I love how a pile of simple veggies and rice turns into a hearty, colorful casserole that feels way more satisfying than the effort suggests. This is the kind of weeknight dinner that makes meatless look seriously irresistible.

I’m obsessed with this Veggie Rice Casserole because it tastes like my weeknight brain finally got its act together. The whole pan turns savory and satisfying, the edges get a little cheesy, and every bite has that loaded veggie thing I want when dinner needs to feel legit without a production.

I love how zucchini keeps it fresh while kale brings that slightly earthy bite that makes everything feel balanced. And yes, I absolutely go back for the corner pieces first.

But the best part? It tastes like I tried harder than I did.

Big dinner energy, minimal drama.

Print Recipe (No Advertisments)

1. Preheat oven to 375 F and lightly oil a 9×13 inch baking dish.

2. In the baking dish combine 1 cup rinsed long grain white rice and 2 1/2 cups low sodium vegetable broth.

3. Add 1 medium diced zucchini, 2 medium diced tomatoes or 1 1/2 cups halved cherry tomatoes, and 2 cups chopped kale (stems removed) into the dish.

4. In a small bowl or measuring cup stir together 1 small finely chopped yellow onion, 2 cloves minced garlic, 2 tablespoons extra virgin olive oil, 1 teaspoon kosher salt, 1/2 teaspoon freshly ground black pepper, 1 teaspoon dried oregano, and 1 teaspoon dried basil; pour over the rice and vegetables.

5. Gently stir everything in the dish to evenly distribute vegetables and seasonings, scraping any rice from the bottom so it is submerged in broth.

6. Cover the dish tightly with foil and bake for 35 to 40 minutes until the rice is tender and most liquid is absorbed.

7. Remove foil and sprinkle 1 cup shredded mozzarella or mild cheddar and 1/4 cup grated Parmesan over the top. If using, evenly sprinkle 1/2 cup plain breadcrumbs or panko.

8. Return to the oven, uncovered, and bake 8 to 10 minutes more until cheese is melted and breadcrumbs are golden.

9. Let rest 5 to 10 minutes before serving so the casserole sets.

10. Sprinkle 1 tablespoon chopped fresh parsley over the top as a garnish and serve hot.

FAQ

Q: How long and at what temperature should I bake this casserole? A: Preheat oven to 375 F. Cover and bake for about 35 to 40 minutes until rice is tender and liquid is absorbed, then uncover, sprinkle with mozzarella and Parmesan and breadcrumbs if using, and bake another 8 to 12 minutes until cheese is melted and topping is golden.

Q: Can I use brown rice instead of long grain white rice? A: Yes, but use 2 cups of broth and increase the covered bake time to about 55 to 65 minutes, or cook the brown rice separately and add it near the end to avoid overcooking the vegetables.

Q: Will the tomatoes make the casserole watery and how do I prevent that? A: To avoid excess liquid, use diced firm tomatoes or halved cherry tomatoes and gently drain very juicy tomatoes, or stir them in partway through baking so they do not release too much liquid early on.

Q: Can I make this ahead or freeze it? A: You can assemble and refrigerate for up to 24 hours before baking. Once baked, store leftovers in the refrigerator for 3 to 4 days or freeze in an airtight container for up to 2 months. Reheat from frozen in a 350 F oven covered until hot, then uncover to crisp the topping.

Q: How can I make this dairy free or vegan? A: Substitute vegan shredded cheese and vegan Parmesan, or omit the cheeses and sprinkle with nutritional yeast for a savory note. Use olive oil for the topping and crisp with breadcrumbs or panko if desired.

Q: What good vegetable or seasoning substitutions work well? A: Swap zucchini for yellow squash, add bell peppers, mushrooms, or frozen peas. Fresh herbs like basil or thyme work well, and a squeeze of lemon or a pinch of red pepper flakes can brighten the flavor.

Veggie Rice Casserole Recipe Substitutions and Variations

1 cup long grain white rice: Substitute with 1 cup brown rice for nuttier flavor and more fiber; increase broth to 3 cups and bake 15 to 20 minutes longer. Or use 1 cup quinoa for a protein boost and slightly shorter bake time.
2 1/2 cups low sodium vegetable broth: Substitute with low sodium chicken broth for a richer savory base, or use 2 1/2 cups water plus 1 teaspoon bouillon or miso paste for umami without added sodium.
2 cups chopped kale: Substitute with 2 cups baby spinach or Swiss chard, added toward the end of cooking if very tender, or use 2 cups chopped collard greens for a heartier texture.
1 cup shredded mozzarella or mild cheddar: Substitute with Monterey Jack or fontina for good melt and mild flavor, or use 1 cup crumbled feta for a tangier finish and slightly saltier profile; reduce added salt if using feta.

Pro Tips

1. Brown the onion and garlic briefly in the olive oil before adding them to the dish to build deeper flavor and avoid any raw bite from the onion after baking.
2. If your zucchini releases a lot of water, salt it lightly and let it sit in a colander for 10 minutes, then pat dry. That keeps the casserole from becoming too watery and concentrates the veg flavors.
3. For an extra creamy rice texture, check for doneness a few minutes before the stated time. If it is almost done but still a touch firm, let it rest covered for 10 minutes off heat to finish steaming rather than adding more liquid.
4. Make the topping more interesting: toss the breadcrumbs or panko with a little olive oil, grated Parmesan, and lemon zest before sprinkling. It will brown more evenly and add a bright finish to the casserole.
