Haven't you ever wished that your juicy pork chops were perfectly seasoned all the way to the center? Or that your tender pork tenderloin were just a bit juicier and fattier? Or maybe that your flavorful, smoky ribs had a decisive snap to their bite? Sausages are like the Voltron of the grilled pork world, combining the best characteristics of all the other popular cuts of pork into one perfectly juicy, always tender, well-seasoned through-and-through, universe-saving package.*
*Okay, I lied about the universe-saving part.
On top of all that, sausages are inexpensive (they're made with cheap cuts like shoulder and trimmings), come in convenient serving-sized packages, and even at the crummiest of supermarkets, come in at least a half dozen flavors to choose from. They really are one of the ideal foods for the backyard grill.
Ideal, that is, provided two simple things: you start with great sausages, and you don't mess 'em up. That's easier said than done.
With 18 pounds of sausages in hand and a few bags of coal, I fired up the grill last weekend for a marathon of prodding, poking, flipping, burning, slow-cooking, steaming, smoking, and otherwise manhandling the tube steak until I arrived at what I believe is the best method to take them from raw to cooked on the grill. Here's what went down.
The Sausage Torture Chamber
Before we get to the right way to cook sausage, let's talk about some of the wrong ways:
A burnt and busted open casing, sooty flavor, juices lost to the grill gods.
What Happened: This is what happens when you throw a sausage over the highest possible heat. Just like other meats, sausages contract as they cook, and in proportion to how hot they are cooked to. Cook a sausage over high heat, and the casing and the outer layers will quickly get very hot, causing them to contract a great deal. Meanwhile, the raw sausage meat in the center has not contracted at all.
What happens next is sort of like what happens to the Incredible Hulk, but instead of the Hulk growing faster than his clothes, imagine his clothes shrinking in proportion to his body.
The casing and outer layers crack and burst open. Liquefied fat and expelled meat juices from the center pour out onto your fire, causing it to flare up, leaving a sooty deposit all over your sausage. The result is an acrid-tasting sausage with a dry, juiceless center.
An inedible raw center, and a burnt, cracked exterior. Simultaneously overcooked and undercooked. No good.
What happened: Another product of high-heat cooking. This time you wisened up and added the sausages to a moderately hot grill. No good. You still end up with a sausage that cooks too fast, overcooking the exterior before the center has a change to come up to temperature.
The Unloved Grandmother
Okay, so this time you take it to the opposite extreme, cooking the sausage the entire way through on the cooler side of a grill. You get a tiny bit of browning, no bursting at all, and when you pull it off the heat, it looks plump and juicy as can be, but within moments it deflates like a sad balloon, a wrinkled, dry shell of its former self.
What happened: With not enough heat, by the time you get any significant browning on the exterior, the interior layers have already overcooked. Steam and expanded muscle tissue will give the sausage a plump appearance while it's still hot, but as soon as it comes off the grill and cools slightly, it shrivels up again.
The Science of Sausage
Essentially, a well-made sausage is a matrix of interconnected meat proteins. As this web of proteins cooks, it firms up, trapping fat, meat juices, and flavorings in its matrix. Both the fat and the salt give the sausages an advantage over whole cuts of meat when it comes to retaining moisture and flavor during cooking.
Fat plays a vital role, as it's the primary component that gives our mouths the sense of "juiciness." When you bite into a juicy steak? That's mainly the intramuscular fat known as marbling that's making it juicy, not the actual meat juices, which are largely water based. Sausages are a bit like steaks, with the optimal amount of marbling built right into them.
A properly made sausage should have discrete bits of fine fat blended in with the meat in a proportion anywhere from 20% to up to 40% (or even more). Most hover around the 30% mark, making them richer and juicier than almost any steak you'll find outside of Japan.
Salt is also responsible for a sausage's good texture. Aside from seasoning the meat, it also dissolves the protein myosin, one of the major components of muscle fibers. By dissolving it, salt allows meat to retain more moisture as well as shrink less during cooking (the two phenomena are related). This means that given you are cooking your meat to a set temperature, a well-made, properly salted sausage will retain more moisture than a pork chop or steak cooked to the same temperature.
