(Good Things Utah) The fantastic Mary Susan Jenkins from Baking It Beautiful is in the kitchen and making Lemon Blueberry Croissant French Toast with a Lemon streusel on top that makes it phenomenal!


  • 13 cups croissants, cut up (about 8 large Costco croissants)
  • 1½ cup milk
  • 5 eggs
  • 1 tsp vanilla
  • Zest of 1 lemon
  • 1 ½ cups blueberries, fresh


  • 1 ½ cup flour
  • ⅓ cup granulated sugar
  • ¼ cup butter, melted
  • Zest of 1 lemon


  • Preheat the oven to 375°. Grease a 9×13 pan and set aside.
  • Cut croissant into bite-sized pieces. I used 8 Costco sized croissants, measuring at about 13 cups.
  • Place the cut croissants into your pan.
  • In a large mixing bowl, whisk together the milk, eggs, vanilla, and lemon zest. Once it’s mixed well, pour it on top of the croissants. Use a spatula to mix the egg mixture so all of the croissants are wet.
  • Evenly distribute the blueberries throughout the casserole pan using a spatula if necessary.

Lemon Streusel

  • Melt the butter in a microwave safe pan.
  • Add the flour, sugar, and zest. Stir until combined.
  • Using your hands, sprinkle the streusel all of the top. If you are like my family, you’ll want to double the streusel part. It’s so yummy!
  • Bake in the oven for 30-35 minutes or until the egg mixture is cooked through.
  • Serve plain or with whipped cream or buttermilk syrup.
