| Garlic cloves | 3 | Minced |
| Olive oil | 2 tablespoons | For sautéing |
| All-purpose flour | 3 tablespoons | For thickening sauce |

| Shredded cheese (cheddar or mozzarella) | 1 ½ cups | Optional for topping |

| Black pepper | To taste | |
| Dried thyme | 1 teaspoon | For flavor |

Equipment
- Large skillet – for sautéing vegetables
- Mixing bowls – to combine ingredients
- Measuring cups and spoons – for precision
- 9×13 inch casserole dish – ideal baking vessel
- Whisk – for sauce preparation
- Knife and cutting board – for veggie prep
- Oven mitts – safety first
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease your 9×13 inch casserole dish to prevent sticking.
- Prepare the vegetables: Wash and slice the zucchini, yellow squash, carrots, and red bell pepper. Chop the onion and mince the garlic cloves.
- Sauté the aromatics: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and garlic and cook until fragrant and translucent, about 3-4 minutes.
- Add the vegetables: Stir in the sliced zucchini, yellow squash, carrots, broccoli florets, and diced red bell pepper. Cook for 5-7 minutes, stirring occasionally, until the veggies start to soften but still retain some bite.
- Make the sauce: Sprinkle the flour over the veggies in the skillet and stir well to coat. Slowly pour in the milk while whisking continuously to avoid lumps. Cook for about 3-5 minutes until the sauce thickens.
- Season the mixture: Add salt, black pepper, dried thyme, and paprika to taste. Adjust seasoning as needed.
- Assemble the casserole: Transfer the vegetable and sauce mixture into the prepared casserole dish, spreading it evenly.
- Add toppings: Sprinkle shredded cheese evenly over the top if using. Then, cover the cheese layer with breadcrumbs for a crispy finish.
- Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbly around the edges.
- Cool and serve: Remove the casserole from the oven and let it cool for 5-10 minutes before serving. This helps the casserole set and makes it easier to portion.
Tips & Variations
“Don’t be afraid to experiment with different vegetables or add your favorite herbs for a unique flavor profile.”
For a dairy-free version, substitute the milk with unsweetened almond, soy, or oat milk, and omit the cheese or use a plant-based alternative. You can also swap the breadcrumbs for crushed nuts or gluten-free crumbs if needed.
If you enjoy a creamier texture, consider making a Vegan Bechamel Sauce to mix in with your vegetables instead of the flour and milk method.
For added protein, consider mixing in cooked lentils or chickpeas into the casserole before baking. A sprinkle of nutritional yeast also adds a savory, cheesy flavor for vegan eaters.
To add a bit of zest, toss in fresh herbs like basil, parsley, or rosemary just before baking. Also, if you love spicy food, a dash of cayenne pepper or chili flakes will give the casserole a nice kick.