That said, the rules of meat cooking still apply to sausages: you do not want to overcook them. Here's what's going on inside your sausage as it cooks:
- Under 120°F (48.9°C): The meat is still considered raw. Eat your sausage now and it'll taste more wet and mushy than juicy and bouncy. You also might get sick.
- At 120°F: The casing begins to shrink, putting pressure on the meat inside. Simultaneously, the protein myosin begins to coagulate, forcing some liquid out of the muscle cells. In a well-salted sausage, this effect is minimal, as salt has already largely dissolved this protein.
- At 140°F (60°C): The casing and ground muscle and fat inside it are cooked through and opaque. At this stage, some shrinkage will have occurred, but expelled juices are still largely contained by the protein made up from the ground meat. In a well-made sausage, the casing should at this point be adding texture, but is not essential for retaining juices.
- Above 155°F (68.3 °C): Proteins continue to contract, eventually squeezing out so much juice and fat that it can no longer be retained within the protein matrix. Like wringing out a sponge, fat and juice will be squeezed free of the meat and end up collecting under the surface of the skin. Congratulations. What you've got is a lump of dry meat sitting in a grease pool inside a sausage casing. We can do better than this.
The simplest possible solution is to cook the sausage over moderate heat on a grill. I find that by building a two-zone fire with all the coals piled under one side of the cooking grate, I can move my sausages back and forth from cool to hot side, carefully monitoring their internal temperature with a probe thermometer and finagling it so that the internal temperature comes up to 150°F just as the exterior reaches a perfect burnished, crisp, deep brown.
Using this method, you can get an evenly cooked sausage with plenty of smoky grilled flavor.
It works, but it's not easy.
The second solution is much more foolproof, and the one that's recommended by many grilling experts: Poach them first. By covering the sausages in cold water on the stove top and slowly bringing them up to 150°F in their water bath, you can get them cooked perfectly evenly from edge to edge. All that's required is a quick trip to the hot side of the grill, and you're done.
The problem? It's mainly one of flavor, convenience, and opportunity lost. You don't get much smoke flavor because the sausage doesn't spend much time on the actual grill. And if I'm grilling outside, I don't want to futz around indoors with a pan of simmering water. Similarly, if I'm going to take the time to poach a sausage, why wouldn't I use a liquid that will not only add flavor to the sausage, but will benefit from having a sausage simmering in it as well?
What I wanted was a method that offers full smoky flavor of a grilled sausage, the perfectly even, foolproof cooking of the poaching method, and makes full use of the marriage of flavors between a sausage and its accompaniments.
Only one technique I know of offers this solution:
Simmered 'N' Grilled Sausages
By placing the sausages in a disposable aluminum pan (or heavy duty aluminum foil boat) along with a moist, flavorful accopmaniment—say beer, whole grain mustard, sauerkraut, and thyme to go with these bratwurst—you can simmer the sausages directly over the grill, imparting them with flavor from the ingredients in the pan, as well as plenty of smoke from the grill.
I tried this technique with several varying parameters—cooking time, direct vs. indirect heat, sear first and poach after vs. poach first and sear after—and found that the best way to do it is to give the sausages their initial par-cook over indirect heat.
I pile up the coals on one side, place the trays on the hot side until the liquid is just barely simmering, transfer it to the cooler side, cover the grill with the vents open over the sausages (to encourage good convection current) then let them slow cook until they reach close to their desired final temperature of 150°F.
This takes about 20 minutes or so—plenty of time for the smoke, condiment, and sausage flavors to all mingle.
As a technique, it makes sense. After all, it's extremely similar to the slow-start, hot-finish technique I use for Perfect Prime Rib or when I grill a big fat steak. Slower cooking at the start means a more evenly cooked finished product.
