For as long as I can remember, I’ve been a lover of Italian sausage. There’s nothing like that first glorious bite, hot off the grill. A big old Italian sausage sandwich was actually my go-to order at Yankee Stadium when I lived in NYC and went to games. And I especially loved how they piled each sandwich high with onions and peppers with bonus points when I can smother this sandwich in cheese. So it seemed like a good idea to share an Italian sausage sandwich with my own recipe for some awesome sautéed peppers and onions that are slowly caramelized and finished with a little bit of balsamic vinegar, which adds the most perfect tang to contrast with the spicy sausage!

Since I’m a little older and a lot wiser now, I find myself looking for meat options that are not only deliciously flavorful, but super high-quality and more nutritious. Which is a big reason that I’m super excited for my third installment in my collaboration with Shady Brook Farms (if you’re located on the East Coast) and Honeysuckle White (if you live in the Midwest and on the West Coast).

Shady Brook Farms Hot Italian Turkey Sausage Links

Shady Brook Farms turkeys are raised without growth-promoting antibiotics. They along with sister brand Honeysuckle White are the only major turkey brands to exclusively provide family farm-raised turkeys. This effort to help consumers understand
where their food comes from and how it was produced makes me feel good about serving these products to my friends and family.

The wide variety of turkey products that they provide makes it super easy to throw them on the grill and have a versatile and unique meal in no time. They taste awesome by themselves or act as the perfect base for seasoning combinations, flavors and toppings.

They come in a wide variety of delicious flavor, but today I opted to use the Shady Brook Farms Hot Italian Turkey Sausage Links as they add the perfect amount of spiciness without being overwhelming. And the Balsamic peppers and onions compliment the spicy kick from the sausage perfectly!

Tips for how to caramelize onions and peppers

  • Give yourself plenty of time. You want to do this low and slow so that the onions don’t burn for that you’ll need time so that you’ll never have to raise the heat over medium.
  • I start the onions first and then add the peppers.
  • I wait until the last 5 minutes of baking to add the vinegar.

Frequently asked questions about this peppers and caramelized onions recipe

  • Why won’t my onions caramelize? It’s quite likely that your heat is too high. It also takes a good 30-40 minutes to get there, so be patient.
  • How do you cut an onion to caramelize? You’ll remove the root and the skin and then you can cut the onions however you want. The smaller they are, the quicker they’ll caramelize. For this recipe I kept everything to a rough dice to make them easier to eat when you bite into the sausage sandwich.
  • How do you caramelize onions without burning them? Once again, this comes back to using lower heat and stirring often.
  • How dark should caramelized onions be? It really comes down to personal preference, but generally darer than golden. The darker they get the more flavorful they’ll be.
  • Are caramelized onions high in sugar? Although they have a sweeter flavor (because the larger sugar molecules break down during the low and slow cooking) I don’t add additional sugar to this outside of the vinegar at the end.
  • Why are my caramelized onions bitter? Most likely they either burned or the outside cooked and the inside did not- both of these things are due to using heat that’s too high.
  • Can you make caramelized onions ahead of time? Yes, you can make these a couple days ahead and refrigerate until serving.
  • How long do caramelized onions last? Around 3-4 days covered in the refrigerator or a few months in the freezer.
  • How do you reheat caramelized onions? In the microwave or the stove over low heat.

  8. Broil 3-5 minutes or until the cheese is melted (keep a close eye on them so you don't burn them!). Serve immediately.
