cheese.
- Final layer: Add the final 4 noodles. Pour the remaining 1 cup of sauce over the top, spreading to cover completely. Finish with the remaining ½ cup each of mozzarella and Parmesan cheeses.
- Bake covered: Cover the entire dish with aluminum foil. Bake for 30 minutes at 400°F.
- Bake uncovered: Remove the foil and lower oven temperature to 375°F (190°C). Continue baking for 15 more minutes until cheese is golden brown and edges are crispy.
- Rest before serving: Let the lasagna cool in the pan for 10-15 minutes before cutting. This helps everything set up for clean, beautiful slices.
Notes
Make-ahead tips: Assemble unbaked lasagna up to 24 hours before baking. Cover and refrigerate, then bake as directed.
Freezing instructions: Unbaked lasagna freezes for up to 1 month. Thaw overnight in refrigerator before baking.
Storage: Baked lasagna keeps 4 days in refrigerator or 2 months in freezer.
Cheese tip: You'll need about 1¼ pounds of ricotta total, usually requiring 2 containers. Use leftover ricotta for lemon ricotta cake!
Perfect texture: Use low-moisture mozzarella to prevent watery lasagna. Those crispy edges are a sign of success!
