Batch-cook these protein-packed muffins on Sunday and you’ll have grab-and-go lunches or freezer-ready dinners for weeks. The individual portions invite endless twists—swap in ground turkey, fold in shredded veggies, or top with spicy barbecue sauce to keep every bite fresh.
Lean ground beef (90 % lean or higher) 1 pound
Preheat the oven to 350°F
Chef’s Note
Line the muffin cups with 4-inch squares of parchment before filling; the paper “slings” make it easy to lift the minis out intact and keep the glaze from sticking. For extra juiciness, grate ¼ cup onion directly into the meat mixture—its liquid replaces some of the milk and disappears into the loaf. Cool the muffins completely, then flash-freeze on a sheet pan; once solid, transfer to a freezer bag and reheat straight from frozen at 350°F for 15–18 minutes.
