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.
Refrigerate leftovers in shallow containers within 2 hours (1 hour above 90°F); use within 3–4 days. Reheat the center to 165°F.
