Why You’ll Love It

Timing and Servings

• Prep: 15 minutes
• Caramelize Onions: 20–25 minutes
• Simmer & Bake: 30–40 minutes
• Total: about 1 hour
• Serves: 6 people

Ingredients

• 6 bratwursts (pork, chicken or turkey—choose your favorite)
• 2 large onions, thinly sliced (yellow or sweet)
• 2 cloves garlic, minced
• 1 tbsp olive oil
• 2 tbsp butter
• 12 oz beer (lager, pilsner or a mild IPA)
• 1 cup beef broth
• 1 tbsp Dijon mustard
• Salt and pepper, to taste
• Chopped fresh parsley, for garnish (optional)

Directions

1. Preheat your oven to 350°F (175°C). Grab a large, oven-safe skillet or Dutch oven—cast iron works beautifully for that seared-on flavor.
2. Warm the olive oil and butter over medium heat. Add sliced onions, stirring now and then. Patience pays: let them soften and turn golden, about 20–25 minutes. You’re aiming for a rich, sweet color with a touch of caramel at the edges.
3. Stir in minced garlic for 2–3 minutes until fragrant. It’ll smell so good you’ll want to dive right in—but resist, because the next step is key.
4. Tuck the bratwursts among the onions—no pre-browning needed. They’ll absorb all that sweet, buttery onion flavor as they cook.
5. Pour in the beer and beef broth, then whisk in the Dijon mustard. A little stir helps everything come together. Season lightly with salt and pepper, keeping in mind the broth and sausage will also add saltiness.
6. Bring the mixture to a gentle simmer on the stove. You should see small bubbles rising around the sausages. Once that happens, slide the skillet—uncovered—into the oven.
7. Bake for 30–40 minutes. The sausages will swell, the liquid will reduce slightly, and the aroma will go through the roof. Use a meat thermometer if you like—140°F internal temp means they’re perfectly done.
8. Remove from oven and let rest for a couple of minutes. Scatter chopped parsley over the top for a fresh pop of color and flavor.
9. Serve straight from the skillet alongside mashed potatoes, roasted veggies, pretzel rolls or crusty bread to soak up that saucy goodness.

Variations

If you feel like jazzing things up, try one of these simple tweaks:

• Bell Peppers: Add sliced red and yellow peppers alongside the onions for extra color and mild sweetness.
• Spicy Kick: Sprinkle in red pepper flakes or swap to a hoppier IPA for a bit of heat that lingers.
• Sweet Twist: Stir a spoonful of brown sugar or honey into the braising liquid—because why not?

Storage & Reheating Tips

Leftovers will keep in an airtight container in the fridge for up to 4 days. The onions and sauce actually taste better day two, when those flavors have mingled even more.

To reheat, transfer brats and onions to a skillet, cover, and warm over medium-low heat until heated through. If the sauce seems too thick, splash in a bit of water or broth to loosen it up.

You can also freeze portions for up to 3 months. Thaw overnight in the fridge, then reheat as above.

FAQs

Can I brown the bratwursts first?
You can, but it’s not necessary. Skipping this step lets the sausages soak up more onion goodness—and halves your hands-on time.

What’s the best beer to use?
Light lagers or pilsners keep the focus on the sausage and onions. A mild IPA works too if you like a bit of bitterness. Avoid super-dark stouts—they can overpower the dish.

Can I make this on the stovetop?
Sure—just cover the skillet after step 5 and simmer over low heat for 30–40 minutes, stirring occasionally so nothing sticks.

Any tips for extra-soft onions?
Add a pinch of salt early on to draw out moisture, and keep the heat moderate so they sweat rather than burn.

Conclusion

Cozy, easy, and endlessly adaptable, these oven-braised beer brats with caramelized onions have a way of bringing people together. Whether it’s game night, a crisp weekend dinner or just a moment when you crave something warm and comforting, this recipe’s got you covered.

Ingredients

  

1x2x3x

• 6 bratwursts
• 2 large onions thinly sliced
• 2 cloves garlic minced
• 1 tbsp olive oil
• 2 tbsp butter
• 12 oz beer pilsner or lager works well
• 1 cup beef broth
• 1 tbsp Dijon mustard
• to taste salt and pepper
• as desired fresh parsley chopped, for garnish

Instructions

 

• Preheat your oven to 350°F (175°C).
• In a large, oven-safe skillet or Dutch oven, heat the olive oil and butter over medium heat. Add the sliced onions and cook, stirring occasionally, for about 20-25 minutes until the onions are soft and golden brown.
• Stir in the minced garlic and cook for an additional 2-3 minutes until fragrant.
• Nestle the bratwursts among the caramelized onions in the skillet.
• Pour the beer and beef broth into the skillet, ensuring the bratwursts are mostly submerged. Stir in the Dijon mustard, and season with salt and pepper to taste.
• Bring the mixture to a gentle simmer on the stovetop. Once simmering, transfer the skillet to the preheated oven and bake, uncovered, for 30-40 minutes, until the bratwursts are cooked through.
• Remove the skillet from the oven and let the dish rest for a few minutes. If desired, garnish with chopped fresh parsley before serving.
• Serve the bratwursts with your choice of side, such as mashed potatoes, roasted vegetables, or crusty bread.

Notes

For a deeper beer flavor, use a darker beer like a stout or porter to intensify the dish’s richness. If you don’t have an oven-safe skillet, transfer the mixture to a baking dish after simmering and proceed with baking.
