Poppy-Seed Dressing

This is the classic poppy seed dressing that’s been gracing spinach salads and fruit platters for decades. Sugar and vinegar create a sweet-tart base, dry mustard adds a warm bite underneath, and onion juice gives it a savory dimension that keeps it from tipping into dessert territory.

The technique is what matters most here. The oil must be added in a slow, steady stream while you beat constantly. That gradual emulsion is what transforms thin, watery ingredients into a thick, creamy dressing that clings to greens and fruit. Rush it and you’ll get a broken, oily mess.

Poppy seeds go in last, beaten for a few extra minutes so they’re evenly distributed throughout. Their mild, nutty crunch is the signature texture.

Kitchen Tips

• Pour the oil in the thinnest stream possible while beating. A measuring cup with a spout helps control the flow.
• Onion juice is key and can’t be skipped. Grate a raw onion over a fine strainer or cheesecloth and press out the juice. Minced onion won’t work here since you need just the liquid flavor, not the texture.
• This makes a large batch (4 ½ cups). It keeps well in the fridge for 2 weeks. Shake or whisk before each use since it will separate.
• The sugar quantity is intentional. Poppy seed dressing is supposed to be noticeably sweet. Cutting the sugar changes the character entirely.

Variations

• Honey version: Replace half the sugar with honey for a rounder, less granular sweetness.
• Citrus poppy seed: Use fresh lemon juice in place of half the vinegar for a brighter, more citrus-forward dressing.
• Raspberry poppy seed: Add a tablespoon of seedless raspberry jam to the base for a berry note that pairs beautifully with mixed greens and strawberries.
