Plus, it’s incredibly easy to prepare, making it ideal for busy weeknights or potlucks. Trust me, once you try this recipe, it will become a regular on your dinner table!

Ingredients:

• For the Vegetables:
• 1 large head of broccoli, cut into florets
• 1 large head of cauliflower, cut into florets
• 1 tablespoon olive oil
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• For the Cheese Sauce:
• 6 tablespoons unsalted butter
• 6 tablespoons all-purpose flour
• 3 cups milk (whole milk recommended for richness)
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon ground nutmeg
• 1/4 teaspoon garlic powder
• 1/4 teaspoon onion powder
• 4 cups shredded cheddar cheese (sharp or medium, your preference!)
• 1 cup shredded Gruyere cheese (optional, but adds a lovely nutty flavor)
• For the Topping:
• 1 cup panko breadcrumbs
• 4 tablespoons unsalted butter, melted
• 1/4 cup grated Parmesan cheese
• 1/4 teaspoon paprika

Preparing the Vegetables

1. Preheat your oven to 400°F (200°C). This ensures the vegetables roast evenly.
2. Prepare the broccoli and cauliflower. Wash the broccoli and cauliflower thoroughly. Cut them into florets, ensuring they are roughly the same size for even cooking.
3. Toss with olive oil and seasoning. In a large bowl, toss the broccoli and cauliflower florets with the olive oil, salt, and pepper. Make sure the vegetables are evenly coated. This helps them roast properly and develop a nice flavor.
4. Roast the vegetables. Spread the seasoned broccoli and cauliflower in a single layer on a large baking sheet. Roast for 20-25 minutes, or until the vegetables are tender-crisp and lightly browned. Keep an eye on them to prevent burning. You want them to be cooked through but still have a little bite.

Making the Cheese Sauce

1. Melt the butter. In a large saucepan over medium heat, melt the butter completely. Make sure it doesn’t brown.
2. Whisk in the flour. Add the flour to the melted butter and whisk constantly for 1-2 minutes to create a roux. This will thicken the sauce. The roux should be smooth and pale golden in color.
3. Gradually add the milk. Slowly pour in the milk, whisking continuously to prevent lumps from forming. Continue whisking until the sauce is smooth and starts to thicken. This process might take a few minutes, so be patient.
4. Simmer and thicken. Reduce the heat to low and simmer the sauce for 5-7 minutes, stirring occasionally, until it thickens to a coating consistency. It should be thick enough to coat the back of a spoon.
5. Season the sauce. Stir in the salt, pepper, nutmeg, garlic powder, and onion powder. Taste and adjust seasonings as needed. This is where you can customize the flavor to your liking.
6. Add the cheese. Remove the saucepan from the heat and stir in the cheddar cheese and Gruyere cheese (if using) until the cheese is completely melted and the sauce is smooth and creamy. Make sure there are no lumps of unmelted cheese.

Assembling the Casserole

1. Combine vegetables and cheese sauce. In a large bowl, gently fold the roasted broccoli and cauliflower into the cheese sauce, ensuring the vegetables are evenly coated.
2. Pour into a baking dish. Pour the mixture into a greased 9×13 inch baking dish. You can use cooking spray or butter to grease the dish.

Preparing the Topping

1. Combine topping ingredients. In a small bowl, combine the panko breadcrumbs, melted butter, Parmesan cheese, and paprika. Mix well until the breadcrumbs are evenly coated with butter and cheese.
2. Sprinkle topping over casserole. Sprinkle the breadcrumb mixture evenly over the top of the casserole. This will create a golden-brown and crispy crust.

Baking the Casserole

1. Bake the casserole. Bake in the preheated oven for 20-25 minutes, or until the topping is golden brown and the casserole is bubbly.
2. Let it rest. Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the sauce to set slightly and prevents it from being too runny.
3. Serve and enjoy! Serve hot and enjoy this comforting and delicious Broccoli Cauliflower Casserole. It’s perfect as a side dish or even a vegetarian main course.

Tips and Variations:

• Add protein: For a heartier casserole, consider adding cooked chicken, ham, or bacon.
• Spice it up: Add a pinch of red pepper flakes to the cheese sauce for a little heat.
• Different cheeses: Experiment with different types of cheese, such as Monterey Jack, Pepper Jack, or Gouda.
• Vegetable variations: Add other vegetables like carrots, mushrooms, or bell peppers.
• Make it ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add a few extra minutes to the baking time if baking from cold.
• Gluten-free option: Use gluten-free all-purpose flour and gluten-free breadcrumbs to make this casserole gluten-free.
• Creamier sauce: For an even creamier sauce, substitute half-and-half or heavy cream for some of the milk.
• Garlic lovers: Add a clove or two of minced garlic to the butter when making the roux for extra garlic flavor.
• Herb it up: Add fresh herbs like thyme or rosemary to the cheese sauce for a more complex flavor profile.

Storage Instructions:

• Refrigerating: Store leftover Broccoli Cauliflower Casserole in an airtight container in the refrigerator for up to 3-4 days.
• Reheating: Reheat in the oven at 350°F (175°C) until heated through, or microwave individual portions.
• Freezing: While not ideal, you can freeze the casserole. Be aware that the texture of the cheese sauce may change slightly upon thawing. Wrap tightly in plastic wrap and then foil, and freeze for up to 2 months. Thaw completely in the refrigerator before reheating.
