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). Ingredients 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 Directions 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. Pat roast dry; sprinkle all sides with salt and pepper. Hannah Zimmerman Add roast; cook, turning often, until browned, 10 minutes. Hannah Zimmerman Remove from cooker. Add onions and garlic to cooker. Cook, stirring often to scrape browned bits, until just softened, 2 minutes. Hannah Zimmerman Press "cancel." Add browned roast, peppers, broth, butter, and ranch dressing mix. Hannah Zimmerman 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.) Let the pressure release naturally. (This will take 10 to 12 minutes.) Remove lid. Hannah Zimmerman Transfer roast to a deep serving platter. Stir pepper liquid into juices in cooker. Top roast with onion mixture; pour juices in cooker over mixture. Sprinkle with herbs. Serve the meat over mashed potatoes, egg noodles, or rice. Hannah Zimmerman 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. Rate it Print
