Step-by-Step Instructions
Step 1: Prepare Your Ingredients
Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking dish. Steam broccoli florets until bright green and just tender, about 3-4 minutes. Immediately transfer to cold water to stop the cooking process – this preserves the vibrant color and prevents mushiness in your final casserole.
Step 2: Create the Base
In a large skillet over medium heat, melt butter and sauté onions until translucent (about 4 minutes). Add garlic and diced bell pepper, cooking for another 2 minutes until fragrant. The aromatics at this stage will permeate your entire Homemade Cheesy Broccoli Rice Casserole (Better Than Grandma’s!) with deep flavor.
Step 3: Make the Cheese Sauce
Sprinkle flour over the vegetable mixture and stir constantly for 1 minute to cook out the raw flour taste. Gradually whisk in milk, ensuring no lumps form. Bring to a gentle simmer until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in 1½ cups of cheddar and ¼ cup Parmesan until fully melted. Add mustard powder, cayenne, salt, and pepper.
Step 4: Combine and Assemble
Gently fold the drained broccoli and cooked rice into the cheese sauce, ensuring even coating. Transfer the mixture to your prepared baking dish, spreading it evenly. Top with remaining cheese and crispy fried onions.
Step 5: Bake to Perfection
Bake uncovered for 25-30 minutes until bubbling around the edges and golden on top. Let stand for 5-10 minutes before serving – this resting period allows the flavors to meld and makes serving cleaner.
