You won’t believe how easy these slow cooker brats are. Crockpot beer brats are made with just 6 ingredients and are flavorful and juicy!


  • 1 onion, sliced into half moons
  • 4 cloves garlic, smashed
  • 10 brats
  • 1 cup beer of choice
  • 2 Tbsp. grainy mustard
  • 1 tsp. caraway seeds


  1. Prep ingredients: 
    Slice onions. 
    Smash garlic. 
    Layer onion and garlic in the bottom of the slow cooker.

  2. Heat oil in large skillet. Brown brats for about 1-2 minutes per side, just until browned. (They don’t need to be cooked through!) Nestle brats on top of the onions and garlic.

  3. Combine beer, mustard and caraway seeds in a small bowl. Season with salt and pepper and pour over brats and veggies.

  4. Cook on high for 2 hours, or low for about 4 hours, or until brats are cooked through.


  • Use a pilsner or IPA beer.
  • Dijon mustard can also be used in place of grainy mustard.
