Recipe Overview

Prep Time: 10 minutes
Cook Time: 45 minutes
Total Time: 55 minutes
Servings: 4-5
Yield: 1 pork tenderloin
Dietary Type: Gluten-Free (verify seasoning packet for gluten content)

Ingredients

This recipe relies on a few key components to deliver a wonderfully seasoned and tender pork tenderloin.

1 (1.5-2 lb) boneless pork tenderloin (I usually buy the pre-packaged ones by Hormel or Tyson.)
1-2 packets McCormick’s Bag-N-Season seasoning, for pork tenderloin (depending on how much seasoning you prefer)
1-2 cup olive oil (I just have mine in a big squirt bottle and squirt it as I need it)

Equipment Needed

Cutting board
Fork
Basting brush
Oven-safe baking dish or roasting pan
Aluminum foil or the provided Bag-N-Season bag

Instructions

Crafting this flavorful pork tenderloin is remarkably straightforward, proving that simplicity often yields the most delicious results. Follow these steps for a perfectly cooked and seasoned roast:

Begin by washing the pork tenderloin under cool running water. Gently pat it dry thoroughly with paper towels. This step is crucial for ensuring the seasoning adheres well to the meat.
Lay the dried pork tenderloin on your cutting board. Using a fork, pierce the surface of the tenderloin all over. This allows the seasoning and oil to penetrate the meat, infusing it with flavor. Aim for evenly distributed pricks across the entire surface.
Drizzle a portion of the olive oil directly onto the pork tenderloin. Use your hands or the basting brush to rub it evenly into the surface, coating all sides.
Now, it’s time for the flavor! Sprinkle, a little at a time, the McCormick’s Bag-N-Season mixture onto the pork tenderloin. Continue to sprinkle and rub, working it into the surface of the meat.
Using a basting brush, coat all surfaces of the tenderloin with the oil and seasoning mixture. You’re aiming to create a somewhat of a paste-like consistency, ensuring a good layer of seasoning adheres to the meat.
As you work the seasoning into the pork, add more olive oil as needed. The goal is to create a cohesive coating that will crisp and brown beautifully in the oven.
If using the Bag-N-Season product, carefully place the seasoned tenderloin into the provided bag. Secure the end of the bag according to the package instructions. If you are not using the Bag-N-Season system and are baking directly in a dish, ensure your dish is greased or lined with parchment paper.
If using the bag, pierce the bag in a few places with the fork or a knife to allow steam to escape during baking. This helps to prevent the bag from bursting and ensures even cooking.
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius).
Carefully place the bagged or un-bagged pork tenderloin into an oven-safe baking dish or roasting pan.
Bake in the preheated oven for 45 minutes, or until the internal temperature of the pork reaches 145 degrees Fahrenheit (63 degrees Celsius) when measured with a meat thermometer inserted into the thickest part of the tenderloin. For a more thoroughly cooked, but potentially drier, result, you can bake until 150-155°F (65-68°C).
Once cooked, remove the pork tenderloin from the oven. If it was in a bag, carefully remove it from the bag. Tent loosely with aluminum foil and allow it to rest for 10 minutes before slicing. This resting period is crucial for allowing the juices to redistribute, resulting in a more tender and moist final product.

Expert Tips & Tricks

To elevate your oven-baked pork tenderloin from good to exceptional, consider these chef-inspired insights:

Don’t Fear the Fat: While pork tenderloin is lean, the olive oil is essential for creating a flavorful crust and preventing dryness. Don’t be shy with it, especially when building that seasoning paste.
Temperature is Key: The internal temperature is your best guide for perfectly cooked pork. A meat thermometer is an indispensable tool for this. Remember that the temperature will continue to rise a few degrees as the pork rests.
Resting is Non-Negotiable: I cannot stress this enough – rest your pork! Skipping this step is the most common culprit for dry, tough pork. The juices need time to settle back into the meat fibers.
Seasoning Variations: While McCormick’s Bag-N-Season is a fantastic shortcut, feel free to experiment with your own herb and spice blends. Think garlic powder, onion powder, paprika, thyme, rosemary, and a pinch of cayenne for a little kick.
Achieving a Sear (Optional): For an even more restaurant-quality finish, you can briefly sear the seasoned tenderloin in a hot skillet with a little oil on all sides before baking. This adds another layer of flavor and texture.

Serving & Storage Suggestions

This Oven-Baked Pork Tenderloin is incredibly versatile and pairs beautifully with a wide array of accompaniments.

Serving:
Slice the rested pork tenderloin into medallions about ½-inch thick. It’s delicious served with a side of roasted vegetables like broccoli or asparagus, creamy mashed potatoes, or a fresh garden salad. A drizzle of the pan juices (if any accumulate in the baking dish) can add an extra touch of flavor. For a slightly more elegant presentation, consider serving with a simple pan sauce made by deglazing the baking dish with a splash of wine or broth and reducing it with a knob of butter.

Storage:
Leftover pork tenderloin can be stored in an airtight container in the refrigerator for up to 3-4 days. It reheats well, either gently in a skillet with a little extra liquid (broth or water) to prevent drying, or in a moderate oven. For longer storage, wrap cooled portions tightly in plastic wrap and then aluminum foil, and freeze for up to 2-3 months. Thaw frozen pork in the refrigerator overnight before reheating.

FAQs

Q: Can I prepare this pork tenderloin ahead of time?
A: Yes, you can season the pork tenderloin up to a few hours in advance and refrigerate it. Ensure it comes back to room temperature for about 30 minutes before baking for more even cooking.

Q: Why is my pork tenderloin dry?
A: The most common reasons for dry pork tenderloin are overcooking or not allowing it to rest. Always use a meat thermometer to ensure you’re not cooking it past the recommended internal temperature and be sure to let it rest for at least 10 minutes after baking.

Q: What kind of pork tenderloin should I buy?
A: Look for a tenderloin that is uniform in thickness for even cooking. The pre-packaged ones from brands like Hormel or Tyson are convenient and usually of good quality.

Q: How do I know if the pork is cooked through?
A: The most accurate way is to use an instant-read meat thermometer inserted into the thickest part of the tenderloin. It should register 145°F (63°C) for medium-rare to medium.
