Quick Grilled Vegetable Flatbread

If you ask me, grilled vegetables belong on flatbread.

This simple summer recipe turns smoky zucchini, asparagus, corn, and red onion into a casual dinner that everyone will want seconds of. The vegetables get kissed by the grill and then piled onto warm flatbread.

A bright herb sauce made with parsley, basil, and chives gets drizzled over everything, along with creamy ricotta cheese. The lemon juice and garlic in the sauce balance out the smoky char from the grill.

It’s a no-fuss meal that works great for busy weeknights or backyard gatherings when the weather is warm.

What Kind of Flatbread Should I Use?

You’ve got plenty of options when it comes to choosing flatbread for this recipe. Store-bought naan works great and comes in different sizes, or you could grab some pita bread if that’s what you have on hand. Greek-style flatbreads are another solid choice, and they tend to hold up well on the grill without getting too crispy. If you want to go the homemade route, that’s awesome too, but store-bought will save you time and still taste delicious. Just make sure whatever flatbread you choose is sturdy enough to support all those grilled veggies without falling apart.

Options for Substitutions

This flatbread recipe is pretty forgiving, so feel free to make these swaps based on what you have:

• Flatbreads: Store-bought flatbreads work great, but you can also use naan, pita bread, or even pizza dough if that’s what you have on hand. Just adjust your grilling time accordingly.
• Grilled vegetables: The vegetable mix is totally flexible. Swap in bell peppers, eggplant, cherry tomatoes, or mushrooms based on what’s in season or what you prefer. Just keep the slicing thickness similar for even cooking.
• Ricotta cheese: If you’re not a ricotta fan, try goat cheese, cream cheese, or even hummus as your base spread. Each will give you a different flavor profile but still taste great.
• Fresh herbs: Don’t have all three herbs? Use what you’ve got – even just parsley and basil will work fine. You can also substitute with 2-3 tablespoons of dried Italian seasoning, though fresh herbs do give better flavor here.
• Parmesan cheese: Pecorino Romano or any hard Italian cheese will work as a substitute. In a pinch, even shredded mozzarella can work, though it won’t have that same sharp, salty kick.
• Fresh corn: Frozen or canned corn (drained well) can replace fresh corn. If using frozen, thaw it first and pat dry before grilling.

Watch Out for These Mistakes While Grilling

The biggest mistake when grilling vegetables is cutting them too thin, which causes them to fall through the grates or turn mushy – stick to that ⅓-inch thickness for zucchini and onions so they hold their shape and develop nice grill marks.

Another common error is overcrowding the grill, which creates steam instead of that smoky char you want, so work in batches if needed and give each vegetable some breathing room.

Don’t skip oiling your grill grates before adding the flatbreads, as they’ll stick and tear when you try to flip them, and keep a close eye on them since they can go from perfectly toasted to burnt in seconds.

For the best flavor, make sure your vegetables are actually tender before taking them off the grill – undercooked asparagus and zucchini won’t have that sweet, caramelized taste that makes this flatbread special.

What to Serve With Grilled Vegetable Flatbread?

This flatbread is pretty filling on its own, but I love serving it alongside a simple arugula salad tossed with olive oil and a squeeze of lemon to keep things fresh and light. If you’re feeding a crowd, cut the flatbreads into smaller pieces and serve them as an appetizer with some marinated olives and a cheese board. A cold glass of white wine or sparkling water with lemon makes a great pairing for a casual summer dinner on the patio. You could also serve it with a bowl of minestrone soup if you want something more substantial for cooler evenings.

Storage Instructions

Store: This flatbread is best enjoyed fresh off the grill, but you can store leftovers in an airtight container in the fridge for up to 2 days. Keep the grilled veggies and flatbread separate if possible so the bread doesn’t get soggy. The herb sauce will keep in a sealed jar in the fridge for about a week.

Prep Ahead: You can grill all the vegetables a day ahead and store them in the fridge, which actually makes assembly super quick when you’re ready to eat. The herb sauce also tastes even better after sitting for a few hours, so feel free to whip that up in advance too.

Serve: If you have leftover assembled flatbread, warm it up in a 350°F oven for about 5-7 minutes to crisp up the bread again. You can also eat it cold as a quick lunch, though it won’t have quite the same appeal as when it’s warm and toasty.

