There’s just something magical about Caramelized Onion Dip—it’s creamy, savory, and packed with deep, rich onion flavor. Whether you’re hosting a party, planning a cozy movie night, or just craving something delicious, this dip is the perfect choice. Plus, it’s incredibly easy to make with just a few simple ingredients!
Now, here’s the secret: slow-cooked caramelized onions. Taking the time to cook them low and slow brings out their natural sweetness, creating a depth of flavor you just can’t get any other way. Combined with tangy sour cream, smooth cream cheese, and a touch of Worcestershire, this dip is bold, balanced, and absolutely irresistible.
A fun fact? Onion dips became popular in the 1950s when home cooks started mixing dry onion soup mix into sour cream for a quick and easy party snack. But homemade versions, like this one, take it to the next level with real caramelized onions for a gourmet twist.
So, grab some chips, crackers, or fresh veggies, because once you try this Caramelized Onion Dip, you’ll be hooked. Let’s get dipping!

Recipe Yield: About 2.5 cups (serves 6-8 as a dip)
INGREDIENTS
8 oz cream cheese, softened
2 large yellow onions, finely sliced
1 cup sour cream (full-fat for richness)
1/2 cup mayonnaise
2 tbsp unsalted butter
1 tbsp olive oil
1/2 tsp garlic powder
1/4 tsp onion powder
1/2 tsp salt (plus more to taste)
1/2 tsp black pepper
1 tsp Worcestershire sauce
1/2 tsp lemon juice
1 tbsp chopped fresh chives (for garnish)
1/2 tsp cayenne pepper (optional)
INSTRUCTIONS
1. Caramelize the onions: In a large skillet over medium-low heat, melt butter with olive oil. Add sliced onions and stir to coat. Cook slowly for 30-40 minutes, stirring occasionally, until onions become deeply golden brown and jammy. Sprinkle in salt, pepper, garlic powder, and onion powder, then stir in Worcestershire sauce. Remove from heat and let cool completely.
2. Blend the dip base: In a mixing bowl, beat together cream cheese, sour cream, and mayonnaise until smooth and creamy. Stir in the cooled caramelized onions, cayenne pepper (if using), and lemon juice. Mix well to combine.
3. Chill & serve: Transfer the dip to a serving bowl, cover, and chill for at least 2 hours (overnight is best) to let the flavors meld beautifully. Before serving, sprinkle with chopped chives for a pop of color and freshness.
Helpful Tips to Perfect This Recipe
- Patience is Key: For the best flavor, let the onions cook low and slow—rushing will result in bitter, underdeveloped caramelization.
- Let it Rest: This dip tastes best when chilled for a few hours. The flavors deepen beautifully over time!
- Serving Ideas: Pair with kettle-cooked chips, pretzels, crostini, or fresh veggies for the ultimate dip experience.
