Ingredient Notes

Using high-quality ingredients can really elevate this simple casserole. Here’s what you’ll need:

  • Chicken: 3 cups cooked, shredded chicken (A rotisserie chicken is the ultimate shortcut here).

  • Bacon: 8 slices, cooked until crispy and crumbled.

  • Cream Cheese: 8 oz (1 block), softened to room temperature. This is the key to a smooth, creamy sauce.

  • Mayonnaise: ½ cup. Use a good quality, full-fat mayo (like avocado oil mayo for extra healthy fats).

  • Hot Sauce: ½ cup. Frank’s RedHot Original is the classic choice for that authentic Buffalo wing flavor.

  • Cheddar Cheese: 1 ½ cups shredded sharp cheddar, divided.

  • Mozzarella Cheese: ½ cup shredded mozzarella.

  • Jalapeños: 4-5 fresh jalapeños, sliced into rounds (remove seeds for less heat, leave them in for more fire).

  • Garlic Powder: 1 teaspoon.

  • Onion Powder: 1 teaspoon.

  • Optional Garnish: Green onions or fresh chives, sliced.

  • For Serving: Celery sticks, cucumber slices, or low-carb tortillas/wraps.


Instructions

Follow these simple steps to create the creamiest, cheesiest Buffalo casserole of your life.

Step 1: Prep the Ingredients

Preheat your oven to 375°F (190°C) .
If you haven’t already, cook your bacon until crispy. You can do this in a skillet on the stove, or for ease, bake it in the oven on a parchment-lined sheet at 400°F for 15-18 minutes. Once cooked, place it on a paper towel to drain, then crumble or chop it.
Wash your jalapeños and slice them into ¼-inch thick rounds. If you are sensitive to spice, use a small spoon to scrape out the white membranes and seeds.

Step 2: Make the Creamy Buffalo Sauce

In a large mixing bowl, combine the softened cream cheesemayonnaise, and hot sauce. Use a hand mixer or a sturdy whisk to blend until the mixture is completely smooth and well-combined. There should be no lumps of cream cheese.
Add the garlic powder and onion powder to the bowl and mix again.

Step 3: Combine the Casserole Base

To the bowl with the sauce, add your shredded chicken, half of the crumbled bacon, and 1 cup of the shredded cheddar cheese (saving the remaining ½ cup for the top).
Mix everything together with a spatula until the chicken is evenly coated in the creamy sauce.

Step 4: Assemble the Casserole

Transfer the chicken mixture to a greased 9×13 inch (or similar size) baking dish. Spread it out into an even layer.
Sprinkle the remaining ½ cup of cheddar cheese and the ½ cup of mozzarella cheese evenly over the top.
Arrange the sliced jalapeños over the cheese. Finally, sprinkle the remaining bacon crumbles over the top.

Step 5: Bake to Perfection

Place the casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the casserole is hot and bubbly around the edges, and the cheese on top is melted and just starting to turn golden brown in spots.
For a slightly browned and crispy cheese top, you can switch the oven to broil for the final 1-2 minutes. Watch it very closely during this step so it doesn’t burn.

Step 6: Rest and Serve

Remove the casserole from the oven and let it rest for at least 5-10 minutes. This allows it to set up, making it easier to serve. If you cut into it immediately, it will be very loose.
Garnish with sliced green onions or chives for a pop of color and freshness. Serve with celery sticks for dipping and a necessary cool crunch!


Tips for the Best Keto Casserole

  1. Soften that Cream Cheese: This is crucial. If the cream cheese is cold, you will end up with little white lumps in your sauce. Leave it on the counter for 30-60 minutes before you start, or microwave it in a bowl for 15-20 seconds to soften it.

  2. Adjust the Heat: The spice level is totally customizable. For a mild version, use only ¼ cup of hot sauce and remove all seeds from the jalapeños. For a “Suicide” level, use ¾ cup of hot sauce, add a dash of cayenne pepper to the sauce, and keep all the seeds in your jalapeños.

  3. Don’t Skip the Rest: We know you’re hungry, but letting the casserole sit after baking allows the fats to cool slightly and reabsorb, preventing a greasy plate and ensuring perfect slices.


Storage & Meal Prep

This recipe is a meal prepper’s dream!

  • Fridge: Store leftovers in an airtight container in the refrigerator for up to 4-5 days.

  • Reheating: Reheat individual portions in the microwave for 60-90 seconds. For best results (to keep the chicken from drying out), reheat in a skillet over medium-low heat with a tiny splash of water or extra hot sauce, covered, until warmed through.

  • Freezer: You can freeze this casserole! Assemble it in a freezer-safe dish (preferably aluminum or glass) but do not bake it. Cover tightly with plastic wrap and foil. Freeze for up to 3 months. To cook, thaw overnight in the refrigerator and then bake as directed, adding 5-10 minutes to the bake time since you’re starting from cold.
