## Ingredients You’ll Need

Here’s a detailed list of the ingredients you’ll need to create this delectable Overnight Bacon Brunch Casserole:

* **1 pound bacon:** Opt for thick-cut bacon for maximum flavor and crispiness. You can use your favorite brand or variety.
* **1 loaf (about 1 pound) of bread:** Choose a sturdy bread that can hold its shape well. French bread, sourdough, or even a hearty Italian bread work beautifully. Stale bread is actually preferable, as it soaks up the custard better without becoming mushy. You can even leave your bread out overnight to dry it out a bit.
* **6 large eggs:** These form the base of the custard and provide richness and structure to the casserole.
* **2 cups milk:** Whole milk is recommended for the creamiest texture, but you can use 2% milk if you prefer.
* **1 cup shredded cheddar cheese:** Sharp cheddar provides a nice tangy flavor that complements the bacon. You can also use a blend of cheddar and Monterey Jack or Gruyere for a more complex flavor.
* **1/2 cup shredded mozzarella cheese:** This adds a gooey and melty texture to the casserole.
* **1/4 cup chopped green onions:** These add a fresh and slightly oniony flavor that brightens up the dish. You can substitute with chives if you prefer.
* **1 teaspoon Dijon mustard:** This adds a subtle tang and depth of flavor to the custard.
* **1/2 teaspoon salt:** Enhances the flavors of all the ingredients.
* **1/4 teaspoon black pepper:** Adds a touch of spice and balances the richness of the casserole.
* **Optional additions:**
* **Cooked and crumbled sausage:** Add another layer of savory goodness.
* **Diced vegetables:** Onions, bell peppers, mushrooms, or spinach can be added for extra flavor and nutrients.
* **Hot sauce:** A few dashes of your favorite hot sauce can add a kick of heat.
* **Fresh herbs:** Parsley, thyme, or rosemary can be added for a touch of freshness.

## Equipment You’ll Need

* **9×13 inch baking dish:** This is the ideal size for this casserole. A ceramic or glass baking dish works best.
* **Large skillet:** For cooking the bacon.
* **Mixing bowls:** For preparing the custard and combining the ingredients.
* **Whisk:** For whisking the custard until smooth.
* **Cutting board:** For chopping the bread and vegetables.
* **Knife:** For chopping the ingredients.
* **Measuring cups and spoons:** For accurately measuring the ingredients.
* **Aluminum foil (optional):** To cover the casserole during baking if the top is browning too quickly.

## Step-by-Step Instructions

Now, let’s get to the heart of the matter: creating this amazing Overnight Bacon Brunch Casserole.

**Preparation (Night Before):**

1. **Cook the Bacon:** In a large skillet over medium heat, cook the bacon until crispy. Drain the bacon on paper towels and then crumble or chop it into bite-sized pieces. Set aside.
2. **Prepare the Bread:** Cut the bread into 1-inch cubes. You can leave the crusts on or remove them, depending on your preference.
3. **Grease the Baking Dish:** Generously grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the casserole from sticking to the dish.
4. **Layer the Ingredients:** Arrange half of the bread cubes in the bottom of the prepared baking dish. Sprinkle half of the cooked bacon, cheddar cheese, mozzarella cheese, and green onions over the bread. Repeat the layers with the remaining bread, bacon, cheeses, and green onions.
5. **Prepare the Custard:** In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until smooth and well combined.
6. **Pour the Custard:** Slowly and evenly pour the custard mixture over the bread and bacon layers in the baking dish. Gently press down on the bread to ensure that it’s fully submerged in the custard.
7. **Cover and Refrigerate:** Cover the baking dish tightly with plastic wrap or aluminum foil and refrigerate overnight (or for at least 8 hours). This allows the bread to soak up the custard and the flavors to meld together.

**Baking (The Next Morning):**

1. **Preheat the Oven:** Preheat your oven to 350°F (175°C).
2. **Remove from Refrigerator:** Take the baking dish out of the refrigerator about 30 minutes before baking. This allows the casserole to come to room temperature slightly, which will help it bake more evenly.
3. **Bake the Casserole:** Remove the plastic wrap or aluminum foil from the baking dish. Bake the casserole in the preheated oven for 45-55 minutes, or until the top is golden brown and the custard is set. A knife inserted into the center of the casserole should come out clean.
4. **Check for Browning:** If the top of the casserole starts to brown too quickly, you can loosely cover it with aluminum foil during the last 15-20 minutes of baking.
5. **Let it Rest:** Once the casserole is done, remove it from the oven and let it rest for 10-15 minutes before serving. This allows the custard to set completely and makes it easier to slice.

