Making the Ultimate Roasted Cauliflower Cheese is a straightforward process that yields a rich and flavorful dish perfect for any occasion. Here’s a step-by-step guide to help you prepare this delicious recipe from start to finish:

Step 1: Prepare the Cauliflower

1. Preheat your oven to 400°F (200°C).
2. Wash the cauliflower thoroughly and trim the leaves and stem.
3. Cut the cauliflower into bite-sized florets, making sure they’re all similar in size to ensure even cooking.
4. Place the cauliflower florets on a large, rimmed baking sheet. Drizzle them with olive oil, and sprinkle with salt and pepper. Toss the cauliflower around to ensure it’s evenly coated in the oil and seasoning.

Step 2: Roast the Cauliflower

1. Roast the cauliflower in the preheated oven for 20-25 minutes, stirring halfway through the cooking time. The cauliflower should become tender and golden brown with crispy edges.
2. Once done, remove the baking sheet from the oven and set aside. The cauliflower is now ready to be combined with the cheese sauce.

Step 3: Make the Cheese Sauce

1. While the cauliflower is roasting, start making the cheese sauce. In a medium saucepan, melt the butter over medium heat.
2. Once the butter is melted, add the flour and whisk continuously to form a smooth roux. Cook for about 1-2 minutes, being careful not to let it brown.
3. Gradually pour in the milk, whisking constantly to prevent lumps from forming. Continue to cook the mixture, whisking occasionally, until it thickens and begins to simmer, about 4-5 minutes.
4. Once the sauce has thickened, reduce the heat to low and add in the shredded cheddar cheese and grated parmesan cheese. Stir the sauce until the cheeses melt completely and the sauce becomes smooth and creamy.
5. Taste the sauce and adjust the seasoning with salt, pepper, garlic powder, and mustard powder, if using. Once it’s seasoned to your liking, remove the sauce from the heat.

Step 4: Combine the Cauliflower and Cheese Sauce

1. Pour the cheese sauce over the roasted cauliflower florets on the baking sheet or transfer the cauliflower to a large mixing bowl. Gently toss the cauliflower with the sauce until each floret is well coated.
2. If you prefer a crispier topping, transfer the cauliflower and cheese mixture into a casserole dish and sprinkle the panko breadcrumbs and a little extra cheese on top.

Step 5: Optional – Bake for a Crispy Topping

1. If you’re adding the breadcrumb topping, place the casserole dish back in the oven and bake for an additional 10-12 minutes, or until the top is golden brown and bubbly.
2. If you like your dish extra cheesy, you can also add some more shredded cheese to the top before baking.

Step 6: Serve and Enjoy

1. Once the cauliflower is golden and bubbly, remove the dish from the oven. If desired, garnish with fresh herbs like parsley or thyme for added color and flavor.
2. Serve the Ultimate Roasted Cauliflower Cheese as a main dish or as a side with your favorite protein or salad. It’s perfect for family dinners, special occasions, or even as a delicious comfort food option for yourself!
