How to make a keto chicken casserole
Chicken casseroles are simple to make: the only thing you’ll need to remember to do is to adjust the par-baking time depending on which vegetables you use.
Thicker vegetables like Brussels sprouts require more time to cook, but adjust this to what you are using. Follow the easy 3-step process to make it:
Start by adding the vegetables, spices, and olive oil into a baking dish (casserole dish), cover, and bake until the vegetables are fork tender.
Step 2- Sear
Next, season the chicken with salt and pepper and cook in a skillet for several minutes until no longer pink and almost cooked through.
Step 3- Bake
Now, remove the baking dish from the oven and stir through the chicken. Cover with cheese and bake until it’s bubbling and nicely melted.
Can you cook raw chicken in a casserole dish?
Unless all the vegetables are of the chunkier variety (think cauliflower, pumpkin, carrots, or rutabagas), it’s not recommended as you risk the chicken being undercooked.
Also, the chicken releases juices into the casserole, which will become watery and lack flavor.
