Zucchini Herb Casserole

Sharing is caring!

This Zucchini Herb Casserole is a favorite recipe of ours. It’s a fast and easy side dish for any meal. It’s perfect for summertime when your garden is overflowing with zucchini, or for when you become the victim of a gardener who continues to give you their extra zucchini.

To make this recipe even easier for those extra busy summer nights, I always keep a few bags of cooked rice in the freezer for recipes like this. Canned tomatoes work in place of fresh tomatoes to help you skip the chopping! I can pull this recipe together in about 10 minutes and have it in the oven while I grill up some chicken or make burgers.

The whole family really enjoys this recipe and I’ve been asked for it several times, which is why it made the cut to be featured on the blog. I hope you find this recipe delicious and try it out soon!

Zucchini side dish

Zucchinis are a super inexpensive and nutrient-rich vegetable that make them the perfect addition to your meal plans! This recipe is great for a barbecue and goes perfect with grilled chicken, beef roast, pulled pork sandwiches, and burgers. I love that I can make it the night before and just warm it up before dinner. It mixes both your veggies and carbohydrates so it makes the perfect side dish.

Looking for an easy way to make this side dish a complete meal? Just add in some sliced up smoked sausage before you bake and voila! you have a quick and easy one-dish meal. You could also add in some cooked chicken, even shrimp or salmon would be amazing in this casserole! I love finding a versatile recipe that we can make several different ways!
