Preheat your oven to 400°F and line a large baking sheet with parchment paper. The parchment paper helps prevent sticking, keeps cleanup easy, and allows the flatbreads to crisp more evenly on the bottom while baking.

Place the keto flatbreads directly onto the prepared baking sheet in a single layer. Bake them plain for about 4–5 minutes until they become slightly firm and lightly crisp around the edges. This pre-baking step is important because it helps the flatbread hold up better under the toppings and prevents soggy pizza centers later.

While the flatbreads are pre-baking, add the shredded rotisserie chicken into a small mixing bowl and pour in the buffalo sauce. Stir thoroughly until every piece of chicken is evenly coated in the spicy sauce. If you prefer extra heat, you can always add a little more buffalo sauce to taste.

Remove the partially baked flatbreads carefully from the oven and place them on a heat-safe surface. For the buffalo chicken flatbread, spread the softened cream cheese evenly across the surface using the back of a spoon or spatula. The cream cheese creates a rich creamy layer that balances the spicy buffalo flavor beautifully.

Sprinkle shredded Monterey Jack and cheddar cheese generously over the cream cheese layer so the entire flatbread gets evenly covered with melty cheese. Add the buffalo chicken mixture on top, followed by finely diced red onion and thinly sliced jalapeños for crunch, spice, and extra flavor.

For the pepperoni flatbread, spread the sugar-free pizza sauce evenly across the second flatbread, leaving a small border around the edges like traditional pizza crust. Be careful not to overload with sauce because too much can soften the flatbread instead of keeping it crispy.

Sprinkle shredded Monterey Jack cheese generously over the pizza sauce so every bite becomes gooey and cheesy once baked. Arrange the pepperoni slices evenly across the top and finish with a generous amount of Italian seasoning for classic pizzeria-style flavor and aroma.

Return both flatbread pizzas to the oven and bake for approximately 6–7 minutes, or until the cheese becomes fully melted, bubbly, and lightly golden around the edges. The flatbread should look crisp underneath while the toppings become hot and flavorful.

Carefully remove the pizzas from the oven and, if desired, drizzle extra buffalo sauce over the buffalo chicken flatbread for even more spicy flavor and restaurant-style presentation.

Allow the flatbread pizzas to cool for 1–2 minutes before slicing. This short resting time helps the cheese settle slightly and makes the pizzas easier to cut cleanly without the toppings sliding off.

Slice the pizzas into strips or triangles using a sharp knife or pizza cutter and serve warm with your favorite keto-friendly dipping sauces or side dishes such as ranch dressing, Caesar salad, roasted vegetables, or buffalo dip.
