Preheat the Oven
Preheat your oven to 400°F (200°C). Prepare your casserole dish by spraying it thoroughly with non-stick baking spray to prevent the cheesy mixture from sticking during baking.
Cook the Gnocchi
Cook the gnocchi according to the package directions, typically boiling for 2-3 minutes until they float to the surface. Drain them well to prevent excess water from diluting the Alfredo sauce in the final dish.
Combine Ingredients
In a large mixing bowl, gently combine the cooked gnocchi, frozen broccoli, shredded chicken, crumbled bacon, minced garlic, and Alfredo sauce. Stir carefully to ensure all ingredients are evenly coated with sauce while maintaining the gnocchi's delicate texture.
Assemble and Bake
Transfer the mixture into your prepared casserole dish, spreading it evenly. Sprinkle the top generously with the shredded mozzarella and Monterey Jack cheeses, creating a melty, golden topping. Bake in the preheated oven for 20 minutes until the cheese is melted and the edges begin to bubble.
Broil for Color
Switch your oven to broil setting and cook for an additional 1-2 minutes, watching carefully, until the cheese develops a beautiful golden-brown color. This step adds extra flavor and visual appeal to your dish.
Garnish and Serve
Remove from the oven and finish with optional garnishes of freshly grated Parmesan cheese, sliced green onions, and additional bacon bits if desired. Serve immediately while hot and bubbling for the best flavor and texture.
