Quick Answer
Smoked mac and cheese isn’t a single-temperature cook the way most pellet-grill side dishes are — Traeger and Z Grills, two competing pellet brands, both split it into a low-temperature smoke-infusion phase followed by a separate high-temperature finish. Traeger smokes its cheese sauce at 180°F for 30 minutes, then bakes the fully assembled dish at 350°F for another 30 minutes. Z Grills goes lower and longer: Super Smoke around 160°F for 90 minutes, then a 15-minute topping/browning phase. Wood choice follows the same split — hickory for Traeger’s short smoke, milder cherry for Z Grills’ long one. Skip either the low-temp smoke stage or the high-temp finish and you either get flat cheese sauce with no crust, or a browned top with barely any smoke flavor underneath.
Smoked mac and cheese at a glance
| Recipe | Smoke stage | Finish stage | Total time | Pellets |
|---|---|---|---|---|
| Traeger (official) | 180°F, 30 min (sauce only) | 350°F, 30 min (assembled, baked) | ~1 hour | Hickory |
| Z Grills (official) | Super Smoke ~160°F, 90 min (assembled) | ~350°F+, 15 min (topping/browning) | ~2 hr 15 min | Cherry |
Neither brand treats this as a set-it-and-forget-it single-temperature smoke — both build in a distinct low-temp phase for smoke and a separate high-temp phase to finish the texture and top.
Step 1: Decide whether to smoke the sauce or the whole dish
Traeger’s method smokes the cheese sauce by itself at a low 180°F before it ever meets the pasta — that gives you full control over exactly how much smoke gets absorbed before you assemble and bake. Z Grills’ method skips that separation and smokes the fully assembled casserole from the start, which is simpler (one less dish and step) but pulls smoke through the pasta and toppings too, not just the cheese.
Neither is wrong; they’re different trade-offs. If this is your first attempt, assembling first and smoking the whole pan (the Z Grills approach) is the easier path with fewer steps to manage.
Cast-iron skillet or deep casserole dish
- A rigid, oven-safe vessel handles both the low-temp smoke phase and the high-temp bake without swapping dishes.
- Cast iron holds heat well after you pull it, so the top stays hot through serving.

Step 2: Match your pellets to your cook length
Traeger’s recipe calls for hickory specifically because its smoke phase is short — only 30 minutes — so a milder wood wouldn’t have time to register against the cheese. Z Grills runs the opposite way: a 90-minute low-temp smoke calls for a milder wood like cherry, since a long exposure to a bold wood like hickory can tip into bitter rather than just smoky.
The rule that falls out of both recipes: short and hot, go bold (hickory); long and low, go mild (cherry, apple, or pecan).

Step 3: Don’t skip the high-temperature finish
This is the step recipes that only give you “smoke at 225°F for an hour” tend to leave out entirely, and it’s why some home cooks end up with pale, loose mac and cheese despite following a temperature and time to the letter. Both Traeger and Z Grills bump the temperature up — to roughly 350°F or higher — for a final 15-30 minutes after the smoke phase, specifically to set the sauce’s texture and brown a breadcrumb or panko topping.
A low, smoke-infusion temperature alone will melt and flavor the cheese, but it won’t brown a crust. If you want that top, budget the extra time and heat; if you’re fine with a looser, unbrowned dish, you can stop after the smoke phase.
Step 4: Cheese and wood, not a delicate blend
Both cited recipes lean toward sharper, meltier cheeses — cheddar as a base in Traeger’s version, a jack/cheddar/gouda blend in Z Grills’ — rather than delicate cheeses. Traeger’s own guidance specifically calls out avoiding stronger, more distinctive cheeses like Swiss, which compete with the smoke instead of carrying it.
Grate your own cheese rather than buying pre-shredded — pre-shredded cheese is coated in anti-caking starch that keeps a smoked sauce from turning fully silky.
Smoked mac and cheese, by the numbers
| Metric | Figure | Source |
|---|---|---|
| Smoke-phase temperature (Traeger) | 180°F, 30 min (sauce only) | Traeger |
| Finish-phase temperature (Traeger) | 350°F, 30 min (assembled) | Traeger |
| Smoke-phase temperature (Z Grills) | Super Smoke, ~160°F, 90 min | Z Grills |
| Recommended pellet (short smoke) | Hickory | Traeger |
| Recommended pellet (long smoke) | Cherry | Z Grills |
Common mistakes
- Treating it as one fixed temperature. Both cited brand recipes split the cook into a low-temp smoke phase and a separate high-temp finish — a single set-and-forget temperature gets you either flat sauce or no crust.
- Bold wood on a long, low smoke. Hickory works for Traeger’s quick 30-minute smoke; on Z Grills’ 90-minute low-temp cook, the same wood can turn bitter. Go milder (cherry, apple, pecan) the longer the smoke phase runs.
- Pre-shredded cheese. The anti-caking starch coating keeps a smoked sauce from going fully silky — grate your own.
- Skipping the finish phase to save time. You’ll end up with well-smoked but pale, loose mac and cheese with no browned top.
- A delicate cheese like Swiss. It gets out-competed by the smoke instead of carrying it — stick to cheddar-forward blends like both cited recipes use.
