How long does it take to smoke a meatloaf: about three hours at 250°F for a two-and-a-half-pound free-form loaf, off at 160°F internal. Glaze in the last 30 to 40 minutes only, in two thin coats, and rest it fifteen minutes before it is cut.
How long does it take to smoke a meatloaf?
About three hours at 250°F, off at 160°F internal. That is for a two-and-a-half-pound loaf shaped low and wide on a rack rather than pressed into a pan. It goes on naked, the bark sets in the first ninety minutes, and the glaze goes on in two thin coats in the last half hour.
Bare on a rack, shaped by hand, and nothing to hide behind.

What internal temperature is smoked meatloaf done at?
160°F in the center. That is a ground beef number and it is not negotiable the way a steak is. Grinding moves what was the outside of the meat to the inside, so the whole loaf has to reach a safe temperature, not just the surface.
The USDA safe minimum for ground beef is 160°F with no rest requirement. Pull out there, then let it lie on the board fifteen minutes anyway, because the slices hold together better after a rest.
What temperature do you smoke a meatloaf at?
250°F. At 225°F it works and takes closer to four hours, and the extra hour buys nothing but more smoke than ground beef needs. At 275°F the outside sets before the middle catches up.
250°F is the temperature where the bark and the center finally get there together.
Should you smoke meatloaf in a pan or free-form?
Free-form, on a rack. A loaf pan gives you one browned surface out of six — everything else is sitting against hot metal in its own rendered fat, which is braising, not smoking.
Take it out of the pan and let it be looked at.
Lay it out low and wide on a rack and you get five browned surfaces and a bottom that drains. That is five times the bark, and the bark is most of why anyone smokes a meatloaf instead of baking one.
What should go in it?
Two pounds of eighty-twenty ground chuck and a half pound of ground pork. Eighty-twenty is not a suggestion: ninety-ten gives a dry loaf no matter what else you do, because there is nothing in it to render.
The binder is a panade — half a cup of milk poured over three-quarters of a cup of breadcrumbs and left five minutes until it is a paste. Dry crumbs take the juice out of the meat when they ought to be holding it in.
What is the glaze, and when does it go on?
Three parts ketchup, one part brown sugar, one part cider vinegar, whisked cold. That recipe has not been improved on in seventy years, and the vinegar is doing more work than it gets credit for — without acid it is just sweet on sweet.
Two thin coats in the last 30 to 40 minutes, twenty minutes apart. Get to it any earlier and three hours of pit heat turns the sugar bitter.
Why does a smoked meatloaf taste smokier than a smoked roast?
Because grinding multiplies the surface. A whole muscle has one exterior and smoke works inward slowly, which is why a twelve-hour brisket carries a surprisingly thin band of smoke flavor with a lot of beef behind it.
Ground beef is all exterior. Three hours on a meatloaf hits harder than twelve on a packer, so keep a lighter hand on the wood than your instincts beg for.
How thick should you slice it?
An inch. Thinner slices look tidier on a board and fall apart on the way to the plate, because there is no connective tissue holding a loaf together — only the panade and the rendered fat, and both of those are softest while it is hot.
Give it fifteen minutes of rest first. Cold the next morning it lets you slice it thinner, and that is what the sandwich is for.
