Start by crumbling your feta cheese into smaller pieces. If your feta came in a block with brine, make sure to pat it dry with a paper towel before adding it to your food processor. This ensures that the dip stays thick and creamy rather than becoming too watery.
Place the crumbled feta, Greek yogurt, olive oil, lemon juice, and lemon zest into a food processor or a high speed blender. Pulse the mixture several times to break down the cheese, then blend on high for about one to two minutes. You are looking for a silky smooth consistency with no large chunks remaining.
Continue to process the mixture for another thirty seconds. This helps incorporate air into the dip, giving it that light and fluffy whipped texture that makes it so spreadable. Taste the mixture and add a pinch of salt if needed, though usually the feta provides plenty of saltiness on its own.
Spread the whipped feta onto a shallow serving bowl or a decorative plate using the back of a spoon to create attractive swirls and wells. Drizzle the honey generously over the top so it pools in the grooves. Sprinkle the chopped pistachios, red pepper flakes, and fresh herbs over the surface for a beautiful finish.
