Essential Caramelized Onions Ingredients
• To create your flavorful masterpiece, here’s what you’ll need:
For the Cooking
- Extra-virgin olive oil – Adds richness and facilitates cooking; for a different flavor, use ghee or butter.
- Medium yellow onions – The base ingredient providing sweetness and depth; Vidalia or white onions can also be used for a different sweetness.
- Sea salt – Enhances flavor while aiding in the onion’s moisture release; feel free to substitute regular salt if needed.
How to Make Caramelized Onions
- Slice the Onions: Begin by halving and slicing 4 medium yellow onions evenly. As you slice, gently separate the onion layers to ensure even cooking—this step is essential for achieving that silky texture!
- Heat Oil: In a 12-inch cast-iron skillet, warm up 2 tablespoons of extra-virgin olive oil over medium heat. Take a moment to savor the aroma—this is where your caramelization journey begins!
- Sauté Onions: Add the sliced onions to the skillet, sautéing them for about 5 minutes until they soften, stirring frequently to prevent sticking—watch them transform from crunchy to tender!
- Season & Lower Heat: Sprinkle in ½ teaspoon of sea salt and reduce the heat to medium-low. Stir every few minutes, allowing the onions to release their natural sugars for that delicious sweetness.
- Caramelize: Continue to cook the onions for 50 to 80 minutes. Keep an eye on them, adjusting the heat if necessary to avoid burning, until they turn soft, deeply browned, and beautifully caramelized.
- Final Steps: Check for doneness; your onions should be a rich, golden brown, with a tender texture that melts in your mouth—essential for any savory dish!
Optional: For a touch of sophistication, deglaze the pan with a splash of white wine at the end.

Caramelized Onions Recipe FAQs
How do I select the best onions for caramelizing?
Absolutely! The best onions for caramelizing are medium yellow onions, as they balance sweetness and depth beautifully. However, if you prefer a sweeter flavor, Vidalia onions are a fantastic choice. Always look for onions without dark spots or soft areas—fresh onions should feel firm and have a smooth skin.
How should I store leftover caramelized onions?
To store caramelized onions, place them in an airtight container and refrigerate. They’ll last up to 1 week, making them perfect for adding rich flavor to your meals throughout the week. Just be sure they cool down completely before sealing to prevent moisture build-up!

What are some common issues when caramelizing onions, and how can I fix them?
Some common issues include sticking or burning. If you notice the onions sticking to the pan, reduce the heat or add a splash of water. Stir them regularly to distribute the heat evenly. Remember, patience is key; cooking too quickly can lead to burnt onions instead of that rich, brown perfection!
Are caramelized onions suitable for my dietary needs?
