Pretzel Brat Sandwich on the Pellet Grill | Best Brat Recipe

Big Poppa here. Today we’re taking bratwurst to a place it’s never been before — butter-toasted pretzel buns, jalapeño bacon seasoning, melted cheese on the bottom (yes, the bottom), and a sandwich build that’ll make you rethink everything you thought you knew about grilling recipes. This isn’t just a brat. This is a Papa Brat.

Poppa's Game Plan

This recipe hits every note — savory sausage, a little maple-jalapeño kick from Big Poppa’s Jallelujah Jalapeño Seasoning, buttery toasted pretzel buns, and bright pickled toppings. We butterfly the brat, cook it gently first, then finish it hot for that grilled char flavor. It’s almost a reverse sear… for sausage. That’s how Papa rolls.

It’s bold. It’s balanced. And it’s one of the best BBQ sandwich builds you’ll throw on your pellet grill.

What You’ll Need

Main Ingredients

  • 4 bratwurst sausages
  • Big Poppa’s Jallelujah Jalapeño Seasoning
  • 4 pretzel buns
  • Butter (for toasting)
  • Colby Jack or Cheddar cheese slices
  • Pickled jalapeños
  • Pickled red onions
  • Kewpie mayonnaise
  • Yellow mustard or Japanese mustard
  • Shredded lettuce

Tools & Gear

Step-by-Step: Pretzel Brat Sandwich

  1. Butterfly the Brats: Carefully slice each brat lengthwise without cutting all the way through. Open them flat.
  2. Season: Generously apply Jallelujah Jalapeño to the open side so the seasoning gets inside as it cooks.
  3. Cook Indirect First: Set your pellet grill to medium heat (around 350°F). Place brats open-side up and cook gently until internal temp reaches about 145°F.
  4. Press & Char: Flip brats open-side down. Use grill presses to keep them flat and prevent curling. Cook 3–4 minutes to develop char and grill flavor. Finish at 160°F internal.
  5. Toast the Pretzel Buns: Butter the inside of each bun and toast until golden brown. For a pro move, place hot buns in a sealed bag for a few minutes to steam and stay soft.
  6. Build the Sandwich: Spread mayo on the bottom bun. Add shredded lettuce and cheese. Place hot brat on top. Add mustard, pickled jalapeños, and pickled onions. Crown it and serve.

Serving Ideas

  • Serve with grilled potatoes or kettle chips.
  • Pair with a cold beer or root beer.
