Preheat and Prepare - Start by preheating your oven to 375°F (190°C). Take a baking sheet and line it with parchment paper to prevent sticking and make cleanup easier. This preparation ensures your crescents will bake evenly and won't stick to the pan.
Mix Filling Ingredients - In a large mixing bowl, combine the shredded chicken, steamed broccoli florets, shredded cheddar cheese, mayonnaise, grated Parmesan cheese, chopped red bell pepper, chopped onion, and minced garlic. Season the mixture with salt and pepper to taste, then mix thoroughly until all ingredients are well incorporated. This creates a creamy, flavorful filling with a good balance of protein and vegetables.
Prepare Crescent Dough - Carefully unroll the crescent dough triangles and lay them flat on your prepared baking sheet. Make sure to separate them along the perforated lines to create individual triangles. Handle the dough gently to maintain its flakiness.
Fill Crescents - Spoon approximately 2-3 tablespoons of the chicken-broccoli mixture onto the wide end of each crescent triangle. Be careful not to overfill, as this could cause the filling to leak out during baking. Distribute the filling evenly among all the triangles.
Roll and Seal - Starting from the wide end where you placed the filling, roll each crescent up tightly toward the pointed end. Once rolled, tuck the corners underneath to seal the filling inside. This prevents the filling from spilling out during baking and creates a neat appearance.
Bake to Golden Perfection - Place the baking sheet in the preheated oven and bake for 12-15 minutes. Watch for the crescents to turn a beautiful golden brown color and for the dough to be completely cooked through. The internal temperature should reach at least 165°F to ensure food safety.
Cool and Serve - Once baked, remove from the oven and allow the crescents to cool for a few minutes. This brief cooling period helps the filling set slightly and makes them easier to handle. Serve while still warm for the best flavor and texture experience.
