This cheesy chicken casserole is made with chicken, creamy mushroom sauce, and melted cheese on top! Chicken Gloria is a comfort food dish that's easy to make and packed with flavor.
Add onions and garlic to skillet and saute until almost translucent. If needed, add more butter to the skillet.
Add mushrooms and thyme and saute for 4 to 5 minutes, stirring often.
½ teaspoon dried thyme
Add broth and deglaze the pan (using a wooden spoon, scrape the bottom of the pan so all cooked-on bits come off; this is flavor).
¾ cup chicken broth
Give the milk and cornstarch mixture a stir and add to the skillet. Simmer the sauce until thickened.
Arrange cooked chicken in your baking dish.
Pour the mushroom sauce over the chicken. Using kitchen tongs, move the chicken around so the sauce has a chance to get onto the bottom of the dish too.
Place slices of cheese on top of the chicken and sauce.
6 to 8 slices of Muenster cheese
Bake the dish for 10 to 15 minutes OR until the cheese is melted and the sauce is bubbling around the edges.
Notes
Use chicken thighs in place of chicken breast. They have more flavor thanks to dark meat.
Use mozzarella or gouda for the cheese topping. You need a soft, creamy cheese that melts well.
Any leftovers should be stored in a container with a lid, in the fridge, for up to 3 days.
To make ahead: prepare the chicken and sauce, cool them completely, and store them in the fridge separately. Pull them out of the fridge and let them come to room temperature. Arrange chicken in a baking dish, mix the sauce with a splash of water for better texture (it will thicken as it refrigerates) and pour over the chicken. Top with cheese and bake.
