Directions
Combine all —oil, strawberries, balsamic vinegar, Dijon mustard, lemon juice, garlic, shallot, salt, pepper, and red pepper flakes—in a blender or food processor.
Pulse or blend on high until the mixture is well combined and completely smooth.
Transfer the vinaigrette to an airtight container or jar and store it in the refrigerator for up to 2 weeks.
Taste and adjust sweetness. If your strawberries are tart, consider adding a teaspoon of honey or maple syrup to balance the flavors.
Let the vinaigrette rest in the refrigerator for at least 30 minutes before serving to allow the flavors to fully meld together.
