For a cheesier topping to your casserole, add in parmesan cheese in addition to cheddar.
If your casserole gets dry when reheating, try using chicken broth or a cup of butter (melted) to rehydrate it before cooking.
Save on prep time with frozen, pre-cut green beans as opposed to room temperature whole petite green beans. The same goes for using drained beans instead of fresh to save time, if frozen aren’t available.
Be sure to drain the beans to keep the casserole from being watery. Put the drained green beans on paper towels to remove excess water.
Want a little sweetness? Add a tablespoon of brown sugar to the mix!
For the crispiest bacon, choose packaged thick-sliced bacon, and cook on aluminum foil before removing from the heat and patting off extra bacon grease.
