REALLY GOUDA MAC AND CHEESE

Steps:

• Melt 1 tablespoon butter on a griddle over medium-high heat. Add bread and cook until toasted, 1 to 2 minutes per side. Set aside to cool.
• Preheat the oven to 350 degrees F (175 degrees C). Coat a 9x13-inch baking pan with cooking spray.
• Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally, until tender yet firm to the bite, about 8 minutes. Drain macaroni and transfer to a large bowl.
• Place cooled toast in a resealable bag and slowly crush with the bottom of a saucepan or a rolling pin. Set bread crumbs aside.
• Mix Cheddar and Gouda cheeses together and divide into 4 equal piles.
• Melt 1/2 cup butter in a saucepan over medium heat.
• While butter is melting, whisk 1 cup milk and cornstarch together in a bowl until cornstarch has dissolved. Add milk-cornstarch mixture to the melted butter. Gradually mix in remaining 1/2 cup milk and half-and-half. Cook, whisking continuously, until mixture thickens to the consistency of a milkshake, 3 to 5 minutes. Add 2 piles of cheese, one at a time, whisking after each addition until cheese has completely melted.
• Pour cheese sauce over cooked macaroni and mix to coat. Transfer 1/2 of the mac and cheese mixture to the reserved baking pan and spread evenly. Sprinkle 1 pile of cheese over top. Evenly distribute the rest of the mac and cheese mixture into the pan, sprinkle with remaining cheese, and top with reserved breadcrumbs.
• Bake in the preheated oven until golden and bubbly, 15 to 20 minutes.
