French Onion Dip Ingredients

What we are looking at is a list of 10 ingredients out of which 7-8 are pantry staples. Most likely there is one ingredient that you might not have handy, but I will tell you a substitute for that as well.

  • Onion – Yellow, white, or brown onion will work. Dice onion to cook and caramelize evenly.
  • Garlic– Garlic enhances and compliments the flavor of onion.
  • Butter and olive oil– Obviously butter is flavor. But to cut down the richness, olive oil works best.
  • Mayo
  • Sour cream
  • Thyme, chive, salt and pepper
  • Worcestershire sauce- If you don’t have Worcestershire sauce, you don’t need to do a grocery run for only this one ingredient. You can either skip it or substitute it with soy sauce.

How to make

The key to making French onion dip is to caramelize the onion perfectly. So gather all your patience and keep aside 30 minutes of your time(you need to stand by the stove while making this) for this step. It might seem like a daunting task, but there is no shortcut to this. If hurried, Onions will burn in no time and taste bitter. When a large pinch of salt is added to the onion, it sweats onion faster.

Start with medium-high heat and saute the onions. When the onions have softened and look translucent, reduce the heat. From there on cook onion on low heat, stirring frequently. Add a splash of water a couple of times, to prevent the onions from burning. Onion when caramelized perfectly has a sweet and savoury taste.

Cool down the onion. Meanwhile, mix sour cream, mayo, chives, parsley(if using), salt and pepper. Add cooled down onion. Check seasoning and adjust as per preference.

How long Homemade French Onion Dip can be stored?

Once ready, I prefer to refrigerate for a couple of hours before serving. It gives time for the flavors to blend. You can store the dip for up to 3 days and it will only get better. The dip might thicken up when chilled, so add a little water or milk to adjust the consistency.

Because of the dairy ingredients, this dip is not ideal for freezing as it might split.

To make it ahead for a party or large gathering, you can make it a day ahead and rest in the refrigerator.

What to serve French onion dip with?

The best pairing I can think of is French onion dip with ridged potato chips. That’s the classic combination. Apart from that you can serve pita chips, bagel chips, or even veggie sticks.
