Casserole Base
- 4 tablespoons unsalted butter
- 1 large yellow onion, finely diced (about 1 cup)
- 4 teaspoons garlic, minced
- ⅓ cup (42 g) all-purpose flour
- 2 cups (480 g) chicken broth
- 2 cups (490 g) whole milk, room temperature
- 4 cups (364 g) broccoli florets
- 1 teaspoon kosher salt
- 1 teaspoon black pepper
- 1/2 teaspoon cayenne pepper, more or less to taste
- 2 cups (140 g) large rotisserie chicken, finely shredded
- 2 1/2 cups (226 g) sharp cheddar cheese, shredded
Biscuit Topping
- 1 recipe homemade buttermilk biscuits OR canned biscuits (6 biscuits)
Garlic Butter Topping
- 4 tablespoons butter, melted
- 1 teaspoon kosher salt
- 2 teaspoons garlic, minced
- 1 tablespoon fresh parsley, minced
- Preheat Oven and Prepare Baking Dish: Preheat the oven to 375°F. Lightly butter a 13×9 inch baking dish to prevent sticking and set aside.
- Sauté Onion: In a large skillet over medium heat, melt the unsalted butter. Add the finely diced onion and cook until translucent, about 8 minutes, stirring occasionally to prevent burning.
- Add Garlic: Add the minced garlic to the skillet and cook for an additional 1 minute until fragrant.
- Create Roux: Sprinkle the all-purpose flour into the skillet and whisk continuously for about 1 minute until the mixture is lightly browned, which will thicken the sauce.
- Add Broth and Milk: Slowly pour in the chicken broth and whole milk while whisking constantly to avoid lumps. Continue whisking until smooth.
- Simmer with Broccoli and Seasonings: Add the broccoli florets, kosher salt, black pepper, and cayenne pepper into the sauce. Bring the mixture to a simmer and cook uncovered for 12-15 minutes, stirring occasionally, until the broccoli is tender.
- Prepare Biscuits: While the broccoli is cooking, open your can of biscuits or prepare homemade buttermilk biscuits as per recipe instructions.
- Add Chicken and Cheese: Once broccoli is tender, stir in the shredded rotisserie chicken and shredded cheddar cheese. Stir until the cheese melts and the mixture is well combined.
- Transfer to Baking Dish: Remove skillet from heat and transfer the creamy broccoli, chicken, and cheese mixture into the prepared 13×9 baking dish.
- Top with Biscuits: Place 6 biscuits evenly spaced on top of the casserole mixture.
- Bake: Bake the casserole in the preheated 375°F oven for 15 minutes or until the biscuits are golden brown and cooked through.
- Make Garlic Butter: While casserole bakes, combine melted butter, kosher salt, minced garlic, and fresh parsley in a small bowl to create garlic butter.
- Brush Biscuits: Remove casserole from oven and immediately brush the tops of the biscuits generously with the garlic butter mixture for added flavor and moisture.
- Serve and Enjoy: Allow casserole to cool slightly before serving. Enjoy this warming dish as a complete meal perfect for any occasion.
Notes
- You can use homemade buttermilk biscuits or good-quality canned biscuits depending on time and preference.
- Adjust the cayenne pepper to your desired heat level or omit if you prefer no spice.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven.
- For a lower-fat version, substitute whole milk with 2% milk and use reduced-fat cheddar cheese.
- Make sure to stir the sauce thoroughly when adding broth and milk to prevent lumps from forming in the roux.
