Step 1: Cook the Pasta and Broccoli
- Boil the Pasta: Cook the pasta in a large pot of salted boiling water according to package directions until al dente. Drain and set aside.
- Steam the Broccoli: While the pasta is cooking, steam the broccoli until it’s tender but still bright green, about 4-5 minutes. Drain and set aside.
Step 2: Make the Creamy Sauce
- Sauté the Onion and Garlic: In a large skillet, heat the olive oil over medium heat. Add the diced onion and cook until softened, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.
- Make a Roux: Stir in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
- Add the Liquids: Gradually whisk in the chicken broth, milk, and heavy cream (if using). Continue whisking until the mixture is smooth and starts to thicken, about 4-5 minutes.
- Add Cheese and Seasonings: Stir in the cheddar cheese, Parmesan, Dijon mustard, dried thyme, salt, and pepper. Cook until the cheese has melted and the sauce is creamy.
Step 3: Combine the Ingredients
- Mix Chicken, Pasta, and Broccoli: In a large mixing bowl, combine the cooked chicken, drained pasta, and steamed broccoli.
- Add the Sauce: Pour the creamy cheese sauce over the chicken, pasta, and broccoli mixture. Stir everything together until well coated.
Step 4: Assemble and Bake
- Transfer to Baking Dish: Grease a 9×13-inch baking dish and pour the mixture into the dish, spreading it out evenly.
- Add Topping (Optional): If you’re using breadcrumbs, mix the breadcrumbs with melted butter and sprinkle them over the top of the casserole for a crispy finish.
- Bake: Preheat the oven to 375°F (190°C) and bake the pasta bake for 20-25 minutes, or until the top is golden and bubbly.
Step 5: Serve
- Garnish: You can sprinkle extra Parmesan or chopped parsley on top before serving.
- Serve Hot: Enjoy this creamy and hearty casserole right out of the oven!
Tips for Success:
- Make Ahead: You can assemble the casserole ahead of time and store it in the fridge. When ready to bake, add an extra 10 minutes to the baking time.
- Substitutions: Swap the chicken for turkey or ham, or use different veggies like spinach or mushrooms for a variation.
- Gluten-Free Option: Use gluten-free pasta and flour to make this dish suitable for gluten-sensitive diets.
