- Reliable result for dinner parties or weeknights.
Step-by-step overview
You’ll pat and season the pork, roast it at 400°F (200°C), check the internal temperature, then let it rest before slicing. The whole process is: prep (5–10 minutes), bake (25–30 minutes), rest (5–10 minutes). Have a meat thermometer handy—the meat is done when it reaches 145°F (63°C), which gives a slightly pink, juicy center.
What you’ll need
- 1 pork tenderloin (about 1 to 1.25 pounds)
- 2 tablespoons olive oil
- 2 teaspoons garlic powder
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- Salt and pepper to taste
- Fresh herbs (optional, for garnish)
Ingredient notes and swaps:
- Olive oil can be substituted with avocado oil or melted butter for a richer crust.
- Smoked paprika adds depth; use sweet paprika if you prefer milder flavor.
- If you like more garlic punch, swap garlic powder for 2 cloves minced garlic and rub it on before roasting.
Step-by-step instructions
- Preheat oven to 400°F (200°C).
- Pat the pork dry with paper towels to help the rub adhere and promote browning.
- In a small bowl, whisk together olive oil, garlic powder, onion powder, smoked paprika, salt, and pepper until combined.
- Rub the mixture evenly all over the tenderloin, coating every side.
- Place the seasoned tenderloin in a baking dish or on a rimmed sheet pan.
- Roast in the preheated oven for 25–30 minutes. Use an instant-read thermometer inserted into the thickest part—the target internal temperature is 145°F (63°C).
- Remove from oven and let rest 5–10 minutes before slicing. Resting lets juices redistribute so slices stay moist.
- Slice into medallions and garnish with chopped fresh herbs if desired.
Quick safety note: the USDA recommends a minimum internal temperature of 145°F followed by a 3-minute rest for pork; this recipe follows that guidance for both safety and best texture.
Best ways to enjoy it
Slice the pork thin and serve over creamy mashed potatoes, roasted root vegetables, or a lemony arugula salad. For a light weeknight combo, serve with steamed green beans and quick couscous. If you want a complete seafood-and-pork menu rotation, consider pairing this meal style with a contrasting baked fish like Baked Cajun Salmon with Avocado-Lime Sauce for another oven-friendly main.
Plating tips:
- Fan the medallions on a warm plate; spoon pan juices or a quick mustard pan sauce over the top.
- Garnish with chopped parsley or thyme for color and fresh aroma.
Storage and reheating tips
Refrigeration:
- Store cooled, sliced or whole, in an airtight container for 3–4 days.
Freezing: - Wrap tightly in plastic wrap and foil or use a freezer bag; freeze up to 3 months. Thaw in the refrigerator overnight.
Reheating: - Reheat gently to avoid drying: warm slices in a skillet with a splash of broth over medium-low heat, or reheat whole/halves in a 300°F (150°C) oven until warmed through.
Food safety reminder: discard refrigerated pork after 4 days and never refreeze meat that has fully thawed at room temperature.
Pro chef tips
- Bring the tenderloin to room temperature for 20–30 minutes before roasting for more even cooking.
- Pat the meat dry—moisture is the enemy of a good crust.
- For an extra flavorful crust, quickly sear the tenderloin in a hot skillet (1–2 minutes per side) before transferring to the oven.
- Use an instant-read thermometer and check temperature in the thickest part to avoid overcooking.
- Let the meat rest uncovered on a cutting board; tenting with foil can trap steam and soften the crust.
Creative twists
- Herb-crust: Mix chopped rosemary and thyme into the rub for a Mediterranean spin.
- Honey-mustard glaze: Brush a thin layer of honey-mustard over the tenderloin during the last 5 minutes of roasting for a glossy finish.
- Smoky-sweet: Add 1 teaspoon brown sugar to the rub for a caramelized edge.
- Low-carb: Skip starchy sides; serve over a bed of sautéed spinach and cauliflower mash.
- For paleo: Use coconut aminos instead of salt-based sauces if making a glaze.
Common questions
Q: How long will this take from start to finish?
A: Plan 35–45 minutes total: 5–10 minutes prep, 25–30 minutes baking, and 5–10 minutes resting.
Q: How do I know the pork is done without a thermometer?
A: A thermometer is best. Without one, check for slight springiness and a faint blush of pink in the center when sliced—though this is less precise and not recommended for safety.
Q: Can I marinate this tenderloin overnight?
A: Yes. A simple marinade (olive oil, a splash of acid like lemon or vinegar, and seasonings) can add flavor. Pat dry before applying the rub so the crust still forms.
Q: Can I cook pork tenderloin in an air fryer?
A: Yes—air fryer times vary by model. Cook at 400°F for approximately 18–22 minutes, flipping halfway, and still aim for 145°F internal temperature.
Q: Will the pork be dry if it reaches 145°F?
A: No—145°F gives a slightly pink, tender center. Overcooking past 155–160°F is what tends to dry pork out.
Q: Can I use this method with pork loin instead of tenderloin?
A: Pork loin is larger and thicker; it will need longer roasting time and benefits from lower oven temps for even cooking. Adjust timing and use a thermometer.
