Ingredients:
- 1 loaf (1 pound) day-old Italian bread, cut into 1-inch cubes
- 8 ounces cream cheese, softened
- 1/2 cup mayonnaise
- 1/4 cup milk
- 1 teaspoon Dijon mustard
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
- 1 pound sliced deli ham, chopped
- 1 pound sliced cheddar cheese, shredded (about 4 cups)
- 1/2 cup butter, melted
- 1 tablespoon poppy seeds
- 1 tablespoon dried minced onion
Preparing the Bread and Cheese Mixture
Okay, let’s get started! The first thing we need to do is get our bread ready. Using day-old bread is key here because it soaks up the cheesy goodness without getting too soggy. If your bread is super fresh, you can lightly toast the cubes in a low oven (around 200°F) for about 15-20 minutes to dry them out a bit.
- Cube the Bread: Cut the loaf of Italian bread into 1-inch cubes. Aim for relatively uniform sizes so they bake evenly. Don’t worry about being perfect; a little variation is fine.
- Prepare the Cream Cheese Mixture: In a large bowl, combine the softened cream cheese, mayonnaise, milk, Dijon mustard, garlic powder, and black pepper. Make sure the cream cheese is really soft; otherwise, you’ll end up with lumps. You can even microwave it for 15-20 seconds to soften it further, but be careful not to melt it.
- Mix the Wet Ingredients: Use an electric mixer (handheld or stand mixer) to beat the ingredients together until smooth and creamy. If you don’t have a mixer, you can use a whisk, but it will take a bit more elbow grease. The mixture should be easily spreadable.
- Combine Ham and Cheese: In a separate bowl, combine the chopped ham and shredded cheddar cheese. Make sure the ham is chopped into bite-sized pieces so it distributes evenly throughout the casserole.
- Combine Bread and Cheese Mixture: Add the cubed bread to the bowl with the cream cheese mixture. Gently toss everything together until the bread is evenly coated. Be careful not to crush the bread cubes. You want them to be nicely coated but still hold their shape.
- Add Ham and Cheese to Bread Mixture: Now, add the ham and cheese mixture to the bread mixture. Again, gently toss everything together until well combined. Make sure the ham and cheese are distributed evenly throughout the bread.
Assembling the Casserole
Now that we have our bread mixture ready, it’s time to assemble the casserole. This part is super easy, and you’re almost there!
- Prepare the Baking Dish: Grease a 9×13 inch baking dish with cooking spray or butter. This will prevent the casserole from sticking and make it easier to serve.
- Pour the Mixture into the Dish: Pour the bread mixture into the prepared baking dish and spread it out evenly. Gently press down on the mixture to pack it slightly.
Preparing the Topping
The topping is what really makes this casserole special. It adds a buttery, savory crunch that complements the cheesy interior perfectly.
- Melt the Butter: In a small bowl, melt the butter. You can do this in the microwave or in a saucepan on the stovetop. If using the microwave, heat it in 30-second intervals, stirring in between, until melted.
- Add Poppy Seeds and Onion: Add the poppy seeds and dried minced onion to the melted butter and stir to combine. This mixture will give the casserole a lovely flavor and texture.
- Pour Topping over Casserole: Pour the melted butter mixture evenly over the top of the casserole. Make sure to drizzle it all over so that every part of the top gets a nice coating.
Baking the Casserole
Finally, it’s time to bake our masterpiece! The baking time is crucial to ensure the casserole is heated through and the top is golden brown and bubbly.
- Preheat the Oven: Preheat your oven to 350°F (175°C). Make sure your oven is fully preheated before putting the casserole in.
- Bake the Casserole: Bake the casserole for 30-40 minutes, or until it is golden brown and bubbly. The exact baking time will depend on your oven, so keep an eye on it. If the top starts to brown too quickly, you can loosely cover it with aluminum foil for the last 10-15 minutes of baking.
- Let it Rest: Once the casserole is done, remove it from the oven and let it rest for 5-10 minutes before serving. This allows the casserole to set up a bit and makes it easier to cut and serve.
Serving Suggestions
This Cheese Sandwich Casserole is delicious on its own, but it also pairs well with a variety of sides. Here are a few suggestions:
- Salad: A simple green salad with a vinaigrette dressing is a great way to balance out the richness of the casserole.
- Soup: A bowl of tomato soup or creamy vegetable soup would be a comforting addition to the meal.
- Fruit: A side of fresh fruit, like berries or melon, can add a refreshing touch.
- Vegetables: Steamed broccoli, green beans, or asparagus are healthy and delicious options.
Tips and Variations
Want to customize your Cheese Sandwich Casserole? Here are a few ideas:
- Cheese Variations: Feel free to experiment with different types of cheese. Gruyere, Swiss, or Monterey Jack would all be delicious. You can also use a combination of cheeses for a more complex flavor.
- Meat Variations: Instead of ham, you can use turkey, roast beef, or even cooked sausage.
- Vegetable Additions: Add some chopped vegetables to the bread mixture, such as bell peppers, onions, or mushrooms.
- Spice it Up: Add a pinch of red pepper flakes to the cream cheese mixture for a little heat.
- Make it Ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Just add the topping right before baking.
Storage Instructions
If you have any leftovers (which is unlikely!), you can store them in the refrigerator for up to 3 days. Reheat the casserole in the oven or microwave until heated through.
