Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 1 pound Yukon gold potatoes – sliced into ½-inch rounds

• 1 medium head cauliflower – cut into florets, about 5 to 6 cups

• 4 tablespoons unsalted butter

• ¼ cup all-purpose flour

• 1.5 cups milk – any fat content

• ½ cup low-sodium vegetable broth

• 1 tablespoon Dijon mustard

• 1 teaspoon onion powder

• 1 teaspoon garlic powder

• ¼ teaspoon salt

• ¼ teaspoon freshly ground black pepper

• ¼ cup shredded Parmesan cheese

• 1.25 cups shredded sharp cheddar cheese – divided

• ¼ cup chopped fresh chives

Directions

1. Preheat the oven to 375°F (190°C). Grease a 9×13-inch rectangular baking dish and set aside.

2. In a large pot, place the sliced potatoes and cover them with salted water. Make sure the potatoes are submerged by at least a couple of inches, as there will also be cauliflower. Bring the pot to a boil, then add the cauliflower florets. Cook for 8 to 10 minutes, until the potatoes are tender but not falling apart. Drain the vegetables.

3. While the veggies are cooking, melt the butter in a saucepan over medium heat. Whisk in the flour to form a paste. Slowly pour in the milk, followed by the vegetable broth, whisking constantly. Cook for a few more minutes, whisking often, until the sauce thickens.

4. Stir in the Dijon mustard, onion powder, garlic powder, salt, and pepper. Remove from heat and stir in the Parmesan cheese and ¾ cup of cheddar cheese until the cheese is melted and the sauce is smooth.

5. Transfer the cooked potatoes and cauliflower to the greased baking dish, spreading them out in an even layer. Pour the cheese sauce over the vegetables, making sure to cover them evenly.

6. Sprinkle the casserole with the remaining cheddar cheese and chopped chives. If you prefer, use kitchen shears to quickly cut the chives over the casserole.

7. Bake for 20 to 25 minutes, until the sauce is bubbling and the cheese is slightly browned. Turn on the broiler and finish baking for an additional 2 to 3 minutes to achieve a fully browned top.

8. Remove from the oven and garnish with extra fresh chives if desired. Let the dish sit for 5 to 10 minutes before serving.
