2. Step-by-Step Instructions for Cauliflower Gratin with Cheddar and Chives

Follow these steps to make a deliciously creamy, cheesy cauliflower gratin:

Step 1: Preheat the Oven and Prepare the Cauliflower

1. Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
2. In a large pot of salted boiling water, blanch the cauliflower florets for 3-4 minutes until slightly tender. Drain and set aside.

Step 2: Make the Cheddar Cheese Sauce

1. In a medium saucepan, melt 2 tablespoons of butter over medium heat.
2. Add the flour and whisk continuously for 1-2 minutes to make a roux. This will thicken the sauce.
3. Gradually whisk in the milk, stirring constantly to avoid lumps. Continue cooking until the sauce thickens, about 3-4 minutes.
4. Reduce the heat to low, add 1 cup of the shredded cheddar cheese, and stir until melted and smooth.
5. Season the cheese sauce with salt, black pepper, and garlic powder, if using.

Step 3: Combine Cauliflower and Cheese Sauce

1. In a large mixing bowl, combine the blanched cauliflower with the cheese sauce, stirring gently to coat the cauliflower evenly.
2. Pour the mixture into the prepared baking dish, spreading it out evenly.

Step 4: Add Toppings

1. Sprinkle the remaining cheddar cheese (1/2 cup) and chopped chives over the top of the cauliflower.
2. Melt the remaining tablespoon of butter and combine it with the breadcrumbs. Sprinkle the breadcrumb mixture evenly over the top for a crispy finish.

Step 5: Bake the Gratin

1. Bake in the preheated oven for 20-25 minutes, or until the top is golden and bubbling.
2. Let the gratin cool for a few minutes before serving.

3. Tips for Perfect Cauliflower Gratin with Cheddar and Chives

3.1 Blanch Cauliflower Lightly

Blanch the cauliflower briefly to soften slightly while keeping it firm. This prevents the gratin from becoming watery during baking.

3.2 Use Sharp Cheddar Cheese

Sharp cheddar adds a rich, tangy flavor to the sauce, balancing the mildness of the cauliflower.

3.3 Add Breadcrumbs for Crunch

Breadcrumbs create a golden, crispy top layer, adding texture to the creamy gratin.

3.4 Garnish with Extra Chives for Freshness

Sprinkle a few fresh chives on top after baking for a burst of color and a fresh finish.
