Tips for the Best Results
- Be sure to drain excess fat from the cooked ground beef to prevent a soggy casserole.
- Slice the zucchini into uniform pieces for even cooking.
- Use your favorite type of cheese for the topping, such as sharp cheddar cheese or parmesan cheese.
- Allow the casserole to cool slightly for a few minutes before serving to allow the flavors to meld together.
- Change up the cheese for a slightly different flavor each time!
- If you don't have cilantro, you can use 1 teaspoon of coriander as a substitute (it’s the dried seed of the cilantro).
- Make this the night before so it is ready to serve when you are.
- You can throw a few crushed Ritz crackers or panko bread crumbs on top before baking if you like.
- Top with crushed red pepper flakes for a bit of a kick.
- Dry your zucchini slices with paper towels to remove extra moisture before cooking to avoid having too much liquid in your casserole.

- Add diced tomatoes or bell peppers for extra flavor and nutrition.

Yes, anything with noodles is my kind of meal!

So perfect to use up the zucchinis in my garden. This casserole will be a great dish to make for my neighbor who just had a baby.
Barb
What size casserole and what kind of shredded cheese do you use?
Raquel
I use a 13 x 9 inch rectangle or oval dish. A Cheddar and Monterey Jack combination works wonderfully with this!
Vicki
Am I just missing it or are the mushrooms left out of the recipe?
Raquel
Thanks Vicki! They are not in the recipe and were listed by accident.

We are big zucchini fans and loved this recipe. Thanks for posting it.

As I was throwing this together I was skeptical. I used what I had on hand so instead of chilis I did diced tomatoes and added mushrooms. I didn’t have cilantro either. All I can say is this turned out incredible!!! Oh yeah, and garlic. Lots of chopped garlic to the zucchini and onion medley while it was cooking. This one is a keeper, thank you for sharing!!! Husband approved too 😉
