Mastering Cauliflower Au Gratin Recipe: How-To

Step 1: Prepare the Cauliflower

Begin by washing the head of cauliflower thoroughly. Remove the leaves and stem, then cut it into bite-sized florets. You want them to be small enough to cook evenly but large enough to hold their shape.

Step 2: Blanch the Cauliflower

Bring a large pot of salted water to a boil. Add the cauliflower florets and blanch them for about 3-4 minutes until just tender. Drain the florets and set them aside.

Step 3: Make the Mornay Sauce

In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add 2 tablespoons of flour and whisk constantly for about 2 minutes to create a roux. Gradually pour in 2 cups of milk, whisking continuously to avoid lumps. Cook until the mixture thickens, about 5-7 minutes. Remove from heat and stir in 1 cup of grated cheese until melted. Season with salt and pepper to taste.

Step 4: Combine and Assemble

In a large mixing bowl, combine the blanched cauliflower with the Mornay sauce. Gently fold them together until the florets are well coated. Transfer the mixture to an oven-safe baking dish.

Step 5: Add the Breadcrumb Topping

In a small bowl, mix the breadcrumbs with a tablespoon of melted butter. Sprinkle the breadcrumb mixture evenly over the cauliflower and sauce.

Step 6: Bake

Preheat your oven to 375°F (190°C). Bake the gratin for about 25-30 minutes, or until the top is golden brown and the sauce is bubbling.

Step 7: Serve and Enjoy

Once out of the oven, let the dish sit for a few minutes before serving. Enjoy this creamy, cheesy Cauliflower Au Gratin as a side dish or a main course!

If You’re Out Of…

Cauliflower: Broccoli can be a great substitute, offering a similar texture and flavor profile.
Mornay sauce ingredients: If you’re missing Gruyère, try using mozzarella or a blend of any cheese you have on hand.
Breadcrumbs: Crushed crackers or cornflakes can work as a crunchy topping if you run out.
Milk: Unsweetened almond milk or oat milk can be used in the Mornay sauce if you’re looking for a dairy-free alternative.

Troubles You Can Avoid

Don’t overcook the cauliflower during blanching, or it will become mushy in the oven.
Make sure to whisk the Mornay sauce continuously to prevent lumps from forming.
Allow the dish to cool slightly before serving to help set the sauce and make serving easier.

Keep It Fresh: Storage Guide

If you find yourself with leftovers (which is unlikely, but just in case!), store them in an airtight container in the refrigerator. They should keep for about 3-4 days. To reheat, pop them back in the oven at 350°F (175°C) for about 15-20 minutes until heated through. Alternatively, you can microwave individual portions if you’re in a hurry.

Common Qs About Cauliflower Au Gratin Recipe

Can I make Cauliflower Au Gratin ahead of time?

Absolutely! You can prepare the dish up to the baking step and store it in the refrigerator. Just bake it when you’re ready to serve. You may need to add a few extra minutes to the baking time if it’s coming straight from the fridge.

Can I freeze Cauliflower Au Gratin?

Yes, you can freeze it! Just make sure to let it cool completely before transferring it to an airtight container. It will keep well for up to 2 months. Reheat directly from the freezer, allowing extra baking time.

What cheese is best for Mornay sauce?

While Gruyère is traditional, feel free to experiment! Cheddar, mozzarella, or a mix of your favorites can be used to create a Mornay sauce that suits your taste.

Is there a way to make this dish lighter?

Yes! You can reduce the amount of cheese in the Mornay sauce or use low-fat milk and cheese alternatives. You could also skip the breadcrumb topping for a lighter version.
