Grilled Veggies: Foil Pan & Olive Oil Magic

Grilling vegetables in a foil pan with olive oil is a great way to cook veggies without making a mess of your grill. It's also a convenient way to prepare a large number of vegetables at once. The foil creates a sealed environment that locks in moisture and flavour, resulting in a tender, juicy, and well-rounded taste. It also prevents the vegetables from sticking to or falling through the grill.

How to prepare the vegetables for grilling

Grilling vegetables in a foil pan with olive oil is a great way to retain their natural flavours and juices. The sealed environment created by the foil helps lock in moisture and flavour, marinating the vegetables in their natural juices and seasonings. This method also prevents the vegetables from sticking to or falling through the grates, and simplifies the clean-up process.

• Select the Right Foil: Choose heavy-duty or non-stick foil for grilling. Heavy-duty foil is thick and durable, withstanding high grilling heat, while non-stick foil has a special coating that prevents sticking.
• Prepare the Vegetables: Wash and cut the vegetables into similar sizes and thicknesses. This ensures even cooking and prevents overcooking or undercooking. You can use a variety of vegetables such as zucchini, bell peppers, onions, asparagus, mushrooms, carrots, potatoes, eggplant, corn, and more.
• Create the Foil Packets: Tear off a sheet of foil large enough to wrap your vegetables with extra room for steam circulation. Add seasonings like minced garlic, garlic powder, lemon juice, or soy sauce, and then drizzle olive oil over the vegetables and foil. Place the vegetables on the foil and create a packet by folding and sealing the foil tightly.
• Preheat the Grill: Preheat your grill to the appropriate temperature based on the type of vegetables you are cooking. The grill temperature will vary depending on whether you are cooking at high heat (400-450°F), medium heat (350-400°F), or low heat (300-350°F).
• Place the Foil Packets on the Grill: Place the foil packets on the grill grate with the folded side facing up to prevent potential leaks. Grill the vegetables with the lid closed, and flip the packets halfway through for even cooking.
• Check for Doneness: Carefully open the top of the packet to check if the vegetables are cooked to your desired tenderness. Reseal and grill for a few more minutes if needed.
• Serve: Allow the foil packets to cool before handling. Carefully open the packets, being cautious of escaping steam. Transfer the grilled vegetables to a serving dish and garnish with fresh herbs, lemon or lime juice, cheese, nuts, or seeds.

How to make the foil packets

Selecting the Right Foil

Use heavy-duty or non-stick foil for grilling vegetables. Heavy-duty foil is thick and durable and can withstand high grilling heat, while non-stick foil has a special coating that prevents sticking.

Preparing the Vegetables

Cut the vegetables into similar sizes and thicknesses to prevent overcooking or undercooking. You can cut them into circles, coin-shaped pieces, or long, flat horizontal pieces.

Making the Foil Packets

Tear off a sheet of foil large enough to wrap your vegetables with room for steam circulation. Add seasonings like minced garlic, garlic powder, lemon juice, or soy sauce, and then place the vegetables in the centre of the foil.

To make an envelope fold, fold half of the foil over the vegetables and align and fold the side edges towards the centre, making small overlapping folds. Repeat until the packet is tightly sealed.

To make a packet roll, fold the foil halfway over and then, starting at one end, tightly roll it toward the vegetables to ensure a tight seal.

Grilling the Vegetables

Preheat the grill to ensure optimal cooking results and prevent sticking. The right temperature depends on the vegetables and desired results:

• High heat (400-450°F) cooks vegetables quickly and chars the exterior while retaining a tender interior. It suits bell peppers, asparagus, summer squash, and zucchini.
• Medium heat (350-400°F) is better for denser vegetables like potatoes and carrots, which take longer to cook but retain more moisture.
• Low heat (300-350°F) is best for delicate vegetables like mushrooms, broccoli, and Brussels sprouts.

Place the foil packets on the grill grate with the folded side facing up to prevent leaks. Grill the vegetables with the lid closed and flip the packets halfway through for even cooking. Check for doneness by carefully opening the top of the packet.

