Ingredients
  

Steak
  • 2 lb sirloin steak or chuck Cut into 1.5-inch pieces.
Seasonings and sauce
  • 1 oz ranch seasoning mix Use one packet.
  • 1 oz au jus gravy mix Use one packet.
  • 1 stick butter Slice for layering on top.
  • 0.5 cup pepperoncini peppers Use 8–10 peppers.
  • 0.25 cup pepperoncini brine Pour in to deepen flavor.
  • 0.5 cup beef broth Add to help create the pan sauce.
Serving and garnish
  • 1 mashed potatoes or egg noodles For serving.
  • 1 fresh parsley For garnish.

Equipment

  • 1 Dutch oven

Method
 

Cook the steak bites
  1. Add the steak pieces to the slow cooker. Spread them out so they sit evenly for more consistent tenderness.
  2. Sprinkle the ranch seasoning mix and au jus gravy mix over the steak. Aim for even coverage so the spices bloom into the sauce as it heats.
  3. Add the pepperoncini peppers, then pour in the pepperoncini brine and beef broth. Let the liquid pool around the steak for a classic buttery au-jus effect.
  4. Lay the sliced butter slices across the top of the steak. The butter will melt as the cooker warms and help thicken the sauce.
  5. Cook on low for 5–6 hours or high for 2.5–3 hours until the steak is tender. Use gentle pressure to check doneness—tender bite-sized pieces should break apart easily.
  6. Stir gently to coat the steak pieces in the buttery pan sauce. Keep the meat intact while mixing so every piece gets sauced.
Serve
  1. Serve the steak bites over mashed potatoes or egg noodles. Spoon extra pan sauce around the plate for that Mississippi-style finish.
  2. Garnish with fresh parsley before serving. Add it right at the end so the color stays bright.

Notes

Pro tip: don’t stir aggressively during cooking—handle gently once, right after the steak is tender, so the meat stays bite-sized. Refrigerate leftovers in an airtight container for up to 3 days; reheat in the microwave or on the stove with a splash of broth. Freezing is yes—freeze in portions for up to 2 months and thaw in the fridge overnight. Dietary swap: use reduced-sodium ranch seasoning mix and reduced-sodium au jus gravy mix to cut salt while keeping the same tangy pepperoncini flavor.
