01 - Preheat the oven to 375°F. Lightly grease a 9x13-inch baking dish with olive oil.
02 - In a large skillet over medium heat, melt the butter. Add garlic and red pepper flakes, sauté for 1 minute until fragrant.
03 - Add shrimp; season lightly with salt and pepper. Cook for 2–3 minutes until just pink. Remove shrimp with a slotted spoon and set aside.
04 - Add white wine to the skillet, scraping up any browned bits. Simmer for 2–3 minutes until slightly reduced. Add lemon juice, zest, and parsley. Remove from heat.
05 - In a bowl, combine ricotta, half the Parmesan, egg, salt, and black pepper. Mix until smooth.
06 - Spread ⅓ of the scampi sauce on the bottom of the baking dish. Layer 3 noodles over the sauce. Spread ½ of the ricotta mixture, then arrange ½ of the shrimp on top. Sprinkle with ⅓ of the mozzarella.
07 - Repeat with another ⅓ of sauce, 3 noodles, remaining ricotta, remaining shrimp, and another ⅓ of mozzarella.
08 - Top with final 3 noodles, remaining sauce, remaining mozzarella, and Parmesan.
09 - Cover with foil and bake for 25 minutes.
10 - Remove foil and bake for another 15 minutes, until bubbly and golden.
11 - Let rest 10 minutes before slicing. Garnish with extra parsley and lemon zest if desired.
