Ingredients for Spinach Mushroom Lasagna
Essential ingredients overview
Creating a delicious Spinach Mushroom Lasagna hinges on selecting the right ingredients. Here’s what you’ll need to whip up this comforting dish:
- Olive oil: A must-have for sautéing your veggies.
- Onion and cremini mushrooms: These create a rich base, adding depth of flavor to your lasagna.
- Garlic: For that aromatic kick we all love.
- Spinach: Essential for that vibrant green layer!
- Ricotta cheese and eggs: This combo serves as the creamy filling, making each bite heavenly.
- Pasta sauce: Whether store-bought or homemade, this ties all the flavors together.
- Lasagna noodles: No-boil works perfectly if you want to simplify prep time.

Fresh vs. frozen spinach
Now, when it comes to spinach, you have two great options: fresh or frozen. Fresh spinach lends a brighter taste and vibrant color, while frozen spinach offers convenience. If you choose frozen, just remember to squeeze out the excess moisture after thawing. This ensures your lasagna won’t become watery. Whichever type you pick, spinach is a nutrient powerhouse that adds flavor and a healthy touch to your dish. Want more tips on using spinach?

Preparing Spinach Mushroom Lasagna
Preheat and Grease the Baking Dish
Before diving into the exciting assembly of your Spinach Mushroom Lasagna, it’s essential to start with the basics: preheating your oven! Set it to 350°F (177°C) so it’s ready to work its magic as soon as your dish is assembled. Next, grab a 9x13-inch baking dish or a 3-quart dish and lightly grease it with olive oil. This simple step ensures your lasagna comes out effortlessly, without sticking to the sides, promising a beautifully intact serving.
Make the Mushroom and Spinach Filling
With your oven preheated and the dish prepared, it’s time to create the delightful filling that gives this Spinach Mushroom Lasagna its signature flavor. Heat 1 tablespoon of olive oil in a large skillet over medium heat. Toss in finely diced onions and chopped cremini mushrooms, stirring occasionally for about 10 minutes until the onions are translucent and the mushrooms have released their moisture. Add in a finely minced garlic clove, followed by 10 cups of fresh spinach. Season with a pinch of salt (about ¼ teaspoon) and cook until the spinach leaves are bright green and have wilted. This mixture not only adds depth but also packs a nutritious punch!
Prepare the Cheese Mixture
Next, we’ll create a creamy and indulgent cheese layer. In a medium bowl, combine 15 ounces of ricotta cheese with 2 large beaten eggs. This forms the robust base for your lasagna's cheesy goodness. Stir in ½ teaspoon of salt and ¼ teaspoon of pepper to elevate the flavors. This mixture is what will bind the ingredients together, adding a delightful creaminess to each bite.
Layering the Lasagna
Now comes the fun part—assembling your Spinach Mushroom Lasagna! Spread about 1 cup of your favorite pasta sauce on the bottom of the greased baking dish. Lay down three no-boil lasagna sheets, covering the sauce. Top this with half of your ricotta mixture, sprinkling over a third of both the finely grated parmesan and mozzarella cheeses. Next, add half of the spinach and mushroom filling, followed by another ½ cup of pasta sauce. Repeat the layering process with the remaining ingredients, finishing with a layer of noodles topped off with sauce, mozzarella, and parmesan. This multi-layered approach builds flavor and texture, making every forkful a delight.
Bake to Perfection
Finally, it’s time to bake your masterpiece. Loosely cover the lasagna with aluminum foil to retain moisture and pop it in the oven for about 30 minutes. After this initial bake, uncover the dish and let it bake for an additional 10 to 15 minutes, until the cheese is bubbling and golden brown. Love a little extra crunch? Broil it for 1 to 2 minutes at the end for that perfect crispy top! Once done, let it sit for about 5 to 10 minutes before slicing to allow the layers to set.
Enjoy your rich and flavorful Spinach Mushroom Lasagna, and remember, it often tastes even better the next day—a perfect meal prep choice!

Variations on Spinach Mushroom Lasagna
Spinach mushroom lasagna is a versatile dish that you can customize to suit your taste. Here are a couple of delicious variations to consider.
Add Protein with Chicken Ham
For those looking to boost their protein intake, adding chicken ham is a fantastic option. Simply layer thin slices between the noodles for a juicy, savory twist. It complements the earthiness of mushrooms perfectly, making each bite even more satisfying.
Make it Vegan with Cashew Cheese
If you’re leaning towards plant-based eating, consider substituting traditional cheeses with homemade cashew cheese. Blend soaked cashews with nutritional yeast, garlic, and a splash of lemon juice for a creamy filling that mimics ricotta. This vegan version of spinach mushroom lasagna will delight your taste buds without sacrificing flavor.
These variations are just a starting point—get creative!
