What Is Impossible Sausage?
Impossible Sausage is Impossible Foods' plant-based take on breakfast and dinner sausage, sold as fully-cooked patties and links in Savory and Spicy flavors, along with a raw ground "meat from plants" tube version for cooking loose. It's built on the same soy-protein-and-heme platform that made the Impossible Burger famous, reformulated into a sausage casing and seasoning blend meant to compete directly with pork breakfast sausage and Italian-style links, not just other plant-based meat brands. Impossible has been explicit that this product was designed to win over meat eaters at the breakfast table, which is a different bar than most vegan sausage alternatives set for themselves — it's chasing snap, grease, and a familiar spice blend rather than just being "a sausage you can eat if you're vegan."
It's sold in the refrigerated and frozen meat-alternative sections at Kroger, Walmart, and similar grocery chains, generally priced in line with other premium plant-based meat brands like Beyond Meat — expect to pay a noticeable premium over conventional pork sausage per pound, which is standard for this entire product category right now.
Ingredients
The Savory flavor's ingredient list is: water, soy protein concentrate, sunflower oil, coconut oil, then 2% or less of methylcellulose, salt, yeast extract, cultured dextrose, spices, modified food starch, onion powder, dextrose, garlic powder, natural flavors, citric acid, soy leghemoglobin, vitamin E (tocopherols), soy protein isolate, plus added zinc and B vitamins (B3, B6, B2, B12). The Spicy version swaps in dehydrated garlic and onion, crushed red pepper, and cayenne in place of some of the milder seasoning, but runs on the same soy protein and oil base.
The ingredient doing the most interesting work here is soy leghemoglobin — the same heme-carrying protein used in the Impossible Burger, produced through fermentation rather than extracted from meat, responsible for the faint iron-forward "meaty" edge to the flavor and for some of the browning behavior when it cooks. Methylcellulose is what gives the casing its structure and that sausage "snap" when you bite in, standing in for the collagen casing used on traditional links.
How It's Actually Made
The soy leghemoglobin in Impossible Sausage is worth explaining because it's the single most misunderstood ingredient in the entire Impossible product lineup. Leghemoglobin is a heme-carrying protein that naturally occurs in the roots of soy plants, where it helps the plant fix nitrogen. Impossible doesn't harvest it from soybean roots at commercial scale — instead, they insert the gene that codes for soy leghemoglobin into a yeast strain, then ferment that yeast in large tanks the same way you'd brew beer, and purify the resulting protein. It's genetically engineered, but the protein itself is structurally the same molecule found in soy plants, not an animal product, and it contains no meat or animal DNA at any point in the process. That fermentation-based heme is what gives the sausage its faint iron-forward, slightly bloody note when raw and its browning behavior when cooked, mimicking a reaction that in real meat comes from myoglobin.
Beyond that headline ingredient, the rest of the formulation is fairly conventional plant-based sausage engineering: soy protein concentrate and isolate for structure and protein content, a sunflower-and-coconut oil blend for fat and mouthfeel, methylcellulose as a heat-activated binder that firms up when cooked (this is also what creates the casing snap), and a standard spice blend built around sage, garlic, onion, and black pepper for the Savory version, with cayenne and crushed red pepper added for Spicy.
Is Impossible Sausage Vegan?
Yes. Impossible Sausage is fully plant-based — there's no meat, dairy, egg, or other animal-derived ingredient in either the Savory or Spicy formulation. The only allergen flagged on the label is soy, which shows up twice in the ingredient list as both soy protein concentrate and soy protein isolate, so it's a hard no for anyone with a soy allergy regardless of vegan status. Worth noting for context: Impossible has been open that this product line was engineered primarily to appeal to omnivores looking to cut back on meat, not marketed first to the vegan community — but the formulation itself doesn't include anything that would disqualify it from a vegan diet. If you want to double-check any specific SKU or flavor variant before buying, run the label through the spvegan.com ingredient checker.
Nutrition Facts Comparison
Here's how a standard serving of Impossible Sausage compares to Beyond Sausage and a typical Field Roast-style plant sausage, using each brand's published nutrition data.
| Product | Serving | Calories | Protein | Total Fat | Sat. Fat | Fiber | Sodium |
|---|---|---|---|---|---|---|---|
| Impossible Sausage (Savory) | 1 link, 95g | 240 | 14g | 16g | 7g | 5g | 570mg |
| Beyond Sausage (Sweet Italian) | 100g | 250 | 16g | 18g | 8g | 3g | 540mg |
| Quorn Meatless Grounds* | 110g | 100 | 15g | 2g | 1g | 8g | 65mg |
*Quorn's standard grounds are included for reference on fat/sodium contrast only — note that Quorn's non-vegan-labeled grounds contain egg white and aren't a vegan substitute; only Quorn's specifically vegan-labeled SKUs are.
