Say goodbye to ho-hum sides. These simple caramelized peppers and onions are slightly sweet, deeply savory, and packed with flavor!
There’s something almost magical about sautéing peppers and onions. The peppers go from crisp and fresh to soft, silky, and lightly charred, while the onions mellow out and caramelize, losing their sharp bite. It’s a simple combination, but so satisfying. This dish is the perfect side for steak, spicy Italian sausage, or a bowl of warm, creamy polenta.
“This was sooo good! I have made the classic peppers and onions over the years and it was nothing special. This recipe nails it!”
What You’ll Need To Make Caramelized Onions And Peppers
- Extra Virgin Olive Oil: Provides a rich base for sautéing, enhancing the natural sweetness of the onions and peppers.
- Yellow Onion: Caramelizes as it cooks, adding deep, sweet, and savory flavor to the dish.
- Bell Peppers: Bring a vibrant pop of color, natural sweetness, and a tender bite.
- Balsamic Vinegar: Introduces a touch of acidity and sweetness, brightening the whole dish.
- Fresh Thyme: Adds an earthy, aromatic note that complements the sweetness of the vegetables. Dried thyme will work here as well.

Step-By-Step Instructions
Heat the oil in a large skillet over medium-high, then toss in the onions and peppers, sprinkling on the salt and pepper as you go. Turn the heat down to medium-low and let them cook, stirring often, until the onions are caramelized and the peppers are soft and slightly browned—this should take 15 to 20 minutes. If you notice a brown layer forming on the bottom of the pan, just add a splash of water and stir it in, repeating as needed. Once everything looks beautifully golden, add the balsamic vinegar and thyme.
Turn the heat down to low, give everything a good stir, and let it cook for a few more minutes. Taste and add more salt or pepper if needed. Serve warm or at room temperature—either way, it’s delicious!

Has anyone made this and added jalapeno?
Not as far as I know.
Hi Jenn – I made these and they were fanrastic. I have a wood fired pizza oven and used these as a topping with fontina cheese and my homemade pizza sauce. I made three different pizzas that night and my guests all agreed that the one with the onions and peppers was the best.
Made it last night and it was the best peppers and onion recipe I have found.
Making this for the second time to go with the Moroccan chicken tangine. They are great together.
