Step 1: Preheat oven to 400°F (200°C). Place unpeeled garlic cloves on a small baking sheet and roast for 15-20 minutes until soft and golden.
Step 2: Remove garlic from oven and let cool completely. Once cooled, peel and mince the roasted garlic.
Step 3: In a medium bowl, combine olive oil, minced roasted garlic, rosemary, thyme, red pepper flakes, oregano, salt, and black pepper.
Step 4: Whisk the mixture thoroughly until all ingredients are well combined.
Step 5: Add lemon zest and gently stir to incorporate.
Step 6: Let the oil mixture sit at room temperature for at least 30 minutes to allow flavors to meld.
Step 7: Serve in shallow bowls alongside warm, crusty bread for dipping.
