When you bake marinated tofu at 400 degrees Fahrenheit, you get a nice contrast in texture that really makes this sandwich work – the outside gets crispy and golden while the inside stays tender, and that crispiness won’t get totally soggy when you brush the ciabatta with the leftover marinade. The sesame seeds toast a bit during baking, adding a nutty flavor and extra crunch. The ciabatta bread, with its airy crumb structure, holds up really well against the moist tofu without falling apart. This combo of crispy tofu, soft bread, and the tangy-savory marinade creates different textures that make each bite satisfying and interesting. Using a tofu press* before marinating ensures your tofu block is properly drained and will absorb the sesame marinade more effectively for maximum flavor.
Marinade Makes All the Difference
This recipe relies on a well-balanced marinade that combines umami-rich soy sauce with tangy vinegar and nutty sesame oil, which will infuse the tofu with depth and complexity. The remaining components – crispy bread, fresh vegetables, and toasted sesame seeds – complement the marinated tofu to create a satisfying and flavorful meal. For those looking to prepare tofu regularly at home, investing in a tofu maker set* can simplify the process of creating perfectly textured tofu for all your culinary projects.
Ingredients:
Marinated Sesame Tofu on Ciabatta
by veganpreps.com

Ingredients
- 1/4 cup soy sauce
- 1/4 cup sherry vinegar
- 1/4 cup vegetable oil
- 1/4 cup toasted sesame oil
- 1/4 cup Dijon mustard
- 1 (8-ounce) package extra-firm tofu, pressed and drained
- 2 tablespoons sesame seeds
- 1 large loaf ciabatta bread (or 6 ciabatta rolls), sliced for serving
- 1 seedless cucumber, thinly sliced
- 2 cups arugula
Instructions
- 1Press tofu for at least 15 minutes, then slice into 1/2-inch planks. Whisk together soy sauce, sherry vinegar, vegetable oil, sesame oil, and Dijon mustard in a shallow dish. Add tofu slices and marinate for at least 20 minutes, flipping halfway through. Reserve the marinade.
- 2Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper. Remove tofu from marinade, sprinkle both sides with sesame seeds, and arrange in a single layer on the baking sheet.
- 3Bake tofu for 20 to 25 minutes, flipping once halfway, until golden and firm with lightly toasted sesame seeds.
- 4While tofu bakes, cut ciabatta into sandwich-sized portions and brush cut sides lightly with reserved marinade. Toast cut-side down in a dry skillet over medium heat for 2 to 3 minutes until golden.
- 5Assemble sandwiches: layer arugula on the bottom half of the ciabatta, top with baked sesame tofu planks and cucumber slices, then close with the top half. Serve immediately.
Notes
- Store leftovers in an airtight container in the fridge for up to 4 days.
- This recipe freezes well for up to 3 months. Thaw overnight in the fridge before reheating.
- Adjust seasoning to taste after reheating, as flavors can mellow during storage.
Extra-firm tofu keeps its shape while marinating and baking. Good quality toasted sesame oil really matters here since it gives you that distinctive nutty flavor that makes this sandwich special. The ciabatta bread needs to be fresh and sturdy enough to handle the marinade without getting soggy. For the best sandwich, grab fresh arugula and slice the cucumber right before you put it all together so everything stays crisp and the bread doesn’t get waterlogged.
Marinate Tofu Overnight First

Begin by preparing the marinade that will infuse the tofu with flavor. Whisk together 1/4 cup soy sauce, 1/4 cup sherry vinegar, 1/4 cup vegetable oil, 1/4 cup toasted sesame oil, and 1/4 cup Dijon mustard until well combined. Cut 1 8-ounce package of extra-firm tofu, drained, into 1/4-inch-thick slices and arrange them in a single layer in a shallow dish. Pour the prepared marinade over the tofu, making sure all slices are coated evenly. Cover the dish with plastic wrap and refrigerate overnight, letting the tofu soak up all those delicious soy-vinegar flavors.
The next day, preheat your oven to 400°F. Remove the tofu slices from the marinade, saving the liquid for later use on the bread. Arrange the marinated tofu on a baking sheet and sprinkle generously with 2 tablespoons of sesame seeds. Bake for about 15 minutes until the tofu gets a golden-brown exterior. Once browned, remove from the oven and let the tofu cool to room temperature.
While the tofu cools, prepare the ciabatta bread by cutting 2 loaves into 6 pieces each, then slicing each piece in half horizontally to create sandwich bases and tops. Whisk the reserved marinade again to mix it back together, then brush some of the mixture onto the cut sides of each bread piece. Layer the bottoms with thinly sliced cucumber from 1 seedless cucumber, followed by the cooled tofu slices and 2 cups of arugula. Top with the remaining bread pieces and serve right away.
Try Different Sesame Oils
The sesame oil you choose makes a real difference in how your sandwich tastes, and you’ve got more options than you might think. Light sesame oil has a mild flavor that won’t overpower your tofu, while toasted sesame oil delivers rich, nutty depth. Start with toasted for this recipe since it works well with the soy sauce marinade. If you find it too intense, blend toasted and light oils together. Some brands taste earthier than others, so try different suppliers. Fresh sesame oil matters too – older bottles lose their flavor, so check purchase dates when shopping.
The It Pairs Wonderfully With Chilled Asian Cucumber Salad
A chilled Asian cucumber salad complements this sandwich nicely. Make it by tossing thin cucumber slices with rice vinegar, a touch of sesame oil, and red pepper flakes. The cool, crisp salad provides a nice contrast to the warm, savory sandwich, and the flavors work together nicely. The vinegar matches the sherry vinegar in the marinade, while the sesame oil brings everything together. Serve the salad on the side, and you’ll find each bite tastes more balanced and satisfying. This pairing makes your meal into something really special.
Final Thoughts
Now that you’ve got your sandwich assembled and paired it with that cool cucumber salad, you’re ready to enjoy what you’ve created. The marinated tofu takes in all those rich Asian flavors – soy, vinegar, sesame – creating a filling, protein-packed meal. The crispy edges from baking work well with the soft bread and fresh arugula. The sesame seeds add a nice crunch and nutty taste. This sandwich works great for lunch prep too; just assemble it fresh when you’re ready to eat so the bread stays crispy. You’ve earned this delicious reward.
