Classic Spinach Ricotta Lasagna (Printer-friendly)

Comforting vegetarian lasagna with spinach, ricotta, and mozzarella in tangy tomato sauce.

# What You’ll Need:

→ Cheese & Dairy

01 - 2 cups ricotta cheese
02 - 2 cups shredded mozzarella cheese
03 - 1/2 cup grated Parmesan cheese
04 - 2 large eggs

→ Vegetables

05 - 12 oz fresh spinach
06 - 1 medium onion, finely chopped
07 - 3 cloves garlic, minced

→ Pantry

08 - 9-12 no-boil lasagna noodles
09 - 4 cups marinara sauce
10 - 2 tbsp olive oil
11 - 1/2 tsp dried oregano
12 - 1/2 tsp dried basil
13 - 1/2 tsp salt
14 - 1/4 tsp black pepper

# How to Make It:

01 - Preheat the oven to 375°F.
02 - Heat olive oil in a large skillet over medium heat. Add onion and cook until soft, about 4 minutes. Add garlic and sauté 1 minute more.
03 - Add spinach to the skillet. If using fresh, wilt for 2-3 minutes. If using thawed frozen spinach, cook until any excess moisture evaporates. Season with salt, pepper, oregano, and basil. Transfer to a bowl and let cool slightly.
04 - In a large mixing bowl, combine ricotta cheese, eggs, half the Parmesan, and a pinch of salt and pepper. Stir in the cooled spinach mixture.
05 - Spread 1 cup of marinara sauce over the bottom of a 9x13-inch baking dish.
06 - Layer 3-4 noodles over the sauce. Spread one-third of the ricotta-spinach mixture over noodles. Sprinkle with one-third of the mozzarella.
07 - Spoon 1 cup of marinara sauce over the cheese layer. Repeat layering (noodles, ricotta-spinach, mozzarella, sauce) two more times, finishing with noodles and remaining sauce. Top with remaining mozzarella and Parmesan.
08 - Cover the dish with foil and bake for 30 minutes.
09 - Remove foil and bake 15-20 minutes more, until the cheese is bubbling and golden.
10 - Let the lasagna rest for 10-15 minutes before slicing and serving.

# Expert Tips:

01 -
  • The ricotta-spinach filling stays incredibly creamy without any watery surprises
  • Leftovers actually taste better the next day, making weekday lunches feel special
02 -
  • Greasing your foil before covering the lasagna prevents the cheese from sticking and pulling off when you remove it
  • Letting the lasagna rest before cutting is the difference between neat slices and a messy slide onto the plate
03 -
  • Squeeze thawed frozen spinach in a clean towel until virtually no liquid remains
  • Use the back of a spoon to spread the ricotta mixture evenly so the noodles are fully covered
