• Lower in fat: Using a light Alfredo sauce and part-skim cheeses ensures all the creaminess without unnecessary calories or saturated fats.

Wholesome Ingredients for This Spinach Alfredo Lasagna

Great recipes begin with quality ingredients. Here’s a closer look at some of the MVPs in this homemade alfredo spinach lasagna and how they contribute to its wholesome appeal:

• Spinach: This nutrient powerhouse is rich in antioxidants, iron, and vitamin C, which are key for energy and immunity. If fresh spinach is available, you can swap it for frozen—just sauté it first to remove excess moisture.
• Part-skim ricotta cheese: A creamy base without the extra fat. For an even healthier option, try blending cottage cheese until smooth!
• Whole-grain lasagna noodles: These add fiber and nutrients for longer-lasting energy. Gluten-free noodles can be used as an alternative to make the dish gluten-free.
• Light Alfredo sauce: Opt for a light version to cut down on unnecessary calories. For a plant-based option, use a creamy cashew Alfredo sauce.

How to Make Spinach Alfredo Lasagna

2. In a medium-sized bowl, combine the egg, ricotta cheese, thawed spinach, minced garlic, and black pepper until well blended.
3. In another bowl, whisk together the light Alfredo sauce and milk to create a smoother sauce.
4. Spread about 1/2 cup of the Alfredo mixture evenly across the bottom of the prepared baking dish.
5. Layer 3 uncooked lasagna noodles on top, making sure they don’t overlap.
6. Spread half of the ricotta-spinach mixture over the noodles and cover with half of the shredded carrots and half of the mushrooms.
7. Repeat the layers with 3 more lasagna noodles, the remaining ricotta-spinach mixture, and the rest of the carrots and mushrooms.
8. Pour the remaining Alfredo sauce mixture over the top, ensuring everything is well coated. Sprinkle with mozzarella and Parmesan cheeses.
9. Lightly coat a piece of foil with nonstick spray and cover the lasagna with the foil, sprayed side down.
10. Bake for 60-70 minutes, then uncover and bake for another 15-20 minutes or until the top is golden brown and bubbly.
11. Let the lasagna stand for 20 minutes before slicing to serve.
