Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Casserole Base:

• 4 tablespoons unsalted butter
• 1 large yellow onion, finely diced (about 1 cup)
• 4 teaspoons fresh garlic, minced
• ⅓ cup all-purpose flour
• 2 cups chicken broth
• 2 cups whole milk, at room temperature

Main Filling:

• 4 cups fresh broccoli florets
• 2 cups rotisserie chicken, finely shredded
• 2½ cups sharp cheddar cheese, freshly shredded

Seasonings:

• 1 teaspoon kosher salt
• 1 teaspoon freshly ground black pepper
• ½ teaspoon cayenne pepper (adjust to taste)

Biscuit Topping:

• 1 can refrigerated buttermilk biscuits (6 count) or homemade biscuits

Garlic Butter Finish:

• 4 tablespoons butter, melted
• 1 teaspoon kosher salt
• 2 teaspoons fresh garlic, minced
• 1 tablespoon fresh parsley, minced

Directions

1. Prepare the Casserole Base: Preheat your oven to 375°F (190°C). In a large saucepan, melt the butter over medium heat. Add the diced onion and minced garlic, and sauté for about 4-5 minutes until the onion is soft and translucent. Stir in the flour and cook for another 1-2 minutes to form a roux.
2. Make the Sauce: Gradually whisk in the chicken broth and whole milk, stirring constantly to prevent lumps. Bring the mixture to a simmer and cook for about 5-7 minutes until it thickens to a creamy consistency. Season with salt, pepper, and cayenne pepper. Remove from heat and set aside.
3. Prepare the Filling: In a large mixing bowl, combine the fresh broccoli florets, shredded rotisserie chicken, and sharp cheddar cheese. Pour the creamy sauce over the mixture and stir to combine everything thoroughly.
4. Assemble the Casserole: Transfer the broccoli, chicken, and cheese mixture into a greased 9×13-inch casserole dish. Arrange the biscuits (either canned or homemade) on top of the casserole, placing them evenly across the surface.
5. Bake the Casserole: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the biscuits are golden brown and cooked through, and the filling is bubbling around the edges.
6. Prepare the Garlic Butter Finish: While the casserole is baking, mix together the melted butter, salt, minced garlic, and fresh parsley in a small bowl.
7. Finish the Casserole: Once the casserole is out of the oven, immediately brush the biscuits with the garlic butter mixture to add a delicious, savory finish. Let the casserole rest for 5 minutes before serving.

FAQs

1. Can I make this casserole ahead of time?

Yes, you can prepare the casserole base and filling ahead of time, and store it in the refrigerator. When ready to bake, top with the biscuits and proceed with baking.

2. Can I use frozen broccoli instead of fresh?

Yes, frozen broccoli can be used in place of fresh. Just make sure to thaw and drain it well before adding it to the casserole to avoid excess moisture.

3. Can I use a different type of biscuit for the topping?

Absolutely! If you prefer homemade biscuits, you can use your favorite recipe. Alternatively, you could also use a biscuit mix or even crescent roll dough for a different texture.

4. Can I use a different type of chicken?

If you don’t have rotisserie chicken, you can use cooked, shredded chicken breast or thighs from scratch. Leftover chicken or turkey would also work great.

5. Can I make this dish without the garlic butter finish?

Yes, the casserole is still delicious without the garlic butter topping, but it adds an extra layer of flavor and richness to the dish.

6. How can I make this casserole spicier?

To increase the spice, add more cayenne pepper or mix in some chopped jalapeños or hot sauce to the filling. You can also use a spicier cheese, such as pepper jack.

7. Can I freeze the casserole?

Yes, you can freeze the casserole before baking. Just assemble it as directed, cover tightly with plastic wrap and aluminum foil, and freeze for up to 2-3 months. To bake, let it thaw in the refrigerator overnight and then bake as usual.

8. How can I make sure the biscuits cook all the way through?

Ensure that your biscuits are evenly spaced and allow them to cook for the full recommended time. If you’re concerned, you can loosely cover the casserole with foil for the first 15 minutes of baking to prevent over-browning.

9. Can I make this casserole dairy-free?

Yes, you can substitute dairy ingredients with non-dairy alternatives. Use plant-based butter, almond milk or oat milk, and dairy-free cheese. You may also need to find a dairy-free biscuit option.

10. Can I add more cheese to the filling?

Definitely! If you love cheesy casseroles, feel free to add extra cheese to the filling. Just make sure the cheese melts into the sauce for a smooth and creamy texture.
