Bacon Cheeseburger Casserole

I saw something like this on Facebook a while back and when I took ground beef out to thaw for dinner this is exactly what I had in mind.  It seemed like a perfect meal for a cold, dreary day for “the boys!”



These are the ingredients, except for the cheese slices because I decided to add them at the last minute.


I started by chopping and cooking the bacon, removing 2 tbsp. of the bacon grease for later and leaving the rest in the pan for the next step.

Once I had removed the grease and bacon from the pan, I added the peeled and sliced onions and cooked them for about 15 minutes until they were browned and softened.


I cut the buns into 1 inch cubes and then mixed them with the reserved bacon grease and set aside.


While the onions were cooking I put the ground beef in a microwave safe bowl and cooked it until it was browned and fully cooked, then drained it.

I mixed in the ketchup and mustard, stirred it to combine and poured it into my prepared pan.



I put the cooked onions on top of the ground beef mixture.


And then the cooked and crumbled bacon.


I sprinkled some grated mozzarella on top of the onions and bacon.


And then this is where I decided to add the slices of cheese.


I topped the cheese with the cubed buns….


And the second amount of cheese.


Then I baked it at 350 degrees for 30 minutes and then switched to broil for what was supposed to be 5 minutes….

Full disclosure here…. I got distracted during the supposed 5 minutes of broil time and didn’t remember until the smoke detector went off letting me know that some of the bread cubes had started to burn 😦

So… I scraped off the worst of the burned part and added more grated mozzarella to try to hide and remaining burned bread lol!  I put it back in the oven…. not on broil lol… just long enough to remelt the cheese!

Chris told me the burned part just gave it a bit more flavour!


I cut it into squares and served it to the boys!

  1. That looks so delicious. I’ve been on a caramelized onion, ketchup, and mustard with hamburger kick myself. But I’m afraid my concept is really fattening. I’ve been addicted to making myself patty melts, which are like a hybrid grilled cheese hamburger, with plenty of butter on the bread. I cut it in half and dip in ketchup and mustard. I think blending some Worcestershire into the meat before cooking it would really make all the other flavors in this shine. You could also try Balsamic vinegar for a different, lemony sweet effect. Both will really accentuate the bacon nicely.

    • I really like the Worcestershire sauce idea. It would give it a bit more kick.
      I appreciate your plight, when you find something good, it’s really hard not to continually enjoy it lol! And your patty melt sounds divine! A real shame for me that I can’t eat “meat,” my melts pretty much extend only to tuna. Still good but nowhere near as good as yours sound!!!

      • I do the same thing some time, but fortunately you can always add another comment. It’s like a conversation so you get caught up in the ideas and forget the formalities. You’re so welcome! As for the tuna melts, I can’t do cheese and fish together, but I LOVE tuna casserole. I also have to limit my red meat intake and I’ve been very naughty with the patty melts. I should only eat red meat once a week and between last week and this week I’ve eaten a total of 6 patty melts. Chicken pork seafood eggs for two weeks for me! But beef is a favorite. wwwwaaaaaaaaaaaaaaaaaaaaaa

      • Lol. Sometimes I forget everything, especially here. Like you said, it is a conversation whether online or not and sometimes you do forget the formalities trying not to forget to respond to something else!
        There are days I would give almost anything for a nice juicy burger but have learned to know better. I do, on occasion, engage in that naughty behavior but that just reminds me why I don’t eat it 😔
