Easy Cheesy Zucchini Casserole (2 Ingredients!)

Today I’m excited to share one of the simplest recipes in my collection — an easy, cheesy zucchini casserole made with just 2 basic ingredients. All you need is fresh shredded zucchini and your favorite cheese to create a light, healthy, and incredibly satisfying dish.

What I love most is that this casserole is not only quick and budget-friendly, but also Weight Watchers friendly. Each serving is low in calories and WW Points, so you can enjoy cheesy comfort food without getting off track.

The zucchini bakes up tender, the cheese melts into gooey perfection, and the end result works just as well as a side dish as it does a vegetarian main. I sometimes add garlic, a pinch of salt and pepper, or even experiment with other vegetables for fun variations. However you make it, this casserole has become one of my go-to WW zucchini recipes.

Why You’ll Love This Easy Zucchini Recipe

• Just 2 ingredients – Fresh zucchini and cheese are all you need for a simple, delicious dish.
• Weight Watchers friendly – Low in calories and WW Points, this casserole is an easy way to enjoy comfort food while staying on track.

• Flexible with ingredients – Add garlic, swap in different cheeses, or even try other vegetables to keep things interesting.
• Perfect for zucchini season – When gardens and markets are overflowing, this recipe is an easy way to use them up without fuss.

Ingredients & Substitutions

• Zucchini – Shredded fresh zucchini is the base of this casserole. Green, yellow, or striped varieties all work, and you can mix them for color.

How to Make this Easy Healthy 2-Ingredient Shredded Cheesy Zucchini Casserole

Step 1: Prep the oven, pan and ingredients

Preheat your oven to 350°F. Lightly spray an 8-inch baking or gratin dish with nonstick spray. You can use a food processor (affiliate link) to shred your zucchini or an old fashioned box grater (affiliate link).

Step 2: Combine ingredients

In a large mixing bowl (affiliate link), add the shredded zucchini, cheese, optional garlic, salt, and pepper. Stir well until everything is evenly combined.

Step 3: Transfer to baking dish

Spoon the mixture into the prepared pan, spreading it evenly.

Step 4: Bake

Place the dish in the oven and bake for about 30 minutes, or until the casserole is golden and bubbling.

Step 5: Serve

Remove from the oven and let cool slightly. Serve hot or at room temperature.

Recipe Notes & Serving Suggestions

Zucchini tips – Green, yellow, or striped zucchini all work. Use whichever you have on hand.

Cheese options – Any good melting cheese (cheddar, mozzarella, Swiss, provolone, Monterey Jack, etc.) will be delicious. To save WW Points, go with reduced-fat cheese.

Texture – Be sure to squeeze out excess liquid from the shredded zucchini if it seems watery; this helps keep the casserole firm.

Serving ideas – This casserole pairs well with chicken, fish, pork, or beef. It can also stand alone as a vegetarian main dish with a side salad and a slice of crusty bread.

Leftovers – Store covered in the fridge for up to 3 days. Enjoy cold, warmed in the microwave (affiliate link), or even crumbled over a salad for extra flavor.
