Ingredient Notes for Stuffed Pork Loin

Ingredients for Instant Pot Stuffed Pork Loin

Pork Loin: This recipe specifically calls for pork loin, which is different from pork tenderloin. While you can substitute with tenderloin, be prepared to adjust the cooking time and reduce the amount of filling. Tenderloins are generally thinner and can’t hold as much filling as pork loin.

Mushrooms: Brown bella mushrooms, also known as cremini mushrooms, offer a rich umami flavor that enhances the stuffing. You can substitute with white button mushrooms or even shirataki mushrooms. Make sure to chop the mushrooms finely for even distribution.

Shallots: Shallots provide a milder, more delicate aromatic flavor to the dish. If you don’t have shallots on hand, you can use finely chopped yellow onion as a substitute.

Step-by-Step Instructions: Instant Pot Stuffed Pork Loin

Sautéing the Filling

Get started by sautéing the flavorful filling that will elevate your pork loin.

Adding bacon to the Instant Pot
Sautéing mushrooms in the Instant Pot
Sautéing mushrooms, garlic, and herbs

  1. Turn your Instant Pot to the SAUTE setting or your Ninja Foodi to the SEAR/SAUTE setting. Press START to begin heating the pressure cooker.
  2. Add olive oil to the pot. Introduce the chopped bacon and sauté for 2 minutes.
  3. Add the chopped mushrooms to the pot and sauté with the bacon for another minute.
  4. Add the minced garlic, diced shallots, and rosemary. Sauté for one more minute until fragrant.

Deglazing the Instant Pot

  1. STOP the SAUTE function and transfer the flavorful filling mixture to a bowl or plate. Set aside to cool slightly.
  2. Pour a portion of the water into the bottom of the pot and use a wooden spoon to deglaze the pot. Scrape up any browned bits that may have stuck to the bottom. Pour the remaining water into the pot.

Butterflying and Stuffing the Pork Loin

Now, let’s prepare the pork loin to hold the delicious filling.

Slicing the pork loin
Continuing to slice the pork loin
Tenderizing the pork loin

  1. Using a sharp, large knife, slice the pork horizontally along the long side, cutting almost to the center of the meat. Then, carefully continue slicing to the other side, unrolling the pork as you cut (consider watching a video to understand the butterfly technique for pork loin).
  2. Lay the butterflied pork loin flat on the cutting board. If the meat is thicker than ½ inch, cover it with plastic wrap and pound it thinner using a mallet, rolling pin, or potato masher until it reaches about ½-inch thickness. Remove the plastic wrap.

Spreading mustard on the pork loin
Spreading mushroom mixture on the pork loin

  1. Spread the Dijon mustard evenly across the surface of the pork. Sprinkle kosher salt and ground black pepper evenly over the mustard-coated pork.
  2. Spoon the bacon and mushroom filling mixture evenly across the seasoned pork loin.

Rolling up the stuffed pork loin

  1. Working from one of the longest sides to the other, carefully roll the pork loin up to the end, creating a compact roll.

Tying the pork loin with kitchen twine

  1. Secure the seams with toothpicks or use kitchen string to tie and hold the rolled and stuffed pork loin together, preventing it from unraveling during cooking.
  2. Place a rack into the Instant Pot and spray it with cooking spray to prevent sticking. Carefully place the stuffed pork loin onto the rack.

Instant Pot settings for the pork loin
Cooked pork loin in the Instant Pot

  1. Assemble the pressure cooker lid, ensuring the pressure release valve is in the SEAL position. Select PRESSURE (or MANUAL on some Instant Pots) and set it to HI. Set the cooking time for 20 minutes and press START.
  2. Once the cooking cycle is complete, allow the pressure to release naturally for 10 minutes. After 10 minutes, quick-release the remaining pressure by carefully moving the pressure release valve to the VENT position. Remove the lid only when the unit has finished releasing all pressure and the pressure indicator has dropped completely.

Cooking is considered complete when the internal temperature of the pork loin reaches at least 145°F (63°C) when measured with a food thermometer. Let rest for 10-15 minutes before removing the toothpicks and/or kitchen string and slicing.

Making the Gravy

Transform the flavorful drippings into a luscious gravy.

Adding flour to the Instant Pot

  1. Remove the cooked pork loin and the rack from the Instant Pot. Turn the Instant Pot back to the SAUTE setting on HI. Add the ¼ cup of flour to the pan drippings inside the Instant Pot. Whisk continuously until the mixture is smooth and thick, forming a roux.

Optional: If the gravy is too thick for your liking, you can add some chicken stock to thin it out. Season with ground black pepper to taste, if desired.

Recipe FAQs: Instant Pot Stuffed Pork Loin

Gravy in a white pitcher

Can I use a pork tenderloin instead of pork loin?
Pork loin tends to be wider than tenderloin, making it a better choice for stuffing. However, you can use pork tenderloin if you prefer. You may need to adjust the amount of filling due to the smaller surface area and reduce the cooking time accordingly.
What’s the best way to store leftovers?
Allow the cooked pork loin to cool to room temperature before storing it in an airtight container in the refrigerator for up to 4 days. Reheat thoroughly before serving.

To make this recipe, you’ll need an electric pressure cooker. An 8-quart Ninja Deluxe XL Pressure Cooker/Air Fryer or an 8-quart Instant Pot Duo 9-in-1 Pressure Cooker are both excellent options. Please note: it is NOT recommended to attempt this recipe in a smaller 3-quart or 4-quart electric pressure cooker.
