Christmas beef tenderloin dinner timeline
A beef tenderloin is the quick Christmas roast. At 425 °F it takes an hour or less up to 5 lb, and that is the same temperature roast potatoes and carrots want. So the roast and the vegetables can sit in the oven together, and the order of work is easier than with a slow roast. The tables below put clock times on it by weight and by dinner time.
What the times rest on
- Oven and time: Safeway, how to roast perfect beef calls tenderloin a high-heat cut (425–450 °F) and gives "10-12 minutes per pound for medium-rare". The plan uses 425 °F and the long end, 12 minutes per pound. A thin tail end of the roast cooks faster than the middle, so the thermometer decides.
- Pull temperature: Safeway's chart says 125–130 °F for medium-rare (finishing near 135 °F), though its roasting steps say 120–125 °F, so the thermometer and your taste decide.
- Rest: the guide says a minimum of 15 to 30 minutes, loosely tented with foil. The plan rests the roast 20 minutes and lets it wait up to 45 minutes before carving. That 45 is my assumption, so the vegetables have time to finish.
- Before roasting: the guide says to take roasts over 3 lb out of the fridge 2 to 3 hours ahead. The "fridge out" column uses 3 hours.
- The guide also describes a hotter start for prime rib (475 °F for the first 15 to 20 minutes). The planner holds one temperature per dish, so the tables use plain 425 °F.
- The side dishes are example recipe times, not sourced: potatoes 45 minutes, carrots 30, Brussels sprouts 25, creamed spinach 15 on the stovetop. The oven needs 15 minutes to change temperature.
- The safe minimum for beef roasts is 145 °F according to the USDA. I could not open the FSIS page, so check the FSIS safe temperature chart and choose your own target.
When the tenderloin goes in, by weight
For a 6 PM dinner, with the vegetables in the oven beside it. A heavier roast goes in earlier but comes out at the same time, 5:35 PM, and the roast potatoes go in at 5:15 PM in every row.
| Roast | Roasting time | Fridge out | Roast in | Start checking | Roast out |
|---|---|---|---|---|---|
| 3 lb | 30 to 36 min | 1:59 PM | 4:59 PM | 5:29 PM | 5:35 PM |
| 4 lb | 40 to 48 min | 1:47 PM | 4:47 PM | 5:27 PM | 5:35 PM |
| 5 lb | 50 to 60 min | 1:35 PM | 4:35 PM | 5:25 PM | 5:35 PM |
| 6 lb | 60 to 72 min | 1:23 PM | 4:23 PM | 5:23 PM | 5:35 PM |
The roasting time is the weight times 10 and 12 minutes (my arithmetic). "Start checking" uses the short end, 10 minutes per pound. An early finish is easy to hold under foil, so check early.
When to start, by dinner time
For a 4 lb tenderloin (40 to 48 minutes). Moving dinner moves every step by the same amount.
| Dinner | Oven on | Roast in | Potatoes in | Roast out |
|---|---|---|---|---|
| 3:00 PM | 1:32 PM | 1:47 PM | 2:15 PM | 2:35 PM |
| 4:00 PM | 2:32 PM | 2:47 PM | 3:15 PM | 3:35 PM |
| 5:00 PM | 3:32 PM | 3:47 PM | 4:15 PM | 4:35 PM |
| 6:00 PM | 4:32 PM | 4:47 PM | 5:15 PM | 5:35 PM |
| 7:00 PM | 5:32 PM | 5:47 PM | 6:15 PM | 6:35 PM |
Full checklist: 4 lb tenderloin, 6 PM dinner
The tenderloin goes in at 4:47 PM and the oven stays at 425 °F all evening. The potatoes join it at 5:15 PM, the carrots and sprouts follow, and the roast leaves at 5:35 PM to rest while the vegetables finish. The creamed spinach runs on the stovetop at the end. The planner allows three dishes in the oven at once, which you can change in the link below.
| Time | Step |
|---|---|
| 4:32 PM | Preheat the oven to 425 °F |
| 4:47 PM | Put Beef tenderloin, 4 lb in the oven (425 °F, 48 min) |
| 5:15 PM | Put Roast potatoes in the oven (425 °F, 45 min) |
| 5:30 PM | Put Roasted carrots in the oven (425 °F, 30 min) |
| 5:35 PM | Take Beef tenderloin, 4 lb out (25 min before serving) |
| 5:35 PM | Put Roasted Brussels sprouts in the oven (425 °F, 25 min) |
| 5:45 PM | Start Creamed spinach on the stovetop (15 min) |
| 6:00 PM | Creamed spinach: ready |
| 6:00 PM | Take Roast potatoes out |
| 6:00 PM | Take Roasted carrots out |
| 6:00 PM | Take Roasted Brussels sprouts out |
| 6:00 PM | Serve |

When a 350 °F side joins the menu
Add a green bean casserole (350 °F, 35 minutes, example time) and the plan breaks. The planner cannot keep the roast and the casserole in together, so it bakes the casserole after the roast and pulls the tenderloin at 4:10 PM, 1 h 50 min before dinner. That is far past the 45 minutes the plan allows the roast to wait, and the casserole is flagged too.
My suggestions, none of them sourced:
- Choose sides that roast at 425 °F, or need no oven at all, such as mashed potatoes or creamed spinach.
- Bake the casserole the day before and warm it in a second oven or a roaster oven, if you have one.
- Turn the oven down to 350 °F after the roast comes out. The planner counts 15 minutes for a change, so check what that does to the potatoes.
