Grilled Zucchini Sandwich
Ingredients
Scale
  • 8 slices sandwich bread
  • 2 teaspoons Dijon mustard
  • 1 cup shredded plant-based cheese
  • 1/4 cup fresh basil, finely chopped
  • 1 cup zucchini, grated and thoroughly drained
  • 1 teaspoon plant-based butter or olive oil
  • 1/2 teaspoon salt
Instructions
  1. 1Grate the zucchini with a box grater and place it onto an old kitchen towel. Sprinkle the grated zucchini with salt, then leave it to rest for 15 minutes so the excess moisture can be drawn out.
  2. 2Once the resting time is complete, gather the towel and twist it firmly to press out as much liquid as possible. Transfer the squeezed zucchini to a clean bowl only after it feels relatively dry.
  3. 3Add the shredded plant-based cheese and chopped basil to the bowl with the zucchini. Stir until the filling is evenly mixed.
  4. 4Spread the Dijon mustard over 4 slices of bread. Divide the zucchini mixture evenly among the remaining 4 slices, using about 1/2 cup of filling per sandwich. Place the mustard-coated slices on top to close each sandwich.
  5. 5Set a skillet over medium-high heat and coat the surface with the plant-based butter or olive oil. When the pan is hot, add the sandwiches and cook on both sides until the bread is crisp and golden and the cheese has melted fully.
  6. 6Remove the sandwiches from the skillet and let them cool briefly. Slice and serve while still hot.
Notes
Freshly chopped basil gives the sandwich the best aroma. A mozzarella-style plant-based cheese, such as Daiya shreds, works well for a smooth melt.

The exact quantities and specific types of ingredients, such as the precise amount of cheese or the variety of bread, are detailed within the accompanying recipe card. This ensures you have all the necessary information for a successful culinary creation.

Variations

One of the most exciting aspects of this grilled zucchini sandwich is its adaptability. For those following a vegan lifestyle, simply ensure you use vegan bread and vegan butter or olive oil. The plant-based cheese and butter in the base recipe are already suitable, so a vegan version is readily achievable without compromising flavor or texture. This makes it an inclusive option for many dietary preferences.

If you are looking to lower your carbohydrate intake, consider swapping the traditional bread for large lettuce leaves or portobello mushroom caps. You can grill the mushroom caps until tender before stuffing them, or wrap the zucchini filling in sturdy lettuce like romaine or iceberg for a light, fresh wrap. This variation offers a delightfully different texture and flavor profile while keeping the core essence of the sandwich intact.

To add a touch of Mediterranean flair, consider incorporating crumbled feta-style plant-based cheese into the zucchini mixture. You could also add a pinch of dried oregano or a small amount of finely chopped sun-dried tomatoes. A light drizzle of balsamic glaze over the finished sandwich can further enhance these new flavors, creating a truly gourmet experience.

How to Prepare Grilled Zucchini Sandwich

Step 1: Preparing the Zucchini

Begin by washing your zucchini thoroughly, ensuring it’s free from any dirt or blemishes. Grate the zucchini using a box grater, aiming for strands that are not too fine but also not too thick. Place the grated zucchini onto a clean kitchen towel or a few layers of paper towels, spreading it out evenly.

Sprinkle the grated zucchini generously with salt, distributing it evenly across the surface. Let this mixture sit for approximately 15 to 20 minutes. The salt will work to draw out excess moisture from the zucchini, a critical step for preventing a soggy sandwich filling. This resting period is key to achieving the right consistency.

After the resting period, it’s time to squeeze out the liquid. Gather the corners of the kitchen towel tightly and twist them firmly, pressing out as much water as you possibly can. You will be surprised by the amount of liquid that is released. The drier the zucchini, the better your sandwich filling will hold together and cook properly.

Step 2: Combining the Filling Ingredients

Once you have thoroughly squeezed out the moisture from the zucchini, transfer the drier, grated zucchini to a clean mixing bowl. Ensure the bowl is large enough to comfortably hold all the ingredients and allows for easy mixing. This step ensures you are starting with a well-prepared base for your sandwich’s heart.

Add the shredded plant-based cheese and the finely chopped fresh basil to the bowl with the drained zucchini. Stir everything together gently but thoroughly, ensuring that the cheese and basil are evenly distributed throughout the zucchini mixture. The goal is a cohesive filling that isn’t watery or falling apart.

