Ingredients for Chicken Biscuit Casserole

• Cooked chicken: Slice the chicken into cubes for this chicken and biscuit casserole. You can use breasts, thighs or a combination of the two.
• Cream of chicken soup: This savory condensed soup is part of the creamy sauce and gives the dish more flavor in general. Use canned or homemade cream of chicken soup.
• Mayonnaise: Use regular, olive oil or avocado oil mayonnaise here. Avoid light or nonfat mayos as they won’t create the right texture in the sauce.
• Cheddar cheese: Sprinkle shredded cheddar cheese into the dish before baking for a bubbly and cheesy chicken and biscuits casserole.
• Buttermilk biscuits: Canned buttermilk biscuits are so convenient here. You can also use frozen biscuits (thaw them first) or your own homemade biscuits.
• Broccoli: Briefly cook the broccoli before chopping and adding it to this dish. Or, pick up some frozen chopped broccoli—thawed and drained, it’ll be tender enough to go straight in.
• Onion: Of all the types of onions, red, yellow or white varieties are fine to use here. Finely dice them for this chicken biscuit bake—you’ll need about 1 cup.
• Eggs: You’ll need two large eggs for the sauce that goes over the biscuits. It’ll make the top of the biscuits crispy and golden.
• Sour cream: Blend sour cream with the eggs to make a sauce to cover the biscuits.
• Worcestershire sauce: Just a little Worcestershire adds a dose of salty, umami flavor to the chicken and biscuit casserole. Worcestershire sauce is meant to enhance the recipe flavors, not overwhelm them. If you’d like a more mild flavor, reduce the amount called for by half.
• Seasonings: Celery seed and salt flavor the topping of this chicken and biscuits casserole.

Directions

Step 1: Combine the casserole ingredients

Preheat the oven to 375°F and have ready a greased 13×9-inch baking dish.

Blend together the cream soup, mayonnaise and Worcestershire sauce in a large bowl. Stir in the cubed chicken, chopped broccoli and diced onion.

Spoon the chicken-sauce mixture into the prepared baking dish, and sprinkle shredded cheddar cheese evenly over the top. Cover the dish and bake it for 20 minutes.

Step 2: Add the biscuits

Separate the canned biscuits and split each one in half. Pull the casserole from the oven. Place the biscuits, cut side down, over the top of the casserole.

Step 3: Top with the sauce and bake

Whisk together the eggs, sour cream, celery seed and salt in a small bowl. Spoon this sauce over the tops of the biscuits.

Put the casserole back in the oven, uncovered, for another 28 to 32 minutes. It’s finished when the biscuits are golden brown and baked.

Recipe Variations

• Add other veggies: Not a fan of broccoli? Substitute other cooked veggies like peas, carrots, diced bell peppers or corn.
• Try a different soup: Other condensed cream soups, like mushroom, celery or cheddar will be equally delicious in this chicken and biscuit casserole.
• Change the spices: If you’re not a fan of celery seed, use other spices in its place, like lemon pepper, curry powder, Italian spice blend, dried parsley, garlic powder or dried thyme.
