Flank steak stuffed and rolled before roasting needs time to reach a safe internal temperature without overcooking the outer layers of meat. So how long to cook stuffed flank steak in oven? Most rolled flank steaks take 35 to 45 minutes at 350°F (175°C), depending on thickness and filling.
That range is a starting point, not a rule set in stone. The real answer depends on how tight you roll it, how much filling you use, and how hot your oven actually runs.
Below you’ll find a full time and temperature guide, plus step-by-step cooking instructions and tips to keep the meat juicy.
How Long To Cook Stuffed Flank Steak In Oven
Oven time varies with size and filling, but this chart covers most home kitchens. Always confirm doneness with a meat thermometer, not just the clock.
- 350°F (175°C): 35 to 45 minutes for a 1.5 to 2 pound roll
- 375°F (190°C): 30 to 40 minutes for the same size
- 400°F (205°C): 25 to 35 minutes, best for thinner rolls
- Target internal temp: 130°F (54°C) for medium rare, 135°F to 140°F (57°C to 60°C) for medium
Pull the steak out when it reads 5 degrees below your target. Carryover cooking will finish the job while it rests.
Why Flank Steak Needs Careful Timing
Flank is a lean, fibrous cut. It has little fat to keep it moist, so it dries out fast when overcooked.
Rolling the meat adds another problem. The outer layer sits close to the oven heat while the center takes much longer to warm through. If you cook by time alone, the outside turns gray and tough before the middle is safe.
A thermometer solves this. It tells you exactly when the center is ready, no guessing involved.
Factors That Change Cooking Time
No two stuffed flank steaks cook the same. Here’s what moves the needle:
- Thickness of the roll: A fat, tightly rolled steak needs more time than a thin one
- Filling type: Cold or dense fillings like sausage slow the center down
- Filling amount: More stuffing means a thicker roll and longer cooking
- Oven accuracy: Many ovens run 25 degrees off, hot or cold
- Pan and rack: A rack lets heat circle the meat, a solid pan does not
- Starting temp: Let the roll sit at room temperature for 20 to 30 minutes first
Step-By-Step Cooking Instructions
Follow these steps for a roll that’s browned outside and juicy in the middle.
- Preheat your oven to 350°F (175°C). Place a rack inside a rimmed baking sheet.
- Lay the stuffed and rolled flank steak seam side down. Tie it with kitchen twine every 2 inches.
- Pat the surface dry with paper towels. Dry meat browns better.
- Season the outside with salt, pepper, and a little oil.
- Sear the roll in a hot skillet for 2 minutes per side, if you want a crust. This step is optional but adds flavor.
- Transfer the steak to the rack on the baking sheet.
- Roast for 35 minutes, then check the internal temperature.
- Continue cooking in 5 minute increments until the center hits 130°F (54°C) for medium rare.
- Rest the steak for 10 minutes before slicing. This keeps the juices inside.
- Slice against the grain into 1 inch rounds.
Total time from oven to table: about 50 to 60 minutes including resting.
How To Tell When It’s Done
Use an instant-read thermometer inserted into the thickest part of the meat, not the filling. The filling can be hotter or cooler than the steak itself.
If you don’t own a thermometer, press the center with a finger. A medium rare roll feels springy with slight give. A firm, unyielding roll is overcooked.
You can also slice a small test piece from one end. The center should be pink and slightly soft, not gray all the way through.
Common Mistakes To Avoid
- Overstuffing the roll, which makes it too thick to cook evenly
- Skipping the rest, which lets juices run out on the board
- Cooking by time only and ignoring the thermometer
- Using a cold filling straight from the fridge
- Slicing with the grain, which makes every bite chewy
Make-Ahead And Reheating Tips
You can assemble the roll up to 24 hours ahead. Wrap it tight and keep it in the fridge.
Add 5 to 10 minutes to the cook time if it goes into the oven cold.
For leftovers, reheat slices gently in a 300°F (150°C) oven for 8 to 10 minutes. A hot skillet works too, but keep it brief so the meat doesn’t dry out.
Stuffed flank steak also tastes great cold in sandwiches the next day.
Final Timing Summary
For a 1.5 to 2 pound stuffed flank steak, plan on 35 to 45 minutes at 350°F (175°C).
Check the internal temperature at the 35 minute mark. Pull it at 130°F (54°C) for medium rare, then rest for 10 minutes.
If your roll is thicker or packed with a heavy filling, add 5 to 10 minutes. If it’s thin, start checking at 25 minutes.
With a thermometer and a little patience, you’ll get a tender, evenly cooked roll every time. The oven time is just a guide, your thermometer is the real answer.
