Ingredient notes

Broccoli: Fresh florets work best for this recipe to give it a perfect texture, but frozen broccoli can be used if thawed and patted dry to prevent extra moisture.
Milk: Whole milk creates the creamiest sauce, but you can use 2% if that’s what you have on hand. Avoid skim milk, as it may result in a thinner sauce.
Cheese: A mix of sharp cheddar and Parmesan adds depth, but you can swap in Gruyère or Monterey Jack for a twist. Pre-shredded cheese is perfectly fine, but freshly shredded melts more smoothly.
Crackers: Buttery round crackers give the topping its signature crunch, but panko breadcrumbs or crushed pretzels can be a great substitute if needed.

How to make broccoli casserole from scratch

Let’s get started on this cozy broccoli cheese casserole—it’s made from scratch and packed with cheesy, creamy goodness. Trust me, once you try this, it’s going to become a favorite in your kitchen!

1. Before you begin: First, preheat your oven to 360°F and grease a 9×13-inch baking dish. A light coat of butter or non-stick spray will do the trick, making cleanup a breeze later. If your oven preheats fast, you may turn it on later – just don’t forget!

2. Prep broccoli: Next, bring a large pot of salted water to a boil. Toss in the broccoli florets and let them cook for just 3 to 5 minutes. You’re looking for them to be firm but starting to get tender. No mushy broccoli here!

Once they’re ready, drain them immediately and give them a quick rinse under cold water to stop the cooking process. This little trick keeps them bright green and perfectly crisp-tender.

3. Make the sauce: Now, let’s make that delicious, from-scratch cheese sauce. Grab a medium saucepan and melt the butter over medium heat. Once it’s melted, add the diced onion and let it cook gently, stirring often, until it’s soft and fragrant. This should take about 7 to 8 minutes. Be patient here—soft onions without browning are the goal!

Reduce the heat to medium-low and sprinkle the flour over the onions. Stir constantly for about 2 minutes. You’re creating a roux, which will help thicken the sauce.

Slowly pour in the milk, whisking as you go. Don’t rush this step—whisking gradually ensures a smooth, lump-free sauce. Once the milk is fully incorporated, stir in the salt, garlic powder, and a little black pepper.

Turn the heat back up to medium-high and keep whisking. In just a minute or two, the sauce will start to bubble and thicken. It’s magic! Once it’s thick and glossy, remove the saucepan from the heat.

4. Finish sauce: Now for the fun part: stir in the diced cream cheese and shredded cheeses. Keep stirring until everything is melted and you have a luscious, creamy cheese sauce that smells heavenly.

5. Assemble: Spread about ¼ of the cheese sauce over the bottom of your prepared baking dish. This creates a nice base layer to coat the broccoli.

Add half of the cooked broccoli on top, spreading it out evenly. Pour half of the remaining cheese sauce over the broccoli, making sure it gets into all the nooks and crannies.

Repeat with the rest of the broccoli and cheese sauce. Finally, sprinkle ¼ cup of shredded cheddar over the top for that extra layer of cheesiness.

Now, for the finishing touch: the buttery, crunchy topping. In a small bowl, combine the crushed crackers with the melted butter, then sprinkle the mixture evenly over the top of the casserole. It’s going to bake up beautifully golden and crispy.

6. Bake: Pop the casserole into your preheated oven and bake for 15 to 20 minutes. You’ll know it’s ready when the sauce is bubbly and the topping is golden and irresistible. Let it rest on the counter for 5 to 10 minutes before serving—this helps everything set so it’s easier to scoop.

And there you have it! A warm, creamy, homemade broccoli cheese casserole that’s perfect for any occasion. Serve it as a comforting side dish or a main course everyone will love. Enjoy!

Top tips for recipe success

Keep an eye on the oven: Ovens can vary, so start checking your casserole a few minutes early to prevent the topping from burning. If it’s browning too quickly, loosely cover it with foil for the rest of the bake time.
Customize your cracker topping: If you prefer a chunkier crunch, leave the cracker crumbs a bit larger. For a finer, more even topping, crush them into smaller pieces—it’s all about your personal preference!
Take your time with the sauce: Don’t rush the cheese sauce; whisking slowly ensures a smooth, creamy consistency without lumps. Cooking the flour and butter (the roux) for the full two minutes adds depth of flavor and eliminates any raw flour taste.
Broccoli prep: Cutting the broccoli into bite-sized pieces helps them cook evenly and makes the casserole easier to serve and eat.
Blanch, don’t overcook the broccoli: Boil the broccoli just until crisp-tender and stop the cooking with a cold rinse. This keeps it vibrant and prevents it from becoming mushy.
Freshly shredded cheese melts best: While pre-shredded cheese is convenient, it often contains anti-caking agents that can make your sauce grainy. Shredding cheese fresh will give you a smoother, creamier result.
Let it rest before serving: Give the casserole 5-10 minutes to cool after baking. This helps the layers set and makes serving easier.

Helpful recipe hints

Recipe variations

Add protein: Stir in cooked, diced chicken, diced ham or crumbled bacon for a heartier version that can double as a main dish.
Try different veggies: Swap broccoli for cauliflower, or mix in carrots, peas, or sautéed mushrooms for a colorful twist.
Switch up the cheese: Experiment with Gruyère, Gouda, or Monterey Jack for a different flavor profile. A smoky cheddar can also add a bold touch.
Go low-carb: Skip the cracker topping and use crushed pork rinds or grated Parmesan for a crunchy, keto-friendly option.
Make it spicy: Add a pinch of cayenne pepper or red pepper flakes to the cheese sauce for a subtle kick of heat.
Herb it up: Stir in fresh herbs like thyme or parsley to the sauce for an extra layer of flavor.

Storage tips

Make ahead: You can prepare the casserole up to the point of baking (minus the cracker topping!), cover it tightly with plastic wrap or foil, and refrigerate for up to 24 hours.

When ready to bake, let it sit at room temperature for 15-20 minutes, then add the cracker topping and bake as directed.

Leftover storage: Since this casserole contains dairy, it’s best not to leave it out at room temperature for more than 2 hours to keep it safe to eat!

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the whole dish in the oven at 350°F until heated through.

Freezer storage: To freeze, assemble the casserole but skip the cracker topping and the baking step. Cover it tightly with a layer of plastic wrap and foil, then label with the name and use-by date and freeze for up to 2 months.

When ready to bake, thaw overnight in the refrigerator, remove the plastic wrap and foil, add the cracker topping and bake as directed.
