HOW TO MAKE CLASSIC ONION DIP

Ingredients

• 2 large yellow onions, thinly sliced
• 2 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 teaspoon salt, divided
• ½ teaspoon black pepper
• 1 teaspoon Worcestershire sauce
• 1 ½ cups full-fat sour cream
• ¾ cup mayonnaise (good quality)
• ¼ teaspoon garlic powder
• Fresh chives, finely chopped (for garnish)


Directions

• First, melt the butter and olive oil together in a large skillet over medium-low heat. Add the thinly sliced onions and sprinkle with ½ teaspoon of the salt.
• Now, cook the onions, stirring occasionally, for at least 35-45 minutes. You want them to slowly turn a deep, golden brown, caramelizing and becoming sweet. Reduce the heat if they start to burn. This step is non-negotiable for the best flavor!



• Once the onions are beautifully caramelized, remove the skillet from the heat. Stir in the Worcestershire sauce and the remaining ½ teaspoon of salt and black pepper. Let them cool completely.
• Meanwhile, in a medium mixing bowl, combine the sour cream, mayonnaise, and garlic powder. Stir until smooth and well-blended.
• Next, once the onions are cool, chop them finely. You want little bursts of flavor, not long strings. Add the chopped caramelized onions to the sour cream mixture.
• Finally, fold everything together until evenly combined. Cover the bowl and refrigerate for at least 1 hour, or ideally overnight, to let the flavors meld beautifully.
• When ready to serve, transfer to a serving bowl, garnish with a generous sprinkle of fresh chives, and watch it become the star of the party.



NUTRITION AND HEALTH CONSIDERATIONS

A Note on Ingredients

This Classic Onion Dip is an indulgent, celebratory dip, and it’s meant to be enjoyed as such. Using full-fat dairy is key for the proper luxurious texture and flavor that won’t separate. The good news is that, because the flavor is so rich and satisfying, people tend to be satisfied with a smaller portion.

Lighter Swaps

If you prefer a lighter version, you can use light sour cream and light mayonnaise. The texture will be slightly less decadent, but the deep flavor from the caramelized onions will still shine through. For a dairy-free version, try using a high-quality, plain vegan sour cream alternative.

HOW TO SERVE CLASSIC ONION DIP

The Classic Chips and Dip

You simply cannot go wrong with a big, sturdy ridged potato chip. The salt and crunch are the perfect vehicle for the cool, creamy dip. For a homemade touch, serve it with an array of thick-cut kettle chips or even crispy roasted potato wedges.

Beyond the Chip Bowl

This dip’s talents go far beyond the chip bag! Serve it as a spread on burgers or in sandwiches for an incredible flavor boost. It’s also fantastic as a topping for baked potatoes, a dip for crunchy fresh vegetables like radishes and celery, or even as a rich condiment alongside grilled steak.

HOW TO STORE CLASSIC ONION DIP

Refrigeration

Store any leftover dip in an airtight container in the refrigerator. It will keep beautifully for up to 4 days. In fact, it often tastes even better on the second day as the flavors continue to develop. Give it a quick stir before serving again.

Make-Ahead Tips

Honestly, this Classic Onion Dip is the ultimate make-ahead party food. You can prepare the dip completely 1-2 days in advance. Just hold off on garnishing with the fresh chives until you’re ready to serve. The long rest in the fridge only improves the flavor, making your party day even easier.

TIPS TO MAKE CLASSIC ONION DIP

Tips and Notes: Your Kitchen Companion

• Patience with the Onions: Don’t rush the caramelization. Low and slow is the only way to develop that deep, sweet, umami-rich flavor. If the onions start to stick, add a tiny splash of water to the pan.
• Cool Completely: Ensure your caramelized onions are completely cool before mixing them into the dairy. Warm onions will make the dip runny.
• Taste and Adjust: Before chilling, taste your dip. You might want an extra pinch of salt, another dash of Worcestershire, or even a tiny squeeze of lemon juice to brighten it up.



Details

The type of onion matters. Yellow onions are ideal for their balanced sweetness and pungency when cooked. Avoid sweet onions like Vidalias, as they can become too sweet and lack the savory depth we’re after.

Variation

For a fun twist, try adding a pinch of smoked paprika to the sour cream base. For a “French Onion” vibe, stir in a tablespoon of grated Gruyère cheese. If you love texture, reserve a tablespoon of the chopped caramelized onions to sprinkle on top as a garnish.

Notes

If you’re in a serious time crunch, you can use 1 heaping cup of store-bought caramelized onions from the grocery store (often found near the olives or deli). It won’t be quite as good as homemade, but it’s a decent shortcut that still beats the powdered mix.

CLASSIC ONION DIP FAQs

Can I use a slow cooker or Instant Pot for the onions?

Absolutely! For the slow cooker: cook sliced onions with butter on LOW for 8-10 hours until deeply golden. For the Instant Pot: use the Sauté function to soften, then cook on HIGH pressure for 10-12 minutes with a quick release. Both methods work, but stovetop gives you the most control.

Why is my Classic Onion Dip a little runny?

This usually happens if the onions were still warm when mixed in, or if your sour cream had a thinner consistency. To fix it, simply refrigerate the dip for a longer time to let it firm up. You can also stir in an extra tablespoon or two of mayonnaise to help thicken it.

Can I freeze this Classic Onion Dip?

I don’t recommend it. Dairy-based dips like this one can separate and become grainy when thawed. The texture will be compromised. It’s best enjoyed fresh or stored in the fridge for a few days.

This from-scratch Classic Onion Dip (The Party Staple) is more than just a recipe; it’s a gesture of hospitality.
