How to Make Broccoli Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F. Get a large pot of water boiling on the stove for blanching the broccoli.
Step 2: Sauté the Onion
In a medium saucepan, add the diced onion and butter. Cook over medium-low heat until the onion is softened and translucent, which should take about 5 minutes.
Step 3: Make the Cheese Sauce
Stir in the flour, garlic powder, and black pepper. Cook this mixture for another 2 minutes, then gradually pour in the milk, whisking constantly to avoid lumps.
Step 4: Thicken the Sauce
Continue to whisk the mixture over medium heat until it becomes thick and bubbly. Remove the saucepan from the heat and stir in the dry mustard, paprika, cream cheese, and 1 ½ cups of shredded cheddar cheese until melted.
Step 5: Season the Mixture
Taste the cheese sauce and adjust the seasoning with more salt and pepper if needed. It should have a balanced flavor that enhances the casserole.
Step 6: Blanch the Broccoli
Add the broccoli to the boiling water for 1-2 minutes until it turns bright green but remains crisp. Drain it well to remove excess water and prevent a soggy casserole.
Step 7: Combine Ingredients
In a large bowl, stir together the cooked rice, blanched broccoli, and cheese sauce. Ensure everything is coated well, then transfer the mixture to a greased 2-quart casserole dish.
Step 8: Bake the Casserole
Top the casserole with the remaining cheddar cheese. Bake in the preheated oven for 35 minutes or until the cheese is bubbly and lightly browned.

Pro Tips from My Kitchen
✓ Fresh Broccoli – For the best flavor and texture, use fresh broccoli instead of frozen. It will retain its crispness and bright color.
✓ Cheese Options – Feel free to mix different cheeses like mozzarella or gouda for varied flavors. Just ensure to keep a strong cheese for the topping.
✓ Cooking Rice – Use slightly undercooked rice as it will absorb some sauce during baking, preventing a mushy texture in the casserole.
✓ Adjusting Thickness – If the cheese sauce is too thick, add a little more milk while whisking to get the desired consistency before combining with the other ingredients.
✓ Serving Suggestions – Pair this casserole with a side salad or some crusty bread for a complete meal. It’s also delicious alongside grilled chicken or fish.
