Key Ingredients in This Recipe
- Caramelized onions – While caramelizing onions takes a bit of patience. Don’t try to rush the process by turning up the heat. The goal is to draw out the sugars in the onions and caramelize them – you have to go low and slow. You end up with mellow sweet onion flavor. The onions should be deep in color (a golden brown is best) but not dark – you don’t want to burn the onions. Making them too dark and deeply caramelized risks creating a bitter flavor.
- Sour cream – Sour cream makes a wonderful base for dips and adds a tangy flavor that complements the deep flavor of the caramelized onions and other ingredients in the dip. While many dips use a combination of cream cheese and sour cream or mayonnaise, I opt for just cream cheese for a thinner dip consistency.
- Ginger – To easily peel ginger, use the tip of a spoon to carefully peel away the skin.
- Lemongrass – Lemongrass adds a bright, lemony flavor to dishes. Fresh lemongrass is best for this recipe since it has a more complex flavor. Pre-packaged paste or dried lemongrass can be substituted if needed. Only the bottom yellow part of the lemongrass stalk is used in cooking, the top part is typically much too tough.
- Lime Zest – The lime zest is the grated outer skin from the citrus to add a concentrated flavor. Use a zester or microplane to remove the zest. If you don’t have a zester use a paring knife or vegetable peeler to remove the rind and finely chop it.
- Garlic powder – I add a bit of garlic powder to the dip. Garlic powder has a more concentrated, intense flavor than fresh garlic and quickly deepens the flavor of the dip.

Pro Tip
Caramelize the onions low and slow until they reach a deep golden brown—rushing this step can result in bitter or underdeveloped flavor.
Swaps and Substitutions
- Sour Cream: Swap with full-fat Greek yogurt for a lighter version.
- Red Onion: Use yellow onions for a milder, sweeter onion flavor.
- Fresh Lemongrass: Substitute with lemongrass paste or dried lemongrass if needed.
- Cilantro: Omit or replace with sliced green onions if preferred.
How to Make Caramelized Onion Pho Dip (Step-by-Step)
Heat a large skillet or sauté pan over medium heat, add the olive oil and heat through. Add the butter and allow to melt then add the onions.

In a medium bowl stir together the caramelized onion with the sour cream, cilantro, lime zest, and onion powder. Season to taste with salt.
