Balsamic Glazed Veggie Skewers

There are some recipes that just scream “summer,” and these Balsamic Glazed Veggie Skewers are firmly at the top of that list for my family. I first whipped them up for a backyard BBQ, slightly nervous about whether the kids would actually eat a skewer packed with just vegetables. To my utter delight, they were a massive hit! The sweet, tangy balsamic glaze, a deep mahogany color after caramelizing on the grill, transformed simple vegetables into something truly special. Even my notoriously picky nephew was spotted sneaking a second skewer. The vibrant colors of the bell peppers, zucchini, and red onion, glistening with the glaze and lightly charred from the grill, made them as much a feast for the eyes as for the palate. Since that first success, they’ve become a staple for everything from quick weeknight dinners (hello, easy cleanup!) to potlucks where I know I need a reliable, crowd-pleasing, and healthy option. The aroma alone, as they sizzle away, is enough to make everyone gather ’round, eagerly anticipating that first bite.

Ingredients

• For the Balsamic Glaze:
  • 1 cup Balsamic Vinegar: The star of the glaze; choose a good quality one for the best flavor.
  • 1/4 cup Brown Sugar (packed): Adds sweetness and helps the glaze thicken and caramelize. Maple syrup can be a good substitute.
  • 1 tablespoon Soy Sauce (or Tamari for gluten-free): Adds a savory depth and umami.
  • 1 clove Garlic (minced): Provides an aromatic, pungent base note.
  • 1/2 teaspoon Dijon Mustard: Acts as an emulsifier and adds a subtle tang.
• For the Veggie Skewers:
  • 1 large Red Bell Pepper: Sweet, vibrant, and holds up well to grilling.
  • 1 large Yellow or Orange Bell Pepper: Adds another layer of sweetness and color contrast.
  • 1 large Green Bell Pepper: Offers a slightly more earthy flavor and completes the traffic light color scheme.
  • 1 medium Red Onion: Its pungent sweetness mellows beautifully on the grill, providing a lovely bite.
  • 1 medium Zucchini: Tender and mildly flavored, it soaks up the glaze wonderfully.
  • 1 medium Yellow Squash: Similar to zucchini, adding another visual and textural element.
  • 8 ounces Cremini or Button Mushrooms: Earthy and meaty, they provide a great texture.
  • 1 pint Cherry or Grape Tomatoes: Burst with juicy sweetness when grilled.
  • 2 tablespoons Olive Oil: Helps the veggies char nicely and prevents sticking.
  • 1 teaspoon Dried Italian Herbs (or a mix of dried oregano, basil, and thyme): Adds a classic Mediterranean flavor.
  • 1/2 teaspoon Salt (or to taste): Enhances all the other flavors.
  • 1/4 teaspoon Black Pepper (freshly ground, or to taste): Adds a gentle warmth.
• Equipment:
  • 8-12 Wooden or Metal Skewers: If using wooden skewers, remember to soak them in water.

Instructions

1. Prepare the Balsamic Glaze:
   • In a small saucepan, combine the balsamic vinegar, brown sugar, soy sauce (or tamari), minced garlic, and Dijon mustard.
   • Bring the mixture to a gentle simmer over medium heat, stirring occasionally to dissolve the sugar.
   • Once simmering, reduce the heat to low and let it cook, stirring occasionally, for about 10-15 minutes, or until the glaze has thickened enough to coat the back of a spoon. It will continue to thicken as it cools.
   • Remove from heat and set aside. You’ll use about half for marinating and half for basting/drizzling.
2. Prepare the Vegetables:
   • Wash all vegetables thoroughly.
   • Cut the bell peppers into 1 to 1.5-inch square pieces, discarding seeds and membranes.
   • Cut the red onion into 1 to 1.5-inch chunks, separating the layers.
   • Trim the ends of the zucchini and yellow squash, then cut them into 1/2-inch thick rounds or half-moons.
   • If the mushrooms are large, you can halve or quarter them. Leave smaller ones whole.
   • Leave the cherry/grape tomatoes whole.
3. Marinate the Vegetables:
   • In a large mixing bowl, combine all the chopped vegetables.
   • Drizzle with olive oil, sprinkle with Italian herbs, salt, and black pepper. Toss gently to coat everything evenly.
   • Pour about half of the prepared balsamic glaze over the vegetables. Toss again to ensure all pieces are lightly coated.
   • Let the vegetables marinate for at least 20-30 minutes at room temperature, or up to 2 hours in the refrigerator. If marinating longer, bring them closer to room temperature before grilling.
4. Assemble the Skewers:
   • If using wooden skewers, make sure they have soaked in water for at least 30 minutes to prevent them from burning on the grill.
   • Thread the marinated vegetables onto the skewers, alternating types and colors for a visually appealing presentation. Try to pack them snugly but not too tightly, allowing heat to circulate.
5. Grill the Skewers:
   • Preheat your grill (outdoor or indoor grill pan) to medium-high heat (around 375-450°F or 190-230°C). Clean and lightly oil the grill grates to prevent sticking.
   • Place the skewers on the preheated grill.
   • Grill for about 10-15 minutes, turning every 3-4 minutes, until the vegetables are tender-crisp and have nice char marks.
   • During the last 5 minutes of grilling, baste the skewers with some of the reserved balsamic glaze. Be careful, as the sugar in the glaze can cause flare-ups if it drips directly onto flames.
6. Serve:
   • Once cooked, carefully remove the skewers from the grill.
   • Drizzle with any remaining balsamic glaze, if desired, and serve immediately.

