Store leftover hamburger and zucchini casserole in glass airtight containers for up to 5 days. If you’re planning on eating this for meal prep, I recommend this glass storage containers.

If you meal prepped this zucchini ground beef casserole in containers like the ones mentioned above, simply remove the lid from the container. Then place the lid on top of the container but not latched on (we need the steam to be able to escape).

Next place in the microwave and cook for 1.5-2 minutes.

If you don’t have a microwave, you can also transfer desired portion to a small skillet and warm up over medium heat for about 5 minutes.

Recipe tips: 

• If you or someone in the family is not a big zucchini fan, then you can always substitute something like yellow squash or eggplant.
• If you want to bulk it up and add more fiber you could add bell peppers or shredded cabbage.
