Key Ingredients & Substitutions
Yellow Onions: These are perfect for caramelizing due to their natural sweetness. If you’re in a pinch, sweet onions or even red onions can work, but they may impart a different flavor.
Olive Oil & Butter: This combo helps achieve that delicious flavor and texture when cooking. If you’re looking to reduce fat, use more olive oil or even a non-stick cooking spray, but keep in mind it may change the taste.
Sour Cream: It gives the dip a creamy base. Plain Greek yogurt can be a healthier substitute while offering similar creaminess.
Cream Cheese: This adds richness to the dip. If you’re looking for a lighter option, try using low-fat cream cheese or whipped cream cheese for easier mixing.
Mayonnaise: It keeps the dip smooth. For a lighter version, you could use Greek yogurt again, or even avocado for an interesting twist.
How Do I Perfectly Caramelize Onions?
The key to caramelizing onions is patience! You really want to take your time to develop that sweet flavor. Here are some steps to follow:
- Heat the skillet over medium heat; add olive oil and butter until melted.
- Add sliced onions and 1/2 tsp salt, which helps draw out moisture.
- Cook for 30-40 minutes, stirring occasionally, and lower the heat if they start to burn.
- For added sweetness, sprinkle in the sugar halfway through cooking.
- Once they’re golden and caramelized, let them cool before mixing into the dip.
Taking your time with the onions results in that sweet, rich flavor that really makes this dip shine!

- 1 tbsp unsalted butter
- 1 tsp salt, divided
- 1/4 tsp black pepper
- 1 tsp sugar (optional, to aid caramelization)

How Much Time Will You Need?
This delicious caramelized onion dip takes about 40 minutes of preparation time, plus an additional hour to chill in the refrigerator. The cooking time allows the onions to caramelize to perfection, while the chilling time merges all those wonderful flavors together for an irresistible dip!
Step-by-Step Instructions:
1. Caramelize the Onions:
Start by heating the olive oil and butter in a large skillet over medium heat. Once melted and shimmering, add the sliced onions and sprinkle in 1/2 tsp of salt. Stir occasionally and let the onions cook for about 30-40 minutes, until they turn a beautiful golden brown and become nicely caramelized. If you’re using sugar, add it halfway through to enhance sweetness. Keep an eye on the heat to prevent burning—adjust as necessary!
2. Cool the Onions:
Once your onions are perfectly caramelized, take the skillet off the heat and let them cool down to room temperature. This is important so they don’t warm up your dip later!
3. Mix the Creamy Base:
In a mixing bowl, combine the sour cream, softened cream cheese, and mayonnaise. Use a hand mixer or a sturdy spoon to beat the mixture until it’s nice and smooth. Then, add the minced garlic, finely chopped parsley, Worcestershire sauce (if you like) and black pepper. Mix everything together well.
4. Combine the Ingredients:
Next, fold in the cooled caramelized onions, but remember to save a little to garnish the top! This adds a lovely touch when serving.
5. Chill the Dip:
Transfer your dip to a serving bowl and garnish with the reserved onions and some extra parsley for color. Cover it up and pop it in the fridge for at least 1 hour. Chilling allows all the flavors to blend beautifully!
6. Serve and Enjoy:
When ready to enjoy, take the dip out and serve it chilled with your favorite crackers, chips, or fresh veggies. Everyone is going to love this creamy, savory treat!
Enjoy every bite of your homemade caramelized onion dip—it’s perfect for sharing at parties or enjoying on game night!
