Mushroom and Spinach Lasagna Ingredients
For the Vegetables
- Mushrooms – Choose cremini or button mushrooms for their earthy flavor and tender texture that’s perfect in Mushroom and Spinach Lasagna.
- Fresh Spinach – Use baby spinach for mildness and quick wilting; it adds vibrant color and nutrients.
- Garlic Cloves – Mince finely to infuse a warm, aromatic depth that complements the veggies.
- Onion – Dice small to create a sweet base without overpowering the layers.
For the Cheese Mixture
- Ricotta Cheese – Provides creamy richness and a mild tang that balances the savory vegetables.
- Mozzarella Cheese – Use shredded for melty, stretchy goodness on top and between layers.
- Parmesan Cheese – Finely grated for a sharp, nutty finish that enhances every bite.
- Egg – Helps bind the ricotta mixture so layers hold perfectly after baking.
For the Sauce and Assembly
- Marinara Sauce – Choose a smooth tomato sauce with a hint of herbs for a fresh, zesty contrast.
- Lasagna Noodles – No-boil noodles save time and soak up flavors wonderfully during baking.
- Olive Oil – Use for sautéing mushrooms and onion, adding a fragrant richness.
- Fresh Basil or Italian Herbs – Optional, chopped finely to sprinkle for a fragrant herbal lift.
How to Make Mushroom and Spinach Lasagna
- Preheat Oven: Preheat to 375°F (190°C). Lightly oil a 9×13-inch baking dish so layers won’t stick and edges turn golden brown during baking.
For the Veggie Filling:
-
Sauté Veggies: Heat olive oil in a skillet over medium heat. Add onions, garlic, and mushrooms; cook until soft and juices evaporate, about 5 minutes.
-
Wilt Spinach: Add baby spinach in batches; stir until just wilted, about 2 minutes. Season with salt, pepper, and Italian herbs, then remove from heat.
For the Cheese Mixture:
-
Mix Cheese: In a medium bowl, stir together ricotta, egg, half the Parmesan, and a pinch of salt until smooth and creamy, then set aside to bind layers perfectly.
-
Layer Sauce: Spread a thin coating of marinara sauce evenly in the baking dish; this prevents noodles from sticking and infuses vibrant tomato flavor.
-
Assemble Layers: Arrange no-boil noodles over sauce, gently scoop half the veggie filling, dot with half the cheese mix, and sprinkle mozzarella. Repeat layers.
-
Top & Bake: Finish with a final noodle layer, sauce, mozzarella, and remaining Parmesan. Cover loosely with foil and bake for 25 minutes until bubbly.
-
Brown & Set: Remove foil and bake 10 more minutes until cheese bubbles and turns golden. Let stand 10 minutes to set for clean slices.
Optional: Sprinkle chopped basil before serving for a fresh, aromatic finish.

Mushroom and Spinach Lasagna Recipe FAQs
What kind of mushrooms work best for Mushroom and Spinach Lasagna?
Cremini or button mushrooms are my top picks for this recipe. They have an earthy flavor and firm texture that hold up nicely during sautéing and baking, adding depth without getting soggy.
How should I store leftover Mushroom and Spinach Lasagna, and for how long?
Absolutely store leftovers in an airtight container in the fridge. They’ll stay fresh for 3 to 4 days. Just reheat gently in the microwave or oven to bring back that creamy, comforting vibe without drying it out.
Can I freeze the lasagna? If so, what’s the best way to do it?
Very much yes! To freeze, wrap your fully baked lasagna tightly with aluminum foil or place it in a freezer-safe container. Label it and freeze for up to 3 months. When ready to enjoy, thaw it overnight in the fridge. Reheat uncovered in a 350°F (175°C) oven for 25-30 minutes until bubbly and warm. For extra moisture, add a spoonful of marinara before reheating.
Why is my Mushroom and Spinach Lasagna watery or too soggy?
This can happen if the veggies release too much water. To avoid this, sauté mushrooms and spinach just until wilted and most moisture evaporates. Also, avoid over-layering sauce and ensure your ricotta mixture is well bound with egg to maintain structure without excess wetness.
Is this Mushroom and Spinach Lasagna suitable for people with dairy allergies or pets?
This classic version contains dairy-rich cheeses, so it’s not suitable for dairy allergies or pets. However, you can swap in dairy-free ricotta and mozzarella alternatives to keep it allergen-friendly. And a quick safety note: never share lasagna with pets—ingredients like onions and garlic can be harmful to them.
