Choosing fillings: potato, sweet potato, meat, cheese, or vegetables
The fillings for knishes are incredibly versatile, and you can get creative with a variety of ingredients. Here are some options to choose from:
Potato
The classic potato filling is a popular choice, where a flavoured potato mixture is encased in a delicate, flaky pastry. The filling is typically made with seasoned mashed potatoes, fried onions, sour cream, and cheddar cheese. You can also add some butter, kosher salt, pepper, and schmaltz (rendered chicken fat) for extra flavour.
Sweet Potato
For a twist on the classic, sweet potatoes can be used as a filling. Combine baked or microwaved sweet potato with beef, onion, egg, salt, pepper, and a touch of gravy to make a savoury delight. This filling option adds a touch of sweetness and colour to your knishes.
Meat
Meat fillings are another option, typically made with ground beef or other minced meats. For a simple meat filling, fry onions in oil until golden, then add the meat and cook until it changes colour, stirring and crushing it with a fork. You can also add other ingredients like eggs, salt, and pepper to taste.
Cheese
Cream cheese or cheddar cheese can be used as a filling option, providing a rich and creamy texture to your knishes. Mix the cream cheese with other ingredients like herbs or spices to create a flavoured cheese filling.
Vegetables
If you're looking for a vegetarian option or simply want to incorporate more veggies into your knishes, try a root vegetable mash filling. Carrots, celeriac, parsnips, white potatoes, and sweet potatoes can be boiled and mashed with green onions, butter or oil, seasonings, and a splash of milk. This filling adds sweetness, colour, and extra nutrients to your pastry treats.

Preparing the dough: making your own or using store-bought
Preparing the dough is a crucial step in making knishes, and you have the option to make your own dough or take a shortcut and use store-bought dough.
If you're feeling ambitious and want to make your own dough from scratch, you'll need to gather the necessary ingredients, which typically include flour, water, and a leavening agent like yeast or baking powder. You can also add a fat source like butter or schmaltz (rendered chicken fat) for a richer, flakier dough. Once you have your ingredients, mix and knead them until you have a smooth, elastic dough. Then, let the dough rest and rise in a warm place until it doubles in size. This process can take anywhere from an hour to several hours, depending on the recipe and the type of yeast used.
On the other hand, if you're short on time or simply prefer a more convenient option, you can opt for store-bought dough or puff pastry. This is a great shortcut that doesn't compromise on taste. Look for puff pastry dough in the grocery store, typically found in the refrigerated section. You can also find pre-rolled sheets or blocks of dough that you'll need to roll out yourself. If you prefer a healthier option, opt for whole wheat flour dough instead of all-purpose flour.
Whether you decide to make your own dough or use a store-bought option, the key is to create a delicious, flaky, and golden crust for your knishes. The dough should be rolled out to an appropriate thickness, usually about 1/4 inch (0.6 cm) or as specified in your recipe. Cut the dough into desired shapes or sizes, depending on the type of knish you're making. You can make individual knishes by creating rolls or logs, then cutting them into pieces and sealing them with the potato mixture tucked inside.
Once the dough is prepared and shaped, it's time to fill and assemble the knishes. As you work, ensure that your filling is cool, as hot filling can make the dough soggy and difficult to handle. Place a generous amount of filling in the centre of each dough piece, being careful not to overfill. Then, bring the edges of the dough together and seal them tightly to prevent any filling from leaking during the cooking process. You can seal the knishes by crimping or pinching the edges, or using a fork to create a decorative pattern.
After assembling, your knishes are almost ready for the air fryer! If you have any dough scraps left over, you can use them to create decorative toppings or cut out shapes to place on top of the knishes before baking. If you're not ready to cook the knishes immediately, you can refrigerate them for a few hours or even freeze them for later. Simply place them on a baking sheet, flash-freeze them, and then transfer them to an airtight container or bag for longer storage.

