Tested & Perfected Recipes

caramelized onions

Eaten raw, bell peppers are sweet and crunchy yet when cooked, they become tender, luscious and – in this case – ever so slightly charred.  The same goes for the onions, which start off sharp and pungent, but transform into sweet caramel-colored ribbons. Try this dish with steak, spicy Italian sausage or on top of a bowl of hot and creamy polenta.


Caramelized Onions and Bell Peppers

Onions and bell peppers transformed into sweet caramel-colored ribbons. Delicious with steak or spicy Italian sausage.

Servings: 4
Total Time: 25 Minutes


  • 2 tablespoons extra virgin olive oil
  • 4 bell peppers, stemmed, seeded and cut into 1/4-inch strips
  • 1 large yellow onion, peeled and sliced into 1/4-inch strips
  • 1/2 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper
  • 2 teaspoons balsamic vinegar
  • 1 teaspoon fresh thyme, finely chopped (or 1/2 teaspoon dried thyme)


  1. Heat the oil in a large skillet over medium-high heat. Add the onions, peppers, ¼ teaspoon salt and ¼ teaspoon pepper.
  2. Cook, stirring every few minutes, until onions are caramelized and peppers are tender and slightly browned, about 15 - 20 minutes.
  3. Add balsamic vinegar and thyme and turn heat to low. Cook for a few more minutes. Taste and add remaining salt and pepper if desired. Serve hot or at room temperature.

  • Perfect with Prime Rib Roast. I opted not to add the balsamic vinegar and we really enjoyed the flavor. This is a simple and easy side that would compliment any barbecued meal.

  • I buy a 3-pepper blend, frozen, in Kroger. Can your recipe be frozen safely and used as needed? I use it to make omelets. Thanks!

    • Hi Paul, I’ve never frozen these, but I think it would be perfectly fine.

  • Thanks. I have used this recipe multiple times since I happened upon it. I often eat this with grilled lamb – either backstraps or loins, and a good Mediterranean salad that has to include olives and feta. If you can add some good homemade hummus, even better. Cheers.

  • Holy delicious! I put this on a chicken burger with guacamole and it was amazing.

  • I have been wanting to try a pepper, or capsicum as they are called here in New Zealand, recipe forever- I’m so glad I tried this one. So good!! Already planning when I can make it again. Just working my way through the whole site since every recipe Jen does is the bomb. Thanks for doing what you do!

  • I added garlic and poblano to this and it was gorgeous! I also drizzled with olive oil after which gave it a wonderful fresh pop.

    Love it! Thank you!

  • Having the best year ever for my garden – lots of peppers. Love the bright colors & flavor of this dish. We enjoyed it with some grilled chicken – perfect summer meal. Just can not beat the fresh flavors of home grown!

  • So simple and so good.

  • I had this last night with Grilled Salmon. What a Treat..Just right and pleasing to the eye as well as the palett
