Cooking time for porterhouse steak is not as lengthy as for other cuts of beef because it is a comparatively soft cut. It takes around 1 hour to sous vide a 1 1/2-inch porterhouse and 1.5 to 2 hours to sous vide a 2-inch porterhouse. Continue to soak it in the warm bath for an additional 30-60 minutes if you want.
