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.

Delicious and so easy to make! We cut these in half to go with other dishes that we made. Will be making this recipe again!
After trying this recipe, I will never cook peppers and onions any other way. I’ve made this with brat, Turkey sausage, Italian sausage, you name it. My fiancé and I are obsessed!!
Excellent and easy! Definitely would make it again. Thank you for sharing your recipe.
This is my favorite recipe for brats, but I put everything in a large bowl and mix with the viniagrette then spread everything on the pan and bake as directed. (I also cut the brats in half and serve on a dinner roll as sliders). So easy and delicious.
Bell peppers were on sale and I immediately thought I would make this again. Costco had brats at a decent price, too (package of 14!). So I tripled the dressing and used 8 peppers and a ginormous red onion. I used two rimmed sheets and rotated them up/down and back/front when I stirred and flipped the brats. I cooked them 50 minutes, (20, 20, and 10 minutes).
I know freezing is not recommended. However, I’ve cooked with the bags of frozen peppers. They will have a mooshy texture, and they will taste fine. And, in a bun, it’s not going to matter much.
I’m from Wisconsin where brats are a summertime tradition and I’ve honestly never had a brat that wasn’t grilled before making this, but this was DELICIOUS! And so so easy. Definitely becoming a staple for wintertime when we can’t break out the grill.
Delicious… what I loved most about this recipe. My daughter is not into pepper or a buns. Simple enough, hers came out early. Served this with corn and tater tots. Made me the hero for the night!
I found myself with leftover hot dog buns and bratwurst that was mistakenly picked up instead of Italian sausage. This recipe has been in the queue so I figured it was about time. What a shame I waited so long. I made it exactly as written and was blown away. My toddler who typically doesn’t eat meat ate an entire bratwurst link. Adding this to the rotation and will try some of the suggestions in the comments! Thanks for a wonderful recipe!!
I’ve used this recipe many times and passed it on to friends. It’s easily doubled and is great for entertaining. Very easy to prepare, delicious and inexpensive—I LOVE this great recipe!
Never roasted brats before… This recipe was spot on! Brats, were juicy 😋. Spice level was perfect 😋
What could I use instead of red wine vinegar? ACV or balsamic maybe ?
Apple cyder vinegar would be a great sub!
The vinaigrette is SO GOOD. This recipe really takes a simple bratwurst to the next level!
This recipe is absolutely delicious and a go to for our family now!! It is very easy and the kids love it as much as the adults. Do you think the brats and onions and peppers could be mixed with the vinaigrette and kept in the fridge overnight before baking?
A favorite on our menu. We serve it w/o cheese and bun; instead, we serve it with a side veggie.
Totally fabulous and easy way to make brats and peppers. This is now my go to recipe! We don’t do the cheese or buns. Serve with pierogi or mashed potatoes with a side of beer braised sauerkraut. Everyone loves this. Thanks so much!
Since I sam from Germany…I use the mustard’s we are used too in Germany when making Bratwurst; Düsseldorf (Sweet/Sour) or Bavarian Sweet.
I use Brötchen or Chicago hard roll’s instead of hot dog bun’s to keep it authentic.
Just a note: Brat or Braten in German mean’s Roast or Fry. So when American’s say “I am going to throw some “Brats” on the grill”…it mean’s “I am going to throw “Roast or Fried” on the grill”. The “Wurst” mean’s Sausage and is the Noun.
Can this be made with knockwurst? Our grocery order subbed bratwurst for knockwurst :/
Yes :)
I needed something different than burgers and this was perfect. Even better cause it baked all on one pan. We top ours with spaghetti sauce and cheez-wiz because that’s how I have always had them but they came out great. Thanks!
I love this recipe. I’ve made it several times and it is such a hit in my house.
Tonight I made a variation of this recipe using Italian sausage links and mozzarella and provolone cheese (without the vinaigrette of course!). We topped our buns with some homemade marinara sauce as well and it was delightful!
Thanks for the inspiration, Beth!
I absolutely love sauerkraut, relish, onion, and brown mustard on my brats!!!
Thanks for a tasty, healthier alternative!!!
I commented this morning and gave it 4 stars with 4 1/2 in the comment. It was a little sweet. I used cheddar and pepper brats tonight and accidentally dumped in too much black pepper; I scooped a lot out but was still heavy on the pepper. So good! I only had half a large onion and a little cauliflower this time. I used spicy brown mustard both times. Seemed there was more sauce after cooking tonight.. I will make it again.
Our hoagie buns were way too big for the brats. I sliced the brats on the diagonal into wide slabs and it worked great. Those buns were stuffed and we ate well!
Yum! I wanted to grill brats, but the grill is covered with snow. Tried this tonight and loved it. I made with without cheese making it a dairy, egg free option for a family member I served it with some Trader Joe’s =Stone ground mustard. Thank you .
Our favorite recipe from your website – hands down! And we’ve tried MANY of your recipes. They are all delicious! Thanks for sharing.
