Instructions:
1. Prepare the onions:
-
Peel and slice the onions thinly into half-rings or rings. The thinner the slices, the faster and more evenly they’ll caramelize.
2. Cook the onions:
-
Heat the olive oil and butter (if using) in a large skillet over medium heat. Once the butter has melted and the oil is hot, add the sliced onions.
-
Stir the onions to coat them in the oil and butter. Sprinkle them with a pinch of salt to help draw out moisture.
3. Caramelize the onions:
-
Cook the onions over medium-low heat, stirring occasionally to ensure they cook evenly. The key here is patience—the caramelization process takes time (about 30-40 minutes).
-
If the onions start to stick to the pan, you can add a splash of water or a bit more oil. You want the onions to soften and slowly turn golden brown, releasing their natural sugars.
-
After about 15 minutes, sprinkle in the sugar to enhance the caramelization process, but this is optional if you want a more naturally sweet flavor.
4. Add balsamic vinegar:
-
When the onions have turned a deep golden brown and become very soft, add balsamic vinegar to the pan. This will add a little acidity to balance the sweetness of the caramelized onions.
-
Stir well to incorporate the vinegar and let it cook for a couple of minutes, allowing it to reduce slightly and coat the onions.
-
Taste and adjust with more salt and pepper as needed. You can also add a sprig or two of fresh thyme at this point for extra flavor.
5. Serve:
-
Once the onions are beautifully caramelized, remove them from the heat. Serve immediately as a side dish or use them as a topping for various dishes.
Tips:
-
Use a wide pan: A large skillet or sauté pan will help the onions spread out, allowing them to caramelize evenly.
-
Adjust sweetness: If you prefer your onions sweeter, you can add more sugar or even a touch of honey during the caramelization process.
-
Flavor variations: Feel free to experiment with adding a bit of red wine, herbs (like rosemary or bay leaves), or even garlic to the onions as they cook.
-
Storage: Leftover caramelized onions can be stored in an airtight container in the fridge for up to 3-4 days. You can reheat them gently in a pan or microwave.
Pairing Suggestions:
-
Meats: These onions are fantastic paired with grilled meats, roasted pork, or steaks.
-
Cheese: They also work wonderfully with soft cheeses like goat cheese, brie, or even blue cheese.
-
Burgers and sandwiches: Add caramelized onions to your favorite burgers or sandwiches for an extra layer of flavor.
