How to Make Creamy Broccoli Cheddar Casserole with Garlic Butter Pretzels Recipe
Step 1: Prepare the Broccoli
Start by steaming or blanching the broccoli florets until they’re crisp-tender but still vibrant green. Fresh broccoli will give the best texture but frozen is a wonderful time-saver. Drain well and set aside – no one likes soggy broccoli in their casserole!
Step 2: Make the Creamy Cheese Sauce
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for about a minute to eliminate the raw flour taste. Slowly pour in the milk or half-and-half, whisking constantly to avoid lumps. Bring to a gentle simmer; the sauce will thicken beautifully. Stir in the shredded sharp cheddar cheese until melted and silky. Add garlic powder, onion powder, salt, pepper, Dijon mustard, and crushed red pepper flakes if using. Taste and adjust seasoning as needed.
Step 3: Combine Broccoli and Cheese Sauce
Transfer the steamed broccoli to a large mixing bowl and pour the creamy cheese sauce over it. Gently toss everything together so every broccoli piece is coated with that luscious, cheesy goodness.
Step 4: Prepare the Garlic Butter Pretzel Topping
In a small bowl, mix the melted butter with the minced garlic and a pinch of salt. Toss the mini or crushed pretzels in this fragrant butter mixture until fully coated. This step will infuse the topping with rich garlic flavor and ensure maximum crunch.
Step 5: Assemble and Bake
Spread the broccoli and cheese mixture into a greased casserole dish. Evenly sprinkle the garlic butter pretzels on top. Bake in a preheated oven at 350°F (175°C) for about 25-30 minutes, until bubbly and golden on top. Let it rest a few minutes before serving to allow the sauce to settle.
How to Serve Creamy Broccoli Cheddar Casserole with Garlic Butter Pretzels Recipe
Garnishes
Fresh parsley sprinkled on top adds a pop of color and a fresh herbaceous note that cuts through the richness beautifully. For extra indulgence, a light drizzle of hot sauce or a spoonful of sour cream makes for exciting finishers you can offer at the table.
Side Dishes
This casserole is hearty enough to be the star of the meal, but it also pairs wonderfully with simple sides like a crisp green salad dressed with lemon vinaigrette or roasted garlic mashed potatoes. For a lighter option, steamed or sautéed green beans make a perfect balance.
Creative Ways to Present
For a fun twist, serve individual portions in ramekins with mini pretzel sticks alongside for nibbling. You can also turn the casserole into a comforting potluck dish by layering it in a deep dish and letting the crunchy garlic pretzel topping shine as conversation starter and the ultimate crowd-pleaser.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and refrigerate for up to 3 days. The creamy broccoli cheddar casserole will thicken after chilling, but the flavors will deepen, offering an even tastier second round.
Freezing
This casserole freezes well before baking. Assemble it completely, cover tightly with foil or plastic wrap, and freeze for up to 3 months. To bake from frozen, add 10-15 extra minutes to the baking time and bake covered until warmed through, uncovering near the end to crisp the pretzel topping.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until hot and bubbly, about 15-20 minutes. To keep the garlic butter pretzel topping crispy, add a sprinkle of fresh crushed pretzels after reheating or briefly broil for a minute or two with close attention.
FAQs
Can I use other cheeses besides cheddar in this casserole?
Absolutely! While sharp cheddar gives this dish its iconic flavor, you can substitute with Monterey Jack, Gouda, or a mix of cheeses to create different taste profiles. Just be sure to choose a cheese that melts well.
Is it necessary to use fresh broccoli, or can I use frozen?
Both work wonderfully. Fresh broccoli offers a bit more texture and color, but frozen broccoli is a convenient and equally tasty shortcut. Just make sure to thaw and drain frozen broccoli well before mixing into the casserole.
Can I make the garlic butter pretzel topping ahead of time?
Yes! You can toss the pretzels in garlic butter up to a day before baking. Keep them covered at room temperature so they stay crunchy. This saves time on baking day and still delivers that fabulous flavor.
Is this casserole suitable for freezing after it has been baked?
It’s best to freeze before baking for optimal texture, but baked leftovers can be frozen as well. Just understand the pretzel topping may lose some crunch after freezing and reheating.
What can I do to make this dish spicier?
Add extra crushed red pepper flakes to the cheese sauce or sprinkle cayenne pepper into the garlic butter pretzel topping for a fun spicy kick that complements the creaminess perfectly.

Ingredients
Broccoli

Cheese Sauce
- 2 tablespoons butter
- 1/4 cup all-purpose flour
- 2 cups whole milk (or half-and-half for a richer sauce)
- 2 cups shredded sharp cheddar cheese
- 1/2 teaspoon garlic powder
- 1/4 teaspoon onion powder
- Salt and pepper, to taste
- 1/2 teaspoon Dijon mustard (optional, for extra depth of flavor)
- 1/4 teaspoon crushed red pepper flakes (optional, for heat)
Garlic Butter Pretzel Topping
- 2 cups mini pretzels or crushed pretzels
- 2 tablespoons butter, melted
- 2 cloves garlic, minced
- 1 tablespoon chopped fresh parsley (optional)
- Salt, to taste
Instructions
- Prepare the Broccoli: If using fresh broccoli, steam or blanch the florets until tender-crisp, about 3-4 minutes. If using frozen, thaw and drain well to remove excess moisture.
- Make the Cheese Sauce: In a medium saucepan over medium heat, melt 2 tablespoons of butter. Whisk in the flour and cook for 1-2 minutes to form a roux without browning. Gradually whisk in the milk or half-and-half, continuing to whisk until the mixture thickens, about 5-7 minutes. Remove from heat and stir in shredded cheddar cheese until melted and smooth. Add garlic powder, onion powder, Dijon mustard (if using), crushed red pepper flakes (if using), and season with salt and pepper to taste.
- Combine Broccoli and Sauce: In a large mixing bowl, combine the cooked broccoli with the cheese sauce, folding gently to evenly coat all florets.
- Prepare the Garlic Butter Pretzels: In a small bowl, mix the melted butter with minced garlic and chopped parsley (if using). Toss the mini pretzels or crushed pretzels in the garlic butter mixture until evenly coated. Sprinkle lightly with salt if desired.
- Assemble the Casserole: Transfer the broccoli and cheese mixture to a greased 9×13 inch baking dish. Evenly spread the garlic butter pretzels over the top to create a crunchy topping.
- Bake the Casserole: Preheat the oven to 350°F (175°C). Bake the casserole uncovered for 25-30 minutes, or until the topping is golden brown and the cheese sauce is bubbly.
- Serve: Remove from the oven and let sit for a few minutes before serving to allow the casserole to set slightly. Enjoy warm as a delicious side or light main dish.
Notes
- For a gluten-free option, substitute the all-purpose flour with a gluten-free flour blend and use gluten-free pretzels.
- You can prepare this casserole a day ahead; assemble it and refrigerate, then bake when ready to serve.
- Adjust the heat by omitting or increasing the crushed red pepper flakes to suit your taste.
- For a richer sauce, use half-and-half instead of whole milk.
- To add more protein, consider stirring in cooked chicken or bacon before baking.
