Ingredients for Instant Pot Frozen Pulled Pork
Transform frozen pork into rich, smoky pulled pork with these pantry staples and spices.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Shoulder 🐖 | 3 lb | Bone-in or boneless, frozen |
| Brown Sugar 🧈 | ¼ cup | Light or dark variety |
| Paprika 🌶️ | 1 tbsp | Smoked or sweet variety |
| Garlic Powder 🧄 | 1 tbsp | Not garlic salt |
| Onion Powder 🧅 | 1 tbsp | Fresh ground preferred |
| Ground Cumin 🌿 | 1 tsp | Toasted for deeper flavor |
| Salt 🧂 | 1 tbsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Liquid Smoke 💨 | 1 tsp | Hickory or mesquite flavor |
| Apple Cider Vinegar 🍏 | ¼ cup | Balances sweetness and smoke |
| Chicken Broth 🍲 | 1 cup | Low-sodium preferred |
| Barbecue Sauce 🍯 | 1 ½ cups | Quality brand or homemade |
| Olive Oil 🫒 | 1 tbsp | For searing pork |
The pork shoulder is non-negotiable here. Bone-in adds depth, but boneless works if that’s what’s available. Most Costco or Sam’s Club locations carry frozen pork shoulder in bulk—perfect for this method. Look for pieces with good marbling (about 20-25% fat) to ensure the final product stays moist and tender. The liquid smoke is what delivers that classic barbecue flavor without the smoker.
No apple cider vinegar? White vinegar in a pinch (use slightly less). Swap chicken broth for beef broth or water—just adjust seasoning at the end. For the spice rub, freshly ground spices make a noticeable difference, but pre-ground works fine. The barbecue sauce can be store-bought (Stubb’s or Sweet Baby Ray’s are reliable), or use your favorite homemade version for a personal touch.
Cooked pork keeps beautifully in the fridge for up to 4 days or can be frozen for 3 months. Portion into meal-sized containers before freezing for easy reheating. The cooking liquid is gold—save it for beans or soups (it’s packed with smoky flavor).

Step-by-Step Instructions for Instant Pot Frozen Pulled Pork
This method transforms frozen pork shoulder into tender, smoky perfection with minimal effort.
Step 1: Create the Dry Rub and Sear the Frozen Pork
In a small bowl, combine the 1 tbsp Paprika, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tsp Ground Cumin, 1 tbsp Salt, and 1 tsp Black Pepper. This aromatic blend will form the flavor foundation.
Set your Instant Pot to the Sauté function and add the 1 tbsp Olive Oil. Once hot, sear the frozen 3 lb Pork Shoulder on all sides for 2-3 minutes per side until a golden crust forms. The pork will begin to thaw during this process, but don’t worry about it being completely defrosted.
Step 2: Deglaze and Pressure Cook
After searing, carefully pour in the 1 cup Chicken Broth to deglaze the pot, scraping up any browned bits from the bottom. These bits are packed with flavor and will enhance the final dish. Add the 0.25 cup Apple Cider Vinegar and 1 tsp Liquid Smoke to the pot, then sprinkle the dry rub evenly over the pork.
Secure the lid, set the valve to Sealing, and cook on High Pressure for 60 minutes. The pork will cook directly from frozen, absorbing all the smoky, spiced flavors as it tenderizes. The Instant Pot will take about 15-20 minutes to come to pressure before the cooking time begins.
Step 3: Natural Release and Shred
Once the cooking time is complete, allow the pressure to release naturally for 15 minutes, then quick-release any remaining pressure. This natural release helps the meat retain moisture, ensuring it stays juicy. Remove the pork shoulder from the pot and place it on a cutting board.
Using two forks, shred the pork into bite-sized pieces. It should pull apart effortlessly, with the fibers separating cleanly. Discard any large fat chunks or bones if your pork shoulder had them.
Step 4: Finish with Barbecue Sauce
Return the shredded pork to the Instant Pot and stir in the 1.5 cups Barbecue Sauce and 0.25 cup Brown Sugar. The residual cooking liquid will help thin the sauce slightly, creating a glossy, flavorful coating for the pork.
Set the Instant Pot to Sauté again and cook for an additional 5-7 minutes, stirring occasionally, until the sauce has thickened and the pork is fully coated. The sauce should cling to the pork, with a balance of sweet, smoky, and tangy flavors.
Pro Tips For Making Instant Pot Frozen Pulled Pork
- Add Liquid First: I learned this the hard way—always pour 1 cup of broth or water in the Instant Pot before adding frozen pork shoulder to prevent the burn notice and guarantee even cooking.
- Season the Rub: Mix the brown sugar, paprika, garlic powder, and onion powder together before rubbing it on the pork—sounds simple, but it actually changes the outcome by distributing flavors evenly.
- Skip the Thaw: Resist the urge to thaw the pork shoulder first; the Instant Pot handles frozen just fine, and you’ll save hours while still getting tender, fall-apart meat.
- Shred While Hot: After cooking, shred the pork immediately while it’s still hot—it absorbs the spices better, and you’ll avoid the dry, stringy texture that happens when it cools too much.

Frequently Asked Questions
Do I need to thaw the pork first?
No thawing required! The Instant Pot cooks frozen pork shoulder perfectly from rock-solid. Just add 10-15 minutes to the pressure cooking time to account for the frozen state.
Can I use a different cut of pork?
Pork shoulder works best due to its fat content, but pork butt is a great substitute. Avoid lean cuts like tenderloin—they’ll dry out. Stick with 3-4 lbs for even cooking.
What if my pork isn’t shredding easily?
It likely needs more time. Return it to the Instant Pot with extra broth and pressure cook for another 15-20 minutes. Undercooked pork resists shredding.
Can I skip the liquid smoke?
Yes, but the smoky flavor will be milder. Add 1 tsp smoked paprika to the rub or use a smoky barbecue sauce to compensate.
