I have one more recipe for all you gardeners with a zucchini surplus. This time, I combined the zucchini with ground beef to make a casserole.
Because we all need easy dinner recipes for busy weeknights!
And, when you can make something with delicious traditional flavors but make it a little more healthy, it feels like such a win!
No simple carbs, just lots of veggies and burger.
My 2 favorite words: easy and cheesy!
🥘 Ingredients
I had a couple priorities with this casserole. Keep it low carb was one, so that means no rice or pasta. I also wanted to avoid using a can of soup, but still wanted a simple ingredient list. I was delighted when I was able to accomplish all these goals.
The primary ingredients are of course ground beef and zucchini. The “sauce” is a can of diced tomatoes and a half can of tomato paste.
To give the dish a little Italian flavor, I add onion, garlic, Italian seasonings and, of course, cheese. Because there’s no such thing as too much cheese!
How to make this Ground Beef Zucchini Casserole
Start by browning the onions and ground beef. While that is browning, I like to slice up the zucchini. With a good food processor this is about a one-minute job, but it can certainly be done by hand. Just try to get the slices as evenly thin as possible so they all cook at the same speed.
Once the meat is brown, add the garlic and seasonings. Then add the can of diced tomatoes, the tomato paste, and water. Mix well to make a sauce and to fully incorporate the meat. Simmer this mixture for about 10 minutes.
Mix in the zucchini and Parmesan cheese, then transfer to a casserole dish.
Top with shredded cheese, cover and bake for 30 minutes, then uncover and bake for 10-15 minutes more. Allow to rest for 10-15 minutes before serving.
🍲 How to Serve this Casserole
Because the zucchini will release water when heated, this does end up being a little “soupy” in texture. It makes a fantastic bowl meal!
I eat it just as is, to keep my carbs in check. But it is also great with a side of rice or noodles (or zoodles!) if you want to round out the meal a little more.
If you want less liquid in the casserole, you could bake uncovered for the whole time to promote evaporation. Use a larger (deeper!) casserole dish for this to minimize the sauce from bubbling too much and making a mess in the oven!
Alternatively, if you use a large oven safe skillet for the browning and mixing steps, you can just leave the mixture in the skillet, cover in cheese, and bake the casserole right in the skillet. Fewer dishes- always a win. 😃
If desired, you could also finish with a few minutes under the broiler to brown the cheese on top. Browned cheese . . . mmm.
You’ll want to make this easy casserole a regular in your meal rotation!

Frequently Asked Questions
Absolutely! Ground turkey or chicken can be used as a leaner alternative to ground beef. Just adjust the cooking time accordingly, especially when browning, as these meats tend to cook faster.
You can easily prepare the casserole and refrigerate it for up to 24 hours before baking. This makes it a convenient option for meal prepping, especially for busy weeknights.

I had on hand...ground beef, zucchini and summer squash, Parmesan cheese. Put that into a search, and tried this recipe as I had all other ingredients but the Italian blend shredded cheese, so sent the hubby to pick that up on his way home from school. This was so tasty, and enough left for a second meal for the two of us. I haven't done a zucchini casserole in years and years. Thank you!
