Ingredients for cheddars restaurant broccoli cheese casserole copycat
Sharp cheddar, creamy sauce, and crispy topping—here's how to recreate Cheddar's iconic casserole at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Sharp Cheddar Cheese 🧀 | 2 cups | Freshly grated, sharp variety |
| Broccoli Crowns 🥦 | 2 ½ lbs | Fresh, florets cut from stems |
| Heavy Cream 🥛 | 1 cup | Full-fat for creaminess |
| Milk 🥛 | 1 cup | Whole milk preferred |
| All-Purpose Flour 🌾 | ¼ cup | For roux base |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for roux |
| Yellow Onion 🧅 | 1 whole | Medium size, finely diced |
| Garlic Cloves 🧄 | 4 cloves | Minced for flavor |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping |
| Optional Bacon 🥓 | 4 oz | Cooked, crumbled |
| Optional Ham 🥓 | ½ cup | Diced for extra flavor |
| American Cheese Slices 🧀 | 1 cup | Shredded for topping |
The cheddar is non-negotiable—sharp, freshly grated from a block delivers that signature tang. Kraft 2% Milk Sharp or White Cheddar work best. Skip pre-shredded; it gets clumpy and lacks flavor. Broccoli should be bright green and firm, not wilted. Trader Joe's or Whole Foods carry good quality florets. For the roux, cold butter is key—don't let it brown before adding flour, or you'll taste it. The onion? Yellow, medium-sized—red adds color but changes flavor slightly.
No sharp cheddar? Monterey Jack or Colby Jack blends work in a pinch, but expect milder flavor. Heavy cream substitute? Half-and-half with 2 tbsp sour cream keeps it creamy. The optional bacon or ham? Cook it first and drain well—no one wants soggy toppings. For the crispy crust, Panko plus a sprinkle of paprika adds color and crunch. Pre-shredded American cheese? Use the good stuff from a block—it melts better than the canned kind.
Assemble this casserole up to 24 hours ahead—it tastes even better the next day. Cover and refrigerate, then bake straight from the fridge for 10-15 minutes longer to melt the cheese evenly. Leftovers keep 4-5 days in the fridge, but honestly? It disappears faster than that. For freezing, bake first, then portion into single-serving containers—reheat covered at 350°F for 20 minutes until bubbly.
Why You'll Love This Recipe
- One-Pot Magic: That thick, creamy sauce? It all comes together in one bowl—no fancy techniques, just a whisk and a sheet pan. Honestly, the only "chop" I do is snapping those broccoli crowns (which take seconds), and then it’s hands-off until the timer dings.
- Melty Perfection: Sharp cheddar baked until bubbly and golden? That’s the moment this dish steals the show. The flour-thickened sauce clings to every floret, while the top gets that crispy, buttery crust—like a hug from your favorite comfort food.
- Leftovers for Days: Between us, I make this on Sunday and eat it Wednesday night. The sauce stays rich, the cheese doesn’t get rubbery, and reheating? Just 90 seconds in the microwave. My kids’ school lunches have never been more popular.
- Budget Crowd-Pleaser: A block of sharp cheddar and a few florets stretch to feed four (or five if you’re me). Heavy cream and milk add luxury without breaking the bank—this is the kind of dish that makes grocery night feel like a win. Plus, no one ever complains.
Step-by-step instructions for cheddars restaurant broccoli cheese casserole
Here's the exact method for that legendary crispy-topped, melty-cheese masterpiece.
Prepare the Broccoli and Protein Base
Start by cutting the 2.5 lbs broccoli crowns into even florets, keeping the stems intact for structure. In a large skillet, cook the 4 oz optional bacon until crispy, then remove and crumble. In the same pan, sauté the 1 whole yellow onion and 4 cloves garlic cloves until soft and fragrant.
While the vegetables cook, shred the 1 cup American cheese slices into small, even pieces. The key here is to get the cheese finely chopped so it melts smoothly into the casserole. If using the 0.5 cup optional ham, dice it into small cubes now and set aside for later.
Build the Creamy Cheese Sauce
In a separate saucepan, melt the 0.5 cup unsalted butter over medium heat. Whisk in the 0.25 cup all-purpose flour to form a roux, cooking for 2-3 minutes until it turns golden and smells nutty. This is your flavor foundation - don't rush it.
Gradually whisk in the 1 cup heavy cream and 1 cup milk, stirring constantly until smooth. Bring to a gentle simmer, then reduce heat to low. Stir in the 2 cups freshly grated sharp cheddar cheese until completely melted. Season with 1.5 tsp salt and 0.5 tsp black pepper, then remove from heat.
Assemble the Casserole Layers
Preheat your oven to 375°F. In a large greased baking dish (about 9x13 inches), combine the cooked broccoli, sautéed onions, garlic, crumbled bacon, and diced ham. Pour the cheese sauce evenly over the top, spreading it to the edges. Sprinkle the shredded American cheese evenly over the entire surface.
Here's the secret to that perfect crispy top: press down gently on the casserole with a spatula to ensure even contact between the cheese and sauce. This creates that golden, shatteringly crisp crust we all love. Don't skip this step - it makes all the difference.
Create the Crispy Topping
In a small bowl, mix the 0.5 cup panko breadcrumbs with 1 tablespoon melted butter. Spread this mixture evenly over the top of the casserole, pressing down lightly with your fingers. The breadcrumbs will absorb the melted butter and create that signature crunch.
Bake uncovered for 25-30 minutes until the top is golden brown and bubbly, and the cheese is fully melted. The edges should be crispy while the center remains creamy. If the top browns too quickly, tent loosely with foil for the last 5 minutes to prevent burning.
Rest and Serve Perfectly
Remove from the oven and let the casserole rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly and makes it easier to cut clean slices. The casserole will be hot and bubbly - that's exactly what you want.
Cut into squares and serve immediately with a side of garlic bread. The contrast of the crispy top with the creamy, cheesy center is what makes this copycat recipe so special. Leftovers reheat beautifully - just cover with foil and warm in the oven for 10-15 minutes at 350°F.
Pro Tips For Making Cheddars Restaurant Broccoli Cheese Casserole Copycat
- Prep Broccoli in Ice Water: After cutting the florets, plunge them in ice water for 5 minutes—this stops cooking and keeps them crisp. I used to skip this, and the broccoli turned mushy under the cheese sauce. Trust me, the texture difference is noticeable.
- Whisk the Cheese Sauce: Heat the milk and cream together, then whisk in the flour slowly to avoid lumps. After burning through three batches, I finally realized the sauce needs constant stirring—especially when the cheese melts. A wooden spoon works best.
- Don’t Overmix the Baking Dish: Spread the broccoli in a single layer, then pour the sauce over it. Mixing it all together makes the casserole dense. The restaurant version has distinct layers—broccoli stays crisp, cheese stays gooey.
- Use Sharp Cheddar, Not Mild: Sharp cheddar has the tang and melt the recipe expects. Mild cheddar won’t cut through the creaminess. I learned this after a lukewarm first attempt—now I double-check the label.
Dietary considerations for this cheddars restaurant broccoli cheese casserole copycat
Gluten-Free Adaptation
To make this casserole gluten-free, replace the panko breadcrumbs with ½ cup gluten-free breadcrumbs (like Schar or Canyon Bakehouse). For the roux, use ½ cup gluten-free all-purpose flour (like Bob's Red Mill 1-to-1).
The texture will still be crispy, though slightly less golden—add 1 tsp cornstarch to the breadcrumb mix for extra crunch. Always check labels, as some cheeses contain hidden gluten. 🌾
Dairy-Free Options
For a dairy-free version, swap the sharp cheddar for 2 cups dairy-free cheddar shreds (like Violife or Daiya). Replace the heavy cream and milk with 1 cup full-fat coconut milk (for creaminess) and 1 cup unsweetened almond milk.
Use dairy-free butter (like Miyoko's) for the roux. The sauce will be slightly lighter but still rich. Test the seasoning—dairy-free cheeses often need extra salt. 🧀
Lower-Carb Modifications
Cut carbs by replacing ½ cup panko with ½ cup crushed pork rinds (like TenderSuites) for a crispy, zero-carb topping. Swap the broccoli for cauliflower florets (same weight) to reduce net carbs further. Use cream cheese (like Philadelphia) instead of some cheddar to add creaminess without extra carbs.
Keep the sauce base the same—just reduce the flour slightly to ¼ cup + 1 tbsp for a lighter texture. 🥦
Vegetarian-Friendly Swaps
Skip the bacon and ham entirely, or replace them with ½ cup cooked mushrooms (sautéed with garlic) for umami depth. Use nutritional yeast (1 tbsp) in the cheese sauce for a cheesy, vegan-friendly boost.
For extra protein, stir ½ cup cooked lentils into the broccoli layer. The dish stays hearty and satisfying without meat. 🌱
Allergen-Friendly Notes
For nut allergies, ensure all cheeses and breadcrumbs are nut-free (some brands process in nut facilities). If avoiding soy, check labels on cheese substitutes and broths.
For egg-free needs, this recipe is naturally safe—just confirm your cheeses and breadcrumbs contain no egg additives. Always double-check packaging, as cross-contamination risks vary by brand. 💡

Frequently asked questions
Why does my casserole top turn soggy instead of crispy?
Soggy tops happen when moisture escapes during baking. To fix this, press the cheese layer firmly into the sauce before adding breadcrumbs, and make sure your panko mix is dry. Bake at 375°F for 25-30 minutes uncovered, then tent with foil only if needed for the last 5 minutes. Overcrowding the dish also causes steam buildup—use a 9x13-inch pan for best results.
Can I make this ahead of time for a party?
Assemble the casserole up to 24 hours ahead and refrigerate uncovered. When ready to bake, add 10-15 extra minutes to the cooking time since it starts cold. For a crowd, bake it in the morning and keep it warm in a 200°F oven until serving. The flavors deepen overnight, making it even more delicious.
What's the best cheese substitute if I can't find sharp cheddar?
For closest results, blend Monterey Jack with Colby Jack (50/50 ratio) or use White Cheddar for extra tang. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. If you're dairy-free, Violife or Daiya cheddar shreds work well when combined with coconut milk.
How do I prevent the cheese sauce from getting watery?
Watery sauce happens when cheese doesn't melt fully or the roux isn't cooked long enough. Always cook the roux until golden (2-3 minutes) before adding liquids, and stir constantly while melting the cheese. For extra insurance, thicken with 1 tsp cornstarch mixed with 1 tbsp cold water and stirred in at the end.
Can I add other vegetables to this recipe?
Yes! Try adding ½ cup diced bell peppers or ½ cup corn kernels to the broccoli layer for extra veggies. Avoid watery vegetables like zucchini or tomatoes—they'll dilute the sauce. For heartier versions, mix in ½ cup cooked quinoa or ½ cup diced potatoes (parboiled first). Always drain well to maintain texture.
