Ingredients for Slow Cooker Beer Brats
You only need a few simple ingredients for big flavor:
The Meat and Veggies:
6-8 Uncooked Bratwursts: Look for high-quality fresh bratwursts (like Johnsonville). Do not use pre-cooked sausages; they won’t absorb the flavor as well.
2 Large Onions: White or yellow onions work best. Sliced into half-moons, they cook down into a sweet, savory topping essential for the classic experience.
The Braising Liquid:
2-3 cans (24-36 oz) Beer: A standard American lager or pilsner is traditional. For a deeper flavor, try an amber ale or stout. If you prefer to avoid alcohol, beef broth or non-alcoholic beer works too.
Garlic & Butter: Minced garlic adds aromatic depth, while a pat of butter rounds out the sauce and adds richness to the onions.
Step-by-Step Instructions
Slice onions into half-moons and mince the garlic. Uniform slices ensure the onions cook into a perfect topping.
Layer onions and garlic in the bottom of the slow cooker, then arrange bratwursts on top.
Pour beer over the mixture until brats are mostly submerged, then add butter and pepper.
Cover and cook on LOW for 5-6 hours or HIGH for 2-3 hours until onions are soft.
Slow Cooker Beer Brats (Tender & Juicy)
Equipment
- 6-quart slow cooker, sharp knife, cutting board, tongs, outdoor grill or grill pan (optional for finishing)
Ingredients
Instructions
- 1
Slice the onions into uniform half-moon shapes. This ensures they cook down properly into a soft, flavorful topping without disappearing completely into the sauce.
- 2
Place the sliced onions and minced garlic at the bottom of your 6-quart slow cooker. Arrange the uncooked bratwurst links in a single layer (or slightly overlapping) on top of the onions. Do not pierce the sausages.
- 3
Pour the beer over the bratwursts and onions. The liquid should mostly cover the meat. Add the butter and sprinkle with black pepper. The butter will melt down and add a rich, velvety finish to the beer sauce.
- 4
Cover and cook on LOW for 5-6 hours or HIGH for 2-3 hours. The brats should be cooked through (internal temperature of 160°F) and the onions should be soft and translucent.
- 5
Preheat your grill to medium-high heat (about 400°F). If you don't have a grill, you can use a cast-iron skillet on the stove or the broiler setting in your oven.
- 6
Remove the brats from the slow cooker with tongs. Grill them for 2-3 minutes per side, just long enough to get nice char marks and crisp up the casing. This step adds texture and the classic "snap."
- 7
While the brats grill, lightly toast the buns on the grill or in the oven. This prevents them from getting soggy when you add the juicy toppings.
- 8
Serve immediately by placing a grilled brat in a toasted bun. Use a slotted spoon to scoop the beer-braised onions from the slow cooker and pile them on top. Finish with spicy mustard or sauerkraut.
Notes
If you don’t consume alcohol, you can substitute the beer with an equal amount of low-sodium beef broth, chicken broth, or even apple juice for a sweeter twist. The flavor profile will change, but the brats will still be tender.
For the best results, avoid dark stouts or heavily hopped IPAs as they can turn bitter during the slow cooking process. Stick to Pale Ales, Lagers, or Pilsners.
This recipe is perfect for parties. You can return the grilled brats to the slow cooker (turn setting to WARM) to keep them hot for guests. Just make sure to drain a little liquid if it’s too full.
Pro Tips for Perfect Slow Cooker Beer Brats
Make your game day food legendary with these expert tips:
- Don’t Skip the Sear: While the slow cooker makes them tender, a quick sear on the grill or in a skillet after slow cooking gives them that appetizing color and irresistible “snap” when you bite in.
- The Right Beer Matters: Use a beer you enjoy drinking. Light lagers provide a classic taste, while IPAs can make the onions bitter as they reduce.
- Toast Your Buns: A sturdy, toasted bun is crucial to hold the juicy brat and toppings without falling apart.
- Piercing is a Myth: Do not pierce the casings before cooking! This lets all the delicious juices run out, leading to dry meat.
Serving Suggestions & Variations
Serve these juicy beer brats on sturdy hoagie rolls or brat buns.
Classic Toppings:
- The beer-braised onions from the pot (drain them slightly first)
- Spicy brown mustard or stone-ground mustard
- Sauerkraut (rinsed and warmed)
Variations:
- Spicy Kick: Add sliced jalapeños or red pepper flakes to the slow cooker.
- Cheesy Brats: Top with shredded cheddar or melt a slice of provolone over the hot brat.
Storage and Reheating Instructions
Storing Leftovers: Store the cooked brats and onions together in an airtight container with a little bit of the cooking liquid. They keep in the refrigerator for 3-4 days.
Reheating: Gently reheat in a saucepan over medium-low heat or back in the slow cooker until warmed through. You can also microwave them, but the texture is best when warmed gently in liquid.
Freezing: You can freeze the cooked brats in the liquid for up to 2 months. Thaw overnight in the fridge before reheating.
