What is peperonata agrodolce?

Peperonata sauce, or peperonata agrodolce, is a rustic Italian sauce made with stewed tomatoes, peppers, onions, garlic and vinegar. Embrace the rustic sauce by using large or varying sized knife cuts for great texture.

Agrodolce is a sweet and sour Italian condiment. The stewed tomatoes and peppers, along with the vinegar create a delicious peperonata agrodolce that’s tasty on so many dishes like pasta, eggs, toast, with chicken or sausages, or smeared on a sandwich or wrap.

Is peperonata sauce healthy?

Absolutely! One of my favorite ways to boost nutrient density is to add a sauce that’s made of vegetables or herbs.

This peperonata recipe is no exception and adds a lot of nutrients to any meal.

It’s made of pure, nourishing, whole food ingredients!

Tomatoes and peppers

Tomatoes and peppers, alongside white potatoes and eggplant are part of a species of vegetables in the nightshade family.

Nightshades can be irritating to some people especially those with joint or autoimmune conditions. The sensitivity can vary from person to person, and doesn’t apply to everyone with those conditions, but if you don’t tolerate nightshades well then this recipe may not be for you.

However, if you’re not sensitive to nightshades vegetables then you can enjoy all the nutritious properties they carry like vitamins A, C, and B, antioxidants like lycopene that reduce inflammation and fiber. Sweet bell peppers have twice the amount of vitamin C of an orange.

In fact, if you struggle with a lot of bloating, IBS or SIBO then tomatoes and peppers can help decrease those symptoms as they’re considered to be low fodmap – a category of foods with low fermentable fibers which can contribute to gas and bloating.

Alliums for gut health

Onion, leek and garlic are part of the allium family of vegetables.

These vegetables are know for their sulfur, prebiotic and antiviral properties, which are incredibly beneficial for gut health and detoxification.

BUT if you experience a lot of gas ad bloating, these fibers may be adding to those symptoms. Avoiding these foods isn’t a solution because it’s not addressing the root cause, but if you feel relief by temporarily avoiding these foods, schedule a 30-minute nutrition strategy session to discover the root cause.

Different variations of peperonata sauce:

  • Use any tomatoes you have accessible to you. You can even used jarred tomatoes like Jovial if you’d like.
  • Use any vinegar you have, although I recommend red wine vinegar
  • Use any peppers! Use sweet peppers for the majority like a red bell peppers, green bell peppers, some gypsy peppers, anaheim, banana, cherry, or heirloom peppers, or a mix of a few different kinds. Jimmy nardello peppers are my favorite if you can find them! But you really can’t go wrong with whatever you have.
  • Add spicy peppers and more red pepper flakes if you like a kick! Try a jalapeno, serrano, fresno, habanero.
  • If alliums (onions and garlic) make you feel bloated, as mentioned above, feel free to leave them out. The agrodolce will be just as delicious especially with the vinegar. OR you can try using leeks and garlic olive oil which are lower in the fodmap’s that can be difficult for some people with IBS to tolerate.
  • Add other vegetables to the sauce like eggplant or zucchini for a heartier stew.
  • In the last 5 minutes of cooking, add a handful of fresh herbs like basil, parsley or oregano for some herby freshness.
