  • Creamy and Cheesy: The creamy béchamel sauce and melted cheese create a luscious and indulgent texture.

  • Make-Ahead Friendly: You can assemble this lasagna ahead of time and bake it when you're ready to serve, making it perfect for entertaining.

Ingredients:

For the Spinach & Mushroom Filling:

  • 1 tablespoon olive oil
  • 1 lb mushrooms, sliced
  • 10 oz frozen spinach, thawed and squeezed dry
  • 1 (15 oz) container ricotta cheese
  • ½ cup grated Parmesan cheese
  • ½ cup shredded mozzarella cheese, divided
  • 1 egg, lightly beaten
  • 2 cloves garlic, minced
  • ½ teaspoon dried oregano
  • Salt and pepper to taste

For the Lasagna:

  • 9 lasagna noodles (no-boil recommended)
  • 24 oz marinara sauce
  • 8 oz fresh mozzarella cheese, sliced

Directions:

  • Step 1: Sauté Mushrooms:
    Heat the benefits of olive oil in a large skillet over medium heat. Add the sliced mushrooms and cook until softened and browned, about 5-7 minutes.

  • Step 2: Prepare Spinach:
    While the mushrooms are cooking, ensure your spinach is thoroughly thawed and squeezed dry to remove excess moisture. This is crucial for preventing a watery lasagna.

  • Step 3: Combine Filling Ingredients:
    In a large bowl, combine the ricotta cheese, Parmesan cheese, half of the shredded mozzarella cheese, the beaten egg, minced health benefits of garlic, dried oregano, salt, and pepper.

  • Add the sautéed mushrooms and the squeezed-dry spinach to the ricotta mixture. Stir well to combine all the ingredients for the creamy filling.

  • Step 4: Assemble the Lasagna:
    Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish. Spread a thin layer of marinara sauce on the bottom of the dish.

  • Step 5: Layer the Lasagna:
    Begin layering the lasagna. Place three no-boil lasagna noodles (or pre-boiled noodles if using regular lasagna noodles) over the sauce.

  • Spread half of the spinach and mushroom filling over the noodles.

  • Top with one-third of the sliced fresh mozzarella cheese. Repeat these layers (noodles, filling, mozzarella) two more times.

  • Step 6: Top with Sauce and Cheese:
    Pour the remaining marinara sauce over the top layer of noodles, ensuring it is evenly distributed. Sprinkle the remaining shredded mozzarella cheese over the sauce.

  • Step 7: Bake:
    Cover the baking dish tightly with aluminium foil. Bake for 30 minutes.

  • Remove the foil and bake for another 15-20 minutes, or until the lasagna is bubbly and the cheese is melted and golden brown.

  • Step 8: Rest:
    Let the lasagna rest for at least 10 minutes before cutting and serving. This allows the layers to be set and makes it easier to serve.

Serving and Storage:

  • Serving: creamy spinach & Mushroom Lasagna is best served warm, shortly after baking, when the cheese is melted and gooey and the layers are perfectly set.

  • Storage: Leftover lasagna can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven.

Tips for Success:

  • Squeeze the Spinach Dry: Thoroughly squeezing the spinach dry is crucial for preventing a watery lasagna.

  • Use No-Boil Noodles: No-boil lasagna noodles make this recipe even easier. If you use regular lasagna noodles, be sure to cook them al dente before assembling the lasagna.

  • Don't Overfill: Don't overfill the layers, as this can make the lasagna difficult to cut and serve.

  • Rest Before Serving: Allowing the lasagna to rest for at least 10 minutes before serving is essential for it to set properly.

Variations:

  • Add Vegetables: Add other vegetables, such as bell peppers, zucchini, or carrots, to the spinach and mushroom filling.

  • Spicy Lasagna: Add a pinch of red pepper flakes or a dash of hot sauce to the filling for a spicy kick.

  • Different Cheese: Use different cheeses, such as provolone or Gruyere, instead of mozzarella or Parmesan.

  • White Sauce Lasagna: Use a creamy white sauce instead of marinara sauce.

FAQ:

Can I use frozen spinach?

Yes, you can use frozen spinach. Make sure it is fully thawed and squeezed dry before adding it to the filling.

Can I make this ahead of time?

Yes, you can assemble the lasagna ahead of time and store it in the refrigerator, unbaked, for up to 24 hours. Add a few extra minutes to the baking time if baking from cold.

How do I know when the lasagna is cooked through?

The lasagna is cooked through when it is bubbly and the cheese is melted and golden brown.

Can I use a baking dish of a different size?

You can use a different size baking dish, but you may need to adjust the baking time.

What if my lasagna is too watery?

Make sure you have squeezed the spinach dry and that you haven't added too much sauce. You can also let the lasagna rest for a longer period of time before serving.

This Creamy Spinach & Mushroom Lasagna is a delicious, easy, and satisfying vegetarian meal that's perfect for any occasion.

The combination of creamy filling, tender pasta, and melted cheese is simply irresistible.

Ingredients
  

  • 1 tablespoon olive oil

Top with a final layer of noodles and the remaining marinara sauce. Sprinkle with the remaining mozzarella cheese.

  • Let rest: Let the lasagna rest for 10-15 minutes before cutting and serving. This will help it to set and make it easier to serve.

About Sana Umer

I'm Sana Umer — the home cook behind every recipe on For Foodie Friends. I'm a Pakistani-American mom of two based in the US, and I've been cooking seriously for about a decade now, mostly because feeding a family every day is the fastest way to learn how to actually cook.

I'm completely self-taught. I learned by watching my mother in Pakistan, by burning a lot of food in my early years, and by paying attention to which recipes worked and which ones needed fixing. I don't specialize in just one cuisine — I cook the Pakistani dishes I grew up with, the American desserts my kids request, weeknight dinners, holiday roasts, and everything in between.

Every recipe is personally tested in my own kitchen, every word is written by me, and every photo is taken of food I actually made.

Hi, I'm Sana Umer — the home cook, recipe tester, and writer behind For Foodie Friends.

I'm a Pakistani-American mom based in the US. I learned to cook in two kitchens — my mother's in Pakistan, where I grew up watching whole spices bloom in oil, and my own kitchen now, where I cook for my husband and kids.

Every recipe on this site has been tested in my own kitchen, often more times than I'd like to admit, before it ever made it here. I cook a little bit of everything: the Pakistani comfort food I grew up with, the American desserts my kids beg for, weeknight dinners that need to come together fast, and the holiday spreads that take all day.

If a recipe is on this site, it earned its place. No ghostwriters, no AI shortcuts, no copy-paste from somewhere else — just real recipes from a real kitchen, written to actually work the first time you make them.

Welcome to my corner of the internet.

— Sana
