First, this will be cooked again at our house. It was very good. I came across this recipe on A Soft Place to Land. It was a 5 star for taste, prep, leftovers in our opinion.

Here is what you need:

4-5lb brisket (not corned beef brisket) Do NOT trim the fat off. You want it to soak up the flavor.
1/4 teaspoon celery salt
1/2 teaspoon garlic salt
1/2 teaspoon onion salt
1/4 teaspoon salt (all this salt makes it good. Not salty)
1.5 oz bottle of liquid smoke
BBQ sauce

1. Sprinkle seasonings over your brisket.
2. Pour liquid smoke over seasoned brisket.
3. Cover and refrigerate for at least 8 hours
4. Preheat oven to 275 degrees.
5. Place brisket in covered pan and place in oven.
6. Cook for 3-4 hours or until fork tender.
7. Slice thinly, across the grain.
