Lemon Herb Tofu Skewers

Of all the recipes that have become staples in our household, this one for Lemon Herb Tofu Skewers holds a special place. I first made it on a whim for a summer barbecue, a little nervous about how it would be received by a crowd accustomed to more traditional grill fare. I was looking for something vibrant, healthy, and substantial enough to be a main course, yet light enough for a warm day. To my absolute delight, they were a runaway success. My kids, who can sometimes be picky about tofu, were grabbing them straight off the platter. My husband, a self-proclaimed grill master, admitted they were one of the most flavorful things he’d eaten all season. The secret, I believe, is the marinade. It’s a bright, zesty explosion of fresh lemon, garlic, and a medley of herbs that penetrates the tofu, transforming it from a blank canvas into a culinary masterpiece. The high heat of the grill creates a perfect texture contrast—a slightly crispy, caramelized exterior giving way to a tender, juicy center. These skewers have since become our go-to for everything from weeknight dinners on the patio to large family gatherings. They’re a beautiful, colorful addition to any table and prove that plant-based cooking can be incredibly satisfying, exciting, and universally loved.

Ingredients

• Extra-Firm Tofu (2 blocks, 14-16 ounces each): This is the star of the show. Using extra-firm tofu is crucial as it holds its shape perfectly during marinating and grilling, preventing it from crumbling on the skewers.
• Olive Oil (1/2 cup): A good quality extra-virgin olive oil forms the base of the marinade, adding richness and helping the tofu to brown beautifully on the grill.
• Fresh Lemon Juice (1/2 cup): From about 2-3 large, juicy lemons. Freshly squeezed juice is non-negotiable here; its bright, zesty flavor is what makes the dish pop.
• Lemon Zest (1 tablespoon): The zest contains essential oils that provide a more intense and aromatic lemon flavor than the juice alone.
• Fresh Parsley (1/4 cup, finely chopped): Adds a fresh, clean, and slightly peppery note that complements the other herbs.
• Fresh Dill (2 tablespoons, finely chopped): Provides a unique, slightly tangy, and grassy flavor that pairs wonderfully with lemon.
• Fresh Oregano (1 tablespoon, finely chopped): Or 1 teaspoon dried. Fresh is preferred for its robust, earthy flavor that stands up to grilling.
• Garlic (4 cloves, minced): A fundamental aromatic that adds depth and a savory punch to the marinade.
• Dijon Mustard (1 tablespoon): Acts as an emulsifier to keep the marinade from separating and adds a subtle, tangy complexity.
• Maple Syrup (1 teaspoon): Just a touch to balance the acidity of the lemon and help with caramelization on the grill. You can also use agave nectar.
• Salt (1 teaspoon): Essential for enhancing all the other flavors in the marinade.
• Black Pepper (1/2 teaspoon, freshly ground): Adds a gentle, spicy warmth.
• Red Bell Pepper (1 large, cut into 1-inch squares): For sweetness, a vibrant splash of color, and a tender-crisp texture.
• Zucchini (1 large, cut into 1/2-inch thick rounds): Adds a mild, fresh flavor and becomes wonderfully tender when grilled.
• Red Onion (1 large, cut into 1-inch wedges): Provides a sweet and savory flavor that caramelizes beautifully on the grill.
• Cherry Tomatoes (1 pint): These burst with juicy sweetness when grilled, adding another layer of flavor and texture.
• Wooden or Metal Skewers (8-10): If using wooden skewers, be sure to soak them in water for at least 30 minutes before use to prevent them from burning on the grill.

