Ingredients

  • Cooked chicken, shredded or diced: About 2 cups of tender, cooked chicken provides protein and a hearty base for the casserole.
  • Broccoli florets, steamed: 2 cups of fresh broccoli steamed until just tender to keep color and nutrients intact.
  • Heavy cream: 1 cup of full-fat cream adds rich, creamy texture and depth of flavor.
  • Shredded cheddar cheese: 1 cup of sharp cheddar cheese melts beautifully, giving the casserole its cheesy top and savory taste.
  • Cream cheese, softened: 1/2 cup cream cheese gives the sauce a smooth, velvety consistency and tangy richness.
  • Garlic powder: 1 teaspoon adds subtle aromatic undertones that complement the cheese and chicken perfectly.
  • Salt and pepper: To taste, seasoning enhances all the flavors harmoniously.
  • Paprika (optional): 1/2 teaspoon for a mild smoky flavor and vibrant color boost.

Instructions

Preheat the oven

Set your oven to 350°F (175°C) to ensure it reaches the perfect temperature by the time your casserole is ready to bake. This moderate heat helps cook the casserole evenly without drying it out.

Make the creamy sauce

In a large mixing bowl, whisk together the heavy cream, softened cream cheese, garlic powder, salt, pepper, and optional paprika. Mixing until smooth creates a luscious base that clings to the chicken and broccoli.

Combine chicken and broccoli

Add the shredded chicken and steamed broccoli to the creamy sauce. Stir gently to coat everything well, ensuring every bite is infused with flavor and richness.

Prepare the baking dish

Grease a 9×13-inch baking dish lightly to prevent sticking. Then transfer the coated chicken and broccoli mixture evenly into the dish, spreading it smoothly for even baking.

Add cheddar cheese topping

Sprinkle the shredded cheddar cheese evenly over the mixture’s surface. This forms a golden, bubbly, and savory crust during baking that enhances flavor and texture.

Bake until bubbly

Place the dish in the preheated oven and bake for 25-30 minutes. The casserole should be hot, with melted cheese bubbling on top, indicating a perfectly cooked creamy center.

Cool before serving

Let the casserole cool for a few minutes after baking to allow it to set slightly. This makes serving easier and lets the flavors meld wonderfully before enjoying.

You Must Know

  • Steaming the broccoli just until tender preserves nutrients and prevents it from becoming mushy in the casserole.
  • You can swap cheddar for your preferred melty cheeses like mozzarella or gouda to vary flavor.
  • Using cooked chicken saves time — rotisserie chicken works perfectly for this dish.

Storage Tips

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, warm in the oven or microwave until hot and bubbly for best texture.

Serving Suggestions

Serve this casserole hot with a fresh green salad or cauliflower rice to keep the meal low carb and balanced. It also pairs well with a crisp keto-friendly pickle or steamed veggies.

Professional Tips

  • For extra flavor, sauté minced garlic in butter before mixing with the cream for a deeper garlic taste.
  • Ensure the cheeses are at room temperature for easier blending and smoother sauce consistency.
  • Let the casserole rest after baking to set, which helps with cleaner serving portions.

FAQs

Can I use raw chicken for this casserole?

This recipe requires cooked chicken, so raw chicken must be cooked first to prevent undercooking and ensure food safety.

Is this casserole freezer-friendly?

Yes, you can freeze it before baking. Wrap tightly and freeze up to 2 months, then bake from frozen adding extra baking time.

Can I substitute broccoli with other vegetables?

Absolutely! Cauliflower or green beans work well as a low-carb alternative if you want a different veggie texture.

What can I use instead of heavy cream?

Full-fat coconut milk or sour cream can be alternatives, but the texture and taste will slightly differ from the original.

How can I make it spicier?

Add chili flakes, cayenne pepper, or a bit of diced jalapeño to the sauce for a spicy kick while maintaining the keto profile.
