Ingredients
Method
- Cook the pasta per box instructions, but slightly undercooked so it isn't mushy.
- Rinse the pasta under cold water. Place in a bowl or deep dish with a drizzle of oil to stop cooking and prevent sticking.
- Melt the butter in a deep pot over medium heat. Add the sifted flour and whisk until it pulls away from the sides of the pot.
- Pour in the cold milk and heavy cream very slowly, stirring constantly.
- Keep cooking and stirring until it boils and thickens, about 5 to 10 minutes.
- Add the seasonings.
- Turn the heat to very low. Stir in the cheddar, Colby and Gruyère until melted, keeping 1/2 cup cheddar for topping. Shredded is best, but cubed works too.
- Taste the sauce and add a pinch of salt if needed.
- Preheat the oven to 400°F.
- Mix the pasta evenly into the sauce and transfer to a casserole. Cover the top with the grated Parmesan and the reserved shredded cheddar.
- Bake 35 to 40 minutes, until brown and crispy on top.
- Rest 5 minutes out of the oven before serving.
Notes
Use block sharp cheddar and shred it fresh, not pre-shredded. Cold milk and cream are important. Never stop stirring the sauce, or it will stick or go lumpy.
Total time: 1 hour 15 minutes.
