One is 4.45 pounds the other is 4.04 pounds. They are both trimmed. Can I cook them together putting one in a little bit longer for those who want med rare? Should they be tied? How long and at what temperature? Thanks.
This is what gives me best success for roasting beef tenderloin
Let beef stand at room temperature 1 hour before roasting. Position rack in center of oven and preheat to 425°F. Rub beef all over with oil; sprinkle with 2 tablespoons cracked peppercorns, pressing to adhere. Return beef to rack on baking sheet and roast until instant-read thermometer inserted into thickest part of meat registers 125°F for medium-rare (135°F to 140°F in thinnest part), about 30 minutes. Remove roast from oven and let rest 15 minutes.

Regarding tying, if they aren't an even thickness I would tie. Hope this helps!
