I love how easy this is, and that all 5 of us love it for dinnertime. You see I grew up with a very German Grandfather, who took me to the Octoberfest in his city every year. I’m talking he wore his lederhosen, hat with pins from his hometown on it, and we always ate THIS!

The difference is the redder version is spicy and the other is “regular”. It is nice to have both if it is your first go around so your family can see which they like better.

Let’s start with what was cooked here on the same tray. A mixture of sliced red onion, yellow and red bell peppers looked good at the store so that’s that. If you were making Boiled Brats you could just cook the veggies this way too.

Knowing How Long to Cook Sausage in Oven is vital because you always want to ensure the middle is cooked all the way thru of course since these are starting out as raw.

These need to reach the proper internal temperature before consuming to be safe.

How to Cook Johnsonville Brats in Oven

• First you’re going to preheat your oven to 400 degrees F. Slice all of the bell peppers and onions into thick strips. Place these into a bowl.
• Toss all of the veggies with olive oil and salt and pepper. Leave a little oil on the side to drizzle on bratwurst.
• Cover the baking sheet with parchment paper, aluminum foil, or spray with non stick spray. Pour veggies on top in a single layer. Lay meat on top of them. Drizzle remaining oil on meat.
• Bake bratwurst for 25-30 minutes turning meat half way thru cook time.
  • Use a meat thermometer in the middle of the meat to check if it has reached 160 degrees.

If you want to crisp outsides, broil for 2 minutes or so and then serve on buns with pepper mix and mustard. You could use your air fryer or grill brats outside too to get that crispy snap you want. Can take another 15 minutes or so including time to prep this additional step but worth it.

What to serve with brats

The brand really doesn’t matter, most all of them are the same size with 5 in the package so store brands or name brands will take the same cook time. There are a ton of options as far as what to make with them. If you ate this as a child you likely have a MUST in mind but if you need a few suggestions boy do we have them.

• Our Instant Pot fried cabbage is out of this world. We make this with corned beef and these.

To serve, transfer into a casserole dish with hoagie rolls in a basket on the side and all the fixings available. Mustard sauce and our quick sauerkraut recipe is a must.

How to store leftovers

If you have leftovers you can store them in a freezer bag once they are cooled and into the fridge they go. Reheat within 1-2 days in a pan on your stovetop. You can pour a bit of beer in to steam with a lid. Looking for other tips and tricks to make meal time faster? Last week we shared how to cook frozen bacon in the oven, try that too.
