Beef Brisket - cooking recipe

Ingredients

1 boneless beef brisket (4 lb.)
2 tsp. salt
1/2 tsp. black pepper
1 tsp. garlic powder
3 large onions, sliced 1/2-inch thick

Preparation

Line a 13 x 10-inch pan with 1 large sheet of foil to cover meat completely later.
Put in brisket, season beef and arrange onion slices on top.
Bake at 350\u00b0 for 1 hour.
When onions brown slightly, then cover (seal) beef tightly with foil.
Add 1 cup of water to pan (may have to add more water).
Reduce heat to 300\u00b0. Cook 2 more hours.
Keep sealed.
After 3 hours, open and check. If fork-tender, it's cooked long enough.
Make gravy from the juices.
