Ingredients
Vegetables
2 cups broccoli florets
2 cups cauliflower florets
2 cups carrots, sliced
1 red bell pepper, chopped
1 yellow bell pepper, chopped
Oil & Aromatics
¼ cup olive oil
4 cloves garlic, minced
Herbs & Seasonings
1 tsp dried oregano
1 tsp dried thyme
Salt and black pepper, to taste
Instructions
Prepare the Vegetables
Wash and dry all the vegetables thoroughly. Cut the broccoli and cauliflower into similar-sized florets so they cook evenly.
Slice the carrots into relatively thin, even pieces. Chop the red and yellow bell peppers into medium-sized pieces.
Try to keep the vegetable pieces fairly uniform. Larger pieces will take longer to cook, while very small pieces may become too soft before the other vegetables are ready.
Make the Herb Garlic Oil
In a large bowl, combine the olive oil, minced garlic, dried oregano, dried thyme, salt, and black pepper.
Whisk or stir well to distribute the garlic and herbs throughout the oil.
Add the prepared broccoli, cauliflower, carrots, red bell pepper, and yellow bell pepper to the bowl. Toss thoroughly until all the vegetables are lightly coated with the seasoned olive oil.
Allow the vegetables to sit for about 5 minutes while you prepare the grill.
Preheat the Grill
Preheat the grill to medium-high heat, approximately 400–425°F.
If using a grill basket or grill pan, place it on the grill while it heats. A grill basket is especially helpful for smaller vegetables because it prevents pieces from falling through the grates.
If grilling directly on the grates, make sure they are clean and lightly oiled to help prevent sticking.
Grill the Vegetables
Arrange the vegetables in a single layer in a grill basket or across the grill grates.
Grill for approximately 20–25 minutes, turning or tossing the vegetables every few minutes so they cook evenly.
The vegetables should become tender while developing lightly charred and golden edges. The broccoli and cauliflower should be fork-tender, the carrots should soften, and the bell peppers should become slightly tender with some caramelized edges.
If some vegetables begin browning too quickly, move them to a cooler part of the grill and continue cooking until everything reaches the desired tenderness.
Check for Doneness
Test the thickest carrot pieces and the cauliflower with a fork. They should be tender but should still have enough structure to hold their shape.
If the vegetables need more time, continue grilling for a few additional minutes.
Avoid overcooking them, as the goal is to create vegetables that are tender on the inside while maintaining some texture and grilled character.
Serve
Transfer the grilled vegetables to a serving dish while they are still warm.
Taste and add a little more salt or black pepper if needed.
Serve immediately as a colorful side dish, or allow the vegetables to cool slightly and use them in salads, grain bowls, wraps, or meal-prep containers.
Tips
Dry the Vegetables Well
After washing the vegetables, dry them thoroughly before adding the oil. Excess water can create steam and make it harder for the vegetables to develop beautiful grilled edges.
Cut Vegetables Evenly
Uniform pieces help everything cook at approximately the same rate. Since carrots are naturally denser than bell peppers, slicing them relatively thin helps them finish at the same time.
Do Not Overcrowd the Grill
Arrange the vegetables in a single layer whenever possible. Too many vegetables packed together can trap moisture and reduce browning.
Use a Grill Basket
A grill basket makes this recipe especially easy. It keeps smaller broccoli and cauliflower pieces safely contained while still allowing heat and smoke to reach the vegetables.
Preheat Properly
A fully preheated grill helps the vegetables begin cooking immediately and encourages caramelization. Starting with a cold or barely warm grill can make the vegetables softer rather than nicely grilled.
Turn Frequently
Toss or turn the vegetables every few minutes. This prevents one side from becoming overly charred while allowing multiple surfaces to develop flavorful browned edges.
Watch the Garlic
Fresh minced garlic can burn if exposed directly to very high heat for too long. Tossing it thoroughly with the olive oil and vegetables helps distribute it and reduces the chance of concentrated burning.
Taste Before Serving
Vegetables can vary in sweetness and size, so always taste the finished dish before serving. A final pinch of salt and black pepper can bring all the herb and garlic flavors together.
Variations
Add Lemon Flavor
Finish the grilled vegetables with fresh lemon juice and a little lemon zest just before serving. The bright citrus flavor works especially well with oregano and thyme.
Mediterranean Vegetable Mix
Add sliced zucchini, yellow squash, red onion, or cherry tomatoes to create a larger Mediterranean-style vegetable platter.
Add Parmesan
Sprinkle freshly grated Parmesan over the hot vegetables immediately after grilling. The residual heat will soften the cheese slightly and add a savory finish.
Make It Spicy
Add a pinch of red pepper flakes or cayenne pepper to the olive oil mixture for a little heat.
Fresh Herb Finish
Replace some of the dried herbs with fresh parsley, basil, rosemary, or oregano. Add fresh herbs after grilling for the brightest flavor.
Add Balsamic Flavor
Drizzle a small amount of balsamic glaze over the finished vegetables for a sweet and tangy contrast.
Turn Them Into a Main Dish
Serve the vegetables over cooked quinoa, couscous, rice, or pasta. Add chickpeas, grilled chicken, or white beans for a more substantial meal.
Use as a Meal-Prep Side
Divide the cooled vegetables into individual containers and refrigerate them for easy lunches or dinners throughout the week.
Q&A
Can I roast these vegetables in the oven instead of grilling them?
Yes. Spread the seasoned vegetables on a large baking sheet and roast at about 425°F until tender and lightly browned, turning once during cooking.
Can I prepare the vegetables ahead of time?
Yes. The vegetables can be washed, cut, and seasoned ahead of time. Store them covered in the refrigerator until you are ready to grill.
How do I prevent grilled vegetables from becoming soggy?
Dry the vegetables well, avoid overcrowding the grill, and cook them over properly preheated medium-high heat. These steps encourage browning instead of steaming.
Can I use fresh herbs instead of dried herbs?
Yes. Fresh herbs can be used, although they are best added toward the end of cooking or after grilling to preserve their fresh flavor.
What can I serve with grilled vegetables?
They pair well with grilled chicken, salmon, steak, shrimp, burgers, roasted meats, pasta, rice, couscous, and grain bowls.
How long do leftovers last?
Store the cooked vegetables in an airtight container in the refrigerator and use them within about 3–4 days for the best quality.
Can I eat these vegetables cold?
Yes. They are delicious chilled or at room temperature and work particularly well in salads, wraps, sandwiches, and grain bowls.
Can I use frozen vegetables?
Fresh vegetables are recommended for the best grilled texture. If using frozen vegetables, thaw and drain them thoroughly first because excess moisture can interfere with browning.
