Best Caramelized Onions
Y’all are going to love today’s recipes! It’s so simple – but you have to have a little patience. Trust me, it’s worth it!
With the weather warming up, I’m thinking about all kinds of grilling recipes – namely burgers! And one of my absolute favorite toppings is this Caramelized Onions recipe! So I’m sharing it with you today!
You’ll only need a handful of ingredients that you probably already have on hand. You’ll also want to use a heavy skillet for this – stainless steel or cast iron are best. For this recipe, you’ll want to skip the non-stick skillet if it’s at all possible.
Let me show you how it’s done …
Caramelized Onions recipe

- butter
- salt
- water
How to make Caramelized Onions
Time needed: 55 minutes.
How to make Caramelized Onions
- Cut onions.
Prepare the onions by removing the skin and the stem and root of the onion. Cut the onion in half from top to bottom. Make angled cuts into the onion along the natural lines that appear on the onions. Separate the slices and set them aside. Continue through all four or more onions.
- Place ingredients in pan and stir.
Add the butter and sliced onions to a large stainless steel pan or cast iron pan over medium heat. Stir so that the onions are coated with the butter and sprinkle the salt evenly over the top.
- Cook.
Lower the heat to medium-low and continue to stir the onions every one to two minutes, allowing them to caramelize on the bottom of the pan in between stirring for 40 to 45 minutes or until caramelized to your liking. If your onions are sticking or if the bottom of the pan starts browning too much, add a splash (no more than 2 tablespoons) to deglaze the pan and add color to your onions.
- Serve.
Use immediately or allow to cool before storing in the fridge.
Recipe Notes
- The key to success here is to cook low and slow – don’t try to rush it!
- If you use salted butter, be sure to consider that when seasoning with any additional salt.
- Do not cover the pan while cooking.
