Equipment
- Large mixing bowl – to toss vegetables
- Large skillet or sauté pan – for cooking vegetables and sauce
- Wooden spoon or spatula – for stirring
- 9×13 inch casserole dish – for baking
- Measuring cups and spoons – to ensure accurate ingredient quantities
- Knife and cutting board – to prep veggies
- Oven mitts – for safe handling
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease your casserole dish with olive oil or non-stick spray to prevent sticking.
- Prepare the vegetables: Wash and chop broccoli, cauliflower, carrots, zucchini, and onion into bite-sized pieces. Mince the garlic cloves.
- Sauté the aromatics: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced onion and minced garlic, cooking until fragrant and translucent, about 3-4 minutes.
- Add the vegetables: Toss in the broccoli, cauliflower, carrots, and zucchini. Cook for 5-7 minutes, stirring occasionally, until vegetables start to soften but remain crisp.
- Make the sauce: Sprinkle the flour over the vegetables, stirring constantly for 1-2 minutes to cook out the raw taste. Gradually pour in the vegetable broth and milk while stirring continuously to avoid lumps.
- Simmer: Reduce heat to low and let the sauce thicken, stirring frequently, about 5 minutes. Season with salt, black pepper, and dried thyme. Remove from heat.
- Combine with cheese: Stir in 1 cup of shredded cheese into the sauce mixture until melted and smooth. Reserve the remaining ½ cup for topping.
- Assemble the casserole: Transfer the vegetable mixture with sauce into the prepared casserole dish. Spread evenly.
- Add topping: Sprinkle the remaining shredded cheese and panko breadcrumbs (if using) evenly over the top for a golden crust.
- Bake: Place casserole in the oven and bake for 25-30 minutes, or until bubbly and golden brown on top.
- Garnish and serve: Remove from the oven and let cool for 5 minutes. Sprinkle chopped fresh parsley before serving.
Tips & Variations
“Feel free to swap or add any vegetables you love—bell peppers, green beans, mushrooms, or spinach work wonderfully. For a vegan version, use plant-based milk and cheese alternatives.”
Make it gluten-free: Use gluten-free flour and breadcrumbs or omit breadcrumbs altogether.
Boost the protein: Add cooked chickpeas or white beans to the veggie mixture before baking.
Extra cheesy: Mix in some cream cheese or a dollop of vegan sour cream to the sauce for a richer texture.
