Barbecued Grilled Vegetables Recipe (Olive Oil Marinade)
This barbecued grilled vegetables recipe shows you how to toss zucchini, eggplant, and sweet onion with a quick olive oil, garlic, and oregano marinade, then grill them over high heat. Slice everything evenly so the veggies brown fast on the outside while staying tender-crisp inside. Ingredients and how to make it are right below.
Ingredients
Marinade
Step-by-Step Method
Preheat the grill
Heat your barbecue grill to medium-high. Lightly oil the grates so the vegetables release easily.
Mix the marinade
In a bowl, whisk together the broth, olive oil, garlic, dried oregano, and black pepper until combined.
Prep the vegetables
Slice the zucchini and eggplant into even planks or thick rounds. Thinly slice the sweet onion into strips.
Coat with marinade
Add the vegetables to a large bowl and toss with the marinade. Aim for a light, even coating rather than pooling liquid.
Grill until charred-tender
Arrange the vegetables in a single layer on the grill. Cook 3–5 minutes per side, turning to get grill marks, until tender but not falling apart.
Rest and serve
Let the vegetables rest for 2 minutes. Serve warm or at room temperature; add a small drizzle of olive oil if you like.
