Cook pasta according to directions. Add the broccoli within the last 2 minutes of cooking the pasta. Drain and return to the pot. Toast the bread and cut into small pieces. Place bread in a food processor and grind to make crumbs. Place crumbs on a plate and add ⅓ cup of shredded cheddar cheese.
Preheat broiler. In a medium saucepan, add milk and cornstarch stirring nicely. Let it boil then remove from heat and add the gouda, spread, butter and cheddar. Stir nicely until smooth then season with salt and pepper. Pour the sauce over the pasta and stir. Pour pasta mixture into a baking dish and sprinkle bread crumbs mixture. Broil until cheese has melted about 2 minutes. Serve
