Ingredients for campbell's broccoli cheese casserole
One can of soup, a handful of veggies, and a sprinkle of magic turn this into a cheesy, crunchy masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍲 | 2 cans | Condensed, not low-fat version |
| Broccoli Florets 🥦 | 3 cups | Fresh or frozen, chopped into bite-size pieces |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, real cheddar (not pre-shredded) |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| All-Purpose Flour 🌾 | ¼ cup | For thickening the sauce |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping (not regular breadcrumbs) |
| Butter 🧈 | ¼ cup | Melted, unsalted for flavor control |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For depth of flavor |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked black pepper |
| Optional Cooked Chicken Breast 🍗 | 1 cup | Diced, for protein boost |
| Optional Mozzarella Cheese 🧀 | ½ cup | Shredded, for extra melt |
The Campbell's Cream of Mushroom Soup is the flavor foundation—don't skimp on quality here. Grab the full-fat version from the store's canned soup aisle, and check the expiration date—older cans can taste flat. For the broccoli, fresh florets are ideal, but frozen works perfectly (no need to thaw). The sharp cheddar is non-negotiable—Kraft 2% or Cabot melts beautifully, while pre-shredded gets clumpy. If you're adding chicken, pre-cook and dice it before mixing—it'll stay tender while the casserole bakes. The Panko breadcrumbs are key for that crispy topping—Trader Joe's sells them in bulk for the best texture.
No Campbell's? Condensed mushroom soup from another brand works, but you'll lose that signature flavor. Short on broccoli? Cauliflower florets make a great substitute (use the same amount). Pre-shredded cheese? Drain and dry it first to avoid a watery casserole. The milk can be swapped for half-and-half if you want extra richness. For a vegan version, use plant-based cheese and coconut milk. The garlic and onion powders can be omitted if you're sensitive to those flavors, but they add serious depth. Want extra crunch? Add crushed Ritz crackers to the breadcrumb mix before topping.
This casserole tastes even better the next day—make it ahead and refrigerate for up to 3 days. For game day or parties, bake it in a disposable foil pan for easy serving. Leftovers reheat beautifully in the microwave (cover with a damp paper towel to keep it moist). The topping stays crispy for about 2 hours after baking, so serve it promptly. Store any extras in an airtight container with parchment paper between layers to maintain crispness. Freezes well for up to 2 months—just thaw in the fridge overnight before reheating.
Why You'll Love This Recipe
- One-Bowl Magic: I swear by this recipe when I’m too tired to wash extra dishes. Just mix the soup, milk, and flour in one bowl—no measuring cups, no fuss—then fold in the broccoli and cheese. The only tool you’ll need is a spatula, and honestly? That’s my kind of cooking.
- Cheesy Mushroom Umami Bomb: Between us, the cream of mushroom soup adds a depth that plain cheddar alone can’t match. That earthy, savory note from the mushrooms makes the sharp cheddar sing—like a cozy hug for your taste buds, but way more delicious. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: This casserole actually improves the next day. The broccoli softens just enough to soak up all that creamy goodness, and the cheese gets that perfect melty pull. I make a double batch on Sundays because reheating it is basically free lunch for the week.
- Budget-Friendly Crowd-Pleaser: Sharp chedddar and frozen broccoli florets keep this recipe affordable, but it still feels special. I’ve served it at potlucks, game nights, and even as a side for my book club—no one ever questions the ingredients, just the seconds they’re asking for. (My secret weapon.)
Step-by-step instructions for Campbell's broccoli cheese casserole
This cheesy, crisp-topped masterpiece delivers comfort food perfection with minimal effort. Let's build it layer by layer.
Prepare the Cheesy Sauce Mixture
In a large mixing bowl, combine the 2 cans Campbell's Cream of Mushroom Soup with the 0.5 cup milk, stirring until completely smooth. The soup should be fully incorporated with no visible clumps. Add the 2 cups sharp cheddar cheese and stir until melted and evenly distributed throughout the mixture.
In a separate small bowl, whisk together the 0.25 cup all-purpose flour, 1 tsp garlic powder, 1 tsp onion powder, 0.5 tsp salt, and 0.25 tsp black pepper. This dry blend will thicken the sauce and add depth of flavor. Gradually sprinkle this mixture into the soup while stirring constantly to prevent lumps from forming. The sauce should thicken slightly as you incorporate the flour blend.
Assemble the Casserole Layers
Preheat your oven to 375°F. In a 9x13-inch baking dish, spread the prepared sauce mixture evenly across the bottom, creating a thin base layer. This will ensure even cooking and prevent the broccoli from sitting in excess moisture.
Next, distribute the 3 cups broccoli florets evenly over the sauce layer, making sure each piece is submerged in the cheesy mixture. If using the 1 cup optional cooked chicken breast, sprinkle it evenly over the broccoli. Finally, add the 0.5 cup optional mozzarella cheese on top if desired - this will create a beautiful melt during baking.
Create the Crispy Topping Layer
In a small bowl, combine the 0.5 cup panko breadcrumbs with the 0.25 cup melted butter. The mixture should look like wet sand with visible butter flecks. Sprinkle this evenly over the entire casserole, pressing down gently with the back of a spoon to ensure good contact with the cheese layer below.
Here's where the magic happens: the panko will create that perfect crispy, golden-brown crust we all love. For extra flavor, you could add a pinch of paprika or cayenne to the breadcrumb mixture, but keep it simple with just the butter for classic flavor.
Bake to Golden Perfection
Place the baking dish on the middle rack of your preheated oven and bake for 25-30 minutes. You'll know it's ready when the top is golden brown and bubbly, and the edges are beginning to crisp. The casserole should smell intensely cheesy and slightly nutty from the panko.
