Spicy Sausage, Spinach, and Mushroom Lasagna

Directions

1. Preheat oven to 375°F.
2. Cook pasta according to package directions. Lightly spray noodles with nonstick cooking spray when finished to prevent sticking; set aside.
3. Meanwhile, heat large skillet over medium-high heat. Add sausage and onion to skillet. Cook 10 minutes or until browned and cooked through, breaking into crumbles, stirring occasionally. Add garlic; cook 1 minute or until fragrant. Drain any excess liquid. Stir in 2 cups of the marinara sauce. Remove mixture from heat; reserve sausage-marinara sauce.
4. Wipe skillet clean with paper towel. Add spinach and mushrooms to skillet. Cook over medium heat about 5 minutes, stirring occasionally. Add 1 to 2 tablespoons water if necessary to prevent sticking. Season with salt and pepper, as desired.
5. In small bowl, whisk together ricotta, basil, red pepper flakes and Italian seasoning; set aside.
6. To assemble lasagna, spray 9X13-inch baking dish with nonstick cooking spray. Spread 1/2 cup of remaining plain marinara sauce on bottom of dish. Add a layer of lasagna noodles, half of ricotta cheese mixture, half of spinach mixture, and half of sausage-marinara sauce. Sprinkle with 3/4 cup of the mozzarella cheese. Repeat for next layer. To finish lasagna, add one layer of noodles and remaining 1/2 cup plain marinara sauce. Sprinkle with remaining 1/2 cup mozzarella cheese and the 1/4 cup Parmesan cheese.
