This slow cooker 5-ingredient honey mustard beef brisket is the kind of set-it-and-forget-it main dish I build my whole Easter menu around. It reminds me of the church basement potlucks I grew up with here in the rural Midwest—simple ingredients, long slow cooking, and a roast that slices up tender enough for Sunday company. The method couldn’t be plainer: you lay the brisket right in the slow cooker, spread honey mustard all over that raw beef with your hands, tuck in just three more pantry staples, and let time do the rest. By the time the afternoon light slants across the kitchen, you’ve got a savory-sweet brisket that tastes like you fussed all day, even though the slow cooker did the work.
I like to slice this brisket and spoon some of the warm honey mustard juices over the top, then serve it with buttery mashed potatoes or simple boiled baby reds so they can soak up every bit of the sauce. Buttered green beans or roasted carrots make a nice, bright plate alongside the rich meat. For Easter, I’ll usually add a soft dinner roll or a slice of homemade bread to mop up the juices, plus a crisp lettuce salad with a light vinaigrette to balance the sweetness. Leftovers are wonderful piled onto soft rolls for sandwiches the next day, with a spoonful of the extra sauce in place of mayo.
Slow Cooker Honey Mustard Beef BrisketServings: 8
Ingredients
3 to 4 pounds beef brisket, trimmed but with a thin fat cap left on
3/4 cup prepared honey mustard
1 large yellow onion, sliced
1 cup beef broth (or water with 1 teaspoon beef bouillon)
1 teaspoon kosher salt (or 3/4 teaspoon table salt), plus more to taste
Directions
Place the slow cooker insert on a steady surface, such as a sturdy dark countertop. Lay the beef brisket inside, fat side up, and pat it dry with paper towels so the honey mustard will cling nicely.
Scatter the sliced onion around and under the brisket as best you can. It doesn’t need to be perfect—just tuck some under the edges and leave the rest alongside the meat in the bottom of the slow cooker.
In a small bowl or measuring cup, stir the honey mustard to loosen it. Pour it over the top of the raw brisket, then use your clean hands or the back of a spoon to spread the honey mustard in an even layer over the entire surface of the meat. Try to coat all the nooks and crannies; this is where the flavor really settles in.
Sprinkle the salt evenly over the honey-mustard-coated brisket. Gently press it in with your fingers so it sticks to the surface rather than sliding off into the bottom of the slow cooker.
Carefully pour the beef broth around the sides of the brisket into the slow cooker, trying not to wash the honey mustard off the top. The liquid should come partway up the sides of the meat but not cover it.
Cover the slow cooker with its lid. Cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the brisket is very tender when pierced with a fork and can be sliced or gently pulled apart.
When the brisket is done, transfer it to a cutting board and let it rest for about 10 minutes so the juices settle. Meanwhile, taste the cooking liquid and adjust the salt if needed.
Slice the brisket across the grain into thin or thick slices, depending on your family’s preference. Return the slices to the slow cooker or arrange them on a platter and ladle some of the warm honey mustard onion juices over the top. Serve the remaining juices in a small pitcher or bowl at the table.
Variations & Tips
For a touch more savory depth without adding extra ingredients, you can season the brisket with freshly ground black pepper when you add the salt. If your honey mustard is very sweet and you prefer a sharper flavor, stir in a spoonful of plain yellow or Dijon mustard before spreading it over the meat. For a little smokiness that reminds me of summer cookouts, use a smoky-style honey mustard. If your brisket has a very thick fat cap, trim it down to about 1/4 inch so the sauce doesn’t become too greasy; you can always skim some fat from the top of the juices before serving. This same method works well with a smaller 2-pound brisket—just check for doneness a bit earlier, as it may cook faster. Leftovers keep nicely in the fridge for up to 3 days and reheat best gently in a covered dish with a splash of the cooking liquid to keep everything moist.
