Quick Answer

Sear Costco pork tenderloin briefly, then roast on a sheet pan at 425°F over carrots and parsnips with a honey-mustard glaze until 145°F internal — about 25 minutes. Lean and fast; ready in 40 minutes for 4.

Pork tenderloin is one of Costco's best meat values — lean, quick-cooking, and consistently tender. Costco sells them two to a pack at a price that makes each meal remarkably affordable. This sheet pan recipe roasts the tenderloin alongside potatoes and green beans in a single pan, finished with a honey-mustard glaze that caramelizes in the oven. Dinner in 40 minutes, one pan to wash.

Instructions

  1. 1

    Preheat oven to 425°F. Line a large sheet pan with foil.

  2. 2

    Toss baby potatoes with 1.5 tablespoons olive oil, salt, pepper, and thyme. Spread on one side of the sheet pan. Roast 10 minutes while you prepare everything else.

  3. 3

    Mix Dijon, honey, garlic, rosemary, and remaining olive oil to make the glaze.

  4. 4

    Remove silver skin from the tenderloin by sliding a knife under the shiny membrane and pulling it off. Season with salt and pepper.

  5. 5

    Push potatoes to the sides. Place pork in the center and brush generously with half the glaze. Add green beans to the pan and toss with remaining olive oil and a pinch of salt.

  6. 6

    Roast 20–22 minutes until an instant-read thermometer reads 140°F in the thickest part of the pork. Brush with remaining glaze halfway through.

  7. 7

    Rest pork 5 minutes before slicing. Serve with pan vegetables.

Frequently Asked Questions

What temperature should pork tenderloin be cooked to?+
The USDA recommends 145°F internal temperature for pork, followed by a 3-minute rest. Pull the tenderloin from the oven at 140°F — it will carry over to 145°F while resting. At this temperature, the pork is still slightly pink in the center, which is safe and gives the juiciest result.
What is the silver skin on pork tenderloin and why remove it?+
The silver skin is a tough, silvery connective tissue on the surface of pork tenderloin. Unlike fat, it doesn't render or soften during cooking — it shrinks and can make the tenderloin bow or curl. Remove it by sliding a sharp knife under it at one end and pulling it off in strips before seasoning.
Can I use the second Costco pork tenderloin for this recipe?+
Yes — double everything and use two sheet pans. Or freeze the second tenderloin for later (it freezes beautifully for up to 6 months). Thaw overnight in the fridge before cooking. Pork tenderloin is one of the best proteins to keep in the freezer for fast weeknight meals.
How do I prevent the pork tenderloin from drying out?+
Two things: don't overcook it (use a thermometer and pull at 140°F), and let it rest. Resting allows the juices to redistribute throughout the meat. Glazing with honey-mustard also helps, as the sugars create a protective crust. Brining for 2 hours (salt + water) before cooking gives extra insurance.
What vegetables work best for a pork tenderloin sheet pan dinner?+
Root vegetables and hearty greens that can withstand 20–25 minutes at 425°F: baby potatoes, Brussels sprouts, asparagus, broccoli florets, sliced bell peppers, or sweet potato chunks. Add delicate vegetables like cherry tomatoes or zucchini in the last 10 minutes so they don't become mushy.
