French Onion Dip

I will admit that I have made onion dip from a packet in the past. I’ve also purchased French Onion Dip from a tub that ultimately ends up in the trash because it’s too firm for a chip to survive being dipped into it.

Aside from the homemade version having a super creamy consistency, you also just can’t beat the depth of flavor.

Serve this with a vegetable platter, chips, crackers, and crusty bread. You can even make this a few days ahead of time!

Ingredients

  • Sour Cream– You can also use mayo or a combination of both. The super smooth consistency is perfect for serving with chips.
  • Cream Cheese– Let it sit out and soften while you caramelize the onions so that it’s easy to combine with the other ingredients.
  • Onions– Any kind of onions will work, I usually use yellow onions.
  • Olive Oil & Butter– Perfect for caramelizing onions.
  • Soy Sauce– My Secret ingredient in this dip. I noticed that the package of onion dip mix includes soy sauce extract. It enhances the other flavors in this recipe and adds umami. 
  • Garlic Salt, Onion Powder, Thyme, Pepper– The perfect blend of seasonings and flavors. The thyme adds a nice sophisticated flavor that really puts the “French” in this onion dip. 

How to Make It

See recipe card below this post for ingredient quantities and full instructions.

Heat diced onions in melted butter and olive oil over medium heat for 5 minutes.
