This Red Wine Vinegar Steak Marinade is bold, balanced, and designed to bring out deep flavor in every bite of your steak. The sharp tang of red wine vinegar blends beautifully with olive oil to tenderize the meat, while garlic, rosemary, and thyme add that classic herb-forward aroma. A touch of brown sugar rounds everything out with subtle sweetness, and Dijon mustard adds a light depth that enhances the overall richness. It’s a simple marinade, but one that delivers restaurant-style results with minimal effort.
