Betty Crocker’s Cheese Sandwich Casserole

Step-by-Step Instructions

1. The Sandwich Assembly

Lightly grease a 9x13-inch baking dish with a little butter or non-stick cooking spray. Assemble 6 classic cheese sandwiches using the bread and your cheddar cheese. Lay the sandwiches side-by-side in a single layer at the bottom of your baking dish. If needed, you can cut them in half to make them fit snugly like puzzle pieces.

2. Whisk the Custard

In a medium bowl, vigorously whisk together the eggs, whole milk, salt, dry mustard powder, and a pinch of black pepper until the mixture is completely smooth and uniform.

3. The Big Soak

Gently pour the egg and milk mixture directly over the sandwiches, ensuring every single slice of bread gets fully coated.

💡 Betty's Golden Rule

For the absolute best texture, cover the dish and let it sit in the refrigerator for at least 1 hour (or even overnight). This allows the bread to thoroughly drink up the custard all the way to the crusts, preventing dry pockets.

4. Bake to a Golden Puff

Preheat your oven to 350°F (175°C). Just before popping the dish into the oven, drizzle the melted butter over the top of the bread and dust it lightly with the paprika. Bake uncovered for 45 to 50 minutes. You will know it is done when the center is set (it shouldn't jiggle when shaken), the cheese is bubbling, and the top is puffed and golden brown.

Creative Upgrades for the Modern Kitchen

While the purist version is spectacular on its own, this vintage framework is incredibly fun to customize:

• The Diner Classic: Add a slice of smoky deli ham or crisp, cooked bacon inside each sandwich before pouring the custard over top.

• The High-End Upgrade: Swap out standard white sandwich bread for thick slices of brioche or challah, and use a blend of Gruyère and white cheddar.

• The Tomato Soup Companion: Serve this dish with a piping-hot bowl of classic creamy tomato soup on the side for the ultimate nostalgic dipping experience.
