Is Italian sausage-and-peppers a summer thing?
I have absolutely no idea.
As a person with, as far as I know, zero Italian heritage, I am not qualified to comment on the appropriate time of year to serve such a dish. What I can tell you is that the first time I encountered a proper plate of Italian sausage and peppers, it was a day much like this one: perfect weather, dinner on a patio, and a platter piled high with sizzling sausages tangled among the sweetest peppers I had ever tasted.
The peppers were soft and silky from cooking, intensely sweet, and somehow managed to steal the spotlight from the sausage itself. I remember going back for seconds. Then thirds. At some point, I stopped pretending I was being polite and simply accepted that I was going to eat an unreasonable quantity of peppers.
I hesitate to say this event was life-changing—I'm not normally given to hyperbole—but nevertheless, here I am talking about a meal I ate twenty years ago.
Call it what you will, those peppers were not your run-of-the-mill bell peppers. They were sweeter, more flavorful, more aromatic, and clearly bred by people who took peppers very seriously.
Over the past twenty years, I've made it something of a personal mission to grow every Italian heirloom pepper I can get my hands on. Along the way, I've come to appreciate that what makes these varieties special is the fact that nearly all of them have been stewarded not by seed companies, but by families and communities. In Chicago, gardeners swear by Melrose. Here in Iowa, Ausilio Thin Skinned Italian developed a devoted following among Italian-American gardeners. For generations, seeds were passed from neighbor to neighbor, with each community preserving the peppers that tasted best in their favorite recipes.
The result is a remarkable collection of heirloom peppers that remain every bit as delicious today as they were decades ago. Here are six of our favorites for frying, roasting, and stuffing.
1. Ausilio Thin Skinned Italian
Let's start close to home—my home, anyway.
If you've spent much time around Des Moines' south side, you've probably heard of the Ausilio pepper. Brought to the United States from Italy by Giovanni "John" Ausilio and Rachel Scarcello in the early 1900s, this thin-skinned frying pepper has been passed down through five generations of the Ausilio family. In 2015, the family donated seeds to the Seed Savers Exchange, which eventually selected the variety for preservation in the Svalbard Global Seed Vault in Norway.
That's an impressive pedigree for any vegetable, but what I find most remarkable is that the pepper survived not because of a university breeding program or a seed company. It survived because a family loved it enough to keep growing it.
And once you taste it, that devotion starts to make sense.
The glossy red peppers typically reach about five inches in length and possess exceptionally thin skins, a trait that makes them ideal for frying. The flavor is mildly sweet with just enough heat to keep things interesting. Traditionally, the family used them for frying, drying, stuffing, canning, and making sardas—savory rolls flavored with dried peppers and sardines.
For me, Ausilio represents everything I love about heirloom vegetables. It's not just a pepper. It's a piece of family history that happened to be delicious enough to survive for more than a century.
2. Melrose
Travel a few hundred miles east and you'll find another pepper with a remarkably similar story.
While the Ausilio family was preserving its beloved frying pepper on Des Moines' south side, Italian immigrants in the Chicago suburb of Melrose Park were doing much the same thing. Beginning in the early 1900s, families brought pepper seeds with them from southern Italy and planted them in backyard gardens and small "pepper patches" throughout the community. Over time, one particular pepper became so closely associated with the neighborhood that it eventually took on the town's name.
That pepper was Melrose.
Rather than coming from a formal breeding program, Melrose developed through decades of careful seed saving by local gardeners. It was shaped by generations of gardeners selecting seeds from the sweetest, most productive plants. By the mid-twentieth century, the pepper had become a fixture of Chicago's Italian-American food culture, appearing in everything from sandwiches and pasta sauces to stuffed peppers and the crispy fried delicacy known as cruschi.
The peppers themselves are typically 4 to 6 inches long with thin skins, thick sweet flesh, and exceptional flavor. They can be harvested green or allowed to ripen to a brilliant red, at which point their sweetness becomes even more pronounced.
Of all the peppers on this list, Melrose may be the one most closely tied to a particular place. More than a century after those first seeds arrived from Italy, gardeners in and around Chicago are still arguing about the best way to cook them—a sure sign that a pepper has done something right.
3. Jimmy Nardello
If Melrose belongs to Chicago and Ausilio belongs to Des Moines, Jimmy Nardello belongs to one family.
The pepper traces its roots to the Basilicata region of southern Italy, where the Nardello family lived before immigrating to the United States in the 1880s. Like so many Italian immigrants of the era, they brought seeds with them from the old country. Those seeds were carefully preserved by the family for generations before eventually finding their way into the hands of seed savers and gardeners across America.
It's difficult to overstate just how beloved this pepper has become.
The plants themselves are relatively compact, rarely exceeding two feet in height, but they produce astonishing numbers of long, slender peppers that often reach 10 to 12 inches in length. As the fruit ripen from green to deep red, they develop an exceptional sweetness that has earned Jimmy Nardello a devoted following among gardeners and chefs alike.
