I love how this casserole brings together a variety of colorful vegetables in one comforting dish. The creamy sauce coats every piece perfectly, while the cheddar cheese and breadcrumbs create a deliciously crispy topping. I also appreciate how simple and straightforward the preparation is, making it perfect for both weeknight dinners and special family meals. It is filling, flavorful, and a wonderful way for me to serve a nourishing vegetable-packed dish that everyone enjoys.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

– 2 cups broccoli florets
– 2 cups cauliflower florets
– 1 cup carrots, sliced
– 1 cup green beans, trimmed and cut into pieces
– 1 cup corn (fresh or frozen)
– 1 cup diced potatoes
– 1 cup heavy cream
– 1 cup vegetable broth
– 1 cup shredded cheddar cheese
– 1 cup breadcrumbs
– 2 tablespoons olive oil
– 1 teaspoon garlic powder
– 1 teaspoon onion powder
– 1 teaspoon dried thyme
– Salt and pepper to taste
– Fresh parsley for garnish (optional)

Directions

I start by preheating my oven to 375°F (190°C) so the casserole bakes evenly.

In a large bowl, I combine the broccoli, cauliflower, carrots, green beans, corn, and diced potatoes. I toss everything together to distribute the vegetables evenly.

In a separate bowl, I whisk together the heavy cream, vegetable broth, garlic powder, onion powder, dried thyme, salt, and pepper until the mixture is smooth and well blended.

I pour the creamy sauce over the mixed vegetables and gently stir to ensure every piece is coated.

Next, I grease a 9×13-inch baking dish with olive oil. I transfer the vegetable mixture into the dish and spread it out evenly.

I sprinkle the shredded cheddar cheese evenly over the top, then add a layer of breadcrumbs to create a crunchy, golden crust.

I bake the casserole in the preheated oven for 30–35 minutes, until the vegetables are tender and the top turns beautifully golden brown.

Once baked, I remove the dish from the oven and let it cool for about 5–10 minutes. This helps the sauce thicken slightly before serving.

If I want a fresh finish, I sprinkle chopped fresh parsley over the top just before serving.

Variations

I sometimes swap the cheddar cheese for mozzarella or Gruyère when I want a slightly different flavor profile. For added protein, I occasionally mix in cooked chicken or turkey. If I want a lighter version, I use half-and-half instead of heavy cream. I also like experimenting with seasonal vegetables such as Brussels sprouts or butternut squash for a winter twist. For a crispier topping, I mix the breadcrumbs with a little melted butter before sprinkling them on top.

Storage/Reheating

I store any leftovers in an airtight container in the refrigerator for up to 3–4 days. When I reheat, I prefer using the oven at 350°F (175°C) until warmed through to maintain the crispy topping. If I am short on time, I use the microwave, though the topping will be softer. I sometimes cover the dish with foil while reheating in the oven to prevent excessive browning.

FAQs

I can use frozen vegetables if that is what I have on hand. I make sure to thaw and drain them well to avoid excess moisture in the casserole.

I can freeze it before or after baking. I wrap it tightly and store it for up to 2 months. I thaw it in the refrigerator before reheating or baking.

What can I serve with this casserole?

I like serving it alongside roasted meats, grilled chicken, or even as a standalone vegetarian main dish.

How can I make the topping extra crispy?

I mix the breadcrumbs with a little olive oil or melted butter before sprinkling them on top to achieve a crunchier finish.
