## Ingredients You’ll Need

Before you start, gather these simple ingredients:

* **1 loaf (approximately 1 pound) cinnamon swirl bread:** Opt for a good quality cinnamon swirl bread. Day-old bread works best as it soaks up the custard better.
* **6 large eggs:** These form the base of the custard and provide richness.
* **2 cups milk:** Whole milk will give the richest flavor, but you can also use 2% milk or even non-dairy milk like almond or oat milk.
* **1 cup heavy cream:** Adds extra richness and creaminess to the custard.
* **1/2 cup granulated sugar:** Sweetens the custard and helps create a caramelized top.
* **2 tablespoons pure vanilla extract:** Enhances the overall flavor of the casserole.
* **1 teaspoon ground cinnamon:** Amplifies the cinnamon flavor from the bread.
* **1/4 teaspoon ground nutmeg:** Adds a warm, subtle spice.
* **Pinch of salt:** Balances the sweetness and enhances the other flavors.
* **4 tablespoons unsalted butter, melted:** Used to grease the baking dish and drizzle over the casserole for extra richness.

**Optional Toppings:**

* **Powdered sugar:** For dusting after baking.
* **Maple syrup:** A classic accompaniment.
* **Fresh berries:** Add a pop of color and freshness.
* **Whipped cream:** A decadent addition.
* **Chopped nuts:** Provide a satisfying crunch.
* **Caramel sauce:** For an extra indulgent treat.

## Equipment You’ll Need

* **9×13 inch baking dish:** A standard size for casseroles.
* **Large bowl:** For whisking together the custard ingredients.
* **Whisk:** For thoroughly combining the custard.
* **Measuring cups and spoons:** For accurate ingredient measurements.
* **Knife and cutting board:** For slicing the cinnamon swirl bread.
* **Aluminum foil (optional):** To prevent the top from browning too quickly.

## Step-by-Step Instructions

Follow these easy steps to create the perfect Cinnamon Swirl French Toast Casserole:

**Step 1: Prepare the Cinnamon Swirl Bread**

* Lightly grease a 9×13 inch baking dish with melted butter. This will prevent the casserole from sticking.
* Slice the cinnamon swirl bread into 1-inch thick slices. It’s okay if the slices are not perfectly uniform.
* Arrange the bread slices in a single layer in the prepared baking dish, overlapping them slightly to fit. You want to pack them in snugly.

**Step 2: Make the Custard**

* In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined. Make sure there are no lumps of sugar remaining.

**Step 3: Soak the Bread**

* Pour the custard evenly over the bread slices in the baking dish. Ensure that all the bread is soaked in the custard.
* Gently press down on the bread slices with a spatula or the back of a spoon to help them absorb the custard more thoroughly.

**Step 4: Refrigerate (Optional but Recommended)**

* Cover the baking dish tightly with plastic wrap or aluminum foil.
* Refrigerate for at least 2 hours, or preferably overnight. This allows the bread to fully absorb the custard, resulting in a more flavorful and moist casserole. If you’re short on time, you can bake it immediately, but the longer it sits, the better the texture.

**Step 5: Bake the Casserole**

* Preheat oven to 350°F (175°C).
* Remove the casserole from the refrigerator and let it sit at room temperature for about 15-20 minutes while the oven preheats. This will help ensure even baking.
* Drizzle the remaining melted butter evenly over the top of the casserole. This will create a golden-brown crust.
* Bake for 45-55 minutes, or until the casserole is puffed and golden brown on top. A knife inserted into the center should come out clean.
* If the top starts to brown too quickly, cover the casserole loosely with aluminum foil for the last 15-20 minutes of baking.

**Step 6: Let it Rest**

* Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This allows the custard to set up a bit more.

**Step 7: Serve and Enjoy!**

* Dust with powdered sugar, drizzle with maple syrup, and top with fresh berries, whipped cream, or chopped nuts, if desired.
* Serve warm and enjoy!

## Tips for the Perfect Cinnamon Swirl French Toast Casserole

* **Use Day-Old Bread:** Slightly stale bread absorbs the custard better than fresh bread, preventing the casserole from becoming soggy.
* **Don’t Overbake:** Overbaking will result in a dry casserole. Check for doneness by inserting a knife into the center. It should come out clean.
* **Soak Thoroughly:** Ensure that all the bread slices are fully soaked in the custard for maximum flavor and moisture.
* **Customize with Toppings:** Get creative with your toppings! Experiment with different fruits, nuts, sauces, and spices to create your own unique flavor combinations.
* **Make it Gluten-Free:** Use gluten-free cinnamon swirl bread to make this recipe gluten-free.
* **Vegan Option:** Use plant-based milk, cream, and eggs to create a vegan version of this casserole. There are many great vegan egg replacers available on the market.
* **Spice it Up:** Add a pinch of cayenne pepper to the custard for a subtle kick of heat.
* **Add Chocolate Chips:** Sprinkle chocolate chips over the bread before pouring the custard for a decadent treat.
* **Consider a Streusel Topping:** For added texture and sweetness, create a streusel topping using flour, butter, sugar, and cinnamon. Sprinkle it over the casserole before baking.

## Variations and Additions

This Cinnamon Swirl French Toast Casserole is incredibly versatile. Here are some ideas to inspire you:

* **Apple Cinnamon:** Add diced apples and a dash of apple pie spice to the custard.
* **Berry Blast:** Mix fresh or frozen berries into the custard and sprinkle them over the bread.
* **Pecan Praline:** Top the casserole with chopped pecans and a drizzle of caramel sauce.
* **Banana Nut:** Add sliced bananas and chopped walnuts to the casserole.
* **Chocolate Raspberry:** Add raspberries and chocolate chips for a rich and fruity twist.
* **Pumpkin Spice:** Use pumpkin puree and pumpkin pie spice in the custard for a festive fall treat.
* **Overnight Oats French Toast Casserole**: If you like overnight oats, you can add oats to the mix. About 1 cup of oats, mixed in with the wet ingredients adds a nice texture.

## Serving Suggestions

This Cinnamon Swirl French Toast Casserole is delicious on its own, but here are some serving suggestions to elevate your brunch:

* **Maple Syrup:** A classic and simple pairing.
* **Fresh Fruit:** Berries, sliced bananas, or peaches add a refreshing touch.
* **Whipped Cream:** A decadent and creamy addition.
* **Bacon or Sausage:** Add a savory element to balance the sweetness.
* **Orange Juice or Mimosas:** A refreshing beverage to complement the casserole.
* **Coffee or Tea:** A warm and comforting drink to complete your brunch.

## Make-Ahead Instructions

One of the best things about this recipe is that it can be made ahead of time. Simply prepare the casserole as instructed, cover it tightly, and refrigerate it for up to 24 hours. When you’re ready to bake, remove it from the refrigerator about 30 minutes before baking to allow it to come to room temperature slightly. Then, bake as directed.

## Storage Instructions

**Q: My casserole is soggy. What did I do wrong?**
A: A soggy casserole may be due to using fresh bread or not refrigerating it long enough. Make sure to use day-old bread and refrigerate it for at least 2 hours before baking.
