Part 1: Understanding the Basics

What is Tenderloin?

Tenderloin, also known as "filet mignon," is a long, narrow cut of meat taken from the tenderloin muscle of a cow. Think of it as the Rolls-Royce of beef cuts - it’s the most tender cut you can get, hence the name. It's naturally lean and has a delicate flavour, which makes it a popular choice for special occasions. I mean, who doesn't love a juicy, perfectly cooked steak, especially when it's a tenderloin? It's truly a culinary masterpiece.

Why You Need to Know Your Cooking Times

The key to getting a tenderloin perfectly cooked is knowing your cooking times. Overcooking this delicate cut will result in a tough, dry steak, which is a complete tragedy, let me tell you. It’s like a beautiful painting ruined by a careless hand. Undercooking, on the other hand, can be a bit risky. So, understanding how long it takes to cook your tenderloin to the desired level of doneness is crucial. This is like knowing how long to bake a cake - you don’t want it to be undercooked or burned!

Part 2: Choosing and Preparing Your Tenderloin

Choosing the Right Tenderloin

First things first, you need to choose the right tenderloin. This is like picking a good book - you want to make sure it's high quality and will deliver a delicious read! Look for a cut that's bright red in colour, has good marbling (those streaks of fat), and is firm to the touch. Think of the marbling as the flavourful highlights in your steak! Avoid any tenderloin that has a dull colour, is dry, or has an off smell. It's a good idea to ask your butcher for advice. They know their meat! They’re like the experts in the book world, guiding you towards the best reads.

Preparing the Tenderloin for Cooking

Once you've got your tenderloin, it's time to prepare it for cooking. This usually involves trimming any excess fat and seasoning it with salt and pepper. Think of this as getting your book ready for reading - you need to prepare it for the experience! You can also add other seasonings, depending on your taste. Some people like to use garlic powder, onion powder, or even a bit of paprika. I love adding a little bit of smoked paprika for a smoky flavour, it’s like adding a touch of suspense to your culinary adventure.

Now, if you're feeling fancy, you can tie the tenderloin with kitchen twine to keep it from unraveling during cooking. This is especially helpful if you're cooking a large tenderloin. This is like putting a bookmark in your book - it keeps everything organized and prevents any surprises! But, honestly, it's not a dealbreaker if you're cooking a smaller one.

Part 3: Cooking Methods and Temperature

Oven Cooking

Now, let's talk about cooking methods. Oven cooking is a great option for tenderloin, as it allows for even cooking and helps to keep the meat juicy. Think of the oven as a warm, cozy fireplace for your steak. Preheat your oven to 400°F (200°C). Place the seasoned tenderloin on a baking sheet and cook for about 15-20 minutes per pound.

To make sure you get that perfect crust, you can sear the tenderloin in a hot pan before putting it in the oven. I like to use a cast-iron skillet for this, but any heavy-bottomed pan will do. Searing creates a beautiful crust on the outside, like a crisp cover for your book.

Grill Cooking

If you're a grilling enthusiast, you can cook your tenderloin on the grill. Make sure your grill is hot, and preheat it for about 10-15 minutes. Cook the tenderloin over medium heat for about 10-12 minutes per side, or until it reaches your desired level of doneness.

A hot grill will create beautiful grill marks on the outside, and the tenderloin will cook evenly. It’s like a beautifully illustrated book, with each page perfectly formed! If you're using a gas grill, make sure you're using a meat thermometer to check the internal temperature. It's tricky to tell if the tenderloin is cooked all the way through just by looking at it. A meat thermometer is like a compass - it guides you to the perfect level of doneness.

Pan-Searing

Pan-searing is a great way to achieve a crispy crust on your tenderloin. Heat a heavy-bottomed pan over high heat, add a little oil, and then sear the tenderloin for about 2-3 minutes per side. It's all about that nice brown crust. Think of this as adding a touch of flair to your book cover - it makes it more appealing and enticing.

Once the tenderloin is seared, you can transfer it to the oven to finish cooking. Or, if you're feeling adventurous, you can finish it off on the stovetop in a pan with a little butter and herbs. The possibilities are endless! This is like adding a new chapter to your book - it adds a unique twist and a new dimension to the story.

Part 4: Understanding Levels of Doneness

Medium-Rare (130-135°F)

Medium-rare is the preferred doneness for many people, including myself. The steak has a beautiful pink center, and it's incredibly juicy and tender. This is the classic steak experience. The centre will be quite soft, almost yielding. Think of it as a page in a book that’s waiting to be turned, full of anticipation and excitement.

