Ranch seasoning gives this old-school family favorite a delicious new spin, and an Instant Pot makes it come together even faster. Serve the tender meat over rice, egg noodles, or mashed potatoes for a hearty supper. If you don't own a multicooker, don't worry—this roast cooks up deliciously in a slow cooker (see instructions).


  • 2 Tbsp. canola oil

  • 3 lbs. boneless chuck roast, trimmed

  • 1 ½ tsp. kosher salt

  • 1 tsp. black pepper

  • 2 medium-size (10 oz. each) red onions, quartered

  • 3 medium garlic cloves

  • 1 cup jarred pepperoncini salad peppers, plus 2 Tbsp. liquid from jar, divided

  • ¼ cup beef broth

  • 2 Tbsp. unsalted butter

  • 1 (1-oz.) envelope ranch dressing mix

  • 1 Tbsp. chopped fresh dill

  • 1 Tbsp. chopped fresh chives


  1. Select "sauté" setting on a programmable pressure multicooker, such as Instant Pot. (Instructions, times, and settings may vary by brand or model.) Select "high" temperature setting; allow to pre-heat. Add oil to cooker.

  2. Cover cooker with lid, and lock in place. Turn steam release handle to "sealing" position. Select "manual/pressure cook" setting. Select "high" pressure for 55 minutes. (It will take 8 to 10 minutes to come up to pressure before cooking starts.)

  3. Let the pressure release naturally. (This will take 10 to 12 minutes.) Remove lid.

Chef's Notes

Slow-Cooker Method: Sear roast on the stove in a skillet over high heat. Place all ingredients in slow cooker. Cover; cook on low heat for 8 to 9 hours or on high for 5 to 6 hours.
