- 1 tsp smoked paprika
Onion Gravy
- 2 large yellow onions, sliced
- 6 garlic cloves, peeled
- 2 cups beef broth
- 2 tbsp Worcestershire sauce
- 1 tbsp soy sauce
- 1 tbsp tomato paste

Step-by-Step Instructions
1. Season the Brisket
Pat the brisket completely dry with paper towels.
Season all sides with salt, black pepper, garlic powder, onion powder, and smoked paprika.
Allow the seasoned brisket to rest for about 10–15 minutes while you heat the skillet.
2. Sear the Brisket
Heat olive oil in a large skillet over medium-high heat.
Add the brisket and sear for 3–4 minutes per side, until a deep brown crust develops.
Transfer the browned brisket to the slow cooker.
3. Prepare the Onions
Add the sliced onions to the same skillet.
Cook for 4–5 minutes, stirring occasionally, until they begin to soften and pick up the browned flavor from the pan.
Add the garlic cloves and cook for another 30 seconds.
Transfer the onions and garlic around the brisket in the slow cooker.
4. Make the Braising Liquid
In a bowl, whisk together beef broth, Worcestershire sauce, soy sauce, tomato paste, brown sugar, Dijon mustard, thyme, and black pepper.
Pour the mixture over and around the brisket.
Spoon some of the onions over the top.
5. Slow Cook
Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours, until the brisket is very tender and easily pierced with a fork.
For the most tender result, LOW heat is recommended.
Transfer the brisket to a cutting board and allow it to rest for about 15 minutes.
6. Slice and Serve
Slice the brisket against the grain into thick or thin slices, depending on your preference.
Return the slices to the slow cooker or arrange them on a serving platter.
Spoon the tender onions and rich cooking juices generously over the meat.
Finish with fresh parsley and black pepper before serving.
Cooking Tips
- Sear the brisket before slow cooking to develop a richer, deeper beef flavor.
- Cook the brisket fat-side up so the rendered fat helps keep the meat moist.
- Use LOW heat when possible for the most tender texture.
- Always slice brisket against the grain so each bite stays tender.
- Let the meat rest before slicing so the juices redistribute instead of running out.
Serving Suggestions
Serve this slow cooker beef brisket with:
- Creamy mashed potatoes
- Roasted carrots
- Buttered egg noodles
- Green beans
- Crusty dinner rolls
Storage
Store leftover brisket with some of the onion gravy in an airtight container in the refrigerator for up to 4 days.
Reheat gently in a covered skillet, slow cooker, or 325°F (165°C) oven with some of the cooking liquid to keep the meat moist.
Leftover Ideas
- Use sliced brisket in toasted sandwiches with melted cheese and onions.
- Chop leftovers and serve them over mashed potatoes or rice with gravy.
- Turn leftover brisket into tacos, quesadillas, or a hearty beef hash.
FAQs
Can I use a smaller brisket?
Yes. A 2–3 lb brisket works well, but begin checking for tenderness earlier since it may cook faster.
Do I need to sear the brisket first?
No, but searing adds a much richer crust and deeper flavor to the finished dish.
Can I add vegetables to the slow cooker?
Yes. Carrots, potatoes, mushrooms, or celery can be added around the brisket.
How do I know when brisket is done?
The brisket should be very tender and a fork should slide into the meat with little resistance. Slow-cooked brisket is typically best when cooked until tender rather than relying only on a minimum internal temperature.
