Greek yogurt isn't the only thing doing the heavy lifting on this site's dip lineup. If you like a tangy, make-ahead dip, this white bean dip leans on the same "simple ingredients, big flavor" approach; muhammara shows how far a slow-cooked base can carry a dip when you let it do the work; and this spinach and crab dip rounds out the range of what a good dip on this site can look like. All three prove a dip doesn't need a long ingredient list, just the right technique.

This dip earns its spot on any spread, but it's especially good next to something rich. It is similar to the French Onion Chicken and the French Onion Pasta recipes. There is nothing better than caramelized onions to make a dish perfect!
Key Ingredients
You will need the following ingredients to make this French onion dip:
- Yellow Onions - Onions are the whole recipe here, not a garnish on top of a yogurt base. In testing, low and slow was non-negotiable: high heat browns the outside of the onions while the inside stays raw, so the full 45 to 50 minutes matters. This is what separates a real caramelized onion dip from one built on dried onion flakes, and it's the reason this recipe fits the Mediterranean approach of letting a slow-cooked ingredient carry the dish.
- Full-Fat Greek Yogurt - Full-fat Greek yogurt gives this dip a tangier, lighter base than sour cream without sacrificing richness. It also holds up better once the onions are folded in. Nonfat yogurt tends to thin out and lose that creamy texture, so full-fat is the version worth using here.
- Dry White Wine - A splash of dry white wine deglazes the pan after the onions caramelize, lifting the browned bits stuck to the bottom, the fond, and folding all that flavor back into the onions instead of leaving it behind. This is the step most French onion dip recipes skip entirely, and it's what gives this version real depth instead of relying on Worcestershire. I also tested this with dry sherry and it was equally delicious. If you want a non-alcoholic version, replace the wine with a splash of low-sodium chicken broth.
- Fresh Garlic - Fresh garlic cloves, added toward the end of caramelizing, keep their bite without turning bitter. Garlic powder is also whisked into the yogurt base for a rounder, more consistent garlic flavor throughout the dip rather than just in the onions. If you prefer a more mellow garlic flavor, use garlic confit with the onions.

How To Make Greek Yogurt French Onion Dip: Step-By-Step
Here are some quick visual instructions. Remember that full instructions with the exact ingredients are in the printable recipe card:
Step 1: In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and a pinch of salt.
Step 2: Cook the onions, stirring occasionally, for 45 to 50 minutes, until they're evenly caramelized and a deep golden brown. Add the minced garlic and stir for another 3 to 5 minutes, until fragrant.
Step 3: Pour in the white wine. Use a wooden spoon to scrape up the browned bits from the bottom of the pan. Stir in the Worcestershire sauce and fresh thyme, and cook for 2 more minutes, until the liquid has mostly evaporated. Remove the onion mixture from the pan and let it cool completely to room temperature.
Step 4: In a medium bowl, whisk together the Greek yogurt, garlic powder, and black pepper. Fold in the onion mixture. Taste before adding salt. Cover and refrigerate for at least 2 hours before serving.
Gwen's Pro Tip
Cool the onions completely, fridge-cold if you have time, before folding them into the yogurt. Warm onions are the single most common reason this style of dip turns thin instead of creamy.

Equipment
- 1 small bowl
Ingredients
- 2 large yellow onions halved and thinly sliced
- 2 tablespoons unsalted butter
- 1 tablespoon extra virgin olive oil
- 2 garlic cloves minced
- 2 tabelspoons dry white wine or dry sherry
- 1 teaspoon Worcestershire sauce
- 1 teaspoon fresh thyme leaves
- ½ teaspoon garlic powder
- 2 cups full-fat Greek yogurt
- heavy cream optional
- Kosher salt and black pepper to taste
Instructions
- In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and a pinch of salt.
- Cook the onions, stirring occasionally, for 45 to 50 minutes, until they're evenly caramelized and deep golden brown. If they start to burn or darken too quickly, lower the heat and add a teaspoon of water to the pan.
- Add the minced garlic and stir for another 3 to 5 minutes, until fragrant.
- Pour in the dry white wine. Use a wooden spoon to scrape up the browned bits from the bottom of the pan.
- Stir in the Worcestershire sauce and fresh thyme, and cook for 2 more minutes, until the liquid has mostly evaporated.
- Remove the onion mixture from the pan and let it cool completely to room temperature. Do not add warm onions to the yogurt. Warm onions will thin the dip and make it runny instead of creamy.
- In a medium bowl, whisk together the Greek yogurt, garlic powder, and black pepper. Fold in the cooled onion mixture. Taste before adding salt. The Worcestershire already brings a good amount of seasoning.
- Cover and refrigerate for at least 2 hours before serving. This gives the onions time to settle into the yogurt and lets the flavors come together.
- Before serving, top with a spoonful of reserved caramelized onion and a scattering of fresh thyme.
