Ingredients

• 2 cups cauliflower florets
• 2 cups broccoli florets
• 1 1/2 cups sliced carrots
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups whole milk (warm)
• 1 cup shredded cheddar cheese
• 1/2 cup grated Parmesan cheese
• 1/2 teaspoon garlic powder
• 1/4 teaspoon ground nutmeg
• Salt and freshly ground black pepper, to taste
• 1/4 cup breadcrumbs (optional, for topping)
• 1 tablespoon chopped parsley (for garnish)

Instructions

1. Step 1: Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
2. Step 2: Wash and chop the cauliflower, broccoli, and carrots into bite-sized pieces. Steam the vegetables for 5–7 minutes until just tender.
3. Step 3: In a saucepan over medium heat, melt the butter. Stir in the flour to create a roux and cook for 1–2 minutes, stirring constantly.
4. Step 4: Gradually whisk in the warm milk, cooking until the sauce thickens, about 3–5 minutes.
5. Step 5: Stir in garlic powder, ground nutmeg, salt, and pepper. Add the cheddar and Parmesan cheeses, stirring until melted and smooth.
6. Step 6: Place the steamed vegetables in a large bowl and pour the cheese sauce over them. Gently combine to coat evenly.
7. Step 7: Transfer the mixture to the prepared baking dish. If using, sprinkle the breadcrumbs evenly over the top.
8. Step 8: Bake for 20–25 minutes until the casserole is bubbly and golden on top. For a crispier crust, broil for 2–3 minutes, watching carefully.
9. Step 9: Let the casserole rest for 5–10 minutes before garnishing with chopped parsley. Serve warm and enjoy.

Tips & Variations

• For added flavor, mix in cooked bacon or sautéed mushrooms before baking.
• Try different cheeses like Gruyère or mozzarella for a varied taste.
• Use gluten-free flour and breadcrumbs to make this dish gluten-free.
• If you prefer softer vegetables, steam them a bit longer but avoid overcooking to keep texture.

Storage

Scale 1x2x3x

Vegetables

• 2 cups cauliflower florets
• 2 cups broccoli florets
• 1 1/2 cups sliced carrots

Cheese Sauce

• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups whole milk (warm)
• 1 cup shredded cheddar cheese
• 1/2 cup grated Parmesan cheese
• 1/2 teaspoon garlic powder
• 1/4 teaspoon ground nutmeg
• Salt and freshly ground black pepper, to taste

Topping and Garnish

• 1/4 cup breadcrumbs (optional, for topping)
• 1 tablespoon chopped parsley (for garnish)

Instructions

1. Preheat and Prepare Dish: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish to prevent sticking and set aside.
2. Steam Vegetables: Wash and cut the cauliflower, broccoli, and carrots into bite-sized pieces. Steam the vegetables for about 5 to 7 minutes until they are just tender but still retain some firmness.
3. Make Roux: In a medium saucepan over medium heat, melt the butter. Stir in the all-purpose flour and cook together for 1 to 2 minutes, forming a roux that will help thicken the sauce.
4. Add Milk to Roux: Gradually whisk in the warm whole milk to the roux to avoid lumps. Continue cooking and whisking for 3 to 5 minutes until the sauce thickens into a creamy consistency.
5. Season and Add Cheese: Stir in the garlic powder, nutmeg, salt, and black pepper to taste. Then add the shredded cheddar and grated Parmesan cheese, stirring until completely melted into the sauce.
6. Combine with Vegetables: Place the steamed vegetables in a large bowl and pour the cheese sauce over them. Gently toss everything together to evenly coat the vegetables in the creamy sauce.
7. Prepare for Baking: Transfer the vegetable and cheese mixture into the greased baking dish. Sprinkle the optional breadcrumbs evenly on top if using, which will create a crisp golden crust.
8. Bake and Broil: Bake in the preheated oven for 20 to 25 minutes until the casserole is bubbly and the top is golden. For an extra crispy topping, broil for an additional 2 to 3 minutes, watching carefully to avoid burning.
9. Rest and Serve: Remove the casserole from the oven and let it rest for 5 to 10 minutes to thicken further. Garnish with chopped fresh parsley before serving warm.

Notes

• Steaming vegetables just until tender helps retain their texture and nutrients.
• Using warm milk when making the roux-based sauce prevents lumps from forming.
• Breadcrumb topping is optional but adds a nice crunchy texture contrast.
• For a lighter version, substitute whole milk with 2% milk, though it may slightly affect creaminess.
• Leftovers can be refrigerated and gently reheated in the oven to maintain texture.
