Step‑by‑Step Instructions for Creamy Broccoli Cheddar Casserole with Garlic Butter Pretzels
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven is warming up, take a moment to grease a 9×13 inch casserole dish with a bit of olive oil or non-stick spray, ensuring it’s ready for your delicious broccoli cheddar casserole once it’s assembled.
Step 2: Roast the Broccoli
In a large bowl, toss the fresh or thawed broccoli florets with olive oil, salt, and pepper until well-coated. Spread the seasoned broccoli evenly on a baking sheet and roast in the preheated oven for about 15 minutes. You’ll know it’s done when the florets are tender and slightly golden, enhancing their natural flavor.
Step 3: Sauté Onion and Garlic
While the broccoli is roasting, melt 4 tablespoons of unsalted butter in a large saucepan over medium heat. Once melted, add the diced onion and sauté for 3-4 minutes until it becomes soft and translucent. Next, stir in the minced garlic, cooking for an additional 30 seconds until fragrant but careful not to brown it.
Step 4: Make the Roux
Next, sprinkle in the all-purpose flour, stirring constantly for about 1-2 minutes to create a roux. This mixture will help thicken your creamy broccoli cheddar casserole sauce. As you stir, watch for the flour to turn a light golden color, signaling it’s ready for the next step.
Step 5: Prepare the Cheese Sauce
Gradually whisk in 2 cups of whole milk, stirring continuously until the mixture is smooth and free of lumps. Continue cooking over medium heat for about 5 minutes, or until the sauce thickens to the texture of heavy cream. It should coat the back of a spoon when it’s ready.
Step 6: Add Cheddar and Seasonings
Once thickened, remove the saucepan from the heat and stir in 2 cups of shredded cheddar cheese, a pinch of cayenne pepper, and a teaspoon of Dijon mustard. Mix until the cheese has completely melted, yielding a rich and creamy sauce for your broccoli cheddar casserole.
Step 7: Fold in Broccoli and Sour Cream
Now, gently fold in the roasted broccoli and 1 cup of sour cream into the cheese sauce. Ensure everything is coated evenly, letting the broccoli absorb the luscious cheesy flavors. The blend of cheesy goodness and tender broccoli creates the heart of your comforting casserole.
Step 8: Assemble the Casserole
Pour the creamy broccoli mixture into the greased casserole dish, spreading it evenly across the bottom. For a perfect finish, sprinkle a generous layer of crushed garlic butter pretzel pieces on top, providing a satisfying crunch and enhancing the flavors of the creamy broccoli cheddar casserole.
Step 9: Bake to Perfection
Place your assembled casserole in the preheated oven and bake for 20-25 minutes. Keep an eye on it as it cooks; it’s ready when the top is golden brown and the edges are bubbly, filling your kitchen with the irresistible aroma of comfort food.
Step 10: Let it Rest
After baking, remove the casserole from the oven and allow it to sit for a few minutes. This resting time helps the casserole set perfectly for serving. The crunchy pretzel topping will maintain its delightful texture while the cheesy filling remains warm and inviting for every delicious bite.
Expert Tips for Broccoli Cheddar Casserole
-
Whisk Gradually: Slowly whisk the milk into the roux to prevent lumps. This ensures a perfectly smooth cheese sauce throughout your broccoli cheddar casserole.
-
Watch the Garlic: Sauté garlic until just fragrant; overcooking can make it bitter. A perfectly cooked garlic enhances the overall flavor of your dish.
-
Rest Before Serving: Allow your casserole to sit for a few minutes post-baking. This resting time helps it set, making for cleaner servings and a better texture.
-
Topping Texture: Use freshly crushed garlic butter pretzels for an extra crunch. Pre-packaged options might lack the same flavor punch and moisture balance.
-
Flavor Experiment: Feel free to add spices! A pinch of cayenne adds a delightful kick, but don’t shy away from experimenting with your favorite seasonings in the broccoli cheddar casserole.

Creamy Broccoli Cheddar Casserole with Garlic Butter Pretzels Recipe FAQs
What type of broccoli should I use?
Absolutely! You can use either fresh or frozen broccoli florets for this recipe. If you opt for frozen, be sure to thaw and drain them well before tossing them with olive oil. Fresh broccoli will deliver a vibrant crunch, while frozen will work just fine if you’re short on time.
How should I store leftover casserole?
Leftover broccoli cheddar casserole can be stored in an airtight container in the refrigerator for up to 3 days. Just make sure to let it cool first before sealing it in! I recommend reheating it in the oven to keep that amazing crunchy pretzel topping intact.

Why is my cheese sauce lumpy?
Lumpy cheese sauce can happen if the milk is added too quickly into the roux. Make sure to whisk the milk in gradually to create a smooth mixture. If you find that it’s already lumpy, try blending it with an immersion blender to help smooth it out before you fold in the broccoli.
