Ingredients
- 4 cups fresh broccoli florets (about 2 medium heads)
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup whole milk
- 1/2 cup shredded sharp cheddar cheese
- 1/4 cup grated Parmesan cheese
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon garlic powder
- 1/2 cup panko breadcrumbs
- 1 tablespoon olive oil
How to make it
- Bring a large pot of salted water to a rolling boil over high heat. Add the broccoli florets and cook for exactly 2 minutes until they turn bright green and are just tender.
- Immediately drain them in a colander and run cold water over the florets to stop the cooking process. Let the broccoli drain well.
- In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1 minute, stirring constantly, until the mixture is golden and smells nutty.
- Slowly pour in the milk while whisking vigorously to avoid lumps. Continue whisking until the sauce thickens enough to coat the back of a spoon, about 3 to 4 minutes. Remove from heat and stir in the cheddar cheese, Parmesan cheese, salt, pepper, and garlic powder until smooth and fully melted.
- In a small skillet, heat the olive oil over medium heat. Add the panko breadcrumbs and stir constantly for 2 to 3 minutes until they turn golden brown and fragrant. Remove from heat and set aside.
- Preheat your oven to 375°F. Spread the blanched broccoli florets evenly in an 8×8-inch baking dish. Pour the cheese sauce over the broccoli, making sure every floret gets coated. Use a spatula to gently toss the broccoli with the sauce so everything is well combined.
- Sprinkle the toasted breadcrumbs evenly over the top of the casserole. Place the dish in the preheated oven and bake for 15 to 18 minutes, until the sauce is bubbly around the edges and the topping is deep golden brown.
- Let the casserole rest for 5 minutes before serving.
How to serve it
Serve Grandma’s Best Broccoli Casserole warm as a side dish or a main meal. Pair it with roasted meats or a fresh salad for a complete meal. It’s also a wonderful addition to any potluck or family gathering.
How to store it
Once cooled, cover the casserole tightly with plastic wrap or transfer it to an airtight container. You can store it in the refrigerator for up to 3 to 4 days. Reheat in the oven or microwave until heated through.
Helpful tips
- For best results, use fresh broccoli rather than frozen, as fresh will provide a better texture.
- Make sure to whisk the sauce continuously while adding the milk to ensure a smooth consistency.
- Let the casserole sit for a few minutes after baking; this allows it to set and makes serving easier.
Optional variations
- Add cooked chicken or turkey for a heartier main dish.
- Mix in other vegetables, such as cauliflower or carrots, for added color and nutrients.
- Use different cheeses like mozzarella or gouda for a unique flavor.
Frequently asked questions
Can I make this casserole ahead of time?
Yes! You can prepare the casserole up to the baking step, cover it, and store it in the refrigerator for up to 24 hours. When ready to bake, just pop it in the oven.
Can I freeze the casserole?
Yes, this casserole can be frozen. Make sure to cool it completely before wrapping it tightly to prevent freezer burn. It will keep for about 2 months. Thaw in the refrigerator overnight before reheating.
What can I substitute for panko breadcrumbs?
You can use regular breadcrumbs if you don’t have panko, but they may not be as crispy. If you want a gluten-free option, there are gluten-free breadcrumbs available that work just as well.
