Prep Time: 20 minutes

Cook Time: 45 minutes

Servings: 6–8

  • 1. Preheat the oven. Preheat your oven to 375°F (190°C).
  • 2. Cook the noodles. Boil the lasagna noodles according to package instructions. Drain and set aside.
  • 3. Sauté onions and garlic. Heat olive oil in a pan and sauté the chopped onion and garlic until soft and fragrant, about 3–5 minutes.
  • 4. Prepare the spinach filling. Add the chopped spinach to the pan with onions and garlic. Cook for 3–4 minutes until wilted. Remove from heat. Mix in the ricotta, 1 cup of mozzarella, parmesan cheese, salt, and pepper.
  • 5. Assemble the lasagna. In a baking dish, spread a layer of marinara sauce. Place 3 lasagna noodles over the sauce, then add a layer of the spinach-ricotta mixture. Repeat the layers until all ingredients are used, finishing with a layer of marinara sauce and mozzarella cheese on top.
  • 6. Bake. Cover with foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15 minutes until the cheese is melted and golden.
  • 7. Serve. Let the lasagna cool for 10 minutes before slicing. Serve with a side salad or garlic bread.

Tips for Perfect Spinach Lasagna

  • Don’t overcook the noodles: They will cook further in the oven.
  • Use fresh spinach: Fresh spinach adds more flavor and texture.
  • Let it cool before slicing: This allows the lasagna to set and makes it easier to cut clean slices.

Variations & Substitutions

  • Add ricotta alternatives: Substitute ricotta with cottage cheese or tofu for a different texture.
  • Make it gluten-free: Use gluten-free lasagna noodles.
  • Try different greens: Kale or swiss chard would also work well in place of spinach.

Storing & Reheating

  • Fridge: Store leftovers in an airtight container for up to 4 days.
  • Reheat: Reheat in the oven at 350°F for 15 minutes or until hot.
  • Freezer: Freeze baked lasagna for up to 3 months. Reheat in the oven until bubbly.
