Ingredients You’ll Need
This recipe keeps things delightfully simple, but every ingredient is essential, each one bringing its own magic to the dish. From the natural sweetness of onions to the deep, complex notes of balsamic, these basics come together for truly unforgettable Crockpot Balsamic Glazed Caramelized Onions.
- Yellow Onions: Four large onions, thinly sliced, are the heart of this recipe, providing sweetness and a silky texture as they cook down.
- Olive Oil: Two tablespoons of olive oil add richness and help the onions begin softening and caramelizing right from the start.
- Balsamic Vinegar: A quarter cup brings that signature tangy-sweet glaze and deep brown color to the finished onions.
- Brown Sugar: Two tablespoons balance the vinegar and amplify the onions’ natural sugars for irresistible caramel notes.
- Salt: Just half a teaspoon rounds out the flavors and draws moisture from the onions as they cook.
- Black Pepper: A quarter teaspoon adds subtle warmth and a peppery kick.
- Water or Low-Sodium Broth: A splash (a quarter cup) keeps everything moist and prevents sticking during the long, slow cook.
How to Make Crockpot Balsamic Glazed Caramelized Onions
Step 1: Sauté the Onions
Start by heating your olive oil in a skillet over medium heat. Add the sliced onions and sauté for about five minutes, just until they’re beginning to soften and pick up a hint of color. This quick step jumpstarts the caramelization, ensuring your Crockpot Balsamic Glazed Caramelized Onions develop the richest flavor and texture possible.
Step 2: Transfer to the Crockpot
Once the onions are slightly softened, transfer them to your crockpot. Make sure to scrape every bit of onion and olive oil into the pot—those early flavors are going to pay off later!
Step 3: Add the Magic
Drizzle the balsamic vinegar over the onions, sprinkle on the brown sugar, salt, and pepper, then pour in the water or broth. Give everything a gentle stir to combine. This mixture is where the transformation begins—the glaze will infuse the onions with bold, tangy-sweet complexity as they cook.
Step 4: Slow Cook to Perfection
Cover the crockpot with its lid and set it to low. Let the onions cook for 6 to 8 hours, stirring once or twice if you can. By the end, your kitchen will smell incredible, and the onions will have turned deeply golden, tender, and sticky with glaze—the unmistakable signature of Crockpot Balsamic Glazed Caramelized Onions.
Step 5: Taste and Finish
Once the onions are beautifully caramelized, give them a taste and adjust the seasoning if needed. If you want extra depth, now’s the time to add a splash of red wine or tweak the salt and pepper. Serve them warm, and get ready for them to steal the show!

Reheating
To bring your Crockpot Balsamic Glazed Caramelized Onions back to life, simply warm them gently in a skillet over low heat, stirring occasionally.
