Ingredients
Method
- Heat oven to 375°F; butter a deep 9x13-inch dish. Slice potatoes uniformly with a guarded mandoline or sharp knife; do not substitute thick chunks.
- Warm cream, milk, garlic, thyme, nutmeg, salt and pepper in a saucepan until steaming, not boiling.
- Layer half the potatoes, slightly overlapping, in dish. Add half the ham and 1/2 cup cheese. Repeat potatoes and remaining ham; pour warm cream mixture evenly over everything. Top with remaining 1 cup cheese.
- Cover tightly with foil; bake 55–65 minutes. Uncover; bake 15–20 minutes until a knife slips easily through center potatoes, top is golden and filling reaches 165°F. Re-cover if browned before potatoes soften. Rest 10 minutes.
Notes
Equipment: 9x13-inch baking dish, large skillet, large mixing bowl, instant-read thermometer.
Serving size: 1/6 of the recipe.
For freezer meals, divide the baked casserole into shallow portions and refrigerate promptly, within 2 hours. Once cold, wrap airtight and freeze for up to 2 months for best texture. Thaw overnight in the refrigerator. Reheat thawed portions covered at 350°F for about 25–35 minutes, until the center reaches 165°F; larger portions take longer. Use a metal pan or follow your baking-dish manufacturer’s temperature-change directions.
Freeze after baking, when potatoes are completely tender. The sauce may look slightly separated after thawing; reheat gently, covered.
Refrigerate leftovers in shallow containers within 2 hours (1 hour above 90°F); use within 3–4 days. Reheat the center to 165°F.
