How to Make Caramelized Onions
Step 1: Choose and Slice Your Onions
Start with fresh yellow or sweet onions, peeled and sliced thinly into even strips to ensure uniform cooking and caramelization.
Step 2: Heat Your Pan with Fat
Place a large skillet over medium heat and add butter or olive oil until shimmering but not smoking.
Step 3: Add Onions and Salt
Toss in the sliced onions and a pinch of salt to help release moisture, then stir to coat thoroughly with the fat.
Step 4: Cook Low and Slow
Reduce heat to low or medium-low and cook the onions, stirring occasionally, for about 30 to 45 minutes until they turn golden brown and develop a sweet aroma.
Step 5: Optional Extras
About halfway through, sprinkle a tiny bit of sugar if desired, or add balsamic vinegar for richness just before finishing.
Step 6: Finish and Store
Once deeply browned and soft, remove from heat and let cool slightly before using or storing for later dishes.
Pro Tips for Making Caramelized Onions
- Patience Pays Off: Cooking low and slow prevents burning and allows maximum flavor development.
- Use the Right Pan: A wide, heavy-bottomed skillet promotes even browning.
- Stir Occasionally: Avoid constant stirring, but don’t let them stick to the pan and burn.
- Adjust Heat as Needed: Lower the temperature if onions brown too quickly or unevenly.
- Don’t Skip the Salt: It helps draw out moisture and intensifies the onions’ natural sweetness.

FAQs
How long does it take to caramelize onions?
It typically takes between 30 to 45 minutes on low heat to achieve perfect caramelization, allowing natural sugars to develop fully.
