This gluten-free French toast casserole not only offers a delectable start to the day but also ensures inclusivity at the dining table.
Why Gluten-Free?
In recent years, the importance of gluten-free options in cooking has become increasingly evident. With a rise in gluten and dairy intolerance, offering gluten-free alternatives like a gluten-free French toast casserole has become essential. Such options not only alleviate symptoms of digestive disorders like IBS and IBD but also promote a healthier gut microbiome, leading to improved overall well-being. Moreover, a gluten-free diet can lead to reduced inflammation in the gut, better digestion, nutrient absorption, and enhanced immune function, making dishes like gluten-free French toast vital for those with sensitivities.

Substitutes
- Bread: It’s crucial to use dry or slightly stale bread to prevent the casserole from becoming soggy. You can leave your bread out overnight or dry it in a 200 degree F oven for about 10 minutes. The bread should dry out but not color or get toasted.
- Milk: Substitute dairy milk with any plant-based milk like almond, cashew, or coconut milk.
- Butter: Use coconut oil or other plant-based butter substitutes for a dairy-free version.
- Sweeteners: Instead of brown sugar, you can use coconut palm sugar or other natural sweeteners.
- Toppings: The casserole is highly customizable. If you don’t have strawberries or blueberries, you can use other fruits or jams. You can also get creative with nuts like cashews or almonds, or even chunky peanut butter
Step-by-Step Cooking Instructions
- Oven Preparation: Preheat your oven to 350°F (177°C). Grease your baking dish with butter.
- Bread Preparation: Chop the gluten-free bread into 1″ cubes and bake in the prepared dish for 5-7 minutes, or just before they turn golden brown. This step is crucial to prevent a soggy casserole.
- Custard Mixture: In your mixing bowl, combine eggs, milk, vanilla extract, ground cinnamon, brown sugar, melted butter, orange zest, and sea salt. Whisk until everything is well combined.
- Assembly: Pour the liquid mixture evenly over the toasted bread pieces in the baking dish. Add frozen blueberries and strawberries, then gently mix.
- Baking the Casserole: Bake the casserole uncovered for 60 minutes. This allows for a fluffy custard center with slightly caramelized edges.
- Final Touches: After removing the casserole from the oven, allow it to cool slightly. Then sprinkle with additional cinnamon and powdered sugar.
- Serving: Add roasted nuts and fresh fruit just before serving to maintain texture and freshness.
- Enjoy: Your gluten-free French toast casserole is now ready to be enjoyed!
