Ingredients for cheddar's scratch kitchen broccoli cheese casserole
Golden crust, melty cheese, and tender broccoli—this casserole needs just 12 simple ingredients for restaurant-quality comfort.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Broccoli Florets 🥦 | 6 cups | Cut into bite-sized pieces |
| Sharp Cheddar Cheese 🧀 | 3 cups | Shredded, block preferred |
| Cream of Mushroom Soup 🍄 | 2 cups | Canned, condensed preferred |
| Milk 🥛 | 1 cup | Whole milk for creaminess |
| All-Purpose Flour 🌾 | ½ cup | For crispy topping |
| Unsalted Butter 🧈 | ½ cup | Melted for topping |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For subtle depth |
| Onion Powder 🧅 | ½ tsp | Enhances flavor |
| Baking Powder 🍞 | 1 tsp | For crispy topping |
| Green Onions 🧅 | 2 whole | Sliced for garnish |
The cheese is non-negotiable—sharp cheddar from a block makes all the difference (pre-shredded gets clumpy and lacks flavor). Kraft 2% or Cabot are my go-tos for that perfect balance of tang and creaminess. Broccoli should be bright green and firm—Trader Joe's or Costco usually have the freshest cuts. For the soup, cream of mushroom soup is essential (none of that powdered stuff)—Campbell's or French's work perfectly. The key to that signature crispy top? The flour-butter mixture—make sure your butter is fully melted before combining with flour for a smooth, even coating.
No sharp cheddar? Pepper jack or Monterey Jack add a nice kick, though you'll lose that classic cheddar flavor. Short on green onions? Fresh chives or extra black pepper work in a pinch. The baking powder is crucial—don't skip it if you want that puffed, golden crust. For a shortcut, you can use 1 cup of crushed Ritz crackers instead of the flour-butter topping, though it won't be quite as crispy. And if you're feeling fancy, add 1/2 cup of cooked bacon bits to the broccoli layer for extra indulgence (trust me, it's worth it).
This casserole reheats beautifully—best served at room temperature after baking, but it keeps well in the fridge for 4-5 days. For parties or holidays, double the recipe—it scales perfectly in a 9x13-inch baking dish. Leftovers freeze for up to 3 months (though honestly, it won't last that long). Store any extras in an airtight container, and if the top gets soggy when reheating, just broil for 2-3 minutes to restore that crispy magic.

Step-by-step instructions for cheddar's scratch kitchen broccoli cheese casserole
Here's how to create that irresistible golden crust with melty, pull-apart cheese—every time!
👨🍳 Step 1: Prepare the Broccoli and Cheese Mixture
Preheat your oven to 375°F while you prepare the filling. In a large bowl, combine the 6 cups fresh broccoli florets with the 2 cups cream of mushroom soup, 1 cup milk, 3 cups shredded sharp cheddar cheese, 1 teaspoon salt, ½ teaspoon ground black pepper, ½ teaspoon garlic powder, and ½ teaspoon onion powder. Stir everything together until the cheese is fully melted and the broccoli is evenly coated. The mixture should be thick but still pourable.
Here's the thing—don't skip stirring the cheese until fully melted. You want that smooth, creamy texture that makes this casserole so irresistible. If you see any unmelted cheese clumps, give it an extra minute with a rubber spatula to break them up completely. This is your flavor foundation, so take your time getting it right.
🍳 Step 2: Make the Crispy Topping
In a separate bowl, melt the ½ cup unsalted butter in the microwave for 30-45 seconds or until completely liquid. Then whisk in the ½ cup all-purpose flour, 1 teaspoon baking powder, and a pinch of salt. The mixture should thicken slightly and become crumbly. This is your golden crust secret!
I like to add the flour and baking powder all at once and mix vigorously with a fork. You're looking for a texture similar to coarse breadcrumbs but with a slightly sticky consistency. If it seems too dry, add just a teaspoon of milk to help bind it together. This topping is what creates that perfect crispy contrast with the creamy cheese filling underneath.
🥘 Step 3: Assemble and Bake the Casserole
Grease a 9x13-inch baking dish with butter or cooking spray. Pour the broccoli and cheese mixture evenly into the prepared dish, spreading it out into an even layer. Then sprinkle the crispy topping mixture evenly over the top, pressing down gently with your fingers to help it adhere. You want an even layer—about ¼-inch thick—so every bite gets that perfect crunch.
Bake for 30-35 minutes until the top is golden brown and the edges are bubbling. You'll know it's ready when you see that beautiful golden crust forming and the cheese underneath is melting into that perfect pull-apart texture. Don't be tempted to peek early—opening the oven too soon can cause the topping to lose its crispiness.
⏰ Step 4: Rest and Garnish
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting period allows the filling to set slightly and makes it easier to cut clean slices. While it's resting, slice the 2 whole green onions into thin rounds and sprinkle them evenly over the top for a fresh pop of color and flavor.
Here's where the magic happens: the contrast between the crispy golden topping and the creamy, cheesy broccoli filling is what makes this casserole so addictive. Serve warm with a side of crusty bread to soak up every last bit of that delicious cheese sauce. The flavors will be at their peak while still warm, so don't wait too long to dig in!
