Key Ingredients & Substitutions
Bratwurst Sausage: This is the star of the dish! If you’re looking for a lighter option, chicken or turkey bratwurst works well too. You can also try vegetarian sausages if you prefer a meatless version.
Beer: Any lager or pale ale pairs nicely for flavor. Don’t have beer? You can use non-alcoholic beer or even broth for a similar taste without the alcohol aspect.
Onion: Yellow onions are great for caramelizing, but red onions can also add a nice color and sweetness. Shallots are a tasty alternative if you want a milder onion flavor.
Buns: Brioche buns are soft and buttery, perfect for sliders. If you have dietary restrictions, whole grain or gluten-free slider buns will work, too!
What’s the Best Way to Caramelize Onions?
Caramelizing onions is easier than you think! This step adds amazing depth to your sliders. Here’s how to do it:
- Start with medium heat and use a mix of butter and olive oil.
- Slice your onions thinly and add them to the skillet.
- Cook for about 15-20 minutes, stirring occasionally, until they are soft and golden brown.
- Season lightly with salt to draw out their natural sweetness.
Be patient! Low and slow is key to achieving that beautiful caramelized texture.

- 1 small onion, thinly sliced
- 8 slider buns or small brioche buns

- 2 tbsp butter
- 1 tsp olive oil

- 1/4 cup sauerkraut
- 1 tbsp mayonnaise or mustard-based spread
- Thinly sliced pickled onions or raw shallots

How Much Time Will You Need?
This delicious recipe will take about 30 minutes from start to finish. You’ll spend about 10 minutes preparing the ingredients, 20 minutes to cook everything, and then it’s ready to serve. Perfect for a quick weeknight dinner or a fun gathering!
Step-by-Step Instructions:
1. Prepare the Brat Mixture:
First, remove the casings from the bratwurst sausages and crumble the sausage meat into a medium bowl. Mix it lightly to break it up evenly. This will make it easier to form into patties!
2. Form the Patties:
Next, shape the sausage meat into 8 small slider-sized patties, making each one about 2-3 inches in diameter and roughly 1/2 inch thick. Place them on a plate and pop them in the fridge while you prepare the onions and buns.
3. Caramelize the Onions:
In a skillet over medium heat, add the olive oil and 1 tablespoon of butter. Once it’s melted and hot, add the thinly sliced onions. Cook, stirring occasionally, until the onions are deep golden and caramelized—this should take about 15-20 minutes. Season them lightly with salt for added flavor!
4. Cook the Patties:
While the onions are cooking, heat a grill pan or skillet over medium-high heat. Add the brat patties and cook them for about 3-4 minutes on each side, until they’re nicely browned and cooked through. Yum!
5. Simmer in Beer:
Now, here comes the magic! Add the beer to the pan with the patties, then reduce the heat to medium-low. Let them simmer for 5 minutes, turning occasionally. This way, they soak up all that delicious beer flavor and stay juicy!
6. Toast the Buns:
While that’s simmering, slice your slider buns and toast them lightly in a dry skillet or under the broiler until they’re golden. This adds an extra crunchy texture to the sliders!
7. Assemble the Sliders:
It’s time to put it all together! If you want, spread a little mayonnaise or mustard-based spread on the buns. Start with a layer of caramelized onions on the bottom bun, add a brat patty on top, then finish with sliced pickled onions or raw shallots. You can throw on some sauerkraut too if you like!
8. Garnish and Serve:
Sprinkle a little chopped parsley on the sliders (if you want some color) and serve them up right away with your favorite mustard or dipping sauce. Enjoy!
These Beer Brat Sliders are juicy, packed with flavor, and perfect for sharing—you won’t be able to stop at just one!
Can I Make These Sliders in Advance?
Yes! You can prepare and cook the brat patties and caramelize the onions ahead of time. Store them separately in airtight containers in the refrigerator for up to 2 days. When ready to serve, just reheat the patties and onions, toast the buns, and assemble!
What Should I Do If I Don’t Have Bratwurst?
No problem! You can substitute bratwurst with Italian sausage, chicken sausages, or even turkey sausages. Just make sure to adjust the seasoning if needed, as different sausages may have varying flavors.
Can I Freeze Leftover Sliders?
Definitely! After assembling, you can freeze the sliders wrapped tightly in plastic wrap and then aluminum foil. They should last about 2-3 months. To reheat, bake them in the oven at 350°F until warmed through.
What’s the Best Way to Serve These Sliders?
These sliders are best enjoyed right after assembling! Pair them with sides like potato chips, coleslaw, or a simple salad. You can also offer a variety of mustards and dips for an extra fun touch!
