A delicious top round steak with green peppers and onions.
Adding the sliced onions and green bell peppers during the final five minutes of cooking prevents them from dissolving into mush. Top round is a lean cut requiring careful moisture management. Smashing garlic cloves together with chicken bouillon in a mortar creates a cohesive paste that distributes sodium and aromatics evenly across the meat fibers. Rinsing the steak and splashing vinegar over the surface before marinating introduces mild acidity. This acid helps break down tough connective tissue during refrigeration.
Cooking this dish in a covered frying pan traps steam alongside the olive oil and white wine. That combination of dry and wet heat softens the lean beef. Monitor the liquid level in the pan to prevent scorching. Without a thermometer, determine doneness by pressing the center of the steak. Firm resistance indicates medium-well, while a soft center means the meat remains rare.
