Internal Temperature vs. Cooking Time
While cooking time is an essential factor in cooking a beef tenderloin, it’s not the only factor. Internal temperature is also crucial in determining the doneness of the meat. Here’s a table that shows the internal temperature for each level of doneness:
| Level of Doneness | Internal Temperature |
|---|---|
| Rare | 120°F – 130°F (49°C – 54°C) |
| Medium-rare | 130°F – 135°F (54°C – 57°C) |
| Medium | 140°F – 145°F (60°C – 63°C) |
| Medium-well | 150°F – 155°F (66°C – 68°C) |
| Well-done | 160°F – 170°F (71°C – 77°C) |
Using a Meat Thermometer
To ensure that your beef tenderloin is cooked to a safe internal temperature, it’s essential to use a meat thermometer. A meat thermometer is a tool that measures the internal temperature of the meat. Here’s how to use a meat thermometer:
- Insert the thermometer into the thickest part of the meat, avoiding any fat or bone.
- Wait for a few seconds until the temperature stabilizes.
- Read the temperature on the thermometer.
- Compare the temperature to the desired internal temperature for your level of doneness.

What is the ideal internal temperature for a 1.5 lb beef tenderloin?
The ideal internal temperature for a 1.5 lb beef tenderloin depends on the level of doneness desired. For medium-rare, the internal temperature should be at least 130°F – 135°F (54°C – 57°C), while medium should be at 140°F – 145°F (60°C – 63°C). It’s essential to use a meat thermometer to ensure the tenderloin reaches a safe internal temperature.
It’s also important to note that the internal temperature will continue to rise slightly after the tenderloin is removed from the oven. This is known as carryover cooking. To account for this, it’s best to remove the tenderloin from the oven when it reaches an internal temperature that is 5°F (3°C) lower than the desired temperature.
How do I season a 1.5 lb beef tenderloin for optimal flavor?
To season a 1.5 lb beef tenderloin, start by rubbing the tenderloin with a mixture of salt, pepper, and any other desired herbs and spices. Let the tenderloin sit at room temperature for about 30 minutes to allow the seasonings to penetrate the meat. You can also add aromatics like garlic, thyme, and rosemary to the tenderloin for added flavor.
When seasoning the tenderloin, be sure to coat it evenly and avoid over-seasoning. You can also let the tenderloin marinate in the refrigerator for several hours or overnight to allow the flavors to meld together. Just be sure to pat the tenderloin dry with paper towels before cooking to remove excess moisture.
What is the best way to cook a 1.5 lb beef tenderloin?
The best way to cook a 1.5 lb beef tenderloin is to use a combination of high heat and gentle cooking. Start by searing the tenderloin in a hot skillet with some oil to create a crust on the outside. Then, finish cooking the tenderloin in the oven at a moderate temperature, such as 400°F (200°C). This will help to cook the tenderloin evenly and prevent it from becoming too well done.
Alternatively, you can also cook the tenderloin entirely in the oven or on the grill. However, searing the tenderloin in a skillet first will help to create a more flavorful crust on the outside. Regardless of the cooking method, be sure to use a meat thermometer to ensure the tenderloin reaches a safe internal temperature.
How long does it take to cook a 1.5 lb beef tenderloin?
The cooking time for a 1.5 lb beef tenderloin will depend on the level of doneness desired and the cooking method used. Generally, a 1.5 lb beef tenderloin will take about 20-25 minutes to cook in the oven at 400°F (200°C) for medium-rare. If cooking the tenderloin entirely in a skillet, it may take about 10-15 minutes per side for medium-rare.
It’s essential to use a meat thermometer to ensure the tenderloin reaches a safe internal temperature. You can also check the tenderloin’s doneness by cutting into it, but this can let juices escape and make the tenderloin less tender. To avoid overcooking, it’s best to err on the side of undercooking and let the tenderloin rest for a few minutes before slicing.
Can I cook a 1.5 lb beef tenderloin from frozen?
While it’s technically possible to cook a 1.5 lb beef tenderloin from frozen, it’s not recommended. Cooking a frozen tenderloin can lead to uneven cooking and a less tender final product. Additionally, frozen tenderloins may contain more moisture, which can make them more prone to overcooking.
If you need to cook a frozen tenderloin, it’s best to thaw it first in the refrigerator or under cold running water. Then, pat the tenderloin dry with paper towels and cook it as you would a fresh tenderloin. Keep in mind that cooking a frozen tenderloin may take longer than cooking a fresh one, so be sure to adjust the cooking time accordingly.
How do I slice a 1.5 lb beef tenderloin?
To slice a 1.5 lb beef tenderloin, start by letting it rest for about 10-15 minutes after cooking. This will allow the juices to redistribute and the tenderloin to retain its tenderness. Then, slice the tenderloin against the grain using a sharp knife. Cutting against the grain will help to create more tender slices.
When slicing the tenderloin, try to slice it in a smooth, even motion. Apply gentle pressure to the knife and let it do the work. You can also use a meat slicer or a sharp carving knife to slice the tenderloin. To serve, slice the tenderloin into thin medallions or slices, depending on your preference.
How do I store leftover beef tenderloin?
To store leftover beef tenderloin, let it cool to room temperature first. Then, wrap the tenderloin tightly in plastic wrap or aluminum foil and refrigerate it within two hours of cooking. Cooked beef tenderloin can be stored in the refrigerator for up to three days.
If you don’t plan to use the leftover tenderloin within three days, you can also freeze it. Wrap the tenderloin tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. Frozen cooked beef tenderloin can be stored for up to three months. When reheating, be sure to heat the tenderloin to an internal temperature of at least 165°F (74°C) to ensure food safety.
