Instructions
Preheat oven to 425°F.
Prepare the Cauliflower. Add cauliflower florets to a 13 by 9-inch baking dish along with 2 tablespoons of oil, ½ teaspoon salt, and ¼ teaspoon black pepper. Toss to combine and spread cauliflower out in the dish. Bake in preheated oven for 15-20 minutes.
1 large head cauliflower, 2 tablespoons oil, 1 teaspoon salt, ¼ teaspoon black pepper
Make the Sauce. While cauliflower is baking, add 2 tablespoons of butter and crushed garlic to a large skillet or saucepan. Sauté over medium heat for 1 minute. Sprinkle flour into the pan and whisk for 1-2 minutes, or until it begins to form a paste. Reduce heat to medium-low. Pour in room-temperature milk, ¼ cup at a time, whisking well after each addition. Wait to add the next amount until the sauce has thickened.
Add Cheese and Cauliflower. Once all of the milk is added, turn off the heat and mix in gruyere cheese, ¼ cup Parmesan cheese, ½ teaspoon salt, thyme, and coriander. Pour sauce over baked cauliflower and toss to combine.
1 teaspoon salt, ¾ cup cheese, ½ cup grated Parmesan cheese, ¼ teaspoon dried thyme, ¼ teaspoon coriander
Top and Bake. Mix together remaining Parmesan cheese and breadcrumbs in a small bowl. Sprinkle over cauliflower. Reduce oven temperature to 400 °F and return cauliflower dish to oven for 20-25 minutes. For an extra crispy topping, broil casserole for 2-3 minutes under a high broil.
¼ cup Panko bread crumbs, ½ cup grated Parmesan cheese
Serve with cauliflower with fresh thyme and enjoy!

Notes
Ingredients: Freshly shredded cheese is the best option.
Size: Large pieces of cauliflower give the crunchiest bite while small pieces might overcook.
Prep-Ahead: Follow all of the instructions up to sprinkling on the topping. Cover and refrigerate, with the topping stored in a separate container. Pull it out at least 1 hour before baking to allow it to come to room temperature. Sprinkle the topping over the cauliflower and follow the remaining steps for baking it in the oven.
Storage: This cauliflower gratin tastes best when it is served immediately. You can save covered leftovers in the refrigerator for up to 3-5 days. Just note it will get soggy and not have the same incredible texture. Take it out of the fridge 30 minutes ahead of time, then bake at 350°F for 10-20 minutes.
Freezing: Freezing is not recommended as it will become very watery upon thawing.
