How to Prepare This Recipe
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). While the oven heats, wash all the vegetables thoroughly. Cut the broccoli and cauliflower into small florets, slice the carrots thinly, and dice the zucchini. Chop the onion and mince the garlic. This ensures that every vegetable cooks evenly and blends well with the cheesy sauce.
Step 2: Sauté the Vegetables
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and garlic and sauté for 2–3 minutes until fragrant. Then add the carrots, zucchini, broccoli, and cauliflower. Cook for about 5–6 minutes, stirring occasionally, until the vegetables are slightly tender. Season with salt, pepper, dried thyme, and paprika, enhancing both flavor and aroma.
Step 3: Make the Cheese Sauce
In a separate saucepan, melt 2 tablespoons of butter over medium heat. Whisk in 2 tablespoons of flour and cook for 1–2 minutes, creating a smooth roux. Gradually add 1 cup of milk, whisking constantly to avoid lumps. Stir in 1 teaspoon of mustard and cook until the sauce thickens. Remove from heat and mix in 1 cup of shredded cheddar cheese and ½ cup of grated parmesan until fully melted and smooth.
Step 4: Combine Vegetables and Sauce
Transfer the sautéed vegetables into a greased casserole dish. Pour the cheese sauce evenly over the vegetables, ensuring all pieces are coated. Gently mix with a spatula so the sauce penetrates every layer without crushing the vegetables.
Step 5: Bake the Casserole
Place the casserole in the preheated oven and bake for 25–30 minutes. The top should turn golden brown, and the cheese should be bubbling around the edges. Baking not only melts the cheese but also enhances the natural sweetness of the vegetables.
Step 6: Optional Topping
For added texture, sprinkle extra parmesan or breadcrumbs on top during the last 5 minutes of baking. This step creates a crunchy, golden crust that contrasts beautifully with the creamy interior.
Step 7: Customize as Desired
You can swap vegetables based on preference or season, such as adding bell peppers, spinach, or mushrooms. Herbs like rosemary or basil can replace thyme to change the flavor profile slightly. Turkey bacon bits or chicken ham can also be added for a heartier version.
Step 8: Serve and Enjoy
Remove the casserole from the oven and let it rest for 5 minutes. This allows the sauce to thicken slightly and makes serving easier. Portion into individual servings and enjoy warm.
Step 9: Popular with Many
This casserole is a crowd-pleaser for both adults and children. Its creamy texture, cheesy flavor, and vegetable goodness make it perfect for family dinners, potlucks, or holiday gatherings. Its combination of comfort and nutrition ensures it will be requested repeatedly.

FAQs
1. Can I make this casserole ahead of time?
