## Ingredients You’ll Need
* **Broccoli:** 1 large head, cut into florets. Fresh broccoli is best for optimal flavor and texture. Look for firm, green florets with no signs of yellowing.
* **Cauliflower:** 1 large head, cut into florets. Similar to broccoli, choose a head of cauliflower that is firm and white with tightly packed florets.
* **Butter:** 6 tablespoons, unsalted. Butter adds richness and flavor to the sauce. You can use salted butter, but reduce the amount of salt in the recipe accordingly.
* **All-Purpose Flour:** 1/4 cup. Flour is used to thicken the sauce. Make sure to cook it properly to avoid a floury taste.
* **Milk:** 3 cups, whole milk or 2%. Whole milk will result in a richer, creamier sauce, but 2% milk works just fine. You can also use a combination of milk and cream for an even more decadent sauce.
* **Heavy Cream:** 1/2 cup (optional, for extra richness). Heavy cream adds a luxurious touch to the sauce. If you’re watching your calorie intake, you can omit it or substitute with more milk.
* **Sharp Cheddar Cheese:** 2 cups, shredded. Sharp cheddar cheese provides a bold and tangy flavor that complements the vegetables perfectly. You can use a different type of cheese, such as Gruyere, Parmesan, or a combination of cheeses.
* **Gruyere Cheese:** 1 cup, shredded (optional, for a nutty flavor). Gruyere cheese adds a nutty and slightly sweet flavor to the gratin. It melts beautifully and creates a lovely golden-brown crust.
* **Parmesan Cheese:** 1/2 cup, grated (for topping). Parmesan cheese adds a salty and savory flavor to the topping. It also helps to create a crispy crust.
* **Breadcrumbs:** 1/2 cup, plain or panko. Breadcrumbs add a crunchy texture to the topping. Panko breadcrumbs are larger and coarser than plain breadcrumbs, resulting in a more noticeable crunch.
* **Garlic:** 2 cloves, minced. Garlic adds a pungent and aromatic flavor to the sauce. Adjust the amount to your preference.
* **Nutmeg:** 1/4 teaspoon, ground. Nutmeg adds a warm and subtle spice to the sauce. A little goes a long way.
* **Salt and Pepper:** To taste. Season generously with salt and pepper to enhance the flavors of the vegetables and sauce.
* **Olive Oil:** 1 tablespoon (for drizzling). Olive oil is used to drizzle over the vegetables before roasting, adding flavor and helping them to brown.
## Equipment You’ll Need
* **Large Pot:** For boiling the broccoli and cauliflower.
* **Colander:** For draining the vegetables.
* **Large Skillet or Saucepan:** For making the cheese sauce.
* **9×13 inch Baking Dish:** For assembling and baking the gratin.
* **Mixing Bowls:** For tossing the vegetables and combining the topping ingredients.
* **Whisk:** For making the cheese sauce.
* **Grater:** For grating the cheese.
## Step-by-Step Instructions
**1. Prepare the Vegetables:**
* Preheat your oven to 400°F (200°C). This ensures the vegetables roast properly and don’t steam.
* Wash the broccoli and cauliflower thoroughly. Remove any leaves and trim the stems. Cut both into bite-sized florets. Uniform sizes ensure even cooking.
* In a large pot, bring salted water to a boil. Salt helps season the vegetables from the inside out.
* Add the cauliflower florets to the boiling water and cook for 3-4 minutes. Cauliflower takes slightly longer to cook than broccoli.
* Add the broccoli florets to the pot and cook for another 2-3 minutes. The vegetables should be slightly tender-crisp. Avoid overcooking, as they will continue to cook in the oven.
* Drain the vegetables in a colander and rinse with cold water. This stops the cooking process and helps retain their vibrant color. Pat dry with paper towels to remove excess moisture. Excess moisture can lead to a soggy gratin.
* Transfer the broccoli and cauliflower to a large bowl. Drizzle with olive oil, salt, and pepper. Toss to coat evenly. This adds flavor and helps the vegetables to brown nicely during roasting.
* Spread the vegetables in a single layer on a baking sheet. Roast in the preheated oven for 15-20 minutes, or until slightly tender and lightly browned. Roasting the vegetables before assembling the gratin enhances their flavor and prevents them from becoming mushy.