Medium (140-145°F)

Medium is a good option if you like your steak with a little more pink in the center, but still juicy and tender. The center will be slightly firmer than medium-rare. It's a good all-around choice that most people will enjoy. This is like a well-written book with a balanced plot and characters that are neither too overbearing nor too subtle.

Medium-Well (150-155°F)

Medium-well is a good choice if you want a steak that's cooked a bit more through, but not quite well-done. You'll see a bit of pink in the center, but it will be surrounded by a brown ring. It's a bit firmer than medium. This is like a book that has a strong central theme but also includes some subplots to keep the reader engaged.

Well Done (160°F and Above)

Well-done is for those who like their steak completely cooked through. It will have a brown center, and it will be firm and dry. It's not my favourite, but if that's what you prefer, that's what you prefer! Just make sure you don't overcook it, as it will become tough and rubbery. Think of this as a book that has a very straightforward plot and leaves no room for interpretation.

Part 5: Using a Meat Thermometer for Accuracy

This is the part where I get serious. A meat thermometer is your best friend when it comes to cooking tenderloin. It's the only way to ensure that your steak is cooked to your desired level of doneness.

A meat thermometer is a simple device that measures the internal temperature of your steak. You can find them at most grocery stores or online. Just insert the thermometer into the thickest part of the tenderloin, being careful not to touch any bone.

The temperature should be measured in the centre of the steak, not near the surface. Once the thermometer reaches the desired temperature, it's time to take your tenderloin off the heat. Think of this like checking your GPS to ensure you’re on the right path to deliciousness!

Part 6: Resting the Tenderloin

Once your tenderloin is cooked to the desired level of doneness, don't rush to cut into it. Let it rest for about 10-15 minutes before slicing. Resting allows the juices to redistribute evenly throughout the steak, resulting in a more tender and juicy final product. This is like giving your book a moment to breathe - it allows the story to settle and resonate with you.

The meat will still be warm, but it will be less likely to become dry and tough. It's a simple step that makes a big difference. Just relax, grab a drink, and give it a few minutes. You’ll be glad you did!

Part 7: Slicing and Serving

Finally, it's time to slice and serve your tenderloin. Use a sharp knife to slice the steak against the grain. This will help to ensure that the steak is tender and easy to chew.

Serve your tenderloin with your favourite sides. I love to serve mine with roasted vegetables, mashed potatoes, or a simple salad. A good sauce also goes a long way. Think of this like adding a beautiful illustration to your story - it adds a touch of elegance and complements the overall experience.

Part 8: Serving Size and Leftovers

A tenderloin typically yields about 8-10 servings, depending on the size of the steak. Of course, you can always adjust this based on how much meat you want each person to have. Think of this as the number of chapters in your book - it's a good estimate, but you can always add more or fewer pages as needed.

If you have any leftovers, you can store them in an airtight container in the refrigerator for up to 3-4 days.

Leftover tenderloin can be sliced and added to salads, sandwiches, or even used in a stir-fry. It's a versatile cut of meat that can be used in many different dishes. It’s like a book that can be read multiple times in different ways!

Part 9: Tips and Tricks

Seasoning

There are endless possibilities when it comes to seasoning tenderloin. Salt and pepper are classic choices, but you can also get creative with herbs, spices, and even rubs. This is like adding your own personal touch to your story - you can experiment with different flavors and styles. Just be sure not to over-season the steak, or you'll risk masking its natural flavour.

Don't Overcook

Remember, it's better to undercook than overcook a tenderloin. A slightly undercooked steak can always be cooked a bit more, but once it's overcooked, there's no going back. This is like editing your book - you can always add more words, but you can’t take them away once they’re there.

Use a Meat Thermometer

I cannot stress this enough. A meat thermometer is the only way to ensure that your tenderloin is cooked to the desired level of doneness. It's a small investment that will make a big difference. Think of it as your personal editor for your culinary masterpiece!

Rest the Steak

Let your tenderloin rest for at least 10-15 minutes before slicing. This will allow the juices to redistribute evenly throughout the steak, resulting in a more tender and juicy final product. This is like giving your story a chance to breathe - it allows the flavors to mingle and create a harmonious experience.

Slice Against the Grain

When slicing your tenderloin, slice against the grain. This will help to ensure that the steak is tender and easy to chew. This is like reading a book from left to right - it makes the experience smooth and enjoyable.