Only after it's cooked to I transfer it to the hot side of the grill (which by this point is only moderately hot) to char the sausages and give them some snap and color. You may find that even with the par-poaching technique, a minimal amount of ripping will occur on the skin when you transfer it. That's okay. By this point, the interior of the sausage is already cooked and the protein matrix is doing a fine job of holding the fat and other juices in place (provided you didn't overcook it).
This is a good thing, because you'll have already stuck if a few times with your instant-read thermometer (right?).
There are some more advantages to this method. I've found that once the sausages come to temperature, if you remove the lid of the grill and pile the sausages up as far away from the heat source as possible, they'll stay hot, but won't continue to cook. That means that your sausages are ready when your guests are ready, not the other way around.
All you've got to do is grab a sausage, throw it on the hot side, and in a matter of moments, it's ready to serve along with a few scoops of its condiment. If you look carefully, you can even see the pink smoke ring around the exterior of that sausage, indicating that it's absorbed a good deal of flavor during it's initial cook in the tray.
Just to confirm to my brain what my mouth was already telling it, I cooked up a few more sausages, this time weighing them before and after cooking to see how much fat and moisture was lost during the process.
As you can see, a poorly cooked sausage is dry for a reason: a full 37% of its weight is lost in the form of fat dripping out and water evaporating. Grilling to 150°F using the two-zone-fire shuffle method is much better, producing a sausage that loses only 21% of its weight. Slow-cooking in a pan finished with a hot grill is the best method. Not only does it only incur a 19% weight loss, it also gives the sausage an opportunity to pick up flavor.
The liquids you use to cook your sausage in are only limited by your imagination and availability, but I tend to swing towards the classics.
Bratwurst simmered in sauerkraut and lager is a natural pairing (make sure to save some beer to simmer yourself in while you wait for those sausages). A few thyme sprigs and a scoop of good whole grain mustard didn't RSVP to the party, but they're welcome to crash.

For regular hot dogs (natural casing, please!), I prefer the straight-up clean flavor of plain sauerkraut with a squirt of good spicy brown mustard. If you're from New York, you could also simmer the dogs in a jar of stewed onions. Sabrett makes a good street-cart style jar.

Ok, so this one takes a bit more work, but it's worth the effort! Onions and peppers cooked down in a sweet, vinegary glaze goes perfectly with sweet or hot fennel-scented Italian sausage.
If you want to go 100% grilled, you can always grill the vegetables before adding them to the aluminum tray with the sugar, vinegar, and sausages.

Another slightly-more-work-but-worth-every-extra-minute recipe. Spicy and tart Mexican chorizo (not to be confused with dry-cured raw Spanish chorizo) gets simmered in a tangy tomato sauce punched up with capers, olives, and a handful of cilantro.

Choosing your Sausage
Since I've already spent way too many words on sausages, might as well make this whole guide comprehensive. Starting with a good sausage is as important as how it's cooked. Here's what to look for:
- Choose fresh sausages over pre-cooked. Pre-cooked sausage generally means pre-over-cooked sausage, and there's no way to rescue a sausage that's been overcooked. Look for the words "fresh" on the packaging, and ensure that the sausages inside are still soft and raw looking.
- The exception is emulsified sausages. Emulsified sausages—sausages with a pureed, uniform filling like hot dogs or German-style weisswurst or knockwurst—almost always come pre-cooked, and this is fine. In these cases, look for sausages with natural casings.
- Don't always go for the store-made stuff. Sausage making is not as simple as grinding meat and shoving it in a casing. It requires a bit of technique. I can't count the number of times I've bought "house-made" sausages from reputable butchers only to find them under-seasoned or the fat smeared, resulting in bland, dry results. When in doubt, there's no shame in using a mass-market, widely available brand like Johnsonville or Premio. You can at least be guaranteed that they are properly made.
Can't find good house-made sausages near you and don't want to buy the mass-market stuff? Then consider making your own. Here are a half dozen easy recipes for you:
