It’s pretty easy to make a grilled cheese sandwich, sure. But we here at 12 Tomatoes firmly believe that most things can be improved when transformed into a casserole. And besides, this casserole isn’t just a riff on a grilled cheese, it’s a mashup of the toasty sandwich and a bacon cheeseburger. Which is to say, it’s comfort food that’s not in any way ashamed about its hearty cheesiness. Not even a little bit.
More or less, this is a casserole that’s made up of a dozen little sandwiches with a filling that’s reminiscent of a sloppy joe but flavored like a very cheesy bacon cheeseburger. (Everything about that sounds good, right?) The ingredients maybe aren’t that groundbreaking, but it’s all in the assembly, which goes like this:
You slather six slices of bread with butter, cut them in half, and line the bottom of a baking dish with them, butter side down.
And then you brown up some ground beef and onions but kick up the mixture with ketchup, mustard, mayo, and bacon. It’s all your favorite parts of a burger, there’s just no patty involved.
That gets spread over the slices of bread and topped with two kinds of cheese. (Mozzarella for melting ability and cheddar for flavor.)
Then you top it all off with more buttered bread.
And it all bakes until the bread is toasted and golden brown and the cheese has melted into the hamburger mixture so everything is one very messy but very delicious component. (Go ahead and use a fork – it’s a casserole, after all, not a handheld sandwich.)
INGREDIENTS :
1/2 c margarine
4 c shredded mozzarella and cheddar blend
1/4 c ketchup
1/2 c real bacon bits
1/4 c mayo
1-pound lean ground beef
2 teaspoons onion powder
1 c yellow onion, diced
1 tablespoon mustard
12 slices bread
1/2 teaspoon salt
1/2 teaspoon pepper
DIRECTIONS :
Prepare the oven and preheat it to 200 degrees or 400 degrees F.
Place a skillet on the stove and turn the heat to medium-high. Add butter and allow it to melt.
Add the ground beef into the hot skillet, then cook for a few minutes until crumbly and brown. Remove any accumulated grease that surfaces.
Add the onion, then sauté for a few minutes until translucent.
Remove the skillet from the stove, then add ketchup, salt, pepper, mayonnaise, onion powder, bacon, and mustard. Stir everything until well incorporated.
Spread margarine over the bread slices. Slice each bread slice into two.
Apply cooking spray to the inside of a 9×13-inch baking dish.
Lay the bread slices with the margarine facing down into the prepared baking dish. Top them with cheese.
Add the meat mixture over the bread and cheese. Spread it evenly and top with more cheese.
Top each piece of bread with the rest of the bread slices. Bake for 20 to 24 minutes or until done.
Serve and enjoy!
