Whether you serve it with crisp potato chips, bagel chips, or fresh veggie sticks, this dip disappears fast. With simple ingredients and a few key techniques, you can create a dish that feels gourmet while still being incredibly approachable.

Why This Caramelized Onion Dip Stands Out

Texture: Creamy and smooth with a luscious richness from the cream cheese and sour cream, perfectly complemented by crisp, crunchy chips or dippers.

Flavor: Sweet, deeply caramelized onions balance the tang of sour cream and the savoriness of mayonnaise, while garlic, spices, and a touch of Worcestershire sauce add layers of depth.

Ease of Preparation: Caramelizing onions takes some patience, but the process is straightforward. Once the onions are golden and fragrant, mixing the dip is quick and easy.

Make-Ahead Friendly: Preparing this dip a day in advance allows the flavors to intensify, making it even more delicious when served.

Ingredients Overview

Understanding the key ingredients helps ensure your dip comes out perfect every time.

• Sour Cream: Full-fat sour cream works best, providing creaminess and tang. Greek yogurt can be substituted for a slightly lighter option.
• Mayonnaise: A good-quality mayo enhances flavor; avoid overly processed brands for the best taste.
• Cream Cheese: Use softened cream cheese for a smooth, well-blended dip.
• Onions: Sweet yellow onions, such as Vidalia, caramelize beautifully and give a naturally sweet flavor.
• Shallots: Adding shallots deepens the flavor without overpowering the sweetness of the onions.
• Worcestershire Sauce: Adds a subtle umami note; check labels if gluten-free is required.
• Spices and Herbs: Salt, pepper, cayenne, and garlic create a savory balance, and chives provide a fresh finishing touch.

Step-by-Step Instructions

Step 1: Caramelize the Onions

Start by melting butter in a large skillet over medium heat. Add thinly sliced onions, diced shallots, salt, pepper, and a pinch of cayenne. Sauté for about 10 minutes until they begin to soften.

Reduce the heat to medium-low and cook slowly for another 20-25 minutes, stirring occasionally. The goal is a deep golden brown color and a rich, sweet aroma. Add minced garlic during the last 1-2 minutes of cooking, then remove from heat and let cool.

Tip: Using a mandolin slicer ensures ultra-thin, uniform onion slices, which caramelize evenly and give the dip a luxurious texture.

Step 2: Prepare the Dip Base

In a medium mixing bowl, combine softened cream cheese, sour cream, and mayonnaise. Mix until smooth, using an electric mixer for best results or a spoon if the cream cheese is very soft.

Add celery salt, Worcestershire sauce, lemon juice, and additional salt and pepper to taste. Stir well to incorporate all the flavors.

Step 3: Combine Onions and Dip

Once the onions have cooled to room temperature, fold them into the cream mixture until fully incorporated. Cover the bowl and refrigerate for at least one hour, or overnight for even richer flavor.

Before serving, give the dip a gentle stir and sprinkle with minced chives for a fresh, vibrant touch. Serve alongside your favorite chips or dippers.

Storage and Make-Ahead Tips

• Refrigeration: Store leftovers in an airtight container for up to five days.
• Make-Ahead: This dip improves in flavor when made a day in advance. Simply refrigerate until ready to serve.
• Freezing: Avoid freezing, as the creamy texture does not hold up well after thawing.

Variations and Tips

• Dairy-Free Option: Substitute with vegan butter, dairy-free cream cheese, sour cream, and mayonnaise for a plant-based version.
• Alternative Cooking Fats: Butter provides a richer caramelized flavor, but olive oil can be used for a lighter option.
• Extra Sweetness: While natural onion sugars are usually enough, a small pinch of brown sugar can speed up caramelization and enhance sweetness.
• Serving Ideas: Beyond classic potato chips, try pita chips, tortilla chips, corn chips, or fresh vegetables like carrots, cucumbers, and bell peppers.
