2. Ingredients and Tools for Roasting Garlic
Core Ingredients
1. Fresh Garlic Bulbs:

- Quantity: Depending on the recipe, you may roast one bulb or several.
2. Olive Oil:
- Type: Use extra virgin olive oil for its rich flavor and health benefits.
- Amount: Typically, 1-2 tablespoons of olive oil per bulb of garlic is sufficient.
3. Salt and Pepper:
- Salt: A pinch of sea salt enhances the flavor.
- Pepper: Freshly ground black pepper adds a subtle heat.
Essential Tools
1. Baking Sheet or Pan:
- Material: A baking sheet with a rim or a shallow pan is ideal for roasting garlic.
2. Aluminum Foil or Parchment Paper:
- Foil: Used to wrap garlic bulbs and create a sealed environment.
- Parchment Paper: Useful for lining the baking sheet to prevent sticking.
3. Knife:
- Utility: A sharp knife is needed to trim the tops of the garlic bulbs.
4. Small Dish or Ramekin:
- Purpose: For holding garlic bulbs if not using foil.
3. Preparing and Roasting Garlic
Step-by-Step Guide
3.1. Preparing the Garlic Bulbs
- Trimming the Tops: Using a sharp knife, cut off the top 1/4 inch of each garlic bulb. This exposes the individual cloves and helps the garlic roast evenly.
- Drizzling with Olive Oil: Place the garlic bulbs on a piece of aluminum foil or in a small dish. Drizzle with olive oil, ensuring that the oil seeps into the exposed cloves.
- Seasoning: Sprinkle a pinch of sea salt and freshly ground black pepper over the garlic bulbs. This enhances the flavor and adds a touch of seasoning.
3.2. Roasting the Garlic
- Wrapping in Foil: If using foil, wrap the garlic bulbs tightly in the foil, creating a sealed packet. This helps trap the moisture and promotes even roasting.
- Baking: Place the foil-wrapped garlic on a baking sheet or directly on the oven rack. Roast in a preheated oven at 400°F (200°C) for 30-40 minutes. The garlic is done when it is soft and golden brown, and the cloves can be easily squeezed out.
- Cooling: Allow the roasted garlic to cool slightly before handling. The cloves will be hot and may be easier to handle with a fork or spoon.
- Extracting Cloves: Squeeze the roasted garlic bulbs from the bottom to pop the cloves out. Alternatively, use a small fork or knife to extract the soft cloves.
