This Caramelized Onion Dip is super creamy and packed with sweet, golden onions. It’s perfect for your next party or just for snacking on while binge-watching your favorite show!
You can pair it with chips, veggies, or even spread it on toast. It’s so tasty, I’m pretty sure it will disappear faster than I can make it! 😂
Key Ingredients & Substitutions
Yellow Onions: These are perfect for caramelizing due to their natural sweetness. If you want a sharper flavor, you can swap them with red onions, but they might not get as sweet.
Butter & Olive Oil: I like using both for the flavor and this combo helps achieve great caramelization. You can use all butter or all olive oil if that’s what you have on hand.
Sour Cream & Mayonnaise: These create a smooth and creamy base. For a lighter option, try Greek yogurt. If you’re dairy-free, look for vegan mayo or yogurt alternatives.
Herbs: Chives and dill add freshness. If you don’t have chives, try green onions or parsley instead. Dill can be replaced with dried herbs like thyme for a different flavor.
How Do I Caramelize Onions Like a Pro?
Caramelizing onions takes time but it’s worth it for the tremendous flavor. Here’s how to do it right:
- Start with medium-low heat; cooking too fast can burn the onions.
- Add 1/4 teaspoon of salt to help draw out moisture from the onions.
- Stir occasionally—every few minutes—to prevent sticking and promote even cooking.
- Be patient! It may take 25–35 minutes for them to turn golden brown. If they seem dry, add a splash of water!
Once they’re perfectly caramelized, let them cool down before mixing into your dip. This helps keep the dip creamy!

- 1/2 teaspoon sugar (optional, helps with caramelization)
- 1 cup sour cream
- 1/2 cup mayonnaise
- 1 teaspoon fresh lemon juice

How Much Time Will You Need?
This delicious Caramelized Onion Dip takes about 45 minutes to prepare—30 minutes for caramelizing the onions and approximately 15 minutes to mix everything together. Plus, don’t forget to chill the dip for at least 1 hour before serving to let those flavors mingle and develop. Your patience will pay off!
Step-by-Step Instructions:
1. Caramelizing the Onions:
In a large skillet, melt the butter and olive oil over medium-low heat until hot and shimmering. Add the thinly sliced onions along with 1/4 teaspoon of salt. Stir well so the onions are coated in the butter and oil. Now, ready your patience! Cook the onions gently for about 25-35 minutes, stirring occasionally. We want them to become beautifully golden brown and caramelized. If they start to stick to the pan or dry out, add a splash of water to help deglaze the pan. You can also sprinkle in the sugar halfway through if you want them extra sweet!
2. Mixing the Dip Ingredients:
Once your onions are perfectly caramelized, remove the skillet from heat and let those golden beauties cool completely. While they cool, grab a mixing bowl and combine the sour cream, mayonnaise, lemon juice, garlic powder, the remaining 1/4 teaspoon of salt, and the black pepper. If you’re using the dill, toss that in as well! Stir everything together until it’s nice and smooth.
3. Bringing It All Together:
Now it’s time for the star of the show! Fold the cooled caramelized onions into the sour cream mixture, but remember to save some onions for garnishing later. Once everything is combined, transfer the dip to a serving bowl. Garnish with the reserved caramelized onions and extra chives on top for that pop of color.
4. Chilling & Serving:
Pop the dip in the fridge for at least 1 hour to let all those wonderful flavors come together. When you’re ready to dig in, serve it up with your choice of crackers, chips, or fresh vegetables for dipping. Enjoy this creamy, dreamy dip with friends or just keep it all to yourself—no judgment here!
Can I Use Red Onions Instead of Yellow Onions?
Yes, you can use red onions! They have a sharper flavor and won’t caramelize as sweetly as yellow onions, but they will still work well in the dip.
What’s a Good Way to Store Leftovers?
Store any leftover dip in an airtight container in the refrigerator. It will stay fresh for about 3–5 days. Just give it a quick stir before serving again!
Can I Make This Dip Vegan?
Absolutely! You can substitute the sour cream and mayonnaise with vegan alternatives, such as cashew cream or coconut yogurt, for a delicious dairy-free version.
How Do I Caramelize Onions Without Burning Them?
To achieve perfect caramelized onions, cook them over medium-low heat and be patient! Stir occasionally to prevent sticking, and add a splash of water if they start to dry out.