That makes us so happy to hear Amy! Thanks for sharing.
Great recipe! Easy weeknight dinner.
What size dish are you using? Everything fits so nicely!
It’s this 9×11″ roasting pan. :)
My new go to recipe. This is so good!!
Thanks Jill! Happy to hear it.
My first time doing this recipe and WOW everyone went yummy yummy yum! !!!
This recipe is quick, simple, easy and delicious!! I love making this on busy weeknights. Thank you, Beth!
I’ve made this twice now and it’s so good. Very easy to make and my husband loves this. I used to pan fry my brats but never again this is the only way from now on. Can’t wait to tr yg the sausage and cabbage recipe next!
This recipe is simple, easy and delicious. My family loved it.
I love easy meals like this. I doubled the vinaigrette and added four potatoes and a couple Anaheim chiles from the garden.. We ate it in bowls, without the buns.
That sounds amazing. We’re totally making it that way!
Nelly I would love to receive some of your favorite brats recipes i enjoy trying new recipe especially the ones that comes from long ago
This recipe was great! I think next time I might add some red pepper flakes to the vinaigrette to give it just a little spice.
Hello, I’m from Germany and the Bratwurst came from us. We eat this with Sauerkraut and potatoes, but only to christmas (in our department, we called the Bratwurst “Roster” in eastgermany). the Bratwurst alone we eat this to a barbecue and every Time in the year. The best Bratwurst are made in the federal State Thüringen! When You are interested I can give you any old german recipes :)
My mom was from Hamburg Germany and used to make pig ears. They were donuts shaped as pig ears best recipe ever. Do you know the recipe? We lost mom two years ago.
doubled the recipe, had a large group coming. cooked them initially to 22 and second time to 23 cos i forgot! some of the veggies were a bit burnt. next time i will keep it 20/23. I transferred them to a crockpot and set the dial on warm. well that part completely made those onions and pepper melt. Used some sweet hot dog buns and by god the tastes were incredible. I hadn’t had a good brat like that in a long time. my mother even commented the onions were “perfect”. the drippings were a big greasy, but im assumning that’s from the brats and not the olive oil used in the vinagrette.
Yum! Absolute perfection!
Winner! Like others, I used the precooked brats. Twenty minutes was enough time to fully cook everything when sliced very finely. We left the cheese off and it was still delicious, this is going in our favorites.
Ooooh maan and woman and child…I come from the land of bratwurst and
1) they don’t look that good here
2) NOBODY cooks them into something so delicious looking.
It’ like it’s too much..and even cheese on top!! I never considered bread with stuff inside a meal (it’s cultural) but that has to be the one dish to change my opinion forever.
I doubled the recipe and it turned out excellent. Cooked it about an extra 20 minutes. The brats still got good browning on them. It prolly was still done in the normal time but the extra 20 gave a little bit color on everything.
I got bratwursts that say fully cooked on the package- do I still need to roast for same amount of time?
I would only cook them until they brown on the outside. Since they’re already cooked they may dry out if they stay in the oven the entire time.
It never occurred to me to roast sausages. This is an excellent recipe, could easily be adapted for Italian sausages with the addition of Italian herbs and (maybe) skipping the mustard. Thanks!
Like the idea of oven roasting it all together. For our family sauerkraut is a must with bratwurst!!
This was great! I really love it for the technique – somehow I’ve never thought to roast sausage, peppers and onions all on one pan. I’ve always done it either in separate saute pans on the stove or on the grill, but this is so much easier, and still delicious! The sausage still browns, and the peppers and onions soften up so it’s easy to bite through them instead of pulling them out of the bun every time you try to take a bite. The mustard vinaigrette added some flavor to the peppers and onions, but I think I might increase the mustard next time for a little more zing. I think this roasting technique would also work well with Italian sausages, though I’d probably leave out the mustard for that one. Thanks for another easy and delicious recipe, Beth!
I agree that cheese isn’t necessary, and I love the roasted peppers and onions. We don’t do brats often and I usually serve them with sauteed onions and mustard only. I love the roasted vs grilled option. I’ll add some garlic cloves and a sliced poblano pepper to the roasting pan–just a little spice. I’ll also double the mustard in the vinaigrette. My supermarket sells fresh chilis for $2.29 per lb, and since I don’t always check the slip closer, was surprised to notice that a fresh poblano and all of its bright flavor and color usually costs me less than $.50 (week after week they appear on the receipts at 32-39 cents). This looks like a perfect Saturday night supper–fast and easy after a day spent with errands, chores, and family
I love that baking pan! Where did you purchase it?
I got it online from a store called Rove and Swig. They have all sorts of cool enamelware! :)
I am 60 and still learning to cook. For budget reasons as you said in your bio. My sister inspired me with a picture of roasted bratwurst she made. Bratwurst was on sale as were all the colors of peppers. I found your recipe. So good. Company worthy good. Thank you so very much. I am going to look at your other recipes now.
This looks so delicious!
