As a busy home cook, I’m always looking for quick and easy dinner solutions that still feel special. Pork tenderloin is one of my go-to proteins because it cooks up so fast and takes well to a variety of flavor profiles. But I used to struggle with knowing exactly how long to cook pork tenderloin to achieve the ideal texture – juicy, tender and just a hint of pink
Through trial and error in my kitchen, I’ve honed my method so I can now whip up a perfect 1-2 lb pork tenderloin in under 30 minutes. Keep reading for my complete guide to cooking times, temperatures, prep tips and serving ideas so you can master this versatile, lean cut of pork.
Choosing the Right Size Tenderloin
For a dinner for two or three people, a 1-2 lb pork tenderloin is the perfect size. Anything larger may be overkill unless you’re feeding a big crowd. Here’s a simple guideline for choosing the right tenderloin weight:
- 1 lb feeds 2-3 people
- 1.5 lbs feeds 3-4 people
- 2 lbs feeds 4-6 people
When purchasing pork tenderloin, look for pieces that are evenly sized throughout, with minimal tapering on the ends. Avoid any with large pockets of fat or sinew. The uniform shape will allow for even cooking.
Prepping the Tenderloin
Proper seasoning and prep is key to maximizing the flavor of lean pork tenderloin, Here are my tips
- Trim excess fat & silver skin: Use a sharp knife to remove the shiny silver membrane.
- Season all over: Coat with oil, salt, pepper and any other spices.
- Allow to rest: Let sit at room temperature for 30 minutes before cooking.
You can also marinate the pork for added moisture and flavor. A simple marinade of oil, acid like lemon juice or vinegar, and herbs does the trick.
Choosing a Cooking Method
Pork tenderloin lends itself well to a variety of cooking methods. These are my favorites:
Pan Searing
This quick stovetop method leaves you with a sear-crusted exterior and tender, juicy interior.
- Heat oil in a skillet over medium-high heat.
- Cook tenderloin 2-3 minutes per side until browned.
- Finish in a 400°F oven until internal temp reaches 145°F.
Roasting
Roasting in the oven delivers evenly cooked, juicy pork in under 30 minutes.
- Preheat oven to 400°F.
- Heat oil in oven-safe pan. Sear pork 2-3 minutes per side.
- Roast in pan 15-20 minutes until internal temp reaches 145°F.
Grilling
The grill adds delicious smoky flavor. Use medium-high heat.
- Sear over direct heat 1-2 minutes per side.
- Move to indirect heat and grill 10-15 minutes until 145°F internal temp.
Calculating Cook Times
The cooking time can vary slightly depending on size and shape, but use these guidelines:
- 1 lb tenderloin:
- Pan searing: 8-10 minutes total
- Oven: 15-20 minutes at 400°F
- Grill: 12-15 minutes
- 1.5 lb tenderloin:
- Pan searing: 10-12 minutes
- Oven: 20-25 minutes at 400°F
- Grill: 15-18 minutes
- 2 lb tenderloin:
- Pan searing: 12-15 minutes
- Oven: 25-30 minutes at 400°F
- Grill: 18-22 minutes
Always rely on an instant-read thermometer rather than time. The pork is done when it registers 145°F internally.
Resting & Slicing the Pork
After cooking, it’s crucial to let the pork rest for 5-10 minutes. This allows juices to redistribute for tender, juicy meat.
To slice, use a sharp knife to cut the tenderloin crosswise into medallions about 1/2 inch thick. Be sure to slice across the grain of the meat to prevent toughening.
Adding Flavor
While pork tenderloin tastes great simply seasoned with salt and pepper, it also pairs well with a variety of flavors. Consider:
- Fresh herbs like rosemary, thyme and sage
- Spice rubs with chili powder, cumin, paprika
- Sauces like chimichurri, garlic aioli or mustard glaze
- Compound butters for richness
- Marinades for added moisture and flavor
Side Dishes & Serving Suggestions
The beauty of pork tenderloin is that it goes with endless side dish options. Here are some of my favorites:
- Roasted vegetables – potatoes, broccoli, Brussels sprouts
- Green salad, grains or pasta salad
- Buttery mashed or roasted potatoes
- Rice pilaf or risotto
- Fresh bread to soak up juices
Pork tenderloin also shines in dishes like fajitas, tacos, sandwiches, flatbreads and more. Slice and add to pasta, soups or salads for easy weeknight meals.
With this complete guide, you’ll be able to prepare pork tenderloin perfectly timed and seasoned to your taste every time. The quick cook time makes it ideal for hectic weeknights, while the elegant presentation makes it worthy of dinner parties too.

Can I eat pork tenderloin while it’s still a little pink?
Yes, when cooked to the proper internal temperature, pork will still have a hint of pink inside while being fully cooked and safe to eat. The color is not an indicator of doneness. Always use a meat thermometer.
What is the best way to reheat leftover pork tenderloin?
