    ⏲️ Time needed

    There's very little prep time before or after cooking, and the actual cooking time is 8-10 hours.

    🥘 Ingredients

    • beef roast
    • prepared mustard
    • onion soup mix
    • hoagie rolls
    • butter
    • non-stick cooking spray

    📋 Instructions

    Spray slow cooker with cooking spray, place roast in slow cooker, and spread mustard over the top of the roast. Pour the onion soup mix over top of the mustard, then cover and cook for 8-10 hours on low.

    Remove roast from the slow cooker and allow it to sit for 5 minutes. While the meat is resting, strain the broth to use for au jus.

    Butter each side of the hoagie rolls and toast until barely brown. Slice the roast and assemble sandwiches. Serve with au jus for dipping.

    💭 Tips

    Because the crockpot traps moisture inside the pot and cooks slowly, this recipe is suitable for less tender (and thus less expensive) cuts of meat. If you want to ensure lots of au jus, you can add one half to a full can of beef broth—put the broth in the crockpot first, then set the roast gently in the broth and add the mustard and soup mix as directed.

    Dried mustard can be substituted for the prepared mustard, but use it in a ratio of 1 teaspoon dry mustard to 1 tablespoon prepared mustard. Mix it with a couple of tablespoons of water before adding to the roast.
