Fissler vs. All-Clad vs. Demeyere: Which Cookware Is the Best?

When it comes to high-end stainless steel cookware, All-Clad and Demeyere dominate the conversation.

But there’s a German brand called Fissler that, according to forums and comments on my YouTube videos, might be the best-performing cookware in the world.

To find out for myself, I put the top collections from Fissler, All-Clad, and Demeyere to the test to see how they compare. I tested how fast they heat up, how evenly they distribute heat, how well they retain heat, and how they perform on induction cooktops.

I also cooked dozens of meals in each pan, including burgers, eggs, pancakes, chicken, and much more.

In this comparison of Fissler vs. All-Clad vs. Demeyere, I share the results of those tests. You’ll learn the areas where Fissler is clearly better than All-Clad and Demeyere and other high-end brands—and where it’s not.

I’ll also show you the one category where Fissler outperforms every pan I’ve ever tested.

Contenders

To set the stage, I tested two Fissler collections, Original-Profi and M5-Pro Ply.

The Original-Profi is Fissler’s flagship collection. It features a disc-bottom design. The base, known as the CookStar base, is made from 7 millimeters of aluminum fully encapsulated between two layers of 18/10 stainless steel. All three layers are bonded under over 1,500 tons of pressure into a single, seamless piece.

This process eliminates gaps or weak points, creating a solid disc that delivers excellent heat distribution and long-term durability. The sidewalls are thin (1.3 mm stainless steel), so the pan focuses all its thermal mass at the base, allowing for stable, even heating.

The M5-Pro Ply is fully clad, meaning its five layers extend up the sides. It features a stainless steel exterior, two layers of fast-heating aluminum, and a thin internal layer of stainless steel that acts as a buffer to slow heat transfer so that it spreads evenly across the cooking surface. It’s 3 mm thick overall and offers a more responsive cooking experience than the Original-Profi.

I also tested Demeyere Atlantis Proline, a 7-ply, fully clad pan that’s 5.5 mm thick. It has a tri-layer aluminum core and a unique TriplInduc base made of three magnetic stainless steel layers for better performance on induction cooktops.

All-Clad D3, G5 Graphite Core, and Copper Core, all of which are fully clad and range from 2.6 to 3.1 mm thick, depending on the model:

• D3 has a core of pure aluminum between two stainless steel layers.

• Copper Core features two outer layers of stainless, two layers of aluminum, and a copper core for rapid responsiveness.

• G5 sandwiches a thin graphite disc between layers of aluminum and stainless, offering ultra-fast and even heating with significantly less weight.

Each of these pans uses a different core material—aluminum, copper, graphite—and a different bonding method (disc-bottom vs. fully clad). These differences greatly impact how each pan heats, responds, and performs in real cooking situations, which you’ll see in the upcoming test results.

Heat Conduction

For the first test, I heated each pan on medium using the same burner and measured the center temperature after two minutes. Here are the results:

Pan	Center Temp After 2 Minutes
Fissler Original-Profi (11″)	329°F
Demeyere Atlantis (12″)	350°F
Fissler M5-Pro Ply (10″)	382°F
All-Clad D3 (12″)	451°F
All-Clad Copper Core (12″)	473°F
All-Clad G5 Graphite Core (12.5″)	507°F

These results were clear: speed is not a strength of Fissler. The Original-Profi heated the slowest, followed by Demeyere, then M5. All-Clad’s G5 and Copper Core collections were the fastest, thanks to their highly conductive core materials.

I also performed two heat conduction tests using the Breville Control Freak induction cooktop. First, I set the Control Freak to 400°F and timed how long it took for the center of each pan to reach that temperature. Below are the results:

Pan	Time to Reach 400°F
All-Clad D3	1:00
Demeyere Atlantis	2:03
Fissler Original-Profi	2:16

The second test measured how fast each pan could boil water. With the Control Freak set to 482°F (its highest setting), I recorded how long it took for each pan to bring 32 ounces of water to a full boil (212°F). Below are the results:

Pan	Time to Boil (212°F)
All-Clad D3	4:48
Demeyere Atlantis	4:31
Fissler Original-Profi	5:18

Fissler Original-Profi was the slowest in both induction tests, reaffirming that heat-up speed is not its strength.

Heat Distribution

For the second test, I did the same thing as before—but instead of measuring the center, I measured the edge of the pan. I wanted to see how evenly the heat spread across the surface.

This is where things get interesting.

