Tips & Variations
- Low and Slow Wins the Onion Game
Resist the urge to turn up the heat—true caramelization takes 40+ minutes. Fast-tracking will leave you with burnt or bitter onions. - Deglaze if Needed
If onions begin to stick or dry out, add a splash of water to release the flavorful brown bits. - Substitution Options:
- Use sweet onions (like Vidalia) for an even gentler flavor.
- Red onions work too but bring a sharper taste and deeper hue.
- Swap butter with ghee or olive oil for a dairy-free twist.
- Fresh herbs like parsley or thyme add color and brightness.
- Make It a Meal:
Serve over toast, rice, or with roasted potatoes for a heartier dish. A handful of shredded cheese melts in beautifully too.

FAQs
What kind of onions are best for caramelizing?
Yellow onions are the top pick due to their balanced sweetness and mild bite. Sweet onions like Vidalia work great too, but caramelize faster.
Can I make the onions ahead of time?
Absolutely. Store caramelized onions in the fridge for up to a week. They actually taste better the next day and reheat beautifully in a pan.
Do I have to use butter?
Nope! You can use more olive oil or try ghee, coconut oil, or even a plant-based butter substitute for a dairy-free version.
What size eggs should I use?
Large eggs are standard, but medium or extra-large will work too. Just keep an eye on cooking time.
