• 2 cups cooked white rice (or brown rice for extra fiber)
• 2 cups fresh or frozen broccoli florets
• 1 small onion, finely chopped
• 2 tbsp unsalted butter
• 2 tbsp all-purpose flour
• 1 ½ cups milk (whole or 2%)
• ½ cup heavy cream (optional, for extra creaminess)
• 2 cups shredded sharp cheddar cheese (divided)
• ½ cup shredded mozzarella or Monterey Jack cheese
• ½ tsp garlic powder
• ½ tsp onion powder
• ½ tsp salt
• ¼ tsp black pepper
• ¼ tsp paprika (optional, for color)

Optional toppings:

• ½ cup crushed Ritz crackers or breadcrumbs
• 1 tbsp melted butter (to mix with topping)

Tools You’ll Need

• Medium saucepan or skillet
• 9×13-inch baking dish
• Whisk
• Mixing bowl
• Wooden spoon or spatula

Ingredient Additions & Substitutions

• Add protein: Stir in diced chicken, ham, or rotisserie turkey.
• Go green: Swap broccoli for spinach, kale, or mixed veggies.

How to Make Oven-Baked Cheesy Broccoli and Rice Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

Step 2: Steam the Broccoli

If using fresh broccoli, steam it for 3–4 minutes until just tender (bright green but not mushy). If using frozen, thaw and drain well to remove excess moisture.

Step 3: Make the Cheese Sauce

In a medium saucepan, melt butter over medium heat. Add chopped onion and cook until soft and translucent, about 3 minutes.

Stir in flour and cook for 1 minute, whisking constantly to form a roux. Gradually add milk (and cream, if using), whisking until smooth and thickened — about 3–4 minutes.

Remove from heat and stir in 1½ cups cheddar and ½ cup mozzarella until melted and creamy. Add garlic powder, onion powder, salt, pepper, and paprika.

Step 4: Combine Everything

In a large bowl, mix together cooked rice, broccoli, and the cheese sauce until everything is well coated.

Pour the mixture into your prepared baking dish, spreading evenly. Sprinkle the remaining ½ cup cheddar on top.

If you love a crunchy topping (and who doesn’t?), mix crushed crackers with melted butter and sprinkle over the cheese layer.

Step 5: Bake

Bake uncovered for 25–30 minutes, or until the casserole is bubbly and golden brown on top.

Step 6: Serve and Enjoy

Let it cool for 5–10 minutes before serving — this helps it set slightly for perfect scooping.

The smell of baked cheese and broccoli wafting from the oven? Absolutely heavenly.

What to Serve with Oven-Baked Cheesy Broccoli and Rice Casserole

This dish pairs beautifully with almost anything!

• As a side: Serve with baked chicken, roast beef, or grilled salmon.
• As a main: Add cooked sausage or shredded chicken right into the casserole.
• For holidays: It’s a must-have next to turkey and stuffing.
• With salad: A crisp green salad balances the richness perfectly.

Storage & Reheating

• Fridge: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze in a freezer-safe dish for up to 2 months. Thaw overnight before reheating.
• Reheat: Warm in a 350°F oven for 15–20 minutes or microwave in 1-minute intervals until hot.
