Ingredients
- 4 cups Chopped Cauliflower Florets (or riced cauliflower, thawed)
- 2 cups Cooked Shredded Chicken (rotisserie chicken is recommended)
- 8 oz Cream Cheese, softened
- ½ cup Heavy Cream (or half-and-half)
- ¼ cup Buffalo Hot Sauce (adjust to desired heat)
- 1 tsp Dry Ranch Seasoning Mix (Hidden Valley or homemade)
- 1 cup Shredded Monterey Jack or White Cheddar Cheese, divided
- ½ cup Crumbled Blue Cheese (optional, for topping)
- Salt and Black Pepper, to taste
Instructions (Step-by-Step)
- Prep Oven and Cauliflower: Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. If using large florets, roughly chop them further.
- Make Cream Sauce: In a large mixing bowl, combine the softened cream cheese, heavy cream, Buffalo hot sauce, and dry Ranch seasoning mix. Use an electric mixer or whisk to beat until the mixture is completely smooth and velvety.
- Assemble Filling: Add the shredded chicken, chopped cauliflower, and ½ cup of the shredded Monterey Jack cheese to the cream sauce mixture. Stir well to ensure all the cauliflower and chicken are coated.
- Bake: Transfer the mixture to the prepared baking dish and spread into an even layer. Top with the remaining shredded cheese (Monterey Jack/Cheddar).
- Cook and Finish: Bake for 25–30 minutes, or until the casserole is bubbling hot and the topping is melted and golden. If using, sprinkle the crumbled blue cheese over the top during the last 5 minutes of baking.
- Serve: Let the casserole rest for 5 minutes before serving.
Storage and Expert Tips
- Cauliflower Prep: If using frozen cauliflower, thaw it completely and blot it dry with paper towels. Excess water will make the casserole watery. If using fresh, blanch the florets for 2 minutes to soften them before adding to the mix.
- Cream Cheese Temper: Ensure the cream cheese is fully softened before mixing the sauce to guarantee a smooth, lump-free binder.
- Shredding Hack: Using a hand mixer to shred the cooked rotisserie chicken makes prep incredibly fast.
- Spice Balance: The tang of the blue cheese or a dollop of sour cream added at the end is essential for balancing the richness of the cream cheese and the spice of the Buffalo sauce.
Variations
- Broccoli Base: Substitute the cauliflower with chopped broccoli florets.
- Crunchy Topping: Mix Panko breadcrumbs with melted butter and sprinkle over the cheese before baking for an added textural element (optional, not strictly keto).
- Vegetable Boost: Sauté diced celery and onions and mix them into the sauce with the chicken.
Serving Suggestions
- Sides: Celery sticks and carrot sticks for dipping.
- Cooling Toppings: Sour cream, fresh chives, and a side salad.
Frequently Asked Questions
Q: Can I use fresh chicken breast cubes instead of shredded cooked chicken? A: No. The casserole only bakes for 25–30 minutes, which is not enough time to cook raw chicken safely. You must use pre-cooked, shredded chicken for this easy keto casserole.
Q: Why does the recipe use both cream cheese and heavy cream? A: Cream cheese provides tang and acts as the primary binder for the casserole (preventing it from running). Heavy cream adds the necessary liquid volume and richness to coat the cauliflower and chicken evenly.
Q: Can I freeze this buffalo chicken cauliflower casserole? A: Yes. Assemble the casserole completely, cover it tightly with foil, and freeze for up to 3 months. Thaw overnight in the refrigerator and bake as directed (adding 10–15 minutes).
Q: How do I make the spice level milder for kids? A: Use a very mild hot sauce (like the original Frank’s RedHot) and omit the dry Ranch seasoning mix, as the Ranch mix contains a lot of black pepper and spice.