Take a moment to taste the mixture, adjusting salt if necessary, although the initial salting of the zucchini usually provides enough seasoning. The fresh basil should provide a vibrant aroma, and the cheese should start to meld with the zucchini. This beautifully combined filling is now ready to be assembled onto the bread.

Step 3: Assembling the Sandwiches

Select your preferred sandwich bread; a sturdy variety works best as it can hold the filling without becoming too soft. Lay out four slices of bread, and on the interior side of each slice, spread a thin, even layer of Dijon mustard. This tangy condiment adds a wonderful depth of flavor and helps cut through the richness of the cheese.

Next, divide the prepared zucchini and cheese mixture equally among the remaining four slices of bread, which will be the bottom halves of your sandwiches. Aim for a consistent amount of filling on each slice to ensure even cooking and a balanced bite. The filling should be piled neatly and not overflow the edges.

Carefully place the mustard-spread bread slices on top of the filling, creating your sandwiches. Gently press down on the sandwiches to help them hold together and to encourage even contact between the bread and filling. This step seals in the delicious mixture, preparing them for the next stage of cooking.

Step 4: Grilling the First Side

Place a large skillet or griddle over medium-high heat. Allow it to heat up thoroughly before adding any fat; a hot pan is essential for achieving a perfectly crisp and golden exterior on the bread.

Once the skillet is hot, add your chosen plant-based butter or olive oil. Swirl it around to coat the cooking surface evenly. The fat will help the bread toast beautifully and prevent sticking.

Carefully place the assembled sandwiches into the hot skillet, ensuring not to overcrowd the pan. You may need to cook them in batches depending on the size of your skillet. Cook for approximately 3 to 4 minutes on the first side, or until the bread achieves a deep golden-brown color and feels nicely crisp. Peek underneath with a spatula to check progress.

Step 5: Grilling the Second Side

Once the first side of the sandwich is perfectly toasted, it’s time to flip. Use a wide spatula to carefully lift and flip each sandwich, ensuring the filling stays neatly tucked inside. Be gentle to maintain the integrity of the sandwich.

Continue to cook the sandwiches for another 3 to 4 minutes on the second side. During this time, the plant-based cheese inside should be melting beautifully, creating that gooey, comforting center. The bread on this side will also turn a lovely golden-brown and crisp.

Keep an eye on the sandwiches to prevent burning. If the bread is browning too quickly before the cheese has a chance to melt, you can reduce the heat slightly. The goal is a fully melted, warm filling encased in perfectly toasted bread.

Step 6: Resting and Serving

Once both sides of the sandwiches are golden brown and the cheese is thoroughly melted, carefully remove them from the skillet. Place the finished sandwiches onto a cutting board or a clean plate.

Allow the sandwiches to rest for just a minute or two before slicing. This short resting period allows the melted cheese to settle slightly, preventing it from oozing out excessively when you cut into them. It also helps the sandwich hold its shape.

Using a sharp knife, slice the grilled zucchini sandwiches in half, either diagonally or straight across. Serve them immediately while they are still warm and the cheese is perfectly gooey. The contrast between the crisp bread and the warm, tender filling is at its best when fresh from the pan.

Pro Tips for Grilled Zucchini Sandwich

Squeeze, Squeeze, Squeeze: The absolute most critical step for a non-soggy sandwich is thoroughly draining the grated zucchini. Don’t underestimate the power of a good squeeze with a kitchen towel; more moisture removed means a better-textured filling.

Medium-High Heat is Your Friend: Cook these sandwiches over medium-high heat, but be attentive. This heat level is crucial for achieving that beautiful, crisp, golden-brown crust on the bread quickly, ensuring the cheese melts before the bread gets too dark.

Bread Choice Matters: Opt for a sturdy sandwich bread, perhaps a whole wheat, sourdough, or a good quality white bread. Avoid very soft, thin slices that can fall apart under the weight of the filling or turn mushy.

Don’t Overstuff: While it’s tempting to pack in as much filling as possible, overstuffing can lead to the filling escaping during cooking and make the sandwich harder to handle. A moderate amount ensures a neater result and better taste balance.

