Ingredients
Vegetables & Aromatics
- 4 cups fresh broccoli florets
- 1 small yellow onion, diced
- 2 cloves garlic, minced
Dairy & Butter
- 2 tablespoons unsalted butter
- 1 cup whole milk
- 1/2 cup heavy cream
- 2 cups shredded sharp cheddar cheese, divided
- 1 tablespoon melted butter
Dry Ingredients & Seasonings
- 2 tablespoons all-purpose flour
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon ground mustard (optional)
- 1 1/2 cups mini garlic butter pretzels, lightly crushed
Garnish
- 1 tablespoon chopped fresh parsley (optional)
Instructions
- Preheat and prepare dish: Preheat your oven to 375°F (190°C) and lightly grease a 9×9-inch or similar-sized baking dish to ensure the casserole doesn’t stick.
- Steam the broccoli: Steam or blanch the broccoli florets for 2 to 3 minutes until they are just tender but still bright green, then drain well and set aside; this prevents mushy texture later in the bake.
- Cook aromatics: In a medium saucepan, melt 2 tablespoons butter over medium heat. Add the diced onion and cook for 3 to 4 minutes until softened and translucent. Stir in the minced garlic and cook for an additional 30 seconds to release its aroma.
- Make the roux: Whisk in the all-purpose flour and cook the mixture for 1 minute to form a roux, which will thicken the sauce.
- Prepare cheese sauce: Gradually whisk in the whole milk and heavy cream until smooth. Continue cooking and stirring frequently until the sauce thickens, about 3 to 5 minutes. Season with salt, black pepper, and optional ground mustard.
- Add cheese: Remove from heat and stir in 1 1/2 cups of the shredded cheddar cheese until melted and the sauce is smooth and creamy.
- Combine broccoli and sauce: Add the steamed broccoli to the cheese sauce and stir gently to evenly coat all the florets.
- Assemble casserole: Pour the broccoli and cheese mixture into the prepared baking dish, spreading it out evenly.
- Prepare topping: In a small bowl, toss the lightly crushed garlic butter pretzels with melted butter to coat them well.
- Add finishing touches: Sprinkle the remaining 1/2 cup cheddar cheese over the broccoli casserole, then evenly distribute the pretzel mixture on top for a crunchy crust.
- Bake: Place the casserole in the preheated oven and bake for 18 to 22 minutes until bubbly and golden on top.
- Garnish and serve: Remove from the oven and garnish with chopped fresh parsley if desired before serving warm.
Notes
- For added protein, stir in 1 cup of cooked shredded chicken or cooked quinoa before baking.
- Use store-bought garlic butter pretzel bites or twist-style pretzels, lightly crushed for topping crunch.
- Avoid overcooking the broccoli before baking to keep it from becoming mushy and maintain texture.
