What Is a Boston Butt?

Boston butt is a cut of pork from the upper shoulder.

It has a lot of fat and tough muscle.

That is a good thing.

When cooked low and slow, the fat melts and the meat turns tender.

This cut is most often used for pulled pork.

It can be smoked, roasted, or cooked on a grill with indirect heat.

Because it is thick and dense, internal temperature matters more than time.

If you want a quick visual reference that breaks this down even further, this detailed resource on The Best Boston Butt Cooking Temperature Chart is a helpful companion to keep bookmarked.

Boston Butt Cooking Temperature Chart

Here is a simple chart you can use during your cook.

Boston Butt Temperature Chart

• Raw pork: below 40°F

• Safe to eat: 145°F

• Stall zone: 150–170°F

• Sliceable pork: 180–185°F

• Pulled pork ready: 195–205°F

• Resting temp drop: minus 5–10°F

This chart is the backbone of cooking Boston butt the right way.

What Each Temperature Range Means

Let’s break down the chart so it makes sense.

Below 40°F: Raw State

This is fridge temperature.

Keep the meat cold until you are ready to cook.

Do not leave it out too long before it goes on the heat.

145°F: Safe but Not Tender

At 145°F, pork is safe to eat.

But Boston butt is not ready here.

The meat will still be tough and chewy.

This temperature matters for food safety, not texture.

150–170°F: The Stall

This range is called “the stall.”

Many cooks panic here.

The temperature seems stuck for hours.

What is happening is moisture evaporating from the meat.

This cools the surface, just like sweat cools skin.

This is normal.

Do not rush it.

Low and slow wins here.

180–185°F: Sliceab

le Pork

At this point, the meat is much softer.

You can slice it, but it will not pull apart easily.

Some people stop here if they want sliced pork instead of pulled pork.

195–205°F: Perfect Pulled Pork

This is the goal for most cooks.

At this range, collagen breaks down fully.

The meat becomes juicy and tender.

When a probe slides in with little resistance, the Boston butt is done.

Best Cooking Temperature for Boston Butt

Most pitmasters cook Boston butt at 225°F to 250°F.

This range allows fat to render slowly.

It also helps smoke flavor soak into the meat.

You can cook hotter, up to 275°F, if needed.

The meat will still be good, but low and slow gives the best texture.

If you are using pellets instead of charcoal or wood chunks, this guide on Cook Pork Shoulder on a Pellet Grill: Time and Temp Guide explains how temperature control works a bit differently on pellet grills.

How Long Does Boston Butt Take to Cook?

Time depends on weight and grill temperature.

A common rule is 1.5 to 2 hours per pound at 225°F.

A 8-pound Boston butt can take 12 to 16 hours.

Always cook by temperature, not by the clock.

Why Resting Matters

Once the meat hits 195–205°F, take it off the heat.

Do not pull it right away.

Let it rest for at least 30 minutes.

One hour is even better.

Resting lets juices move back into the meat.

This makes pulled pork moist and flavorful.

Using a Temperature Guide While Cooking

Watching temperatures all day can get tiring.

Many grillers like having a quick reference nearby.

A meat temperature chart magnet, like the Easy Function Meat Temperature Guide, can be helpful.

It sticks to your smoker or fridge and shows safe and target temperatures at a glance.

It does not replace a thermometer, but it helps you stay on track without guessing.

Common Temperature Mistakes to Avoid

One mistake is pulling the meat too early.

If you stop at 180°F, the pork will not shred well.

Another mistake is cooking too hot at the start.

High heat can dry the outside before the inside is ready.

Also, do not skip resting.

Even perfect temperature pork can lose juice if rushed.

Final Thoughts

Boston butt is forgiving, but temperature control makes all the difference.

Use the cooking temperature chart as your guide.

Stay patient during the stall.

Aim for 195–205°F for pulled pork.

Always rest before shredding.

Once you learn these temperature stages, Boston butt becomes one of the easiest and most rewarding cuts to cook.
