This vegetable casserole is a colorful, nutritious, and kid-friendly meal perfect for lunchboxes or a quick homemade meal.

The creamy cheese topping and tender veggies make it both comforting and wholesome.
Ingredients
- 2 cups broccoli florets, chopped into small pieces
- 1 cup diced carrots
- 1 cup frozen corn kernels, thawed
- 1 cup diced zucchini
- 1/2 cup finely chopped onion
- 1 clove garlic, minced
- 1 cup cooked quinoa or rice (optional for added bulk)
- 1 cup shredded mild cheddar cheese
- 1/2 cup grated mozzarella cheese
- 1 cup milk (whole or 2%)
- 2 tablespoons all-purpose flour
- 2 tablespoons unsalted butter
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon dried oregano or Italian seasoning
- 1/4 cup breadcrumbs (optional for topping)
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish or similar sized casserole dish.
- Steam the broccoli and carrots until just tender, about 5 minutes. Drain and set aside.
- In a medium saucepan, melt the butter over medium heat. Add the chopped onion and garlic, cooking until translucent and fragrant, about 3 minutes.
- Sprinkle the flour over the butter and onion mixture, stirring constantly to make a roux. Cook for 1-2 minutes without browning.
- Slowly whisk in the milk, continuing to stir until the sauce thickens, about 4-5 minutes. Remove from heat once creamy and smooth.
- Stir in salt, pepper, and dried oregano or Italian seasoning to the sauce. Then fold in the shredded cheddar cheese until melted and combined.
- In a large bowl, combine the steamed vegetables, diced zucchini, corn, cooked quinoa or rice (if using), and the cheese sauce. Mix gently but thoroughly.
- Transfer the mixture to the prepared baking dish, spreading evenly. Sprinkle the mozzarella cheese evenly over the top, and if using, add breadcrumbs for a crunchy topping.
- Bake uncovered for 20-25 minutes, until the casserole is bubbly and the top is golden brown.
- Allow to cool slightly before serving. This helps it set and makes it easier to portion for kids.
Tips
- Vegetable substitutions: Feel free to swap in other mild vegetables like peas, sweet potatoes, or cauliflower depending on what your child prefers or what you have on hand.
- Dairy-free variation: Use a plant-based milk and dairy-free cheese alternatives to make this casserole suitable for lactose-intolerant kids.
- Make ahead: Prepare the casserole up to step 8, cover tightly with foil, and refrigerate for up to 24 hours before baking.
- Common mistake: Avoid overcooking the vegetables before baking; they should be slightly underdone when mixed in since they will cook further in the oven.
Serving Suggestions
Serve this vegetable casserole warm or at room temperature, perfect for a kid’s lunchbox or a quick meal. Pair it with a side of fresh fruit or a yogurt cup for a balanced lunch. It also goes well with a small green salad or carrot sticks for added crunch. For a heartier meal, add a boiled egg or some grilled chicken strips on the side.
Variations
You can easily customize this casserole to suit different tastes or dietary needs. Try adding cooked ground turkey or shredded chicken for extra protein. Swap quinoa with brown rice or couscous for different textures. For a Mediterranean twist, add chopped olives and sun-dried tomatoes. To make it more kid-friendly, mix in some mild salsa or ketchup into the cheese sauce. You can also experiment with different cheeses like gouda or Monterey Jack to change the flavor profile.
Storage and Reheating
Store leftover vegetable casserole in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze portions in freezer-safe containers for up to 2 months. To reheat, thaw frozen portions overnight in the fridge, then warm in a preheated oven at 350°F (175°C) for 15-20 minutes or until heated through. Alternatively, you can microwave individual portions on medium power for 2-3 minutes, stirring halfway to ensure even heating. Always check the internal temperature reaches 165°F (74°C) before serving to ensure food safety.
