How Long Does It Take to Cook a Pork Roast


Pork is one of those meats that you don’t want to overcook. The last thing you want is a dry, tough roast that in no way resembles the tender cut of meat it was intended to be. However, if you’re not careful with your timing, overcooking pork can happen quickly. In this article we’ll discuss how long it takes to cook a pork roast and why it’s so important not to mess up this step!

Preheat oven to 325 degrees F.

Preheat your oven to 325 degrees F. If you don’t know how to set the temperature, consult the manual for your oven or use a thermometer to check it. Most ovens have a gauge on their front panel, but if yours doesn’t, place a meat thermometer in the center of your roast and set it for 15 minutes. After that time has elapsed, remove the roast from its wrapper and place it in an uncovered pan with at least 1 inch of space around all sides of it (this helps keep moisture inside). Then put everything back into the oven!

Remove roast from packaging and discard plastic.

Remove the roast from its packaging and discard the plastic. The pork should be in a netting that can be removed easily by pulling on it.

  • Trimming the fat will help the roast cook faster and more evenly, which means you can get to eating sooner!
  • Removing excess fat also reduces calories and improves flavor by reducing the amount of drippings that come in contact with your meat.

Season both sides of the pork roast with desired seasonings, including salt and pepper.

Seasoning the pork roast is an important step, as it helps to create a flavorful crust. You can use any number of seasonings, including kosher salt or sea salt, fresh ground pepper, spice rubs and dry rubs. You can also season with wet ingredients like sauces or glazes (like barbecue sauce).

Place roast in a large roasting pan or on a large rimmed baking sheet.

Place the pork roast in a large roasting pan or on a large rimmed baking sheet. If you don’t have either of these things, you can still use the oven but your pork will probably be more likely to stick to the pan.

If you want to make sure that your roast cooks evenly and doesn’t get dried out or burned on one side, place it on top of a rack inside an uncovered roasting pan with about 1/2 inch (1 cm) water in the bottom of it. If using this method, keep an eye on things during cooking–you may need to turn down your oven temperature after adding extra liquid!

You can find a roasting rack at most grocery stores, usually near the pots and pans section. Roasting racks are also known as roasting pans or gridirons, depending on their design. They have many uses beyond cooking meat; they’re great for baking cakes, making jello molds and serving food at parties!

It takes a long time to cook a pork roast but it is worth it!

Don’t worry, it’s worth it.

  • Don’t cut the cooking time short. The longer you cook a pork roast, the more tender and flavorful it will be!
  • Don’t worry about burning the roast. You can always add extra liquid if your pan dries out before your pork is done cooking (and then turn down the heat to maintain an even simmer).
  • Don’t worry about overcooking or undercooking your roast–it’ll be fine either way!


The cooking time for a pork roast depends on the size of the roast and your oven. In general, it will take at least an hour for the pork to reach an internal temperature of 145 degrees F. If you’re cooking in a slow cooker, plan on about six hours for this same result.