• Calories: 2100-2300

Ingredients

For the pesto:

• 1.5 cups parsley
• 1/2 cup basil
• 1/4 cup chives
• 1/4 cup parmesan (I use Sartori for a nutty finish)
• 2 tsp garlic
• 1 tbsp lemon zest
• 2.5 tbsp lemon juice
• 1/3 cup olive oil (I prefer Lucini Premium Select for dressings)
• 1/4 tsp red pepper flakes

For the grilled vegetables:

• 2 medium zucchini (cut into 1/2-inch thick planks)
• 10 oz asparagus (tough ends trimmed)
• 1 1/4 tsp salt
• 3/4 tsp cracked black pepper
• 1/4 cup olive oil
• 1 large red onion (sliced into 1/2-inch thick rings)
• 2 ears fresh corn

For assembly:

• 4 flatbreads (Stonefire brand is my favorite for grilling)
• 1 1/4 cups whole milk ricotta
• 1 tbsp vegetable oil
• 1 lemon, cut into wedges for serving

Step 1: Make the Herb Pesto Base

• 1.5 cups parsley
• 1/2 cup basil
• 1/4 cup chives
• 1/4 cup parmesan
• 2 tsp garlic
• 1 tbsp lemon zest
• 2.5 tbsp lemon juice
• 1/3 cup olive oil
• 1/4 tsp red pepper flakes

Combine the parsley, basil, chives, grated Parmesan, minced garlic, lemon zest, and lemon juice in a food processor and blend until you have a coarse paste.

Slowly drizzle in the 1/3 cup olive oil while pulsing until the pesto reaches a spreadable consistency—you want some texture, not a completely smooth puree.

Stir in the red pepper flakes and set aside.

I find that making the pesto while the grill heats means it has time to marry the flavors.

Step 2: Prepare and Season the Vegetables

• 2 medium zucchini
• 10 oz asparagus
• 1 large red onion
• 2 ears fresh corn
• 1/4 cup olive oil
• 1 1/4 tsp salt
• 3/4 tsp cracked black pepper

While the pesto sets, prepare your vegetables: cut the zucchini into 1/2-inch thick planks, trim the tough woody ends from the asparagus, slice the red onion into 1/2-inch rings (keep the rings intact with toothpicks if they fall apart), and prepare the corn ears by removing the husks and silk.

Place all vegetables in a large bowl, drizzle with the 1/4 cup olive oil, and season generously with the salt and cracked black pepper.

Toss gently to coat everything evenly.

Step 3: Heat the Grill and Cook the Vegetables

• seasoned vegetables from Step 2

Preheat your grill to 375°F.

Once it reaches temperature, begin grilling the vegetables in batches, starting with the corn and asparagus (which cook fastest at about 5-8 minutes), followed by the zucchini and onion rings (10-15 minutes each).

Work in batches so you don’t overcrowd the grill, and arrange vegetables in a single layer.

You’re looking for light char marks and tender flesh—the vegetables should have some give when pierced with a fork.

As each batch finishes, move it to a clean plate and keep it warm.

Step 4: Grill the Flatbreads Until Charred

• 4 flatbreads
• 1 tbsp vegetable oil

Brush both sides of each flatbread lightly with the vegetable oil—this prevents sticking and creates a nice crust.

Place them directly on the grill and cook for 1-2 minutes per side until you see light char marks and the bread is warm and slightly crispy.

I like to keep the flatbreads on the edge of the grill while the vegetables finish cooking so they stay warm without drying out.

Step 5: Finish the Corn and Assemble the Flatbreads

• herb pesto from Step 1
• grilled vegetables from Step 3
• 2 ears fresh corn
• 1 1/4 cups whole milk ricotta

While the flatbreads are warm, cut the corn kernels from the cob by standing each ear upright and running a sharp knife down the sides.

Spread a generous layer of the herb pesto from Step 1 onto each warm flatbread, leaving a small border.

Arrange the grilled vegetables on top in any pattern you like—distribute the corn kernels, zucchini planks, asparagus spears, and onion rings across each flatbread.

Top each one with a dollop of ricotta, letting it fall naturally across the vegetables for a rustic presentation.

Step 6: Cut and Serve

• assembled flatbreads from Step 5
• 1 lemon, cut into wedges for serving

Slice each flatbread into thirds or quarters, depending on your preference, and transfer to a serving platter.

Serve immediately while everything is still warm, with fresh lemon wedges on the side for guests to squeeze over their portions for a bright finish.
