Now it’s one of my favorite easy comfort meals because it takes very little work but tastes like something from a restaurant.

Why This Recipe Works (Quick Science)
Slow cooking lets the bratwurst gently heat in the beer without drying out. The beer adds deep flavor while the onion slowly softens and releases sweetness. Finishing the brats in a hot skillet creates a browned crust through caramelization, which adds even more flavor and texture.
Pro Tips
- Don’t poke holes in the brats or the juices will leak out
- Use a mild lager beer for the best balanced flavor
- Sear the brats after slow cooking for better texture
- Toast the buns for extra crunch and flavor
- Let the onions cook the full time so they become soft and sweet
Substitutions and Variations
- Use chicken brats instead of pork brats
- Swap lager for non-alcoholic beer
- Add sliced bell peppers
- Use pretzel buns for extra flavor
- Add shredded cheese on top before serving
Make Ahead Tips
You can place the brats, onion, garlic, butter, and beer into the crockpot insert the night before. Cover and refrigerate overnight. In the morning, place the insert into the slow cooker and start cooking.
Slow Cooker Beer Brats Recipe
Step 1: Add Everything to the Slow Cooker
Place 6 raw bratwurst sausages into the black oval crockpot. Add 1 large sliced onion, 3 minced garlic cloves, 2 tablespoons butter, 1 teaspoon salt, and 1 teaspoon black pepper. Pour in 2 bottles of lager beer until the brats are mostly covered.
Step 2: Cook on LOW for 5 hours.
Step 3: Remove the Brats
After 5 hours, carefully remove the cooked bratwurst from the crockpot using tongs. The onions should be soft and the beer liquid slightly darker.
Step 4: Brown the Brats
Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the cooked bratwurst and sear for 2 to 3 minutes per side until deep golden brown.
Step 5: Toast the Buns
Place the 6 brat buns cut side down into the skillet for about 1 minute until lightly toasted.
Step 5: Assemble the Beer Brats
Place each browned brat into a toasted bun. Top with soft cooked onion, whole grain mustard, and sauerkraut if desired.
