Cheesy Broccoli Rice Casserole is a staple in my kitchen because it’s the kind of comfort food I can always count on. It comes together with simple ingredients, and the creamy, cheesy texture makes it a hit with everyone at the table. I love how the aroma of melted cheese and sautéed onions fills the kitchen as it bakes.

This casserole is my go-to for busy weeknights or when I need a reliable side for a potluck. It’s hearty enough to stand alone for lunch, but I often serve it alongside roast chicken or grilled sausages. The tender broccoli and fluffy rice, coated in a rich cheese sauce, make every bite satisfying.

What makes this dish special to me is its versatility. I can use leftover rice or swap in whatever cheese I have on hand. It’s also a great way to get picky eaters to enjoy broccoli, thanks to the creamy, savory flavors.

When it comes out of the oven, the golden, bubbly top is hard to resist. It’s practical, filling, and always disappears fast at my table.

Ingredients

This recipe uses ingredients you’re likely to have on hand, making it a practical choice for busy nights. Fresh or frozen broccoli both work well, and you can use any cooked rice. The cheese sauce is simple but delivers plenty of rich flavor.

• 2 cups cooked white or brown rice
• 3 cups broccoli florets (fresh or frozen, chopped)
• 1 medium yellow onion, finely diced
• 2 cloves garlic, minced
• 2 tablespoons unsalted butter
• 1 can (10.5 oz) condensed cream of mushroom soup
• 1/2 cup whole milk
• 2 cups shredded sharp cheddar cheese, divided
• 1/4 cup grated Parmesan cheese
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/2 teaspoon paprika (optional, for topping)
• Cooking spray or extra butter for greasing

Step-by-Step Instructions

The casserole comes together quickly. You’ll start by sautéing the aromatics, then mix everything together and bake until golden and bubbly. Make sure to pre-cook the rice and chop the broccoli for even cooking.

1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
2. If using fresh broccoli, steam or microwave florets until just tender (about 3–4 minutes). Drain well.
3. In a large skillet, melt butter over medium heat. Add diced onion and cook until soft, about 4 minutes. Stir in garlic and cook 1 minute more.
4. In a large bowl, combine cooked rice, broccoli, sautéed onion and garlic, condensed soup, milk, 1 1/2 cups cheddar, Parmesan, salt, and pepper. Mix well.
5. Spread the mixture evenly in the prepared baking dish.
6. Sprinkle remaining 1/2 cup cheddar cheese evenly over the top. Dust with paprika if using.
7. Bake uncovered for 30–35 minutes, until the casserole is hot and the top is golden and bubbling.
8. Let rest 5–10 minutes before serving to set.
