What You’ll Need?

- Extra-virgin olive oil, for drizzling (use a high-quality oil for the best flavor)
- Sea salt and freshly ground black pepper, to taste (adjust according to your preference)
How to Make Grilled Onions?
- Preheat the grill or grill pan to medium heat (around 375°F/190°C).
- In a medium bowl, toss the onion wedges with a drizzle of olive oil, a pinch of sea salt, and a few grinds of black pepper. Ensure the onions are evenly coated.
- Place the onions on the grill and cook for 4 to 5 minutes per side, or until char marks form and the onions are tender but still hold their shape.
- Remove from the grill and serve immediately as a side dish or topping for burgers, steaks, or salads.
Perfect Pairings: Serving Suggestions
Grilled onions are incredibly versatile and can elevate a variety of dishes. Serve them as a flavorful topping for burgers, steaks, or grilled chicken. They also make a delicious addition to salads, tacos, or even as a side dish with roasted vegetables. For a simple yet satisfying meal, pair them with a crusty baguette and a dollop of creamy goat cheese.
Flavor Boost: Sauce and Topping Ideas
Take your grilled onions to the next level with a drizzle of balsamic glaze or a sprinkle of fresh herbs like thyme or parsley. For a tangy twist, try adding a splash of lemon juice or a spoonful of chimichurri sauce. If you’re feeling adventurous, mix in a pinch of smoked paprika or chili flakes for a smoky, spicy kick.
Quick Tips: Time-Saving Hacks
To save time, slice the onions in advance and store them in an airtight container in the fridge until you’re ready to grill. If you’re using a grill pan, make sure it’s well-heated before adding the onions to ensure even cooking and those perfect char marks. For a hands-off approach, toss the onions in a grill basket to prevent them from falling through the grates.
Leftover Love: Storage and Reheating
Store any leftover grilled onions in an airtight container in the fridge for up to 3 days. To reheat, simply warm them in a skillet over medium heat or pop them in the microwave for 30-60 seconds. They’re perfect for adding to omelets, sandwiches, or pasta dishes throughout the week.
Mix It Up: Recipe Variations
Experiment with different types of onions, such as sweet Vidalia or yellow onions, for a unique flavor profile. You can also add other vegetables like bell peppers or zucchini to the mix for a colorful grilled medley. For a richer taste, toss the onions with a bit of melted butter or garlic-infused olive oil before grilling.
