How to Make High Protein Buffalo Chicken Casserole

1. Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish.
2. In a large skillet, heat olive oil over medium heat. Add the onion and sauté until soft and translucent, about 3-4 minutes. Add garlic and cook for 30 seconds more until fragrant.
3. Stir in the cauliflower rice and cook for 3-5 minutes until it’s just tender. This adds texture and keeps the casserole light.
4. In a large bowl, whisk together 1/2 cup buffalo sauce, chicken broth, cream cheese, and Greek yogurt until smooth. This is your creamy, protein-rich backbone.
5. Fold in the shredded chicken, sautéed onions and garlic, cauliflower rice, salt, and pepper. Mix until everything is evenly coated with the sauce.
6. Pour the mixture into the prepared baking dish. Sprinkle cheddar and mozzarella evenly over the top. If you want extra texture, scatter crushed tortilla chips over the cheese.
7. Bake for 20-25 minutes, until the cheese is melted and bubbling and the sauce is slightly thickened. If you like a crisper top, broil for an additional 1-2 minutes, watching closely to prevent burning.
8. Let rest for 5 minutes before serving. Garnish with green onions or blue cheese crumbles if desired. Serve hot.

Optional Variations

Spice Level Where You Want It

Skip the extra heat or dial it up. Swap hot buffalo sauce for mild if you’re feeding kids, or mix with a teaspoon of chili paste for a bright punch.

Lower-Carb Twist

Omit the tortilla chips to keep it lower in carbs. You’ll lose a bit of crunch, but you gain a smoother bite and more protein density per portion.

Cheesy Upgrades

Increase the cheese to 1 cup each, or add a sprinkle of pepper jack for more meltiness and bite. If you’re dairy-free, try a plant-based cream cheese and a shredded dairy-free cheese blend.

Frequently Asked Questions

Can I use rotisserie chicken instead of cooking chicken?

Yes. Shred about 2 cups of rotisserie chicken. You may reduce the cooking time slightly since the chicken is already cooked, but you still want to heat everything through and let the flavors meld.

Is this recipe freezer-friendly?

Absolutely. Assemble the casserole (without baking) and freeze for up to 2 months. Thaw overnight in the fridge and bake at 375°F (190°C) for 25-30 minutes, or until hot and bubbling.

How can I make this dairy-free?

Use a dairy-free cream cheese alternative and your favorite dairy-free shredded cheese. Ensure the buffalo sauce is dairy-free as well. The texture may be slightly lighter, but the flavor stays bold.

What should I serve with this casserole?

Something bright and crunchy pairs nicely. A simple cucumber-dill salad, celery sticks with ranch, or a side of steamed broccoli keeps the meal balanced and adds color.
