Ingredients
- 1 cup uncooked white rice
- 2 cups vegetable broth (or chicken broth for non-vegetarian)
- 10 oz fresh spinach, chopped
- 1 cup shredded cheddar cheese
- 1/2 cup onion, finely diced
- 2 cloves garlic, minced
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- 1/2 teaspoon ground cumin
- 1 teaspoon dried oregano
- 1/2 teaspoon fennel seeds (optional)
- 1 tablespoon lemon zest (for freshness)
- 2 tablespoons olive oil
- Salt and pepper to taste
Step-by-Step Instructions
- Cook the rice: In a saucepan, combine rice and vegetable broth. Bring to a boil, then reduce heat, cover, and simmer for 15-18 minutes or until rice is tender and liquid is absorbed. Set aside.
- Prepare the vegetables: Heat olive oil in a skillet over medium heat. Add diced onion and sauté for 3-4 minutes until soft. Add minced garlic and cook for 1 minute until fragrant.
- Add spinach and spices: Add chopped spinach to the skillet and cook until wilted, about 2-3 minutes. Stir in garlic powder, smoked paprika, ground cumin, dried oregano, and fennel seeds (if using). Season with salt and pepper.
- Combine ingredients: In a large bowl, mix cooked rice, spinach mixture, shredded cheese, and lemon zest. Stir until well combined.
- Bake: Transfer mixture to a greased baking dish. Bake at 350°F (175°C) for 25-30 minutes, or until top is golden and bubbly.
- Cool and serve: Let the casserole rest for 5 minutes before serving to allow flavors to meld.

Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze in freezer-safe containers for up to 3 months. To reheat, thaw overnight in the fridge and warm in the oven at 350°F until heated through, or microwave with a splash of broth to prevent drying out.
Frequently Asked Questions
Can I use frozen spinach instead of fresh?
Yes! Use 10 oz frozen spinach, thawed and squeezed dry to remove excess water. This prevents a watery casserole.
What’s the best way to reheat a casserole without drying it out?
Add a splash of broth or milk before reheating. Cover with foil and warm slowly. Microwaving works too, but stir halfway through and cover with a damp paper towel.
Can I substitute the cheese with a dairy-free option?
Absolutely! Use vegan cheese alternatives like cashew-based or nutritional yeast for a dairy-free version. The spice blends work equally well with these substitutions.
How can I make this casserole gluten-free?
Ensure all broth and pre-made ingredients are certified gluten-free. Most traditional recipes don’t contain gluten, but check spice blends for cross-contamination.
What’s the ideal baking time and temperature for perfect results?
Bake at 350°F (175°C) for 25-30 minutes. The casserole is done when the top is golden brown and the internal temperature reaches 165°F (74°C). If using uncooked rice, it may need 45-55 minutes. Always check your specific recipe as times vary based on ingredients and dish size.

A spinach and rice casserole doesn’t have to be a side dish afterthought. With the right ingredients, spice combinations, and proper storage, it can become a standout meal.
