Wholesome Ingredients for This Spinach Mushroom Lasagna

When it comes to healthy, homemade meals, ingredient quality makes all the difference. Here are the star players in our homemade spinach mushroom lasagna and why they’re so beneficial:

• Spinach: A nutrient powerhouse, spinach provides vitamins A, C, and K alongside iron and fiber. If fresh isn’t available, frozen spinach works wonderfully—just make sure to squeeze out excess moisture.
• Cremini Mushrooms: These earthy mushrooms add umami depth while being low in calories and high in selenium, an essential mineral for antioxidant function.
• Ricotta Cheese: Creamy and protein-rich, ricotta gives this dish its velvety texture without weighing it down. Substitute with cottage cheese for a lighter option.
• No-boil Lasagna Noodles: A true time-saver! They soften perfectly during baking, absorbing all the flavors of the marinara sauce.

Pro tip: Opt for organic or locally-sourced ingredients whenever possible to maximize freshness and nutritional value.

How to Make Spinach Mushroom Lasagna

1. Prep: Preheat your oven to 350°F (177°C). Lightly grease a 9×13-inch baking dish with oil.
2. Sauté vegetables: Heat olive oil in a large skillet over medium heat. Sauté diced onions and mushrooms until soft and fragrant, about 10 minutes. Add garlic, fresh spinach, and ¼ teaspoon salt. Cook until spinach is wilted and bright green.
3. Prepare cheese mixture: In a medium bowl, stir together ricotta cheese, eggs, ½ teaspoon salt, and ¼ teaspoon pepper until smooth.
4. Layer the lasagna: Spread 1 cup of marinara sauce evenly on the bottom of the dish. Add three lasagna noodles, followed by half the ricotta mixture. Sprinkle with one-third of the parmesan and mozzarella, then half of the spinach mixture. Repeat layers, finishing with noodles, sauce, and the remaining mozzarella and parmesan.
5. Bake: Cover loosely with aluminum foil and bake for 30 minutes. Remove foil, then bake another 10-15 minutes until the cheese is bubbly and golden brown. Let sit for 5-10 minutes before slicing to serve.
