Step‑by‑Step Instructions for Creamy Broccoli Cheddar Casserole with Garlic Butter Pretzels
Step 1: Preheat and Prepare Dish
Begin by preheating your oven to 375°F (190°C). While the oven heats up, grab a 9×13 inch casserole dish and lightly grease it with cooking spray or butter to prevent sticking. This simple prep step ensures your broccoli cheddar casserole will bake to perfection without any hassle.
Step 2: Roast the Broccoli
In a large bowl, toss the fresh broccoli florets with olive oil, salt, and pepper until evenly coated. Spread the broccoli in a single layer on a lined baking sheet, and roast it in the preheated oven for about 15 minutes. Look for the florets to become tender and slightly charred, enhancing their natural sweetness for the casserole.
Step 3: Sauté the Aromatics
While the broccoli roasts, melt 4 tablespoons of unsalted butter in a saucepan over medium heat. Once melted, add the diced onion and sauté for 3-4 minutes until it’s soft and translucent. The warm aroma will fill your kitchen, setting the perfect stage for your creamy sauce.
Step 4: Add Garlic
Next, stir in the minced garlic and sauté for an additional 30 seconds until fragrant. Be careful not to let the garlic burn, as this could create a bitter note. This step will infuse your sauce with rich, savory flavors that complement the broccoli.
Step 5: Create the Roux
Sprinkle in ¼ cup of all-purpose flour and whisk continuously for about 1-2 minutes to form a roux. This mixture will help thicken the sauce. Look for it to become slightly golden, which indicates it’s ready for the next step.
Step 6: Make the Cheese Sauce
Gradually pour in 2 cups of whole milk, continuing to whisk until the mixture thickens and is smooth, about 3-5 minutes. Once it starts bubbling gently, stir in 2 cups of shredded cheddar cheese along with cayenne pepper and Dijon mustard, allowing it to melt beautifully for a creamy base.
Step 7: Combine with Broccoli
Once the cheese has melted, gently fold in 1 cup of sour cream and the roasted broccoli, ensuring everything is evenly mixed. The creamy mixture should envelop the broccoli, making it a true broccoli cheddar casserole delight, bursting with flavor and a touch of tang.
Step 8: Assemble the Casserole
Pour the prepared broccoli mixture into the greased casserole dish, smoothing it out evenly with a spatula. Now, sprinkle crushed garlic butter pretzel pieces generously on top for a delightful crunch. This topping will add a wonderful contrast to the creamy casserole beneath.
Step 9: Bake
Place the casserole in the oven and bake for 20-25 minutes, or until the top is golden brown and the casserole is bubbling. Keep an eye on it towards the end to avoid over-browning. The beautiful, crispy pretzel topping will invite everyone to gather around the table.
Step 10: Rest Before Serving
Once baked, remove the casserole from the oven and let it rest for about 5 minutes before serving. This allows the flavors to meld and the dish to set slightly, making it easier to serve. Then, enjoy the comforting goodness of your broccoli cheddar casserole with garlic butter pretzels!
