Easiest Broccoli Rice Casserole: A Comfort Food Classic

My grandmother, bless her heart, wasn’t exactly known for her adventurous cooking. But what she lacked in culinary innovation, she more than made up for in heart and simplicity. I remember summer potlucks at her house, the air thick with humidity and the scent of freshly cut grass. And there, amidst the potato salads and deviled eggs, would always be her broccoli rice casserole – a creamy, cheesy, comforting dish that somehow tasted like pure love. It wasn’t fancy, but it was a guaranteed crowd-pleaser, and to this day, just one bite takes me right back to her sun-drenched porch swing and the sound of her laughter.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour
• Servings: 4-6
• Dietary Type: Vegetarian

Ingredients

• 1 ½ cups cooked white rice (Minute Rice works great)
• 1 (16 ounce) package frozen broccoli pieces, thawed
• ½ red onion, chopped
• 1 (8 ounce) jar Cheese Whiz
• 1 (14 ounce) can cream of mushroom soup (Campbell’s)
• 1 (6 ounce) can sliced button mushrooms, drained
• ½ cup butter, sliced and softened (1 stick)
• 1 cup shredded cheddar cheese

Equipment Needed

• 2-quart casserole dish
• Mixing bowl
• Oven

Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Make sure your oven rack is positioned in the center.

2. In a large mixing bowl, combine the cooked white rice, thawed broccoli, chopped red onion, Cheese Whiz, cream of mushroom soup, and sliced button mushrooms.

3. Add the softened butter to the bowl. Use a spoon or spatula to gently stir all the ingredients together until they are well combined. Ensure the Cheese Whiz and cream of mushroom soup are evenly distributed throughout the mixture.

4. Pour the mixture into a 2-quart casserole dish. Spread it evenly to ensure consistent cooking.

5. Bake in the preheated oven for 35-40 minutes. The casserole should be bubbly and heated through.

6. Remove the casserole from the oven. Carefully stir the mixture. This helps to redistribute the heat and prevent the bottom from becoming overly browned.

7. Sprinkle the shredded cheddar cheese evenly over the top of the casserole.

8. Return the casserole to the oven and bake for an additional 10 minutes, or until the cheddar cheese is melted and bubbly, with a slightly golden-brown top.

9. Remove from the oven and let cool slightly before serving. This allows the casserole to set up a bit, making it easier to serve.

Expert Tips & Tricks

• Preventing a Soggy Casserole: Make sure to thoroughly drain the thawed broccoli. Excess moisture can lead to a soggy casserole. You can even squeeze out any extra water with a clean kitchen towel.
• Enhancing the Flavor: For a richer flavor, try browning the butter before adding it to the casserole. This adds a nutty depth that complements the other ingredients.
• Spice it Up: If you like a little heat, add a pinch of red pepper flakes or a dash of hot sauce to the mixture.
• Make-Ahead Tip: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add the shredded cheddar cheese just before baking to prevent it from drying out. You may need to add 5-10 minutes to the baking time if starting with a cold casserole.
• Adjusting for Different Ovens: Ovens can vary in temperature, so keep an eye on the casserole while it’s baking. If the top is browning too quickly, you can loosely tent it with aluminum foil.
• Creamier Texture: For an even creamier texture, consider adding a tablespoon or two of sour cream or cream cheese to the mixture.

Serving & Storage Suggestions

This broccoli rice casserole is delicious served warm as a side dish with roasted chicken, baked ham, or grilled fish. It also makes a hearty vegetarian main course.

To store leftovers, allow the casserole to cool completely before covering it tightly with plastic wrap or transferring it to an airtight container. It can be stored in the refrigerator for up to 3-4 days.

To reheat, you can microwave individual portions or reheat the entire casserole in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) until heated through. If reheating in the oven, cover the casserole with aluminum foil to prevent it from drying out.

Freezing is also an option. Wrap the cooled casserole tightly in plastic wrap and then in aluminum foil, or place it in a freezer-safe container. It can be stored in the freezer for up to 2 months. Thaw it overnight in the refrigerator before reheating.

FAQs (Frequently Asked Questions)

Q: Can I use fresh broccoli instead of frozen?

A: Yes, you can. You’ll need about 1 pound of fresh broccoli. Steam or blanch it until tender-crisp before adding it to the casserole.

Q: Can I use brown rice instead of white rice?

A: Absolutely! Brown rice will add a nuttier flavor and more fiber. You may need to adjust the cooking time slightly, as brown rice tends to absorb more liquid.

Q: Can I freeze this casserole?

A: Yes, you can freeze the unbaked or baked casserole. Make sure to wrap it tightly to prevent freezer burn. Thaw it completely before baking or reheating.

Q: The top of my casserole is browning too quickly. What should I do?

A: Loosely tent the casserole with aluminum foil to prevent the top from burning while the inside continues to cook.

Q: Can I make this casserole in a slow cooker?

A: Yes, you can. Combine all the ingredients in a slow cooker and cook on low for 4-6 hours, or on high for 2-3 hours. Stir occasionally. Add the shredded cheese during the last 30 minutes of cooking.
