Ingredients

For the Beer Brats

• 3 pounds bratwurst sausages, about 10 to 12 brats
• 2 large yellow onions, sliced into thick half-moons
• 3 bottles lager or light beer, 12 ounces each

That’s all you need to create this easy and satisfying slow cooker meal.

How to Make Slow Cooker Beer Brats

Step 1: Add the Onions

Start by placing the sliced onions in the bottom of a large slow cooker.

Spread them out evenly to create a layer underneath the sausages. As everything cooks, the onions will soften and absorb the delicious flavors from the bratwurst and beer.

Step 2: Add the Bratwurst

Place the bratwurst sausages directly on top of the sliced onions.

Arrange them in a snug layer inside the slow cooker. A little overlapping is completely fine, especially when cooking a large batch.

Step 3: Pour in the Beer

Slowly pour the beer over the bratwurst and onions.

The sausages should be mostly surrounded by the liquid, although they do not need to be completely covered.

The beer creates a flavorful cooking broth while helping keep the brats moist and juicy during the long cooking process.

Step 4: Slow Cook

Cover the slow cooker with the lid.

Cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours.

The bratwurst should be fully cooked and plump, while the onions should become very soft and tender.

Step 5: Brown the Brats (Optional)

For extra color and a more traditional grilled appearance, remove the cooked bratwurst from the slow cooker.

Place them in a hot skillet or on a grill and cook for approximately 2 to 3 minutes per side until lightly browned.

Once browned, you can return them to the slow cooker to keep warm with the onions and cooking liquid.

Step 6: Serve

Set the slow cooker to the WARM setting until you’re ready to serve.

Use tongs to remove the bratwurst and a spoon to scoop up the tender onions.

Serve each brat in a soft brat bun or hot dog bun and add onions and your favorite toppings.

Best Toppings for Beer Brats

One of the best things about this recipe is how easily everyone can customize their own brat.

Try serving your slow cooker beer brats with:

• Yellow or spicy mustard
• Ketchup
• Sauerkraut
• Dill pickles
• Extra cooked onions
• Relish

Set everything out buffet-style so guests can build their own sandwiches.

What to Serve with Slow Cooker Beer Brats

These hearty brats pair perfectly with classic comfort-food side dishes.

Some great options include:

• Potato salad

• Buttered cabbage
• Green salad
• Pickles and pickled vegetables

For a casual party, chips and dips also make an easy addition to the table.

Tips for the Best Beer Brats

Use Thick-Sliced Onions

Cutting the onions into thicker slices helps them maintain some texture during the long cooking time.

They will still become wonderfully soft but won’t completely disappear into the broth.

Don’t Worry if the Brats Look Pale

Bratwurst cooked entirely in a slow cooker may not develop the deep brown color you get from grilling.

They are still delicious and fully cooked.

If you want that golden exterior, simply brown them quickly in a skillet or on the grill after slow cooking.

Keep Them Warm for Parties

This recipe works particularly well for entertaining because the slow cooker can keep everything warm for serving.

Leave the brats and onions in the cooking liquid and allow guests to serve themselves throughout the party.

Variations

Add a Little Spice

If you enjoy spicy food, replace some of the regular bratwurst with hot or jalapeño brats.

This adds extra heat without changing the basic recipe.

Use Different Sausages

Other fully cooked or fresh sausages can also work well with this cooking method.

Try experimenting with different varieties depending on what is available at your grocery store.

Add Potatoes

For a more filling meal, place parboiled potatoes or baby potatoes in the slow cooker before adding the onions and bratwurst.

The potatoes will absorb some of the flavorful cooking liquid and make a delicious side dish.

Beer-Free Option

If you prefer not to use beer, chicken broth can be used instead.

A combination of apple juice and water can also create a slightly sweeter alternative.

Make-Ahead and Storage

These beer brats are great for parties because they can be prepared ahead of time.

Once cooked, keep them warm in the slow cooker until serving.

Store leftovers in an airtight container in the refrigerator along with a little of the cooking broth.

They can be reheated gently in a saucepan over low heat.

Adding a small amount of the broth while reheating helps keep the bratwurst moist.

Leftover Ideas

Don’t let leftover beer brats go to waste.

Slice the sausages and use them in:

• Hoagie sandwiches
• Potato dishes
• Rice bowls
• Pizza
• Breakfast skillets
• Sandwiches with sautéed onions

The tender onions can also be used as a flavorful topping for potatoes or sandwiches.
