What Do You Dip in Homemade French Onion Dip?

The flavor each person is looking for is different, but my kids love to dip wavy and rippled chips into this dip. What do you like to dip in French Onion Dip? The light flavor complements the dip wonderfully. They also love dipping their vegetables, crackers, pretzels, and even toasted bread at dinner. House favorite vegetables for this French onion dip include baby tomatoes, cucumbers, broccoli, cucumber, and cauliflower, but I recommend that you use whatever you love.

How Do You Make French Onion Dip from Scratch?

To start your dip, you will need to dice and caramelize your onions. I use three large onions for each batch of French onion dip, which may seem like a lot when you first dice them, but they cook down a lot when you caramelize them. This is the most difficult and time-consuming part of making this delicious dip. To bring out the best flavor in this dip, you will want to caramelize your onions slowly on low for about 30 minutes, stirring them every few minutes.

While your onions are cooking, you can assemble the rest of the dip. Combine the mayo and sour cream and then add your garlic, dried onion, Worcestershire sauce, salt, and pepper. Once this is mixed place a lid or saran wrap on top of the bowl and place it in the refrigerator to wait for the caramelized onions.

When your onions are caramelized, they will need to cool completely before you add them to your dip. I let mine cool for about 20 minutes before mixing them in, so they don’t warm up the sour cream. Once they are cool, you can just fold them into your dip.

You could eat your dip right away but I prefer to let it sit in the refrigerator for at least an hour so the flavors have a chance to blend together and, as my kids say “get happy in the bowl together”. Your dip will last in the refrigerator for up to 5 days.
