Ingredients
- 700 grams (3 cups) cooked rice (approximately 200 grams or 1 cup uncooked long-grain rice)
- 450 grams (16 ounces) frozen broccoli florets
- 1 small onion (approximately 100 grams), finely chopped
- 305 grams (10 3/4 ounces) can condensed cream of mushroom soup
- 120 ml (1/2 cup) milk
- 5 ml (1 teaspoon) salt
- 2.5 ml (1/2 teaspoon) freshly ground black pepper
- 1.25 ml (1/4 teaspoon) garlic powder
- 1.25 ml (1/4 teaspoon) paprika
- 240 grams (2 cups) shredded mild or medium cheddar cheese, divided
- Cooking spray or butter for greasing the baking dish
Instructions
- Preheat your oven to 175°C (350°F). Lightly grease a 23×33 cm (9×13-inch) baking dish with cooking spray or butter to prevent sticking and ensure easy cleanup.
- Prepare the broccoli. Thaw the frozen broccoli florets completely, then place them in a microwave-safe bowl and warm them in the microwave for approximately 5 minutes. This helps to further soften the florets and makes them easier to drain. After warming, drain the broccoli very, very well to remove excess moisture; soggy broccoli can make your casserole watery. If any florets are too large, cut them into smaller, bite-sized pieces for even distribution.
- In a large mixing bowl, combine the warm cooked rice, the finely chopped onion, condensed cream of mushroom soup, milk, salt, black pepper, garlic powder, and paprika. Stir these ingredients together thoroughly until they are uniformly mixed and the seasonings are well dispersed throughout the creamy base.
- Gently fold in 120 grams (1 cup) of the shredded cheddar cheese into the rice mixture. Then, add the prepared broccoli florets to the bowl. Carefully fold the broccoli into the mixture until it is evenly distributed. Be gentle to avoid mashing the broccoli.
- Spoon the entire broccoli-rice mixture into the prepared 23×33 cm (9×13-inch) baking dish, spreading it out evenly. Top the casserole generously with the remaining 120 grams (1 cup) of shredded cheddar cheese, ensuring a delicious cheesy crust.
- Bake the casserole in the preheated oven for 35 to 40 minutes. The casserole is ready when it is bubbly around the edges and the cheese on top is melted and just beginning to turn a beautiful golden brown. Serve hot and enjoy this comforting dish!

Tools You’ll Need
- 23×33 cm (9×13-inch) baking dish
- Large mixing bowl
- Microwave-safe bowl
- Measuring cups and spoons
- Spatula or large mixing spoon
Essential Success Tips
- First Tip: Ensure the broccoli is exceptionally well-drained after thawing and warming. Excess moisture can dilute the flavor and make the casserole watery.
- Second Tip: Use warm, freshly cooked rice if possible. It blends more easily with the other ingredients and helps the casserole heat more evenly in the oven.
- Third Tip: Do not overbake the casserole. Remove it from the oven once the cheese is bubbly and just starting to brown for the best creamy texture.
- Fourth Tip: For the best flavor and texture, use freshly shredded cheddar cheese rather than pre-shredded, as it melts more smoothly.
- Fifth Tip: Finely chop the onion. This ensures it cooks down properly and disperses its flavor evenly without crunchy raw bits.
Professional Cooking Secrets
- Chef's Secret One: Enhance the savory depth by adding a pinch of freshly grated nutmeg to the casserole mixture. It subtly brightens cream-based dishes without being overtly detectable.
- Chef's Secret Two: For an extra layer of texture, consider mixing 30 grams (1/4 cup) of panko breadcrumbs with 15 grams (1 tablespoon) of melted butter and sprinkling it over the top cheese layer before baking. It creates a delightful golden, crispy crust.
- Chef's Secret Three: Sauté the finely chopped onion in a tablespoon of butter until translucent before adding it to the mixture. This mellows its flavor and adds an additional layer of richness to the casserole's base.

Notes
- Ingredient Variation: Frozen chopped broccoli can be used instead of florets if preferred. The texture will be slightly different, but the flavor remains delicious.
- Make-Ahead Instructions: The casserole can be assembled up to 24 hours in advance. Prepare the broccoli mixture, spoon it into the casserole dish, top with the cheese, and refrigerate until ready to bake. When baking from chilled, increase the baking time to 60-75 minutes. If the cheese begins to brown too quickly, cover the dish loosely with foil partway through baking.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the microwave or oven until warmed through.
Frequently Asked Questions
Can I use fresh broccoli instead of frozen?
Yes, absolutely! If using fresh broccoli, cut it into small florets and blanch it in boiling salted water for 3-5 minutes until tender-crisp. Drain very well before adding it to the casserole mixture.
Is this casserole freezer-friendly?
This casserole freezes beautifully. You can freeze it unbaked (cover tightly with foil and plastic wrap) or baked. To bake from frozen, extend baking time significantly (up to 90 minutes) and keep it covered with foil for most of the baking time. Thaw overnight in the refrigerator for quicker reheating if desired.
What kind of rice works best?
Long-grain white rice, such as basmati or jasmine, works wonderfully as it stays fluffy and doesn't become overly sticky. You can also use brown rice for a nuttier flavor and added fiber, but ensure it's fully cooked before adding it to the mixture.
