Broccoli Cheese Rice Casserole Recipe Cheez Whiz: Nostalgic Creamy Bake With Velvety Melt

There’s something deeply comforting about a creamy casserole that brings together tender rice, crisp-tender broccoli, and a velvety cheese sauce. This dish delivers nostalgia in every bite without complicated techniques.

I developed this recipe to recreate that childhood favorite using simple, accessible ingredients. The Cheez Whiz creates an ultra-smooth sauce that clings perfectly to each grain of rice and piece of broccoli.

The result is a creamy, satisfying bake with just the right texture contrast between the soft rice and slightly crisp broccoli. It’s the kind of side dish that disappears quickly from the table.

Perfect for family dinners or potluck gatherings, this casserole comes together with minimal effort and maximum flavor. The oven does most of the work for you.

Ingredients for Broccoli Cheese Rice Casserole Recipe Cheez Whiz

Pantry staples plus a few fresh picks create this nostalgic, creamy bake with perfect texture contrast.

The Cheez Whiz is non-negotiable here—grab the classic 15 oz jar (the shelf-stable kind). For the cheddar, block cheese shredded at home melts way better than pre-shredded. I snag mine from Costco for the best value. The rice should be long-grain white (jasmine or basmati work too). Broccoli can be fresh or frozen—just chop it small so it cooks evenly.

No Cheez Whiz? American cheese slices melted with milk gets close. Swap sharp cheddar for Pepper Jack if you want a kick. Out of whole milk? Half-and-half at the same amount works. The Dijon adds a subtle tang—regular yellow mustard in a pinch. Panko not on hand? Crushed saltines give a similar crunch.

Assemble it fresh, then bake immediately. Leftovers? Cover tight and refrigerate—good for 3-4 days. Reheat in microwave or oven (add a splash of milk to loosen the sauce). Freezes beautifully for up to 2 months.

Step-by-Step Instructions for Broccoli Cheese Rice Casserole

This method ensures a creamy, velvety texture with a perfectly crispy topping every time.

Step 1: Cook the Rice and Blanch the Broccoli

Rinse the 1.5 cups Long-Grain White Rice under cold water until the water runs clear. This removes excess starch and prevents a gummy texture. Cook the rice according to package directions, but reduce the water by ¼ cup so it’s slightly underdone—it’ll finish cooking in the oven.

While the rice cooks, bring a pot of salted water to a boil. Add the 3 cups Broccoli Florets and blanch for 2 minutes until bright green and just tender. Drain immediately and plunge into ice water to stop the cooking process. Drain again and pat dry. This keeps the broccoli vibrant and crisp-tender in the final bake.

Step 2: Sauté Aromatics and Make the Cheese Sauce

In a saucepan over medium heat, melt the 2 tbsp Unsalted Butter. Add the finely diced 0.5 whole Yellow Onion and cook for 3-4 minutes until translucent. Stir in the minced 2 cloves Garlic Cloves and cook for 30 seconds until fragrant.

Whisk in the 2 tbsp All-Purpose Flour to form a roux, and cook for 1 minute. Gradually whisk in the 1 cup Whole Milk until smooth. Stir in the 1 tsp Dijon Mustard, 0.5 tsp Kosher Salt, 0.25 tsp Ground Black Pepper, and 0.25 tsp Dried Thyme. Reduce heat to low and stir in the 15 oz Cheez Whiz and 1 cup Sharp Cheddar Cheese until fully melted and velvety smooth.

Step 3: Combine Everything and Transfer to Baking Dish

In a large bowl, combine the cooked rice, blanched broccoli, and cheese sauce. Stir gently but thoroughly to ensure every grain of rice and piece of broccoli is coated. The sauce should be thick enough to cling but still pourable—if it’s too thick, add a splash of milk to loosen it.

Transfer the mixture to a greased 9×13-inch baking dish and spread it into an even layer. Press down lightly to remove any air pockets, which helps the casserole set evenly during baking.

Step 4: Add Topping and Bake Until Bubbly

Sprinkle the 0.5 cup Panko Breadcrumbs evenly over the top of the casserole. For extra crispiness, I like to drizzle a little melted butter over the breadcrumbs or spray them lightly with cooking spray.

Bake at 375°F for 20-25 minutes until the casserole is bubbly around the edges and the breadcrumbs are golden brown. If the breadcrumbs start browning too quickly, tent the dish loosely with foil. Let it rest for 5 minutes before serving to allow the sauce to set slightly—this makes serving neater and ensures every bite is creamy and flavorful.

Storing and Reheating This broccoli cheese rice casserole recipe cheez whiz

Refrigerator Storage

Let your casserole cool for no more than 2 hours before transferring to an airtight container. I use glass Pyrex with snap-on lids from my local Boston market. It keeps beautifully in the fridge at 40°F or below for 3-4 days. 💡

Freezer Storage

This dish freezes wonderfully for up to 2 months without losing texture. I portion leftovers into quart-size freezer bags, leave 1 inch headspace for expansion, and squeeze out excess air. Label with the date—Biscuit my rescue dog helps me remember what’s inside!

For best results, freeze before baking if making ahead.

Oven Reheating

Preheat to 350°F and bake covered with foil for 20-25 minutes. Uncover and bake 5 more minutes to crisp the topping. Add a splash of milk if the sauce seems thick. This method restores that fresh-baked texture perfectly.

Microwave Reheating

For quick meals, microwave individual portions covered with a damp paper towel. Heat on 70% power for 2-3 minutes, stir, then continue in 1-minute intervals until reaching 165°F. The damp towel prevents drying. ❄️
