Step‑by‑Step Instructions for Tres Leches French Toast Casserole
Step 1: Prepare the Baking Dish
Start by greasing a 9×13-inch baking pan with butter or cooking spray to prevent sticking. This ensures your delicious tres leches french toast casserole releases easily after baking. Set the greased pan aside and preheat your oven to 350°F (175°C).
Step 2: Macerate Strawberries
In a mixing bowl, combine sliced strawberries with brown sugar and the freshly grated orange zest. Gently stir the mixture, allowing it to sit for about 15-20 minutes. This process helps the strawberries release their juices, creating a sweet syrup that will complement your casserole beautifully.
Step 3: Make Tres Leches Mixture
In a large bowl, whisk together the large eggs, ground cinnamon, vanilla extract, sweetened condensed milk, whole milk, and heavy cream. Continue whisking until the mixture is smooth and well combined; this will be the creamy base for your french toast casserole. The rich texture of the tres leches mixture will make your dish incredibly indulgent.
Step 4: Assemble Casserole
Break the conchas into large pieces and spread them evenly in the prepared baking dish. Spoon the macerated strawberries over the conchas, ensuring they’re distributed nicely. Carefully pour the tres leches mixture over the top, allowing it to soak in. Finally, sprinkle semi-sweet chocolate chips on top, cover with plastic wrap, and refrigerate overnight to let the flavors meld.
Step 5: Bake
The next day, remove the casserole from the refrigerator and uncover it. Dot the top with small pats of butter for added richness. Bake in the preheated oven at 350°F (175°C) for about 40 minutes or until the casserole is set and golden brown on top. The delightful aroma will fill your kitchen as it cooks!
Step 6: Serve
Once baked, let the casserole cool slightly before serving. Dust with powdered sugar for a lovely finish and top with a dollop of whipped cream and any leftover fresh strawberries you like. Serve warm, and pair with maple syrup if you wish, making your tres leches french toast casserole an unforgettable breakfast experience!
