Ingredients
Making savory pastry puffs in an air fryer requires just a few ingredients. I have made these turnovers with a filling of spinach, mushrooms, and cheese. However, you can easily adapt it to use vegetables or fillings of your choice.
I have used fresh baby spinach and fresh sliced baby Bella mushrooms. You can also use regular spinach and chop them. Other varieties of mushrooms can also be used.
I have used pepper jack cheese, but cheddar or mozzarella would work fine as well. For seasoning, only garlic powder, salt, serrano pepper, and little oil are needed.

The other main ingredient is the pastry dough. I have used the frozen puff pastry sheets available in the freezer section in the grocery stores. You will have to thaw it depending on the instructions. I just kept it outside at room temperature for 15 minutes before rolling it.
Instructions
It might seem daunting and challenging however, making these mushroom spinach turnovers in the air fryer is very easy. It involves just two steps: the first is to make the filling with mushrooms and spinach and the second step is to fill the stuffing in frozen puff pastry, and then air fry it.
I have used the air fryer to make the filling, however, you can also make it on the stovetop in a pan. Mix sliced mushrooms, oil, garlic powder, serrano pepper, and salt in a mixing bowl. Give it a quick toss to ensure the mushrooms are well coated with oil and spices.
Place the mushroom mix in the preheated air fryer for 7 minutes at 390°F. Add the spinach and cook for another 3 minutes. Open the basket and mix the spinach and mushrooms with the help of a kitchen tong.

Combine all ingredients except spinach into a large bowl and mix well.

Air fry the mushrooms and then add spinach.
I have used the frozen puff pastry and thawed them as per the directions on the package. All you need to ensure is that the pastry sheet is thawed enough to unfold it. If you keep it out of the freezer for too long, then it can become soft and will start sticking to the surface while rolling.
Carefully unfold the thawed puff pastry sheet on a lightly floured surface and gently roll it to make it even. Cut it into 6 pieces using a pizza cutter or a pastry cutter. Work one by one on each of the pieces and keep the rest in the refrigerator to ensure they are firm.

Roll and divide the pastry sheet into 6 parts.

Fill the stuffing and add grated cheese.
Roll the puff pastry piece with a rolling pin into a square shape. Fill one side with the mushroom spinach filling keeping about a centimeter distance from the edges. Wet the edges with the help of a basting brush as it helps in sealing it well.
Sprinkle some grated cheese and then fold the other half over it and then press the edges to seal them well. Use a fork if needed, for sealing the edges.
Since the filling is made in the air fryer, ensure that you clean the air fryer basket well before cooking the turnovers. Preheat the air fryer to 390°F and then place the turnovers in the air fryer basket. It takes about 7 minutes of time to air fry pastry puffs. Check after 7 minutes, they should be golden brown. Transfer them to a cooling rack.

Place the turnovers in the air fryer.

Air fry at 390°F for 7 minutes.
Serving suggestions
These mouthwatering savory puff pastries are best served warm for a snack or as an appetizer. You can serve them with some tomato ketchup or sriracha sauce if you want them spicier.
Variations
These mushroom spinach turnovers are savory and mildly spicy. You can easily adapt them to your taste and liking.
- Spicy - to make it spicier you can add more serrano pepper and some pepper while cooking the mushrooms.
- Filling - I have used mushrooms and spinach to make the filling. However, you can add onions or omit spinach. Also, you can add some other vegetables of your choice like zucchini or bell pepper.
- Cheesy - add cheese as per your liking. Cheddar, pepper jack, and mozzarella will go well.

Equipment
I have made the mushroom spinach stuffing as well as the turnovers in the Instant Vortex Plus air fryer and it will work fine in any air fryer.
The only thing is that after the mushroom spinach stuffing is done cooking, you will have to clean and pat dry the air fryer basket before you air fry the puffs.
You can alternatively make the stuffing on the stovetop in a pan and cook the puff pastries in the air fryer.
You will also need a pizza cutter to cut the puff pastry sheet after rolling it a little with a rolling pin. A basting brush is very helpful in wetting the pastry sheet slices from the edges.
Storage
It is best to serve the mushroom puffs once it is fresh out of the air fryer. However, you can always make them ahead of time and store them in the refrigerator in an airtight container. When you are ready to eat, simply reheat the pastry puffs in the air fryer at 350°F for 2-3 minutes.
If you want to plan ahead and make them in advance, you can stuff the puff pastry and line them in a tray and cover them with a food wrap. Refrigerate the uncooked turnovers for a day and then air fry them when you are ready.
Top tip
- While working on each puff pastry piece, keep the rest of them in the fridge. This helps them to stay firm and not loosen up while you work on the rest.
- Also, after making the pastry puffs, keep them in the fridge if your air fryer is busy. This will help the dough to stay firm and not stick to the surface.
