French Onion Dip

French Onion Dip is one of my favorite foods on the planet. I’m talking the Lipton soup packet, mixed with an entire tub of sour cream, with heavily salted potato chips, ruining my dinner at family parties, etc. This homemade version completely tops the boxed stuff.

Low-and-slow caramelized onions are added to a mixture of sour cream and Greek yogurt along with some flavorful dried spices to create a dip almost identical in taste to the Lipton mix with the addition of real onions. From there, you can use any dipping vehicle you want to scoop up that goodness. It’s beyond delicious!

Ingredients needed to make French Onion Dip

The best part of this dip is that we use real onions to achieve the majority of that “french onion” flavor. They get caramelized slowly in butter, salt, and pepper, and add so much depth of flavor to this dip. I prefer to use yellow onions in this recipe, as their flavor enhances so much as they cook. Here’s everything you’ll need to make this dip:

Tools used to make French Onion Dip

French Onion Dip comes together quickly and using minimal kitchen equipment. You’ll need a cutting board, a sharp knife, a cast-iron or non-stick skillet, a large mixing bowl, a silicon scraper/spatula, and measuring cups and spoons. That’s it!

How to make French Onion Dip

The hardest part of making this French Onion Dip is slicing and caramelizing the onions. This takes anywhere from 20-40 minutes, depending on how deeply caramelized you’d like your onions to be. I tend to like mine with a slight bite left to them, so I’ll opt for the 20-25 minute range, but you can let yours go as long as you desire as long as they aren’t burning!

You’ll start by melting butter in a cast-iron or non-stick skillet and thinly slicing your onions. Add the onions to the skillet along with a pinch each of salt and pepper and cook them over low-medium heat, stirring frequently, until golden and very fragrant, at least 20 minutes but up to 40 minutes. While the onions caramelize, you’ll mix together the sour cream, Greek yogurt, dried parsley, dried dill, garlic powder, onion powder, and salt and pepper to taste. Once the onions are cooked, fold them into the dip, reserving about 1/8 cup to garnish on top of the dip. Transfer the dip to a serving bowl, then spoon the reserved onions over top of the dish. Serve with chips, pretzels, and freshly cut vegetables.
