Introduction

This Vegetarian Lasagna is a comforting and cheesy dish perfect for family dinners or special occasions. Layers of creamy ricotta, mozzarella, and marinara sauce combine with tender no-boil noodles for an easy, satisfying meal.

A white baking dish shows a partially eaten lasagna with three visible layers: a bottom layer of bright red tomato sauce, a middle layer of creamy white ricotta cheese that looks soft and thick, and a top layer of melted pale yellow mozzarella cheese with some light golden spots from baking. The edges reveal the texture of pasta sheets soaked in sauce, and the top is sprinkled with small, fresh green parsley pieces. The sauce and cheese have slightly spilled over the dish sides, creating a rustic and hearty look, set on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

3 cups ricotta cheese
3 cups shredded mozzarella cheese, divided

1 cup freshly grated Parmesan cheese, divided
2 tablespoons Italian seasoning

1 egg, beaten
Kosher salt

Freshly ground black pepper
Cooking spray
1 cup marinara sauce (from a 32-oz. jar)

1 box (16 oz.) no-boil lasagna noodles
Thinly sliced fresh basil, for garnish
Freshly chopped parsley, for garnish

Instructions

Step 1: Preheat the oven to 350°F. In a large bowl, combine ricotta, 2 cups mozzarella, 1 cup Parmesan, Italian seasoning, and the beaten egg. Season with ½ teaspoon salt and 6 to 8 grinds of fresh black pepper. Stir until well mixed.
Step 2: Grease a 9″x13″ baking dish with cooking spray. Spread ½ cup marinara sauce evenly over the bottom. Add a layer of no-boil noodles, then spoon ¾ cup marinara sauce and ¾ cup of the ricotta mixture over the noodles. Repeat layering 4 to 6 times depending on your dish depth, finishing with a layer of sauce. Sprinkle the remaining 1 cup mozzarella on top.
Step 3: Spray a piece of foil with cooking spray on one side and cover the lasagna with the sprayed side down. Bake for 35 minutes. Remove the foil and increase the oven temperature to 400°F. Continue baking until the cheese is melted and bubbly, about 10 to 15 minutes more. Let the lasagna rest for 15 minutes before serving.

Step 4: Garnish with thinly sliced basil and freshly chopped parsley, then serve warm.

Tips & Variations

For extra flavor, add sautéed vegetables like spinach, mushrooms, or zucchini between the layers.
Use fresh mozzarella for a creamier texture, but reduce the shredded mozzarella accordingly.

If you prefer, swap marinara for your favorite tomato basil sauce for a different flavor.
Letting the lasagna rest after baking helps it set, making it easier to cut and serve.

Storage

Store leftover lasagna in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm in the oven at 350°F until heated through. This dish also freezes well; wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
