Ingredients For Broccoli Cheese Casserole Recipe
Broccoli florets: Fresh or frozen, these are the main vegetable component of the dish.
Cheddar cheese: Shredded, this adds a rich, cheesy flavor to the casserole.
Cream of mushroom soup: A condensed soup that provides a creamy base with a hint of mushroom flavor.
Sour cream: Adds creaminess and a slight tang to the mixture.
Ritz crackers: Crushed, these create a crunchy topping for the casserole.
Butter: Melted, it helps bind the ritz crackers together for the topping.
Technique Tip for This Recipe
When preparing the broccoli for this casserole, consider blanching the fresh florets in boiling water for 2-3 minutes before combining them with the other ingredients. This technique helps to maintain the vibrant green color and ensures the broccoli is tender but not mushy. If using frozen broccoli, make sure to thaw and drain it thoroughly to avoid excess moisture in the casserole.

How to Store or Freeze This Casserole
Allow the broccoli cheese casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container. Store it in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave or the entire dish in the oven at 350°F (175°C) until warmed through.
For longer storage, consider freezing the casserole. First, wrap the entire baking dish tightly with plastic wrap, then cover with aluminum foil. Alternatively, you can portion the casserole into individual servings and store them in freezer-safe containers.
Label the container with the date and contents to keep track of its freshness. The broccoli cheese casserole can be frozen for up to 2-3 months.
When ready to enjoy, thaw the casserole in the refrigerator overnight. Reheat in the oven at 350°F (175°C) until the casserole is bubbly and heated through, which usually takes about 20-30 minutes. If reheating from frozen, it may take a bit longer, so keep an eye on it.
To maintain the crunchy topping, consider adding a fresh layer of crushed ritz crackers mixed with melted butter before reheating. This will ensure the casserole retains its delightful texture.
How to Reheat Leftovers
Oven Method:
- Preheat your oven to 350°F (175°C).
- Place the leftover broccoli cheese casserole in an oven-safe dish.
- Cover the dish with aluminum foil to prevent the cheese from drying out.

- Remove the foil for the last 5 minutes to crisp up the ritz cracker topping.
Microwave Method:
- Transfer a portion of the casserole to a microwave-safe dish.
- Cover the dish with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape.
- Microwave on medium power for 2-3 minutes.
- Stir the casserole halfway through to ensure even heating.
- Continue microwaving in 1-minute increments until the broccoli and cheese are hot.
Stovetop Method:
- Place the leftover broccoli cheese casserole in a non-stick skillet.
- Add a splash of milk or cream to help maintain moisture.
- Heat over medium-low, stirring occasionally to prevent sticking.
- Cook until the casserole is heated through, about 10-15 minutes.
Air Fryer Method:
- Preheat your air fryer to 350°F (175°C).
- Place the casserole in an air fryer-safe dish or line the basket with aluminum foil.
- Heat for 10-12 minutes, checking halfway through to ensure even heating.
