Peperonata (peh-peh-roh-NAH-tah) is a Southern Italian vegetable dish of slow-cooked, or stewed bell peppers with onion and garlic.
I make peperonata every fall when my pepper harvest at HeathGlen Organic Farm peaks, and I use it on everything: pork chops, bunless burgers, ground beef, white fish, even as a bruschetta topping. This version pairs it with roasted butternut squash and optional romesco sauce for a complete slow carb dinner.

What is Peperonata?
Peperonata is a Southern Italian 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 often includes onions and garlic, you do want to keep it simple and let the flavor of the stewed 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 Do You 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 mixed into ground beef and served with a side of butternut squash topped with Italian romesco sauce. A perfect slow carb Fall dinner!
I have also enjoyed the robust flavor of this stewed pepper blend simmered with pork chops 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. 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!
What is Romesco Sauce
We sometimes have the luxury of an extra-long growing season in Minnesota, and when that happens I can 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 this 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.
