Broccoli Cheese Casserole Ingredients
For the Casserole
- Broccoli Florets – This is the star of our dish, providing a deliciously nutritious bulk. Feel free to substitute with cauliflower for a different twist.
- Extra-Virgin Olive Oil – Adds richness and flavor during the sautéing process. Butter can also be used for a lovely rich alternative.
- Leeks – These aromatic beauties infuse a subtle sweetness, enhancing the overall flavor profile. If leeks are hard to find, yellow onion is a decent substitute in a pinch.
- Chopped Shallots – Boosts the depth of flavor in the casserole. You can use extra leeks or onion if shallots are missing.
- Minced Garlic – A must for that aromatic kick. In case you run out of fresh garlic, garlic powder works as a stand-in.
- Dry White Wine – Adds a touch of acidity to balance the richness of the cheese sauce. Mixing vegetable or chicken broth with sherry vinegar makes a good substitution (5 Tbsp broth + 1 Tbsp vinegar).
- All-Purpose Flour – This thickens our creamy sauce to perfection. Gluten-free flour is a wonderful option for a gluten-free dish.
- Whole Milk – Provides the smooth creaminess we crave in a casserole. Unsweetened cashew milk is a great dairy-free alternative.
- Kosher Salt and Black Pepper – Simple seasoning that elevates everything. Feel free to adjust the amount according to your personal taste.
- White Cheddar Cheese – The key player for that creamy, sharp flavor. Any favorite melting cheese such as Gruyere can step in if needed.
For the Topping
- Panko Breadcrumbs – These create a delightful crunchy topping. You can use regular breadcrumbs, but for ultimate crunch, panko is preferred.

Step‑by‑Step Instructions for Broccoli Cheese Casserole
Step 1: Steam the Broccoli
Begin by steaming the broccoli florets until they are crisp-tender, which should take about 5 minutes. You can use a microwave-safe bowl with a lid or a stovetop steamer. Once done, drain them thoroughly and set aside to let them cool slightly while you prepare the cheese sauce.
Step 2: Preheat the Oven
Preheat your oven to 425°F (220°C) and ready an 11×7-inch baking pan by greasing it lightly with cooking spray or olive oil. This will ensure the casserole doesn’t stick and will help achieve that gorgeous golden crust.
Step 3: Sauté the Aromatics
In a large skillet, heat 2 tablespoons of extra-virgin olive oil over medium-high heat. Add the chopped leeks and shallots, cooking for about 8 to 10 minutes until they are softened and fragrant. Stir occasionally to ensure even cooking and prevent browning.
Step 4: Add Garlic
Next, stir in the minced garlic and cook for an additional 1 to 2 minutes, until it becomes aromatic. The garlic will release its delicious fragrance, enhancing the overall flavor profile of your Broccoli Cheese Casserole.
Step 5: Incorporate the Wine
Pour in the dry white wine, allowing it to simmer for 2 to 3 minutes, or until most of the liquid has evaporated. This step adds depth to the sauce and deglazes the pan, capturing all those lovely bits of flavor.
Step 6: Thicken the Sauce
Sprinkle the all-purpose flour over the mixture, stirring constantly for about 1 to 2 minutes until everything is well coated. This will help thicken your cheese sauce later, ensuring a rich and creamy texture in the casserole.
Step 7: Whisk in the Milk
Slowly whisk in the whole milk, bringing the mixture to a simmer. Cook for about 4 to 5 minutes, stirring frequently until the sauce thickens and coats the back of a spoon. Add salt, pepper, and the white cheddar cheese, stirring until everything is melted and smooth.
Step 8: Fold in the Broccoli
Remove the skillet from the heat and gently mix in the steamed broccoli florets until they are evenly coated with the cheese sauce. This delightful combination of creamy sauce and broccoli is the heart of your Broccoli Cheese Casserole!
Step 9: Transfer to Baking Dish
Pour the broccoli and cheese mixture into the prepared baking dish, spreading it out evenly. This step ensures every portion gets an equal amount of deliciousness in your casserole, ready to be topped.
Step 10: Prepare the Panko Topping
In a small bowl, mix the remaining olive oil with the panko breadcrumbs until they are well coated. Sprinkle this golden topping generously over the casserole to create that irresistible crispy texture that every good broccoli cheese casserole needs.
Step 11: Bake the Casserole
Place the casserole in the preheated oven and bake uncovered for about 20 minutes, or until the panko is golden brown and the casserole is bubbling. Keep an eye on it to avoid burning; if needed, cover with foil during the last few minutes of baking.
Step 12: Serve and Enjoy
Once baked, remove the Broccoli Cheese Casserole from the oven and let it cool for a few minutes. Serve warm, and let the creamy, cheesy goodness warm the hearts of your loved ones at your next gathering or weeknight dinner!

What if my cheese sauce is too thin?
If your sauce seems a bit too runny, don’t panic! Simply return it to the stovetop over medium heat. Whisk continuously for about 2-3 minutes until it thickens to your desired consistency. If needed, you can sprinkle a bit more flour to help thicken it further. This approach ensures you’ve got that creamy goodness enveloping your broccoli!
Are there any dietary considerations for this recipe?
Definitely! This Broccoli Cheese Casserole can be modified to suit various dietary needs. For a gluten-free dish, simply substitute regular flour with a gluten-free blend.
