- Assemble: Spread the mixture evenly in the baking dish.Top with the remaining cheese.

- Freezer: Portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge.

For a full pan, cover with foil and warm at 325°F (165°C) for 15–20 minutes.

Health Benefits
- High protein, balanced carbs: Chicken and Greek yogurt provide steady energy and satiety without a blood sugar spike.
- Lighter fats, big flavor: Using yogurt and light cream cheese keeps calories in check while maintaining creaminess.
- Veggie density: Cauliflower rice and celery bring fiber, vitamins, and volume for a filling meal with fewer calories.
- Custom sodium control: Choosing low-sodium broth and adjusting buffalo sauce helps manage salt intake.
Pitfalls to Watch Out For
- Watery casserole: Skip this by cooking moisture out of the cauliflower rice and draining any excess liquid before assembly.
- Over-salting: Many hot sauces and cheeses are salty.
Taste the sauce before adding extra salt.
- Curdled sauce: If the yogurt overheats on the stovetop, it can separate. Keep it off direct heat and bake gently.
- Rubbery chicken: Use pre-cooked chicken that’s just done, not dry. Rotisserie chicken works well.
- Too spicy: Start with 1/2 cup buffalo sauce.
You can always drizzle more at the table.
Variations You Can Try
- Ranch twist: Stir 1–2 tbsp ranch seasoning into the sauce for a tangy, herby kick.
- Extra veg: Fold in chopped spinach or steamed broccoli florets before baking.
- No-dairy option: Use dairy-free yogurt and cream cheese, and a vegan cheese shreds topping. Check your hot sauce for butter content.
- Lower heat, more smoke: Swap paprika for smoked paprika and skip the cayenne.
- Sweet potato base: Layer thinly sliced par-cooked sweet potatoes on the bottom for a heartier casserole.
- Blue cheese lovers: Mix in 1/4 cup crumbles for a classic buffalo-and-blue combo.
- Pasta swap: Use whole-wheat or chickpea pasta instead of cauliflower rice for a higher-carb version. Cook just shy of al dente.
FAQ
Can I use canned chicken?
Yes, but drain it well and shred it before mixing.
Rotisserie or freshly cooked chicken has better texture, but canned works in a pinch.
Is this casserole gluten-free?
It can be. The base ingredients are naturally gluten-free, but always check labels on buffalo sauce, broth, and any seasonings to be sure.
How spicy is it?
With 1/2 cup buffalo sauce and no cayenne, it’s medium. Add cayenne or more hot sauce for extra heat, or cut back to 1/3 cup for mild.
What’s the best cheese to use?
Part-skim mozzarella melts smoothly, while sharp cheddar adds punchy flavor.
A 50/50 blend is a great balance.
Can I make it in a slow cooker?
Yes. Combine everything except the cheese and cook on Low for 2–3 hours, stirring once. Top with cheese, cover, and heat 10–15 more minutes until melted.
It will be saucier than the baked version.
How do I cook the chicken for this?
Poach chicken breasts in simmering salted water for 12–15 minutes, or bake at 400°F (205°C) for 18–22 minutes until 165°F (74°C). Rest, then shred.
Can I use regular rice instead of cauliflower rice?
Yes. Use 3 cups cooked brown or white rice.
Make sure it’s cooled and not soggy before mixing.
What’s a good side dish?
A crisp green salad with lemon vinaigrette, roasted green beans, or celery sticks with a light ranch dip pair nicely.
