Variations For Chicken Broccoli Cheese Casserole

Shred chicken– Instead of adding diced chicken, use whole chicken breasts. Prior to serving, shred it.

Chicken broccoli rice casserole– Don’t add uncooked rice, it will become very soggy during the long cook time. It’s best to serve this casserole over steamed rice instead.

Chicken and broccoli bake– Remove the chicken and broccoli from the crockpot and spread it in a casserole dish. Then, broil in the oven for 5 minutes until cheese is golden brown.

Make it healthier– Use low-fat cheeses and low-fat soups.

Try a combination of soups– You can use cream of chicken and cream of mushroom, or whatever cream soup you prefer.

Add bacon– Add crumbled bacon topping for a smoky addition.

Ranch cheesy chicken and broccoli casserole– Add a packet of dry ranch seasoning, and omit the other seasonings.

Make it spicy– Add red chili flakes or even a can of green chilies.

Add seasonings- Such as Mexican, Italian, Cajun, or Greek seasoning.

Add other cheeses– Such as Asiago, Parmesan, white cheddar, or provolone.

Add other vegetables– Such as a bag of frozen mixed veggies.

Tips And Techniques

Frozen broccoli vs. Fresh broccoli– Either can be used, but I highly recommend fresh because they don’t release as much water during cooking.

Add the Ritz cracker topping at the end– Don’t add it in the beginning or it will steam and become a soggy mess.

How to know when casserole is done? It’s done with broccoli is tender and chicken is cooked through and cheese is melted.

Adjust seasonings– Add more or less according to your preference.

What cut of chicken to use? I used cubed chicken breast for this recipe, but you can use boneless thighs if you prefer.

Spread ingredients evenly– Do not mix layers. This ensures that everything cooks evenly and doesn’t burn.

Add ingredients in the order listed– This also ensures that they cook properly and fully.

Use full fat cheeses- For maximum richness and creaminess.

Refrigerate– In a sealed container for up to 3 days.

Freeze– I do not recommend freezing because the dairy in this casserole will separate upon thawing.
