Directions for how to make Chicken Brussels Sprouts Casserole Recipe

Preheat your oven to 350 degrees Fahrenheit. 

You are going Place Brussels sprouts, the chopped carrots, chopped red pepper, green onion in a single layer and the bit of olive oil in a cast iron skillet or an oven proof skillet.

Heat your hot skillet over medium-high heat, and cook for 5 to 8 minutes. Or just until the chicken and brussel sprouts mixture begins to brown.

Remove your hot skillet from the stove top and use a slotted spoon to stir in the cooked chicken, the cream of chicken soup, the cooked white rice, the milk, the garlic powder, the onion powder and the fresh thyme and the kosher salt.

Mix your casserole together well and then sprinkle with the mozzarella and parmesan cheese. Cover your baking dish with aluminum foil. 

Bake your Chicken and Brussel Sprouts Casserole for 20 minutes. Remove the aluminum foil and then return the baking dish to the oven and cook for an additional 20 minutes. Or until baked chicken mixture is bubbly and the mozzarella and parmesan cheese just begins to brown.

Allow the casserole dish to stand for about 10 minutes before you serve your new family favorite dinner recipe! 

Hint: Sprinkle some fresh parsley over the top of your casserole for a finishing touch and pop of color!

Substitutions and Variations for our Chicken and Brussel Sprouts Casserole

We have all experimented with our basic chicken recipes and found ways to make them work better for us!

• Crispy Bacon - On a rimmed baking sheet, cook ½ pound of bacon and crumble it, adding the cooked bacon to the casserole dish just before it goes into the oven. Do not include the bacon grease.
• Cream of Mushroom Soup - You can easily substitute cream of mushroom soup for the cream of onion soup.
• Use it as a topping or stuffing - If you like the idea of these ingredients together but don't see it as a main dish, you can use it to create a stuffed or topped chicken breast dinner. Omit the cooked chicken from this casserole dish. Then cook your chicken breasts or chicken thighs separately, and spoon this casserole over it as a topping. Or you can split the chicken breasts and stuff it with the cream cheese mixture!
