  • Customizable: Adjust spice levels or sweetness to your liking.

Ingredients

  • 1/4 cup soy sauce (or tamari for gluten-free)
  • 1/4 cup apple cider vinegar
  • 2 tablespoons olive oil
  • 2 tablespoons maple syrup (or agave nectar)
  • 2 cloves garlic, minced
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon cayenne pepper (optional for heat)
  • 1 teaspoon liquid smoke (optional but recommended for authentic BBQ flavor)
  • 1 tablespoon tomato paste

Equipment

  • Mixing bowl – to combine all marinade ingredients.
  • Whisk or fork – for blending the marinade smoothly.
  • Measuring spoons and cups
  • Resealable plastic bag or shallow dish – for marinating vegetables.
  • Grill, grill pan, or oven – for cooking the marinated veggies.
  • Basting brush (optional) – to apply extra marinade while grilling.

Instructions

  1. Prepare the marinade: In a mixing bowl, whisk together the soy sauce, apple cider vinegar, olive oil, and maple syrup until well combined.
  2. Add the seasonings: Stir in the minced garlic, smoked paprika, ground cumin, black pepper, cayenne pepper (if using), liquid smoke, and tomato paste. Whisk thoroughly to create a smooth, flavorful sauce.
  3. Choose your vegetables: Select firm vegetables that grill well, such as sliced bell peppers, zucchini, mushrooms, eggplant, asparagus, or cubes of firm tofu.
  4. Marinate: Place your vegetables in a resealable plastic bag or shallow dish and pour the marinade over them. Toss gently to coat all pieces evenly.
  5. Refrigerate: Seal the bag or cover the dish and refrigerate for at least 1 hour, preferably 3-4 hours, to allow the flavors to deeply penetrate the veggies.
  6. Preheat your grill or oven: If grilling, heat to medium-high. For oven roasting, preheat to 425°F (220°C) and line a baking sheet with parchment paper.
  7. Cook the vegetables: Remove the veggies from the marinade, letting excess drip off. Grill for 4-6 minutes per side or roast in the oven for 20-25 minutes, turning halfway through, until tender and caramelized.
  8. Serve and enjoy: Serve the grilled vegetables hot off the grill with your favorite sides.

Tips & Variations

“For an extra smoky flavor, don’t skip the liquid smoke—it really makes the marinade pop!”

  • Make it spicy: Add a teaspoon of chili powder or a dash of hot sauce to amp up the heat.
  • Sweeten it up: Swap maple syrup for brown sugar or honey if you’re not strictly vegan.
  • Herbs: Fresh herbs like thyme, rosemary, or cilantro can be added for an herbal twist.
  • Use as a dipping sauce: Reserve some marinade before adding veggies and reduce it in a saucepan to create a tasty dipping sauce.
  • Try different proteins: This marinade is also excellent on tempeh, seitan, or even vegan meat substitutes.
