Baked Zucchini Casserole

Sharing is caring!

This Easy Baked Zucchini Casserole is one I have been making for years. Made with fresh zucchini and ground beef with just enough spice to make a wonderful dinner idea.

We love cooking with zucchini and the prices for zucchini are great this time of year. This recipe nicely incorporates zucchini and squash for a colorful dinner idea!

Why This Zucchini Casserole Recipe?

Casseroles are so underrated and I love them! While they are popular in the fall and winter, I believe they are good any time of year. My zucchini casserole recipe is easy and is especially great for preparing ahead of time and warming up later.

This is the perfect recipe to combine zucchini and yellow squash. The casserole is colorful and flavorful and I usually do not have leftovers. 

This zucchini casserole recipe is great when you have family members home at different times and need to warm up their dinner later. Everyone can get their own serving of pasta with zucchini and warm it up in minutes.

What I also like is that this casserole does not have canned soup in it. While I certainly do not mind canned soup, I feel that a lot of dishes made with some soups tend to taste similar after a while and they contain more sodium than I would like. You can make this recipe with either green or yellow squash or, both to make it colorful.

Zucchini and mushrooms make this casserole so tasty and healthy!

yellow squash – The yellow squash and zucchini pair perfectly in this recipe. 

onion – I like to use white sweet unions, but you can use any type for this recipe. 

pasta  – I used small shell pasta for this recipe, but you can use any other small pasta.
