The Ultimate Vegan Grilled Rhubarb Skewers (That Turn Skeptics Into Believers!)

Let Me Tell You About My Grilling Discovery

Here’s the thing—I thought rhubarb was strictly a pie and jam ingredient until I accidentally discovered the magic of grilling it. I was having a backyard barbecue during my early plant-based days, trying to figure out what to do with all the rhubarb taking over my garden, when I ran out of dessert ideas. On a whim, I tossed some rhubarb pieces on skewers with a quick maple glaze, thinking it might work as a quirky side dish. The first bite completely blew my mind—the heat caramelized the natural sugars while keeping that gorgeous tart bite, and the slight char added this incredible smoky complexity I never expected. Now these skewers are my secret weapon for impressing guests who think they know everything about rhubarb, and I’ve converted more “I don’t like rhubarb” people with this recipe than any other dish I make. Trust me, if you think rhubarb is too tart or weird, grilling transforms it into something absolutely magical.

Here’s the Magic Behind This Vegan Recipe

The secret to fooling everyone is how the grill’s heat caramelizes the maple syrup while creating these gorgeous char marks that make the rhubarb look like something from a fancy restaurant. What makes this irresistible is how the balsamic vinegar adds depth and complexity to balance the sweetness, while the cinnamon creates this warm, cozy flavor that makes people think of comfort food instead of weird vegetables. I never knew rhubarb could taste this sophisticated and approachable when it’s grilled—the heat mellows the tartness while intensifying all the best flavors. The natural sugars in rhubarb caramelize beautifully on the grill, creating edges that are sweet and smoky while the centers stay tender and bright.

Gathering Your Plant Powerhouses (Don’t Stress!)

Fresh rhubarb cut into substantial pieces is absolutely crucial here—look for firm stalks that aren’t too thin or they’ll fall apart on the grill (took me a few attempts to figure out that 1-inch pieces are the perfect size for skewering). I always choose the thickest, most colorful stalks because they hold up best to the heat and create the most gorgeous presentation.

Pure maple syrup becomes your caramelizing hero on the grill—choose the real stuff, not pancake syrup, because the complex flavors really shine when they’re concentrated by heat (game-changer, seriously). The natural sugars create that perfect glossy glaze that makes everything look professional.

Good balsamic vinegar adds that essential depth and tang that elevates this from simple to sophisticated (don’t use the cheap stuff—quality matters when you’re only using a tablespoon). Ground cinnamon creates warmth and makes the whole dish smell incredible, while a pinch of salt brightens all the flavors and makes the sweetness pop.

Here’s How We Create This Vegan Masterpiece

Preheat your grill to medium heat—too hot and the outside burns before the inside gets tender, too cool and you won’t get those gorgeous char marks we’re after. Here’s where I used to mess up my plant-based grilling: I’d try to rush the prep, but taking time to cut uniform pieces makes all the difference.

Cut your rhubarb into 1-inch pieces, making sure they’re all roughly the same size for even cooking. Thread them onto skewers, leaving just a little space between pieces so the heat can circulate properly—this helps everything cook evenly and prevents soggy spots.

Mix your maple syrup, balsamic vinegar, cinnamon, and salt in a small bowl until gorgeously combined. Here’s my plant-based secret: brush this mixture on the rhubarb right before grilling, not too far ahead, because the acid can start breaking down the fruit if it sits too long.

Grill the skewers for 3-4 minutes per side, watching for those beautiful char marks and turning them carefully. The rhubarb should be slightly caramelized and tender but still hold its shape—don’t overcook or it’ll turn to mush. The maple glaze should be bubbling and golden, creating this incredible aromatic situation that makes everyone gather around the grill.

Common Plant-Based Oops Moments (And How to Fix Them)

Rhubarb fell apart on the grill? Your pieces were probably too small or the rhubarb was too ripe and soft—that’s common when grilling delicate vegetables, and it happens to everyone. Next time, choose firmer stalks and cut bigger pieces.

Glaze burned before the rhubarb was done? This usually means your grill was too hot, or you brushed the glaze on too early. Don’t stress—just move the skewers to a cooler part of the grill and brush with fresh glaze to finish cooking.

Flavor seems too tart even after grilling? When this happens (and it will with some rhubarb varieties), just brush with extra maple syrup while they’re still hot. I’ve learned that grilled fruit sometimes needs that final sweetness adjustment.

Fun Plant-Based Twists to Try

When I want extra richness, I’ll add a tablespoon of coconut oil to the glaze mixture—creates this incredible glossy finish that makes everything look professionally catered. My summer version gets fresh thyme sprigs threaded onto the skewers, creating this gorgeous herbal aroma that’s absolutely divine.

For dessert presentation, I love serving these over vanilla plant-based ice cream with a drizzle of the leftover glaze. Sometimes I’ll add chunks of firm tofu or tempeh to make it more substantial as a main course side dish, though the rhubarb is absolutely perfect on its own.

Things People Ask Me About Grilled Rhubarb

Will this actually work if I don’t have a grill? Absolutely! You can make these under the broiler or in a grill pan on the stove—just watch them carefully because they cook faster indoors. The flavor won’t be quite as smoky, but they’ll still be incredible.

Can I make the glaze ahead of time? The glaze keeps perfectly for up to a week in the fridge, and actually gets more flavorful as it sits. Just brush it on the rhubarb right before grilling for the best results.

What’s the best way to serve these? They’re incredible as a side dish with grilled vegetables or plant-based proteins, but I also love them as a light dessert with coconut whipped cream or over yogurt. The versatility is what makes them so special.

Before You Head to the Grill

I couldn’t resist sharing this because it proves plant-based grilling can be creative and unexpected without being complicated. This grilled fruit technique has become my go-to method for turning simple ingredients into something restaurant-worthy that always surprises and delights guests.

The best vegan grilling nights are when everyone’s marveling at these gorgeous caramelized skewers and asking how you thought to grill rhubarb, completely amazed by how something so simple can taste so sophisticated.

Instructions

1. Preheat your grill to medium heat—this is crucial for getting char marks without burning the delicate fruit.
2. Cut rhubarb into uniform 1-inch pieces, making sure they’re all roughly the same size for even cooking.
3. Thread rhubarb pieces onto skewers, leaving small gaps between pieces for proper heat circulation.
4. In a small bowl, whisk together maple syrup, balsamic vinegar, cinnamon, and salt until beautifully combined and glossy.
5. Brush the rhubarb skewers generously with the maple mixture just before grilling—don’t do this too far ahead.

7. Remove from grill when the glaze is bubbling and golden, and the rhubarb feels tender when gently pressed.
8. Serve immediately while hot and at peak caramelized perfection.

Notes:

• Don’t overcook—rhubarb should be tender but not mushy
• If using wooden skewers, soak them for at least 30 minutes to prevent burning
