Why Trim Your Own Beef Tenderloin?
Beef tenderloin is one of the most tender and desirable cuts of beef. Buying it whole and trimming it yourself not only saves money but also gives you control over the quality and thickness of your steaks or roast. Plus, you get extra trimmings that can be used for stir-fries, stews, or even homemade beef stock.
What You’ll Need
- Whole beef tenderloin: Sometimes called “PSMO” (Peeled, Side Muscle On), this is the untrimmed version you’ll find at butcher shops or wholesale stores.
- Sharp boning or fillet knife: A flexible, sharp knife is essential for clean cuts.
- Cutting board: Use a sturdy, non-slip board large enough for the tenderloin.
- Paper towels: For blotting and cleaning up as you go.
- Plastic wrap (optional): For easier handling and storage after trimming.
Understanding the Beef Tenderloin
The beef tenderloin runs along the backbone of the cow and is prized for its tenderness. When you buy a whole tenderloin, you’ll notice three main parts:
- Head (large end): The thicker, rounded part often used for Chateaubriand.
- Center-cut (middle): The most uniform section, perfect for filet mignon steaks or an elegant roast.
- Tail (thin end): The tapered end that can be used for smaller steaks or stir-fry strips.
Step-by-Step: How to Trim a Whole Beef Tenderloin
-
1. Unwrap and Pat Dry
Remove the tenderloin from its packaging and pat it dry with paper towels. A dry surface makes trimming much easier and safer.
-
2. Locate the Side Muscle (“Chain”)
The chain is a fatty, loosely attached piece running along one side of the tenderloin. Gently pull it away with your fingers, using your knife to help separate it where needed. Don’t discard it—it’s great for stir-fry or ground beef.
-
3. Remove Excess Fat
Trim off any large, thick pieces of fat from the surface. Use your knife to carefully slide under the fat and lift it away, taking care not to remove too much meat in the process.
-
4. Take Off the Silver Skin
The silver skin is a tough, shiny membrane that won’t break down during cooking. To remove it:
- Slip the tip of your knife just under one end of the silver skin.
- Angle the blade upward and gently slice along the length of the membrane, keeping the blade as close to the silver skin as possible to avoid losing meat.
- Continue until all silver skin is removed.
-
5. Square Off and Portion
If you want to create an even roast or steaks, square off the ends by trimming any ragged bits from the head or tail. You can now cut the center section into steaks (filet mignon) or leave it whole for roasting.
What to Do With Trimmings?
- The chain: Dice for stir-fries or use in chili.
- Fat trimmings: Render for cooking oil or add flavor to stews.
- Silver skin: Discard, as it’s too tough to eat.
- Small meat scraps: Save for kebabs or homemade burgers.
Tenderloin Cooking Tips
- Tie your roast: If roasting the whole tenderloin, use kitchen twine to tie it every couple of inches. This ensures even cooking and a nice shape.
- Season generously: Tenderloin is mild in flavor—don’t be shy with salt, pepper, and your favorite herbs or spices.
- Sear before roasting: For a beautiful crust, sear your trimmed tenderloin in a hot pan before finishing in the oven.
- Use a meat thermometer: For perfect doneness, aim for 125°F–130°F (52°C–54°C) for medium-rare after resting.
Helpful Tips for Trimming Success
- Keep your knife sharp: A sharp blade makes trimming safer and more precise.
- Work slowly: Take your time and make small cuts—rushing can lead to wasted meat.
- Chill the meat slightly: If your tenderloin is very soft, pop it in the freezer for 15–20 minutes before trimming for easier handling.
- Don’t worry about perfection: Home-trimmed tenderloins may not look like those from fancy butchers, but they’ll taste just as delicious!
Frequently Asked Questions (FAQ)
Can I ask my butcher to trim my beef tenderloin?
Absolutely! Most butchers are happy to trim your tenderloin for you. However, doing it yourself saves money and lets you keep all those useful trimmings for other recipes.
What’s the difference between “peeled” and “unpeeled” beef tenderloin?
An “unpeeled” or PSMO tenderloin comes with all fat, silver skin, and chain attached—perfect if you want to save money and trim it yourself. A “peeled” tenderloin has already been cleaned up but costs more per pound and leaves you with fewer trimmings for other uses.
How long does trimmed beef tenderloin last in the fridge?
A trimmed beef tenderloin will keep in the refrigerator for up to three days. For longer storage, wrap tightly in plastic wrap and freeze for up to six months.
Can I use trimmings for anything besides stir-fry?
Certainly! Use meat trimmings for tacos, kebabs, soups, or homemade burgers. Fat trimmings can be rendered down for flavorful cooking oil or added to stews for extra richness.
The Bottom Line
Trimming a whole beef tenderloin at home isn’t just cost-effective—it’s also rewarding. With a sharp knife and a little patience, you’ll have beautifully prepared steaks or roasts and plenty of flavorful trimmings for other dishes. Next time you’re planning a special meal or looking to impress your guests, try trimming your own beef tenderloin—you might never go back to store-trimmed again!
