Instructions
- 1Bring a large saucepan of water to a boil over high heat and season well with salt. Add the pasta and cook for 1 minute less than the packet instructions. Drain and set aside. Meanwhile, continue to the next step.
- 2Melt 1 oz of the butter and add to the breadcrumbs, stir to coat and set aside.
- 3Grease a 8-inch square baking dish with softened butter.
- 4To make the cheese sauce, melt the remaining 1 oz butter in a saucepan over medium heat. Add the flour and whisk constantly for 2 minutes, or until it bubbles. Gradually add the milk whisking constantly to prevent lumps. Add the thyme and reduce the heat to medium-low and cook, whisking for 5 minutes, or until the sauce boils and thickens slightly.
- 5Remove the pan from the heat. Add ½ teaspoon salt, mustard powder, cayenne pepper and both cheeses. Whisk until the cheese has melted and the sauce is smooth. Remove and discard the thyme sprigs.
Tip: If the cheese is not completely melted, return the pan to low heat and whisk until just melted, do not overheat as the cheese will split and become grainy.
- 6Insert the oven rack into position 3 Up. Set the oven to Roast & Bake, Super Convection, 400°F, for 10 minutes and press Start to preheat. Meanwhile, continue to the next step.
- 7Add the pasta to the cheese sauce and stir until well combined.
- 8Spread the mixture into the prepared dish and sprinkle with the crumbs.
- 9Once preheated, place the dish in the oven and bake for 10 minutes.
- 10The crumb topping should be golden brown. If not, press A Bit More. When it’s ready, remove from the oven and stand for 10 minutes.Tip: It may need a little more or a little less extra cooking time, best to keep an eye on it.
- 11Serve sprinkled with chives.
