To reheat croissants in an air fryer, set the temperature to 160°C (320°F) and cook for 3-4 minutes until warmed through. This gentle heat revives the flaky layers without burning the delicate pastry, giving you results that rival a fresh bakery batch. Whether you’re dealing with leftovers from yesterday’s breakfast or a supermarket pack that’s lost its crunch, your air fryer is the secret weapon for pastry perfection.
The air fryer’s circulating hot air works wonders on stale croissants, mimicking the effect of a professional convection oven. Unlike microwaves that can make pastries soggy or conventional ovens that dry them out, the air fryer delivers even heat distribution. This means every layer of butter-rich dough gets evenly crisped while the interior stays light and airy.

Another advantage is speed – while traditional methods might take 10-15 minutes, the air fryer achieves better results in under five. It’s particularly brilliant for single servings when you don’t want to fire up the main oven. Just pop your croissant in the basket, and by the time you’ve poured your coffee, you’ll have a warm, fragrant treat ready to enjoy.
If your croissants have been refrigerated, let them sit at room temperature for 10 minutes first. This prevents the exterior from over-browning before the centre warms through. For extra crispness, lightly spritz the surface with water using a spray bottle – the moisture creates steam that reactivates the layers during reheating.
Start by preheating your air fryer to 160°C for 2 minutes – this ensures even heating from the moment the croissant enters the basket. Place the pastry in a single layer, leaving space between items if reheating multiple croissants. Avoid overcrowding as this leads to uneven results and prevents proper air circulation around each piece.
For standard-sized croissants, 3 minutes at 160°C usually suffices, but check at the 2-minute mark if your air fryer runs hot. Mini croissants might need just 2 minutes, while jumbo bakery-style ones could require 4 minutes. If you’re reheating filled croissants (like almond or chocolate), add an extra minute to ensure the filling warms through completely.
For croissants that have gone slightly hard, wrap them loosely in foil for the first 2 minutes of cooking, then uncover for the final minute to crisp the exterior. This technique works wonders for day-old pastries. Discover more clever tricks in our air fryer recipes collection, including sweet and savoury ideas.
If your croissants are browning too quickly, reduce the temperature by 10°C and extend the cooking time slightly. Uneven browning often means your air fryer basket needs rotating – most models benefit from a quick shake or turn halfway through cooking. For models with strong top heating elements, placing a small piece of foil over the darkest areas can prevent burning.
Should your reheated croissants feel dry, try brushing them very lightly with melted butter before air frying. This adds moisture and enhances flavour. Alternatively, serve with jam or dipping sauces to compensate. Remember that proper air fryer maintenance ensures consistent performance for all your reheating needs.
Freshly reheated croissants pair beautifully with coffee or hot chocolate for breakfast. For a decadent twist, slice them horizontally and fill with ham and cheese before briefly air frying again to melt the filling. They also make excellent bases for bread pudding – tear stale croissants into chunks and use them in our air fryer dessert recipes.
To maximise freshness, store croissants in an airtight container at room temperature for up to 2 days. For longer storage, freeze them individually wrapped in foil, then reheat straight from frozen by adding 1-2 minutes to the cooking time. Avoid refrigeration unless absolutely necessary, as it accelerates staling in baked goods.
When buying croissants specifically for later reheating, choose ones with good structural integrity – overly soft or pre-sliced varieties may not hold up as well. Bakeries often sell day-old pastries at discount, which are perfect candidates for air fryer revival. Explore our breakfast recipe ideas for more morning inspiration using your air fryer.
