Overnight Cinnamon Roll French Toast Casserole

Recipe Ingredients

A few simple ingredients come together to turn Pillsbury™  Cinnamon Rolls into a cozy, custard-soaked French toast casserole—perfect for breakfast or brunch.

Pillsbury™ Cinnamon Rolls with Original Icing: These are the star of this bake! They add sweetness, warm spice, and soft, fluffy texture, making the dish feel indulgent and special with minimal effort. The icing brings extra flavor without the need for additional sugar or spices.

Eggs: These are essential in this recipe because they create the custard that soaks into the cinnamon rolls, giving the bake its soft, rich, French toast-like texture. They also help bind everything together as it bakes.

Other Ingredients: Half-and-half adds richness to the custard, while corn syrup gives a touch of sweetness and helps create a smooth texture. Vanilla adds warm, cozy flavor, and a pat of butter on top brings a rich, melty finish.

How to Make Overnight Cinnamon Roll French Toast Casserole

Here’s a quick overview of how to make this delicious, custardy French toast bake. Keep scrolling for the full directions!

1. Bake the Rolls

Bake and ice Pillsbury Cinnamon Rolls according to package directions, then let cool slightly. Slice each roll into three pieces and arrange in a greased baking dish.

2. Make the Egg Mixture

While the rolls are baking, whisk together the custard base: eggs, half-and-half, corn syrup, and a splash of vanilla. Pour the mixture evenly over the rolls, making sure everything gets completely coated.

3. Refrigerate Overnight

Cover tightly and refrigerate for at least 8 hours or overnight to let the egg mixture fully soak into the rolls.

4. Bake the Casserole

When you’re ready to bake, pop the dish in the oven until everything is golden and bubbly. If your bake turns out too liquidy, it may not have soaked long enough or baked long enough to allow the eggs to set—try baking it a little longer and see if that helps. If it starts getting too dark on top, cover with foil for the last few minutes of baking. Let it cool slightly, then top each serving with a pat of butter for a rich, melty finish.

Storing and Reheating

Have leftovers? This bake keeps well in the fridge and reheats easily for a quick, cozy bite the next day. Here’s how to store it.

Refrigerator

Refrigeration is important because of the egg-based custard. Store in an airtight container in the fridge for up to 3 days. We wouldn’t recommend freezing, as it can affect the texture and quality of the whole dish when thawed and reheated.

Reheating

Warm in a 350°F oven or air fryer for 8 to 10 minutes. For quicker reheating, microwave individual portions on High for 30 seconds to 1 minute, until warm.
