Key Ingredients

Here's everything you'll need to make this homemade onion dip.

• Yellow Onions: We rely on these for that deep caramelized base that gives the dip its signature flavor.
• Shallots: Add a slightly sweeter, more refined onion flavor that blends seamlessly with the onions.
• Butter: Helps the onions develop a rich golden brown color.
• Olive Oil: Keeps the butter from burning during the longer cook time.
• Garlic Powder: Reinforces the savory depth without overpowering.
• Onion Powder: Enhances the overall onion flavor without needing more raw onion.
• Sour Cream and Mayonnaise: Creates a tangy, creamy base that balances the sweetness of the onions.
• Cream Cheese: Thickens the dip and gives it that scoopable consistency.
• Worcestershire Sauce: Brings a subtle savory depth that rounds everything out.
• Green Onions (Green Parts): Provide a fresh finish without adding harshness.

Substitutions & Variations

• Spicy: Add a pinch of red pepper flakes while cooking the onions.
• Diet: Use low-fat sour cream and mayo.
• Presentation: Serve in a bread bowl or with a mix of chips and vegetables.
• Budget-Friendly: Use only onions and skip shallots to reduce cost.

How to Caramelize Onions Properly

• Use medium heat and stir occasionally.
• Let onions sit long enough to develop color.
• Add a splash of water if the onions start sticking.
• Look for a deep golden brown color, not pale or burnt.

Storage

Store caramelized onion dip in an airtight container in the refrigerator for up to 4 days. This dip is best served cold and does not freeze well due to the dairy base.

Notes

Cooking Notes

Cook the onions slowly until fully golden for the best flavor. Let them cool completely before mixing to keep the dip smooth.

Tips for Best Results

• Keep the heat moderate so onions caramelize, not burn.
• If needed, add a splash of water to deglaze the pan and scrape up any browned bits.
• Let the dip chill before serving.
• Mix only after onions are fully cooled.

How to Know It’s Ready

The onions should be deep golden brown and very soft. The finished dip should be thick, creamy, and easy to scoop without being runny.
