Variations

The best thing about this recipe is how simple it is to make. But if you’d like to experiment a little, here are a few ideas for you:

Add crumbled cooked bacon.You can try making this recipe with ground chicken thighs or with ground turkey thighs. It won’t be the same, obviously, but it’s still good. I do recommend using ground thighs and not ground breast, which is very lean.Add your favorite spices, even if they’re not classic cheeseburger seasonings. Smoked paprika and chili powder are very good in this recipe.Mix some sliced pickled jalapenos into the beef mixture before baking it.

To balance out the richness of this cheeseburger casserole, I definitely recommend skipping the starches and serving it with a side veggie, such as simple steamed green beans, roasted asparagus, or a green salad (this arugula salad is excellent).
