The baking time for mac and cheese at 400°F (200°C) can vary depending on the recipe, the size of the dish, and the desired level of doneness. Here are some general guidelines:

* For a small to medium-sized dish (6-8 inches in diameter, 2-3 inches deep), bake for 20-25 minutes.
* For a medium-sized dish (8-10 inches in diameter, 2-3 inches deep), bake for 25-30 minutes.
* For a large dish (10-12 inches in diameter, 2-3 inches deep), bake for 30-35 minutes.

It’s also important to check the mac and cheese for doneness by looking for the following signs:

* The top is golden brown and crispy.
* The mac and cheese is heated through and the cheese is melted and bubbly.
* The pasta is cooked al dente.

You can also check the internal temperature of the mac and cheese to ensure it reaches a safe minimum internal temperature of 165°F (74°C).

Keep in mind that these are general guidelines, and the baking time may vary depending on your specific recipe and oven. It’s always a good idea to check the mac and cheese frequently to avoid overcooking.
