Ingredients

For the Lasagna

• 9–12 lasagna noodles
• 2 tablespoons olive oil
• 2 cups sliced mushrooms
• 4 cups fresh baby spinach
• 1 small yellow onion, finely diced
• 4 cloves garlic, minced
• 3 cups marinara sauce
• 2 cups shredded mozzarella cheese
• ½ cup freshly grated Parmesan cheese
• 2 tablespoons fresh parsley, chopped

For the Cottage Cheese Filling

• 2 cups cottage cheese
• 1 large egg
• ½ cup grated Parmesan cheese
• 1 teaspoon Italian seasoning
• ½ teaspoon dried oregano
• ½ teaspoon garlic powder
• ½ teaspoon salt
• ½ teaspoon black pepper
• ¼ teaspoon red pepper flakes, optional

Optional Additions

• ½ cup chopped roasted red peppers
• ½ cup finely chopped zucchini
• ½ cup shredded mozzarella for extra topping
• Fresh basil
• A pinch of nutmeg
• 1 tablespoon fresh lemon zest

Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish with olive oil or cooking spray.

Set the dish aside.

2. Cook the Lasagna Noodles

Bring a large pot of salted water to a boil.

Cook the lasagna noodles according to the package directions until just tender.

Avoid overcooking them because they will continue cooking in the oven.

Drain the noodles and arrange them separately on a baking sheet or lightly oiled plate to prevent them from sticking together.

If using oven-ready lasagna noodles, you can skip this step and use them according to the package directions.

3. Prepare the Mushroom and Spinach Mixture

Heat olive oil in a large skillet over medium heat.

Add the diced onion and cook for approximately 3–4 minutes, until softened.

Add the sliced mushrooms.

Cook for 6–8 minutes, stirring occasionally, until the mushrooms become golden and most of their moisture has evaporated.

This step is important because mushrooms contain a lot of water. Cooking them properly helps prevent a watery lasagna.

Add the minced garlic and cook for another 30–60 seconds.

Add the fresh spinach.

Cook for approximately 2 minutes, stirring until the spinach wilts.

Remove the skillet from the heat.

Allow the mixture to cool slightly.

4. Make the Cottage Cheese Filling

In a large bowl, combine:

• Cottage cheese
• Egg
• Parmesan
• Italian seasoning
• Oregano
• Garlic powder
• Salt
• Black pepper
• Red pepper flakes, if using

Stir until everything is evenly combined.

For an especially smooth filling, blend the cottage cheese in a food processor for 20–30 seconds before mixing it with the other ingredients.

If you enjoy a more textured filling, leave the cottage cheese as it is.

5. Begin Layering

Spread approximately ½ cup marinara sauce across the bottom of the prepared baking dish.

Arrange a layer of lasagna noodles over the sauce.

Spread approximately one-third of the cottage cheese mixture over the noodles.

Add one-third of the mushroom and spinach mixture.

Spoon marinara sauce over the vegetables.

Sprinkle with mozzarella.

6. Repeat the Layers

Repeat the layering process:

1. Lasagna noodles
2. Cottage cheese mixture
3. Mushrooms and spinach
4. Marinara sauce
5. Mozzarella

Continue until the ingredients are used.

Try to distribute the ingredients evenly so every serving contains noodles, creamy cheese, vegetables, sauce, and melted cheese.

7. Finish the Lasagna

Place the final layer of noodles on top.

Spread the remaining marinara sauce over the noodles.

Sprinkle generously with the remaining mozzarella.

Finish with Parmesan.

For an especially golden top, add a little extra mozzarella.

8. Bake

Cover the baking dish tightly with aluminum foil.

Bake for approximately 25 minutes.

Remove the foil and continue baking for another 15–20 minutes, until the cheese is melted, bubbling, and golden.

If you want a deeper golden crust, place the lasagna under the broiler for approximately 1–2 minutes.

Watch carefully because the cheese can burn quickly.

9. Rest Before Serving

Remove the lasagna from the oven.

Allow it to rest for 10–15 minutes before slicing.

This step is important.

Resting allows the layers to settle, making the lasagna easier to cut and preventing the sauce from running everywhere.

Garnish with fresh parsley or basil.

Serve warm.

Notes

Cottage Cheese Texture

Cottage cheese gives the filling a creamy texture and adds protein.

If you don’t like the texture of cottage cheese, blend it until smooth before using.

Mushrooms

Cremini, white button, baby bella, or portobello mushrooms can be used.

For the best flavor, don’t overcrowd the skillet while cooking.

Spinach

Fresh spinach is ideal, but frozen spinach can also be used.

