Mac and Cheese

Yes—assemble completely in the baking dish, cover tightly with plastic wrap and foil, and refrigerate for up to 2 days or freeze for up to 3 months. Bake from the fridge covered at 350°F for 30 minutes, then uncovered for 10 minutes until hot and the top is golden; add 10 minutes if frozen.

Sharp aged cheddar is essential for flavor; avoid mild cheddar as it will taste flat. Gruyère adds nutty complexity, and Parmesan provides sharpness and helps the sauce set. Do not use pre-shredded cheese—it contains anti-caking agents that prevent a smooth sauce.

The heat was too high, causing the cheese to separate and oil to break from the proteins. Cook the roux and milk mixture over medium heat, never high, and melt the cheese over low heat while stirring constantly; add milk or cream a splash at a time if it does break.

Crispy bacon bits (1 cup), fresh thyme, sautéed mushrooms (1 cup), or a pinch of smoked paprika all work beautifully stirred into the sauce before baking. Do not overload it—one or two additions keeps the dish focused.

Yes—skip the breadcrumb topping and simply stir the cooked pasta into the cheese sauce in the pot over low heat until creamy. Serve immediately; it will thicken as it cools, so keep the heat low and the sauce looser than you think you need.

Cover and refrigerate for up to 4 days. Reheat a portion covered with foil in a 350°F oven for 15–20 minutes, or in a microwave at 50% power for 2–3 minutes, adding a splash of milk to restore creaminess.
