Ingredients

For the Broccoli and Cauliflower Gratin:

• 2 cups broccoli florets
• 2 cups cauliflower florets
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups whole milk (or half-and-half for a richer sauce)
• 1 cup shredded sharp cheddar cheese
• 1 cup shredded Gruyère or Swiss cheese
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon salt (adjust to taste)

• ¼ teaspoon ground nutmeg (optional, for extra flavor)
• ½ cup breadcrumbs (preferably panko for extra crunch)
• 1 tablespoon fresh parsley, chopped (optional, for garnish)

Special Equipment

While making Broccoli and Cauliflower Gratin doesn’t require specialized tools, there are a few key items that will make the cooking process smoother and ensure the best results:

1. Large Pot: You’ll need a large pot to blanch the broccoli and cauliflower. This ensures the vegetables are tender without becoming too soft.
2. Medium Saucepan: A medium saucepan is necessary for preparing the creamy cheese sauce. The sauce will be used to coat the vegetables and create that luscious, velvety texture that defines the gratin.
3. Baking Dish: A medium-sized baking dish (around 8×8 or 9×9 inches) works best for this recipe. The gratin needs enough space to spread out and bake evenly.
4. Whisk: A whisk is essential for creating a smooth sauce when combining the butter, flour, and milk. It ensures that no lumps form in the sauce.
5. Shredded Cheese: Using freshly shredded cheese (rather than pre-shredded) ensures a creamier and more melty texture in the sauce. A box grater or food processor will work well for this.

Step-by-Step Instructions

1. Blanch the Broccoli and Cauliflower

Start by preparing the vegetables. Bring a large pot of water to a boil, and add a pinch of salt. Once the water is boiling, add the broccoli and cauliflower florets. Blanch them for 2-3 minutes, just until they are bright green and slightly tender. The vegetables should still have a bit of crunch, as they will continue to cook in the oven.

Once blanched, drain the vegetables well and set them aside to cool slightly. You can also run them under cold water to stop the cooking process and keep the vibrant green color intact.

2. Prepare the Cheese Sauce

In a medium saucepan, melt the butter over medium heat. Once the butter is melted, whisk in the flour to form a roux. Continue to cook the mixture for 1-2 minutes to eliminate the raw flour taste, stirring constantly.

Slowly add the milk to the roux, whisking constantly to create a smooth sauce. Bring the mixture to a gentle simmer, and cook for 3-5 minutes, or until it thickens to the consistency of heavy cream. Be sure to stir frequently to avoid any lumps.

Once the sauce has thickened, stir in the shredded cheddar and Gruyère cheeses. Continue to stir until the cheese has completely melted and the sauce is smooth and creamy. Season the sauce with garlic powder, onion powder, salt, black pepper, and nutmeg (if using). Taste the sauce and adjust the seasoning to your liking.

3. Assemble the Gratin

Preheat your oven to 375°F (190°C).

In a lightly greased 8×8-inch (or similarly sized) baking dish, arrange the blanched broccoli and cauliflower florets in an even layer. Pour the cheese sauce over the vegetables, ensuring they are evenly coated.

4. Top with Breadcrumbs

In a small bowl, combine the breadcrumbs with a tablespoon of melted butter. This will give the topping a rich, golden color and extra crunch. Sprinkle the buttered breadcrumbs evenly over the top of the gratin.

5. Bake the Gratin

Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and crispy. The cheese sauce should be bubbling around the edges. If you want an extra crispy topping, you can broil the gratin for an additional 2-3 minutes at the end of the baking time.

6. Garnish and Serve

Remove the gratin from the oven and let it cool for a few minutes before serving. Garnish with freshly chopped parsley for a pop of color and a hint of freshness.

Tips for Perfect Broccoli and Cauliflower Gratin

• Don’t Overcook the Vegetables: Blanch the broccoli and cauliflower only until they are slightly tender. Overcooking them during the blanching process can make them mushy when baked. The vegetables should still have a bite to them.
• Use Freshly Grated Cheese: Pre-shredded cheese contains anti-caking agents that can affect the creaminess of your cheese sauce. For the best texture, always grate your cheese fresh from the block.
• Add Some Spice: If you enjoy a little kick in your food, consider adding a pinch of cayenne pepper or a few dashes of hot sauce to the cheese sauce for an extra layer of flavor.
• Make It Ahead: This gratin can be prepared ahead of time. Assemble the gratin up to the point of baking, then cover it tightly and refrigerate for up to 24 hours. When you’re ready to bake, simply add a few extra minutes to the cooking time, as the dish will be cold from the fridge.
• Customize with Other Cheeses: If you’re not a fan of Gruyère, feel free to substitute it with other cheeses like Parmesan, mozzarella, or even fontina for different flavor profiles. A mix of cheeses will create a more complex and delicious gratin.

Variations of Broccoli and Cauliflower Gratin

• Broccoli Gratin Only: If you prefer just one vegetable, this recipe works wonderfully with broccoli alone. Simply double the amount of broccoli florets and skip the cauliflower for a more broccoli-centric dish.
• Cauliflower Gratin Only: Similarly, if you love cauliflower, use only cauliflower florets in this recipe. The creamy cheese sauce and crispy topping pair beautifully with cauliflower’s mild, nutty flavor.
• Bacon Broccoli and Cauliflower Gratin: For an extra savory touch, add cooked, crumbled bacon to the gratin before baking. The smoky flavor of bacon complements the creamy sauce and adds a delightful crunch.
• Vegan Broccoli and Cauliflower Gratin: For a dairy-free version, use plant-based cheese alternatives, such as cashew cheese or vegan cheddar. You can also substitute the butter and milk with non-dairy options like olive oil and almond milk.
• Spicy Broccoli and Cauliflower Gratin: Add chopped jalapeños or a sprinkle of red pepper flakes to the cheese sauce for some heat. This variation adds a spicy kick that contrasts nicely with the richness of the cheese.

Storage and Shelf Life

Broccoli and Cauliflower Gratin is best enjoyed fresh, but it can be stored in the refrigerator for up to 3 days. Let the gratin cool completely before transferring it to an airtight container. When reheating, cover the gratin with foil and bake at 350°F (175°C) for 15-20 minutes until heated through. For a crispier top, uncover the foil during the last 5 minutes of baking.

This dish does not freeze well due to the creaminess of the sauce, which can change in texture when frozen and thawed. For the best results, enjoy it within a few days of preparing it.

Side Dishes and Pairings for Broccoli and Cauliflower Gratin

To complement your Broccoli and Cauliflower Gratin, consider pairing it with the following dishes:

• Roast Chicken: The rich, savory flavors of roast chicken pair beautifully with the creamy gratin. The crispy skin and tender meat will balance out the richness of the gratin.
• Grilled Steak: A juicy grilled steak is the perfect accompaniment to the cheesy gratin. The two dishes together create a hearty and satisfying meal.
• Garlic Bread: Serve with a side of buttery garlic bread to soak up the creamy cheese sauce from the gratin. The crispy, garlicky bread is an excellent pairing with the rich flavors.
• Mixed Greens Salad: A light salad with a tangy vinaigrette can provide a refreshing contrast to the heaviness of the gratin. Try a simple mix of arugula, spinach, and fresh herbs.
• Roasted Vegetables: Serve the gratin alongside other roasted vegetables like carrots, Brussels sprouts, or sweet potatoes to create a well-rounded meal that’s full of flavor.
