Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This will allow the casserole to cook evenly and achieve that perfect golden crust on top.
Step 2: Prepare the Vegetables
If you’re using fresh vegetables, give them a quick rinse and chop them into bite-sized pieces. If you’re using frozen vegetables (which is perfectly fine), simply measure out the necessary amount and thaw them in the microwave or under cold running water. Once the veggies are ready, you can blanch them slightly if desired by placing them in boiling water for a couple of minutes, but this is optional since they’ll cook further in the casserole.
In a large pot, bring some water to a boil and cook the broccoli, carrots, cauliflower, and zucchini for about 3-4 minutes. You want them to be tender but still firm enough to hold their shape while baking. Drain them well to remove any excess water.
Step 3: Make the Creamy Sauce
While your veggies are draining, it’s time to prepare the creamy sauce. In a medium mixing bowl, combine the cream of mushroom soup, sour cream, cheddar cheese, milk, garlic powder, and onion powder. Stir until the mixture is smooth and creamy, and season with salt and pepper to taste.
You can add a bit more cheese for a cheesier casserole or experiment with different cheeses like Swiss or Gruyère for a more sophisticated flavor. If you prefer a lighter version, you can swap the sour cream for Greek yogurt, which will give it a tangy note while keeping it creamy.
Step 4: Mix the Vegetables and Sauce
In a large mixing bowl, combine your cooked vegetables with the creamy sauce. Stir gently to coat all the vegetables with the sauce. The goal is to have a thick, creamy mixture that will bind the vegetables together while baking.
Step 5: Transfer to a Baking Dish
Transfer the vegetable mixture into a greased 9×13-inch baking dish (or any oven-safe dish of similar size). Use a spatula to spread the mixture evenly, ensuring that the vegetables are well-distributed.
Step 6: Add the Topping
In a small bowl, mix the panko breadcrumbs with the melted butter and parmesan cheese (if using). Sprinkle the breadcrumb mixture evenly over the top of the casserole. This will give the dish a lovely crunchy, golden-brown topping once baked.
Step 7: Bake
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the casserole is bubbly around the edges. The cheese should be melted, and the breadcrumb topping should be perfectly crisp.
Step 8: Serve and Enjoy
Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. Garnish with some fresh herbs like parsley or dill if desired. Serve hot, and enjoy the hearty, cheesy goodness of your vegetable casserole!
Tips for the Best Hearty Vegetable Casserole
- Mix Up the Veggies: This casserole is highly customizable, so feel free to swap out any of the vegetables based on what you have available or your personal preferences. Consider adding sweet potatoes, green beans, or corn for extra variety.
- Make It Vegan: To make a vegan version, use non-dairy milk (such as almond or oat milk), vegan cheese, and vegan sour cream or cashew cream in place of the dairy ingredients. Use vegetable broth instead of the cream of mushroom soup or make your own from scratch.
- Add Protein: While this casserole is great as a side dish, you can make it a complete meal by adding some chopped cooked chicken, ground turkey, or even beans like chickpeas or black beans for extra protein.
- Prep Ahead: This casserole can be made in advance! Prepare the casserole up to the point of baking, cover it with foil, and refrigerate it overnight. When ready to bake, simply remove it from the fridge and bake as directed, adding an extra 5-10 minutes to the cooking time to ensure it’s heated through.
- Leftovers: This casserole stores beautifully in the fridge for 3-4 days. Reheat individual servings in the microwave or in a hot oven until warmed through. It also freezes well for up to 2-3 months, so feel free to make a double batch and save some for later.
