This caramelized onion dip made with Greek yogurt is a simple, flavorful, and lighter take on the classic onion dip. Slow-cooked onions develop deep, sweet flavor while fresh thyme and a touch of mayonnaise round out the richness. The result is creamy, savory, and packed with real onion taste.
A small amount of mayonnaise adds body and silkiness while plain Greek yogurt keeps the dip tangy and lighter than a traditional sour cream base. The contrast of the sweet caramelized onions, bright vinegar, and aromatic thyme makes this dip irresistible.
For other easy crowd-pleasing dips, try baked ricotta or a spinach bacon bread bowl — both pair well with crackers and vegetables.

You’ll Love Caramelized Onion Dip with Greek Yogurt
This dip hits all the marks: creamy without heaviness, rich in onion flavor, and made from simple, wholesome ingredients. The caramelized onions provide depth that store-bought mixes can’t match, while Greek yogurt brings a pleasant tang and added protein.
Whether you’re hosting a party, watching the game, or enjoying a quiet night in, this dip disappears fast. It’s easy to make ahead and even tastes better after a day in the fridge when the flavors meld.
Ingredients You’ll Need
- Yellow onions — large, thinly sliced for the best flavor and caramelization.
- Olive oil — to sauté and help the onions caramelize evenly.
- Fresh thyme — chopped; dried thyme can be substituted if needed.
- Plain Greek yogurt — 2% is recommended for creaminess; nonfat works in a pinch.
- Mayonnaise — a little adds richness; olive oil or light mayo keeps it lighter.
- Seasonings — garlic powder, onion powder, kosher salt, and black pepper.
- Vinegar or lemon juice — a teaspoon brightens and balances the sweet onions.
How to Make Caramelized Onion Greek Yogurt Dip
Caramelizing the onions is the key step and requires patience. Plan for about 40 minutes to develop the best color and sweetness.
Slice onions into thin strips. Heat the olive oil in a large skillet or Dutch oven over medium heat. Add the onions, fresh thyme, and kosher salt, then reduce the heat to medium-low. Cook slowly, stirring occasionally so the onions brown evenly without burning.
The onions are ready when they’re soft, deep golden brown, and sweet. Remove from heat and let them cool slightly.
In a bowl, whisk together Greek yogurt, mayonnaise, vinegar, garlic powder, onion powder, salt, and pepper until smooth. Fold in the cooled caramelized onions. Cover and refrigerate at least one hour to allow flavors to meld, or up to two days.
Tips for the Best Onion Dip
- Cook the onions low and slow to extract natural sweetness and avoid burning.
- Fresh thyme enhances flavor; substitute a teaspoon of dried thyme if necessary.
- Chill the dip for at least an hour to let the flavors harmonize.
- Taste after chilling and adjust salt and pepper. Garnish with chopped chives for color and freshness.
How to Serve Caramelized Onion Dip
This dip pairs with many dippers. Popular choices include:
- Crackers or toasted crostini
- Potato chips or kettle chips
- Fresh vegetables like carrots, celery, cucumber, and bell pepper
Make-Ahead and Storage Tips
This onion dip is an excellent make-ahead appetizer. Prepare up to two days before serving and keep covered in the refrigerator — the flavor improves as it rests. Store leftovers in an airtight container in the fridge for up to one week and give the dip a quick stir before serving.