Preparation Time

• Chopping & Prep: 20-25 minutes (depending on your knife skills and the number of veggies).
• Glaze Preparation: 15-20 minutes (includes simmering time).
• Marinating Time: 30 minutes (minimum), up to 2 hours.
• Grilling Time: 10-15 minutes.
• Total Time (excluding extended marinating): Approximately 1 hour to 1 hour 20 minutes.
  This recipe is fantastic because much of the “active” time is front-loaded with chopping. Once the veggies are marinating and the glaze is made, the grilling process is quick and engaging.

How to Serve

These Balsamic Glazed Veggie Skewers are incredibly versatile. Here are some serving suggestions to make them shine:

• As a Vibrant Side Dish:
  • Pair them with grilled chicken, fish (like salmon or cod), steak, or pork tenderloin for a complete BBQ meal.
  • Serve alongside hearty burgers or sausages.
  • Accompany a creamy pasta dish to add a fresh, tangy counterpoint.
• As a Light Vegetarian/Vegan Main Course:
  • Serve over a bed of fluffy quinoa, couscous, or farro for a satisfying and nutritious meal.
  • Pair with a side of hummus and pita bread, or a crusty artisan loaf.
  • Add some grilled halloumi (for vegetarians) or marinated tofu/tempeh cubes to the skewers for extra protein.
• For Parties and Gatherings:
  • Arrange them beautifully on a platter as an eye-catching appetizer.
  • Provide a small bowl of extra balsamic glaze for dipping.
  • Consider making mini-skewers for easier mingling and bite-sized enjoyment.
• With Complementary Garnishes and Sauces:
  • Sprinkle with fresh chopped parsley, basil, or chives for a burst of freshness and color before serving.
  • A dollop of plain Greek yogurt or a light herbed yogurt dip can offer a cool contrast.
  • For a spicier kick, a drizzle of sriracha or a sprinkle of red pepper flakes works well.
• Meal Prep Option:
  • Grill a large batch on the weekend. Remove veggies from skewers and store in an airtight container.
  • Use them throughout the week in salads, wraps, grain bowls, or as a quick side for reheated meals. The flavors often meld and become even better the next day.

