Instant Pot Pork Steak Recipe: Mississippi-Style Pepperoncini Tenderloin

This recipe transforms affordable pork into a tender, flavor-packed main course with minimal effort. The Instant Pot works its magic, turning tough cuts into melt-in-your-mouth perfection in under an hour.

Mississippi-style means tangy pepperoncini, rich butter, and a hint of spice create a sauce that’s irresistibly bold. The pork steaks soak up every bit of flavor, making each bite better than the last.

What emerges is fork-tender pork with a sauce so good you’ll want to drink it. The best part? The Instant Pot does most of the work while you focus on the sides.

Perfect for weeknight dinners or Sunday suppers, this dish delivers restaurant-quality results with homemade warmth. Here’s how to make it.

Ingredients for Instant Pot Pork Steak

Pantry staples and pork shoulder make this dish sing. Simple, bold, and so worth it.

The pork shoulder is key here—look for good marbling at Costco or your usual grocery store. It’s forgiving and turns melt-in-your-mouth tender under pressure. The pepperoncini peppers (from a jar near the pickles) add that signature tang. Meijer has great prices on the seasoning packets if you’re restocking. Don’t skip the butter—it’s what makes the sauce rich and glossy.

No ranch or au jus packets? Homemade mix works—1 tbsp each dried dill, parsley, garlic powder, onion powder plus 1 tsp salt covers ranch. For au jus, beef bouillon plus Worcestershire gets you close. The pork can be pork butt instead (it’s the same cut, just labeled differently). Short on time? Skip the flour for thickening—it’s still delicious, just less saucy.

Leftovers keep beautifully. Store sealed in the fridge for up to 4 days or freeze for 3 months. The sauce thickens as it cools, so thin with a splash of broth when reheating (worth the extra minute).

Step-by-Step Instructions for Instant Pot Pork Steak

This method guarantees fall-apart tender pork with minimal effort and maximum flavor.

Step 1: Sear the Pork Steaks for Deep Flavor

Cut the 2 lb Pork Shoulder into 1-inch steaks and pat them dry with paper towels. Season both sides generously with the 1 tsp Kosher Salt and 0.5 tsp Black Pepper. Heat the 2 tbsp Olive Oil in your Instant Pot using the sauté function on medium-high heat.

Working in batches, sear the pork steaks for 3-4 minutes per side until golden brown. Don’t overcrowd the pot—this ensures a proper sear instead of steaming. Transfer the seared steaks to a plate and set aside. The browned bits left in the pot will add incredible depth to your sauce.

Step 2: Build the Flavor Base with Aromatics

In the same pot, add the thinly sliced 1 whole Yellow Onion and cook for 2-3 minutes until softened and just starting to caramelize. Add the 4 cloves Garlic Cloves and cook for 30 seconds until fragrant—don’t let it burn.

Stir in the 1 package Ranch Seasoning Mix, 1 package Au Jus Seasoning Mix, and 1 tsp Dried Thyme. This trio of seasonings creates the signature Mississippi-style flavor profile. Pour in the 1 cup Beef Broth and use a wooden spoon to scrape up all the browned bits from the bottom of the pot.

Step 3: Pressure Cook to Tender Perfection

Return the seared pork steaks to the Instant Pot, nestling them into the liquid. Add the 1 cup Pepperoncini Peppers (including 1/4 cup juice) on top of the pork. The peppers will infuse their tangy flavor into the meat as it cooks.

Secure the lid and set the valve to sealing. Cook on high pressure for 15 minutes, then allow a natural release for 10 minutes before quick-releasing any remaining pressure. The pork should be fork-tender and practically melting at this point.

Step 4: Create a Rich, Velvety Sauce

Transfer the pork steaks to a serving platter and switch the Instant Pot back to sauté mode on medium heat. Whisk the 0.25 cup All-Purpose Flour into the cooking liquid to create a smooth slurry. This will thicken the sauce beautifully.

Add the 0.5 cup Unsalted Butter (cubed) and stir until fully melted and incorporated. The sauce should coat the back of a spoon and have a glossy, velvety texture. Taste and adjust seasoning if needed, though the seasoning mixes usually provide the perfect balance.

Pour the sauce over the pork steaks and serve immediately. The combination of tangy peppers, rich butter, and savory seasonings creates an irresistible sauce that soaks into every bite.

Creative Variations of instant pot pork steak

Spicy Pepperoncini Boost

For extra heat, add ½ cup sliced jalapeños with the 1 cup Pepperoncini Peppers. I also stir in 1 tsp red pepper flakes when building the flavor base. The additional spice balances beautifully with the rich butter sauce. 🌶️

Creamy Ranch Twist

After pressure cooking, stir in ½ cup heavy cream with the 0.5 cup Unsalted Butter for a luxurious, creamy variation. This creates a richer sauce that’s perfect for serving over mashed potatoes or egg noodles instead of the traditional pork steaks.

Asian-Inspired Fusion

Swap the seasoning packets for 3 tbsp soy sauce, 1 tbsp grated ginger, and 1 tbsp honey. Use 1 cup sliced bell peppers instead of pepperoncini. This version pairs wonderfully with steamed rice or noodles.

Mushroom Lovers

Add 8 oz sliced cremini mushrooms with the onions in Step 2. The mushrooms soak up the sauce and add a meaty texture. I love how they complement the pork’s richness without overpowering it.
