❓ Q&A
❓ What kind of beer works best?
A mild lager or pilsner is ideal. Avoid very bitter IPAs—they can overpower the dish.
❓ Can I skip browning the brats first?
You can, but browning adds a lot of flavor and better texture. Highly recommended.
❓ Can I make this in a slow cooker instead?
Yes!
- Add everything raw (except pre-caramelized onions if you want extra flavor)
- Cook on low for 6–7 hours or high for 3–4 hours
❓ What sides go well with this?
- Mashed potatoes
- Sauerkraut
- Roasted vegetables
- Crusty bread
❓ How do I know the brats are done?
Internal temp should reach 160°F (71°C).
❓ Can I use non-alcoholic beer?
Yes, it works great and still gives flavor.
❓ How do I store leftovers?
- Refrigerate up to 3–4 days
- Reheat gently on stovetop or microwave
- Flavor often gets even better the next day!
