Reheating croissants in the air fryer is simple. Follow these steps for bakery-fresh results:

1. Preparation

Start by properly preparing the croissants:

– Remove croissants from original packaging and unwrap individually. This prevents moisture from building up during reheating.

– If frozen, allow croissants to thaw completely before reheating. This ensures even cooking.

– Cut any large croissants in half. Smaller pieces will reheat faster.

2. Set Up the Air Fryer

– Preheat air fryer to 325°F. This temperature evenly reheats croissants.

– Line the air fryer basket with parchment paper or aluminum foil. The nonstick surface prevents sticking.

– Place croissants in a single layer in the basket, leaving space between them. This allows air circulation for even reheating.

3. Cook Time and Temperature

– Cook at 325°F for 5-7 minutes. This gives croissants time to heat through without over-browning.

– For frozen croissants, add 2-3 minutes. Frozen pastries take a bit longer.

– Check frequently and remove croissants once warmed through and slightly crispy on the outside.

4. Results

– Croissants reheated in the air fryer will be lightly browned and crispy on the outside.

– The interior will taste freshly baked and fluffy.

– Enjoy your croissants right away for the perfect texture.

Following these simple air fryer instructions results in bakery-fresh Costco croissants ready to enjoy again.
