Quick answer
Heat the oven to about 350 to 375°F (175 to 190°C), put the pasty on a baking sheet, and bake roughly 15 to 25 minutes if it is thawed or refrigerated, or roughly 35 to 45 minutes if frozen. Large pasties can take longer. These are typical vendor guidelines, so check the package for your product.
What you need
- A baking sheet, lined with parchment if you like
- Oven mitts
- An instant-read thermometer (helpful for the filling)
- Foil, if the crust browns too fast
Step-by-step from thawed or refrigerated
- Heat the oven to 350 to 375°F (175 to 190°C).
- Unwrap the pasty completely, removing plastic, bags, and labels.
- Place it on the baking sheet, on the middle rack. There is no need to grease the pan.
- Bake for about 15 to 25 minutes, until the crust is golden and the filling is steaming hot.
- Let it stand for a few minutes. The filling stays very hot longer than the crust suggests.
Reheating from frozen
Bake a frozen pasty at the same temperature, but allow roughly 35 to 45 minutes, and longer for a very large one. If the crust is darkening before the center is hot, tent loosely with foil. Cooking from frozen is often the simplest option because it avoids the thawing step. The same approach applies to other frozen oven foods, such as frozen cabbage rolls or a frozen fruit pie.
Keep the crust crisp
- Use the oven rather than the microwave when you can.
- Place the pasty directly on a baking sheet instead of wrapping it.
- A wire rack set on the sheet lets air reach the bottom crust.
- Skip foil at the start, and use it only if the top browns too much.
Doneness check
Pasties usually contain meat, so they must be hot all the way through. USDA guidance for reheating leftovers is to reach 165°F (74°C). Insert a thermometer into the center through a steam vent or the side. If it’s not hot enough, return it to the oven for several more minutes. Pasties that contain cured meats, such as ham or bacon, follow the same rule. For more on handling cured pork, see our guide to cooking a ham in the oven.
Microwave and other methods
The microwave heats quickly but tends to leave the crust soft and the filling unevenly hot. If you use it, heat in short bursts at reduced power, rest, and check the temperature. Times vary widely by wattage and pasty size, so no single time is reliable. Microwaved pastry is safe to eat, but won’t be crisp. A toaster oven or air fryer can work at a similar temperature, using a shorter time and a close watch. You can also finish a microwaved pasty for a few minutes in a hot oven to crisp the crust.
Should you thaw first?
You don’t have to. Many makers say frozen pasties can go straight into the oven with extra time. If you do thaw, do it in the refrigerator, not on the counter, and cook promptly after.
Storing leftovers
Refrigerate cooked pasties within two hours and eat within a few days. Wrap them well to protect the crust, or freeze them for longer storage. Reheat only once if possible, since repeated reheating dries the pastry and filling.
FAQ
How long to reheat pasties in the microwave? It depends on the microwave and pasty. Use short intervals and check that the center is hot.
How do you reheat pastry in the oven? At around 350 to 375°F on a baking sheet until hot and crisp, often 10 to 20 minutes for small items.
Can you cook pastry in the microwave? Yes, but the crust softens.
Do you thaw frozen pasties before cooking? Not required; allow more oven time if cooking from frozen.
