Choosing the Right 1 lb Tenderloin

The first step is selecting a high-quality tenderloin that’s about 1 pound in size. Here’s what to look for:

• Weight of 1 lb—A few ounces off is fine, but try to get it as close to 1 lb as you can.

• Uniform shape – Avoid oddly shaped tenderloins with thin or thick parts

• Good marbling – Some fat marbling throughout is desirable for flavor and moisture.

• Minimal trimming – Light silver skin is okay but avoid big pieces of fat/gristle.

• No enhancements – Opt for all-natural over “enhanced” pork injected with broth.

• Pasture-raised – While pricier, pasture-raised pork has superior flavor.

Ask your butcher for a nicely marbled 1 lb tenderloin with minimal trimming. This size is perfect for 2-4 servings.

Prepping a 1 lb Tenderloin for the Oven

To prep pork tenderloin for the oven, just follow these simple steps:

• Pat dry – Use paper towels to remove any excess moisture on the surface.

• Season generously – Coat all sides with about 1⁄2 tsp salt and black pepper.

• Let sit – Allow to rest at room temperature for 15-30 minutes after seasoning.

• Preheat oven – Heat oven to 375°F. Use an oven thermometer to verify temperature.

Proper prep is crucial for even cooking and amazing flavor development when baking. Now it’s time to get this pork in the oven!

Baking Times for a 1 lb Pork Tenderloin

When cooking a 1 lb pork tenderloin, use these baking guidelines:

• Cook at 375°F – This temperature prevents overcooking while still developing flavor.

• Cook for 30-40 minutes – A 1 lb tenderloin takes about 30-40 minutes to bake fully.

• Internal temp of 145°F – Check temperature in thickest part with a meat thermometer.

• Rest 5-10 minutes – Letting it rest allows juices to redistribute.

So for a quick recap, bake at 375°F for around 30-40 minutes until the internal temperature hits 145°F. Rest, then slice and serve!

Using a Meat Thermometer Correctly

Using an instant read thermometer is crucial for perfectly cooked pork. Follow these tips:

• Insert into thickest area – Be sure to get the thermometer into the meatiest part.

• Avoid bone – Temperature will read falsely high if probe touches the bone.

• Check multiple locations – Test a couple areas to confirm even cooking.

• Wait for readout – Digital thermometers take 10-15 seconds to get an accurate temp.

• Clean after use – Be sure to wash thermometer probe after each use.

Investing in a good thermometer ensures your pork cooks to a safe and proper temperature without overcooking. It takes the guesswork out of determining doneness.

Troubleshooting Pork Tenderloin Issues

Here are some common problems and how to avoid them:

Dry, tough meat – Cooked too long. Use a meat thermometer and don’t overbake.

Raw center – Didn’t cook long enough. Increase time and monitor temp.

Uneven cooking – Thicker parts undercooked. Start meat at room temp and tent with foil.

No browning – Wet surface prevents browning. Pat very dry before seasoning.

Curling up – Caused by contractions in muscle fibers. Gently flatten before cooking.

With practice, you’ll know exactly how long to bake a 1 lb pork tenderloin for tender perfection every time. Adjust time and temperature as needed based on your oven.

Seasoning and Flavoring Ideas

While plain salt and pepper is delicious, you can take your baked tenderloin to the next level with these flavor ideas:

• Dry rubs – Coat with spices like garlic powder, onion powder, paprika, oregano, cumin, chili powder, brown sugar, coffee, or citrus zest.

• Wet marinades – Soak pork in marinades made with oil, vinegar, garlic, herbs, soy sauce, wine, fruit juice or mustard overnight.

• Brines – Soak pork in a saltwater brine for enhanced moisture and seasoning.

• Glazes – Brush with sweet glazes made from maple syrup, honey, preserves, mustard, or hoisin sauce during baking.

• Herb paste – Slather pork with an easy blend of fresh herbs, oil, garlic, citrus zest and pepper before cooking.

Feel free to get creative and try out flavor combos until you find favorites!

• Place in an airtight container or resealable plastic bag.
