Don’t you hate it when others mock your goals? For instance, when you’re trying to go to Shredsville and everyone at the party wants to ask whether every item on the table is “on your diet” or not. Well, this lower calorie onion dip is the perfect way to stick it to ’em.
They’ll never know you’ve brought a low fat dip, and you can cherish every bite they take as you know it’s definitely “on your diet.” Thanks to the caramelized onions and one special ingredient, this dip is perfectly sweet and salty, creamy, and umami. And every 1/3 cup serving has just 75 calories and 3 grams of fat!
Greek Yogurt Onion Dip Recipe Walkthrough
I’ll run you through the recipe from start to finish below and touch on ingredient modifications along the way. You can find a printable recipe card at the bottom of the post as well.
Step 1: Dice Three Yellow Onions
You can use white onions if that’s all you have on hand, but I find yellow onions work best for caramelization.
If you don’t have a food scale to weigh the onions after dicing (the recipe calls for 900 grams), be sure you’re using large onions. While it’s difficult to mess this onion dip up, a different amount will affect flavor, cook time, and consistency of the finished product.
Step 2: Heat Olive Oil in a Pan over Medium Heat and Add the Diced Onion, Salt, and a Sugar Substitute
In case you’re wondering, it’s possible to caramelize onions without oil. Especially if you’re using a nonstick pan like I used for this recipe. That said, the olive oil provides a ton of flavor and only adds about 8-10 calories per serving.
Side note: If you’re using stainless steel or cast iron, I’d definitely recommend using the oil.
The salt and sugar substitute (or sugar) are to speed up release of moisture from the onions and give the caramelization process a little boost. You can skip this step but if you do, you’ll want to add a bit of salt to the dip at the end (to taste).
Step 3: Cover and Cook for Five Minutes
Once the onions begin to soften, give them a good stir and cover to continue cooking. If you’re using stainless steel, cast iron, or going without oil and notice any sticking or browning on the bottom of the pan, you can add the Worcestershire in small amounts to deglaze the pan along the way.

Step 4: Repeat in Five-Minute Intervals until the Onions Begin to Brown
Continue this process until you see very little white remaining in the onions.
Step 5: After 15-20 Minutes, Add Worcestershire Sauce and Cook until No Liquid Remains
The Worcestershire provides that savory umami flavor we all love. If you’re not a fan, though, you can use something like white wine vinegar or another type of vinegar. You could also skip this step entirely.
Step 6: Mix Fat Free Greek Yogurt, Light Mayo, White Pepper, Parsley Flakes, and Garlic Powder in a Large Bowl
Considering this is a Greek yogurt onion dip, the Greek yogurt is a pretty mandatory ingredient. If you need a dairy free onion dip, however, I’m sure a plant-based yogurt would do the trick. For another dairy alternative, I’ve had great success with cottage cheese for things like queso con carne and jalapeño ranch dip.
And for the light mayo, I bet you could use fat free or 1/3 fat cream cheese in its place. And they make plant-based versions of both mayo and cream cheese products. What a time to be alive!
As for the additional seasoning, you can get creative here. Garlic powder is probably the most important addition, in my opinion. The white pepper and parsley, on the other hand, could be swapped for all kinds of things. Black pepper is always a good idea, and other herbs will provide a hint of freshness to the dip. Have fun with it.
Step 7: Add the Cooked Onion to the Greek Yogurt Mixture
Bring it all together, and you’re done! While the onion dip itself is lower calorie, you’ll want plenty of options to serve it with. To appease your haters, the crinkly potato chips are king for serving with onion dip. So get some of those for sure but sneak in some other dipping apparatuses:
- pita chips and other thin crackers (be careful here as lots can be just as bad as potato chips)
- baked or air fried potato chips
- fresh veggies like carrots, zucchini, pepper slices, or celery
- grilled bread or crostini like I serve with my whipped feta and roasted tomatoes
