Preparing Skinny Mushroom Spinach Lasagna
Creating a flavorful skinny mushroom spinach lasagna is easier than you might think! With just a few fresh ingredients and some love in the kitchen, you’ll have a dish that pleases both vegetarians and meat-lovers alike. Let’s walk through the steps to prepare this tantalizing pasta bake that’s perfect for any occasion.
Sauté the vegetables
Start by melting 2 tablespoons of salted butter in a large skillet over medium heat. Toss in ½ cup of chopped onions, and you'll want to sauté them for about 2 minutes until they turn a lovely translucent shade. Next, add in 2 cups of chopped mushrooms and continue cooking for another 3-4 minutes. The aroma of sautéing mushrooms is simply irresistible! After that, stir in 2 tablespoons of minced garlic, along with 2 packages of defrosted spinach (make sure to squeeze out excess water). Add a pinch of salt, pepper, ¼ teaspoon of red pepper flakes for a gentle kick, and ¼ teaspoon of nutmeg to elevate the flavors. Sauté everything just long enough for the ingredients to mingle—about a minute should do!
Prepare the ricotta mixture
While those beautiful veggies are cooking, let’s turn our attention to the silky ricotta mixture. In a large bowl, combine 30 ounces of non-fat ricotta cheese with one large egg and ¼ cup of grated parmesan cheese. This creamy combination is what will bring richness to your skinny mushroom spinach lasagna. Once combined, fold in the sautéed vegetable mixture, making sure everything is well incorporated.
Layering the lasagna
Now comes the fun part! You'll want to position a rack in the middle of your oven and preheat it to 375 degrees Fahrenheit. Grab a 9x13 baking dish and spread a thin layer of marinara sauce on the bottom. Start layering with 3 cooked whole wheat lasagna noodles, followed by half of your ricotta and veggie mixture, ⅓ of the marinara sauce, and then ⅓ of your part-skim mozzarella cheese (about 2 cups total). Repeat these layers until everything is used, ensuring that you finish with noodles topped with marinara and a generous amount of mozzarella.
Baking the lasagna
Cover your baking dish with foil and pop it in the oven to bake for 20 minutes. After that, remove the foil and bake uncovered for another 10 minutes, allowing the cheese to get bubbly and slightly golden. Your kitchen will be filled with delicious aromas at this point, tempting everyone around!
Resting and serving the lasagna
Once baked, it's crucial to let the skinny mushroom spinach lasagna rest for about 10-15 minutes. This resting period helps the noodles absorb any excess sauce and makes serving much easier. Now, slice into the lasagna and serve warm, enjoying this hearty and nutritious dish with friends or family.
And there you have it! A beautiful, healthy twist on a classic lasagna that's sure to become a favorite in your home. Enjoy!
