How Long to Cook Pork Loin Roast in Instant Pot?

The optimal cooking time for a pork loin roast in an Instant Pot is typically 20-25 minutes per pound on high pressure, followed by a natural pressure release of 10-15 minutes, ensuring a moist and tender result. Remember to check the internal temperature with a meat thermometer; it should reach at least 145°F (63°C).

The Magic of Pork Loin in the Instant Pot

Pork loin, often confused with the fattier and more flavorful pork shoulder (also known as pork butt), is a lean cut of meat prized for its versatility. However, its leanness can also be its downfall. Overcooking a pork loin results in a dry and tough piece of meat. The Instant Pot offers a solution, providing a moist cooking environment that helps retain the pork’s natural juices and tenderizes the meat much faster than traditional roasting methods.

Benefits of Using an Instant Pot for Pork Loin

Cooking pork loin in an Instant Pot boasts several advantages:

• Speed: Significantly reduces cooking time compared to oven roasting.
• Moisture Retention: The pressure cooker environment traps moisture, preventing the pork from drying out.
• Convenience: Set it and forget it! Once the Instant Pot is programmed, minimal monitoring is required.
• Flavor Infusion: The high-pressure environment helps marinades and seasonings penetrate the meat more effectively.
• One-Pot Cooking: You can often cook the pork loin with vegetables in the same pot, streamlining meal preparation.

The Step-by-Step Process

Successfully cooking pork loin in an Instant Pot involves a few key steps:

1. Preparation: Trim excess fat from the pork loin and pat it dry. This promotes better browning.
2. Searing (Optional but Recommended): Searing the pork loin on all sides in the Instant Pot before pressure cooking adds depth of flavor and improves the appearance. Use the sauté function for this step.
3. Seasoning: Generously season the pork loin with your favorite dry rub or marinade. Salt and pepper are essential, but consider adding garlic powder, onion powder, paprika, or herbs like rosemary and thyme.
4. Adding Liquid: Pour 1-2 cups of broth (chicken or vegetable work well) or water into the Instant Pot. This is essential for creating steam and pressure.
5. Placement: Place the pork loin on a trivet inside the Instant Pot. This prevents the meat from sitting directly in the liquid and becoming soggy.
6. Pressure Cooking: Secure the lid, ensure the pressure valve is set to “sealing,” and cook on high pressure for the recommended time (20-25 minutes per pound).
7. Natural Pressure Release (NPR): Allow the Instant Pot to naturally release pressure for 10-15 minutes after cooking. This allows the internal temperature of the pork to equalize and prevents it from drying out.
8. Quick Release (Optional): If you need to release the remaining pressure quickly, carefully turn the pressure valve to the “venting” position. Be cautious of the escaping steam. Note: A full quick release can sometimes result in a drier roast.
9. Resting: Remove the pork loin from the Instant Pot and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
10. Slicing: Slice the pork loin against the grain for maximum tenderness.

Marinade and Seasoning Suggestions

A flavorful marinade or dry rub can elevate your Instant Pot pork loin. Here are a few suggestions:

• Dry Rub: A simple combination of salt, pepper, garlic powder, onion powder, paprika, and dried herbs like rosemary and thyme.
• Honey Garlic Marinade: Combine honey, soy sauce, garlic, ginger, and a touch of red pepper flakes.
• Apple Cider Marinade: A blend of apple cider vinegar, apple juice, brown sugar, mustard, and savory herbs.

Common Mistakes to Avoid

• Overcooking: The most common mistake! Use a meat thermometer to ensure the pork reaches an internal temperature of 145°F (63°C).
• Insufficient Liquid: Not enough liquid can prevent the Instant Pot from reaching pressure and may result in a burn warning.
• Skipping the Searing Step: Searing adds significant flavor and improves the appearance of the pork.
• Cutting Too Soon: Allowing the pork to rest before slicing is crucial for moisture retention.
• Ignoring the Natural Pressure Release: A natural pressure release helps prevent the pork from drying out and ensures even cooking.

Frequently Asked Questions

1. Can I cook a frozen pork loin roast in the Instant Pot?

Yes, you can, but you’ll need to increase the cooking time by approximately 50%. Ensure the internal temperature reaches 145°F (63°C). It’s also recommended to sear the frozen pork loin if possible after briefly thawing the exterior.

2. What is the ideal internal temperature for pork loin?

The USDA recommends cooking pork to an internal temperature of 145°F (63°C), followed by a three-minute rest. Use a reliable meat thermometer to ensure accuracy.

3. What type of broth is best for cooking pork loin in the Instant Pot?

Chicken broth and vegetable broth are excellent choices. They add subtle flavor and moisture to the pork. You can also use water, but broth provides a richer taste. Avoid using broths with high sodium content, unless adjusting the amount of salt in your recipe accordingly.

4. Can I add vegetables to the Instant Pot with the pork loin?

Absolutely! Root vegetables like potatoes, carrots, and onions work well. Add them to the Instant Pot at the same time as the pork loin, or slightly later if you prefer them less cooked.

5. How do I prevent the pork loin from sticking to the bottom of the Instant Pot?

Using a trivet is essential to prevent sticking. Also, ensure there is sufficient liquid in the pot before pressure cooking.

6. What if my Instant Pot gives me a “burn” warning?

This usually indicates that there isn’t enough liquid in the pot or that something is stuck to the bottom. Stop the Instant Pot, release the pressure (carefully!), and add more liquid. Make sure nothing is stuck, then resume cooking. Monitor more closely.

7. Can I use a quick release instead of a natural pressure release?

While possible, a natural pressure release is recommended for a more tender and juicy result. Quick release can lead to a drier pork loin. If you must use quick release, monitor the internal temperature closely and adjust the cooking time accordingly.

8. How do I make gravy from the drippings in the Instant Pot?

After removing the pork loin, strain the drippings from the Instant Pot. Use the sauté function to thicken the drippings with a slurry of cornstarch and water or flour and water. Season to taste.

9. What if my pork loin is still tough after cooking?

If the pork is tough, it may be undercooked or overcooked. Ensure you are using a meat thermometer to verify the internal temperature. Overcooking can surprisingly make it tough, as it dries out the proteins. Adding more cook time often makes it worse.

10. How long does pork loin last in the refrigerator after cooking?

Cooked pork loin will last for 3-4 days in the refrigerator when properly stored in an airtight container.

11. Can I freeze cooked pork loin?

Yes, cooked pork loin can be frozen. Wrap it tightly in plastic wrap and then in a freezer bag. It will last for 2-3 months in the freezer. Thaw in the refrigerator before reheating.

12. What are some serving suggestions for Instant Pot pork loin?

Pork loin is incredibly versatile! Serve it sliced with roasted vegetables, mashed potatoes, or rice. You can also use it in sandwiches, salads, or tacos. It also works well in pulled pork sandwiches, as it’s so easily shredded when properly cooked.
