Tell Us About These Caramelized Onions

We love caramelized onions, but instead of standing by the stovetop for about an hour to caramelize them, try this easy method! Simply slice the onions and bake them on a cookie sheet with three ingredients for about 30 to 40 minutes. They will turn out perfectly every time. Best of all – the oven does all the work, it’s hands-free!

Caramelized onions are a simple dish to serve as a side or have them readily available to top your favorite barbecue dishes, grilled flank steak, hot dogs, burgers, chicken cutlets, and more.

This recipe was given to me by my cousin, Guilianna, while we were in Sicily. In the old days, this dish was a typical peasant dish and was served as a side dish to enjoy with some crusty bread. Today, we love them especially to top almost anything, like grilled chicken, burgers, meats, bratwurst sandwiches, and even on top of pizza.

What are Caramelized Onions?

Caramelized onions are onions that have been slowly cooked down and usually on stove top and over low heat until they become golden brown, and the sugars break down to become sweet and intense in flavor. But this is a NEW method for making caramelized onions, and it’s easier and simpler, the Italian way!

Recipe Tips

• This is a recipe that doesn’t have exact measurements of ingredients. We used only 4 ingredients, and you’ll see why with our descriptions below.
• Keep in mind, onions will most likely make you cry while slicing them. So we suggest you run them under water for a few seconds before slicing. This will help a little, but not totally.
• Also, when slicing, they do not have to be perfect.
• Plus, we used two large onions, but you can use smaller ones and add as many slices as you can fit onto your baking sheet.
• When baking the onions in the oven, there’s no need to turn them over; they will caramelize on the bottom.
• When serving, you will need to use a spatula to pick up and “flip each one” (sliced rings of onion) onto your serving platter for better presentation.
• These caramelized onions can be served warm, cold, or at room temperature.

What You’ll Need to Make these Caramelized Onions

For our recipe, you will need the following four ingredients: 2 large onions, extra virgin olive oil, salt, and sugar. Oh, and you can garnish with any fresh herbs you may have on hand.

How to Make Caramelized Onions in the Oven?

If this is your first time making these caramelized onions, no worries, it’s very easy. First, gather your 4 ingredients. Plus, our full printable recipe is located at the bottom.

1. First, prepare your baking sheet. Drizzle some extra virgin olive oil, and use your hand to spread it over your baking sheet. Then lightly scatter some sugar over the entire surface.

2. Take your onion, peel, and remove its skin. Then place it onto a cutting board, and slice it into 1/4 to 1/2-inches thick (as shown in the photos below). QUICK NOTE: They do not have to be perfect. Plus, you can use a mandolin slicer, if that helps.

3. Place the onion slices onto your prepared baking sheet, side by side. Lightly scatter with salt on top and then drizzle lightly with some olive oil.

4. Bake in the oven at 375°F (180C) for about 30 to 40 minutes until the onions are golden brown around the edges. Remove, use a spatula to flip them over onto a serving platter, garnish with any sprigs of fresh herbs, and serve.

COOK’S TIP! They will have the golden, caramelized color on the bottoms. If you wish to have them darker in color? Then continue to bake them for a few minutes more.
