Party Appetizer

There’s just something about the holiday season that inspires me to get creative in the kitchen, trying out different quick and easy recipes. This crisp, golden puff pastry filled with spicy, savory mushrooms makes a perfect appetizer to kick off the Holiday gathering season.

Having a scrumptious appetizer spread is a “must have” for any holiday party event. Along with Baked Brie with Cranberry Sauce, Buffalo Cauliflower Wings and Easy Italian Bruschetta these are our crowd pleaser party favorites.

Quite recently, I was experimenting with easy snacks that take my taste buds for a ride, but at the same time, don’t take a whole lot of effort and kitchen time. And oh, of course, they need to be non-fried and non greasy too.

Air Fryer Appetizers

That’s when the Air Fryer Comes in handy. Making an array of such crispy and delightful snacks / appetizers is so easy and so rewarding when you use an Air Fryer. Using circulating warm air instead of deep frying in oil reduces the calorie count without sacrificing the taste and texture.

Speaking of Air Fryer Recipes, do check out these Sweet Potato Wedges, Crispy Zucchini Fries, Roasted Brussels Sprouts and Crispy Fingerling Potatoes. They all are wonderful food ideas that whole family will enjoy. 

These mushroom puffs are full of classic caramelized flavors of onion, garlic and mushrooms, in a flaky and crispy puff pastry that was air-fried to perfection. They are crispy, savory, easy and elegant! To say they were a total hit would be an understatement.

Ingredients:

You’ll need just a handful of ingredients to put these delightful puffs together. Exact measurements are listed in the recipe card below.

Puff Pastry : Puff Pastry is perfect for quick and easy appetizer. Use store brought puff pastry sheet. Make sure to thaw them properly on the kitchen counter. Use 1-2 Tablespoon milk to press the puffs together if needed.

Onion – Garlic-Mushroom Mixture : Olive Oil, Minced Garlic, Chopped onion and chopped mushrooms. I used baby portabella mushrooms but you can use any variety of mushrooms including white button mushrooms.

Seasoning : I am using red pepper powder and black pepper powder. Since caramelized onions and mushrooms have deep earthy rich flavors, you don’t really need too much seasoning. But feel free to use Italian, Taco seasoning or Cajun seasoning if you want to further spice it up. Since puff pastry is slight salty, adjust additional salt according to your taste.

Optional Garnishes : Fresh or dried herbs like chopped parsley, thyme or basil adds great depth of flavors.

How to Make the Mushroom Puff Pastry Bites in Air Fryer :

How to prepare the puff pastry Dough : Thaw the frozen puff pastry sheet on kitchen counter. They should be easy to roll and spread. Dust the kitchen counter or work space with little flour so the puff pastry easy to handle and doesn’t stick to the surface.

How to Make Mushroom Filling : In a saucepan, warm the oil on medium heat. Add the chopped garlic and onion and let this cook for about 3 minutes till the onions get translucent and brown. Add the chopped mushrooms, red pepper powder, salt and black pepper. Let this cook for about 4-5 minutes until the mushrooms are completely cooked. Turn off the heat and let this mixture cool for about 10 minutes.

Put the other 2 cut pastry on top of the mixture. Cut the squares. Press down all the sides using a fork. You can slightly brush the edges of the sheet with milk so it sticks well together.

How to Air Fry The Puffs : Spray the air fryer basket with some oil. Place the mushroom puffs onto the air fryer basket. Spray some oil on top of the puffs. Air fry for 8-10 minutes at 330 degrees Fahrenheit rotating halfway through.

How to Store the Leftover Mushroom Puffs

Leftover mushroom puffs can stay good in your refrigerator for 5-7 days. Just make sure you store them in an airtight container to preserve their freshness.

You can also freeze the puffs if you want to store them for a longer duration. Prepare them completely, but don’t air fry them. Transfer them to a freezer-safe container and then just pop them in when you need them.
