Grilled Marinated Steak

This grilled steak is a meal-prep genius move. Sirloin steaks go into a freezer bag with the marinade, get frozen, and the marinating happens while the meat thaws. By the time it’s defrosted, it’s already seasoned and ready for the grill. Zero day-of prep work.

The marinade is simple and punchy: red wine vinegar for acidity, Worcestershire sauce for deep, savory umami, crushed garlic for bite, and a tablespoon of oil to help everything cling to the meat. No sugar, no sweetness. This is an all-savory marinade that lets the beefy flavor of sirloin stay front and center.

Red wine vinegar is a natural tenderizer. The acid breaks down tough muscle fibers during the long freeze-and-thaw marination, so even a lean sirloin comes out more tender than it would from a quick marinade. The extended contact time (hours of thawing) gives the vinegar and Worcestershire plenty of time to penetrate deep into the meat.

Grill to medium rare for the best balance of seared exterior and juicy, pink center. Discard the marinade completely after thawing. It’s been in contact with raw meat and should never be served as a sauce.

Pro Tips

• Cut the steak into three pieces before freezing. Smaller pieces thaw faster and more evenly than one large slab.
• Squeeze as much air out of the freezer bag as possible. Air in the bag causes freezer burn and uneven marination.
• Thaw in the refrigerator, not on the counter. Slow thawing gives the longest marination time and keeps the meat at safe temperatures.
• Pat the thawed steaks dry before grilling. Excess marinade on the surface creates steam and prevents a good sear.

Variations

• Add a tablespoon of soy sauce to the marinade for an Asian-inspired umami boost.
• Mix in a teaspoon of smoked paprika or cumin for a Southwestern flavor profile.
• Use flank steak or skirt steak instead of sirloin. Both take well to acidic marinades and grill beautifully.
