Recipe Overview
- Prep Time: 20 minutes
- Cook Time: 40 minutes
- Total Time: 1 hour
- Yields: 5 servings
Ingredients
- 12 ounces potato gnocchi (shelf-stable or refrigerated)
- 14 ounces boneless, skinless chicken breasts or thighs, diced into half-inch pieces
- 1 1/2 cups small broccoli florets
- 3/4 cup fire-roasted bell peppers, drained and sliced
- 1 container (11 ounces) refrigerated Alfredo sauce
- 2/3 cup chicken bone broth
- 3 tablespoons prepared basil pesto
- 3 cloves garlic, finely minced
- 1/2 teaspoon Italian seasoning
- 1/2 teaspoon fine salt (adjust to taste)
- 1/4 teaspoon freshly ground black pepper
- 1 pinch red pepper flakes (optional, for a subtle kick)
- 1/3 cup grated Parmesan cheese, divided
- 1 cup shredded mozzarella cheese
- 1/3 cup plain or panko breadcrumbs
- 2 teaspoons extra-virgin olive oil
- 1 teaspoon fresh lemon juice
- Fresh parsley or basil, finely minced (for garnish)
Step-by-Step Instructions
1. Preparation and Assembly
- Preheat your oven to 375°F (190°C). Thoroughly grease an 8×8-inch baking dish with butter, oil, or non-stick cooking spray.
- Scatter the uncooked gnocchi, diced chicken pieces, broccoli florets, and drained fire-roasted bell peppers directly into the prepared baking dish, distributing them evenly.
2. Mixing the Sauce
- In a medium mixing bowl, whisk together the refrigerated Alfredo sauce, chicken bone broth, basil pesto, minced garlic, Italian seasoning, salt, black pepper, red pepper flakes, and 2 tablespoons of the grated Parmesan cheese until completely smooth.
- Pour this creamy mixture evenly over the ingredients in the baking dish. Stir gently to ensure every piece of gnocchi, chicken, and vegetable is well-coated.
3. Topping the Casserole
- Sprinkle the shredded mozzarella cheese and the remaining Parmesan cheese uniformly across the top of the casserole.
- In a small bowl, toss the breadcrumbs together with the olive oil until evenly moistened, then scatter them evenly over the cheese layer to guarantee a crispy topping.
4. Baking Process
- Cover the baking dish tightly with aluminum foil to trap the steam, allowing the gnocchi to cook thoroughly without drying out.
- Bake in the preheated oven for 30 minutes covered.
- Carefully remove the foil and bake for an additional 10 to 15 minutes, or until the cheese is melted, bubbling at the edges, and the breadcrumbs are a light golden brown.
5. Resting and Serving
- Remove the bake from the oven and let it rest uncovered for 5 to 10 minutes to allow the sauce to thicken slightly.
- Drizzle the fresh lemon juice over the top, garnish with minced parsley or basil, and serve warm.
Chef’s Cooking Tips
Check the Salt
Because store-bought Alfredo sauce, broth, and cheeses can vary widely in sodium content, taste your sauce mixture before adding extra salt to prevent over-seasoning.
Gnocchi Selection
Both shelf-stable and refrigerated potato gnocchi work wonderfully in this recipe. There is no need to pre-boil them; they soften and absorb the savory flavors perfectly while baking.
Even Chicken Sizing
Cut your chicken into uniform half-inch cubes so they cook evenly alongside the gnocchi and vegetables in the oven.
