1. Preheat oven to 425 degrees Fahrenheit (220 degrees Celsius). Spray two large baking sheets with cooking spray.
2. In a large mixing bowl, toss vegetables with olive oil and sprinkle with garlic powder, salt, and pepper.
3. Once coated, spread evenly over the two baking sheets. Roast for 20 minutes. Swap racks for even cooking and roast for an additional 20–25 minutes or until veggies are tender and browning on top.
4. Meanwhile, prepare the cheese sauce: Melt butter in a medium saucepan. Add flour and whisk together with melted butter, mixing quickly to prevent burning.
5. Once combined, pour in milk and bring to a low boil, cooking until thickened, about five minutes.
6. Add shredded cheese and spices and mix well until cheese is melted.
7. Remove vegetables from oven and drizzle about 1/2 cup of hot cheese sauce over each pan. Return to oven for an additional five minutes. Serve immediately.
LOVE this recipe, I have made it a couple of times, sometimes with the veggies and sometimes with tortilla chips and nacho toppings like beans, jalapenos, and guacamole. Also a success and loved by all!
Is there any way this can be prepared in advance and warmed up on a hot plate on yom tov?
