Step‑by‑Step Instructions for Healthy Chicken Broccoli Pasta Casserole
Step 1: Cook Pasta and Broccoli
In a large pot, bring salted water to a rolling boil. Add your choice of pasta and cook according to package instructions until al dente, usually around 8-10 minutes. Two minutes before the pasta is finished, gently stir in the broccoli florets. Once done, drain the mixture in a colander, allowing excess water to escape, and set aside.
Step 2: Sauté Aromatics
In a large sauté pan, heat 2 tablespoons of butter or olive oil over medium-high heat. Once melted, add sliced onions and sauté for about 3 minutes until translucent. Stir in minced garlic and continue cooking for an additional 3 minutes until the garlic is fragrant and slightly golden. This aromatic base adds depth to your Healthy Chicken Broccoli Pasta Casserole.
Step 3: Make Cheese Sauce
Sprinkle ¼ cup of flour over the onion and garlic mixture, stirring constantly for 1 minute to form a roux. Gradually whisk in 2 cups of chicken stock and 1 cup of milk, making sure there are no lumps. Once smooth, add 1 tablespoon of Dijon mustard, sea salt, and fresh-cracked black pepper to taste. Simmer the sauce for 5-7 minutes until it thickens, then stir in 1 cup of shredded cheddar cheese until melted and creamy.
Step 4: Combine Ingredients
Preheat your oven to 400°F (200°C) while preparing the casserole. In a large mixing bowl, combine the drained pasta and broccoli with 2 cups of diced cooked chicken. Pour the creamy cheese sauce over the mixture and stir gently until everything is well-coated. This guarantees that each bite of the Healthy Chicken Broccoli Pasta Casserole is bursting with flavor.
Step 5: Bake
Transfer the combined mixture into a greased baking dish, spreading it evenly. Bake uncovered in your preheated oven for 15 minutes. After that, sprinkle the remaining 1 cup of shredded cheddar cheese over the top and return the dish to the oven for an additional 10 minutes. Watch for the cheese to melt and bubble with a lovely golden color, signaling that it’s ready to serve.
Step 6: Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes to set. Serve warm, straight from the dish, and prepare for the delightful reactions from your family. This Healthy Chicken Broccoli Pasta Casserole pairs wonderfully with a simple side salad or your favorite garlic bread.
