Follow this complete guide to learn exactly how long to cook a 17 lb pork loin roast in the oven along with tips for the perfect juicy texture

Calculating Cooking Time for a 1.7 lb Pork Loin

The general guideline for calculating pork loin cooking time is:

• 20-25 minutes per 1 lb of meat at 350°F

So for a 1,7 lb pork loin

• 1.7 lbs x 25 minutes per lb = 42.5 minutes
• Round up to 50 minutes for a 1.7 lb pork loin

However, cooking time can vary a bit depending on:

• Oven temperature (higher temp = faster cooking)
• Whether roast is bone-in or boneless (boneless cooks faster)
• Desired doneness (145°F for pink, 160°F for well-done)

To account for these factors, it’s best to calculate a range. For a 1. 7 lb pork loin, the cooking time will be:

• Minimum: 45-50 minutes
• Maximum: 55-60 minutes

Always trust an instant read meat thermometer to tell you the right temperature, not just the time.

Step-by-Step Instructions for a Perfect Pork Loin

Follow these simple steps for foolproof oven roasted pork loin:

1. Prepare the Roast

• Pat 1.7 lb pork loin dry with paper towels
• Trim off any excess fat or silver skin
• Generously season all over with salt, pepper and herbs
• Let sit at room temperature 30 minutes while oven preheats

2. Preheat Oven

• Preheat oven to 350°F
• Use a meat thermometer for accuracy

3. Cook the Pork Loin

• Place seasoned pork loin on a rack in a roasting pan
• Insert meat thermometer into thickest part, not touching bone
• Roast for 50-60 minutes until thermometer reads 140°F

4. Rest and Finish

• Remove roast when internal temp hits 140°F
• Tent loosely with foil and let rest 15 minutes
• Temperature will rise to safe 145°F as it rests

5. Slice and Serve

• After resting, slice pork loin into 1/2 inch slices
• Serve warm with your favorite sides

Inserting the Meat Thermometer Correctly

To get an accurate reading, insert the instant read thermometer into the thickest part of the pork loin, making sure not to hit the bone.

Aim to push the thermometer into the very center of the roast at about a 45 degree angle. For a 1.7 lb pork loin, the thermometer should go in about 1 inch deep.

Double check a few spots to confirm the pork loin is evenly cooked throughout. It should register at least 140-145°F before resting.

Determining Doneness of Pork Loin

Here are signs your pork loin roast is fully cooked when using an instant read thermometer:

• 140-145°F = Slightly pink, juicy interior

• 150-155°F = Trace of pink, firm texture

• 160°F+ = Well done, dry white center

The USDA recommends cooking pork to 145°F minimum for food safety. Letting the pork rest will raise the temp another 5 degrees to land at a safe 150°F after resting.

For best texture and moisture, cook for the lower range of 140-145°F. If you prefer pork more well-done, aim for 155-160°F internal temp.

Maintaining Juiciness

To keep a 1.7 lb pork loin roast as juicy as possible:

• Cook at lower 325°F oven temp
• Baste with pan juices every 20 minutes
• Lightly tent with foil if browning too fast
• Allow meat to rest before slicing

The resting period is key for retaining moisture. As the proteins relax, the juices redistribute through the meat instead of spilling out when cut.

Serving Suggestions

A 1.7 lb pork loin will serve about 4-6 people depending on portions. Pair it with:

• Herb roasted potatoes
• Sauteed green beans
• Salad with vinaigrette
• Fresh baked rolls

Slice the rested pork loin into 1/2 inch slices and serve while still warm. Leftovers will keep refrigerated for 3-4 days. Reheat gently in the microwave or oven until warmed through.

With this handy guide, you now know exactly how long to cook a 1.7 lb pork loin roast in the oven for flawless, juicy results every time. Follow the simple steps and use a meat thermometer for perfect doneness. Enjoy your savory oven-roasted pork loin meal!
