The addition of balsamic vinegar is optional but adds an extra layer of richness and complexity. Grilled onions are versatile and can be used as a topping, in wraps, or served as a side dish.
What You’ll Need for Best Ever Grilled Onions:
Ingredients:
- 2 large onions (Sweet onions like Vidalia or Walla Walla are ideal for this recipe, as their sweetness really shines when grilled)
- 2 tablespoons olive oil or melted butter (both options work well; olive oil is lighter, while butter adds richness)
- 1 tablespoon balsamic vinegar (optional, for an extra touch of sweetness and depth)
- 1/2 teaspoon salt (to season and bring out the flavor)
- 1/4 teaspoon black pepper (for a subtle kick)
- 1/4 teaspoon garlic powder (optional, but it adds a lovely garlicky undertone)
- Fresh herbs like thyme or rosemary (optional, for added flavor and fragrance)
How to Make Best Ever Grilled Onions:
Step 1: Prepare the Onions
- Peel the onions and cut them into thick slices, about 1/2 inch thick. If you prefer onion rings, you can separate the slices into individual rings. For larger slices, you’ll want to keep the rings intact so they don’t fall apart on the grill.
Step 2: Season the Onions
- In a small bowl, whisk together the olive oil or melted butter, balsamic vinegar (if using), salt, pepper, and garlic powder (if using). Brush this mixture generously on both sides of the onion slices. You can also sprinkle a little fresh thyme or rosemary on top for added flavor.
Step 3: Preheat the Grill
- Preheat your grill to medium heat (about 350-400°F). If you’re using a grill pan on the stovetop, preheat it over medium-high heat. You can also use a cast-iron skillet if you don’t have a grill.
Step 4: Grill the Onions
- Place the seasoned onions directly on the grill. Cook for about 4-5 minutes on each side, flipping carefully so the onions don’t break apart. You want the onions to have nice grill marks and become tender but still hold their shape. Grill until the onions are deeply caramelized and slightly softened. The cooking time may vary depending on the thickness of the slices and your grill’s heat.
Step 5: Serve and Enjoy
- Remove the onions from the grill and serve them immediately as a side dish, topping for burgers, or inside sandwiches. For extra flavor, garnish with fresh herbs like thyme or rosemary.
Tips for Success:
- Choose Sweet Onions: Vidalia, Walla Walla, or other sweet onions are perfect for grilling because they caramelize beautifully. Regular yellow onions are also good but will have a sharper flavor.
- Don’t Overcrowd the Grill: Make sure there’s enough space between the onion slices so they grill evenly and don’t steam.
- Use a Grill Basket or Foil for Smaller Pieces: If you’re making onion rings or smaller pieces, use a grill basket or place the onions on foil to avoid them falling through the grates.
- Adjust for Your Preference: If you want your onions to be sweeter, you can add a little more balsamic vinegar or a sprinkle of brown sugar before grilling.
- Control the Heat: Avoid cooking on high heat, as it can burn the onions before they have a chance to soften and caramelize. Medium heat allows the onions to cook evenly and develop the right balance of sweetness and smokiness.
