Why We Love It

I’m obsessed with zucchini this summer. Almost every week I’m picking some up from my local farm stand. I love it grilled, crisped and air fried, in baked goods and in salads like Creamy Avocado Zucchini Salad and Zucchini Slaw.

But one area that was lacking in my zucchini arsenal was a wholesome, tasty side dish. Though most consider it a vegetable, zucchini is one of those fruits that lingers in the shadows at times. It doesn’t have much taste on its own, but it always delivers a pretty color vibe and a ton of nutrients and moisture in whatever lucky recipe it’s included in.

How then, could zucchini be included in a tasty side dish? And what, exactly, could it be partnered with to bake well in the oven?

If you know me at all, you probably figured I was going to mention cheese at some point. C’mon, of course it was one of the first things I thought of! Tangy extra sharp cheddar almost immediately came to mind. Then the image of that oozing, melted cheddar started making me think about rice and noodles. Rice was the surefire winner for this recipe because it can readily absorb moisture and flavor quite easily.

Let’s just say there was a lot of playing around with these ingredients and that I have a very patient family (they were at least eating cheese each time and that certainly helped)! What eventually came out of all this taste testing/trial and error was one heck of a savory dish.

Cheesy Rice Zucchini Casserole checks off all the boxes here. Gooey, cheesy, savory and wholesome–with some great nutrients hiding inside–this tasty dish is the perfect companion to every meat we eat (especially chicken and turkey). It can also stand all on its own as a main course!

Why You’ll Love It

Feeds a crowd- This recipe makes a lot. I usually get two meals out of this for my family of four when it’s served as a side. Because it bakes in a 13×9 pan, it’s also an excellent choice for a larger gathering or holiday meal.

Pairs well with many proteins- Because of its great taste and mounds of cheese, this side is an excellent companion to ham, poultry, pork and fish.

Packed full of nutrients- Did you know that zucchini has an incredible amount of potassium and Vitamin C? You’ll also get a hefty serving of protein and calcium from the cheese in this dish!

Stores well- Cheesy Rice Zucchini Casserole keeps well in the fridge, and can also be frozen.

Cheesy Rice Zucchini Casserole Ingredients

  • 2 pounds (about 3 medium) zucchini
  • 1 & 1/2 cups cooked rice
  • 2 cups extra sharp cheddar cheese, grated

  • 1/4 cup extra virgin olive oil
  • 1 egg, slightly beaten
  • 1/4 teaspoon dried rosemary
  • dash of salt (for zucchini pot)

How to make Cheesy Rice Zucchini Casserole

You’ll want to gather the following equipment:

  • large pot with lid (for the zucchini)
  • medium pot with lid (for the rice)
  • cheese grater
  • 13×9 glass baking dish
  • cutting board
  • santoku or chef’s knife

  • measuring spoons
  • mixing spoon or wooden salad spoons
  • spatula (for serving)

Getting Started

Preheat oven to 350 degrees

To get started, cook whole zucchini in salted, boiling water until just tender. This usually takes about 15 minutes (check with a fork periodically).

While the zucchini is cooking:

  • cook rice according to package directions
  • grate the cheese
  • chop the parsley
  • dice the green onions

Kitchen Ready Betty tip: Once the zucchini is chopped, absorb excess water with paper towels while it sits in the colander. You don’t want to add overly moist zucchini to the casserole because it will make the consistency too mushy.

adding rice to the bowl

Once properly drained, place the diced zucchini in a large bowl. Add green onions and parsley. Then add the cooked rice and gently mix.

Next, add the rosemary and grated cheese. Gently mix.

Once zucchini is tender, drain in colander and let cool. Then chop cooled zucchini into bite-sized pieces. Drain once more.

Drizzle on the olive oil and add the slightly beaten egg. Stir to combine.

spreading cheesy rice zucchini casserole into pan

Place mixture in a lightly greased 13×9 glass baking dish. Spread the mixture with a spoon to evenly cover the bottom of the dish. Bake uncovered in a 350 degree preheated oven for 45-50 minutes, or until casserole is slightly brown around the edges and center is somewhat firm.

Storing Cheesy Rice Zucchini Casserole

Refrigerate, store in an airtight container and enjoy within 5 days.

You may also freeze leftovers in freezer safe packaging for up to 3 months. Defrost overnight in fridge when ready to enjoy.

To reheat, cover with aluminum foil and bake at 325 degrees for 20-25 minutes or until heated through.

Because chicken is so good with this, sometimes I’ll add leftover chicken with a little bit of chicken broth to the leftover Cheesy Rice Zucchini Casserole. I sprinkle it with a little extra cheese and bake it all together at 325 degrees for 20 minutes, then uncover it and bake it for another 5 minutes. It’s a great way to use up two leftovers at once and it tastes great!

Note

I sometimes use pre-shredded cheese, but this (and all dishes) tastes so much better when you grate the cheese yourself.

You may use any variety of rice, including instant or brown. I often use long grain white rice, but any option will work. Just remember to cook it first!

Fresh parsley adds an aromatic flavor, but if that's not for you, simply omit it!

Some food for thought....

Expand All:
Why can't I just shred the zucchini?

It's true that a lot of recipes use shredded. We cook the zucchini whole first to get it tender to cut down on bake time. Then we dice it, drain it and remove a lot of excess moisture before it gets mixed with the other ingredients.

Can I swap out the olive oil for chicken broth?

There's not a lot of olive oil in this recipe, but it gives the casserole more of a savory flavor, along with the rosemary. I would not substitute it.

Do you skin the zucchini?

Nope. After it boils, its texture is very edible. It gives color to this dish as well as added nutrients!
