Ham Broccoli Rice Casserole Recipe: Cheesy One-Dish Family Dinner

This casserole solves weeknight dinner with minimal effort and maximum comfort. I developed it during busy weeks when my kitchen felt more like a construction zone than a cooking space.

The one-dish method combines tender ham, crisp broccoli, and fluffy rice under a blanket of melted cheese. No complicated techniques—just layer and bake until bubbly and golden.

What emerges is a family-friendly meal that’s creamy, savory, and satisfying. The broccoli stays slightly crisp, while the rice soaks up the cheesy sauce for perfect texture.

Ideal for using leftover ham or a quick, hearty dinner. Here’s how to make it.

Ingredients for Ham Broccoli Rice Casserole

Nothing exotic here—just good stuff for a comforting, cheesy one-dish dinner.

The ham is the flavor base here. Leftover holiday ham works perfectly (that’s how I developed this), but any deli ham from Whole Foods or your local grocery store will do. Look for low-sodium if you’re watching salt. The broccoli can be fresh or frozen—frozen from Trader Joe’s saves time and actually holds up better in the oven.

No cooked ham? Diced turkey or rotisserie chicken are great swaps. Fresh out of broccoli? Cauliflower or green beans work well (just chop to similar size). The rice can be swapped for quinoa if you want extra protein. For the cheese, Colby Jack or Monterey Jack melt beautifully too—just avoid pre-shredded (it doesn’t melt as smoothly).

Leftovers keep in the fridge for 4-5 days and reheat like a dream. I’ve frozen portions for up to 3 months—thaw overnight before reheating. The broccoli might soften a bit, but the flavor stays just as good.

Step-by-Step Instructions for Ham Broccoli Rice Casserole

Here’s how I make this comforting casserole with minimal effort and maximum flavor.

Step 1: Cook the Rice and Prep the Vegetables

Start by cooking the 1.5 cups uncooked white rice according to package directions, but use chicken broth instead of water for extra flavor. While the rice cooks, chop the yellow onion finely and mince the 2 cloves garlic cloves.

If using fresh 3 cups broccoli florets, cut them into bite-sized pieces. For frozen, thaw and drain well to prevent excess moisture. I like to steam the broccoli for 3-4 minutes until bright green and slightly tender—this prevents it from becoming mushy during baking.

Dice the 2 cups cooked ham into small cubes if it isn’t already. Having all your ingredients prepped before assembling makes the process smooth and stress-free.

Step 2: Make the Creamy Cheese Sauce

In a saucepan, melt the 2 tbsp unsalted butter over medium heat. Add the diced yellow onion and cook for 3-4 minutes until soft and translucent. Stir in the minced garlic cloves and cook for 30 seconds until fragrant.

Sprinkle in the 0.25 cup all-purpose flour and whisk constantly for 1 minute to cook off the raw flour taste. Slowly pour in the 1 cup whole milk and 2 cups chicken broth, whisking continuously to prevent lumps.

Add the 1 tbsp Dijon mustard, 0.5 tsp salt, and 0.25 tsp black pepper. Cook for 3-5 minutes until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in 1.5 cups of the shredded cheddar cheese until melted and smooth.

Step 3: Combine All Ingredients

In a large bowl, combine the cooked rice, steamed broccoli florets, diced cooked ham, and the cheese sauce. Stir everything together until evenly coated. The mixture should look creamy with visible chunks of ham and broccoli.

I always taste at this point and adjust seasoning if needed. The sauce should be rich and flavorful, with a subtle tang from the mustard. If it seems too thick, you can thin it slightly with a splash of milk.

Step 4: Bake Until Bubbly and Golden

Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the remaining 0.5 cup shredded cheddar cheese evenly over the top. This creates that beautiful, golden-brown cheesy crust everyone loves.

Bake at 375°F for 20-25 minutes until the casserole is bubbling at the edges and the top is lightly browned. If the top starts browning too quickly, tent loosely with foil.

Let it rest for 5 minutes after removing from the oven. This allows the casserole to set slightly, making it easier to serve neat portions.

Creative Variations of ham broccoli rice casserole

Turkey Swap Variation

Trade the ham for 2 cups diced cooked turkey—perfect for using up Thanksgiving leftovers. The milder flavor lets the cheddar shine. I tested this with rotisserie chicken from Whole Foods and it worked beautifully too. 💡

Vegetarian Version

Skip the meat entirely and add 1 can drained chickpeas or 2 cups sautéed mushrooms for protein. The broccoli and rice combo still delivers that comforting texture. Use vegetable broth instead of chicken for a fully plant-based meal.

Spicy Kick

Add ½ tsp cayenne pepper to the cheese sauce or top with pickled jalapeños before baking. The heat cuts through the richness nicely. I discovered this trick when my brother dared me to “spice it up” one Christmas.

Lighter Option

Use cauliflower rice instead of white rice and 2% milk to reduce carbs. The texture changes slightly, but it’s still delicious. I make this version when I’m craving comfort food without the guilt.

Extra Cheesy Upgrade

Mix in 1 cup shredded Monterey Jack with the cheddar for a gooier texture. Or try Pepper Jack for a subtle spicy note. The extra meltiness makes it kid-approved every time.

Breakfast Twist

Add 4 beaten eggs to the mixture before baking for a frittata-like casserole. Perfect for brunch—just bake at 350°F for 30 minutes until eggs are set. My Nonna would’ve loved this one. 🥗
