Beef tenderloin is considered one of the most tender, flavorful, and expensive cuts of beef Often referred to as filet mignon, this cut comes from the short loin of the cow. When properly prepared, beef tenderloin melts in your mouth and makes for an incredible entree or special occasion meal.
However, before you can cook up this delicious piece of meat, it’s crucial to know how long it takes to safely thaw beef tenderloin. Thawing is an essential first step because cooking frozen or partially frozen meat leads to uneven cooking.
In this complete guide, I’ll walk you through everything you need to know about thawing beef tenderloin, including:
- Benefits of thawing beef tenderloin
- Recommended thaw times based on size
- Safe thawing methods
- Tips for optimal results
Properly thawing beef tenderloin ensures your meat cooks evenly while maintaining texture moisture and flavor. Let’s get started!
Why Thaw Beef Tenderloin?
I’m sure we’ve all been tempted to skip the thawing step when preparing beef tenderloin. But thawing has some major advantages:
Cooks Evenly: Cooking frozen or partially frozen meat leads to uneven cooking. The exterior will overcook while the center remains underdone and cold. Thawing allows the entire cut to cook at the same rate.
Maximizes Tenderness: Slow thawing helps break down connective tissues in the meat. This leads to enhanced tenderness and a melt-in-your-mouth texture.
Improves Flavor Distribution: Seasonings and marinades penetrate deeper into the meat when thawed first. This distributes flavors more evenly.
Kills Bacteria: Thawed meat held at safe refrigerator temperatures helps kill potentially dangerous bacteria. Frozen meat could allow bacteria to survive.
So for flavorful, tender, and safely cooked beef tenderloin, proper thawing is a must!
How Long to Thaw Beef Tenderloin
Beef tenderloin can take 1-3 days to thaw thoroughly, depending on the size and thickness. Here are general guidelines:
- 1-2 pounds: 24 hours
- 3-4 pounds: 48 hours
- 5 pounds or more: 72 hours
For example, a 3-pound whole beef tenderloin may take a full 48 hours (2 days) to thaw in the refrigerator. Go by thickness as well – a 2-pound very thick roast may take closer to 36-40 hours.
I recommend erring on the side of more time rather than less. You want the meat fully thawed through to the center with no ice crystals remaining.
Tip: Check on the tenderloin’s thawing progress periodically by pressing on the center. It should feel soft and spongy when ready, with no hard, frozen sections remaining.
Safe Thawing Methods
Proper food safety is crucial when handling raw meat like beef tenderloin. Use one of these methods to safely thaw:
1. Refrigerator Thawing
This is the preferred method for any thick cuts like roasts or whole tenderloins. Simply place the frozen meat on a plate or in a pan to catch drips. Allow 24 hours per 1-2 pounds.
The cold refrigerator temperature prevents bacterial growth while slowly thawing the beef. Monitor and flip occasionally until fully thawed.
2. Cold Water Thawing
For faster thawing, submerge the beef in cold water, changing the water every 30 minutes. Allow 30 minutes per pound. A whole tenderloin could thaw in 2-3 hours.
Use cold water only – never hot water! Cook immediately after thawing is complete with this faster method.
3. Microwave Thawing
If you’re really pressed for time, you can use the defrost setting on your microwave. Refer to appliance instructions for timing, as this varies. Cook the beef immediately after microwaving.
Safety Tip: Avoid thawing at room temperature or in hot water. This puts the beef in the danger zone for bacterial growth. Refrigerator and cold water thawing are safest.
Tips for Optimizing Results
Follow these tips for properly thawed, tender, and delicious beef tenderloin every time:
-
Use a Meat Thermometer: This helps ensure the thickest section reaches 40°F or lower before cooking.
-
Dry Thoroughly: Pat the meat very dry after thawing. This helps achieve a better sear.
-
Season Generously: Rub seasonings over the entire tenderloin after thawing for the best flavor distribution.
-
Allow Marinades to Penetrate: Let meat marinate overnight in the fridge after thawing – never marinate while frozen.
-
Cook Promptly: Cook thawed beef within a few days for safety and quality. Freeze if longer storage is needed.
-
Discard if Discolored or Slimy: Do not risk eating meat that smells, looks, or feels off after thawing.
Following proper thawing methods and these tips will result in tender, juicy, and delicious beef tenderloin every time. Never skip this crucial first step!

HOW TO DEFROST FROZEN STEAKS AND MEATS
For steaks, other cuts of beef, or any other meat, letting it slowly thaw in the fridge is the best way to serve it. Our FlavorLockTM system makes sure that our steaks are frozen at their best; letting them thaw slowly keeps their high quality. To thaw your steak, just take it out of the box, put it on a plate to catch any juices, and put it in the fridge. For the best flavor, we recommend you cook your steaks immediately after defrosting.
- Let steak, burgers, and ground beef thaw in the fridge for at least 24 hours.
- You can let roasts defrost in the fridge for 3 to 4 days, depending on their size.
When you press on your steak with your thumb and it “gives,” it means they are ready to go on the grill.
How to Defrost Meat Fast
But what if you don’t have time to let the meat thaw slowly? These tips will help you get your steaks on the grill quickly.
- Cold Water Defrosting. If your steaks are still sealed in their original box, this is the fastest way to thaw them. Fill a large bowl with cold water. Submerge the meat, in its packaging, in the water. Change the water periodically. In 45 to 2 hours, your steaks should be ready to cook. Remember that the water should be cold. Warm water may be faster, but it will make a great place for bacteria to grow.
- Microwave. It’s not a good idea, but this is the fastest way to defrost meat. Follow your microwave defrosting instructions. Pay close attention, because you only want to thaw the steak and not cook it!

We do not recommend thawing steaks or roasts on the countertop.