**2. Make the Cheese Sauce:**
* While the vegetables are roasting, prepare the cheese sauce. This ensures everything is ready to go when the vegetables are done.
* In a large skillet or saucepan, melt the butter over medium heat. The butter should be melted completely, but not browned.
* Whisk in the flour and cook for 1-2 minutes, stirring constantly. This creates a roux, which is the base for the cheese sauce. Cooking the flour properly eliminates any floury taste.
* Gradually whisk in the milk, a little at a time, until smooth. Whisking constantly prevents lumps from forming. Use a wire whisk for best results.
* Bring the mixture to a simmer, stirring occasionally. Continue to simmer for 5-7 minutes, or until the sauce has thickened. The sauce should be thick enough to coat the back of a spoon.
* Remove from heat and stir in the shredded cheddar cheese, Gruyere cheese (if using), minced garlic, nutmeg, salt, and pepper. Stir until the cheese is melted and the sauce is smooth. Taste and adjust the seasoning as needed. Don’t be afraid to add more salt, pepper, or nutmeg to enhance the flavor.
* Stir in the heavy cream (if using) for an extra-rich sauce. The heavy cream adds a luxurious touch and makes the sauce even more decadent.
**3. Assemble the Gratin:**
* Reduce the oven temperature to 375°F (190°C). Lowering the temperature prevents the topping from burning before the gratin is heated through.
* Lightly grease a 9×13 inch baking dish. This prevents the gratin from sticking to the dish.
* Spread the roasted broccoli and cauliflower evenly in the prepared baking dish. Arrange the vegetables in a single layer for even cooking.
* Pour the cheese sauce over the vegetables, making sure to coat them evenly. Use a spatula to spread the sauce and ensure it reaches all the nooks and crannies.
* In a small bowl, combine the breadcrumbs and grated Parmesan cheese. Mix well to combine.
* Sprinkle the breadcrumb mixture evenly over the cheese sauce. The breadcrumbs will create a crispy and golden-brown topping.
**4. Bake the Gratin:**
* Bake in the preheated oven for 20-25 minutes, or until the topping is golden brown and the cheese sauce is bubbly. The gratin is ready when the topping is crispy and the cheese sauce is heated through and bubbling around the edges.
* Let the gratin cool for a few minutes before serving. This allows the cheese sauce to set slightly and prevents it from being too runny.
## Tips for the Perfect Gratin
* **Don’t Overcook the Vegetables:** The broccoli and cauliflower should be slightly tender-crisp. Overcooked vegetables will become mushy in the gratin.
* **Use Good Quality Cheese:** The cheese is the star of the show, so use the best quality you can afford. Sharp cheddar and Gruyere are excellent choices.
* **Grate Your Own Cheese:** Pre-shredded cheese often contains cellulose, which can prevent it from melting smoothly. Grating your own cheese ensures a smoother, creamier sauce.
* **Toast the Breadcrumbs:** Toasting the breadcrumbs before adding them to the topping will enhance their flavor and texture. Simply spread the breadcrumbs on a baking sheet and toast in the oven for a few minutes, until golden brown.
* **Add Some Spice:** If you like a little heat, add a pinch of red pepper flakes to the cheese sauce.
* **Make it Ahead:** You can assemble the gratin ahead of time and store it in the refrigerator for up to 24 hours. Add a few minutes to the baking time if baking from cold.
## Variations and Additions
* **Add Protein:** Cooked ham, bacon, or sausage can be added to the gratin for a heartier meal.
* **Use Different Vegetables:** Feel free to add other vegetables, such as carrots, Brussels sprouts, or asparagus.
* **Change the Cheese:** Experiment with different cheeses, such as Monterey Jack, Havarti, or Gouda.
* **Add Herbs:** Fresh herbs, such as thyme, rosemary, or parsley, can add a burst of flavor to the gratin.
* **Make it Gluten-Free:** Use gluten-free flour and breadcrumbs to make this gratin gluten-free.
## Serving Suggestions
* Serve the broccoli and cauliflower gratin as a side dish with roasted chicken, steak, or fish.

* It’s also a great addition to a holiday meal or potluck.
