Keto Chicken Alfredo Casserole

Ingredients You’ll Need

For the Chicken Filling:

  • 2 cups cooked chicken (shredded or cubed; rotisserie chicken works great for time-saving)
  • 1 cup broccoli florets (fresh or frozen, if using frozen, thaw first)
  • 1 cup cauliflower florets (fresh or frozen)

For the Alfredo Sauce:

  • 1/2 cup unsalted butter
  • 2 cups heavy cream
  • 2 cups shredded mozzarella cheese (plus more for topping)
  • 1/2 cup grated Parmesan cheese
  • 2 cloves garlic (minced)
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste

For Topping:

  • 1/2 cup shredded mozzarella cheese
  • Fresh parsley (for garnish)

When choosing your ingredients, opt for fresh vegetables where possible, and select high-quality cheeses for the best flavor. If you’re dairy-free, consider coconut cream or a non-dairy cheese substitute that melts well.

How to make Keto Chicken Alfredo Casserole

Step 1: Preheat your oven to 350°F (175°C).

Step 2: In a medium saucepan over medium heat, melt the butter. Add the minced garlic and sauté for about 1 minute, until fragrant.

Step 3: Pour in the heavy cream, stirring constantly. Allow it to simmer for about 5 minutes, then gradually add the mozzarella and Parmesan cheese. Stir until smooth and creamy, then season with Italian seasoning, salt, and pepper.

Step 4: In a large mixing bowl, combine the cooked chicken, broccoli, and cauliflower. Pour the creamy Alfredo sauce over the top and mix well to combine.

Step 5: Transfer the mixture into a greased 9×13 inch baking dish. Sprinkle the remaining mozzarella cheese on top.

Step 6: Bake in the preheated oven for about 25–30 minutes, or until the top is golden and bubbly. You can broil for the last 2-3 minutes to achieve a nice crust.

Step 7: Remove the casserole from the oven and let it rest for about 5 minutes before serving. Garnish with chopped fresh parsley.

The creamy texture should be inviting, and a golden top signals it’s ready to be enjoyed.

Expert Tips & Ideas

  • For added flavor, consider incorporating cooked bacon bits or sautéed mushrooms into the chicken filling.
  • For a spicier kick, add red pepper flakes or Italian sausage instead of chicken.
  • Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave.
  • Freezing: This casserole freezes beautifully. Just wrap tightly and seal, then freeze for up to 3 months. Thaw before reheating in the oven until warmed through.

Best Ways to Serve

This Keto Chicken Alfredo Casserole is wonderfully versatile. For a complete meal, pair it with a side salad featuring fresh greens and light vinaigrette, or serve with zucchini noodles for a low-carb alternative to pasta. A glass of white wine or sparkling water makes for a refreshing accompaniment.

To elevate the presentation, serve the casserole in individual portions, garnished with a sprinkle of fresh parsley for a splash of color.

Common Questions

Can I make this recipe ahead of time?

Absolutely! You can prepare the casserole, cover it, and refrigerate it up to a day before baking. Just add a few minutes to the baking time if it’s going in the oven cold.

Can I freeze the leftovers?

Yes, this casserole freezes well. Allow it to cool completely, then store in an airtight container. Reheat in the oven or microwave until warmed through.

What can I use instead of heavy cream?

Coconut cream is a great substitute for a dairy-free version, but you may need to adjust the seasoning for taste.

How do I prevent the dish from becoming watery?

Make sure to use thoroughly drained vegetables and avoid adding too much extra liquid in the sauce. Cooking the casserole to achieve a nice bubbly top also helps.

Can I make this vegetarian or dairy-free?

For vegetarian options, swap the chicken for a mix of hearty vegetables such as mushrooms, zucchini, or bell peppers, and use a dairy-free cheese alternative.
