Step-by-Step Instructions
1. Prepare the Brisket
Preheat the oven to 325°F (165°C).
Pat the brisket thoroughly dry with paper towels.
Season all sides evenly with salt, black pepper, garlic powder, onion powder, and smoked paprika.
Allow the beef to rest for about 10 minutes while heating a large Dutch oven or heavy skillet.
2. Sear the Brisket
Heat olive oil over medium-high heat.
Add the brisket and sear for 4–5 minutes per side, until a deep brown crust develops.
Transfer the browned brisket to a plate and set aside.
3. Cook the Onions
Reduce the heat to medium and add butter.
Add the sliced onions and cook for 8–10 minutes, stirring occasionally, until softened and beginning to caramelize.
Add the garlic and tomato paste.
Cook for another minute until fragrant.
4. Prepare the Gravy
Pour in the beef broth and scrape up the flavorful browned bits from the bottom of the pan.
Stir in Worcestershire sauce, Dijon mustard, thyme, rosemary, black pepper, and bay leaf.
Bring the mixture to a gentle simmer.
5. Braise the Brisket
Return the brisket to the pan and spoon some of the onion gravy over the top.
Cover tightly with a lid or foil.
Transfer to the oven and braise for 3–4 hours, depending on the thickness of the brisket.
The beef is ready when it is very tender and a fork slides into it easily.
6. Finish the Gravy
Transfer the cooked brisket to a cutting board and let it rest for 15 minutes.
Remove the bay leaf.
Mix cornstarch and cold water until smooth, then whisk the mixture into the onion gravy.
Simmer for 3–5 minutes until the sauce becomes rich and glossy.
7. Slice and Serve
Slice the brisket against the grain into thick, tender slices.
Arrange on a serving platter and spoon the warm onion gravy generously over the meat.
Finish with fresh parsley and freshly cracked black pepper.
Serve immediately.
Cooking Tips
- Slice brisket against the grain for the most tender texture.
- Searing the beef before braising creates deeper flavor and a richer gravy.
- Keep the pan tightly covered while cooking so the brisket stays moist.
- Brisket becomes tender through time rather than high heat, so do not rush the braising process.
- Let the meat rest before slicing to help retain its juices.
Serving Suggestions
Serve this braised beef brisket with:
- Creamy mashed potatoes
- Roasted carrots
- Buttered egg noodles
- Garlic green beans
- Crusty bread
Storage
Store leftover brisket and onion gravy together in an airtight container in the refrigerator for up to 4 days.
Reheat gently in a covered skillet or 325°F (165°C) oven with plenty of gravy to keep the beef moist and tender.
Leftover Ideas
- Use sliced brisket in toasted sandwiches with melted provolone.
- Shred leftovers and serve over mashed potatoes with extra gravy.
- Add chopped brisket to pasta, rice bowls, or baked potatoes.
FAQs
Can I make brisket ahead of time?
Yes. Braised brisket is excellent when prepared a day ahead. Refrigerate it in the gravy, then reheat gently before slicing and serving.
Can I make this in a slow cooker?
Yes. After searing the brisket and preparing the onions and gravy, transfer everything to a slow cooker and cook on LOW for 8–9 hours.
Why is my brisket still tough?
It usually needs more cooking time. Continue braising until the connective tissue softens and the meat becomes fork-tender.
Can I add mushrooms?
Yes. Sliced mushrooms can be sautéed with the onions for an even richer gravy.
