Caramelized Onions

Are you an onion hater? If so, these velvety-smooth Caramelized Onions might just change your mind! I love onions in every form, but when cooked low and slow until golden brown and sweet, they become the side dish you never knew you needed. Use them to top a burger, add them to dips and sauces, or mix them into your favorite pasta dish! They’re a seriously budget-friendly way to add extra flavor to any meal. Plus, did you know you can get rid of onion breath by eating fresh parsley? You have no excuse now! Let’s dig in.

If you watch Budget Bytes’ reels on social media, you probably already know onions are my favorite ingredient of all time. My stepdaughter, Bijou, knows my commitment to this vegetable from our game “Anything or Onions,” where she puts an undeniably delicious food (say, brownies) up against onions and the I have to choose which one I’d rather eat for the rest of my life. Spoiler alert: I always choose onions.

Why? Onions are sweet, spicy, and savory, wrapped in one cute little bulb! They can be crunchy (like our pickled red onions) or soft and buttery, like in this recipe you’re about to make. The Vidalia Onion is also the official state vegetable of my birthplace, the great state of Georgia!

What Are Caramelized Onions?

Caramelized onions are made by slowly cooking onions over a low heat until their natural sugars caramelize. I don’t add any extra sugar to this recipe, just a little oil, butter, and salt. As they cook, the water in the onions evaporates, and the pungent, sharp taste turns into a sweet, jammy, and savory treat. This process does take time (about 50 minutes) but requires very little effort. Make a big batch, and store them in your fridge to add meals throughout the week!

Ingredients

Here’s what you’ll need to make this caramelized onions recipe:

Onions: I used 3 medium yellow onions, which I sliced into even strips. White or red onions will also work well!
Olive Oil: Stops the onions from sticking to the pan and helps them caramelize evenly.
Butter: Adds a rich, buttery flavor to the onions. The milk solids in the butter will also brown as the onions cook, making them even more flavorful. Use unsalted butter as we add salt separately.
Salt: Draws out moisture from the onions (helping to speed up the caramelization process) and enhances their natural sweetness.

Serving Suggestions

I can’t think of many dishes that wouldn’t benefit from a spoonful of caramelized onions! Some recipes, like French onion soup, even use them as the main ingredient. Here are a few more serving ideas:

If you don’t fancy soup, try making this French onion dip!
Use them to top turkey burgers and hot dogs
Add them to pasta—they’d taste great in this bruschetta pasta recipe!
Top steak, tofu, or grilled mushrooms with a generous serving of these onions
Use in recipes that call for caramelized onions, like our mushroom white pizza, artichoke flatbread, or chickpea spread
Mix them into scrambled eggs or omelets
Add them to hummus breakfast tacos or avocado toast
Use them in place of onion jam on cheese platters

Tips for the Best Caramelized Onions

The exact timings will depend on the thickness of your onion slices and the size of your pan. Don’t be tempted to turn up the heat to speed up the process—this can cause the natural sugars to burn, rather than caramelize! I’ve included photos of my onions after 10, 25, and 40 minutes of cooking in the step-by-step below. Once your onions look like mine in the final photo, they’re done!
Don’t add extra sugar or sweeteners to speed up the caramelization process; this recipe really doesn’t need it. Time and patience will give you the best results!
Salting the onions before cooking will draw out moisture and help them cook down faster.
Deglaze the pan with a splash of liquid (like water, broth, vinegar, or wine) if your onions look dry. You shouldn’t have to do this if you keep the heat low, but it can also add some (optional) extra flavor if desired.
Cut your onions with a sharp knife to avoid that dreaded onion eye burn! You could also try Marsha’s Instagram reel trick for laying a wet paper towel over your cutting board—she says it really works!

Storage Instructions

Keep your onions in an airtight container in the fridge for up to a week, or freeze them for later. They’ll keep for 3-6 months in the freezer. Let them thaw in the fridge before using!
