Copycat Cheddars Broccoli Rice Casserole Recipe: Cheesy Bake with Crispy Topping

This dish recreates the beloved restaurant favorite with a crispy golden topping and creamy cheese center. The combination of tender rice, fresh broccoli, and sharp cheddar delivers comfort in every bite.

I developed this version after perfecting the balance between cheesy richness and textural contrast. The baked topping achieves that signature crunch while keeping the interior velvety smooth.

The casserole comes together in one baking dish, making it as practical as it is delicious. It’s the ideal make-ahead side that reheats beautifully.

Serve it alongside roasted chicken or as a satisfying vegetarian main. This recipe brings restaurant quality to your home kitchen.

Ingredients for Copycat Cheddars Broccoli Rice Casserole

Pantry staples and fresh veggies bring this restaurant classic to life at home.

The cheddar is non-negotiable—sharp cheddar from a block melts perfectly (pre-shredded has anti-caking agents that make it grainy). Cheddars restaurant likely uses a blend, but sharp cheddar alone nails the flavor. For the rice, long-grain white gives that classic texture. I grab mine from Costco in bulk. The broccoli should be fresh, not frozen, for the best bite.

Swap sharp cheddar for Colby Jack if you want milder flavor. No fresh broccoli? Frozen florets work (thaw and drain well first). Out of cornflakes? Crushed Ritz crackers or panko give similar crunch. Whole milk sub: half-and-half for extra richness or 2% milk in a pinch. The dry mustard is subtle but important—Dijon works too.

Assemble up to 24 hours ahead—just add the topping before baking. Leftovers keep 4-5 days refrigerated. Freezes beautifully for 3 months (thaw overnight before reheating). The topping stays crisp if you broil 2 minutes before serving.

Step-by-Step Instructions for Cheddar’s Broccoli Rice Casserole

Here’s how I recreate that signature cheesy bake with its irresistible crispy topping at home.

Step 1: Cook Rice and Prep Vegetables

First, cook the 2 cups Long-Grain White Rice according to package instructions until tender. While it cooks, cut the 3 cups Fresh Broccoli into small, uniform florets and finely dice the 0.5 whole Yellow Onion. I like to blanch the broccoli in boiling water for 2 minutes to soften it slightly—this prevents a crunchy texture in the final dish.

Drain the rice well and spread it on a baking sheet to cool slightly. This prevents the rice from turning mushy when mixed with the other ingredients. The rice should be just warm to the touch when you’re ready to assemble the casserole.

Step 2: Make the Creamy Cheese Sauce

In a saucepan over medium heat, melt the 0.5 cup Unsalted Butter. Whisk in the 0.25 cup All-Purpose Flour and cook for 1-2 minutes until bubbly and light golden. This roux is the foundation of your sauce—don’t let it brown or it’ll taste bitter.

Gradually whisk in the 1.5 cups Whole Milk, then add the minced 2 cloves Garlic Cloves, 1 tsp Salt, 0.5 tsp Ground Black Pepper, and 0.5 tsp Dry Mustard. Cook, stirring constantly, until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in 1.5 cups of the 2 cups Sharp Cheddar Cheese until melted and smooth.

Step 3: Combine All Ingredients

In a large bowl, combine the cooked rice, blanched broccoli, diced onion, and cheese sauce. Stir gently but thoroughly to distribute everything evenly. In a separate bowl, beat the 2 whole Large Eggs and fold them into the rice mixture. The eggs act as a binder, giving the casserole its signature custardy texture.

Transfer everything to a greased 9×13-inch baking dish. Sprinkle the remaining 0.5 cup Sharp Cheddar Cheese evenly over the top. At this point, the mixture should look creamy with visible flecks of broccoli and onion throughout.

Step 4: Add Topping and Bake

In a small bowl, mix the 1 cup Crushed Cornflakes with the 0.25 cup Melted Butter until the cereal is evenly coated. Sprinkle this mixture evenly over the casserole, pressing down lightly so it adheres to the cheese below. This topping is what gives the dish its signature crunch.

Bake at 350°F for 30-35 minutes until the casserole is bubbly around the edges and the topping is deep golden brown. Let it rest for 5 minutes before serving—the sauce will thicken slightly as it cools, making it easier to slice into perfect squares.

Serving Suggestions for Leftovers

Family-Style Presentation

Serve this straight from the baking dish for a cozy, communal feel. The golden cornflake topping looks stunning when piped with a quick drizzle of melted butter right before serving. I always use my Le Creuset stoneware for that rustic presentation. 💛

Garnish with Freshness

A sprinkle of chopped parsley or green onions adds a pop of color against the creamy cheese. For extra richness, I sometimes add crumbled bacon bits on top—the salty crunch pairs perfectly with the cheesy base.

Protein Pairings

This casserole shines alongside roasted chicken or grilled pork chops. The mild flavor complements without competing, making it ideal for weeknight dinners. I love serving it with honey-glazed ham for Sunday suppers.

Vegetarian Main Option

For a meat-free meal, add black beans or sautéed mushrooms to the mix before baking. The extra protein makes it hearty enough to stand alone. My vegetarian friends rave about this version.

Side Salad Combo

A crisp garden salad with a tangy vinaigrette cuts through the richness beautifully. I toss mixed greens with cherry tomatoes and a balsamic dressing for contrast. The acidity balances the creamy casserole perfectly.

Bread Basket Addition

Warm dinner rolls or garlic bread are perfect for soaking up any extra cheesy sauce. I bake my rolls in the same oven while the casserole rests. It’s the ultimate comfort meal setup.
