Some nights, I just want something filling that’s simple to throw together and always makes my family happy. This casserole brings all the best bacon cheeseburger and grilled cheese flavors you love into a big pan, all gooey and crisp and golden on top. Everyone at my table digs in with a big grin.
The first time I made this, the whole family couldn’t believe how much it tasted like a real cheeseburger. We kept sneaking back for more! It’s now our go-to for cozy weekends and movie marathons.
Irresistible Ingredients
- Shredded mozzarella and cheddar cheese blend: Delivers the ultimate stretch and richness—grab block cheese and shred for max flavor
- Margarine: Slathered on the bread, it’s the secret to that perfect grilled cheese crunch
- Bread: The sturdy base for all the layers—thick sandwich bread is best so it doesn’t go mushy
- Onion powder: Gives that hint of cheeseburger depth without extra chopping
- Salt and pepper: Because everything tastes better when it’s seasoned right
- Mustard: Kicks up the flavor and makes it taste extra burger-y
- Ketchup: Adds a sweet tang that mimics burger sauce
- Mayo: Creamy magic that holds the filling together and makes it extra tasty
- Real bacon bits: Adds a salty, smoky pop without the extra work
- Yellow onion: Get them sweet and softened—grab ones that feel heavy and look fresh
- Lean ground beef: Juicy but not greasy—pick out a fresh pack with a nice color
Simple Step-by-Step Directions
- Bake it Golden:
- Pop the dish in your already hot oven. Bake about 20 to 24 minutes till you see golden brown bread and bubbles of melty cheese at the edges.
- Add Bread Top:
- Butter up your last six bread slices, cut ‘em in half, and lay them on top with the buttery side facing up. That’s the trick for a crispy golden finish.
- Cheese it Up Again:
- Sprinkle the rest of your cheese mix over the beef so every bite is full of ooey-gooey goodness.
- Spoon on the Meat:
- Evenly spread all your beef mixture across the cheesy bread layer, making sure every corner gets covered.
- First Layer of Cheese:
- Shake half the shredded cheese over the bread—it keeps the bottom nice and gooey while protecting it from getting too soggy.
- Get the Bread Base Ready:
- Spread margarine on one side of six bread slices, cut them in half, and lay them butter-side down along the bottom of a greased 9 x 13 pan.
- Stir in the Flavor:
- Take the pan off heat. Dump in your bacon bits, mayo, ketchup, mustard, salt, pepper, and onion powder. Stir really well so everything is coated nicely.
- Add Onion to Pan:
- Sprinkle in the diced onion with the browned beef, give it a stir, and cook for a few more minutes until the onion softens just a bit but still has some texture.
- Sizzle the Beef:
- In a big skillet, brown the ground beef with a dab of margarine or butter over medium-high. Mash it up as it cooks for even crumbles, and drain off the fat so your casserole isn’t greasy.
- Fire Up the Oven:
- Heat your oven to 400 degrees. That way, things get crispy and bubbly when it’s time to bake.

I love the crispy top bread—the way it toasts up reminds me of a killer grilled cheese. My nephew once said it’s better than any burger he’s had after staying over, and he asks for it every time he visits!
Easy Storage Advice
Once it’s cooled off, move leftovers into a tight-sealed container and stash them in the fridge for up to three days. If you wanna keep it longer, slice it up, wrap it tight, and pop it in the freezer. To get that crispy top again, warm it in a 350 oven—skip the microwave so the bread stays crunchy.
Ingredient Swaps
Feel like switching it up? Use ground turkey or any plant-based meat to lighten things. Any melty cheese is fair game—try Monterey Jack, Colby, or even pepper jack. Want more zip? Toss in some diced pickles or swap BBQ for the ketchup.
Serving Ideas
Ladle out hot squares next to crisp greens or roasted veggies. For that diner feel, throw some pickles on the side or drizzle with special burger sauce. Leftovers pack up well for lunchboxes or picnics, too.
