Cook Macaroni: Boil macaroni until tender, then drain.

Make the Sauce: In a separate pot, melt butter and stir in flour to create a roux. Slowly add milk and cream, stirring constantly.

Season: Add salt, pepper, and a pinch of nutmeg to the sauce, adjusting to taste.

Cheese Blend: Gradually stir in both grated cheddar and Parmesan until the sauce is smooth and velvety.

Combine: Mix the cooked macaroni with the cheese sauce until every noodle is coated in the luscious blend.

Bake: Transfer the mixture to a baking dish and bake at 350°F (175°C) until the top is golden and bubbly.