If using frozen spinach, thaw it completely and squeeze out as much water as possible before adding it to the lasagna.

Marinara Sauce

Use your favorite high-quality marinara sauce.

A tomato-basil sauce also works beautifully.

Cheese

Mozzarella provides the classic stretchy topping, while Parmesan adds salty, nutty flavor.

You can also add provolone, fontina, or ricotta if desired.

Tips for the Best Cottage Cheese Lasagna

1. Cook the Mushrooms Thoroughly

Don’t rush the mushroom step.

They should release their moisture and become lightly browned.

This gives them much more flavor and helps prevent watery lasagna.

2. Drain Spinach Properly

If using frozen spinach, squeeze it very dry.

Excess water is one of the biggest causes of watery vegetable lasagna.

3. Don’t Overfill Each Layer

Too much filling can make the lasagna difficult to cut.

Moderate, even layers work best.

4. Season the Cottage Cheese

Plain cottage cheese can taste bland on its own.

Italian seasoning, garlic, Parmesan, black pepper, and oregano make a huge difference.

5. Don’t Skip the Resting Period

Allowing the lasagna to rest helps the layers firm up.

6. Use Freshly Grated Parmesan

Fresh Parmesan melts and tastes better than many shelf-stable alternatives.

7. Don’t Overcook

Once the cheese is melted and bubbling and the center is hot, the lasagna is ready.

How to Make the Filling Extra Creamy

For a smoother, richer filling, blend the cottage cheese before adding the egg and seasonings.

You can also add 2–3 tablespoons of cream cheese to the mixture.

Another option is to mix cottage cheese with a small amount of ricotta.

This creates a particularly luxurious filling.

How to Add More Vegetables

This recipe is easy to customize with additional vegetables.

Good choices include:

• Zucchini
• Bell peppers
• Eggplant
• Roasted red peppers
• Broccoli
• Carrots
• Kale
• Artichoke hearts

Make sure vegetables with high water content are cooked first so they don’t release excess liquid into the lasagna.

Protein Variations

Although this is designed as a vegetarian lasagna, you can add protein if desired.

Try:

• Shredded chicken
• Ground turkey
• Italian sausage
• Cooked lentils
• White beans

For a vegetarian high-protein option, add cooked lentils or white beans between the layers.

Spicy Version

For extra heat, add:

• Red pepper flakes
• Calabrian chili paste
• Chopped jalapeño
• Hot Italian sausage
• A drizzle of chili oil

Keep the spice moderate if serving children.

Make-Ahead Instructions

This lasagna is excellent for preparing ahead.

Assemble the entire lasagna, cover it tightly, and refrigerate for up to 24 hours before baking.

When ready to cook, remove it from the refrigerator and allow it to sit at room temperature for approximately 15–20 minutes.

Bake according to the recipe, adding additional time if necessary because the lasagna will be cold.

For the freshest texture, add the final cheese topping immediately before baking.

Freezer Instructions

You can freeze this lasagna either before or after baking.

Freezing Before Baking

Assemble the lasagna in a freezer-safe baking dish.

Wrap it tightly with plastic wrap followed by aluminum foil.

Freeze for up to approximately 2–3 months for best quality.

Thaw overnight in the refrigerator before baking.

Freezing After Baking

Allow the cooked lasagna to cool completely.

Cut into individual portions and store in freezer-safe containers.

This makes convenient ready-to-reheat lunches or dinners.

Storage

Store leftover lasagna in an airtight container in the refrigerator.

It will keep for approximately 3–4 days.

Reheat individual portions in the microwave or reheat larger portions in a covered oven-safe dish at 350°F (175°C) until hot.

If the top becomes dry during reheating, add a small spoonful of marinara sauce before warming.

Serving Suggestions

Serve this lasagna with a simple side dish to create a complete meal.

Fresh Green Salad

A crisp salad with lettuce, cucumber, tomatoes, and lemon vinaigrette provides freshness.

Garlic Bread

Warm garlic bread is perfect for dipping into extra marinara sauce.

Roasted Vegetables

Roasted broccoli, asparagus, zucchini, or green beans make excellent sides.

Tomato Salad

Fresh tomatoes with basil, olive oil, and balsamic vinegar provide a bright contrast.

Soup

Serve with a light vegetable or tomato soup for a cozy Italian-inspired dinner.

Servings

This recipe makes approximately 6–8 servings.

For a larger gathering, double the recipe and bake in two 9×13-inch dishes.

If using a smaller dish, avoid making the lasagna too deep because the center may take significantly longer to heat.
