Spinach and Mushroom Lasagna is full of flavor and richness. It can be made with either a tomato based sauce such as my Homemade Marinara Sauce, or a cream based sauce. As we continue our quest to focus more on vegetarian meals, this Spinach and Mushroom Lasagna is a winner.
The ingredients for this delicious Lasagna include cremini mushrooms, my homemade marinara sauce, chopped spinach, homemade ricotta cheese, egg, lasagna noodles, mozzarella cheese, and Parmesan cheese.
Before building the lasagnas (I made two small ones as opposed to one big one) I prepped the different ingredients. Starting with the cremini mushrooms, I pulse chopped them in my food processor until they resembled cooked crumbled ground beef. It took about 5 pulses to do this. Then, I cooked them in a little bit of olive in a Dutch oven over medium high heat until most of the liquid was absorbed. Next, I added the marinara sauce to the mushrooms, gave it a stir and removed it from the heat. Finally, I let the Master Taste Tester try it, and got a thumbs up!
To build the Spinach and Mushroom Lasagna, first I thawed the spinach and squeezed as much water as possible from it. Then I mixed the ricotta cheese with the egg and shredded the mozzarella cheese. Finally, I cooked the lasagna noodles according to the package directions.
The assembly of the lasagnas went like this:
- Layer 1: Mushroom/marinara mixture, lasagna noodles, spinach, mozzarella cheese, Parmesan cheese.
- Layer 2: Mushroom/marinara mixture, lasagna noodles, ricotta cheese, spinach, mozzarella cheese, Parmesan cheese.
- Layer 3: Mushroom/marinara mixture, lasagna noodles, ricotta cheese, spinach, mozzarella cheese, Parmesan cheese.
Into a 375° F oven one of the Spinach and Mushroom Lasagnas went for 35 minutes, until it was nicely browned and bubbly. It was absolutely delicious. In fact, if I hadn’t known that it was meatless, I never would have guessed it. Yum!
To complete your meal, serve the Spinach and Mushroom Lasagna with a Caesar Salad and some Breadsticks. If you’re looking for a Lasagna that has meat, check out my Classic Lasagna or Six Cheese Turkey Lasagna.