How to grill the vegetables in the foil

Grilling vegetables in foil is a great way to cook veggies that are small and delicate, such as cherry tomatoes, oyster mushrooms, or corn, as it prevents them from falling through the grill grates or sticking to them. It also helps retain their natural juices and flavours, and simplifies the clean-up process.

How to Grill Vegetables in Foil:

Selecting the Right Foil

Go for heavy-duty or non-stick foil. Heavy-duty foil is thick and durable and can withstand high grilling heat, while non-stick foil has a special coating that prevents sticking.

Preparing the Vegetables

• Cut your vegetables into similar sizes and thicknesses to prevent overcooking or undercooking.
• Vegetables with a higher water content, such as cucumbers, celery, and most leafy greens (except Romaine lettuce) are not ideal for grilling.
• Marinate the vegetables in a zip-lock bag with olive oil, salt, and pepper, or brush them lightly with cooking oil before placing them on the grill.
• For softer vegetables like zucchini and squash, cut them into longer, flat horizontal pieces if grilling directly on the grill, or into circles if using a grill pan.
• For denser vegetables like peppers, cut them into quarters if grilling directly, or into coin-shaped pieces if using a grill pan.

Creating the Foil Packets

• Tear off a sheet of foil large enough to wrap your vegetables with room for steam circulation and extra room for folding and sealing.
• Add seasonings like minced garlic, garlic powder, lemon juice, or soy sauce, depending on your preference.
• Place the vegetables in the centre of the foil and fold it over to create a pocket.
• Align the side edges and fold them towards the centre, making small overlapping folds until the packet is tightly sealed.
• Alternatively, fold the foil halfway over and then, starting at one end, tightly roll it toward the vegetables to ensure a tight seal.
• Lightly brush or spray the foil with oil to prevent sticking.

Grilling the Vegetables

• Preheat the grill to ensure optimal cooking results and to prevent the vegetables from sticking.
• The grill temperature will depend on the type of vegetables and the desired results:
• High heat (400-450°F) for bell peppers, asparagus, summer squash, and zucchini.
• Medium heat (350-400°F) for potatoes, carrots, and onions.
• Low heat (300-350°F) for mushrooms, broccoli, and Brussels sprouts.
• Place the foil packets on the grill grate with the folded side facing up to prevent leaks.
• Grill the vegetables with the lid closed and flip the packets halfway through for even cooking.
• Check for doneness by carefully opening the top of the packet. Reseal and leave on the grill for a few more minutes if needed.
• Grilling times will vary depending on the type of vegetable, their size, and the desired tenderness.

Tips for Serving:

• Allow the foil packets to cool before opening to prevent accidental burns.
• Carefully unfold the packets or cut an "X" at the top to allow steam to escape.
• Transfer the grilled vegetables to a serving dish using a spatula or tongs, being careful not to break or smash them.
• Garnish with fresh herbs, lemon or lime juice, cheese, toasted nuts, or seeds for added flavour and visual appeal.

How long to grill the vegetables for

The time it takes to grill vegetables in a foil pan with olive oil depends on the type of vegetables, the size, and the desired level of tenderness.

Small and tender vegetables like cherry tomatoes, Brussels sprouts, and mushrooms will take 10-15 minutes to cook. Medium-sized vegetables like zucchini and bell pepper strips typically take 15-20 minutes to cook. In comparison, large and dense vegetables like potatoes and carrots take about 20-30 minutes to get fork-tender.

When grilling vegetables in a foil pan with olive oil, it is important to preheat the grill to ensure even cooking. The grill temperature can be adjusted depending on the type of vegetable and the desired result. High heat, or 400-450°F, cooks vegetables quickly while retaining a tender interior. Medium heat, or 350-400°F, results in a longer cook time but retains moisture. Low heat, or 300-350°F, is best for delicate vegetables and requires a longer cooking time.

Additionally, it is recommended to cut the vegetables into similar sizes and thicknesses to ensure even cooking and prevent overcooking or undercooking.
