Equipment

  • Blender
  • 9x13 inch baking dish

Ingredients

French Toast

  • 8 slices sourdough bread thick cut
  • 2 ripe bananas
  • 1 1/2 cups unsweetened almond milk
  • 1/2 cup pea protein powder unflavored or vanilla
  • 2 tbsp ground flax
  • 2 tbsp maple syrup
  • 1 tsp cinnamon
  • 1/4 tsp salt
  • 1 tbsp coconut oil for greasing pan

For Serving

  • 1/4 cup peanut butter
  • 1/2 cup frozen strawberries warmed

Instructions

  • Preheat oven to 425°F. Tear or cube 8 slices of thick-cut sourdough into roughly 1-inch pieces. Grease a 9x13 baking dish with 1 tbsp coconut oil.
  • In a blender, combine 2 ripe bananas, 1 1/2 cups unsweetened almond milk, 1/2 cup pea protein powder, 2 tbsp ground flax, 2 tbsp maple syrup, 1 tsp cinnamon, and 1/4 tsp salt. Blend for about 30 seconds until completely smooth.
  • Spread the sourdough cubes evenly across the greased baking dish. Pour the blended custard over the bread, pressing down gently so every piece soaks up the liquid. Let sit for 5 minutes.
  • Bake uncovered for 20-22 minutes until the top is golden and the center is set (not jiggly). Edges should look crispy.
  • Cut into 4 portions. Drizzle each serving with 1 tbsp peanut butter and top with warmed strawberries.

Notes

Meal prep: Cool completely, then refrigerate in airtight containers for up to 4 days. Reheat in air fryer or oven at 375°F for 3-5 minutes. Avoid microwave for best texture.
Overnight option: Assemble the casserole, cover, and refrigerate overnight. Bake straight from fridge, adding 3-5 extra minutes to bake time.
Protein powder: Pea protein gives the best structure, but rice or soy protein work as substitutes. For a protein-powder-free version, use 1/4 cup chickpea flour instead (reduces protein to ~12g per serving).
