Summer Sausage Internal Temperature

Short answer:

That's the number for summer sausage made with Cure #1 (which it always should be). Cook to 155°F and it's safe, holds its texture, and slices clean. Chase the timer instead of the thermometer and you'll either pull it underdone or blow past the mark and dry it out.

Why 155°F — and why "cured" matters

Plain ground meat has to hit 160°F to be safe. Summer sausage is different: it's cured with Cure #1, and it's cooked low and slow over hours. That combination — cure plus a gradual, sustained heat schedule — makes 155°F the target the craft world uses. Push past 160°F and you start rendering fat out of the sausage ("fat-out"), which leaves it dry and greasy at the same time. 155°F is the line where it's safe and still good.

This only applies to cured summer sausage. If it wasn't made with cure, none of these numbers protect you — and you shouldn't be low-smoking uncured ground meat in the first place. (New to cure? Start with How Much Cure #1 Per Pound of Meat.)

How long does it take to smoke?

Honest answer: it depends — which is exactly why you go by internal temp, not a timer. A 2-inch stick comes up to temp far faster than a 4-inch summer sausage chub. Your smoker, the weather, the humidity, and how full the smoker is all move the clock. Plan on roughly 4 to 8 hours, sometimes more — but the thermometer is the boss.

The smoke schedule (step it up — don't blast it)

You don't smoke summer sausage at one temperature. You step the smoker up gradually so the sausage dries, takes smoke, and cooks evenly without fatting out. This works on any smoker — pellet grill, electric, or a traditional offset — the temperatures are what matter, not the fuel:

1. Dry: ~120–130°F, no smoke, about an hour (vents open if your smoker has them), until the casing is dry to the touch. Smoke won't stick to a wet casing. On a pellet grill, just run it low with the lid cracked or on a smoke setting.
2. Smoke: step up to ~140°F and apply smoke for a few hours.
3. Cook up: step up in ~10°F increments (150°F → 160°F → up to about 170°F smoker temp) until the internal temp reaches 155°F.
4. Never run the smoker much above ~170–180°F — that's the fastest way to fat-out.

Set temp isn't actual temp — watch the chamber

Here's a trap that ruins batches: the number you set on your smoker is not the same as the actual temperature inside it. Pellet smokers especially swing — you set 165°F and the chamber can spike well past 200°F during an auger cycle, or run cold on a windy day. Every smoker has hot and cold spots, and the dial reading is often nowhere near what your sausage is actually sitting in.

That matters because fat-out and overcooking happen based on the real ambient temp, not the setting. If your smoker's set to 170°F but it's actually running 190°F+, you'll blow past your target and dry the batch out — and never know why.

The fix: run a second probe for the chamber. Put an independent thermometer at grate level, right next to the sausage, and trust that number over the dial. One probe in the meat (internal temp), one measuring the air around it (ambient temp). That's how you actually control the cook.

The finish: ice bath (optional but smart)

The second it hits 155°F, an ice-water bath stops the cook instantly and helps set the texture and prevent wrinkling. It's optional — plenty of makers just cool it at room temp and then bloom it in the fridge — but the ice bath gives you a cleaner slice.

The one tool you actually need

A reliable probe thermometer — ideally a leave-in probe you can watch without opening the door. Every time you open the smoker you dump heat and add time. Cheap thermometers lie; get one you trust and put it in the thickest chub.

DeepWoodz Smokehouse has a built-in multi-stage smoke timer — program the step-up schedule once and it walks you through each temperature stage with alerts, so you're not babysitting a notebook. Pair it with a probe and you're dialed.

Bottom line

155°F internal, measured with a probe. Step the smoker up gradually, keep it under ~170°F, and let temperature — not time — tell you when it's done.
