Crispy Zucchini Sandwich Ingredients

The star of this sandwich recipe is the crispy baked zucchini. But, feel free to mix up the veggies in this sandwich to suit your taste. Some other options include mushrooms, tomatoes, and arugula. Here are the ingredients you will need for this delicious vegan sandwich:

Fresh zucchini – Try to choose a larger zucchini, but small ones will do just fine.
Chickpea flour – can be substituted with any flour, but I find that chickpea gives it a crispier bite.
Tapioca flour – can be substituted with corn starch or arrowroot powder.
Non-dairy milk. I prefer soy milk or oat milk.
Panko breadcrumbs
Spices – like smoked paprika, onion powder, garlic powder, salt, and pepper.
Nutritional yeast – this gives the breading a cheesy parmesan-like flavor that brings this sandwich up a level.
Spray oil – I used avocado spray oil. This can easily be omitted if you are following an oil-free plant based diet, just make sure to like the baking sheet with a silicone baking mat or baking paper.
Bread – I used focaccia rolls, but any bread will do.
Roasted red peppers – I used store-bought roasted peppers.
Hummus
Fresh spinach – Or any dark leafy green, like kale or arugula.
Vegan Mozzarella – I used Miyoko’s Creamery Plant Milk Mozzarella.
Marinara sauce

How to Make Crispy Zucchini

Making the breaded zucchini for this recipe is fairly simple. Just batter it, bread it, and bake it! Here are the steps to make it:

Prepare the zucchini by trimming the ends and slicing it crosswise into long planks that are about 1/3-inch thick.
Mix the batter by whisking together the chickpea flour, tapioca flour, and non-dairy milk.
Make the breading by combining the panko breadcrumbs, spices, and nutritional yeast.
Dip each zucchini slice into the batter, then into the breading. Make sure to fully coat the zucchini with both.
Arrange the breaded zucchini on a lined baking sheet so they aren’t touching. Spray with some oil, if using.
Bake for 15 minutes, flip, and bake another 10 minutes. Note: the size of the zucchini will alter the baking time. Make sure to bake until gold and crispy.
Assemble the veggie sandwich by layering hummus, spinach, crispy zucchini, vegan mozzarella, and roasted peppers. Spread marinara sauce on the top piece of bread and place on the sandwich.

Storage and Reheating Tips

As with all breaded foods, the crispy zucchini will not stay crispy during storage. However, you can reheat in the oven at 400F (205C) or in an air-fryer for a few minutes to get it crispy again.

You can chose to meal prep this recipe and store assembled sandwiches in sealed containers in the fridge for the week. They will still taste delicious hot or cold!
