  1. Plan Your Menu: Which side dishes are you adding to the pork? These will determine how you season the meat. Don't worry, I've got lots of ideas for you below.

Best Seasonings for Pork Tenderloin

The photo collage shows several different seasoning blends to use for pork tenderloins.

I use cooked pork tenderloin in so many different recipes for my family, I love to season it to match the final meal.

I start by picking my side dishes and then choose the spice blend that pairs the best.

I think the best seasonings for pork tenderloin include:

1. Basic Pork Tenderloin Seasoning:

I use 50-50 mix of Back of the Yards and Gateway to the North because a quick sprinkle of each and my pork is ready to cook with less than a minute of prep.

This tasty blend will match almost any side dish you plan to make.

You could mix your own dry rub by using:

  • Kosher Salt & Black Pepper
  • Garlic Salt
  • Onion Salt
  • Brown Sugar
  • Maple Sugar

2. All-Purpose Pork Seasoning:

Sprinkle dried thyme, garlic salt, and crushed red pepper flakes with a bit of kosher salt and black pepper over the pork.

This classic blend will pair with most dinner options and will have just a pinch of heat.

3. Ethnic Spice Blends for Pork:

I always keep a blackening seasoning or Cajun blend in my pantry, they go perfectly on pork. You could make a pork sandwich with remoulade sauce.

Mediterranean herbs or Greek seasoning let you do a pork tenderloin pita wrap with tzatziki sauce.

Italian herbs are great if you want to pair the pork with roasted primavera veggies.

The photo shows 3 jars of boutique spices for pork.

I also keep a few specialty spices in my pantry from Spiceology.

The maple bourbon seasoning paired with a bit of kosher salt and pepper is one of our very favorites and tastes great when I pair the pork with a sweet potato mash.

The smoky honey habanero is good for a sweet-spicy pork and tastes great with roasted mini potatoes and onions.

I use the Maui Wowee when I want to pair the pork with my roasted peppers and pineapple.

Best Marinades for Pork Tenderloin

When I have a little more time to plan ahead, I make a quick marinade for the pork tenderloins.

My favorite is this easy asian marinade which I use when I want to serve jasmine rice and roasted broccoli. It features soy sauce and brown sugar which both taste great on pork.

Both my zesty Cuban mojo marinade and my Dijon mustard marinade include citrus in the form of oranges, limes, or lemons. The acidity of the citrus brings so much more flavor to the plain pork.

I use the Cuban mojo when I want to make pork tortilla wraps and the Dijon mustard when I want to make sandwiches or pair it with potatoes.

Prep the Pork

Place the pork tenderloins in a large mixing bowl.

Drizzle the olive oil over the top and turn the pork to coat.

Then sprinkle the dry rub over the top. See how easy??

If you're using a marinade, simply pour it over the plain pork and turn to coat. Let it rest for at least 30 minutes or up to 24 hours in the fridge.

The pork has been added to a mixing bowl to be coated with olive oil and sprinkled with seasonings.

Roasted Pork Tenderloin Cooking Instructions

Roasting pork in the oven is my favorite way to finish the pork tenderloins.

You can use a baking dish or a baking sheet if you plan to make a pan meal with roasted veggies on the side.

I prefer using a baking dish when I used a liquid marinade, but it's handy with a dry rub, too.

The pork tenderloins have been added to a white baking dish and are about to go in the oven.

Preheat the oven to 425°F.

Pop the pork into the oven, there's no need to wait till it comes to room temperature first.

Roast the pork for 30 - 40 minutes or until they register 145°F at the thickest part of the meat with an instant-read thermometer.

I always turn my pork tenderloins over half way through the baking time so they brown properly on both sides.

The pork tenderloins now have crispy golden edges from being roasted in the oven.

How to Know the Pork is Done

The easy way to know the pork is finished roasting is to check that it has a safe internal temperature.

I always use a probe thermometer and test the thickest part of the meat.

The safe temp is 145°F but my family prefers the pork to be cooked a little bit longer. I usually pull it from the oven when it registers 160°F.

Air Fryer Cooking Instructions

I usually use my air fryer to make delicious side dishes to go with my pork like my air fryer green beans.

But you can actually cook the pork tenderloins in the air fryer if you prefer that over the oven.

Simply preheat the air fryer to 400°F.

Cook the pork for 30 minutes or until it is safely cooked to 145°F when tested at the thickest part of the meat.

Definitely plan to turn the tenderloins half way through baking so they brown on both sides.

Slow Cooker Cooking Instructions

Using a Crockpot to cook your pork tenderloin is a great option if you'll be out of the house all day and want to come home to a ready-to-eat dinner.

The cooking process naturally will make a tender pork but you will miss out on the crispy golden brown color the oven or air fryer give to the meat.

If that matters to you, you could sear the outside of the pork tenderloins in a skillet with a tablespoon of olive oil over medium high heat.

Brown the pork for 3 - 4 minutes per side and then add it to the slowcooker to finish cooking.

If you don't want that extra step, plan to cook the seasoned pork for 2 hours on low or 4 hours on high or until the pork reads 145°F at the thickest part of the meat.

Variations

While the methods I just mentioned are the basic ways to cook a Smithfield pork tenderloin, you don't have to stop just there.

I've used Smithfield pork in each of the following tasty recipes, too:

What to Serve with Pork Tenderloin

The pork tenderloins are roasted and now served on a white platter with fresh rosemary for garnish.

Roasted pork tenderloins make such an easy dinner protein at the end of the day.

I mix and match it with countless recipes from my site but here are a few favorites to get you started:

Pork goes perfectly with baby potatoes or sweet potatoes of all kinds. Whether you roast them, mash them, turn them into a potato casserole, pork is the perfect pick.

Roasted vegetables like green beans, broccoli, bell peppers, roasted carrots are all fantastic veggies to add to the plate with pork. My air fried butternut squash tossed with fresh sage would be an especially great choice for a pork side dish.

You can make a pork sandwich using a variety of sauces and condiments. My chow chow relish would be my top pick but so would caramelized onions and mustard or spicy sauce for sandwiches.

How to Use Leftover Pork Tenderloin the Next Day

Since a pack of Smithfield pork tenderloins includes two loins, I always bake both of them at one time but plan to use just one for dinner tonight and the second one for another dinner later.

There are so many delicious meals you can make from leftover pork but the most popular one on my site is my mom's Saucy Pork and Noodle Bake. This recipe is perfect for one leftover pork tenderloin.

You can also make my yummy Cuban sliders with leftover pork and pair it with some deli ham, pickles, and cheese or my roasted pork sandwich with caramelized onions.
