Gluten Free Chicken Broccoli Casserole Recipe
Preheat oven to 350°F and lightly grease a 9 x 13 casserole dish with nonstick cooking spray.
Cook the pasta in lightly salted water to al dente according to package directions. During the last 3 minutes of cooking the pasta, add the broccoli florets. Before draining the pasta and broccoli, reserve ½ cup of the pasta water. Drain and transfer the pasta and broccoli to the prepared casserole dish.
In a medium saucepan, heat the oil over medium heat. Add the shallot and cook until it begins to brown and turns translucent. Add the garlic and flour; cook for 1 minute.
Add the stock, reserved water and milk while whisking constantly until fully incorporated. Add the cornstarch and stir until completely dissolved. Bring the mixture to a simmer and cook until the sauce begins to thicken, about 3 to 5 minutes.
Remove from heat. Add the chicken, black pepper, rosemary, sage, paprika and salt; stir until well combined. Pour chicken mixture over the pasta and gently stir to combine. Top with shredded cheddar cheese.
In a small mixing bowl, combine the corn flakes and butter. Add the black pepper and stir to combine. Sprinkle evenly over the casserole.
Bake uncovered for 15 to 20 minutes, until casserole is hot and bubbling in the center. Remove from oven and allow to rest for 5 minutes. Garnish with sliced green onion and enjoy immediately.
