Summertime grilling isn’t just about burgers and hot dogs; there’s a whole world of colorful, tasty vegetarian recipes that can really amp up your next barbecue. Over the years, I’ve found that grilling veggies brings out flavors you just don’t get on the stove. Whether you’re hosting an all-veggie gathering or looking to impress meat-lovers with something different, there are loads of creative vegetarian grilling recipes that everyone will want to dig into. In this article, I’m sharing my favorite tips, recipes, and tricks to help you master vegetarian grilling at your next summer barbecue.
Why Vegetarian Grilling Deserves a Spot at Your Summer Cookout
Vegetarian grilling dishes are vibrant, quick to prep, and can easily hold their own as the main event on the grill. Roasty flavors develop when you toss asparagus, eggplant, or fresh corn on an open flame. Plus, grilled plantbased mains and sides tend to be lighter, which is a nice break from the usual rich and heavy barbecue choices.
Choosing vegetables for grilling isn’t just for health reasons; it opens up room for more creativity, lets your guests try something new, and is super handy if you’re catering for folks with different dietary needs. The demand for plantforward recipes is growing rapidly, with sales of plantbased foods hitting $8 billion in the U.S. alone according to the Good Food Institute. That number keeps climbing, especially in the summer months as backyard cooking gets into full swing.
Vegetarian grilling isn’t tricky. If you’re new to the concept, all you need is a little knowhow on choosing your produce, learning basic marinating tips, and pairing flavors that pop off the grill.
Best Vegetables and PlantBased Proteins for Grilling
Grilling brings out natural sugars in veggies and adds some char for that classic smoky flavor. Here are some options I always go back to:
- Bell Peppers, Onions & Zucchini: Slice them into thick strips or rings. These absorb marinades well and hold their shape nicely.
- Portobello Mushrooms: Super meaty, great as burger standins or sliced for tacos.
- Corn on the Cob: Soaks up smoky grill flavor and sweetens as it cooks.
- Eggplant: Slice into thick rounds; the flesh becomes creamy when grilled.
- Asparagus and Green Beans: Grill quickly, add a satisfying crunch, and are great finger foods.
- Tofu & Tempeh: High in plantbased protein. I always press and marinate tofu before grilling so it doesn’t stick.
- Paneer: This Indian cheese doesn’t melt on the grill, making it perfect for skewers or kabobs.
Grilled fruit is worth checking out too! Pineapple, peaches, and watermelon develop caramelized edges and juicy centers, making them pretty awesome for both savory sides and desserts.
How to Prep Vegetables and Meatless Proteins for Grilling
Preparing vegetables and plantbased proteins before grilling helps boost flavor and keeps things from drying out. Here are my go-to prep steps:
- Cut Evenly: Slice veggies into even pieces so they cook at the same rate. Big slices work best for mushrooms and eggplant; smaller pieces can be threaded onto skewers.
- Marinate: Marinades add flavor and help prevent sticking. My basic marinade is olive oil, lemon juice, a bit of garlic, salt, and a handful of fresh herbs.
- Oil the Grill: Use a paper towel dipped in vegetable oil and (with tongs) wipe the grill grates before cooking.
- PrePress Tofu: Use a tofu press or sandwich the tofu block between kitchen towels, with a heavy skillet on top, for 15-20 minutes to remove moisture. This trick helps tofu get crispy and keeps it from breaking apart.
- Soak Wooden Skewers: If you love veggie kabobs, soak the skewers in water for at least 30 minutes so they won’t catch fire.
Easy Vegetarian Grilling Recipes to Try
Once you’ve got your prep down, these recipes are always a hit at any backyard gathering. Here are some crowdpleasers that make great mains or sides. If you’re looking to jump into something flavorful and fresh, check out these six amazing veggie grilling ideas.
1. Grilled Portobello Mushroom Burgers
These mushrooms make a juicy, satisfying patty. I brush each side with olive oil, balsamic vinegar, garlic powder, and a sprinkle of black pepper. After grilling five minutes per side, I pop them onto a toasted bun, add lettuce, tomato, and a dollop of pesto or mayo. They work great for both vegetarians and anyone looking to try something a little different.
2. Veggie Skewers with Herb Marinade
Skewers are a great way to use up leftover veggies. I thread chunks of red onion, bell peppers, zucchini, and cherry tomatoes, then toss everything in a simple marinade of olive oil, lemon, oregano, and smoked paprika. Grill on medium heat for about ten minutes, turning until charred and tender.
3. Marinated Grilled Tofu Steaks
After pressing extrafirm tofu, I cut it into thick slices and marinate in soy sauce, garlic, a splash of maple syrup, and sesame oil. I grill each piece for around six minutes per side, making sure to get those grill marks. It’s tasty served on a salad, over rice, or tucked into wraps.
