Ingredients You’ll Need
- Yellow onions – large, thinly sliced for best flavor.
- Olive oil – a small amount to help the onions caramelize.
- Fresh thyme – adds a subtle herbal note; dried thyme works in a pinch.
- Plain Greek yogurt – 2% Greek yogurt provides the best texture and flavor.
- Mayonnaise – a bit of mayo adds richness; olive-oil based or light mayo keeps it lighter.
- Seasonings – garlic powder, onion powder, kosher salt, and black pepper.
- Vinegar or lemon juice – a small splash to brighten the finished dip.
How to Make Caramelized Onion Greek Yogurt Dip
The key step is caramelizing the onions slowly; this requires patience but yields sweet, deeply flavored onions. Plan on about 40 minutes for the best results.
Begin by halving and thinly slicing the onions into long strips. Heat olive oil in a large skillet or Dutch oven over medium heat. Add the sliced onions along with chopped fresh thyme and a pinch of kosher salt. Reduce the heat to medium-low and cook slowly, stirring occasionally, until the onions are soft and golden brown—about 40 minutes. Remove from heat and allow the onions to cool slightly.
In a medium bowl, whisk together the Greek yogurt, mayonnaise, vinegar, garlic powder, onion powder, salt, and pepper until smooth. Fold in the cooled caramelized onions. Cover and refrigerate for at least an hour to let the flavors meld. Taste and adjust seasoning before serving.
Tips for the Best Onion Dip
- Cook low and slow. Rushing the onions will prevent the deep, sweet caramelization you want.
- Use fresh thyme when possible. It complements the onion’s sweetness. If using dried thyme, reduce the amount slightly.
- Chill before serving. Refrigerating the dip for at least an hour helps flavors meld and improves texture.
- Adjust seasoning after chilling. Flavors can mellow in the fridge, so taste and add extra salt, pepper, or a splash of vinegar if needed. Garnish with fresh chives for color and flavor.
How to Serve Caramelized Onion Dip
This creamy dip pairs with many dippers, including:
- Crackers or crostini
- Potato chips or kettle chips
- Fresh vegetables such as carrots, celery, cucumber, and bell pepper
Make-Ahead and Storage Tips
This dip is an excellent make-ahead appetizer. Prepare it up to two days in advance and keep it covered in the refrigerator—the flavors often improve after resting. Store leftovers in an airtight container for up to one week; stir briefly before serving.

- 1 ½ cups plain Greek yogurt (I recommend 2% Greek yogurt)
- ½ cup mayonnaise (use olive oil mayo or light mayo)
- 1 teaspoon vinegar
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt & pepper to taste
Instructions

Notes
Great served with chips, crackers, or fresh vegetables. This dip can be made a day or two ahead — chilling improves the flavor.
- Sliced onion: cutting lengthwise into long strips yields noticeable ribbons of onion; chop smaller for finer pieces in the dip.
- Thyme: fresh is preferred, but 1 teaspoon dried thyme can be substituted.
- Mayo: olive-oil based or reduced-fat mayonnaise works well to keep the dip lighter.
- Yogurt: 2% or 5% Greek yogurt gives the best texture; nonfat can be used if preferred.