For best results, avoid opening the oven door during baking. The heat loss will cause the top to steam rather than crisp. If you're unsure whether it's done, insert a knife into the center - it should come out clean with just a few moist crumbs clinging to it.
Rest and Serve with Confidence
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice and serve without losing the crispy topping. The internal temperature should reach 165°F at the center.
Cut into squares and serve immediately with a side of crusty bread or a simple green salad. The contrast of the crispy top against the creamy cheese and tender broccoli makes each bite irresistible. This casserole reheats beautifully, so it's perfect for meal prep or leftovers.
Pro Tips For Making Campbell'S Broccoli Cheese Casserole
- STEAM THE BROCCOLI FIRST: I learned this the hard way—raw broccoli in your casserole means a mushy, waterlogged mess. Steam the florets for 3-4 minutes until just tender-crisp, then drain and pat very dry. That extra step keeps the texture perfect and prevents a soggy top crust.
- WHISK THE SOUP THIN: The Campbell’s Cream of Mushroom soup is thick, and that’s fine—but resist the urge to dump it straight into your baking dish. Whisk it with the milk before adding flour to make a smoother roux. This prevents lumps and gives you a creamier, more consistent sauce.
- DON’T OVERMIX THE CHEESE: Sharp cheddar melts differently than mild, and if you blend it into the soup too aggressively, you’ll end up with a grainy, clumpy casserole. Cut the cheese into small cubes, sprinkle them on top of the soup mixture, then gently fold just until combined. The last few inches of stirring should be light—think "marble swirls," not "smooth batter."
- BAKE UNTIL THE EDGES BROWN: Your casserole is done when the cheese is fully melted and the edges are golden, not when the center looks set. I used to pull it out too soon because the top looked "done," only to find a gooey, unmelted middle. Bake 10-15 minutes past the recipe’s suggested time, checking the edges for color.
Make-ahead tips for this campbell's broccoli cheese casserole
Prep Ahead Strategy
Assemble the entire casserole—sauce, broccoli, and topping—up to 24 hours before baking. Store it uncovered in the refrigerator to prevent sogginess. When ready to bake, simply pop it in the oven at 375°F for 30-35 minutes (the extra 5 minutes account for the cold start).
This is my go-to for game day prep—just cover and refrigerate until serving time. 📅
Freezer-Friendly Assembly
For long-term meal prep, assemble the casserole in a foil-lined baking dish and freeze it uncovered for 2 hours before transferring to an airtight container. When ready to bake, thaw overnight in the fridge, then bake as directed.
The texture stays perfect—just add 5-10 extra minutes to the baking time if it feels cold when starting. Label containers with the date to track freshness. ❄️
Portion Control Tips
Divide the assembled casserole into individual 8x8-inch baking dishes for single-serving portions. Bake at 375°F for 25 minutes—perfect for lunches or reheating. Store extras in glass Pyrex containers with parchment paper between layers to maintain crispness.
I use this method for work lunches—just reheat covered in the microwave for 2 minutes. 💡
Double Batch Hack
Make two casseroles at once by doubling the recipe in a 9x13-inch pan and a 8x8-inch pan. Bake them simultaneously for 30 minutes—the smaller pan finishes first.
This is ideal for feeding crowds or freezing half for later. Use the smaller pan for quick reheats while the larger pan stays fresh in the fridge. 🍽️
Game Day Serving
Prepare the casserole in a foil pan for easy transport—just slide it onto a baking sheet before baking. Keep it warm in a 200°F oven while serving, or cover with foil and let it sit at room temperature for 30 minutes before serving.
Add a side of carrot sticks or pickles to balance the richness. 🏈
Reheating Leftovers
Microwave individual portions covered with a damp paper towel for 1-2 minutes on high, stirring halfway. For stovetop reheating, cover with foil and warm over low heat for 10 minutes. Avoid overcooking—the topping loses crispness quickly. I always reheat leftovers in 1-minute bursts to check doneness. 🔥

Frequently asked questions
Can I use a different Campbell's soup flavor for this casserole?
While the recipe calls for Cream of Mushroom, you can absolutely use Cream of Celery or even Cream of Chicken Soup for a different flavor profile. Just adjust seasonings—add more garlic powder for celery soup or a pinch of paprika for chicken soup. The texture will be slightly different but still delicious!
Why does my casserole come out watery instead of creamy?
Watery results usually happen when using pre-shredded cheese (it contains anti-caking agents that release moisture) or not draining frozen broccoli properly. Always drain and dry frozen veggies thoroughly, and use fresh shredded cheese. If needed, add 1-2 tablespoons of flour to thicken the sauce before baking.
How can I make this casserole kid-friendly?
Cut the broccoli into smaller florets and stir them into the sauce before baking so they're more evenly distributed. For picky eaters, add diced ham or extra cheese to the sauce mixture. Serve with buttered noodles on the side to make it feel like a complete meal. The crispy topping usually wins over even the most veggie-averse kids!
What's the best way to reheat leftovers without losing the crispy topping?
Reheat covered portions in the microwave for 1 minute, then uncover and microwave 30 seconds more to revive the crisp. For oven reheating, cover with foil and bake at 350°F for 15 minutes, then uncover for the last 2 minutes to crisp the top again. Never microwave uncovered—it'll make everything soggy!
Can I make this casserole in a smaller baking dish?
Yes! For an 8x8-inch dish, reduce baking time to 20-25 minutes and cover with foil for the first 15 minutes to prevent over-browning. The smaller surface area means faster cooking. For a 9-inch pie dish, bake for 30 minutes but check for doneness at 25 minutes—smaller pans cook quicker!
