Mouthwatering Grilled Vegetable Tacos

If you ask me, grilled vegetable tacos are one of the best ways to enjoy summer produce.

These smoky tacos are packed with charred bell peppers, zucchini, and corn that get tossed in a simple spice blend before hitting the grill. The vegetables pick up great flavor from the chipotle pepper and cumin.

They’re tucked into warm tortillas and topped with creamy avocado, crumbled Cotija cheese, and fresh cilantro. A squeeze of lime at the end brings everything together.

It’s a satisfying meal that works for busy weeknights, perfect when you want something fresh and filling.

What Kind of Bell Peppers Should I Use?

For grilled vegetable tacos, you can use red, yellow, or orange bell peppers – they all work great and bring a slightly sweet flavor when grilled. I’d skip green bell peppers for this recipe since they can taste a bit bitter compared to their colorful counterparts. If you want the sweetest flavor, go with red peppers, but honestly, you can’t go wrong with any of the sweeter varieties. Feel free to mix and match colors if you have a few on hand – it’ll make your tacos look even more appetizing on the plate.

Options for Substitutions

These tacos are super forgiving when it comes to swapping ingredients:

• Bell peppers: Any color bell pepper works great here – red, yellow, orange, or even green. You can also try poblano peppers for a mild smoky flavor.
• Zucchini: Yellow squash is basically interchangeable with zucchini. You could also use eggplant, but slice it a bit thicker and brush with extra oil since it soaks up more.
• Corn: Fresh corn is ideal, but frozen corn works in a pinch. Just thaw it first and pat it dry before grilling. Canned corn isn’t recommended since it gets too mushy.
• Ground chipotle pepper: If you don’t have chipotle powder, use regular chili powder or smoked paprika. Start with half the amount if using cayenne since it’s spicier.
• Queso fresco or cotija cheese: Feta cheese makes a good substitute with a similar crumbly texture. For a dairy-free option, skip the cheese and add extra avocado or a drizzle of tahini.
• Tortillas: Both corn and flour tortillas work perfectly – it’s really just personal preference. Corn tortillas are more traditional and gluten-free if that matters to you.

Watch Out for These Mistakes While Grilling

The biggest mistake when grilling vegetables is cutting them too small, which causes them to fall through the grates or burn quickly – aim for pieces about 1 to 1.5 inches so they cook evenly and stay put in your grill basket.

Don’t skip preheating your grill basket or foil for at least 5 minutes, as a hot surface helps vegetables get those nice char marks without sticking or steaming instead of grilling.

Another common error is overcrowding the grill basket, which traps steam and leaves you with mushy vegetables rather than the slightly charred, tender result you’re after – cook in batches if needed and give each piece some breathing room.

Finally, resist the urge to constantly stir the vegetables; let them sit undisturbed for 2-3 minutes at a time so they can develop that smoky, caramelized flavor that makes grilled tacos so good.

What to Serve With Grilled Vegetable Tacos?

These tacos are pretty filling on their own, but I love serving them with a side of Mexican rice or cilantro lime rice to round out the meal. Black beans or refried beans make a great addition too, and you can even stuff some right into the tacos if you want extra protein. A simple side salad with lime dressing or some tortilla chips with fresh salsa and guacamole keeps things light and fresh. For drinks, I’d go with a cold Mexican beer, margaritas, or even just some agua fresca to balance out the smoky flavors from the grilled veggies.

Storage Instructions

Store: Keep your grilled veggies in an airtight container in the fridge for up to 4 days. I like to store them separately from the tortillas and toppings so everything stays fresh and the tortillas don’t get soggy.

Freeze: The grilled vegetables freeze really well for up to 3 months. Just let them cool completely first, then pack them in a freezer-safe container or bag. When you’re ready to use them, thaw in the fridge overnight.

Serve: Warm up the veggies in a skillet over medium heat for a few minutes until heated through. You can also microwave them, but the skillet gives them a nice crispy edge again. Heat your tortillas fresh and add the avocado and cheese right before serving for the best flavor.

Ingredients

For the grilled filling:

• 1 large bell pepper (cut into 1-inch squares)
• 1 medium zucchini (sliced into 1/2-inch thick rounds)
• 1 medium red onion (cut into 1-inch wedges)
• 2 ears corn (husks removed)
• 3 tbsp olive oil
• 1 tsp salt
• 1/2 tsp chipotle pepper
• 1 tsp cumin
• 1 tsp garlic powder
• 1/2 tsp smoked paprika
• 1/4 tsp black pepper

For the assembly:

• 8-10 street taco size tortillas
• 1 large avocado (sliced or mashed)
• 1/2 cup crumbled cotija cheese
• 1/4 cup chopped fresh cilantro
• 2 limes (cut into wedges for a bright finish)

Step 1: Prep and Season All Vegetables

• 1 large bell pepper, cut into 1-inch squares
• 1 medium zucchini, sliced into 1/2-inch thick rounds
• 1 medium red onion, cut into 1-inch wedges
• 2 ears corn, husks removed
• 3 tbsp olive oil
• 1 tsp salt
• 1/2 tsp chipotle pepper
• 1 tsp cumin
• 1 tsp garlic powder
• 1/2 tsp smoked paprika
• 1/4 tsp black pepper

Cut the bell pepper into 1-inch squares, slice the zucchini into 1/2-inch thick rounds, and cut the red onion into 1-inch wedges.

Keep the corn whole with husks removed.

In a small bowl, whisk together the olive oil, salt, chipotle pepper, cumin, garlic powder, smoked paprika, and black pepper to create a seasoning paste.

I like to make this mixture ahead so the spices bloom in the oil and develop deeper flavor.

Divide the vegetables between two bowls or a large cutting board, then drizzle the seasoning mixture over them and toss gently until everything is evenly coated.

Step 2: Heat Grill and Cook Vegetables

• seasoned vegetable mixture from Step 1

Preheat your grill to medium-high heat (around 400-425°F).

Place a grill basket on the grates to heat, or prepare foil if you prefer that method.

Once hot, carefully arrange the seasoned vegetables in the grill basket or on foil, keeping the corn whole and grouping similar vegetables together so they cook evenly.

Grill for 5-7 minutes, stirring occasionally, until the vegetables develop light char marks and are tender but still have a slight bite.

The corn will be ready when the kernels pop slightly and show some browning.

Step 3: Warm Tortillas and Prepare Toppings

• 8-10 street taco size tortillas
• 1 large avocado, sliced or mashed
• 1/2 cup crumbled cotija cheese
• 1/4 cup chopped fresh cilantro
• 2 limes, cut into wedges

While the vegetables finish cooking, place the tortillas directly on the grill grates for 30-45 seconds per side to warm and lightly char them, or warm them in a dry skillet on the stovetop.

Remove the corn from the grill and let it cool slightly, then cut the kernels off the cob using a sharp knife.

Arrange your toppings on a platter: slice or mash the avocado, place the cotija cheese in a small bowl, put the cilantro in another bowl, and cut the limes into wedges.

I find that having everything prepped and visible makes the assembly process quick and fun.

Step 4: Assemble and Serve Tacos

• warmed tortillas from Step 3
• grilled vegetables from Step 2
• avocado from Step 3
• cotija cheese from Step 3
• cilantro from Step 3
• lime wedges from Step 3

Place a warm tortilla on a plate and layer it with grilled vegetables from Step 2 (including the corn kernels), a generous dollop of avocado, a sprinkle of cotija cheese, and a pinch of fresh cilantro.

Squeeze fresh lime juice over the top to brighten all the flavors.

Repeat with remaining tortillas and toppings.

Serve immediately with extra lime wedges on the side.
