Prep the garlic: Grate or mince the garlic very finely. The smaller the pieces, the smoother and less harsh the flavor will be.
Mix the base: In a medium bowl, combine the Greek yogurt, olive oil, lemon juice, and lemon zest.
Stir until glossy and smooth.
Add flavor: Fold in the garlic, dill, chives, salt, pepper, and red pepper flakes if using. Taste and adjust the lemon and salt.
Let it rest: Cover and refrigerate for at least 20–30 minutes. This helps the garlic mellow and the herbs bloom.
Finish and serve: Give it a quick stir.
Drizzle with a little olive oil and a sprinkle of herbs. Serve with sliced cucumbers, bell peppers, warm pita, or roasted potatoes.
