It’s rich and cheesy with just the right heat, but still low in carbs and simple to make on a weeknight. You’ll get tender chicken, cozy cauliflower, and a silky sauce that clings to every bite.
This is the kind of casserole that makes eating low-carb feel like no sacrifice at all. Bonus: it reheats beautifully, so leftovers make an easy lunch.
Ingredients
Method
- Prep the oven and dish: Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
- Par-cook the cauliflower: Steam or microwave the florets until just fork-tender, about 4–6 minutes. Drain well and pat dry with paper towels. Removing excess moisture helps prevent a watery bake.
- Warm the buffalo chicken: In a large bowl, toss the shredded chicken with half the buffalo sauce (1/2 cup). Set aside.
- Make the Alfredo base: In a medium saucepan over medium heat, melt the butter. Stir in the heavy cream and bring to a gentle simmer.
- Whisk in cheeses: Add the cream cheese and whisk until smooth. Stir in Parmesan until melted and the sauce is velvety.
- Season the sauce: Add garlic powder, onion powder, smoked paprika (if using), and a pinch of salt and pepper. Taste and adjust. You want it slightly salty to balance the cauliflower.
- Buffalo meets Alfredo: Stir the remaining 1/2 cup buffalo sauce into the Alfredo. The sauce should be creamy-orange and pourable. If it’s too thick, splash in a tablespoon or two of cream.
- Combine the bake: In a large mixing bowl, combine the cauliflower, buffalo chicken, and half of the mozzarella. Pour the buffalo Alfredo sauce over the top and fold gently to coat everything.
- Spread and top: Transfer the mixture to the prepared baking dish. Sprinkle the remaining mozzarella evenly over the surface.
- Bake: Bake for 18–22 minutes until bubbling at the edges and the cheese is melted.
- Broil for color (optional): Broil 1–2 minutes to brown the top slightly. Watch closely.
- Rest and garnish: Let the casserole rest 5–10 minutes to set. Garnish with parsley or chives and a few blue cheese crumbles, if you like.
- Serve: Scoop into bowls and enjoy as is, or with a crisp side salad.
What Makes This Recipe So Good
- Big flavor, minimal fuss: Rotisserie chicken and a quick stovetop sauce make this dinner weeknight-friendly.
- Keto without compromise: Cauliflower stands in for pasta, but the textures and flavors still hit that comfort-food sweet spot.
- Creamy heat balance: The Alfredo brings richness while buffalo sauce brings a clean, tangy spice—neither overwhelms.
- Customizable: Dial up the spice, swap cheeses, or add low-carb veggies without breaking the recipe.
- Great for meal prep: Holds up well in the fridge and reheats without getting watery when prepared as directed.

Keeping It Fresh
- Refrigeration: Store leftovers in an airtight container for up to 4 days. The flavors deepen by day two.
- Reheating: Warm in a 300°F (150°C) oven, covered, for 12–15 minutes, or microwave gently at 60% power. If it looks dry, add a splash of cream before reheating.
- Freezing: Freeze tightly wrapped portions for up to 2 months.
Thaw overnight in the fridge, then reheat in the oven. Note: the cauliflower stays best in texture if you undercook it slightly before freezing.
Why This is Good for You
- Low in carbs: Cauliflower keeps the total carbs down while providing fiber and volume.
- Protein-packed: Chicken delivers satisfying protein to keep you full.
- High in healthy fats: The sauce adds fat, helping with satiety and supporting ketosis when eaten as part of a balanced low-carb plan.
- Custom spice control: You can adjust the buffalo heat to fit your taste and tolerance, which may help you stick with your goals.
What Not to Do
- Don’t skip drying the cauliflower: Excess moisture will water down the sauce and make the bake soupy.
- Don’t overbake: Too long in the oven and the sauce can break or get greasy. Pull it when it bubbles.
- Don’t use pre-shredded cheese without checking labels: Many contain starches that add carbs and can make the sauce grainy.
- Don’t oversalt early: Parmesan and buffalo sauce are salty.
Taste before adding extra salt.
Recipe Variations
- Ranch twist: Swap 1/4 cup of the heavy cream for ranch dressing, or add 1 tablespoon ranch seasoning to the sauce.
- Bacon boost: Stir in 1/2 cup cooked, crumbled bacon before baking for smoky crunch.
- Veggie add-ins: Fold in sautéed spinach, zucchini ribbons (well-drained), or riced cauliflower for a different texture.
- Cheese swap: Use a mix of mozzarella and provolone for extra melt, or add a handful of sharp cheddar for tang.
- Spice level: Add cayenne or crushed red pepper to the sauce, or drizzle extra buffalo sauce on top before serving.
- Dairy-light option: Use half the Parmesan and mozzarella, and add an extra ounce of cream cheese to keep the sauce creamy with fewer overall cheeses.
FAQ
Is this recipe very spicy?
It has a medium kick with 1 cup of buffalo sauce. For mild heat, start with 1/2 to 3/4 cup and add more to taste. You can also balance spice by topping servings with a dollop of sour cream or a sprinkle of blue cheese.
Can I use frozen cauliflower?
Yes, but thaw completely and drain well.
Pat dry and even squeeze gently in a clean towel. Cook it just until tender, not mushy, to protect the texture in the bake.
What chicken works best?
Leftover roasted chicken or store-bought rotisserie is ideal. You can also poach chicken breasts or thighs, then shred.
Thigh meat adds extra juiciness.
How many carbs per serving?
Exact counts vary by brands and portion size, but a typical serving of this bake usually lands around 5–8 net carbs. For precision, plug your specific ingredients into a nutrition calculator.
Can I make it ahead?
Yes. Assemble the casserole up to the point of baking.
Cover and chill for up to 24 hours, then bake. You may need to add 5–10 extra minutes since it will be cold going into the oven.
What can I use instead of buffalo sauce?
Try a mix of hot sauce with melted butter and a splash of white vinegar. For a different profile, use a smoky chipotle hot sauce blended into the Alfredo.
Why did my sauce separate?
Overheating can cause the fats to split.
Keep the sauce at a gentle simmer, not a hard boil, and avoid overbaking. If it starts to break, whisk in a splash of cream off heat to bring it back together.
Can I make it without cream cheese?
Yes. Increase Parmesan by 1/2 cup and simmer the cream a few extra minutes to reduce and thicken.
The texture will be slightly less plush but still delicious.