Pro Tips For Making Cheddar'S Scratch Kitchen Broccoli Cheese Casserole
- STEAM THE BROCCOLI FIRST: I learned this the hard way—raw broccoli florets in a casserole stay crunchy and watery. Give them a 3-minute steam in salted water before mixing with the soup sauce, then drain thoroughly. The texture becomes tender but still holds shape, and it soaks up the cheese sauce like a dream instead of turning mushy.
- GRATE YOUR OWN CHEESE: Store-bought shredded cheddar packs in anti-caking agents that make the sauce grainy. Skip the bagged stuff and grate sharp cheddar yourself—just don’t pulse it in a food processor (it releases too much fat). Pat the grated cheese with a paper towel to absorb excess moisture, or the sauce will split when baking.
- THICKEN THE SAUCE RIGHT: The cream of mushroom soup base is thin, and skimping on the flour roux is a fast track to a soggy top. Whisk in 2 tablespoons of flour with the milk before adding the soup, then simmer for 2–3 minutes until it thickens noticeably. This guarantees a creamy, clingy sauce that won’t turn to glue later.
- BAKE UNTIL THE EDGES CRISP: Covering the casserole with foil too long traps steam and keeps the cheese layer limp. After the first 20 minutes, uncover and bake until the edges turn golden and the top develops a slight crust—about 15–20 more minutes. The contrast between the crispy top and creamy center is what makes this dish sing.
Dietary considerations for cheddar's scratch kitchen broccoli cheese casserole
Gluten-Free Adaptation
For a gluten-free version, replace the all-purpose flour in the crispy topping with ½ cup gluten-free flour blend (like Bob's Red Mill 1:1) mixed with 1 teaspoon xanthan gum. Use the same amount of butter and baking powder, but add 1 tablespoon cornstarch to help bind the mixture.
The texture will be slightly different—more crumbly than crispy—but still delicious. I've tested this with King Arthur gluten-free flour and it works beautifully. 🌾
Dairy-Free Options
To make this casserole dairy-free, swap the cheddar cheese for 3 cups dairy-free shredded cheddar alternative (like Violife or Daiya) and use 1 cup unsweetened almond milk instead of regular milk.
For the crispy topping, melt ½ cup dairy-free butter (like Miyoko's) and mix with ½ cup gluten-free flour and 1 teaspoon baking powder. The flavor won't be identical, but it's a great option for those avoiding dairy. I recommend adding 1 teaspoon nutritional yeast to boost cheesy flavor.
Lower-Carb Version
Cut the carbs by replacing the broccoli with 6 cups cauliflower florets (raw or steamed) and using ½ cup almond flour instead of regular flour in the topping. Reduce the cream of mushroom soup to 1 cup and add ¼ cup heavy cream for richness.
The result is a lighter, lower-carb casserole that still delivers that satisfying cheesy pull-apart texture. I've found Trader Joe's almond flour works perfectly for this adaptation. 🥬
Vegetarian-Friendly
This recipe is already vegetarian, but you can enhance it by adding ½ cup cooked quinoa or ½ cup chickpeas to the broccoli layer for extra protein. For a meaty texture, try ½ cup crumbled tempeh or ½ cup vegan bacon bits.
The original recipe already includes all the essential vegetarian components, so no major changes are needed—just these optional add-ins for extra satisfaction. 🌱
Allergy-Friendly Swaps
For nut allergies, ensure your dairy-free cheese alternative is nut-free (check labels carefully). If you're avoiding mushrooms, use cream of celery soup instead of cream of mushroom soup—it provides a similar creamy base without the mushroom flavor.
For soy allergies, choose a dairy-free cheese made without soy lecithin (like Follow Your Heart Vegan Gourmet options). Always double-check ingredient labels when making substitutions. 🚫🧀

Frequently asked questions
Can I make this casserole ahead of time?
Assemble the casserole in a baking dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. When ready to bake, remove the foil and bake at 375°F for 35-40 minutes (5-10 minutes longer than fresh). This method actually enhances the flavors as the ingredients meld together overnight.
Why did my cheese casserole turn out greasy?
Greasy results usually happen when too much cheese is used or the broccoli isn't properly drained. Start with 3 cups of cheese and pat the broccoli dry before adding it to the mixture. Also, ensure your oven is fully preheated—cold spots can cause uneven cooking and excess oiliness. The crispy topping should be ¼-inch thick to absorb any excess moisture.
Can I use frozen broccoli instead of fresh?
Yes, but thaw and drain it thoroughly first! Use 6 cups of thawed, well-drained frozen broccoli and squeeze out any excess water with a clean kitchen towel. This prevents a watery casserole. For best texture, steam the frozen broccoli for 3-4 minutes before adding it to the cheese mixture to ensure it's fully heated and tender.
How do I make the crispy topping extra golden?
For a deeper golden color, broil the casserole for 1-2 minutes at the very end of baking (watch closely to avoid burning). Another trick is to mix 1 tablespoon cornstarch into the crispy topping mixture—it creates a lighter, crispier crust. Also, use butter-flavored baking spray on your baking dish instead of oil for extra browning.
What's the best way to reheat leftovers?
For best results, cover the casserole with foil and reheat at 350°F for 15-20 minutes until warmed through. If the top gets soggy, broil for 1-2 minutes at the end to restore crispiness. Microwave reheating works in a pinch, but it'll lose some of that perfect texture—cover with a damp paper towel and heat for 1-2 minutes on medium power.
