Step-by-Step Instructions for Roasted Garlic Potatoes Au Gratin
Step 1: Roast the Garlic
Roasted garlic is the star of this recipe, providing a sweet-savory depth that enhances the dish.
- Preheat your oven to 375°F (190°C).
- Slice the top off a head of garlic to expose the cloves.
- Drizzle 1 tablespoon of olive oil over the exposed cloves and sprinkle with a pinch of salt.
- Wrap the garlic head in foil and roast for 30 minutes until soft and golden.
- Let it cool, then gently squeeze the garlic cloves out of their skins and mash them into a paste. Set aside.
Why This Matters: Roasting mellows the garlic’s sharpness and enhances its sweetness, infusing the entire gratin with flavor.
