These cheesy puff pastry jalapeño bites are the perfect appetizer for easy entertaining. They’re completey addictive and perfect for feeding a crowd.
So, it’s safe to say that anything wrapped in puff pastry is an automatic favorite, right? I mean, who could resist that crisp, buttery, golden flakiness? Most definitely not me. Now add cheese, jalapeños and sautéed onions and you have jalapeño bites so good, you’ll be struggling to only have one!
Can you use phyllo dough instead of puff pastry?
Yes you can, for this recipe, but the end result will be different. It’s not always suitable for phyllo pastry to substitute puff pastry but in most cases it will be fine. Brush at least 3 layers of phyllo with melted butter and layer together and then use as you would puff pastry. Take care to keep the puff pastry under a moist towel as it can dry out and become brittle quickly.
How to make cheesy jalapeño puffs
Using shop-bought frozen puff pastry makes this recipe very easy. Simply defrost the pastry overnight in the refrigerator. The filling is made by sautéeing an onion until soft and translucent then combining with grated mature cheddar and mozzarella and chopped pickled jalapeños. Use a mini muffin/pastry tray and lay small squares of pastry in each hollow then fill with the cheese mixture. Fold the corners over and pinch together then brush with egg and bake until golden, puffed and cooked through.

Oh these look absolutely delicious! I would eat the whole tray!
You and me both!
Can you prepare them up to the point of baking and freeze them to bake at a later date?
And if so, should you bake them right out of the freezer or should you thaw them before baking?
I haven’t tested this but it shouldn’t be a problem. I would bake them directly from frozen.
Only 25 minutes ? I’m in ! Thank you for sharing this beauty !
