Ingredients
- 2 pounds fresh broccoli florets, cut into bite-sized pieces
- 3 cups sharp cheddar cheese, freshly grated (divided)
- 1 cup whole milk
- 1/2 cup heavy cream
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 1 medium onion, finely diced
- 2 cloves garlic, minced
- 1 cup panko breadcrumbs
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon paprika
Instructions
- Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish.
- Blanch the broccoli in boiling water for 3-4 minutes until bright green and barely tender. Immediately transfer to an ice bath to stop the cooking process.
- In a large saucepan, melt 2 tablespoons of butter over medium heat. Add onions and cook until translucent (about 5 minutes), then add garlic and cook for another minute.
- Sprinkle flour over the butter mixture and whisk constantly for 1 minute to create a roux.
- Gradually pour in milk and cream while whisking continuously to prevent lumps. Cook until the sauce thickens, about 3-4 minutes.
- Remove from heat and stir in 2 cups of cheddar cheese until melted. Season with salt, pepper, and paprika.
- Combine the sauce with the drained broccoli and transfer to the prepared baking dish.
- Mix remaining cheese with panko breadcrumbs and melted butter, then sprinkle over the casserole.
- Bake for 25-30 minutes until golden brown and bubbly.

Recipe Notes
For best results, keep these helpful tips in mind:
- Don’t skip the blanching step – it ensures your broccoli maintains its bright color and perfect texture.
- Grate your own cheese rather than using pre-shredded varieties. Fresh-grated cheese melts more smoothly and provides better flavor.
- Make sure to drain the blanched broccoli thoroughly to prevent a watery casserole.
- The casserole can be assembled up to 24 hours in advance and refrigerated before baking.
- For a gluten-free version, substitute the flour with cornstarch and use gluten-free breadcrumbs.
- Leftovers will keep well in an airtight container for up to 3 days in the refrigerator.
