Introduction

This Low Carb Chicken & Onion Flatbread is a delicious, guilt-free way to enjoy cheesy, savory flavors without the carbs. Crisp flatbread topped with tender chicken, caramelized onions, and a zesty lime crema makes for a perfect quick meal or snack.

Two long flatbread slices lie side by side on white parchment paper over a white marbled surface, each topped with layers starting from a thin, golden-brown crust. Above the crust is a smooth layer of bright yellow melted cheese covering the whole length. On top of the cheese, there are scattered pieces of cooked chicken that are off-white with some brown edges. Around the chicken are thin, caramelized caramel-brown onion slices, adding texture and color contrast. Finally, a pale creamy white sauce is drizzled in a zigzag pattern over each slice, sprinkled with small, fresh chopped green herbs for a fresh touch. photo taken with an iphone --ar 4:5 --v 7

Ingredients

8 ounces shredded mozzarella
2 ounces cream cheese

2/3 cup almond flour
1/3 cup coconut flour

1 teaspoon baking powder
1 large egg

1 tablespoon olive oil
2 onions (peeled and thinly sliced)
1 cup cooked chicken (chopped)

6 slices pepper jack cheese
6 slices mild cheddar cheese
2 tablespoons fresh cilantro (chopped)

1/4 cup sour cream
1 teaspoon fresh lime juice
Pinch of salt

Instructions

Step 1: Preheat your oven to 400°F (200°C).
Step 2: In a microwave-safe bowl, combine the shredded mozzarella and cream cheese. Microwave for 1 minute, stir well, then continue microwaving in 30-second intervals, stirring each time, until fully melted and smooth like fondue.
Step 3: Add the almond flour, coconut flour, baking powder, and egg to the melted cheese mixture. Mix by hand on wax paper or use a food processor with a dough blade until a soft, uniform dough forms.

Step 4: Divide the dough into two equal portions. With slightly wet hands, press each portion into a rectangular shape on a parchment-lined baking sheet. Bake for 10 minutes.
Step 5: While baking, heat olive oil in a large frying pan over medium-high heat. Sauté the thinly sliced onions until soft and caramelized to a golden brown.
Step 6: Remove the flatbread bases from the oven. Layer 3 slices of pepper jack cheese and 3 slices of mild cheddar on each. Evenly spread chopped cooked chicken and caramelized onions on top.

Step 7: Return the flatbreads to the oven for 8-10 minutes, until the cheese is bubbly and melted and toppings are heated through.
Step 8: Meanwhile, whisk together sour cream, fresh lime juice, and a pinch of salt to make the lime crema. Transfer to a zip-top bag and snip a corner for easy drizzling.
Step 9: Once baked, remove flatbreads from the oven. Drizzle generously with lime crema, sprinkle with fresh cilantro, slice, and serve immediately. For an extra kick, add crushed red pepper flakes if desired.

Tips & Variations

Use pre-cooked rotisserie chicken to save time on preparation.
For a spicy twist, add jalapeño slices along with the onions and chicken.
Swap coconut flour for more almond flour if you prefer a denser flatbread.

The lime crema can be replaced with a dollop of guacamole or salsa for variety.

Storage

Store leftover flatbread in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for 5-7 minutes to keep the crust crisp. Avoid microwaving to prevent sogginess.

How to Serve

A flatbread is cut into two long pieces on white parchment paper over a white marbled surface. The base layer is a light brown crispy flatbread crust. On top, there is a thick layer of melted bright yellow cheese covering the flatbread evenly. The next layer consists of pieces of cooked chicken with a golden-brown outside, scattered evenly on the cheese. Slices of caramelized onions with a shiny dark brown color are spread across the chicken. Dollops of white creamy sauce are drizzled in a zigzag pattern over the top. The dish is finished with a sprinkling of chopped fresh green parsley leaves giving a fresh look. Photo taken with an iphone --ar 4:5 --v 7
