Gather all your ingredients, ensuring that the peaches are washed and peeled. Dice the peaches into smaller pieces for easier blending.

In a blender, combine the diced peaches, honey (or maple syrup), Dijon mustard, and balsamic vinegar. Blend on high for about 30 seconds until smooth.

With the blender running on low, slowly drizzle in the olive oil. Blend for another 20–30 seconds until the vinaigrette is silky and combined.

Add salt and pepper to taste, blending briefly to incorporate the seasonings, then adjust as necessary.

Transfer to a serving bowl or store in an airtight container in the fridge for up to one week. Shake well before use.
