What temperature should a filet mignon roast be cooked at?

You can't really cook a filet mignon as a "roast." Filet mignon is a cut of meat that's best cooked as a steak.

Here's why:

* Size: Filet mignon is a small, tender cut, typically meant for individual servings. It's not large enough to be considered a roast.

* Cooking method: Roasts are typically cooked at lower temperatures for longer periods to allow the meat to become tender and flavorful. Filet mignon, being very tender, is best cooked quickly over high heat to achieve a nice sear and rare to medium-rare doneness.

Here's the ideal temperature for cooking filet mignon steak:

* High Heat: Use a cast iron skillet or grill preheated to high heat (around 450-500°F/232-260°C).

* Cooking Time: Aim for 3-5 minutes per side for a medium-rare steak (130-135°F/54-57°C internal temperature).

Important Note: Use a meat thermometer to ensure your steak is cooked to your desired doneness.
