Bratwurst burger ingredients

Here's what you'll need to make these bratwurst burgers:

  • Onion – slow-cooked onions in olive oil which gives the burgers lots of rich, savory flavor.
  • Sauerkraut – this traditional fermented food is full of flavor and healthy gut bacteria, and the sourness works perfectly with the sweet onions.
  • Mayonnaise – light or regular – your choice!
  • German mustard – German mustard is a bit like dijon but with a bit more heat. It's made with different varieties of ground mustard seeds mixed with vinegar, oil, herbs, and/or sweeteners. If you have dijon in your fridge, you can use that instead.
  • Bratwurst sausages – these fresh German sausages are made with pork and veal and seasoned with herbs like ginger, nutmeg, coriander, and caraway.
  • Swiss cheese – this mild and nutty cheese is everything an alpine-style cheese should be!
  • Burger buns – we use pretzel buns in the pictures, but any hamburger bun or brioche bun will work just as well!

How to make these bratwurst burgers with onion sauerkraut topping

These bratwurst burgers are a quick and easy weeknight or pre-game meal. Here's how we make them at home in a few simple steps:

  1. To start, cook the onions until they're soft and starting to brown. Then, mix in the sauerkraut.
  2. We like to mix the mayonnaise and mustard together to make a sauce.
  3. Open the sausages and discard the casings then place the meat into a bowl and crumble it with your hands.
  4. Now, form the meat into four patties.
  5. Grill the patties or sear them in a dry pan. Just make sure they're fully cooked and reach an internal temperature of 165 degrees Fahrenheit. Then, top the cooked bratwurst patties with swiss cheese and warm up the buns.
  6. To serve your burgers, slather the mustard mayo sauce on buns and top with a burger patty and some of the onion mixture.

FAQS

How do I know when the burgers are fully cooked?

Great question! Because these burgers are made with sausage meat (rather than freshly ground meat), it's important that they are fully cooked before you serve them. Use a meat thermometer to make sure they reach an internal temperature of 165 degrees Fahrenheit. 

Can I prepare these ahead of time?

Definitely! To save time, mix together the mustard mayo sauce and prepare the patties. Store them in the fridge in airtight containers for up to 3 days, or until you're ready to cook them.

Can I reheat leftover bratwurst burgers?

Burgers are one of those foods that just don't taste the same reheated. You definitely can, but don't expect the same results. To reheat, place them in the oven at 400 degrees Fahrenheit for about 5 minutes, flipping halfway through.

What to serve with a bratwurst burger

Notes

Bratwurst burgers tend to cause flare-ups when they cook. To help prevent this, make sure your grill is clean before you start. Also, keeping a spray bottle with water handy to tame flare-ups is a good idea.
Because these burgers are made with sausage meat (rather than freshly ground meat), it's important that they are fully cooked before you serve them. Make sure that they reach an internal temperature of 165 degrees Fahrenheit.