4. Grilled Street Corn (Elote Style)
Corn on the cob gets slathered with a mixture of mayo, chili powder, a squeeze of lime, and a dusting of cotija cheese. Sometimes I swap in feta or leave the cheese off for a vegan version. The flavor is smoky with a little tang and heat.
5. Halloumi and Veggie Kabobs
This cheese is firm and salty, and it browns really well on the grill. I alternate cubes of halloumi with zucchini, bell peppers, and red onion on skewers, lightly brush with olive oil, and grill four minutes per side. The cheese softens without losing its shape.
6. Grilled Peach Caprese Salad
I halve and pit ripe peaches, grill until just charred, and layer them with thicksliced fresh mozzarella, basil, and a drizzle of balsamic glaze. It’s a simple twist on traditional caprese that always gets compliments.
Grilling Tips for the Best Results Every Time
- Direct vs. Indirect Heat: I like to sear vegetables over high heat first for grill marks, then shift them to the side for gentle roasting until they’re tender. Indirect heat helps avoid burning.
- Don’t Overcrowd: Leave a little room between pieces so you get nice char instead of steaming everything together.
- Baste Often: Brush extra marinade or olive oil on halfway through to keep everything juicy.
- Check Frequently: Veggies cook quickly. A little char is great, but things like asparagus or thinsliced eggplant can scorch in a blink.
- Rest After Grilling: I usually rest grilled tofu or mushrooms for a couple minutes on a plate before serving so they retain juices.
Common Challenges and How To Solve Them
Like any style of cooking, there can be little bumps along the way with vegetarian barbecue. Here’s what I’ve learned from some summer grilling mishaps and how I solved them:
- Veggies Sticking to the Grill: Oiling both the grill and the vegetables right before grilling really cuts down on sticking. A good marinade with a bit of fat helps too.
- Bland Flavors: Salt is your friend, and so are bold herbs, spices, and zesty sauces. I really notice a difference when I finish grilled veggies with a squeeze of lemon or a dash of finishing salt.
- Dry Plant Proteins: Tofu and tempeh dry out fast. A marinade adds moisture and flavor. Slicing thick, grilling over medium heat, and basting while they cook keeps them juicy.
- Uneven Cooking: Cutting veggies evenly and arranging them according to how quickly they cook solves this issue. For example, onions and peppers first, fastercooking tomatoes and zucchini later in the same session.
How I Prep For a Vegetarian Barbecue Party
When I’m expecting a crowd, I try to set myself up for a relaxed grilling session. I chop veggies ahead, mix up a couple marinades in big jars, and soak skewers in the morning. Dips like hummus or tzatziki and plenty of grilled pita are almost always in my spread; super easy, always popular. I also like to throw together a cold pasta salad with roasted peppers or grilled corn. It adds variety and brings out more smoky flavor from your core barbecue lineup.
Cool Sides, Sauces, and Toppings for Your Grilled Veggies
- Sauces: Chimichurri, cilantro yogurt dip, chipotle mayo, or garlic aioli are all flavorful additions. Making a homemade sauce lets you control the spice and flavor, ensuring it matches your grilled veggies perfectly.
- Sides: Couscous salads, quinoa pilafs, and bean salads pack well for outdoor eating and are filling.
- Toppings: Toasted nuts, crumbled feta, pomegranate seeds, and quickpickled onions kick things up a notch. Throw some fresh herbs like parsley or cilantro on top for a pop of color and flavor.
Desserts stay simple: grilled pineapple slices or bananas dusted with cinnamon and served with a scoop of vanilla ice cream; super simple but always a hit. If you want something more indulgent, try grilling stone fruits and drizzling them with honey or a bit of melted chocolate.
Frequently Asked Questions About Vegetarian Grilling
People ask me all sorts of questions at summer cookouts, so I figured I’d answer a few here.
Question: What’s the best way to keep veggies from burning on the grill?
Answer: I use medium heat and flip veggies often. Marinades or light oiling add a barrier against burning, and indirect heat is great for finishing thicker pieces.
Question: Can I grill frozen vegetarian burgers or patties?
Answer: Absolutely! Just keep an eye on them and flip once they’re firm enough. Sometimes a little oil on the grill surface keeps them from sticking as they thaw.
Question: Is there an easy way to make vegan barbecue sauces?
Answer: Tons of classic barbecue sauces are easy to veganize; swap in maple syrup or agave for honey and use tomato paste, vinegar, and spices as the base. Many storebought ones are “accidentally vegan” already, so just check the label.
