Why Cook Pork Shoulder Low and Slow at 275°F?

Cooking the pork shoulder low and slow is the key to breaking down its tough connective tissues and transforming it into succulent fall-apart meat.

Here are some benefits of roasting pork shoulder in the oven at 275°F:

• Extended cooking tenderizes the meat.
• Low heat prevents drying out the pork.
• Gives time for delicious smoky roast flavor to develop.
• Allows fat to baste the meat and keep it moist.
• Results in pull apart tender meat that shreds easily.
• Gives you flexibility if timing needs to be adjusted.
• More forgiving temperature if oven fluctuates slightly.

The pork shoulder contains a high amount of collagen that must be melted to achieve that fork-tender texture. The lengthy 275°F cooking gives the collagen time to dissolve into delicious gelatin that keeps the meat succulent.

Estimated Cook Times Per Pound at 275°F

A general guideline for roasting pork shoulder at 275°F is to calculate approximately 1 hour and 15 minutes per pound.

So for example, a 5 lb pork shoulder will take roughly 6 hours to reach doneness.

Here are some estimated cook times:

• 3 lb shoulder: 3.75 hours
• 5 lb shoulder: 6 hours
• 7 lb shoulder: 8 hours
• 10 lb shoulder: 12 hours

These times are just estimates. Always use a meat thermometer to check for doneness rather than relying solely on cook times. Pork shoulder can vary quite a bit.

Now let’s get into the step-by-step cooking instructions.

How to Cook Pork Shoulder at 275°F – Step-By-Step

Follow these simple steps for roasting the perfect juicy, fork-tender pork shoulder in the oven at 275°F:

1. Prepare the Pork Shoulder

• Start with a bone-in or boneless pork shoulder roast, 3-10 lbs.
• Trim off any excess fat or skin.
• Pat the pork dry and season all over with a dry rub. Try garlic, salt, pepper, paprika, oregano.
• For extra flavor, inject with a marinade or broth.
• Refrigerate overnight to allow seasonings to penetrate meat.

2. Preheat Oven to 275°F

• Preheat your oven to 275°F. Low and slow is the name of the game.
• A roasting pan with a rack works best to elevate the pork, but a baking dish will also work.
• Pour 1 cup of water, broth, or other liquid in the bottom of the pan.

3. Roast the Pork Shoulder

• Place seasoned pork on prepared pan, fat side up.
• Insert an ovenproof meat thermometer into thickest part, not touching bone.
• Roast at 275°F for approximately 1.25 hours per lb.
• Baste occasionally with pan juices if desired.

4. Wrap and Finish Cooking

• Once internal temp hits 160°F, tent pork with foil to prevent over browning.
• Continue roasting until fork tender and temp reaches 200-205°F.
• Adding broth and closing foil tight at the end helps steam and tenderize.

5. Remove and Rest

• Carefully remove roasting pan from oven when pork reaches 200-205°F.
• Tent pork with foil and let rest for 20-30 minutes.
• This allows juices to redistribute through meat.

6. Serve and Enjoy!

• Slice or shred pork as desired and serve!
• Delicious in tacos, sandwiches, salads, rice bowls, noodles, and more.

Now let’s go over some key tips and pointers for roasting pork shoulder like a pro!

Tips for Moist, Tender Oven-Roasted Pork Shoulder

• Use a thermometer – don’t rely solely on cook times. Cook to 200-205°F.

• Let it rest – Waiting 30 minutes before slicing allows juices to redistribute.

• Reserve juices – Use defatting separator and reserve juices for serving.

• Prevent drying – Baste with juices to keep moist. Tent with foil if browning too fast.

• Shred carefully – Use two forks to gently pull meat into shreds. Avoid overhandling.

• Add seasoning – Flavor with more herbs, spices, sauce once cooked and rested.

• Reheat carefully – Add moisture when reheating leftovers to prevent drying out.

How to Tell When Pork Shoulder is Done

It can be tricky to determine exactly when a pork shoulder roast is done since cook times can vary. Here are some ways to tell when it’s ready:

• Temperature – Use a thermometer to check for 200-205°F in the thickest part.

• Tenderness – Meat should shred and pull apart easily when poked with a fork.

• Bone wiggle – Bone should twist loosely when ready (if bone-in roast).

• Toothpick test – A toothpick should slide in and out of the meat with little resistance.

• Visual test – Look for pork to appear very tender and starting to split at the seams.

Let the internal temperature be your guide overestimated cook times. Pork shoulder can gain tender, juicy perfection anywhere from 195°F all the way up to 210°F.
