Cheesy Mashed Potatoes with Gouda and Crispy Pancetta
Vegetarian? Use an equal amount of chopped artichoke hearts to replace the pancetta. Not a fan of Gouda? Replace it with smoked mozzarella. No green onions? Substitute fresh chives or Italian (flat-leaf) parsley.
To Make Ahead
Prepare as directed through Step 3. Transfer mashed potatoes to a greased 2-quart baking dish. Cover and chill for up to 24 hours. Preheat oven to 350°F. Bake, covered with foil, for 40 to 45 minutes or until heated through.
