Preheat smoker to 250 degrees Fahrenheit (F) using fruit wood.
Layout bulk ground beef on a sheet tray. Coat with dry rub. And place on smoker for up to 60 minutes or until the larger clumps reach an internal temperature of 160 degrees F.
Chop up the ground beef into smaller pieces and add to the sauce simmer.
For The Sloppy Joe Sauce
While beef is smoking and using a large cast iron skillet over medium heat add olive oil, red onions, and peppers. Stir to soften, but not brown or caramelize. About 10 minutes. Adjust heat down if needed.
Add garlic and stir for additional two minutes.
Add wine and bring to a simmer for 2 minutes while stirring.
Add ketchup, tomato paste, Worcestershire, hot sauce, paprika, dry mustard, and salt, and bring back to a simmer. Simmer for 10 minutes. Add the smoked beef and stir to combine. Cook an additional 10 minutes.
Serve: Spoon the sloppy Joe mixture onto the toasted buns and top with pickles or coleslaw, if desired.
Notes
Ground beef: 80/20 ground chuck provides the best flavor and texture, but leaner ground beef will also work.Smoke: Apple and cherry are my preferred woods. Avoid heavily smoking the beef because the sauce already contains plenty of flavor.Make ahead: The cooked sloppy Joe mixture can be refrigerated for up to 3 days or frozen for up to 3 months.No smoker: Brown the ground beef in a skillet and continue with the recipe as written. Add a little smoked paprika or use a smoky BBQ sauce if you want to mimic some of the smoke flavor.Serving: Toast the buns before serving to help them hold up to the sauce.
