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!

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.

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.

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.

The onions were likely still warm when mixed into the yogurt. Cool them completely, fridge-cold if possible, before combining. I will make my onions the day before I need them, which makes throwing this dip together simple.

Yes. In fact, it tastes better the next day, once the onions and yogurt have had time to sit together.

Yes. The onions are the base of this recipe's flavor, not a garnish, so the full caramelizing time matters.

Up to 5 days in an airtight container. The flavor actually improves after the first day.