Assembling the knish: sealing the filling inside the dough
The knish is a traditional Eastern European dish that consists of a doughy exterior with a flavourful filling. The dough acts as the perfect base to add whatever flavour you're craving, be it sweet or savoury. While traditional knishes are often baked or fried in oil, the air fryer offers a modern and healthier twist on this beloved snack.
Now, let's get into the details of assembling the knish and ensuring that the filling stays sealed inside the dough:
Preparing the Dough and Filling:
First, prepare the dough. You can make your own or, for a shortcut, use store-bought dough or puff pastry. If you're making your own, simply follow your favourite recipe or find a basic dough recipe online. While the dough is chilling, it's time to prepare the filling. The classic filling is mashed potatoes, but you can also use sweet potatoes or buckwheat groats cooked with onions and mushrooms. For a savoury twist, add caramelized onions, vegan ground meat, or even some schmaltz (rendered chicken fat cooked with onions) for extra flavour.
Assembling the Knish:
Once your dough and filling are ready, it's time to assemble the knish. Roll out the dough into logs or rolls, then cut them into pieces about 2 inches long. Take each piece and tuck the filling inside, being careful not to overfill. Pinch the dough firmly to seal the exposed edges, ensuring there are no gaps for the filling to leak out during cooking.
Cooking the Knish:
After assembling, it's time to cook your knishes in the air fryer. Preheat your air fryer to 375°F (190°C). Grease the air fryer basket with cooking spray or a small amount of oil to prevent sticking. Place the knishes, seam-side down, inside the basket, ensuring they don't touch. Depending on the size of your air fryer, you may need to cook in batches. Cook for 10-15 minutes, or until golden brown and crispy. Flip them halfway through to ensure even browning on both sides.
Storing and Reheating:
If you're not eating the knishes right away, they can be stored in the refrigerator for up to a day or frozen for longer storage. To freeze, place them in an airtight container or bag, ensuring they are well-wrapped to prevent freezer burn. When ready to enjoy, simply reheat in the air fryer or oven until warmed through.
And there you have it! A delicious, crispy knish with a soft and flavourful filling, all thanks to the magic of your air fryer. Enjoy this indulgent snack and feel free to experiment with different fillings and doughs to create your own unique knish creations.

Cooking in the air fryer: temperature, cooking time, and placement
Cooking knishes in an air fryer is a great way to achieve a delectable snack with a crispy twist. Here are the temperature, cooking time, and placement instructions for cooking perfect knishes in your air fryer.
Temperature
Set your air fryer to 375°F (190°C). This temperature ensures even and crispy cooking of the knishes.
Cooking Time
The cooking time for knishes in an air fryer can vary depending on the size and thickness of your knishes. On average, cook the knishes for approximately 10-15 minutes, or until they turn golden brown and have a crispy exterior. Keep a close eye on them to avoid overcooking.

Storing and reheating: refrigeration, freezing, and reheating methods
Storing and reheating knishes is a straightforward process and there are several options available.
Refrigeration
If you plan on eating your knishes within a few days, refrigeration is a good option. To store knishes in the refrigerator, wrap each one individually in parchment or wax paper, then place them in a large container or zip-top bag. Refrigerated knishes can be stored for up to 3-5 days.
Freezing
If you want to keep your knishes for longer, freezing is a great option. To freeze knishes, wrap them individually in plastic wrap, then double bag them to prevent freezer burn. Frozen knishes can be stored for up to 3 months.
Reheating in an Air Fryer
Reheating knishes in an air fryer is a convenient and effective way to enjoy this snack. Before reheating, ensure your knish is at room temperature, especially if it has been refrigerated or frozen, to allow it to heat evenly. Preheat your air fryer to 350°F (175°C) for about 3-5 minutes, then place the knish in the air fryer basket, ensuring it is not overcrowded. Reheat for approximately 3-5 minutes, or until the internal temperature reaches 165°F, and the exterior is golden brown.
Reheating in an Oven
Preheat your oven to 350°F. If your knish is refrigerated, heat it for 10-15 minutes, and if frozen, heat it for 30-40 minutes, or until it reaches your desired temperature. For a crispy crust, finish off the reheated knish in the oven for 1-2 minutes.
