French Onion Creamy Dip

This French onion dip is a creamy, flavorful crowd-pleaser perfect for parties or a cozy night in. The slow caramelized onions bring a rich sweetness that balances beautifully with the tangy yogurt and sour cream base. It’s a recipe I've returned to again and again because it transforms simple ingredients into something special everyone loves.

I first made this dip for a family get-together and it disappeared before the chips did. Now it’s a go-to whenever I want an easy, tasty snack.

Ingredients

• Butter and olive oil: Cook together to slowly caramelize onions adding sweetness and depth. Choose unsalted butter for better control over salt.
• Yellow onions: Use large yellow onions for their natural sweetness and ability to caramelize without burning. Look for firm onions with dry skins.
• Plain Greek yogurt: Adds creaminess and tang while keeping the dip lighter. Full fat yogurt results in richer flavor.
• Sour cream: Balances tanginess and smoothness in the dip. Opt for good quality fresh sour cream.
• Mayonnaise: Brings a velvety texture and richness to the mix. Use a classic style for best flavor.
• Garlic cloves: Fresh minced garlic gives a bright pungency. Avoid pre-minced which can be harsh.
• Fresh chives: Add subtle oniony-herb flavor and a fresh green color. Choose bright green stems free from wilting.
• Kosher salt: Enhances all flavors without overpowering. Use quality coarse salt that is easy to measure.
• Fresh cracked black pepper: Gives a mild heat and aroma in the background. Freshly cracked is preferable for best flavor.

Instructions

Caramelize the Onions:

Heat butter and olive oil in a sauté pan over low heat until melted and warm. Add the finely chopped yellow onions stirring to coat in the fat. Cook slowly on low heat for about 30 minutes stirring every few minutes. Watch carefully to avoid burning and allow the onions to reach a deep golden brown color. The slow cooking draws out sugars and creates that rich caramel flavor. Remove the onions from heat and transfer to a bowl to cool.

Combine the Dip Base:

In a large mixing bowl combine the Greek yogurt, sour cream, mayonnaise, minced garlic, chopped fresh chives, and kosher salt. Stir well until the mixture is smooth and uniform in texture.

Mix the Onions Into the Dip:

Add the cooled caramelized onions to the creamy base and fold in gently. Taste and adjust seasoning by adding more salt and freshly cracked black pepper to suit your preference. For a pretty presentation reserve a small amount of onions and chives to sprinkle on top right before serving.

Chill and Serve:

Cover the dip and refrigerate it for at least 30 minutes to let all the flavors meld together. Serve chilled with a selection of chips, crackers, or fresh vegetables.

My favorite ingredient has to be the caramelized onions. That long, slow cooking process turns humble onions into something utterly indulgent and sweet. I remember making this dip for my niece’s birthday party and watching all the kids dip their veggies with big grins. It was one of those simple moments that make cooking so rewarding.

Storage Tips

Store leftovers in an airtight container in the refrigerator where it will keep fresh for up to 5 days. Always use a clean spoon when serving to avoid contamination. If you want to keep the dip longer freeze in a sealed freezer-safe container for up to 2 months. Thaw overnight in the fridge before serving and give it a quick stir.

Ingredient Substitutions

Swap Greek yogurt for cream cheese if you prefer a thicker and tangier dip. For a dairy-free version use coconut yogurt and vegan mayo but be aware the flavor will change. Use shallots instead of yellow onions for a milder, slightly sweeter taste, adjusting caramelizing time as shallots cook faster.

Serving Suggestions

Serve with crunchy potato chips like ruffles or kettle-cooked for an irresistible combo. It also pairs well with pretzel thins, pita wedges, crackers, or fresh crudités like carrot sticks and bell pepper strips. Leftover dip is fantastic spread on burgers or sandwiches adding moisture and flavor.

Seasonal Adaptations

In summer add chopped fresh herbs like dill or parsley for brightness. In winter, enhance warmth with a pinch of smoked paprika or cayenne pepper in the dip. You can mix in roasted garlic instead of raw for a mellower garlic flavor in cold months.

This dip is sure to be a crowd-pleaser no matter the occasion. Enjoy creating and sharing it with family and friends.
