Ingredients
For the Vegetables:
- 2 medium zucchini, cut into 1-inch rounds
- 2 bell peppers (red and yellow), cut into 1-inch squares
- 1 large red onion, cut into 1-inch chunks
- 8 oz mushrooms, stems trimmed (button or cremini)
- 1 pint cherry tomatoes
- 1 medium eggplant, cut into 1-inch cubes
- 2 yellow squash, cut into 1-inch rounds
For the Mediterranean Marinade:
- 1/3 cup extra virgin olive oil
- 3 tablespoons fresh lemon juice
- 3 cloves garlic, minced
- 2 tablespoons fresh oregano, chopped
- 1 tablespoon fresh thyme, chopped
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon red pepper flakes
For the Herb Butter Finish:
- 4 tablespoons butter, softened
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon fresh basil, chopped
- 1 clove garlic, minced
- Salt and pepper to taste
Preparing the Vegetables
Begin by washing all vegetables thoroughly and patting them completely dry. Cut all vegetables into uniform 1-inch pieces to ensure even cooking. This consistency is crucial for having all vegetables finish cooking at the same time.
For the eggplant, sprinkle the cut pieces with salt and let them sit in a colander for 20 minutes to draw out bitterness. Rinse thoroughly and pat dry before proceeding. This step prevents the eggplant from becoming soggy during grilling.
Creating the Perfect Marinade
In a large mixing bowl, whisk together the olive oil, fresh lemon juice, minced garlic, oregano, thyme, salt, black pepper, and red pepper flakes until well combined. The marinade should be aromatic and well-emulsified.
Taste the marinade and adjust seasoning as needed. It should be bright and flavorful since it will be the primary seasoning for the vegetables. The acid from the lemon juice will help tenderize the vegetables while the herbs provide fresh, Mediterranean flavors.
Marinating the Vegetables
Add all the prepared vegetables to the marinade, tossing gently but thoroughly to ensure every piece is well coated. Use your hands to distribute the marinade evenly, making sure the garlic and herbs reach all the vegetables.
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, or up to 2 hours for deeper flavor penetration. Turn the vegetables occasionally during marinating to ensure even flavor distribution.
Assembling the Skewers
Soak wooden skewers in water for at least 30 minutes before threading to prevent burning. Thread the marinated vegetables onto skewers, alternating colors and types for visual appeal and balanced cooking.
Leave small gaps between pieces to allow for even heat circulation and proper cooking. A typical skewer might include: bell pepper, zucchini, mushroom, red onion, cherry tomato, eggplant, and yellow squash in that order.
Preparing the Grill
Preheat your grill to medium-high heat, around 400-450°F. Clean the grill grates thoroughly and oil them well to prevent sticking. For gas grills, preheat with the lid closed. For charcoal, arrange coals for medium-high direct heat.
Create two heat zones if possible – one direct high heat area and one slightly cooler area. This gives you flexibility to move skewers if they’re cooking too quickly or need gentler heat.
Grilling Technique
Place the vegetable skewers on the grill and cook for 12-15 minutes total, turning every 3-4 minutes to ensure even browning on all sides. Different vegetables cook at different rates, so watch carefully and adjust positioning as needed.
The vegetables are done when they’re tender when pierced with a fork and have beautiful grill marks. Cherry tomatoes should be slightly charred but still holding their shape, while peppers and onions should be caramelized and sweet.
Making the Herb Butter
While the skewers are grilling, prepare the herb butter by mixing the softened butter with fresh parsley, basil, minced garlic, salt, and pepper. This compound butter adds richness and fresh herb flavor to the finished skewers.
The herb butter can be made ahead and stored in the refrigerator, then brought to room temperature before serving so it melts beautifully over the hot vegetables.
Finishing and Serving
Remove the skewers from the grill and immediately brush or dot with the herb butter while they’re still hot. The butter will melt and create a glossy, flavorful coating that enhances both taste and presentation.
Arrange the skewers on a large serving platter and garnish with additional fresh herbs if desired. Serve immediately while hot for the best flavor and texture contrast between the caramelized exterior and tender interior.
Serving Suggestions and Variations
These vegetable skewers pair beautifully with grilled bread, rice pilaf, quinoa salad, or as part of a larger barbecue spread. They also work well over pasta or as a topping for pizza.
For different flavor profiles, try Asian-inspired marinades with soy sauce, ginger, and sesame oil, or Mexican variations with lime juice, cumin, and chili powder. Indian spice blends with curry powder and yogurt create another delicious option.
Storage and Make-Ahead Tips
The vegetables can be marinated up to 4 hours ahead, and the skewers can be assembled earlier in the day and refrigerated until ready to grill. Cooked skewers keep well in the refrigerator for 2-3 days and can be reheated gently in the oven.
For meal prep, remove the vegetables from the skewers after cooking and store in containers. They make excellent additions to grain bowls, salads, or pasta dishes throughout the week.