Instructions

1. Press the Tofu: This is the most critical step for achieving the perfect texture. Remove the tofu blocks from their packaging and drain the water. Wrap each block in several layers of paper towels or a clean kitchen towel. Place them on a plate and put something heavy on top, like a cast-iron skillet, a few cookbooks, or a tofu press. Let the tofu press for at least 30 minutes, but for best results, press for 1 hour. This process removes excess water, allowing the tofu to absorb more marinade and become firmer and chewier.
2. Prepare the Marinade: While the tofu is pressing, you can prepare the flavor-packed marinade. In a medium-sized bowl, whisk together the olive oil, fresh lemon juice, lemon zest, chopped parsley, dill, oregano, minced garlic, Dijon mustard, maple syrup, salt, and freshly ground black pepper. Whisk until the mixture is well combined and slightly emulsified. Taste and adjust seasoning if necessary.
3. Marinate the Tofu: Once the tofu is well-pressed, unwrap it and cut it into 1-inch cubes. Place the tofu cubes in a shallow dish or a large zip-top bag. Pour about two-thirds of the prepared marinade over the tofu, reserving the remaining one-third for later basting. Gently toss the tofu cubes to ensure they are all evenly coated. Cover the dish or seal the bag and let the tofu marinate in the refrigerator for at least 1 hour. For an even more intense flavor, you can marinate it for up to 24 hours. The longer it marinates, the more flavor it will absorb.
4. Prepare the Vegetables: While the tofu is marinating, wash and chop your vegetables. Cut the red bell pepper, zucchini, and red onion into uniform, 1-inch pieces so they cook evenly with the tofu. Leave the cherry tomatoes whole. Place all the prepared vegetables in a large bowl.
5. Assemble the Skewers: If you’re using wooden skewers, now is the time to remember to soak them in water. Once the tofu has finished marinating, you can begin assembling. Thread the tofu cubes and vegetables onto the skewers, alternating them for a colorful and balanced presentation. A good pattern might be tofu, bell pepper, zucchini, onion, cherry tomato, and then repeat. Leave a little space at the top and bottom of each skewer for easier handling.
6. Grill the Skewers: Preheat your grill (outdoor or indoor grill pan) to medium-high heat. Clean the grill grates well and lightly oil them with a high-smoke-point oil (like canola or avocado oil) to prevent the tofu from sticking. Place the assembled skewers on the hot grill. Grill for about 10-15 minutes, turning them every 3-4 minutes, until the tofu is golden brown with beautiful char marks and the vegetables are tender-crisp.
7. Baste and Serve: During the last few minutes of grilling, brush the skewers with the reserved one-third of the marinade. This final basting step adds a fresh burst of lemon-herb flavor. Once cooked, carefully remove the skewers from the grill and place them on a serving platter. Let them rest for a couple of minutes before serving hot.

How to Serve

These Lemon Herb Tofu Skewers are incredibly versatile and can be the centerpiece of many different meals. Here are some delicious ways to serve them:

• As a Classic BBQ Main:
  • Serve the skewers directly on a platter, garnished with extra fresh parsley and a few lemon wedges on the side for squeezing.
  • Pair with classic barbecue side dishes like a creamy potato salad, a crisp coleslaw, or grilled corn on the cob.
• Over a Bed of Grains:
  • Slide the tofu and vegetables off the skewers onto a bed of fluffy quinoa for a protein-packed, gluten-free meal.
  • Serve over a light and fluffy lemon-herb couscous to complement the flavors of the marinade.
  • A simple bed of brown or white rice also works perfectly to soak up the delicious juices.
• In a Salad or Bowl:
  • Create a Mediterranean-inspired grain bowl by adding the skewer contents to a base of farro or bulgur, along with Kalamata olives, cucumbers, and a dollop of hummus.
  • Deconstruct the skewers and toss the grilled tofu and vegetables into a large leafy green salad with a light vinaigrette for a satisfying and healthy lunch.
• With Breads and Dips:
  • Serve alongside warm, soft pita bread. Guests can slide the contents of the skewer into the pita to create their own sandwich.
  • Pair with a cool and creamy dip like a traditional Greek tzatziki (yogurt-cucumber dip) or a dairy-free cashew-based version. The coolness of the dip is a fantastic contrast to the smoky, warm skewers.
  • A vibrant romesco sauce or a simple garlic aioli would also be excellent dipping companions.

Additional Tips

1. Don’t Skip the Press: It bears repeating: pressing the tofu is the single most important step. Unpressed tofu is water-logged. It won’t absorb the marinade well, won’t get crispy, and is more likely to fall apart on the grill. If you plan to make tofu often, a dedicated tofu press is a worthwhile, inexpensive investment.
2. Maximize Marination: While 1 hour is the minimum, letting the tofu marinate for 4-6 hours, or even overnight, will make a world of difference. The flavors will penetrate deeper into the tofu cubes, resulting in a much more savory and impactful final dish.
3. Soak Your Skewers Properly: If you are using bamboo or wooden skewers, don’t just give them a quick rinse. They need to be fully submerged in water for at least 30 minutes. This saturates the wood with water, preventing it from catching fire and burning to a crisp over the high heat of the grill.
4. Uniform Vegetable Cuts: Pay attention to how you chop your vegetables. Cutting the zucchini, bell peppers, and onions to a size similar to your tofu cubes (around 1 inch) ensures everything cooks at a relatively even rate. If your veggies are too small, they’ll burn before the tofu is done; if too large, they’ll still be raw when the tofu is perfectly charred.
5. Master Your Grill Heat: Don’t grill these skewers on scorching high heat. Medium-high is the sweet spot. It’s hot enough to create those beautiful grill marks and a nice char but not so hot that the marinade burns before the tofu and vegetables have a chance to cook through.
6. The Double-Oiling Trick for No Sticking: Tofu can be notorious for sticking to grill grates. To combat this, use a two-pronged approach. First, ensure there’s enough oil in your marinade. Second, right before you place the skewers down, use a paper towel dipped in a high-smoke-point oil to grease the hot grill grates. This creates a non-stick barrier.
7. Reserve Marinade for Basting: Never use the marinade that the raw tofu was sitting in for basting, as this can lead to cross-contamination. Always set aside a portion of the fresh, untouched marinade at the beginning specifically for brushing on the skewers during the final minutes of cooking. This re-hydrates the exterior and adds a final, vibrant layer of flavor.
8. Prep Ahead for Easy Entertaining: You can do most of the work for this recipe well in advance. Press and marinate the tofu overnight. Chop the vegetables and store them in an airtight container in the fridge. You can even assemble the skewers a few hours ahead of time. Just lay them on a baking sheet, cover, and refrigerate. When your guests arrive, all you have to do is fire up the grill.

