Ingredients Breakdown

Essentials

• Cauliflower: A medium head, cut into bite-sized florets. Fresh offers the best texture here, but frozen works in a pinch.
• Butter: Creates the base for a luscious roux. Don’t skimp on this, trust me.
• Flour: Helps thicken the sauce to that perfect creamy consistency.
• Milk: Use whole milk for the richest flavor, or go half milk, half cream for extra decadence.
• Cheese: Gruyère and Parmesan are the stars here. Gruyère melts beautifully, while Parmesan adds that salty, nutty kick.
• Bread Crumbs: For a satisfying crunchy topping. Panko or homemade crumbs work wonders.

Pro Tips

• If Gruyère isn’t available, Swiss cheese makes a great substitute.
• Add a pinch of nutmeg to the sauce—it highlights the creaminess beautifully!
• Got a gluten-free eater? Swap the flour for a 1:1 gluten-free blend and the breadcrumbs for gluten-free panko.

Step-by-Step Instructions

1. Prep the Cauliflower: Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Blanch the cauliflower florets for 3-4 minutes until just tender. Drain and set aside.
2. Make the Sauce: In a medium saucepan, melt the butter over medium heat. Add the flour and whisk for 1-2 minutes to cook out the raw flavor. Gradually whisk in the milk, stirring constantly, until smooth and slightly thickened.
3. Add the Cheese: Remove the sauce from heat and stir in the grated Gruyère and half of the Parmesan. Add a pinch of salt, pepper, and nutmeg, if using. Stir until the cheese is melted and the sauce is silky.
4. Assemble: Arrange the cauliflower florets in a greased baking dish. Pour the cheese sauce evenly over the top, ensuring all the florets are coated.
5. Add the Topping: Sprinkle the remaining Parmesan and breadcrumbs over the gratin. For extra flavor, drizzle a bit of melted butter on top.
6. Bake: Pop it in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbling.
7. Serve: Let the gratin rest for 5 minutes before serving—if you can resist diving straight in!

Chef’s Tips and Tricks

• For the ultimate crisp topping, combine the breadcrumbs with a little olive oil or melted butter before sprinkling them on.
• Don’t overcook the cauliflower during the blanching step—you want it to hold its shape once baked in the creamy sauce.

Recipe Variations and Serving Suggestions

• Add Protein: Stir in cooked, diced chicken or crispy pancetta for a heartier dish.
• Mix Up the Veggies: Broccoli or thinly sliced potatoes make great additions or swaps for the cauliflower.
• Serving Ideas: Serve alongside roast chicken or steak for a classic pairing, or enjoy a lighter meal with a fresh, lemony green salad.

FAQs

• Can I make this ahead of time? Yes! Assemble the gratin without baking, cover, and refrigerate for up to 24 hours. Bake just before serving.
• How do I store leftovers? Store in an airtight container in the fridge for up to 3 days. Reheat in the oven to maintain the crisp topping.
• Can I freeze this? It’s best fresh, but you can freeze it after baking. Reheat, covered, in the oven until heated through.
