Ingredients for Grilled Chicken Sweet Potato

Here’s everything you’ll need to make this flavor-packed meal—I promise, it’s all simple stuff you might already have. The key is prepping ingredients right (trust me, I’ve learned the hard way with mushy sweet potatoes!).

• Chicken: 1 ½ to 2 lbs boneless, skinless thighs (breasts work too, but thighs stay juicier on the grill)
• Sweet potatoes: 1 ½ lbs (about 3 medium), peeled and sliced into ½-inch spears—don’t skimp on the olive oil toss!
• For marinade: ¼ cup soy sauce (I use reduced-sodium so I can control the salt)
• For sauce: 3 scallions (thinly sliced), 1 ripe avocado, juice of 2 lemons, and 3 tbsp toasted sesame seeds (toast them in a dry pan until golden—it makes all the difference!)

Pro tip: If your sesame seeds aren’t pre-toasted, just give them 2-3 minutes in a skillet. You’ll smell when they’re ready—that nutty aroma is irresistible.

How to Make Grilled Chicken Sweet Potato

Alright, let’s get grilling! This is where the magic happens—that perfect combo of smoky, juicy chicken and caramelized sweet potatoes. I’ve made this so many times I could do it with my eyes closed (but please don’t—grills are hot!). Follow these steps and you’ll have restaurant-quality results right in your backyard.

Step 1: Marinate the Chicken

First things first—pat those chicken thighs dry with paper towels. This little trick helps the soy sauce cling better. Drizzle on the soy sauce and give everything a good toss—I use my hands to make sure every inch gets coated. Here’s the best part: you can grill immediately or let it marinate up to 2 hours for deeper flavor (I usually go for at least 30 minutes if I’ve got the time).

Step 2: Prep Sweet Potatoes

While the chicken hangs out, tackle the sweet potatoes. Peel them (or don’t—I sometimes leave the skin on for extra fiber) and cut them into ½-inch spears. Toss them with a glug of olive oil and a pinch of salt—this helps them get those gorgeous grill marks we all love. Pro tip: make the spears uniform so they cook evenly!

Step 3: Grill Sweet Potatoes and Chicken

Fire up that grill to medium-high! First, lay down those sweet potato spears—they take longer to cook than the chicken. Let them get nice and charred on one side (about 5 minutes), then flip them and add the chicken. Listen for that satisfying sizzle! After 4-5 minutes, flip everything. You’ll know the chicken’s done when it’s browned and reaches 165°F inside.

Step 4: Make the Avocado Sauce

While everything grills, whip up the sauce—it comes together in 2 minutes flat. Mash the avocado (I like it slightly chunky), then stir in the scallions, lemon juice, toasted sesame seeds, and a splash of soy sauce. Taste and adjust—sometimes I add an extra squeeze of lemon for brightness. This sauce is so good you’ll want to put it on everything!

Tips for Perfect Grilled Chicken Sweet Potato

After making this recipe dozens of times (and yes, burning a batch or two), I’ve picked up some foolproof tricks that’ll guarantee grill success every time:

• Marinate like you mean it: Even 30 minutes makes a difference—the soy sauce transforms into this sticky, caramelized glaze that’s to die for.
• Taste your sauce: Before drizzling, dip a sweet potato spear in—you might want an extra squeeze of lemon or pinch of sesame seeds.
• Grease those grates: Fold a paper towel, dip in oil, and grab it with tongs to wipe the grill—no more stuck sweet potatoes!
• Don’t crowd the grill: Give everything space to get proper char. I cook in batches if needed.

Oh, and always keep an eye on those sweet potatoes—they go from perfectly caramelized to charcoal faster than you’d think!

Serving Suggestions

This grilled chicken sweet potato dish is crazy versatile—I love serving it three ways: piled high with a crisp green salad for freshness, over fluffy quinoa for extra protein, or with simple steamed greens when I want something light. The leftovers? Even better! Just toss everything in a 350°F oven for 10 minutes or until warmed through—those sweet potatoes get even sweeter the next day.

Ingredient Substitutions

No soy sauce? No problem! Here are my favorite swaps when I’m improvising:

• Tamari or coconut aminos work beautifully instead of soy sauce—great for gluten-free friends.
• Lime juice adds a different zing if you’re out of lemons (I’ve even used orange in a pinch).
• Pumpkin or sunflower seeds make crunchy alternatives to sesame seeds—just toast ’em first!

For vegan folks, skip the chicken and grill extra sweet potatoes with tofu or portobellos—the sauce ties everything together!

FAQs About Grilled Chicken Sweet Potato

Got questions? I’ve got answers! Here are the things people ask me most about this recipe:

Are grilled sweet potatoes healthy? Absolutely! They’re packed with fiber, vitamin A, and antioxidants—way better than fries. The grilling caramelizes their natural sugars without adding much fat.

How long do leftovers last? Store everything in airtight containers for up to 3 days in the fridge. The avocado sauce might darken (still safe!), so I sometimes make it fresh for leftovers.

What’s the best way to reheat? Skip the microwave—it makes sweet potatoes soggy. Toss everything in a 350°F oven or air fryer for 5-7 minutes to revive that crispy texture.

Can I use chicken breasts? Sure, but watch them closely—they dry out faster than thighs. I pull them at 160°F since they’ll keep cooking off the grill.
