Ingredients

3-4 pounds beef brisket (flat cut or point cut)
2 (10.5-ounce) cans condensed French onion soup
1 cup beef broth (or water)
Salt and pepper to taste (optional)

Directions

1. Preheat and prepare. Preheat your oven to 325°F (165°C). Choose a large Dutch oven or roasting pan with a tight-fitting lid.

2. Season the brisket. Pat the brisket dry with paper towels. Season generously with salt and pepper on both sides if desired.

3. Add to pan. Place the brisket in the Dutch oven or roasting pan, fat side up. Pour the French onion soup and beef broth over the brisket, making sure it’s mostly covered.

4. Cover and bake. Cover the pan tightly with the lid or aluminum foil. Bake for 3 to 4 hours, until the brisket is fork-tender and easily slices or shreds.

5. Rest and serve. Carefully remove the brisket from the pan and let it rest on a cutting board for 15-20 minutes before slicing. Slice against the grain and serve with the onions and sauce spooned over the top.

Variations

Add vegetables: Place sliced onions, carrots, and potatoes under the brisket.
Garlic lovers: Add 4 cloves minced garlic.
Herb-infused: Add fresh thyme or rosemary sprigs.
Red wine twist: Replace ½ cup broth with red wine.
Mushroom lovers: Add sliced mushrooms during the last hour.
Slow cooker: Cook on LOW for 8-10 hours or HIGH for 4-5 hours.
Shredded version: Shred the brisket and serve on sandwiches.

Expert Tips

Choose the right cut. Brisket needs long, slow cooking to become tender.
Slice against the grain. This makes the meat more tender.
Don’t rush. Low and slow is the key to tender brisket.
Let it rest. Resting allows juices to redistribute.
Save the sauce. Use it as gravy or au jus.

Storage and Reheating

Storage: Store leftovers in an airtight container with the sauce for up to 4 days.

Reheating: Reheat in a 325°F oven for 20-30 minutes or in the microwave.

Freezing: Freeze sliced brisket with sauce for up to 3 months.
