Cheesy, comforting, and filling, zucchini rice casserole is going to become a favorite around any family table. It’s also a great use for leftover rice!
You know I love my salads as much as the next girl but sometimes you want something more cozy and comforting. Something warm and soft, like a blanket, to wrap around you when you’re having one of those days. Okay, okay, okay, I know we shouldn’t use food to comfort us, but there’s something about the magical combination of cheese and rice that does the trick.
The best part of this zucchini rice casserole, though, is that you’re still eating something nutritious. You’re not drowning those sorrows in an entire chocolate cake or even a burger and fries.
Included in this zucchini rice casserole are the obvious ingredients: zucchini and rice. Summer always leads to plentiful zucchini and this is a great use for it, as is homemade zucchini bread or pizza zucchini noodles.
I like to use brown rice not only for its nutritional value but also because it’s filling, nutty, and flavorful. To speed up the rice cooking time, make the brown rice in your Instant Pot (if you have one).
Then we get to the really good stuff — cheese! I use a mix of Parmesan and sharp cheddar to give this casserole tons of great flavor. Hold everything together with Greek yogurt, sour cream, and eggs.
Zucchini rice casserole would make a great side dish for your Thanksgiving dinner, too! Or even as a main dish for meatless Mondays!
A mix of whole wheat panko bread crumbs (these are the kind I buy) with some herbs, spices, and more Parmesan gives the casserole a crispy crust that seals the deal and makes this recipe a total winner.
More veggie casseroles!
You all know I’m a girl that loves roasted vegetables, but every once in awhile I get down with a casserole like this zucchini rice casserole. Try these recipes:
- 4 cups coarsely grated zucchini, lightly packed (about 1 ¼ pounds)
- ½ cup minced onion
- 2 cups cooked white rice (brown rice is good, too)
- 2 large eggs, lightly beaten
- ½ cup sour cream
- ½ cup 2% plain Greek yogurt
- 1 cup (4 oz.) shredded sharp cheddar cheese (see hint below)
- ¼ cup grated Parmesan cheese, divided
- 1 teaspoon kosher salt
- ½ teaspoon ground black pepper
- ½ teaspoon garlic powder
- 1 teaspoon Italian seasoning, divided
- ¼ cup panko bread crumbs
- Preheat oven to 350°F. Lightly spray a 8x11 inch baking dish with nonstick cooking spray.
- In a large mixing bowl, combine eggs, sour cream, Greek yogurt, cheddar cheese, 2 tablespoons Parmesan cheese, salt, black pepper, garlic powder, ½ teaspoon Italian seasoning. Add shredded zucchini and onions and stir until ingredients are well mixed. Spread mixture into prepared pan.
- In a small bowl, combine breadcrumbs, ½ teaspoon Italian seasoning, and 2 tablespoons Parmesan cheese. Sprinkle evenly over zucchini mixture.
- Bake for 1 hour or until golden brown and heated through.
- If you are using a food processor, shred the cheddar first and set it aside before shredding the zucchini.
- Store leftovers in the refrigerator for up to 4 days. It does not freeze well. Reheat single servings gently in the microwave. Larger quantities can be reheated in the oven. Heat at 350°F for 20 to 30 minutes or until heated through.
- If desired, cooked brown rice, quinoa, farro, or barley can be substituted for the white rice.
- Other types of cheese can be substituted for the cheddar.
- If you like, add cubed ham or cooked bacon to the casserole.
- Crushed Ritz crackers can be substituted for the panko topping, if desired.
