Preheat the oven to 375°F (190°C). Cook the lasagna noodles according to package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the minced garlic and red pepper flakes, cooking for about 1 minute until fragrant.
Add the shrimp to the skillet, seasoning with salt and pepper. Cook until the shrimp turn pink, about 2-3 minutes per side. Remove the shrimp from the skillet and set aside.
In the same skillet, pour in the heavy cream and chicken broth. Bring to a simmer and let it cook for about 5 minutes, stirring occasionally.
Stir in the Parmesan cheese, lemon juice, and lemon zest. Mix well until the cheese is melted and the sauce is creamy.
In a 9x13-inch baking dish, spread a thin layer of the sauce on the bottom. Layer 4 lasagna noodles over the sauce, followed by half of the shrimp and a third of the remaining sauce. Repeat the layers, finishing with the last 4 noodles and the remaining sauce on top.
Sprinkle the shredded mozzarella cheese over the top layer.
Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
Let the lasagna cool for 10 minutes before slicing. Garnish with chopped parsley before serving.
