This Easy Cauliflower Gratin with Gruyère is a creamy, cheesy delight that makes a perfect side dish for any meal. With tender cauliflower florets and a rich Gruyère sauce, this gratin is topped with a golden, crispy breadcrumb mixture for an extra layer of flavor and texture.
INGREDIENTS
- Bread: 3 slices white sandwich bread, torn into large pieces for a homemade breadcrumb topping.
- Parmesan Cheese: 2 tablespoons, grated, adds a rich flavor to the breadcrumbs.
- Butter: 3 tablespoons, used in the roux and for richness.
- Flour: ⅓ cup all-purpose, for thickening the sauce.
- Milk: 2 cups, creating the base of the creamy sauce.
- Cauliflower: 1 head (about 2 pounds), cored and cut into small florets.
- Gruyère Cheese: 4 ounces, grated, provides a rich and nutty flavor.
- Salt and Pepper: To taste, for seasoning the dish.
INSTRUCTIONS
- Step 1:
- Preheat the oven to 350°F. In a food processor, combine the bread and Parmesan cheese. Pulse until coarse crumbs form, about 3 to 4 times. Set aside the breadcrumb mixture.
- Step 2:
- In a large saucepan, melt the butter over medium heat. Add the flour and cook, whisking constantly for about 1 minute until the mixture turns slightly golden. Gradually whisk in the milk until smooth and bring to a simmer.
- Step 3:
- Add the cauliflower florets to the saucepan, season with salt and pepper, and cover with a lid. Cook for about 5 minutes, until the cauliflower starts to soften.
- Step 4:
- Remove the saucepan from heat and gradually stir in the grated Gruyère cheese until melted and combined with the sauce.
- Step 5:
- Pour the cauliflower mixture into a 2-quart baking dish. Sprinkle the prepared breadcrumb mixture evenly over the top.
- Step 6:
- Cover the baking dish with aluminum foil and bake for 20 minutes, until the cauliflower is easily pierced with a knife.
- Step 7:
- Remove the foil and bake for an additional 20 minutes, or until the breadcrumbs are golden brown. Serve hot.
Serving and Storage Tips
- Serve the cauliflower gratin warm as a side dish with roasted chicken, beef, or pork. It pairs perfectly with a fresh green salad for a balanced meal.
- Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through to retain its crispy breadcrumb topping.
- For a quick reheat, use the microwave, but note that the breadcrumb topping may lose some of its crunch.
Helpful Notes
- To save time, you can prepare the cauliflower and breadcrumb topping in advance and refrigerate them separately. Assemble just before baking.
- If you don't have Gruyère, substitute with another melty cheese like Swiss or Fontina for a similar flavor.
- The roux should be cooked just until it turns golden brown to avoid a raw flour taste in the sauce.
