Ingredients
Method
- Begin by preheating your oven to 375°F. Drizzle vegetable oil into a large pot of boiling salted water, then add 1 lb of elbow macaroni or cavatappi pasta and cook according to the package directions, typically 6 to 8 minutes, until al dente.
- While the pasta cooks, heat 1 quart of milk in a small saucepan without allowing it to boil. Drain the cooked pasta well and set aside.
- In a large 4-quart pot, melt 6 tablespoons of unsalted butter over low heat and add 1/2 cup of all-purpose flour, stirring constantly with a whisk for about 2 minutes to create a roux.
- Gradually whisk in the hot milk, continuing to stir for another minute or two until the sauce thickens and becomes smooth.
- Remove from heat and stir in 12 ounces of grated Gruyere cheese, 8 ounces of grated extra-sharp Cheddar cheese, 1 tablespoon of salt, 1/2 teaspoon of fresh ground black pepper, and 1/2 teaspoon of ground nutmeg.
- Add the cooked macaroni to the cheese sauce and stir until all pasta is thoroughly coated. Pour the mixture into a 3-quart baking dish.
- Arrange sliced fresh tomatoes (about 3/4 lb or 4 small tomatoes) on top of the mac and cheese.
- Melt the remaining 2 tablespoons of butter and combine with 1 1/2 cups of fresh white breadcrumbs, then sprinkle this mixture evenly over the top.
- Bake for 30 to 35 minutes until the sauce is bubbly and the top is golden brown.
