Step‑by‑Step Instructions for Perfectly Grilled Onions: Wedges, Rings, & Whole in Foil

Step 1: Prepare the Onions
Start by peeling and trimming your medium yellow and red onions. For wedges, slice each yellow onion into 8 wedges while keeping the base intact to hold them together. For rings, cut the medium red onions into ½ inch thick slices. This preparation will ensure your grilled onions are perfectly shaped and ready for the grill.

Step 2: Set Up the Grill
Preheat your grill to medium-high heat for charcoal or medium heat for gas. Make sure to create an indirect heat zone by moving the coals to one side or turning off a burner, which will help cook the onions evenly without burning. This setup is essential for achieving tender, smoky grilled onions that are cooked to perfection.

Step 3: Grill the Onion Wedges
Brush the onion wedges with olive oil and sprinkle generously with sea salt and any fresh herbs you prefer. Place the seasoned wedges on the indirect heat zone of the grill. Close the lid and allow them to grill for about 10 minutes per side. Look for a nice char on the edges and a softened center, indicating they’re ready to be turned for even grilling.

Step 4: Grill the Onion Rings
For the onion rings, arrange them on a baking sheet. In a small bowl, mix olive oil and balsamic vinegar, then brush this mixture onto the rings. Place the rings on the grill over indirect heat. Grill for approximately 8-10 minutes per side, or until they’re golden caramelized and soft. Keep an eye on them to prevent burning and ensure they achieve that sweet taste.

Step 5: Grill the Whole Onions in Foil
Take your whole onions and wrap them tightly in foil with a drizzle of BBQ sauce and a sprinkle of freshly chopped parsley. This technique helps to lock in the flavors and steam the onions. Grill the wrapped onions over indirect heat for 30-40 minutes. You’ll know they’re done when they feel soft all the way through; a great method for enjoying perfectly grilled onions.

Step 6: Serve and Enjoy
Once all your grilled onions are cooked to your liking, carefully remove them from the grill. You can drizzle extra olive oil or your favorite dressing over them if desired. These beautifully grilled onions make a fantastic addition to any meal, whether served solo or as toppings for burgers or salads.

How to Store and Freeze Grilled Onions

Freezer: For longer storage, freeze grilled onions in a freezer-safe bag for up to 3 months. Spread them out flat before sealing to save space.

Reheating: Reheat grilled onions on the grill or in a skillet over medium heat, adding a splash of olive oil to revive their smoky flavor and tenderness.

Tips for the Best Grilled Onions

Grill Temperature: Ensure your grill is preheated to medium-high heat. A consistent temperature promotes even cooking, avoiding burnt edges but softening centers for perfectly grilled onions.
Use a Grill Mat: For onion wedges, a grill mat can help keep the wedges intact and prevent them from slipping through grates, making flipping much easier and reducing waste.
Keep a Close Eye: When grilling onion rings, they can caramelize quickly. Stay attentive and check for a golden-brown color to avoid burning these delicious treats.
Herb Experimentation: Feel free to experiment with different herbs! Mixing olive oil with various herbs can lend unique flavors to your grilled onions, enhancing the natural sweetness.
Storage Wise: If you have leftovers, store grilled onions in an airtight container in the fridge for up to 3-5 days. They can be easily reheated in a skillet or on the grill, preserving their smoky goodness.

Grilled Onions: Wedges, Rings, & Whole in Foil Recipe FAQs

How do I select the right onions for grilling?
Absolutely! For the best flavor, choose medium yellow onions for wedges since they caramelize beautifully and become sweet when grilled. Ensure they are firm and free from dark spots or soft spots, indicating freshness.

How should I store leftover grilled onions?
After grilling, let them cool completely then place them in an airtight container. They can be stored in the fridge for up to 3-5 days. I often reheat them on the grill or in a skillet, drizzling a little olive oil to bring back their original smoky goodness.

Can I freeze grilled onions for later use?
Yes, you can! To freeze grilled onions, first cool them completely, then spread them out on a baking sheet in a single layer and freeze until solid. Once frozen, transfer them to a freezer-safe zip-top bag. They’ll stay good for up to 3 months. To use, simply reheat directly from frozen, or thaw overnight in the fridge.

What if my onions are burning on the grill?
Very good question! If you notice your onions are burning, it may be due to too high heat or if they’re too thinly cut. Be sure the grill is set to medium heat and try moving them to the indirect heat zone. For wedges, a grill mat can help keep them from slipping through the grates.

Are grilled onions safe for pets?
Unfortunately, onions are toxic to pets, particularly dogs. Even small amounts can cause anemia. It's best to enjoy your grilled onions while keeping them away from your furry friends.

Can I use other types of onions for grilling?
Absolutely! Red onions work wonderfully for rings, lending a sweeter taste, while white onions are also a good option for grilling due to their mild flavor. Just keep in mind that the grilling time may vary slightly depending on the type of onion used.
