Key Ingredients

Cottage Cheese
The base of our creamy, high-protein filling. Full-fat or low-fat both work. Blending makes it ultra-smooth.

Fresh or Frozen Spinach
Packed with fiber, iron, and flavor. Thawed frozen spinach works well—just squeeze out extra liquid.

Mushrooms
We love cremini or baby bellas for meatiness. Sauté them to deepen their flavor.

Gluten-Free Lasagna Noodles
Use brown rice or lentil-based noodles—or swap with zucchini strips for a lower-carb version.

Tomato Sauce
A no-sugar-added marinara keeps carbs down while adding bold flavor.

Mozzarella and Parmesan
Classic cheesy topping that brings everything together and browns beautifully in the oven.

Seasonings
Garlic powder, Italian herbs, salt, pepper, and optional chili flakes for a touch of heat.

Step-by-Step Instructions

Prep the Veggies and Filling

1. Preheat oven to 375°F.
2. In a skillet, sauté 2 cups chopped mushrooms with olive oil until browned. Add 3 cups spinach, stir until wilted. Season with garlic, salt, and pepper.
3. In a blender, combine:
   • 2 cups cottage cheese
   • 1 egg
   • ¼ tsp nutmeg (optional)
     Blend until smooth.

Layer and Bake

1. In a greased 8×8 baking dish, spread ½ cup tomato sauce.
2. Layer 2–3 cooked gluten-free noodles or zucchini strips.
3. Add a third of the cottage cheese mixture.
4. Add half the spinach-mushroom mixture.
5. Repeat layers, finishing with remaining sauce and 1 cup shredded mozzarella + ¼ cup parmesan.
6. Cover with foil and bake 25 minutes. Uncover and bake 10 more minutes until bubbling and golden.

Let it rest for 10–15 minutes before slicing. This helps the layers hold.

What You Must Know Before You Bake

Drain the veggies. Mushrooms and spinach release a lot of water. Sauté them until dry and pat down with paper towels if needed.

Use a blender. Blending the cottage cheese ensures a smooth, ricotta-like texture—especially if you’re serving picky eaters.

Let it sit after baking. It will firm up and slice like traditional lasagna.