Fresh Basil is Best: While dried herbs can work in a pinch, the vibrant, aromatic punch of fresh basil is truly what elevates this sandwich. Finely chop it so it distributes evenly within the filling.

Serving Suggestions for Grilled Zucchini Sandwich

Decoration

A simple garnish can make your grilled zucchini sandwich even more appealing. A small sprig of fresh basil placed on top of the cut half adds a pop of color and reinforces the fresh flavor. A light dusting of paprika or a swirl of vegan aioli can also add visual interest and an extra layer of taste.

Side Dishes

This sandwich pairs wonderfully with a variety of sides. A classic tomato soup, especially a creamy vegan version, offers a comforting complement and echoes the warmth of the sandwich. A light, crisp green salad with a zesty vinaigrette provides a refreshing contrast to the rich, grilled flavors.

For a more substantial meal, consider serving these sandwiches alongside roasted sweet potato wedges or crispy oven-baked fries. Another excellent option is a side of quinoa or a simple pasta salad. These additions transform the sandwich into a complete and satisfying meal, perfect for any occasion.

Creative Serving Ideas

Instead of cutting the sandwiches in half, consider cutting them into quarters, making them ideal for a lunch platter or as part of a larger assortment of small bites. You could also serve them open-faced on a bed of arugula or baby spinach for a visually striking presentation.

Experiment with different types of plant-based cheeses, such as a smoked gouda-style or a sharp cheddar-style, to alter the flavor profile of the filling. This simple switch can offer a completely new dimension to the classic grilled zucchini sandwich.

Preparation & Storage

Storing Leftovers

Leftover grilled zucchini sandwiches are best enjoyed fresh, but they can be stored for future consumption. Allow the sandwiches to cool completely before storing them. This prevents condensation from making the bread soggy.

Once cooled, wrap each sandwich tightly in plastic wrap or foil, or place them in an airtight container. Store them in the refrigerator for up to 2 days. While the bread may lose some of its crispness, the filling will remain flavorful.

Freezing

Freezing is not generally recommended for this grilled zucchini sandwich. The texture of the zucchini and melted plant-based cheese can become somewhat mushy or watery upon thawing. Additionally, the bread is very likely to lose its desirable crispness, becoming soft and potentially unappealing.

Reheating

To reheat, the best method is to use a skillet or a toaster oven. Place the sandwich in a dry skillet over medium-low heat and cook, flipping occasionally, until heated through and the bread is crisp again. A toaster oven can also work well, aiming to achieve a similar crispy exterior.

Avoid reheating in the microwave, as this will likely result in a soft, steamed texture for the bread, which is not ideal for this sandwich. The goal is to restore the toasted, crispy quality of the bread and ensure the filling is warm and melty.

Frequently Asked Questions

  1. Can I use fresh zucchini or does it need to be cooked first?

    You use fresh zucchini in this recipe, but the crucial step is to grate it and then thoroughly drain out the excess moisture before mixing it with other filling ingredients. This process of salting and squeezing is what prepares the zucchini to be a perfect filling component. It’s not about cooking it beforehand, but about removing water to concentrate its flavor and improve its texture within the sandwich.

  2. What is the best way to ensure the bread gets crispy and not soggy?

    Achieving a crispy exterior involves a combination of factors. Firstly, using a sturdy type of bread helps immensely, as it can hold up to grilling without disintegrating. Secondly, ensure your skillet is well-heated before adding the sandwiches, and use enough plant-based butter or oil to facilitate even browning. The prior draining of the zucchini is also paramount, as a wetter filling will steam the bread from the inside. Finally, avoid overcrowding the pan, which can lower the temperature and lead to steaming rather than crisping.

  3. Can I add other vegetables or ingredients to the zucchini filling?

    Absolutely, this recipe is wonderfully versatile! You can enhance the zucchini filling by adding finely diced bell peppers, sautéed mushrooms, or a sprinkle of nutritional yeast for a cheesier flavor if you are keeping it strictly dairy-free. A small amount of finely chopped onion or garlic, sautéed beforehand until softened, can also add another layer of savory depth. Just remember to keep the overall moisture content in check by ensuring any added vegetables are also well-drained or cooked until their moisture has evaporated.