Unlike many sweet peppers, Jimmy Nardello possesses remarkably thin skins. A quick trip through a hot skillet is often all it takes to understand why this pepper has become the gold standard for Italian frying peppers. The flesh softens nicely, the sweetness intensifies, and before long you're wondering why anyone ever thought bell peppers were the default choice for sautéing.
More than a century after the Nardello family carried those seeds across the Atlantic, gardeners are still growing—and arguing over—the pepper. In the heirloom world, that's about as strong an endorsement as a variety can receive.
4. Tolli's Sweet Italian
Not every great heirloom pepper becomes a household name.
Some spend decades quietly earning a reputation among the gardeners who grow them, passed from family to family because they're productive, dependable, and, perhaps most importantly, delicious.
Tolli's Sweet Italian is one of those peppers.
Originally preserved by an Italian-American family in New York, Tolli's produces generous yields of long, tapered peppers with excellent sweetness and a pleasantly mild flavor. While many Italian frying peppers excel in one particular role, Tolli's is remarkably versatile. We've enjoyed it fried, roasted, grilled, stuffed, and sliced fresh into salads, where its sweetness really shines.
What I appreciate most about this variety, however, is its consistency. Every gardener has grown varieties that look fantastic in the seed catalog but somehow fail to live up to expectations in the garden. Tolli's is the opposite. Year after year, it produces attractive peppers, heavy yields, and excellent flavor with very little drama.
Perhaps that's why varieties like this survive.
Not because they're flashy. Not because they become famous. But because generations of gardeners decide they're worth planting again next year.
5. Marconi Red
Every gardener has that one variety.
The one they recommend to friends. The one they grow every year without fail. The one they would keep if they could only grow a single pepper.
For us, that pepper is Marconi Red.
Of all the sweet peppers we sell—Italian or otherwise—Marconi Red is our most popular. And after growing it for years, it's easy to understand why.
The fruit are enormous, often reaching 8 to 12 inches in length and frequently developing the four-lobed shape more commonly associated with bell peppers. Yet despite their size, they retain the sweetness, thin skins, and rich flavor that make Italian peppers so beloved.
In the kitchen, Marconi is remarkably versatile. The peppers are excellent for frying and roasting, and they're sweet enough to enjoy fresh from the garden. But if there's one thing Marconi does better than almost any other Italian pepper, it's stuffing.
Those massive fruit provide an extraordinary amount of room for fillings. Whether you're making traditional stuffed peppers, sausage-stuffed peppers, or something entirely your own, Marconi's sweet flesh and generous size make it a natural choice.
Perhaps that's why it has remained a favorite for generations.
A lot of peppers are sweet. A lot of peppers are productive. Very few combine sweetness, productivity, beauty, and sheer usefulness quite like Marconi Red.
If I were introducing someone to Italian heirloom peppers for the first time, this is probably where I'd start.
6. Golden Treasure
Unlike some of the other peppers we've discussed, Golden Treasure comes with very little historical documentation. Widely accepted to have originated in Italy, some have suggested that it may simply be an orange-fruited selection of Marconi Red. The two do share some similarities, though Golden Treasure tends to produce more 3-lobed fruit with smoother, glossier skins. But whatever its origins, Golden Treasure has earned a permanent place in our garden on flavor alone.
Of all the peppers we grow, this is our favorite for fresh eating.
The fruit are long, glossy, and a beautiful bright orange at maturity. The flesh is exceptionally sweet, crisp, and wrapped in remarkably thin skins. Every year I tell myself that I'll save most of the harvest for cooking. Every year that plan falls apart.
In fact, my son and I spend much of the summer fighting over these peppers. It's a rigged competition—if he eats more veggies, I win. If I get to enjoy them myself, I win.
Of course, Golden Treasure isn't just a snacking pepper.
If you're going to make a truly memorable skillet of sausage and peppers, you're going to want some orange peppers in the mix. The color alone brightens the entire dish, but it's the flavor that really sets Golden Treasure apart. The sweetness complements both the richness of the sausage and the deeper flavors of roasted red peppers, creating a combination that's hard to beat.
The plants themselves are astonishingly productive. Ours produced so heavily that caging became almost mandatory. Without support, I'm not entirely convinced the plants would have remained upright.
When it comes to Golden Treasure, I'm willing to accept a little historical ambiguity in trade for a trove of deliciously sweet, vibrantly colored peppers.
Final Thoughts: Our Favorite Italian Heirloom Peppers
Twenty years after that first plate of sausage and peppers, I'm still chasing the same thing: sweet, thin-skinned peppers that taste like they were bred by people who cared deeply about good food and family traditions.
And, of course, they were.
One of the things I love most about Italian heirloom peppers is that so many of them survived not because of commercial success, but because families and communities refused to let them disappear. They saved seeds from the sweetest peppers, passed them to their children and neighbors, and carried traditions from one generation to the next.
Fortunately for the rest of us, they did.
Whether you choose the history-rich Ausilio, the Chicago favorite Melrose, the legendary Jimmy Nardello, the dependable Tolli's, the giant Marconi Red, or the exceptionally sweet Golden Treasure, you're growing more than just another garden pepper. You're participating in a tradition that values flavor, family, and the simple pleasure of gathering around a good meal.
And that's a tradition worth preserving.
