Borettane onions are a type of onion that is popular in Italy. They are small, round onions with light yellow skin and a sweet flavor. They are often used in salads, pickled, as a side dish, appetizers, or garnished on other meals.
We are fans of caramelizing onions for risottos and putting them on top of pizza or Spanish omelettes.
This spiced onion recipe was inspired by the roasted Spanish escalivada recipe on this site, and pairs well with rosemary focaccia bread, Pagnotta (easy Italian bread loaf), inside arepa sandwiches, or on top of traditional hummus or guacamole for an unexpected twist.

See the recipe card for quantities.
🔪 Instructions
So, this is how to make spiced onions in four simple steps.

Soak the onions in cold water to make it easier to peel them.

On low heat, infuse the olive oil with the rosemary sprig and pepperoncini for 2-3 minutes.

Fry the onions in a pan with a little olive oil and rosemary and pepperoncini until lightly golden

Add one cup of water and put the lid on. Let them cook for 15-20 minutes.
💡Top tip
Let the onions cook until almost all the water is consumed and the onions are perfectly soft but haven't lost their shape.

🍶 Substitutions
- Onions - instead of borettane onions, you can use any small-sized onions, like pearl onions. In that case, add one tablespoon of sugar; since these Italian onions are more sugary than regular ones, you will need extra sugar to caramelize the onions.
- Regular onions - you can apply the same technique to other types of onions, such as yellow, white, or red onions. Simple use of thick onion slices or coarsely chopped onions.
- Pepperoncini - use red chili flakes or any other fresh or dried chili.
- Rosemary - use fresh thyme sprigs or sage.
- Extra-virgin olive oil - any other oil will work. You can use regular vegetable oil, just about using oil with a distinctive flavor like coconut oil.
📖 Variations
- Middle eastern - instead of rosemary and pepperoncini, add ½ teaspoon of sumac, Lebanese seven spices, lemon peel, and/or paprika. Then add them to vegan kebabs, and serve with tabbouleh salad.
- Indian spiced onions - to give a different flavor profile to these spicy onions, you could use Indian spices, such as cumin powder, cumin seeds, chaat masala, garam masala, lemon juice, chilli powder, fenugreek leaves, or cayenne pepper. Simply infuse the oil with the spices before adding the sliced onions to the saucepan.
The Indian spiced onions are the perfect accompaniment for mango chutney and cucumber mint sauce, as they usually serve them in Indian restaurants for the total feast.
Serve sauteed onions recipe next to basmati rice and your favorite Indian eggplant curry, red lentil dal, or cauliflower curry.
Another great pairing is a mushroom tikka masala curry.
🥢 How to serve
These small Italian onions (cipolline) are traditionally served as a side dish for meat or as an appetizer with cured meat and cheeses.
We suggest serving them vegan options like focaccia bread as part of a vegan charcuterie board, including red pepper hummus, Spanish tapas like sautéed chickpeas and spinach, muhammara toasted walnuts dip, pumpkin hummus, roasted butternut squash, Spanish vegetables, vegan ricotta cheese, and crackers.
