Essential Ingredients for Chicken & Cauliflower Casserole

This hearty and cheesy keto casserole comes together with a handful of simple, low-carb ingredients.

• Chicken: 1.5 lbs (about 700g) boneless, skinless chicken thighs, cut into bite-sized pieces
• Cauliflower: 1 large head of cauliflower, cut into florets
• For the Creamy Cheese Sauce:
  • 4 oz (½ block) cream cheese, softened
  • ½ cup heavy cream
  • 1 cup low-sodium chicken broth
  • 2 cups shredded sharp cheddar cheese
• Aromatics: 1 teaspoon garlic powder & ½ teaspoon onion powder
• Fat: 2 tablespoons olive oil
• Seasoning: Salt and black pepper to taste

Ingredients Notes

A little more detail on our key ingredients will ensure your keto casserole is a spectacular success.

• The Chicken Thighs: For the most flavourful and juicy result, this recipe uses boneless, skinless chicken thighs. Their naturally higher fat content ensures they stay incredibly moist and tender as they bake, which is perfect for a satisfying keto dish. Cutting the thighs into uniform, bite-sized pieces helps them to cook evenly and quickly.
• The Cauliflower: Using a fresh head of cauliflower and cutting it into bite-sized florets is the best choice for this recipe. As we’ll discuss in the instructions, taking the extra step to roast the cauliflower first is the key to a perfect, non-watery casserole with a deep, delicious flavour.
• The Cheese Sauce: Our simple, homemade cheese sauce is what makes this casserole so incredibly rich and satisfying. Using a base of full-fat cream cheese and heavy cream is essential for a thick, creamy, and stable sauce that is perfectly keto-friendly. A good quality, sharp cheddar cheese will provide the best and boldest flavour.
• The Cheese: A sharp cheddar cheese will give your sauce the most classic, savory, and delicious flavour. For the absolute creamiest and smoothest melt with no added starches, it is always best to buy a block of cheese and shred it yourself just before using.

How to Make a Cheesy Chicken Thigh & Cauliflower Bake

Let’s walk through the simple steps to create this ultimate low-carb comfort food dinner.

• Step 1: Prepare the Oven and Roast the Cauliflower. First, preheat your oven to a hot 200°C (400°F). On a large, rimmed baking sheet, toss your cauliflower florets with 1 tablespoon of the olive oil, salt, and pepper. Roast for 15-20 minutes, until the cauliflower is tender and lightly browned on the edges.
• Step 2: Cook the Chicken. While the cauliflower is roasting, heat the remaining 1 tablespoon of olive oil in a large, oven-safe skillet over medium-high heat. Season your bite-sized chicken pieces with salt and pepper and cook them for 5-7 minutes, until they are browned and cooked through.
• Step 3: Create the Creamy Cheese Sauce. Reduce the heat to low. Add the softened cream cheese and the heavy cream to the skillet with the cooked chicken. Stir until the cream cheese has melted into a smooth, creamy sauce.
• Step 4: Combine the Casserole. Gently stir the roasted cauliflower into the skillet with the creamy chicken. Stir in the chicken broth, the garlic powder, and the onion powder.
• Step 5: Add Cheese and Bake. Stir in 1 ½ cups of the shredded cheddar cheese until it has melted and the sauce is thick and gooey. Sprinkle the remaining ½ cup of cheese evenly over the top of the skillet.
• Step 6: Bake to Bubbly Perfection. Transfer the entire oven-safe skillet to the oven and bake for 10-15 minutes. The casserole is done when the sauce is hot and bubbly and the cheese on top is completely melted and slightly golden. Serve hot.

Storage Options

This keto-friendly casserole makes for fantastic leftovers and is great for meal prepping. Once the casserole has cooled completely, you can store it in an airtight container in the refrigerator for up to 4 days. It can be easily reheated in the microwave for a quick and satisfying low-carb lunch or dinner.

Variations and Substitutions

This versatile low-carb recipe is a wonderful template that you can easily adapt to your tastes. For some extra savory flavour, you can add some cooked and crumbled bacon to the casserole along with the cheese. You can also add other low-carb vegetables to the mix, such as sautéed mushrooms or some fresh baby spinach stirred in at the end. For a bit of a spicy kick, feel free to use a Pepper Jack cheese instead of the cheddar.

Practical & Valuable Tips

For the absolute best flavour and texture, do not skip the initial step of roasting your cauliflower; this prevents a watery casserole and adds a wonderful, nutty sweetness to the dish. Using an oven-safe skillet, like a cast-iron pan, allows you to make this entire meal in one single dish, which makes the cleanup incredibly easy. Finally, for the creamiest sauce, always use full-fat cream cheese and heavy cream, and be sure to shred your own cheese from a block.

Frequently Asked Questions

1. My casserole turned out watery. What did I do wrong? A watery cauliflower casserole is almost always because the cauliflower was not pre-roasted first. Raw cauliflower holds a lot of moisture that it will release as it bakes, which will thin out your beautiful cheese sauce. Roasting it first is the key to preventing this.
2. Can I use chicken breasts instead of chicken thighs? Yes, you can absolutely use boneless, skinless chicken breasts. They are a leaner option, so just be careful not to overcook them in the skillet in the first step to ensure they stay nice and juicy in the final casserole.
3. Can I use frozen cauliflower for this recipe? You can, but it is very important that you roast it first, just like the fresh cauliflower. Roasting the frozen florets from frozen will help to cook off a lot of their excess moisture and prevent your casserole from becoming watery.
4. Can I assemble this casserole ahead of time? Yes, this is a great make-ahead meal! You can fully assemble the entire casserole in your oven-safe skillet or a baking dish, cover it, and store it in the refrigerator for up to 24 hours. You may just need to add an extra 10 to 15 minutes to the baking time since you are starting with a cold dish.
5. What other cheeses are good in this keto casserole? While sharp cheddar is a classic choice, this casserole is fantastic with a variety of good melting cheeses. A nutty Gruyère, a simple Monterey Jack, or even a blend of Italian cheeses would all be delicious.
