Ingredients
3 to 4 pounds beef brisket
The star of the dish, beef brisket is a flavorful cut that benefits tremendously from long, slow cooking. The extended cooking time allows the connective tissue to break down, giving you the tender, pull-apart texture that makes brisket so satisfying.
1 packet onion soup mix
Onion soup mix provides concentrated onion flavor along with seasoning, helping create a deeply savory sauce without requiring a long list of individual spices.
1 cup ketchup
Ketchup forms the flavorful base of the sauce. Its combination of tomato, sweetness, and acidity balances the richness of the beef while helping create that familiar old-fashioned glaze.
1/4 cup brown sugar
Brown sugar adds warm sweetness and caramelization to the sauce. It balances the tanginess of the ketchup and Worcestershire sauce and gives the finished brisket its irresistible sweet-savory character.
2 tablespoons Worcestershire sauce
Worcestershire sauce adds savory depth and a subtle tang. Just a small amount helps round out the sauce and gives the brisket a richer, more complex flavor.
How to Make Slow Cooker Beef Brisket
1. Prepare the brisket
Pat the beef brisket dry with paper towels. Place it fat-side up in the slow cooker.
If the brisket is too large for your slow cooker, cut it into two pieces so it fits comfortably and cooks evenly.
2. Make the sauce
In a medium bowl, combine the onion soup mix, ketchup, brown sugar, and Worcestershire sauce.
Stir until everything is thoroughly combined and the brown sugar is evenly distributed throughout the sauce.
3. Cover the brisket
Pour the prepared sauce over the brisket, spreading it over the top as evenly as possible.
Cover the slow cooker with its lid.
4. Cook low and slow
Cook on LOW for 8 to 10 hours, or until the brisket is extremely tender and can be pulled apart easily with a fork.
For the best texture, avoid repeatedly lifting the lid during cooking. Keeping the slow cooker covered helps maintain the steady heat and moisture the brisket needs.
5. Rest before slicing
Carefully transfer the cooked brisket to a cutting board.
Let it rest for 10 to 15 minutes before slicing. This gives the meat time to settle and makes it easier to cut without losing as much moisture.
6. Slice against the grain
Look carefully at the direction of the muscle fibers and slice the brisket against the grain.
Cutting against the grain shortens the muscle fibers and makes each bite noticeably more tender. If you’re going for a casual pot-roast presentation, you can also shred the brisket with two forks.
7. Finish with the sauce
If there is excess fat floating on the cooking juices, skim some off.
Spoon the rich sauce over the sliced brisket and serve immediately while hot.
Why This Recipe Is So Loved
The beauty of this recipe is its simplicity.
You don’t need to brown the meat, prepare a complicated marinade, or measure a dozen spices. The sauce comes together in minutes, and the slow cooker takes care of the long cooking process.
The combination of sweet brown sugar, tangy ketchup, savory onion seasoning, and Worcestershire sauce creates a sauce that tastes much more complicated than its five ingredients suggest.
It’s also wonderfully practical. You can start the brisket in the morning, let it cook throughout the day, and come home to a kitchen filled with the comforting aroma of slow-cooked beef.
And because brisket makes generous portions, it’s particularly useful when you’re feeding a family or entertaining guests.
Pro Tips for Perfect Slow Cooker Brisket
Choose the right brisket
A brisket with some visible fat and marbling will generally produce a more flavorful and succulent finished dish. Don’t worry about trimming every bit of fat away before cooking.
Keep the brisket fat-side up
Positioning the brisket fat-side up allows the fat to render during cooking and helps keep the meat moist and flavorful.
Don’t rush the cooking
Brisket is a cut that rewards patience. If it isn’t tender at the earlier end of the cooking range, give it more time. The goal is fork-tender beef, not simply beef that has reached a particular clock time.
Slice only after resting
Allowing the brisket to rest for 10 to 15 minutes makes slicing easier and helps retain its juices.
Always cut against the grain
This is one of the most important brisket tips. Even perfectly cooked brisket can seem chewy if it’s sliced with the grain.
Thicken the sauce if needed
If the cooking juices seem thinner than you’d like, transfer the sauce to a saucepan and simmer it for several minutes until it reduces slightly. Spoon the concentrated sauce over the brisket before serving.
Easy Variations
Sweeter Sunday Brisket
For a sweeter, more traditional glaze, increase the brown sugar from 1/4 cup to 1/3 cup. The extra sweetness pairs especially well with creamy mashed potatoes.
Onion Brisket
Place one thickly sliced onion underneath the brisket before adding the sauce. The onion becomes incredibly soft and flavorful as it cooks.
Make-Ahead Brisket
For especially neat slices and deeper flavor, refrigerate the cooked brisket overnight in its juices. The next day, remove any solidified excess fat, slice the beef, and gently reheat it in the sauce.
Shredded Brisket Sandwiches
Instead of slicing the meat, shred the tender brisket and pile it onto soft sandwich rolls. Spoon some of the sauce over the top for an easy leftover meal.
What to Serve With Brisket
A rich brisket deserves simple sides that can soak up the sauce.
Mashed potatoes are a classic choice, especially when topped with extra brisket juices. Buttered egg noodles and plain rice are also excellent for catching every bit of the savory sauce.
For vegetables, try:
– Roasted carrots
– Green beans
– Buttered cabbage
– Roasted vegetables
– Simple cucumber salad
For a larger Sunday dinner or potluck spread, add baked beans, creamy potato casserole, dinner rolls, or a crisp green salad.
How to Store Leftovers
Allow leftover brisket to cool and refrigerate it in an airtight container along with some of its sauce.
It will keep well in the refrigerator for several days. For the best texture, reheat the slices gently in their cooking juices rather than heating the beef until it becomes dry.
The leftovers are particularly good tucked into sandwich rolls, served over mashed potatoes, or reheated alongside roasted vegetables.
Frequently Asked Questions
Can I cook brisket on HIGH instead of LOW?
You can, but LOW and slow cooking is the preferred method for achieving the most tender brisket. The longer cooking time allows the connective tissue to break down gradually.
Should I sear the brisket first?
Searing can add another layer of browned flavor, but it isn’t necessary for this recipe. One of its biggest advantages is that it keeps preparation quick and simple.
Why is my brisket tough?
If brisket is tough, it may simply need more cooking time. Brisket becomes tender as its connective tissue gradually breaks down, so continue cooking until it is easily pierced and pulled apart with a fork.
Can I shred the brisket instead of slicing it?
Absolutely. Once it’s tender enough to pull apart easily, shred it with two forks and toss it with some of the cooking sauce.
