How Long to Cook a 1.4 kg Roast Beef to Perfection

Roast beef is a beloved centerpiece for holidays, dinner parties and special occasion meals. When properly prepared, it emerges from the oven tender, juicy and full of rich, meaty flavor.

But learning how long to cook a 1.4 kg roast beef can be tricky. Follow too little time and the center remains raw. Too long in the oven and you end up with an overcooked, dried-out roast.

So what is the ideal roast beef cooking time for a 14 kg cut? How do you ensure it turns out perfectly medium-rare every time? This guide has you covered,

How Long Should You Cook a 1.4 kg Roast Beef?

A 1.4 kg roast beef converts to approximately 3 pounds. The general guideline for roasting beef is:

15-20 minutes per pound at 350°F

So for a 1.4 kg/3 pound roast, the estimated cooking time would be:

  • 45-60 minutes

However, cooking times are always a range since shape, thickness, bone-in vs boneless and doneness preference all affect total time. The only way to be certain your roast beef is cooked properly is to use a meat thermometer.

Use a Thermometer for Guaranteed Doneness

While cooking time ranges provide a starting point, using an instant-read thermometer is the surest way to perfectly roast beef.

Insert the thermometer into the thickest part of the roast halfway through cooking. Cook until it reaches your desired internal temp:

  • 120-125°F for rare
  • 130-135°F for medium-rare
  • 140-150°F for medium

This helps you pull the roast from the oven at just the right moment regardless of variances in size, shape or cook time.

Factor in Carryover Cooking

Since the internal temperature continues rising as the roast rests pull it from the oven 5-10°F below your target doneness. For medium-rare, remove from oven at 125-130°F and let carryover cooking bring it up to a perfect 135°F.

Allow at least 15 minutes resting time before slicing into the roast. Tent loosely with foil to keep warm.

Add Time For Bone-In Roasts

Bone-in roasts take longer to cook since the bone shields some of the meat. For a bone-in 3 pound roast, extend cooking time to:

  • 60-75 minutes

The bone also imparts extra flavor and gives an elegant presentation.

Reduce Time for Smaller Roasts

Larger roasts require more roast time than smaller cuts since the center takes longer to reach ideal doneness. For petite 2 pound roasts, shorten cooking time to:

  • 30-40 minutes

Always rely on a meat thermometer for accurately determining when the roast is done.

How to Tell Doneness Without a Thermometer

If a thermometer isn’t available, use these visual indicators to test for desired doneness:

  • Rare – Bright red center, soft to the touch
  • Medium-Rare – Warm red-pink center, slightly firmer
  • Medium – Hot pink center, firm when pressed
  • Well – Brown-gray center, very firm

Cut into the thickest part of the roast if unsure. Cook longer if needed to reach preferred internal color and texture.

Tips for Roasting Beef to Perfection

Follow these tips for phenomenal roast beef every time:

  • Bring roast to room temp before cooking for even heating.
  • Generously season exterior with salt, pepper and herbs.
  • Sear all sides in a hot skillet before roasting to boost flavor.
  • Roast fat-side up on a rack in a shallow pan.
  • Baste with pan drippings 2-3 times during roasting.
  • Allow meat to rest before slicing for juicy, tender meat.

With the proper roasting time, temperature monitoring and resting, you’ll achieve tender, juicy roast beef encased in a flavorful crust perfection. For more roasting guides and recipes, check out
