Ingredients Method

Ingredients

  

• Pork tenderloins (1.5–2 pounds total; usually two small tenderloins)
• Ranch seasoning mix (1 packet, about 1 ounce)
• Au jus gravy mix (1 packet, about 1 ounce) or brown gravy mix
• Pepperoncini (8–12 whole peppers), plus a splash of brine
• Unsalted butter (2–4 tablespoons)
• Garlic (2–3 cloves, minced) or 1 teaspoon garlic powder
• Onion powder (1 teaspoon)
• Olive oil (1–2 tablespoons)
• Low-sodium chicken broth (1/2 cup)
• Black pepper
• Optional add-ins: sliced onion, baby potatoes, carrots, or mushrooms

Method

 

1. Trim and pat dry. Remove silver skin from the tenderloins. Pat the pork dry with paper towels so it sears well and the seasonings stick.
2. Season all over. Rub with olive oil, then sprinkle on ranch seasoning, au jus mix, garlic, onion powder, and black pepper. Press it in so it coats the surface.
3. Sear for flavor. Heat a large oven-safe skillet over medium-high. Add a little oil. Sear the pork on all sides until browned, about 2–3 minutes per side. Browning builds a richer crust and deeper flavor.
4. Build the sauce base. Pour in chicken broth and 2–3 tablespoons of pepperoncini brine. Scatter the whole pepperoncini around the pork. Dot the top with butter.
5. Choose your cooking method. For the oven: transfer the skillet to a 400°F (200°C) oven and roast 15–20 minutes, or until the thickest part reaches 145°F. For the slow cooker: skip searing if you want, then cook on Low 3–4 hours or High 1.5–2.5 hours until it hits 145°F. For the Instant Pot: add 1 cup broth, cook on High Pressure for 2 minutes per 1/2 inch of thickness (usually 6–8 minutes), then natural release 10 minutes.
6. Rest and slice. Move the pork to a board, tent loosely with foil, and rest 5–10 minutes. This keeps the juices in. Slice into 1/2-inch medallions.
7. Finish the sauce. While the pork rests, simmer the skillet juices for 2–3 minutes to slightly thicken. For a thicker gravy, whisk 1 teaspoon cornstarch with 1 tablespoon water and stir it in. Taste and adjust salt, pepper, or brine.
8. Serve. Spoon the buttery pepperoncini sauce over the sliced pork. It’s great with mashed potatoes, rice, or roasted veggies to catch the drippings.

Why This Recipe Works

Save

The magic comes from a few flavorful shortcuts. Ranch seasoning and au jus gravy mix build a savory base that clings to the tenderloin as it cooks.

Pepperoncini bring bright heat and acidity, cutting through richness and keeping the meat juicy. A little butter melts into the sauce for a silky finish and helps everything mingle. And because pork tenderloin cooks fast, you get a tender, sliceable roast in about 30–40 minutes—no all-day simmer needed.

• Freeze: Freeze in sauce for up to 2 months.

  Thaw overnight in the fridge and reheat gently.

Why This is Good for You

Pork tenderloin is a lean cut with high-quality protein and relatively low fat, making it a smart choice for balanced meals. Pepperoncini bring a small kick and a bit of vitamin C, while the broth-based sauce keeps things lighter than cream-heavy gravies. You control the sodium by choosing low-sodium broth and adjusting seasoning to taste.

Pair it with vegetables and a whole grain for a well-rounded plate.

What Not to Do

• Don’t overcook the pork. Tenderloin dries out fast past 145°F. Use a meat thermometer for accuracy.
• Don’t skip the rest. Cutting right away releases the juices onto the board, not into your dinner.
• Don’t drown it in liquid. A modest amount of broth and brine is enough for flavor and steam without washing off the seasoning.
• Don’t salt blindly. Ranch and au jus mixes are salty. Taste the sauce first, then add salt if needed.
• Don’t ignore the sear. Even a quick sear adds savory depth and better texture, especially for oven or slow cooker methods.

Alternatives

• No ranch packet? Mix 2 teaspoons dried parsley, 1 teaspoon each dried dill and onion powder, 1/2 teaspoon each garlic powder and dried chives, 1/4 teaspoon black pepper, and 1/4 teaspoon fine salt.
• No au jus? Use brown gravy mix, or 1 teaspoon beef bouillon plus 1/2 teaspoon onion powder and a pinch of paprika.
• Milder heat: Use fewer pepperoncini and more broth.

  You can also seed the peppers for less spice.

• More heat: Add crushed red pepper or a splash of hot giardiniera brine.
• Dairy-free: Swap butter for olive oil or a dairy-free butter alternative.
• Gluten-free: Choose certified gluten-free ranch and gravy mixes, or make the DIY blends above.
• Different cut: Use pork loin (larger and lean). Roast at 350°F until 145°F; timing will be longer. Or try boneless skinless chicken thighs and cook to 165°F.
• Veggie add-ins: Add sliced onions, mushrooms, or small potatoes to the pan or slow cooker.

  They’ll soak up the sauce.

FAQ

How spicy is Mississippi pork tenderloin?

It’s gently spicy. Pepperoncini are more tangy than hot. For very mild results, use fewer peppers and more broth.

For more kick, add extra peppers or a pinch of chili flakes.

Can I make it ahead?

Yes. Cook the pork, cool, and slice. Store in its sauce for up to 3–4 days.

Reheat gently on the stove with a splash of broth and finish with fresh pepperoncini for brightness.

Do I need to sear before slow cooking?

No, but it helps. Searing develops a crust and richer flavor. If you’re short on time, skip it and it will still taste great, just a touch less complex.

What’s the best way to tell when it’s done?

Use an instant-read thermometer.

Pull the pork at 145°F in the thickest part. It will be slightly pink in the center, which is safe and juicy for pork tenderloin.

Can I use the leftover sauce for something else?

Absolutely. Spoon it over mashed potatoes, rice, or roasted vegetables.

It also makes a great sandwich drizzle for leftover pork on a toasted roll.

How do I keep it from getting too salty?

Use low-sodium broth, taste before adding extra salt, and consider half a packet of au jus if you’re sensitive. The pepperoncini brine adds salt too, so go easy and adjust at the end.

What sides go best with this?

Mashed potatoes, buttery egg noodles, rice pilaf, roasted green beans, simple salads, or skillet corn all pair well. You want something to catch that tangy, buttery sauce.

Wrapping Up

Mississippi Pork Tenderloin brings big, zippy flavor with barely any effort.

With a quick sear, a few pantry packets, and those signature pepperoncini, you’ll have tender, sliceable pork and a sauce that begs for a side of potatoes or rice. Keep an eye on temperature, rest the meat, and taste the sauce before salting. Make it once, and it’ll slide right into your weeknight rotation—reliable, bold, and incredibly satisfying.
