  • Total Time: 21 minutes
  • Yield: 4 servings (32 bites)

Ingredients

Pretzel Bites

  • 5 Tbsp (35.5 g) coconut flour, divided

  • 1 tsp baking powder

  • ½ tsp garlic powder

  • ¼ tsp xanthan gum

  • 6 oz (170 g) shredded mozzarella cheese

  • 1 large egg

  • 1 Tbsp unsalted butter, melted

  • Coarse salt, for topping

Dipping Sauce

  • 2 Tbsp mayonnaise

  • 2 Tbsp spicy brown mustard

Instructions

  1. Mix Dry Ingredients – In a bowl, whisk 4 Tbsp coconut flour with baking powder, garlic powder, and xanthan gum. Reserve remaining 1 Tbsp flour.

  2. Melt Cheese – Microwave mozzarella in 30-second bursts (60–90 s total) until smooth and melted.

  3. Form Dough – Add dry mixture and egg to hot cheese; fold with a silicone spatula until combined.

  4. Knead & Shape – Dust work surface with reserved coconut flour. Knead dough 1 min until smooth. Divide into 4 ropes (8 in each) and cut each rope into 8 pieces (32 bites).

  5. Air Fry – Lightly oil air-fryer basket. Brush bites with melted butter, sprinkle with coarse salt, and air-fry at 350 °F (175 °C) for 5–6 minutes until puffed and golden.

  6. Make Sauce & Serve – Stir mayonnaise and spicy brown mustard together; serve with hot pretzel bites.

Notes

  • Make-Ahead: Shape bites, freeze on a tray, then store frozen up to 1 month. Air-fry from frozen, adding 1-2 minutes.

  • Flavor Twists: Swap garlic powder for everything-bagel seasoning, or sprinkle bites with cinnamon “sugar” (erythritol + cinnamon) for a sweet version.

  • Storage: Cooled bites keep 2 days, refrigerated in an airtight container. Re-crisp in air fryer 2 minutes.
