Make the vegan custard: In a shallow bowl, whisk together JUST Egg, almond milk, cane sugar, Grand Marnier, orange juice, orange zest, vanilla, nutmeg, and salt until well combined.
Dip the bread: Dip each slice of brioche into the vegan custard mixture for 30 seconds per side. Let your bread sit a little longer if it is thick or dense. Don't rush this part!
Soak: Place the dipped bread in a 9x13 pan or wide shallow dish. Pour the rest of the vegan custard over it. Let it soak for at least 30 minutes, turning the bread over halfway through. Preheat the oven to 400℉.
Drain the bread: Place the slices on a wire rack on a sheet pan immediately before cooking the French toast.
Cook: Heat a nonstick skillet or griddle over medium-low heat for several minutes (at 3 or 4). Add vegan butter and swirl to coat the pan evenly. It should be bubbling. Place the soaked bread slices on the skillet and for 2 - 3 minutes per side, until golden brown - this will depend upon your range and heat.
Bake:Place the slices on a baking sheet and finish them in the oven for 10-15 minutes. If you're in a hurry, you can skip this step, but it makes for a crispy texture on the edges.
To serve, sprinkle generously with confectioner's sugar. Serve with vegan butter and maple syrup. Feel free to add fresh berries or your favorite toppings.
Notes
Before you flip the French toast, check underneath with a spatula to ensure it's browning. Avoid flipping the French toast more than once. If it's browning too fast, reduce the heat.
Please note the calorie count does not include maple syrup or powdered sugar topping. Trader Joe's vegan brioche bread was used to calculate the calorie count.
Storage:
Reheat: Cook in a skillet with melted vegan butter or bake at 350°F for 10 minutes or until heated.
Refrigerator: Once cooled, keep the leftover French toast in an airtight container for up to 3 days.
Freezer: Freeze cooked slices between layers of parchment paper in a zip-top bag for up to 1 month. Thaw overnight in the fridge before warming.
