Perfect Spinach Lasagna

Instructions

1. Step 1

   Gather the ingredients.

2. Step 2

   Bring a large pot of salted water to a boil. Cook lasagna noodles according to package instructions.

3. Step 3

   Preheat the oven to 350 F. Lightly grease a 9 x 13-inch baking dish or lasagna pan .

4. Step 4

   In a medium bowl, beat the egg. Add the ricotta cheese, half of the drained spinach, 1/2 cup of the grated Parmesan cheese, garlic powder, and salt. Mix to blend well.

5. Step 5

   In a separate large bowl, mix the remaining half of the drained spinach with the marinara sauce.

6. Step 6

   Spread about 1 cup of the marinara-spinach mixture over the bottom of the baking dish, just enough to coat the bottom.

7. Step 7

   Top with a layer of noodles. A 9x13-inch pan should fit 3 regular lasagna noodles lengthwise, but you can trim and tuck your noodles into the pan as needed depending on their size. Some overlap is ok.

8. Step 8

   Top the noodle layer with about 1 cup of the marinara-spinach mixture and spread evenly over the noodles.

9. Step 9

   With a small spoon, put about a third of the ricotta mixture over the sauce layer, spacing evenly in small dollops, then sprinkle with about a quarter of the mozzarella cheese.

10. Step 10

    Repeat with two more layers of the noodles, sauce, ricotta mixture, and mozzarella.

11. Step 11

    Top with another layer of noodles, the rest of the sauce, shredded mozzarella, and the remaining 1/2 cup of grated Parmesan cheese. 

12. Step 12

    Grease a sheet of foil large enough to fit over the lasagna. Cover the lasagna tightly with the foil, greased side down. If your baking pan is very full, place a foil-lined baking sheet on a lower rack to catch spills. 

13. Step 13

    Bake the lasagna for about 45 minutes, or until very hot and you can see it is beginning to bubble.

14. Step 14

    Remove the foil and bake for 20 to 30 minutes longer, until very hot and the cheese has browned to your liking.
