Dips & Sauces

March 10, 2026

There’s nothing better than a delicious, homemade salad dressing, and this creamy Poppy Seed Vinaigrette is about to become your new favorite! The secret to its silky-smooth texture without any cooking? Using a confectioners’-style sweetener like erythritol. It dissolves instantly, giving you a perfectly sweet and tangy dressing in minutes. If you only have the granulated kind, don’t worry—I’ve got a simple trick for that below! Get ready to ditch the store-bought bottles for good.

Ingredients

• 1 cup / 240 ml light-tasting oil, such as avocado oil or light olive oil
• ¼ cup / 60 ml distilled vinegar
• 2 tablespoons confectioners’-style erythritol, or 10 drops liquid stevia
• 1 tablespoon plus 1 teaspoon poppy seeds
• 2 teaspoons onion powder
• 1 teaspoon Dijon mustard
• ½ teaspoon finely ground sea salt

Instructions

1. Combine all in a 16-ounce / 475 ml (or larger) airtight jar or container.
2. Seal the container tightly and shake vigorously until the dressing is creamy and fully incorporated.
3. Before serving, give the jar another quick shake to re-emulsify. Drizzle over your favorite salad and enjoy!

Pro Tips

• No confectioners’ sweetener? Blend granulated erythritol in a high-speed blender until it becomes a fine powder. This ensures a smooth, grit-free dressing without any heating.
• For a LOW-FODMAP version, simply omit the onion powder. The dressing will still be packed with flavor.
• Store the dressing in an airtight container in the fridge for up to 5 days. The oil may solidify when chilled; let it sit at room temperature for 10-15 minutes and shake well before using.
• This dressing isn’t just for salads! Use it as a delicious marinade for chicken or pork, or as a dip for fresh vegetables.
