Best 7 Grilled Balsamic Onions Recipes

GRILLED BALSAMIC FLANK STEAK WITH PEPPERS AND ONIONS

Steps:

• Generously season steak with salt and pepper. In a large resealable bag, combine vinegar, Worcestershire, mustard, brown sugar, and oil. Rub rosemary sprigs between your palms for a few seconds to release oils, then transfer to bag. Add steak, onion, and bell peppers; remove excess air from bag, seal, and shake until marinade evenly coats meat and vegetables. Refrigerate at least 12 hours and up to 2 days.
• Remove steak and vegetables from refrigerator 1 hour before grilling. Preheat grill for direct-heat cooking. Brush grates with oil. Using tongs, remove steak from bag, allowing excess marinade to drip back in. Grill, turning a few times, until charred in places and a thermometer inserted into thickest part registers 125 degrees for medium-rare, 8 to 12 minutes, depending on thickness. Transfer to a plate; tent with foil and let stand at least 10 minutes before slicing. Meanwhile, remove vegetables from marinade and grill, turning a few times, until charred in places and tender, 10 to 12 minutes. Toast bread on grill just until charred and crisp in places, about 1 minute a side. Thinly slice steak; serve with vegetables and bread.

Steps:

• Melt 6 tablespoons butter in heavy small saucepan over medium heat. Add minced shallot and cook until translucent, about 2 minutes. Add vinegar and rosemary and simmer until syrupy and reduced to 1/2 cup, about 6 minutes. Remove from heat (balsamic sauce will separate as it stands).

• Sprinkle steaks with salt and pepper. Grill sweet onions, shallots, leeks, and green onions until tender, turning often, about 5 minutes for green onions and 10 minutes for sweet onions, shallots, and leeks. Move onions to cooler part of grill to keep warm. Grill steaks to desired doneness, about 7 minutes per side for medium-rare. Transfer steaks and onions to platter; cover.
• Remove rosemary sprigs from balsamic sauce; add orange juice and bring to simmer. Remove saucepan from heat; add remaining 2 tablespoons chilled butter and whisk until melted and sauce is smooth. Season sauce to taste with salt and pepper. Drizzle some of sauce over steaks and onions. Serve, passing remaining sauce separately.

GRILLED BALSAMIC-MARINATED LONDON BROIL WITH RED ONIONS

Steps:

• Marinate steak and prepare onions:
• Stir together garlic, 3 tablespoons vinegar, 1 1/2 tablespoons oil, 1 1/2 teaspoons salt, and 1/2 teaspoon black pepper and pour into a 1-quart sealable plastic bag.
• Add steak to marinade, turning to coat, and marinate, chilled, turning bag occasionally, at least 4 hours.
• Bring to room temperature, then remove steak from marinade and discard marinade.
• Trim root ends of onions slightly, leaving them intact, then halve lengthwise and cut halves lengthwise into 3/4-inch-thick wedges. Insert 1 wooden pick horizontally through each wedge (to keep it intact while grilling). Whisk together remaining tablespoon vinegar and 1 1/2 tablespoons oil and salt and pepper to taste in a bowl and add onions, tossing gently to coat.
• To cook steak using a charcoal grill:
• Open vents on bottom of grill. Light a large chimney starter of charcoal (80 to 100 briquettes) and pour lit charcoal onto bottom rack, leaving about one quarter of bottom rack free of charcoal and banking remaining coals across rest of bottom rack so that coals are about 3 times higher on opposite side. Charcoal fire is medium-hot when you can hold your hand 5 inches above thickest layer of coals for 3 to 4 seconds. 3Sear steak on lightly oiled grill rack over thickest layer of coals, uncovered, 1 minute on each side, then move steak to area over fewer coals and grill, uncovered, turning occasionally and moving to coolest area of grill if browning too quickly, until thermometer inserted horizontally 2 inches into meat registers 120°F, 10 to 12 minutes. Transfer to a plate and let stand 10 minutes (steak will continue to cook, reaching medium-rare).
• To cook steak using a gas grill:
• Preheat all burners on high, covered, 10 minutes.
• Sear steak on lightly oiled grill rack, uncovered, 1 minute on each side, then reduce heat to moderate. Grill steak, covered, turning occasionally, until thermometer inserted horizontally 2 inches into meat registers 120°F, 10 to 12 minutes. Transfer to a plate and let stand 10 minutes (steak will continue to cook, reaching medium-rare).
• To grill onions by either method:
• While steak is standing, grill onions (covered only if using a gas grill) over moderate heat, turning over once, until tender, about 6 minutes.
• Serve onions with steak; cut steak crosswise into thin slices, holding knife at a 45-degree angle.

GRILLED RED ONIONS WITH BALSAMIC VINEGAR AND ROSEMARY

Steps:

• Prepare grill.
• In a very small saucepan heat rosemary and vinegar over low heat until hot (do not let boil). Remove pan from heat and let mixture stand, covered, 20 minutes.
• In a metal measure heat oil over low heat until warm. (Heating thins oil, making it easier to brush sparingly over onions.) Arrange onion slices in one layer on trays, keeping slices intact, and brush both sides of each slice lightly with oil. Season onions with salt and pepper and grill in batches on a lightly oiled rack set 5 to 6 inches over glowing coals 4 to 6 minutes on each side, or until lightly charred and softened. Transfer onions as grilled to a large bowl, separating rings, and toss with vinegar mixture, parsley, and salt and pepper to taste.
• Serve onions warm or at room temperature.

GRILLED RED ONIONS WITH BALSAMIC VINEGAR AND ROSEMARY

Steps:

• Prepare outdoor or indoor grill.
• In a very small saucepan heat rosemary and vinegar over low heat until hot, but not boiling. Remove pan from heat and cover. Let stand for 20 minutes so that the vinegar becomes infused with the rosemary.
• In a metal measuring cup heat oil over low heat or microwave until warm. (Heating thins oil, making it easier to brush sparingly over onions.) If you are using an indoor grill, place slices on the grill. For an outdoor grill, use a grilling basket to keep onion slices from falling through. If you don't have a basket, place a soaked bamboo skewer through the rings parallel to the cuts so that they do not tumble through the grill. Brush both sides of each slice lightly with oil. Season onions with salt and pepper and grill 4 to 6 minutes on each side, or until lightly charred and softened.
• Transfer onions as grilled to a large bowl, separating rings, and toss with vinegar mixture, parsley, and salt and pepper to taste.
