How to make smoked brisket sandwiches
For full measurements and a printable recipe, see the recipe card below. Key steps:
- Make the pickled red onions: Thinly slice a red onion and halve some garlic cloves. Place onion, garlic and whole peppercorns in a jar, cover with white vinegar and chill for at least 30 minutes.
- Prep the buns: Slice rolls and, if you like, brush the inside lightly with barbecue sauce.
- Warm the meat and buns: Add 2–3 slices of brisket to each bun and place in the oven at low heat (about 200°F / warm setting) for roughly 10 minutes to heat through and toast the bread lightly.
- Assemble: Top warmed brisket with pickled red onions, pickles, fried onions and jalapeño slices. Add coleslaw and extra BBQ sauce on the side if desired.
Substitutions and variations
- Try different bread: brioche buns, pretzel rolls or ciabatta for a different texture.
- Swap the protein: pulled pork or smoked turkey work well with the same toppings.
- Adjust the heat: omit jalapeños or use milder banana peppers if you prefer less spice.
Serving suggestions
Sides: Serve with barbecue sauce and coleslaw. French fries, onion rings, corn on the cob, mac ’n’ cheese, roasted Brussels sprouts or steamed vegetables also pair nicely.
Salads: Potato salad or a pasta salad make excellent sides if you want a lighter contrast.
How to store BBQ brisket sandwiches
Refrigerate: Store leftover components in airtight containers. Assembled sandwiches tend to get soggy, so keep meat, pickles and pickled onions separate and assemble just before serving. Use within 2 days for best quality; pickled onions will last 3–4 days.
Freeze: Freezing assembled sandwiches is not recommended.
Top tips
Toast the buns: A quick toast helps prevent sogginess and adds crunch.
Make ahead: Pickled onions can be prepared several days in advance.
Double the batch: Easy to scale up for a crowd or for meal prep.
Brisket sandwich FAQs
Reheat sliced brisket gently in a 200°F oven until warmed through, or heat briefly in a skillet over medium heat with a splash of beef broth to keep it moist.
Plan on about 3 to 4 ounces of sliced brisket per sandwich when serving with sides.
Smoking time varies, but a common guideline is 30 to 60 minutes per pound depending on temperature and smoker. Larger briskets require many hours, so start early.