Impossible Sausage and Beyond Sausage land in a similar range on calories, protein, and sodium, with Impossible coming in slightly leaner on fat and a touch higher on fiber per serving. Neither is a "diet" food — both are closer in macros to real pork sausage than to a lean protein source, which is by design, since both are built to replace fatty breakfast and dinner sausage rather than to be a health food.
Taste and Texture
This is where Impossible Sausage tends to win people over even when they walked in skeptical. The casing genuinely snaps when you bite into it, which has been the hardest thing for plant-based sausage to replicate convincingly — most competitors either go casing-less or use a softer wrapper that doesn't deliver the same bite. Cooked on a grill, in a pan, or in the oven, the links hold their shape and brown at the edges the way a pork sausage does, and the seasoning blend reads as genuinely close to a diner-style breakfast link: peppery, a little sage-forward, noticeably salty. The Spicy version brings real heat rather than a token pepper flake garnish. Where it can fall short of the real thing is juiciness — some tasters find it slightly drier in the center than a fatty pork link, and the soy protein base gives a marginally more uniform, less "chunky" bite than ground meat naturally has. It performs well in any application where you'd normally use breakfast sausage or Italian sausage: crumbled into a scramble, sliced into pasta sauce, on a roll with peppers and onions, or split and grilled for a sandwich.
Impossible Sausage vs. Alternatives
| Impossible Sausage | Beyond Sausage | Field Roast-style | |
|---|---|---|---|
| Base protein | Soy protein + soy leghemoglobin | Pea protein | Vital wheat gluten (seitan) |
| Casing snap | Strong, closest to real sausage | Moderate | Minimal; softer, denser bite |
| Allergen concerns | Soy | Pea (less common allergen) | Wheat/gluten |
| Best for | Breakfast links, grilling | Italian-style dishes, grilling | Slicing, pan-searing |
If you have a soy allergy, Beyond Sausage's pea-protein base is the safer pick. If you're gluten-free, both Impossible and Beyond work where Field Roast-style seitan sausages don't. If snap and grill behavior matter most to you, Impossible currently has the edge in most side-by-side taste tests.
Who Should Buy Impossible Sausage
Impossible Sausage makes the most sense for anyone hosting a mixed crowd of vegans and meat-eaters at breakfast or a cookout and wanting one product that satisfies both without a second pan — it's specifically engineered to pass that test. It's also a solid pick if you've tried other plant-based sausages and been let down by a mushy, casing-less texture, since the snap is the category's current differentiator. It's a poor fit if you're avoiding soy, if you're looking for a lower-fat, lower-sodium everyday option (Quorn's vegan grounds or a simple bean-and-grain patty will serve you better there), or if you're chasing a whole-food, minimally processed diet, since this is squarely in the highly-processed meat-analog category regardless of how it compares nutritionally to the pork it's replacing.
Cooking and Storage
The fully-cooked patties and links just need to be reheated — a few minutes in a skillet over medium heat, in the oven, or in an air fryer gets them browned and hot through. The raw ground "meat from plants" tube behaves more like fresh sausage: brown it in a pan the way you would ground pork or Italian sausage out of its casing, and don't be surprised if it releases slightly more moisture than meat does as the methylcellulose sets. All versions are sold frozen or well-refrigerated and should be kept cold until you're ready to cook; like most plant-based meat, texture suffers if you let it sit out and refreeze it.
Common Complaints
The most consistent criticism across reviews isn't about taste, it's about the ingredient list and processing level — this is not a "clean eating" product, and Impossible has never marketed it as one. Some reviewers also note the sausages run saltier than they'd like straight out of the package, and a handful mention the links can dry out slightly if overcooked, since there's less rendered fat to keep them moist than a fatty pork sausage has. None of these are vegan-status issues; they're the same tradeoffs you'd weigh against any processed meat alternative.
Final Verdict
Impossible Sausage delivers on the specific thing it set out to do: a plant-based sausage that snaps, browns, and seasons like the real thing, which is a genuinely hard technical problem that most competitors still haven't solved as convincingly. It's confirmed vegan despite not being marketed primarily to vegans, the ingredient list is honest about what's in it, and it holds its own nutritionally against Beyond Sausage without being dramatically better or worse. The tradeoffs are the ones you'd expect from any processed meat analog — soy allergen risk, a fairly long ingredient list, and a price premium over conventional sausage.
Rating: 8/10 — one of the more convincing plant-based sausages on the market for anyone prioritizing texture and taste over minimal processing, held back half a point by the soy allergen exposure and premium pricing rather than anything about the vegan formulation itself.