FAQ Section

1. What is the best type of tofu to use for grilling?
For any recipe that involves grilling, pan-searing, or stir-frying, extra-firm or super-firm tofu is the best choice. These varieties have the lowest water content and the densest texture, which means they hold their shape exceptionally well under high heat and when being handled on skewers. Firm tofu can work in a pinch if pressed very well, but avoid using soft or silken tofu, as they are far too delicate and will completely disintegrate.

2. Can I bake these Lemon Herb Tofu Skewers instead of grilling them?
Absolutely! Baking is a great alternative if you don’t have a grill. Preheat your oven to 400°F (200°C). Arrange the assembled skewers on a baking sheet lined with parchment paper (to prevent sticking). Bake for 20-25 minutes, flipping them halfway through. For the last 2-3 minutes of cooking, you can turn on the broiler to help get a little more color and char on the edges. Remember to baste with the reserved marinade before they go in the oven or during the flip.

3. How can I make these skewers in an air fryer?
Air frying is another excellent method. Depending on the size of your air fryer basket, you may need to use shorter skewers or simply cook the marinated tofu and vegetables without skewering them. Preheat your air fryer to 375°F (190°C). Arrange the skewers or the tofu/veg mix in a single layer in the basket (work in batches if necessary). Air fry for 12-15 minutes, flipping or shaking the basket halfway through, until the tofu is golden and crispy.

4. Can I use different herbs in the marinade?
Of course! This recipe is very flexible. While the lemon-dill-parsley combination is classic, feel free to experiment. Fresh rosemary and thyme would create a more robust, woodsy flavor profile. Fresh mint could add a refreshing twist perfect for summer. You could also lean into a spicier direction by adding a pinch of red pepper flakes or a dash of your favorite hot sauce to the marinade.

5. How should I store and reheat leftovers?
Store any leftover skewers in an airtight container in the refrigerator for up to 3-4 days. The flavors will continue to meld, and they are often just as delicious the next day. To reheat, you can gently warm them in the microwave, but for the best texture, place them in a 350°F (175°C) oven or a toaster oven for about 10 minutes, or until warmed through. This helps to crisp up the exterior again.

6. Is this recipe gluten-free?
This recipe is naturally gluten-free as written. Tofu, vegetables, herbs, and olive oil do not contain gluten. The only ingredient to be mindful of in similar marinades is soy sauce. This recipe uses salt for its savory component, but if you were to add soy sauce for an umami boost, you would need to use tamari or a certified gluten-free soy sauce to keep the dish gluten-free.

7. Can I freeze these tofu skewers?
Yes, you can freeze them, and it’s best to do so after they are cooked. Raw tofu that has been marinated can sometimes develop a slightly spongier texture after freezing and thawing. To freeze, let the cooked skewers cool completely. You can then freeze them on a baking sheet in a single layer before transferring them to a freezer-safe bag or container. This prevents them from sticking together. They can be stored in the freezer for up to 2 months. Reheat from frozen in the oven.

8. My tofu was still a bit soft or crumbly. What did I do wrong?
This issue almost always comes down to one of two things: the type of tofu used or inadequate pressing. If you used medium or firm tofu, it might not have been sturdy enough. If you used extra-firm tofu and it was still soft, it likely needed to be pressed for a longer period. Pressing for a full hour can make a significant difference. Also, be gentle when tossing the tofu in the marinade and threading it onto the skewers to prevent it from breaking apart before it even hits the grill.
