How to Make This Easy Crockpot Pot Roast
Step 1: Prep the Vegetables: Spray the inside of your crockpot with cooking spray. Slice the onion and layer it on the bottom. Add the peeled and sliced potatoes, minced garlic, and large-chopped carrots on top. The vegetables go on the bottom so they cook in the broth and soak up all that flavor.
Step 2: Season and Place the Roast: Remove the sirloin cap roast from its packaging. Season generously on all sides with salt and black pepper. Place the roast fat-side up on top of the vegetables. Fat-side up is important for this crockpot pot roast, the fat renders as it cooks and bastes the meat naturally.
Pro tip: If you have a few extra minutes, sear the roast in a hot skillet with a drizzle of oil for 2 to 3 minutes per side before adding it to the crockpot. It adds a beautiful brown crust and deeper flavor to the finished pot roast.
Step 3: Add the Broth: Warm 2 cups of water and stir in 2 teaspoons of Better Than Bouillon Beef until dissolved. Pour the broth into the crockpot around the sides of the roast, not over the top.
Step 4: Cook Low and Slow: Set the crockpot to LOW. For a 1.5 lb roast, cook 4 to 5 hours. For a 2.5 to 3 lb roast, plan for 6 to 8 hours. Your easy crockpot pot roast is done when it reaches an internal temperature of 160°F and pulls apart easily with a fork.
Pro tip: Do not lift the lid while it is cooking. Every time you peek, you release heat and add 20 to 30 minutes to the cooking time.
Step 5: Rest and Serve: Transfer the roast to a cutting board and let it rest for 10 minutes before slicing or pulling apart. Serve alongside the potatoes and carrots and spoon the rich cooking broth over everything as a natural gravy.
