Why Make This Thanksgiving Dump And Bake Broccoli Casserole 3 Ingredient Easy
This recipe is a game-changer for anyone managing a crowded oven on Thanksgiving. First, the “dump and bake” method means you do not need to pre-cook the broccoli or make a complicated roux from scratch. You simply combine the ingredients directly in the baking dish. Second, it uses pantry staples that are easy to find and budget-friendly. Third, it is a crowd-pleaser that even picky eaters and kids enjoy. Finally, it frees up your stove burners for gravy and mashed potatoes, allowing you to focus on the turkey.
Ingredients
- 32 ounces (2 lbs) frozen broccoli florets, slightly thawed and drained
- 2 cans (10.5 ounces each) condensed cream of mushroom soup (undiluted)
- 2 cups shredded sharp cheddar cheese, divided
Directions
Step 1: Preparation
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with non-stick cooking spray or a thin layer of butter. Ensure your frozen broccoli is mostly thawed and that you have drained any excess water from the bag to prevent the casserole from becoming watery.
Step 2: Mixing and Baking
Dump the broccoli florets directly into the prepared baking dish. Spread the two cans of condensed cream of mushroom soup over the top. Add one cup of the shredded cheddar cheese. Use a large spoon to stir everything together until the broccoli is evenly coated with the soup and cheese. Smooth the mixture into an even layer. Place the dish in the oven and bake for 30 minutes.
Step 3: Finishing and Plating
Remove the dish from the oven and sprinkle the remaining one cup of cheddar cheese over the top. Return the casserole to the oven for an additional 5 minutes, or until the cheese is completely melted and bubbly. Let the casserole rest for 5 minutes before serving to allow the sauce to set. Serve warm alongside your turkey and stuffing.
Expert Tips for Perfect Thanksgiving Dump And Bake Broccoli Casserole 3 Ingredient Easy
For the best results, use “broccoli florets” rather than “cut broccoli” to avoid getting too many tough stems. If you have time, grate your own cheese from a block; pre-shredded cheese contains anti-clumping agents that can prevent it from melting smoothly. If the top isn’t as golden as you like, you can pop it under the broiler for 60 seconds at the very end. Always drain your broccoli well after thawing, as frozen vegetables release a lot of moisture during the baking process.
Delicious Variations
While this 3-ingredient version is spectacular on its own, you can easily customize it. For a crunchy topping, crush some Ritz crackers or fried onions and sprinkle them on top with the final layer of cheese. Swap the cream of mushroom soup for cream of chicken or cream of celery if you prefer a different flavor profile. If you want a little kick, use pepper jack cheese instead of cheddar. You can also turn this into a main dish by adding two cups of cooked, shredded chicken or ham to the mixture before baking.
Frequently Asked Questions
Can I use fresh broccoli instead of frozen?
Yes, you can use fresh broccoli. However, you should steam or blanch the fresh florets for about 3-4 minutes before adding them to the dish. Fresh broccoli takes longer to soften than frozen broccoli, so pre-cooking ensures it is tender by the time the cheese melts.

Can I make this casserole ahead of time?
Absolutely. You can assemble the broccoli, soup, and the first layer of cheese in the dish up to 24 hours in advance. Cover it tightly with foil and store it in the refrigerator. When you are ready to eat, bake it as directed, though you may need to add 5-10 minutes to the initial bake time since it is starting from a cold temperature.
Is there a way to make this lower in fat?
To reduce the fat content, use “98% fat-free” condensed cream of mushroom soup and a reduced-fat shredded cheddar cheese. You can also increase the ratio of broccoli to cheese to lower the overall calorie count per serving.
Can I freeze the leftovers?
Yes, this casserole freezes well. Store leftovers in an airtight container for up to 3 months. To reheat, thaw it in the refrigerator overnight and warm it in the oven at 350°F until heated through. Note that the texture of the broccoli may be slightly softer after freezing.
What if I don’t have cream of mushroom soup?
You can substitute any “cream of” soup you have on hand. Cream of chicken, cream of celery, or even cream of broccoli works perfectly. If you want a homemade substitute, you can use a thick white sauce (béchamel) mixed with sautéed mushrooms.

The Thanksgiving Dump and Bake Broccoli Casserole proves that you don’t need a long list of ingredients to create a memorable holiday meal.
