Peperonata (peh-peh-roh-NAH-tah) is an Italian vegetable dish of slow-cooked, or stewed bell peppers with onion and garlic. Of course there are variations and some Italian cooks will add tomatoes, eggplant, or other Italian vegetables. This recipe heightens the flavor of peperonata with an Italian romesco sauce served over a creamy bed of butternut squash.

What is Peperonata?
Peperonata is a southern Italy dish that features sweet summer bell peppers cooked down in olive oil until they’re meltingly soft. The peppers themselves are the star of the show, and while it might include onions and garlic, you do want to keep it simple and let the flavor of the sautéed peppers shine.
Some cooks will add tomatoes or herbs or maybe even a little vinegar, but ultimately the focus is on the peppers.
The traditional way to make peperonata is to cook a couple of cloves of minced garlic with a half of a onion (sliced) in olive oil over low heat for about 10 minutes until translucent. Season with salt and pepper and add 5 or 6 bell peppers that are quartered and of different colors and cook low and slow until the bell peppers are softened.
How to Use Peperonata
The classic Italian way to use peperonata is as a side dish. It is also used as a sort of bruschetta on some toasted bread.
I like following a slow carb lifestyle that includes a lot of protein, so I tend to use pepperonata as a topping for meat or vegetables in a slow carb dinner.
In the recipe below I have used it sautéed with ground beef served with Italian romesco sauce on a bed of butternut squash.

I have also enjoyed the robust flavor of this pepper blend with braised chicken legs as in the photo below:

And keeping with the slow carb diet plan, I had a great meal of peperonata on top of a bunless burger:
Lastly, peperonata could easily add flavor to mild white fish filets, or robustness to pork chops. Take advantage of the late season glut of sweet bell peppers and add this quick, simple pepper sauté to your dinner plans. Throw in a few spicy chile peppers to liven it up even further!
Low Carb Dinner for Fall
We had the luxury of an extra long growing season in Minnesota this year, and I was able to harvest a boatload of different sweet and hot peppers, along with a bountiful harvest of heirloom squash.
It is always easiest to design a dinner around what is in your fridge (or in this case your garden), and the bright orange bell peppers and squash inspired an Italian Fall dinner with peperonata taking center stage.
The Italian Romesco sauce made with tomatoes, peppers and almonds added sweetness and creaminess without any refined sugar or flour. The beta carotene from the orange peppers and butternut squash added nutrition, along with eye-popping color.
However you decide to mix it up, classic or uniquely yours, peperonata can be a stupendous stand alone side dish or used as a sauté topping for proteins or vegetables on a low carb lifestyle.
