Instructions

  1. Caramelize the onions: Melt the butter in a large skillet over medium-high heat. Add the sliced onions and stir occasionally until they start to brown. Reduce the heat to medium-low and continue cooking, stirring occasionally, for 20-25 minutes until the onions are golden brown and jammy. This step takes patience, but trust me it’s worth it. Let the onions cool for about 5 minutes before using them in the dip.

  2. Blend the dip base: In a food processor, combine the cream cheese, sour cream, mayonnaise, salt, and black pepper. Blend until smooth and creamy.

  3. Incorporate the onions: Add the cooled caramelized onions to the processor and pulse just a couple of times to mix them in. You want some texture, so don’t over-blend!

  4. Garnish and serve: Spoon the dip into a bowl, sprinkle with fresh chives, and serve with your favorite chips, crackers, or even fresh veggies.

Tips & Tricks for the Best Caramelized Onion Dip

  • Low and slow is the key! The secret to perfectly caramelized onions is patience. If you rush the process with high heat, you’ll end up with burned onions instead of that beautiful golden sweetness.

  • Let it sit for a bit. The flavors meld together beautifully if you let the dip rest in the fridge for at least an hour before serving. If you can wait that long, it’s totally worth it!

  • Use full-fat ingredients. While you can swap in lower-fat versions, full-fat sour cream and mayonnaise give the dip the best rich and creamy texture.

  • Make it ahead of time. This dip keeps well in the fridge for up to three days, making it a perfect make-ahead party option.

Delicious Variations to Try

Want to switch things up a bit? Here are some fun ways to customize this dip:

  • Bacon Lovers’ Dream: Stir in crispy crumbled bacon for a smoky, savory twist.

  • Cheesy Upgrade: Mix in ½ cup of shredded sharp cheddar or gruyère for extra depth.

  • Spicy Kick: Add a pinch of cayenne or a few dashes of hot sauce for some heat.

  • Herbaceous Touch: Swap out chives for fresh thyme or rosemary for a different layer of flavor.

  • Vegan Option: Use dairy-free substitutes like cashew-based sour cream and plant-based mayo. Caramelized onions are already naturally vegan, so you’ll still get that incredible flavor!

Frequently Asked Questions

Can I caramelize onions ahead of time?
Absolutely! Caramelized onions can be made up to three days in advance and stored in an airtight container in the fridge. Just bring them to room temperature before mixing them into the dip.

Can I use red onions instead of yellow?
Yes, but keep in mind that red onions have a slightly sharper taste. They’ll still caramelize beautifully, but the flavor will be a little different—still delicious, though!

What should I serve with this dip?
Classic potato chips are my go-to, but pita chips, crackers, fresh veggies, or even toasted baguette slices work perfectly, too.

Can I freeze caramelized onion dip?
I wouldn’t recommend it. The dairy components don’t freeze well and can separate once thawed, changing the texture of the dip.

Caramelized onion dip is one of those recipes that proves simple ingredients can create something spectacular. It’s rich, creamy, packed with flavor, and guaranteed to disappear fast at any gathering. Plus, making it yourself means no preservatives or weird ingredients just pure, homemade goodness. So grab those onions, fire up your skillet, and get ready for a dip so delicious, you’ll wonder why you ever settled for store-bought.
