Ingredients
List of Main Ingredients
- 2 cups cauliflower florets
- 1 cup broccoli florets
- 1 cup Brussels sprouts, halved
- 1 medium sweet potato, peeled and diced into 1-inch pieces
- 1 cup carrots, sliced into rounds
- 1 cup frozen peas
In this casserole, I use a mix of vibrant winter vegetables. The cauliflower and broccoli give a nice crunch. Brussels sprouts add earthiness, while sweet potatoes bring sweetness. Carrots add color and texture, and peas add a pop of green. You can really taste the freshness in each bite.
Dairy and Seasoning Components
- 1 cup heavy cream
- 1 cup vegetable broth
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme
- Salt and pepper to taste
For the creamy base, I blend heavy cream with vegetable broth. This mix brings richness and depth to the dish. Garlic powder and onion powder enhance the flavor without overpowering the veggies. Dried thyme adds warmth, making each bite comforting. Adjust the salt and pepper to fit your taste.
Topping Ingredients
- 1 cup shredded sharp cheddar cheese
- 1 cup breadcrumbs (panko recommended for extra crunch)
- 2 tablespoons olive oil
The topping is key for texture. I sprinkle sharp cheddar cheese for a rich flavor. Panko breadcrumbs create a crunchy layer that contrasts beautifully with the creamy vegetables. A drizzle of olive oil helps the topping brown evenly, ensuring a golden finish. This combination makes the casserole appealing and satisfying.

Step-by-Step Instructions
Preheat the Oven
Start by setting your oven to 375°F (190°C). This step is key. It helps cook the casserole evenly. If the oven isn’t hot enough, the dish will not bake well.
Preparing the Vegetables
In a large bowl, mix the fresh vegetables. Use 2 cups of cauliflower florets, 1 cup of broccoli florets, 1 cup of halved Brussels sprouts, 1 medium sweet potato diced, 1 cup of sliced carrots, and 1 cup of frozen peas. Toss them gently to combine. This mix gives your casserole great color and flavor.
Making the Cream Mixture
In another bowl, whisk together the heavy cream and vegetable broth. Add 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and 1 teaspoon of dried thyme. Season with salt and pepper to taste. Whisk until smooth. This cream mixture brings richness to the dish.
Combining Components
Pour the cream mixture over your mixed vegetables. Use a spatula to fold the mixture gently. Make sure all the vegetables are coated well. This ensures every bite is creamy and tasty.
Transferring to Baking Dish
Spread the vegetable mix into a 9x13 inch baking dish. It is vital to create an even layer. This helps them cook evenly. If some parts are thicker than others, they may not bake properly.
Adding Cheese and Breadcrumbs
Sprinkle 1 cup of shredded sharp cheddar cheese over the veggies. Then, add 1 cup of breadcrumbs on top. Drizzle with 2 tablespoons of olive oil. This topping creates a crispy finish. It adds great texture to the creamy dish.
Baking Instructions
Cover the dish with aluminum foil. Place it in the oven and bake for 30 minutes. This allows the flavors to meld. After 30 minutes, remove the foil. Bake for another 15-20 minutes until the top is golden brown.
Cooling and Serving
Once baked, take the casserole out of the oven. Let it cool for 5-10 minutes. This resting time is important. It helps the flavors settle and makes it easier to serve. Enjoy your cozy dish!
Tips & Tricks
Best Practices for Vegetable Preparation
When selecting vegetables, look for vibrant colors and firm textures. Fresh vegetables taste the best. For this casserole, I love using:
- Cauliflower florets
- Broccoli florets
- Halved Brussels sprouts
- Diced sweet potato
- Sliced carrots
- Frozen peas
Cut the cauliflower and broccoli into bite-sized pieces. Halve the Brussels sprouts to help them cook evenly. Dice the sweet potato into 1-inch pieces to ensure all veggies cook at the same rate. Slice the carrots into rounds for a nice bite.
Enhancing Creaminess
If you want a lighter option, you can swap heavy cream for alternatives. Here are some ideas:
- Use half-and-half for a creamy texture.
- Try coconut milk for a hint of sweetness.
- Consider Greek yogurt for a tangy twist.
Each option will still keep the casserole rich and satisfying while cutting down on calories.
Achieving the Perfect Bake
To ensure even cooking, layer your vegetables evenly in the baking dish. Stir the cream mixture well to coat every piece. Cover the dish with foil for the first 30 minutes to trap steam. This helps the veggies soften.
After removing the foil, let the top crisp up. Drizzle olive oil over the breadcrumbs for a golden finish. Keep an eye on it to avoid burning. A well-baked casserole should bubble and have a crunchy top!
Pro Tips
- Use Fresh Vegetables: For the best flavor and texture, opt for fresh vegetables whenever possible. They will enhance the overall taste of your casserole.
- Customize the Cheese: Feel free to experiment with different types of cheese, such as gouda or mozzarella, for a unique twist on flavor.
- Make Ahead: This casserole can be prepared in advance. Assemble it the night before, refrigerate, and bake it when you’re ready to serve.
- Check for Doneness: To ensure your casserole is properly cooked, check that the vegetables are tender and the top is golden brown before removing it from the oven.
Variations
Protein Additions
You can add protein to make this casserole heartier. Chicken and tofu are great options. For chicken, use cooked and diced meat. Stir it in with the veggies before adding the cream. For tofu, use firm tofu. Press it to remove excess water, then cube it. Sauté the tofu until golden before mixing it in. Both options boost protein and flavor.
Flavor Enhancements
Changing herbs or spices can make this dish unique. Try rosemary for a woodsy taste, or curry powder for warmth. Basil adds a fresh note, while smoked paprika gives a nice depth. Experiment with what you have. Just remember to start with small amounts, and taste as you go. You might discover a new favorite flavor combo.
Alternative Cheese Options
Switching cheese can change the dish's flavor. Use mozzarella for a gooey texture. Pepper jack adds a spicy kick. Goat cheese lends a tangy taste and creamy texture. For a dairy-free option, try a vegan cheese. Look for brands that melt well. Each cheese offers a different twist, so choose one that suits your taste.
Storage Info
Refrigeration Guidelines
To store leftover casserole, let it cool first. Place it in an airtight container. It will keep well in the fridge for up to three days. When you want to eat it again, check the smell and look for any signs of spoilage.
Freezing Instructions
If you want to freeze this dish, use a freezer-safe container. Make sure to cool it completely. Wrap it tightly with plastic wrap and then aluminum foil to prevent freezer burn. This casserole can last up to three months in the freezer. Label your container with the date to keep track.
Reheating Tips
To reheat the casserole, you can use the oven or microwave. If you use the oven, preheat it to 350°F (175°C). Cover the dish with foil to keep it moist. Bake for about 20 to 25 minutes, or until hot. If using the microwave, heat it in short bursts, stirring in between. This helps it heat evenly. Always check the temperature before serving to ensure it’s hot throughout.
