Instant Pot Pork Tenderloin With Potatoes and Gravy

Instant Pot Pork Tenderloin with Potatoes and Gravy is the perfect weeknight one-pot meal made with creamy mashed potatoes and a rich gravy. For the most fork-tender pork tenderloin roast, use fresh or thawed tenderloins. Everyone will clean their plates with this delicious pork roast and potatoes recipe. Make this pork recipe a keto-friendly version by replacing the potatoes with a low-carb vegetable side.

This Instant Pot pork tenderloin recipe is a quick and easy pressure-cooked dinner. The pork is incredibly tender and savory. Since it’s a one-pot dish, the cut potatoes go in at the same time as the pork so they all cook together.

The gravy is made by using the concentrated juices at the bottom of the pot adding corn starch and water and simmering until a thick sauce forms. It’s amazing drizzled across the top of the meat, potatoes, and a vegetable side, like green beans.

Pressure cooker pork tenderloin is best made with fresh, and not frozen, pork. If it’s frozen, make sure to thaw it in the refrigerator (defrosting it overnight works best) before putting it in the pot.

After it’s cooked, place a sprig of rosemary as a garnish on top to give this comfort food an elevated appearance.

What is a Pork Tenderloin?

Pork tenderloin is a long, narrow, boneless cut of meat that comes from the muscle that runs along the backbone. It is an extra-lean cut of pork.

Pork Loin vs. Pork Tenderloin

You might think that Pork loin and pork tenderloin are the same cut of pork, but they’re the same, but they aren’t. Here’s what you need to know before you cook either meat and how to tell the difference between pork tenderloin and pork loin.

Pork tenderloin is one of the leanest, most tender cuts of meat, so it can be a little pricey at the grocery store. It’s always boneless and usually comes with two (one pound) tenderloins in a package.

Pork tenderloins do well with fast, high heat. Think quick roasting, broiling, grilling, sautéing, and braising. They’ll remain tender and juicy when cooked properly.

A pork loin is wider and flatter and can be a boneless or bone-in cut of meat. Pork loin comes from the back of the animal.

Pork loins need low and slow heat. Consider searing to brown it in a sauté pan, then finishing it in an oven and shredding it. Or grill it over medium, indirect heat. Cut a big pork loin into thick, meaty chops for a barbeque. They’re great for feeding a crowd.

Both of these cuts of pork tend to turn dry and tough if not cooked properly.

Recipe Variations

Pork tenderloin Instant Pot variations are easy to incorporate into this dish. Here are a few examples:

The best potatoes for this recipe are Yukon, but if you don’t have them, you can use red or russet instead. The key is to cut them to all the same size so they cook evenly.

As well as using garlic seasoning, you can make a garlic pork tenderloin by adding minced garlic to the pot.

If you’d rather use a lighter version of a sauce, drizzle a balsamic reduction on top instead of the gravy. You can make this reduction yourself or buy a bottle at your local grocery store.

How to Cook Pork Tenderloin in An Instant Pot

Searing the tenderloin

• Cut pork tenderloin in half to fit in your Instant Pot and cook evenly. Rub all-purpose seasoning over all sides of the pork.
• Brown the pork tenderloin on all sides. Remove the pork roast and let rest on a plate. Add the broth to the pot and stir to deglaze the pan.

Pressure cooking the roast and potatoes

• Add potatoes to the bottom of the pot and place the pork tenderloin on top. Cook on high pressure for 5 minutes.
• When pressure cooking is complete, do a natural release for 10 minutes (let the pot rest undisturbed), then perform a quick release (turn or twist pressure valve).
• Transfer the pork roast to a serving platter and cover loosely with foil.

Mashing the Potatoes

• Using a slotted spoon, remove the potatoes from a large mixing bowl. Add milk, butter, and seasoning.
• Mash the potatoes with a potato masher or mixer. Cover with foil.

Make the gravy

• Set the pressure coooker to sauté.
• Mix the cornstarch and cold water.
• Using a whisk, stir the mixture with the broth until smooth and continue stirring until the gravy is thick and bubbly.

Make this Instant Pot Pork Tenderloin Keto

For keto pork tenderloin, use keto-friendly vegetables like turnips, carrots, Brussels sprouts, eggplant, or green beans instead of potatoes. Replace corn starch with your preferred keto thickener.

Since the goal is to limit carbohydrates, other options would be asparagus, zucchini, spinach, and tomatoes. Since these vegetables aren’t as thick as potatoes, it might be best to cook them on the side so they don’t overcook in the Instant Pot with the pork.
