Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
In a large bowl, combine ricotta, drained spinach, roasted red peppers, onion, garlic, Italian seasoning, salt, and pepper. Mix until well combined.
Spread a thin layer of pasta sauce on the bottom of the baking dish.
Layer lasagna noodles over the sauce, then spread the ricotta mixture evenly. Sprinkle mozzarella and Parmesan cheese on top.
Repeat the layers until all ingredients are used, finishing with sauce, mozzarella, and Parmesan on top.
Cover with foil and bake for 25–30 minutes. Remove foil and bake an additional 10–15 minutes until golden and bubbly.
Let rest for 10–15 minutes before slicing. Serve warm.

Press spinach to remove excess water to keep the ricotta creamy. Let the lasagna rest before slicing for better presentation.
