Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 12 lasagna sheets
• 3 cups cooked spinach, drained well and chopped
• 2 cups ricotta cheese
• 2 cups mozzarella cheese, shredded
• 1/2 cup Parmesan cheese, grated
• 2 cups tomato sauce
• 1 large egg
• 1 garlic clove, minced
• 1 tablespoon olive oil
• 1 teaspoon salt
• 1/2 teaspoon black pepper

Optional additions for extra flavor:

• 1 teaspoon Italian seasoning
• 1/4 teaspoon red pepper flakes
• Fresh basil for garnish

Directions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a little olive oil.
2. Cook the spinach if using fresh spinach. Once cooked, drain it thoroughly to remove excess moisture. Chop the spinach into smaller pieces for easier layering.
3. In a large mixing bowl, combine the ricotta cheese, egg, cooked spinach, minced garlic, salt, and black pepper. Stir until the mixture is smooth and evenly blended.
4. Spread a thin layer of tomato sauce across the bottom of the prepared baking dish. This prevents the lasagna sheets from sticking.
5. Arrange a layer of lasagna sheets over the sauce. Depending on the size of your dish, you may need to slightly overlap the pasta sheets.
6. Spread part of the spinach and ricotta mixture over the pasta layer. Add a spoonful of tomato sauce and sprinkle mozzarella cheese on top.
7. Repeat the layers: pasta sheets, ricotta filling, sauce, and mozzarella cheese until all ingredients are used. Finish with a final layer of pasta sauce topped generously with mozzarella and Parmesan cheese.
8. Cover the baking dish loosely with foil and bake for 30 minutes. Remove the foil and continue baking for another 5 to 10 minutes until the cheese is melted, golden, and bubbly.
9. Let the lasagna rest for at least 10 minutes before slicing. This helps the layers hold together and makes serving easier.
10. Garnish with fresh basil if desired and serve warm.
