How to Make Creamy Chicken and Cauliflower Rice Casserole

Let me show you how incredibly easy it is to make this Creamy Chicken and Cauliflower Rice Casserole:

Prep Chicken, Cauli Rice & Oven

1. First, I preheat my oven to 400ºF (200°C). I lightly spray a 9x13-inch baking pan with cooking spray and set it aside.
2. I remove the skin from the rotisserie chicken (and discard it). Then, I remove the meat from the bones and shred or chop it. I need about 4 cups.
3. Next, I cook the cauliflower rice. I place the riced cauliflower in a microwave-safe bowl with about ¼ cup of water. I cook it in the microwave for about 7 minutes, or until tender-crisp. I let it cool down for a couple of minutes and then carefully drain any excess water. Ensuring the cauliflower rice isn't too wet is important for the casserole's consistency.

Combine Ingredients

1. In a large bowl, I combine the chopped rotisserie chicken, cooked and drained cauliflower rice, heavy cream, softened cream cheese, finely minced onion (or onion powder), minced garlic (or garlic powder), black pepper, smoked paprika, and chicken stock.
2. I stir everything together until it's well combined.

Assemble and Bake

1. I pour the chicken and cauliflower rice mixture into the prepared 9x13 inch baking pan and spread it out evenly.
2. I top the mixture evenly with the shredded cheddar cheese (or Parmesan).
3. I bake the casserole uncovered for 20 minutes, or until heated through and the cheese is melted and bubbly.

Rest, Garnish, and Serve

1. I allow the casserole to rest for 5 minutes after removing it from the oven. This helps the sauce thicken slightly.
2. I garnish with fresh chopped parsley if desired.
3. Serve warm

Tips and Tricks for the BEST Keto Casserole

Here are my secrets for making this Chicken Cauliflower Rice Casserole truly exceptional:

• Use Rotisserie Chicken: This is a huge time-saver and adds great flavor. Leftover cooked chicken also works perfectly.
• Drain Cauliflower Rice Well: Whether you steam it in the microwave or use pre-cooked frozen, make sure the cauliflower rice is well-drained to avoid a watery casserole.
• Room Temperature Cream Cheese: Softened cream cheese blends much more smoothly into the mixture.
• Freshly Shredded Cheese: Melts better and tastes superior to pre-shredded cheese which often contains anti-caking agents.
• Don't Overbake: Bake just until heated through and the cheese is melted and bubbly.

How to Serve

This Creamy Chicken and Cauliflower Rice Casserole is a fantastic low-carb meal on its own! Serve it hot, garnished with:

• Fresh chopped parsley or green onions
• Extra shredded cheese
• Crumbled bacon bits (optional)
• A dash of hot sauce (optional)

It also pairs well with:

• A simple green side salad
• Steamed green beans or asparagus

Make Ahead and Storage

This casserole is great for making ahead!

• Make Ahead: You can fully assemble the casserole (without baking) up to 24 hours in advance. Cover tightly and store in the refrigerator. You may need to add 5-10 minutes to the baking time when baking from cold.
• Storage: Store leftover baked casserole in an airtight container in the refrigerator for up to 3-4 days.
• Reheating: Reheat individual portions gently in the microwave or cover the pan with foil and reheat in a 350°F (175°C) oven until warmed through.

FAQs about Creamy Chicken and Cauliflower Rice Casserole

• Can I use frozen cauliflower rice?
  • Yes! Cook the frozen cauliflower rice according to package directions (usually microwaving or steaming) and make sure to drain it very well before adding it to the casserole mixture.
• Can I use different cheese?
  • Absolutely! Monterey Jack, Colby, Gruyere, or even a spicy Pepper Jack would be delicious substitutes or additions.
• Can I freeze this casserole?
  • Yes, this casserole freezes reasonably well. Bake and cool completely, then cover tightly or transfer to freezer-safe containers. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. The texture might be slightly different after freezing.
