Why this Recipe Works

Where I’m from in the midwest, we take our casseroles seriously. From old favorites that involve nothing more than a few cans of creamy soup and vegetables, to elaborate layered casseroles filled with meat and every cheese under the sun, we love them all.

The problem with most casseroles is that they tend to be filled with noodles or other starches, not to mention all the sodium.

This recipe proves you don’t need noodles, flour or canned soups to make a casserole that’s completely creamy, satisfying and flavorful! With broccoli (or your other favorite vegetables), mushrooms and tender pieces of chicken, you can make a full meal in one dish. Don’t forget to sprinkle a little fresh Parmesan on top for even more cheesiness!

You’ll love that this recipe is easy enough for a weeknight, kid approved, low carb and–of course–sugar and flour free.

Ingredient Notes

• Cooked Chicken – A great use for leftover chicken from the night before! To make this recipe even more convenient, you could grab a precooked rotisserie chicken to use instead. Cut it into cubes or shred it before adding it to the casserole.
• Broccoli – I used fresh broccoli florets. Frozen broccoli can be substituted if thawed before sauteeing.
• Mushrooms – This time I used jarred mushrooms, however fresh mushrooms would be delicious in this too.
• Whipping Cream – Real heavy whipping cream works best for thickening the sauce.
• Cheese – You need freshly grated mozzarella and Parmesan cheeses in the casserole as well as some extra Parmesan for sprinkling on top.
• Seasonings – Dried herbs and a little crushed red pepper go a long way in adding flavor

Step by Step Instructions

STEP 1. Put the cooked chicken in the bottom of a greased baking dish

STEP 2. Saute the broccoli on the stove top with garlic, and the seasonings. Add the cooked broccoli to the baking pan on top of the chicken.

STEP 3. Use the same skillet to heat the chicken broth and cream together. Stir with a wooden spoon until the sauce gets thick and bubbly, then whisk in the cheeses.

STEP 4. Pour the cheesy sauce over the chicken and broccoli. Sprinkle with more mozzarella.

STEP 5. Cover the pan with foil and bake for 15 minutes. Remove the foil and return the casserole to the oven for another 10 minutes to brown the cheese.

Sprinkle with more parmesan and parsley before serving, if desired. The parsley adds the perfect touch of freshness to the creamy chicken casserole!

Serve it up with a side of riced cauliflower!
