This method yields an incredibly flavorful, caramelized onion that’s perfect for topping burgers, sandwiches, salads, or simply enjoying as a side dish.
The Allure of Grilled Onions
Grilled onions are a culinary chameleon. Their sweet, smoky flavor adds depth and complexity to any dish. The caramelization process intensifies their natural sweetness, creating a rich, almost savory flavor profile. And the best part? They’re incredibly easy to make!
The Essential Tools for Grilled Onion Success
Before we dive into the grilling process, let’s gather our essentials:
- Onions: Choose firm, medium-sized onions like yellow, white, or red. Avoid onions with soft spots or blemishes.
- Aluminum Foil: Heavy-duty foil is recommended for even heat distribution and to prevent tearing.
- Olive Oil: A drizzle of olive oil will help the onions caramelize and prevent them from sticking to the foil.
- Salt and Pepper: These seasonings are essential for enhancing the onion’s natural flavors.
- Optional Additions: Get creative with herbs like rosemary, thyme, or oregano, or add a touch of sweetness with honey or maple syrup.
Prep Work: Getting Your Onions Ready
1. Cleaning and Cutting: Wash your onions thoroughly and trim off the root end. Slice the onion into ½-inch thick slices, leaving the root end intact to help hold the slices together.
2. Seasoning and Oil: Place the onion slices in a bowl and drizzle with olive oil. Season generously with salt and pepper, and add any desired herbs or spices.
The Grilling Process: Bringing Out the Flavor
1. Foil Preparation: Tear a large sheet of aluminum foil, about 12 inches square. Fold the foil in half to create a double layer for added durability.
2. Onion Placement: Place the seasoned onion slices in the center of the foil. Fold the sides of the foil over the onions, creating a tightly sealed packet.
3. Grilling Time: Preheat your grill to medium heat. Place the foil packet on the grill and cook for 15-20 minutes, or until the onions are soft and caramelized.
4. Checking Doneness: Carefully lift the packet from the grill and open it slightly to check the onions. They should be soft and translucent, with a deep brown color. If they’re not quite done, close the packet and return it to the grill for a few more minutes.
Serving Up Your Grilled Onion Delights
Once the onions are cooked to perfection, carefully transfer the foil packet to a cutting board. Open the packet and let the onions rest for a few minutes before serving. Enjoy them as a side dish, or use them to top burgers, sandwiches, or salads.
Variations for Deliciousness
- Sweet and Spicy: Add a pinch of cayenne pepper or chili flakes to the foil packet for a spicy kick.
- Herbed Delight: Experiment with different herbs like rosemary, thyme, or oregano for a fragrant and flavorful twist.
- Honey Glazed: Drizzle a tablespoon of honey over the onions before sealing the foil packet for a sweet and savory treat.
Beyond the Grill: Other Ways to Use Grilled Onions
Grilled onions aren’t just for grilling season. You can easily prepare them in the oven or on the stovetop.
- Oven-Roasted: Preheat your oven to 375°F. Place the foil packet on a baking sheet and roast for 15-20 minutes, or until the onions are soft and caramelized.
- Stovetop Caramelization: Heat a skillet over medium heat and add a drizzle of olive oil. Add the onion slices and cook for 15-20 minutes, stirring occasionally, until they are softened and caramelized.