Additional Tips

1. Uniformity is Key: Cut your vegetables into roughly the same size pieces (around 1 to 1.5 inches). This ensures they cook evenly on the grill, preventing some from being burnt while others are still raw.
2. Soak Those Skewers: If you’re using wooden or bamboo skewers, don’t skip soaking them in water for at least 30 minutes. This prevents them from catching fire and burning to a crisp on the hot grill. Metal skewers are a great reusable alternative.
3. Don’t Overcrowd the Skewers (or the Grill): While you want the veggies to be snug on the skewer, avoid packing them too tightly. This allows hot air to circulate for even cooking. Similarly, don’t overcrowd the grill itself; cook in batches if necessary.
4. Experiment with Veggies: Feel free to swap in other grill-friendly vegetables based on preference or seasonality. Asparagus spears (cut into 2-inch pieces), Brussels sprouts (halved), chunks of corn on the cob, or even pineapple chunks for a sweet-savory twist can be delicious.
5. Mind the Glaze: Balsamic glaze contains sugar, which can burn easily over high heat. Reserve some glaze for basting during the last few minutes of grilling, or for drizzling after they come off the heat. This ensures a beautiful caramelization without charring too much.
6. Optimal Grill Temperature: Aim for medium-high heat. This allows the vegetables to get those desirable char marks and cook through without burning on the outside too quickly. If your grill runs very hot, you might need to use indirect heat for part of the cooking time.
7. Making the Glaze Ahead: The balsamic glaze can be made up to a week in advance and stored in an airtight container in the refrigerator. It will thicken considerably when cold, so you might need to let it sit at room temperature for a bit or gently warm it to make it pourable again.
8. Double-Skewer Tricky Veggies: Softer items like cherry tomatoes or smaller mushroom pieces can sometimes spin or fall off a single skewer. Using two parallel skewers can provide more stability and make them easier to flip.

FAQ Section

Q1: Can I make these Balsamic Glazed Veggie Skewers in the oven?
A1: Absolutely! If you don’t have a grill or prefer oven-roasting, preheat your oven to 400°F (200°C). Arrange the assembled skewers on a baking sheet lined with parchment paper (for easy cleanup). Roast for 15-20 minutes, flipping halfway through. Baste with extra glaze during the last 5 minutes of cooking. You won’t get the same smoky char, but they’ll still be delicious. Using the broiler for the last 2-3 minutes can help achieve some browning.

Q2: What are the best vegetables to use for skewers?
A2: The best vegetables are those that hold their shape well during grilling and cook in a similar amount of time. Bell peppers (any color), onions (red, white, or Vidalia), zucchini, yellow squash, mushrooms (cremini, button, portobello cut into chunks), cherry/grape tomatoes, and even broccoli florets or Brussels sprouts (blanched first for tenderness) are excellent choices. Firmer options like small new potatoes (parboiled first) also work.

Q3: How do I prevent my vegetables from falling off the skewers?
A3: Cut vegetables into substantial, 1 to 1.5-inch pieces. For softer items like cherry tomatoes or small mushrooms, ensure they are firmly pierced, perhaps even using two parallel skewers for extra support. Don’t overcrowd the skewer, but pack them snugly enough that they support each other.

Q4: Can I prepare the vegetables or the entire skewers ahead of time?
A4: Yes, you can chop the vegetables a day in advance and store them in an airtight container in the refrigerator. You can also assemble the skewers (without the glaze marinade initially, or with just olive oil and herbs) a few hours ahead. Add the balsamic glaze marinade about 30 minutes to 2 hours before grilling. Avoid marinating too long, especially with softer veggies, as the acidity can make them too soft.

Q5: Is this recipe vegan and gluten-free?
A5: This recipe is naturally vegan. To ensure it’s gluten-free, simply use tamari instead of regular soy sauce in the balsamic glaze, as soy sauce often contains wheat. Always double-check the labels of your balsamic vinegar and other condiments if severe allergies are a concern.

Q6: How long do leftover veggie skewers last, and how should I store them?
A6: Leftover grilled vegetable skewers can be stored in an airtight container in the refrigerator for 3-4 days. For best results, remove the vegetables from the skewers before storing. They can be enjoyed cold in salads, or gently reheated in the microwave, oven, or a skillet.

Q7: Can I use different types of vinegar for the glaze?
A7: While balsamic vinegar is traditional and provides a unique sweet-tart flavor profile, you could experiment. Apple cider vinegar with a bit more sweetener could work for a different tang. Red wine vinegar might be too harsh on its own but could be part of a blend. However, for the classic “balsamic glazed” taste, balsamic is essential.

Q8: My balsamic glaze isn’t thickening. What did I do wrong?
A8: The most common reason for a glaze not thickening is not simmering it long enough or at a high enough (but still gentle) temperature. Continue to simmer it gently, ensuring it’s not boiling too rapidly, which can make it bitter. It should reduce by about half its volume. Remember, the glaze will also thicken significantly as it cools. If it’s still too thin once cooled, you can return it to the stovetop and simmer for a few more minutes.