## Serving Suggestions

This Overnight Bacon Brunch Casserole is delicious on its own, but here are some serving suggestions to elevate your brunch experience:

* **Fresh Fruit Salad:** A colorful fruit salad with berries, melon, and grapes provides a refreshing contrast to the richness of the casserole.
* **Yogurt Parfaits:** Layer yogurt, granola, and fresh fruit in glasses for a light and healthy side dish.
* **Orange Juice or Mimosas:** A classic brunch beverage that complements the flavors of the casserole.
* **Coffee or Tea:** The perfect accompaniment to a leisurely brunch.
* **Maple Syrup:** Drizzle a little maple syrup over individual slices of the casserole for added sweetness.
* **Hot Sauce:** Offer a variety of hot sauces for those who like a little kick.
* **Sour Cream or Salsa:** A dollop of sour cream or a spoonful of salsa can add a creamy and tangy element to the dish.

## Tips for Success

* **Use Stale Bread:** As mentioned earlier, stale bread works best in this recipe because it soaks up the custard better without becoming mushy. If you don’t have stale bread, you can dry out fresh bread by leaving it out overnight or toasting it lightly in the oven.
* **Don’t Overcook the Bacon:** Cook the bacon until it’s crispy but not burnt. Burnt bacon will have a bitter taste that will affect the overall flavor of the casserole.
* **Whisk the Custard Well:** Make sure to whisk the custard ingredients together thoroughly until they are smooth and well combined. This will ensure that the custard bakes evenly.
* **Press Down on the Bread:** When you pour the custard over the bread and bacon layers, gently press down on the bread to ensure that it’s fully submerged in the custard. This will help the bread soak up the custard properly.
* **Adjust Baking Time as Needed:** The baking time may vary depending on your oven. Check the casserole after 45 minutes and adjust the baking time as needed until the top is golden brown and the custard is set.
* **Let it Rest Before Serving:** Allowing the casserole to rest for 10-15 minutes before serving is crucial. This allows the custard to set completely and makes it easier to slice.
* **Experiment with Flavors:** Don’t be afraid to experiment with different flavors and ingredients. Add cooked sausage, diced vegetables, hot sauce, or fresh herbs to customize the casserole to your liking.

## Variations

The beauty of this Overnight Bacon Brunch Casserole lies in its versatility. Here are a few variations to inspire your creativity:

* **Sausage and Cheese Casserole:** Substitute the bacon with cooked and crumbled sausage for a different flavor profile. Use a blend of cheddar and Monterey Jack cheese for a milder flavor.
* **Vegetarian Casserole:** Omit the bacon and add diced vegetables such as onions, bell peppers, mushrooms, and spinach. Use a blend of cheddar and Gruyere cheese for a more complex flavor.
* **Spicy Casserole:** Add a few dashes of your favorite hot sauce to the custard for a kick of heat. You can also add diced jalapeños to the bread and bacon layers.
* **Mediterranean Casserole:** Add sun-dried tomatoes, olives, and feta cheese to the bread and bacon layers. Use oregano and basil instead of green onions.
* **Ham and Swiss Casserole:** Substitute the bacon with diced ham and use Swiss cheese instead of cheddar and mozzarella.

## Storage Instructions

* **Refrigerate:** Leftover Overnight Bacon Brunch Casserole can be stored in the refrigerator for up to 3 days. Cover the casserole tightly with plastic wrap or aluminum foil to prevent it from drying out.
* **Reheat:** To reheat the casserole, preheat your oven to 350°F (175°C). Place the casserole in the oven and bake for 15-20 minutes, or until heated through.
* **Freeze:** You can also freeze the casserole for longer storage. Cut the casserole into individual slices and wrap each slice tightly in plastic wrap and then in aluminum foil. Freeze for up to 2 months. Thaw the casserole in the refrigerator overnight before reheating.
