Method
- Heat the oven to 350°F.
- Grease a 9x13-inch baking dish with 1 tablespoon softened butter.
- Bring the water to a boil in a large pot.
- Add the macaroni and 1 tablespoon salt, and cook until 2 minutes shy of al dente.
- Drain the macaroni well.
- Toss the drained macaroni with the 2 tablespoons melted butter.
- In a large bowl, whisk the eggs, evaporated milk, whole milk, remaining 3/4 teaspoon salt, black pepper, and dry mustard until combined.
- Spread half the macaroni in the prepared dish.
- Scatter half of both cheeses over the macaroni.
- Repeat with the remaining macaroni and cheeses.
- Pour the egg mixture evenly over the top.
- Bake for 35 to 45 minutes, until the center reaches 160°F and the top is golden and bubbling at the edges.
- Let the casserole rest for 10 minutes before serving.
Notes
For the best texture, freshly grate the cheeses so they melt smoothly. Refrigerate leftovers for 3–4 days; freezer: yes. For a gluten-free option, use gluten-free elbow macaroni.
