Start by preparing the au jus gravy mix according to the package instructions. Set aside to use as a dipping sauce for your wraps, ensuring it stays warm.
Place the tortillas on a plate and cover them with a damp paper towel. Warm in the microwave for 20 to 25 seconds. This step makes the tortillas more pliable and easier to fold into wraps.
Set your air fryer to 380 degrees F, and preheat for 3-5 minutes.
Lay a tortilla flat on a clean surface. Spread 1 tablespoon of horseradish sauce evenly over the surface to add a zesty flavor base.
Place one slice of provolone cheese on the tortilla to ensure a gooey, melted texture in every bite.
Add 2 tablespoons of crispy fried onions for a delightful crunch and a burst of flavor.
Top with 2 slices of roast beef, layering for optimal filling distribution.
Carefully fold the tortilla over the fillings, burrito-style, ensuring the contents are securely enclosed. Repeat the assembly process with the remaining tortillas.
Lightly brush each wrap with melted butter to achieve a golden, crispy exterior.
Place the wraps in the air fryer basket, ensuring they don't overlap.
Set cook time for 3-5 minutes, or until the tortillas are golden brown and the cheese inside has melted, creating a perfect blend of textures.
Once cooked, carefully remove the wraps from the air fryer. For an extra touch of richness, brush the wraps with additional melted butter.
Cut the wraps in half to make them easier to handle and dip.
Serve the wraps warm, accompanied by the prepared au jus gravy for dipping. Each bite combines the crispy tortilla with the savory fillings and the rich, flavorful au jus for a truly satisfying meal.
