For the Casserole
- Butter – Adds richness and serves as a base for sautéing; substitute with olive oil for a lighter option.
- Onion – Provides aromatic sweetness; shallots can be used for a milder flavor.
- Garlic – Minced for a fragrant undertone; you can use garlic powder (1/4 tsp) if you’re short on fresh garlic.

Step‑by‑Step Instructions for Creamy Vegetable Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This ensures the perfect baking environment for your creamy vegetable casserole. While the oven heats up, you can prepare your vegetables and sauce, making the most of your time and ensuring a seamless cooking process.
Step 2: Sauté the Aromatics
In a large skillet, melt 2 tablespoons of butter over medium heat. Once melted, add one diced onion and sauté for about 5 minutes, or until the onion becomes translucent and fragrant. The heat will bring out the natural sweetness, setting a delicious base for the creamy vegetable casserole.
Step 3: Add Garlic and Mushrooms
Next, stir in 3 minced garlic cloves and 8 ounces of sliced mushrooms. Cook for an additional 4 minutes, stirring occasionally until the mushrooms are tender and have released their moisture. You’ll notice a wonderful aroma filling your kitchen, which signals it’s time to move on to the next step!
Step 4: Incorporate the Vegetables
Add 1 cup of broccoli florets, 1 cup of cauliflower florets, 1 cup of sliced carrots, and 1 cup of frozen peas to the skillet. Cook the mixture for 5–7 minutes, stirring frequently until the vegetables are slightly softened yet still vibrant. This medley of veggies forms the heart of your creamy vegetable casserole.
Step 5: Whisk the Sauce Together
In a mixing bowl, combine 10.5 ounces of cream of mushroom soup, ½ cup of milk, and ½ cup of sour cream. Whisk until the mixture is smooth and well-blended. This creamy concoction will provide that rich flavor and a cozy texture that makes the casserole so delightful.
Step 6: Season the Sauce
Stir in 1 cup of shredded cheddar cheese, 1 teaspoon of salt, ½ teaspoon of black pepper, and 1 teaspoon of dried thyme into the sauce. Mix thoroughly until everything is well combined and the cheese starts to melt slightly. This is the moment when your creamy vegetable casserole begins to take shape!
Step 7: Combine Vegetables and Sauce
Gently fold the sautéed vegetable mixture into the creamy sauce, ensuring all the veggies are coated evenly. Take your time with this step, as you want every bite to be a perfect combination of flavors and textures.
Step 8: Transfer to Baking Dish
Grease a 9×13-inch baking dish, then pour the creamy vegetable casserole mixture into it. Spread it out evenly, making sure the top is smooth. This will allow for even cooking and a lovely golden finish when you bake it.
Step 9: Prepare the Topping
In a small bowl, mix 1 cup of bread crumbs with ¼ cup of grated Parmesan cheese. Sprinkle this crunchy topping evenly over the casserole. This will create a delightful contrast to the creamy interior while adding an enticing golden-brown crust.
Step 10: Bake to Perfection
Place the casserole in the preheated oven and bake for 25–30 minutes. You’ll know it’s ready when the top is golden brown and bubbly, with delicious aromas filling your kitchen. The perfect indicator of doneness is the bubbling edges of the casserole!
Step 11: Rest Before Serving
Once out of the oven, let the creamy vegetable casserole cool for 10 minutes before serving. This resting time allows the sauce to set, making it easier to serve and enjoy. Get ready to dig into that warm, comforting dish that you’ve just created!

Creamy Vegetable Casserole Recipe FAQs
How do I choose the right vegetables for this casserole?
Absolutely! When selecting fresh vegetables, look for vibrant colors and firmness. Aim for broccoli florets and cauliflower that are bright and without dark spots. Freshness is key, so whether you choose seasonal veggies or frozen options, make sure they are within their best use dates.
How should I store leftover creamy vegetable casserole?
Very! Once your casserole has cooled completely, store it in an airtight container in the fridge for up to 3-4 days. When reheating, you can either pop individual servings in the microwave or rewarm the entire casserole in the oven at 350°F (175°C) for about 20 minutes, until heated through and bubbly.
Can I freeze creamy vegetable casserole?
Absolutely! To freeze, let the casserole cool completely, then transfer it to a freezer-safe container. It will keep well for up to 3 months. For reheating, thaw it overnight in the fridge, then bake at 350°F (175°C) for about 25-30 minutes until thoroughly warm. This makes for a quick and delightful meal any busy night!
What if my casserole turns out too watery?
Very common! If your casserole is too watery, ensure that you’ve sautéed your vegetables until just tender, as excess moisture can be released during cooking. Additionally, a quick fix is to sprinkle some extra bread crumbs on top during the last 10 minutes of baking to help absorb some of that liquid, creating a thicker texture.
Are there any dietary concerns for this recipe?
Certainly! This creamy vegetable casserole can be made accommodating for various dietary needs. If you’re making it for someone with dairy allergies, substitute regular milk with almond or coconut milk, and use a dairy-free cream alternative. For a healthier option, consider using Greek yogurt instead of sour cream, and avoid bread crumbs for a gluten-free version by omitting or using gluten-free options.
How do I reheat my creamy vegetable casserole without losing its texture?
To maintain the casserole’s delightful texture while reheating, preheat your oven to 350°F (175°C). Cover the dish loosely with aluminum foil to prevent it from drying out, and heat for about 20-25 minutes. This method ensures the inside stays creamy, while preventing the topping from getting too brown!
