Roasted Bratwurst with Peppers and Onions

Bratwurst is something I only eat once in a blue moon but when I have it, OMG it’s soooo good. When my bratwurst craving came back this time I decided to try a little trick that I discovered with my Roasted Kielbasa and Cabbage Dinner recipe—tossing the vegetables in a vinaigrette instead of just oil and spices. Because I eat my bratwurst with mustard, just like I do my kielbasa, I made the same deliciously tangy stone ground mustard vinaigrette to season my Roasted Bratwurst with Peppers and Onions.

The combination of the tangy vinaigrette and the sweet caramelized peppers and onions made an incredible pairing with the savory bratwurst. This, my friends, is a winner.

How to Serve Roasted Bratwurst with Peppers and Onions

I added more mustard and some cheese as optional toppings in the price break down, but honestly, these puppies are great on their own with just the roasted peppers stuffed into a soft toasted bun. But I’m curious, what do you like to top your bratwurst with? Tell me in the comments below!

How to Store the Leftovers

If you know you’re not going to eat all five brats in one sitting, only stuff fill the buns of the ones you’re going to eat immediately. Package up the remaining roasted bratwurst, peppers, and onions into an air-tight container, and keep refrigerated for up to about 4 days. You can reheat the brats and vegetables in the microwave, stuff into a bun, then enjoy!

What Else Can I Add to My Bratswurst?

I’ve been obsessed with sauerkraut lately, so I like to put a couple spoonfuls of that on top of the peppers and onions, and it’s absolutely divine. Surprisingly, pickled jalapeños are also pretty good on these!

How to Make Oven Roasted Bratwurst – Step by Step Photos

Preheat the oven to 400ºF. In a small bowl stir or whisk together 2 Tbsp olive oil, 1 Tbsp red wine vinegar, 1/2 Tbsp stone ground mustard, 1/4 tsp garlic powder, 1/8 tsp salt, and some freshly cracked pepper.

Slice three bell peppers and one onion into 1/4-inch thick strips. I like to use two green bell peppers because they are less expensive, and one of another color for variety. Place the sliced vegetables on a large baking sheet with five bratwurst links, then drizzle the vinaigrette over top. Toss the bratwurst and vegetables until everything is coated in the vinaigrette.

Roast the bratwurst and vegetables for 20 minutes, then give everything a good stir. Bake for a additional 20-25 minutes, or until everything has browned on the edges.

Stuff the bratwurst, peppers, and onions into the buns. Top with a little shredded cheddar, if you like…

Bake for another 5 minutes, or until the cheese is melted and the buns are slightly toasted. Top with mustard just before serving.
