How Long to Cook a Pork Rib Roast


Preparing a pork rib roast can be quite daunting, especially if you’re not sure how long to cook it. There’s nothing worse than cutting into your pork and realizing that it’s undercooked or overcooked. The key to a perfectly cooked pork rib roast is getting the cooking time just right. In this article, we will take a deep dive into the factors that affect the cooking time, steps for prepping and cooking, frequently asked questions, and tips for serving a delicious pork rib roast.

What is a Pork Rib Roast?

Before diving into how long to cook a pork rib roast, let’s talk about what exactly it is. A pork rib roast is a cut of meat from the loin section of the pig. It generally includes 8-10 ribs and can range in size from around 2-6 pounds. The two main types of cuts are bone-in and boneless. Bone-in is typically more flavorful but requires careful attention during cooking to ensure that the meat cooks evenly.

Different Types of Cuts Available:

  • Pork Loin Back Ribs: These come from high on the hog and have curved bones surrounding thin pieces of tender meat.
  • Pork Baby Back Ribs: Baby back ribs are shorter and curved more than spare ribs.
  • Spare Rib: They are longer than baby back ribs, with flat bones and more meat between them.

Factors Affecting Cooking Time

Several factors affect how long it takes to cook a pork rib roast. Let’s take a closer look at these below:

Weight and Size of the Pork Rib Roast:

As expected, the larger the pork rib roast, the longer it will take to cook. A rule of thumb is that it takes 20-30 minutes per pound to cook pork rib roast at 350°F. So if you have a 4-pound pork rib roast, it will take around 1.5 – 2 hours to cook.

Oven Temperature:

The temperature you set your oven to plays a significant role in cooking time. As mentioned before, a temperature of 350°F is a good starting point for cooking your pork rib roast.

Bone-in vs. Boneless:

Bone-in meat typically takes longer to cook than boneless meat due to the presence of bones which act as insulators. If you’re cooking a bone-in pork rib roast, you can expect it to take slightly longer than boneless.

Preparing the Pork Rib Roast Before Cooking:

Ensuring that your pork rib roast is at room temperature before cooking can significantly impact the cooking time. Remove the meat from refrigeration for around 20-30 minutes before cooking. Additionally, trimming off any large chunks of fat before cooking can help speed up the cooking process.

Preparing the Oven for Cooking

Before we dive into how to cook a perfect pork rib roast, let’s discuss some crucial steps to prepare your oven adequately.

Required Equipment:

You will need an oven-safe thermometer that can go up to at least 160°F, an oven-safe roasting pan or Dutch oven, aluminum foil, and something to lift the pork rib roast like tongs or spatulas.

Temperature and Preheating Instructions:

Preheat your conventional oven to 350°F before cooking your pork rib roast. You want your oven temperature consistent throughout the cooking process, so make sure it reaches and maintains 350°F before proceeding.

Cooking Pork Rib Roast: Step-by-Step Guide

Now that we’ve covered the basics let’s dive into how to cook a perfectly juicy pork rib roast.

Preparing the Pork for Cooking:

Pat the pork dry with a paper towel, and trim any large pieces of fat to ensure heat penetrates evenly. Season the pork with salt, pepper and any other spices you’d like. Rub your spice mix on all sides of the meat and allow it to sit for 20-30 minutes.

Searing the Pork Rib Roast:

Searing adds flavor and an extra crisp texture on top. Heat oil or butter in a skillet over medium-high heat. Add the pork rib roast, and brown on all sides.

Placing in the Oven to Roast:

Remove your browned pork rib roast from the skillet or Dutch oven using tongs or spatulas and place it in an oven-safe container. Remember to cover it tightly with aluminum foil, then place it in a preheated oven at 350°F.

Checking for Doneness:

Use an oven thermometer to check for doneness by inserting it into the thickest part of the meat without touching any bones. Once it reads 145°F, remove the pork rib roast from the oven and allow it to rest for around 15 minutes before slicing.

Tips for Cooking and Serving a Perfectly Cooked Pork Rib Roast

Here are some tips for taking your pork rib roasting game to another level:

Resting Time After Cooking:

Allowing your meat to rest after cooking is essential as it allows the juices to settle, resulting in tender meat. Give your cooked pork rib roast about 10-15 minutes to rest before slicing.

Serving Suggestions, Sauce Recommendations, and Sides:

The pork rib roast has a distinct flavor that pairs well with many sides and sauces. Consider serving with mashed potatoes, roasted vegetables, applesauce or gravy.

Troubleshooting Common Issues When Cooking a Pork Rib Roast

Here are some tips for dealing with common issues when cooking a pork rib roast:

Overcooking or Undercooking:

Undercooked pork is a genuine concern as undercooked meat is not safe to consume. Use an oven thermometer to monitor the internal temperature of the meat throughout the cooking process. Overcooked meat can be dry and tough, so make sure to remove the meat from the oven as soon as it reaches 145°F.

Using a Meat Thermometer to Check Doneness:

Using an oven-safe meat thermometer is crucial when preparing your pork rib roast. To ensure that your thermometer reads accurately, check it beforehand by placing it into boiling water.

Correcting Mistakes During Cooking:

If you find yourself in a situation where your pork rib roast is overcooked and dry, don’t throw it out just yet! You can salvage dry pork by slicing it thin and adding in a flavorful sauce or gravy.

1. How should I prepare my pork rib roast before cooking it?

Before cooking your pork rib roast, you should remove it from the fridge at least an hour before cooking and allow it to come to room temperature. Preheat your oven to 350°F (175°C), season the roast with your preferred seasonings, and then sear it in a hot skillet to give it a crispy crust.

2. How long do I need to cook my pork rib roast for?

The amount of time you need to cook your pork rib roast for will depend on its weight. As a general rule of thumb, you should plan to cook your pork rib roast for approximately 25 minutes per pound. Remember to check the internal temperature of the meat with a meat thermometer before serving. It should reach an internal temperature of at least 145°F (63°C).

3. Should I cover my pork rib roast while it cooks?

Yes, you should cover your pork rib roast with aluminum foil while it cooks. This will help to keep it moist and prevent the outside from drying out or burning. Remove the foil for the last 15-20 minutes of cooking time to allow the outside to develop a crispy crust.
