Step‑by‑Step Instructions for Cheesy Broccoli Rice Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This crisp temperature will ensure that your Cheesy Broccoli Rice Casserole bakes evenly, resulting in a golden, bubbling masterpiece. While the oven warms up, gather your ingredients and prepare your mixing bowl for the next steps.
Step 2: Mix the Ingredients
In a large mixing bowl, combine 2 cups of cooked rice, 2 cups of broccoli florets, 1 cup of shredded cheddar cheese, 1 cup of cream of mushroom soup, and ½ cup of milk. Add ½ teaspoon each of garlic powder, onion powder, and ¼ teaspoon of black pepper. Mix everything until well blended, creating a creamy and vibrant mixture that embodies comfort on a plate.
Step 3: Prepare the Baking Dish
Next, lightly grease a 9x13 inch baking dish with non-stick spray or a drizzle of olive oil. Transfer the deliciously creamy mixture from the bowl into the dish, spreading it out evenly with a spatula. This even layering ensures that every bite of your Cheesy Broccoli Rice Casserole is filled with flavor and texture.
Step 4: Bake the Casserole
Place the baking dish into your preheated oven and bake uncovered for 25 minutes. You’ll notice the casserole bubbling delightfully around the edges, and the cheese beginning to melt beautifully. This initial baking allows all the ingredients to meld together into a savory comfort food dish.
Step 5: Add the Crispy Topping
After 25 minutes, carefully remove the casserole from the oven using oven mitts. It should look invitingly golden on top. Sprinkle 1 cup of crispy fried onions evenly across the surface. This topping adds a wonderful crunch, elevating the flavors of your Cheesy Broccoli Rice Casserole.
Step 6: Final Bake
Return the dish to the oven and bake for an additional 10 minutes. As it bakes, watch for the crispy fried onions to turn a lovely golden brown, adding the perfect texture to your hearty casserole. Once time is up, your kitchen will be filled with an irresistible aroma, signaling that your dish is ready to be enjoyed.
