What Ingredients You Will Need

This recipe uses wholesome, straightforward ingredients to deliver a cheesy, comforting dish that’s perfect for sharing. You’ll love how easy it is to put together with minimal fuss!

For the Vegetables:

• 2 cups broccoli florets (fresh or frozen)
• 2 cups cauliflower florets (fresh or frozen)
• 1 tablespoon olive oil
• Salt and black pepper (to taste)

For the Creamy Cheddar Sauce:

• 2 tablespoons unsalted butter
• 2 cloves garlic, minced
• 2 tablespoons all-purpose flour
• 1 ½ cups milk (whole milk works best for creaminess)
• 1 cup sharp cheddar cheese, shredded
• ½ cup Parmesan cheese, grated
• ½ teaspoon ground mustard (adds depth to the cheese flavor)
• Pinch of paprika (optional, for a gentle kick)

For the Topping:

• ½ cup breadcrumbs (use panko for extra crunch)
• 2 tablespoons unsalted butter, melted
• 2 tablespoons Parmesan cheese, grated
• Chopped parsley (for garnish, optional)

Equipment Needed

• A medium-sized saucepan (for the creamy cheese sauce)
• Large pot (to blanch the vegetables)
• Baking dish (9×13-inch works well; glass or ceramic is great)
• Whisk (for a smooth, lump-free sauce)
• Mixing bowls (for combining the topping)
• Cutting board and knife (to prep the veggies)
• Oven mitts (because safety first!)

If you don’t have panko breadcrumbs, regular breadcrumbs will work just fine. And if you’re short on baking dishes, a cast-iron skillet makes an excellent substitute—it even adds a rustic charm for serving!

Preparation Method

1. Preheat your oven to 375°F (190°C). Grease your baking dish lightly with olive oil or cooking spray to prevent sticking.
2. Bring a large pot of salted water to a boil. Add the broccoli and cauliflower florets and blanch for 2-3 minutes, just until they start to soften but are still bright in color. Drain and set aside.
3. In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add minced garlic and sauté for about 1 minute, until fragrant.
4. Sprinkle in the flour and whisk constantly for 1-2 minutes to cook out the raw taste. Be careful not to let it brown too much.
5. Gradually pour in the milk while whisking to avoid lumps. Cook for about 3-5 minutes, stirring often, until the mixture thickens and coats the back of a spoon.
6. Lower the heat and stir in the shredded cheddar cheese and grated Parmesan until melted and smooth. Add ground mustard, paprika, and a pinch of salt and pepper. Taste and adjust seasoning as needed. Remove from heat.
7. Place the blanched broccoli and cauliflower into the prepared baking dish, arranging them evenly.
8. Pour the creamy cheese sauce over the vegetables, ensuring they’re fully coated.
9. In a small mixing bowl, combine the breadcrumbs, melted butter, and grated Parmesan cheese. Sprinkle this mixture evenly over the top of the gratin.
10. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbly.
11. Remove from the oven and let it cool for 5 minutes before serving. Garnish with chopped parsley if desired.

Cooking Tips & Techniques

Here are some pro tips to ensure your Creamy Cheddar Broccoli Cauliflower Gratin turns out perfectly every time:

• Don’t skip the blanching: Blanching the broccoli and cauliflower ensures they cook evenly and retain their vibrant colors. Plus, it prevents them from becoming mushy in the oven.
• Use a block of cheese: Pre-shredded cheese might seem convenient, but freshly grated cheese melts much better and gives you that luscious, creamy texture.
• Watch your sauce: Don’t walk away from the stove while making the cheese sauce. Keep stirring to prevent lumps or scorching.
• Customize the topping: Add crushed crackers or even crumbled bacon to the breadcrumb mixture for extra flavor and crunch.
• Make it ahead: You can assemble the gratin a day ahead, cover, and refrigerate it. Just bake it when you’re ready to serve!

Variations & Adaptations

This gratin is incredibly versatile, so feel free to make it your own. Here are a few ideas to get your creative juices flowing:

• Low-carb option: Swap out the all-purpose flour for almond or coconut flour in the cheese sauce.
• Vegan version: Use a plant-based milk and vegan cheese, and substitute the butter with olive oil or plant-based margarine.
• Add protein: Mix in cooked chicken or ham for a heartier main dish.
• Seasonal twist: Replace broccoli and cauliflower with zucchini and yellow squash in the summer, or sweet potatoes and parsnips in the fall.
• Spice it up: Add diced jalapeños or a pinch of cayenne pepper to the cheese sauce for a kick of heat.

Serving & Storage Suggestions

This Creamy Cheddar Broccoli Cauliflower Gratin is best served hot and fresh out of the oven. The golden crust will be at its crispiest, and the cheese sauce will be decadently melty.
