Roasted Garlic Potatoes Au Gratin Recipe FAQs
What type of potatoes work best for Roasted Garlic Potatoes Au Gratin?
Absolutely! Starchy varieties like Russet or Yukon Gold are ideal for this dish, as they create a creamy texture that melts beautifully during baking. They’ll break down slightly, resulting in velvety layers that soak up the roasted garlic flavor perfectly.
How should I store leftover Roasted Garlic Potatoes Au Gratin?
To keep your creamy delight fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. Be sure to let it cool before covering. When you’re ready to enjoy it again, gently reheat in the oven at 350°F (180°C) for about 15-20 minutes until warmed through.
