Ingredients You’ll Need for Vegetable Casserole

The beauty of vegetable casseroles is how easily you can customize the ingredients. Here’s a basic list for a delicious, healthy casserole with a medley of vegetables:

For the Casserole:

  • 1 cup carrots, sliced
  • 1 cup cauliflower florets
  • 1 cup broccoli florets
  • 1 cup green beans, trimmed
  • 1/2 cup cooked rice (optional for a heartier dish)
  • 1 can cream of mushroom soup (or use a healthier alternative like a homemade sauce)
  • 1/4 cup milk
  • 1 1/2 cups shredded cheddar cheese (or use a dairy-free cheese for a vegan version)
  • 1/2 cup breadcrumbs (for topping)
  • 2 tablespoons butter, melted
  • Salt and pepper, to taste

For the Topping (optional):

  • 1/4 cup Parmesan cheese
  • 1/4 cup chopped fresh parsley (for garnish)
  • Chopped onions or shallots (optional for extra flavor)

This vegetable cheese casserole can be made lighter by using less cheese, or you can add some seasoned croutons for a crunchy topping.

How to Make Vegetable Casserole

Creating a delicious vegetable casserole is easy and doesn’t take much time. Follow these simple steps to make your healthy vegetable casserole:

Step 1: Preheat the Oven and Prepare the Baking Dish

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or casserole dish to prevent the vegetables from sticking.

Step 2: Prepare the Vegetables

Steam or blanch the carrots, cauliflower, broccoli, and green beans until just tender. Be careful not to overcook them, as they will continue to cook in the casserole.

If you’re using cooked rice, mix it in with the vegetables at this stage for a heartier dish.

Step 3: Make the Casserole Base

In a separate bowl, whisk together the cream of mushroom soup and milk. Add a pinch of salt and pepper to season. You can also add some garlic powder or onion powder for extra flavor.

Step 4: Combine the Vegetables and Sauce

Add the steamed vegetables to the casserole dish. Pour the soup mixture over the vegetables and stir to coat them evenly. Sprinkle 1 1/2 cups shredded cheddar cheese over the top.

Step 5: Add the Topping

In a small bowl, mix the breadcrumbs with the melted butter. Sprinkle the breadcrumb mixture over the cheese. For an extra cheesy finish, sprinkle some Parmesan cheese on top.

Step 6: Bake the Casserole

Bake in the preheated oven for 25-30 minutes or until the casserole is bubbly and golden brown on top. If you want a crispier topping, broil for 2-3 minutes at the end of the baking time.

Step 7: Serve and Enjoy

Once the casserole is done, remove it from the oven and let it cool for 5 minutes before serving. Garnish with fresh parsley or additional grated cheese if desired.

Customizing Your Vegetable Casserole

Here are a few tips for customizing this vegetable casserole to suit your taste or dietary preferences:

1. Add Protein

For a more filling meal, consider adding grilled chicken, tofu, or ground turkey to the casserole. You can also use lentils or chickpeas for a plant-based protein boost.

2. Make It Gluten-Free

To make this casserole gluten-free, simply swap out the breadcrumbs for a gluten-free breadcrumb or use almond meal as a substitute. You can also use a gluten-free cream soup or make a homemade sauce with vegetable broth and cream.

3. Go Dairy-Free

If you’re following a dairy-free diet, replace the cheddar cheese with a dairy-free cheese alternative. You can also make the casserole with non-dairy milk (such as almond or coconut milk) and skip the cheese entirely for a lighter option.

4. Spice It Up

Add a bit of heat to your casserole by mixing in chopped jalapeños, a pinch of cayenne pepper, or a sprinkle of chili flakes. This adds a nice kick to the dish and pairs well with the richness of the cheese.

5. Use Different Vegetables

Feel free to swap out the vegetables based on what you have on hand. You can add spinach, kale, peas, or even sweet potatoes for a different twist. Seasonal vegetables like winter squash also make a great addition.

How to Serve Vegetable Casserole

This casserole with carrots and mixed vegetables is a versatile dish that can be served alongside many main courses. Here are some serving suggestions:

1. With Grilled Meats

Serve this vegetable casserole with grilled chicken, steak, or roast pork for a hearty meal. The casserole pairs well with both light and heavier meats.

2. With Roasted Vegetables

For a completely vegetable-focused meal, serve this casserole with a side of roasted vegetables like brussels sprouts, sweet potatoes, or asparagus.

3. As a Vegetarian Meal

For a vegetarian dinner, this casserole works perfectly as a standalone dish. You can even serve it with a side of whole grain bread or garlic bread for added texture and flavor.

4. With Rice or Quinoa

Pair this vegetable casserole with rice or quinoa for a grain-based side that complements the creamy casserole.

Storing and Reheating Vegetable Casserole

Leftovers of this vegetable cheese casserole can be stored in an airtight container in the fridge for up to 4 days. To reheat, simply microwave individual servings or place the casserole back in the oven at 350°F (175°C) for 15-20 minutes until heated through.

For longer storage, you can freeze this casserole for up to 3 months. Just make sure it’s properly cooled and wrapped before placing it in the freezer.
