Smoked Brisket Flat
Lean, flavorful, and juicy - the flat may be "the skinny" of the brisket, but with the right moisture tricks it becomes the star of the table.

This recipe uses
Old No.2 Brisket Rub
Robust formula for brisket and pork butts. More spice, larger pieces, less sugar. One 2lb bag seasons ~30 lbs of meat.
Shop Old No.2 Brisket Rub →Ingredients
- TexasBBQRub Old No. 2 Brisket Rub 2 1/2 cup (about 8 oz)
- Worcestershire sauce 1/4 cup
- Olive oil (or other neutral oil) 2 Tbsp
- Liquid smoke (optional, for extra depth) 1 Tbsp
- Apple cider vinegar 1/4 cup
- Beef broth or water (for the water pan) 1 qt
- Thick-cut bacon strips 6-8 strips (optional for added fat)
- Whole grain mustard (for a thin binding coat) 1 Tbsp
- Freshly cracked black pepper 1 tsp
- Salt (kosher) 1 tsp
- Wood chips/chunks - oak, hickory, or a 50/50 oak-mesquite mix 2-3 lb
Instructions
- Trim & Inspect: Remove any hard, silvery "deckle" fat and trim the fat cap to about 1/4 inch. Leave the marbled intramuscular fat - it's the secret to moisture.
- Oil & Bind: Lightly brush the meat side with olive oil, then spread the mustard. This thin film helps the rub adhere and creates a modest moisture barrier.
- Rub It Good: In a bowl, mix TexasBBQRub Old No. 2 with the salt, pepper, and Worcestershire sauce. Pat the mixture onto the meat side until it forms a paste-like coating. If you have time, let the brisket sit, loosely tented with foil, for 30 min to an hour.
- Add Fat (Optional but Recommended): Lay the bacon strips over the rub-coated meat, overlapping slightly. The bacon will melt into the flat during the long smoke, supplying needed fat.
- Pre-heat the Smoker: Set the smoker to a steady 225 degrees F (107 degrees C). Use a combination of oak and hickory, or a 50/50 oak-mesquite mix for classic Texas flavor. Add a water pan with 1 qt beef broth to keep the cooking chamber humid.
- Smoke the Flat: Place the flat fat side up on the grate (fat will baste the meat). Insert a probe thermometer into the thickest part. Smoke until internal temperature reaches 165 degrees F, then proceed to the "wrap" stage (see step 7). Total time to this point is usually 5-7 hr.
- Wrap for the Stall: Remove the flat, discard excess bacon if desired, and wrap tightly in two layers of heavy-duty aluminum foil (or pink butcher paper). Return to the smoker, maintaining 225 degrees F.
- Finish Cooking: Continue smoking until the internal temperature hits 195-203 degrees F and a probe or fork slides in with little resistance (the "probe test"). This typically adds 2-4 hr beyond the wrap.
- Rest & Slice: Let the wrapped brisket rest for 30-45 min (still in foil). Then unwrap, slice 1/4-inch strips across the grain, starting at the flat end and adjusting the knife as the grain direction changes.
- Serve: Serve hot with your favorite BBQ sauce (or plain - TexasBBQRub does the heavy lifting). Offer pickles, onions, and white bread on the side.
Bill's Pitmaster Tips
- Bacon Fat Shield - Drape bacon on the meat side before the rub.
- Steam-Boost Water Pan - Fill the pan with beef broth and keep the lid slightly ajar.
- Temperature Swing Test - If the internal temp stalls at 165-170 degrees F for more than an hour, increase the smoker to 250 degrees F for 30 min, then drop back to 225 degrees F.
