2. Ingredients Breakdown

Onions

Yellow onions work best because they caramelize beautifully and offer natural sweetness. White onions can be used for a sharper flavor, while red onions add color but a less traditional taste.

Butter

Butter helps the onions caramelize and adds richness. You can also use oil, but butter brings a deeper flavor.

Olive Oil

Using a mix of butter and oil prevents burning during the slow caramelization process.

Sour Cream

The base of the dip. It adds tanginess and creaminess that balances the sweetness of the onions. Greek yogurt can be substituted for a lighter version.

Cream Cheese

Adds body and thickness. If you prefer a looser dip, reduce the cream cheese slightly.

Mayonnaise

Just a small amount enhances creaminess and rounds out the flavors without making the dip taste like mayo.

Garlic

Fresh or minced garlic brings depth. Roasted garlic can be used for a sweeter, milder flavor.

Worcestershire Sauce

A classic addition for savory depth. If vegetarian, replace with soy sauce or tamari.

Salt and Pepper

Essential for balancing the flavors. Add gradually and taste as you go.

Fresh Chives

Chives add color and a fresh onion flavor. Green onions can be substituted.

Optional Add-Ins

Smoked paprika for a smoky twist
Cayenne for mild heat
Caramelized shallots for extra sweetness
Thyme for herbaceous notes

3. Step-By-Step Instructions

Step 1: Caramelize the Onions

In a large skillet, melt the butter with the olive oil over medium heat. Add sliced onions and a pinch of salt, then reduce the heat to medium-low. Cook slowly for 25–35 minutes, stirring occasionally. The onions should turn golden brown and soft, not burnt. If they start to dry out, add a splash of water.

Tip: The key to great French Onion Dip is patience during caramelization. Slow cooking develops sweetness and depth.

Step 2: Add Garlic and Seasonings

Once the onions are caramelized, stir in the garlic and cook for another 1–2 minutes until fragrant. Add Worcestershire sauce and stir to combine. Remove from heat and let cool completely before adding to the dip base.

Step 3: Prepare the Creamy Base

In a mixing bowl, combine the sour cream, cream cheese, and mayonnaise. Beat until smooth and creamy. Let the cream cheese soften at room temperature first to avoid lumps.

Step 4: Fold in the Caramelized Onions

Once the onions are cool, fold them gently into the cream mixture. Make sure they’re evenly distributed.

Step 5: Season to Taste

Add salt, pepper, and additional Worcestershire sauce if needed. Taste and adjust gradually.

Step 6: Chill the Dip

Cover and refrigerate for at least 1 hour. This allows the flavors to meld and deepen.

Step 7: Serve

Top with chopped chives before serving. Stir gently and place in a serving bowl alongside chips, vegetables, or bread.
