Herbed Butter Pork Tenderloin Recipe

Dry the pork first—moisture kills the crust, and the crust is basically the whole point. Forty-four minutes total. Twenty-two to prep, twenty-two in the oven and skillet combined. Not complicated. Just needs attention.
Why You’ll Love This Herbed Butter Pork Tenderloin
Done in under 45 minutes. Real dinner, not something that feels rushed.
The dry rub sticks. Garlic powder, Italian seasoning, onion powder—they don’t wash off when you sear it. They actually build a crust that tastes like something.
Butter melts into the meat while it roasts. Not on top of it, into it. Changes everything about the texture.
Looks like you spent time on it. Isn’t hard. People always assume it is.
Works cold the next day. Maybe better cold. Weird but true.
What You Need for Herbed Butter Pork Tenderloin
One pork tenderloin. One to 1.2 pounds. Size matters because it controls your cook time. Thicker cuts need longer.
Olive oil. Not fancy. Just something that won’t burn at medium heat. Avocado oil works too. Butter would scorch.
Garlic powder. Three teaspoons. Not fresh garlic—it burns in the dry rub before the pork even hits the pan. Dried works.
Kosher salt and black pepper. Two teaspoons salt, one of pepper. Coarser salt stays on the meat instead of dissolving into nothing.
Dried Italian seasoning and onion powder. Two teaspoons seasoning, one of onion powder. They don’t add much individually. Together they’re what makes this taste like something instead of just salt-crusted meat.
Butter. Three tablespoons, cut into three pieces. Cold butter. The pieces melt unevenly on top, and that’s intentional—it means some parts get richer than others.
Fresh parsley at the end. Not essential. Changes nothing about the taste. Just makes it look intentional.
How to Make Seared Pork Tenderloin with Herbs
Get your oven to 410. Use actual temperature—don’t guess. Foil the baking sheet. Doesn’t matter if it’s shiny side up or down.
Mix the dry rub in a medium bowl. Garlic powder, salt, pepper, Italian seasoning, onion powder. Stir it once. Takes 30 seconds.
Pat the tenderloin completely dry. Use paper towels. Really dry. Wet pork steams instead of sears, and steaming means no crust. The crust is why you’re making this.
Coat it all over with the rub. Use your fingertips to press it in. Get the ends too. Looks like it’s covered in dirt. That’s right.
Heat olive oil in a heavy skillet over medium. Wait until it shimmers and barely smokes. You’ll see it—the surface gets wavy. That’s when it’s hot enough.
Add the pork. Don’t move it around. Sear each side and both ends. Takes three to four minutes per side. You want dark golden. Not burnt. But close. That’s the Maillard reaction building flavor. If you keep flipping it, it steams instead of searing.
How to Get Herb Crusted Pork Tenderloin Perfectly Roasted
Transfer it straight from the skillet to the foil-lined sheet. Lay the three butter pieces spaced out on top. They should just sit there, not melting yet.
Wrap it loosely in foil. Tent the foil over the top, don’t seal it tight on the sides. You want the butter steam to stay around the meat, but not trap it completely—the air circulation keeps it from getting soggy.
Roast for 18 to 25 minutes. Check the internal temperature at 18 minutes. Use an instant-read thermometer into the thickest part. You’re looking for 143 to 158 degrees. Pork is safe at 145, but you can go higher if you want. Timing varies depending on how thick your tenderloin is. Thinner ones cook faster.
Pull it out. Sprinkle fresh parsley on top if you want it to look like you tried.
Tent it loosely with foil again. Let it rest five minutes. Don’t skip this part. The rest redistributes the juices back into the meat. Skip it and it dries out on your plate.
Slice against the grain. That makes it tender instead of chewy. The grain runs the long way down the tenderloin. Cut perpendicular to it.
Pork Tenderloin Dry Rub Recipe Tips and Common Mistakes
Don’t skip the dry pork step. Honestly. It’s the difference between crust and rubber. Paper towels, not a dish towel.
The skillet needs to be hot enough. If it’s not actually smoking a little, it’s not hot enough. The oil should shimmer and move around. Cold skillet equals no sear.
Don’t crowd the meat in the pan. It’s just one tenderloin. Give it space. Moving it constantly means it steams instead of getting a crust. Set it, look at your phone, flip once.
Garlic butter sounds like the focus but it isn’t. The dry rub is. The butter just melts on top and adds richness. If you tried to make this with fresh herbs instead of dried, they’d burn. Dried herbs are the move here.
The foil wrap keeps things moist. You’re basically creating a steam chamber for the last half of cooking. That’s what makes it stay juicy inside while the outside’s crusty.
Rest the meat. Five minutes. It feels like nothing. It’s everything.

Herbed Butter Pork Tenderloin Recipe
- 1 pork tenderloin (about 1 to 1.2 lbs)
- 1 tbsp olive oil
- 3 tsp garlic powder

- 1 Preheat oven to 410F and prepare a baking sheet with foil; set aside.
- 2 In medium bowl, blend garlic powder, salt, pepper, dried Italian seasoning, onion powder until combined.
- 3 Dry pork tenderloin thoroughly with paper towels; moisture ruins crust.
- 4 Coat tenderloin all around with seasoning blend, rub in deeply with fingertips.
- 5 Heat olive oil in heavy skillet over medium heat until it shimmers and lightly smokes.
- 6 Add seasoned pork; sear each side and ends until dark golden crust forms (about 3-4 min per side). Resist moving too much; you want that Maillard reaction.
- 7 Transfer pork directly to foil-lined sheet. Place three butter chunks spaced evenly on top.
- 8 Wrap pork loosely but sealed in foil, tenting over the top to trap butter melt and steam.
- 9 Roast in oven about 18-25 minutes or until internal temp hits 143-158F. Check at 18 min to avoid overcooking. Use instant read thermometer into thickest part. Timing varies by tenderloin thickness.
- 10 Remove from oven, sprinkle fresh parsley over top for brightness.
- 11 Tent again loosely with foil; rest 5 min to let juices redistribute. Don’t skip resting or pork dries out.
- 12 Slice against grain for tender bites.
Frequently Asked Questions About Pork Tenderloin Dinner
Can you make garlic butter pork tenderloin with fresh herbs instead of dried? No. Fresh herbs burn in the dry rub. Dried is what works here. You could sprinkle fresh on top at the end like the parsley. Doesn’t do much except look nice.
How do you know when the seared pork tenderloin is done cooking? Internal thermometer. Into the thickest part. 143 to 158 degrees. Don’t guess. Undercooked tastes weird. Overcooked is dry. The thermometer takes two seconds.
What if your pork tenderloin is thicker than normal? Add five to ten minutes to the roast time. Check it at 18 minutes anyway. Thickness varies. Some cook in 18 minutes. Others need 25. The thermometer tells you, not the clock.
Can you prep the Italian seasoned pork tenderloin ahead of time? Apply the rub and let it sit in the fridge. Eight hours is fine. Overnight too. Won’t hurt. Sear it cold, it takes a couple minutes longer. Not a problem.
Does pork tenderloin with herbs reheat well? Cold is actually better than reheated. Slice it, eat it cold. Or reheat it gently in a low oven. Don’t microwave it or it dries out completely.
What should you serve with herb crusted pork tenderloin roast? Anything. Vegetables, rice, salad, potatoes. The butter and herbs are rich enough that it doesn’t need much. Green beans work. So does bread to soak up the juices.
