Pineapple Beef Marinade

This marinade does everything you want in one mix: the natural enzymes in pineapple juice break down tough muscle fibers in beef, while dark brown sugar, soy sauce, garlic, and ginger build a sweet-savory glaze that caramelizes beautifully on a hot grill or under a broiler.

The flavor profile leans Pacific Rim with the combination of pineapple, soy sauce, ginger, and peanut oil. White pepper and a pinch of cayenne add warmth without overpowering the tropical sweetness.

Let the marinade sit for an hour before using so the sugar dissolves fully and the garlic and spices have time to infuse. Then marinate your beef for at least two hours, but don’t go past eight. Pineapple juice is an aggressive tenderizer and will turn the surface of the meat mushy if left too long.

Chef Tips

• Stir until the brown sugar is completely dissolved. Undissolved sugar won’t distribute evenly and can cause burning during cooking.
• Best on flank steak, skirt steak, or London broil. These tougher cuts benefit most from the tenderizing action.
• Pat the beef dry after removing from the marinade for a better sear. Wet meat steams instead of browning.
• Reserve a small portion of the marinade before adding the beef if you want to use it as a basting sauce.

Variations

• Add a tablespoon of sesame oil for a nuttier, more Asian-forward flavor.
• Swap peanut oil for coconut oil and add a squeeze of lime for a Hawaiian twist.
• Use this same marinade on pork tenderloin or chicken thighs.
