Preheat the oven to 250°F (120°C). Line a large baking sheet with parchment paper or a silicone baking mat to prevent sticking. Arrange the crackers in even rows, upside down, ensuring they do not overlap—seven rows of five fit neatly on a standard cookie sheet.
In a small bowl, whisk together the melted vegan butter, olive oil, and seasoning blend until well combined. Using a pastry brush or a small spoon, generously coat the tops of each cracker with the mixture. Flip each cracker and repeat the process to ensure both sides are seasoned. Optionally, sprinkle a light dusting of nutritional yeast over each cracker for a cheesy, savory boost.
If you notice the seasoning mixture running low midway, simply whisk in a touch more olive oil to stretch it further. Aim for an even, ample coating, though complete saturation is not necessary.
Slide the prepared tray into the oven and bake for 20 minutes until the crackers are crisp and the seasoning is set. Allow them to cool completely on the baking sheet. Serve these flavorful crackers alongside plant-based cheeses, dips, or soups, or enjoy them on their own paired with a glass of wine. Store any leftovers in an airtight container to maintain their crispness.