The Fissler Original-Profi had only a 4-degree difference between the center and the edge. That’s not just better than every pan in this group—it’s the most even heat distribution I’ve ever measured. And I’ve tested over 60 brands. Most have around a 50-degree gap.

Fissler M5 came in second at 29 degrees. The difference in temperature between the center and edge of the All-Clad and Demeyere pans ranged from 45 to 82 degrees. Here are the full results:

Pan	2 Min (center) °F	2 Min (outer edge) °F	Temp diff °F
Fissler Original-Profi 11-inch pan	329°F	333°F	-4°F
Fissler M5-Pro Ply 10-inch pan	382°F	353°F	29°F
All-Clad D3 12-inch	451°F	406°F	45°F
All-Clad G5 Graphite Core 12.5-inch	507°F	447°F	60°F
Demeyere Atlantis 12-inch	350°F	289°F	61°F
All-Clad Copper Core 12-inch	473°F	391°F	82°F

To show how this affects cooking, I placed a hot dog bun across the center and edge of each pan, added weight, and heated them on medium. In the Fissler pan, the bun browned evenly across the full length after 3 minutes.

In the All-Clad pan, the center toasted fast, but the edge stayed pale.

The Demeyere took 3 minutes, but even then, the edge was still under-toasted.

Even heating is critical when you’re searing, browning, or doing any high-heat cooking.

Fissler’s thick base takes longer to heat, but the consistent temperature results in more even cooking without having to rotate the food.

Heat Retention

Heat retention is another key factor to consider when buying high-end cookware. When you add cold ingredients to a pan, you want the pan to stay hot and cook evenly. 

To test heat retention, I heated each pan to 400°F, took it off the burner, and measured the surface temperature after five minutes.

For years, Demeyere Atlantis has been the benchmark for this test. At 159°F, its thick 5.5-millimeter walls consistently held heat better than any stainless steel pan I’ve tested.

However, there is now a new benchmark. After 5 minutes, the Fissler Original-Profi was still at 176°F, 17 degrees hotter than Demeyere.

Fissler M5 performed similarly to All-Clad D3 and Copper Core, which makes sense since their construction and thickness are similar.

Below are the full results:

Pan	Temp After 5 Min
Fissler Original-Profi	176°F
Demeyere Atlantis	159°F
All-Clad D3	132°F
Fissler M5-Pro Ply	131°F
All-Clad Copper Core	128°F
All-Clad G5	115°F

Design

Besides performance, several design elements make Fissler different from All-Clad and Demeyere in both good and bad ways.

Fissler and Demeyere both have welded handles, so the cooking surface is smooth without rivets to trap food or stains.

All-Clad’s handles are riveted, which are stronger but harder to clean.

Years ago, the handle on one of my Demeyere pans snapped off while I was holding it. It’s rare, but with welded handles, this can happen.

The outside of the Fissler Original-Profi handle makes it look like it’s welded in 14 spots, but on the inside, you can only see four subtle marks. So it really only has four welds. I’ve never had an issue with their handles snapping off, but some people have.

In terms of comfort, Original-Profi handles are straight and don’t rotate in your hand, but the sharp corners at the very end can dig into your hand if you grab the pan quickly.

All-Clad’s older collections, like D3 and Copper Core, have handles with a deep groove that prevents rotation but the edges of the groove are uncomfortable. Newer collections like D3 Everyday and G5 have more subtle grooves and are much easier to hold.

Demeyere handles are rounded and smooth—the most comfortable of the three.

Fissler M5 handles feel good too, but they’re so round that they can spin in your hand if it’s greasy or wet.

Another key detail is the rim construction. Fissler M5 and Demeyere pans have sealed rims, so the core layers are not exposed.

All-Clad does not have sealed rims. In fact, they recently updated their care instructions. They stopped calling their cookware dishwasher-safe after settling a lawsuit over exposed, sharp edges that formed after washing them in the dishwasher. Sealed rims avoid that problem completely.

The Fissler Original-Profi collection also features a textured cooking surface called Novogrill; the other pans all have a traditional smooth surface.

Based on my testing, this waffled texture has pros and cons. On the positive side, it keeps oil and fat under the food instead of letting it run to the edges.

Rendered fat stays under the meat and helps it brown more evenly. The texture also creates small pockets of air that help reduce sticking.

On the negative side, you can cook eggs on this surface, but not as easily, and they won’t slide like they do on a smooth surface. You need a spatula to flip them.

Also, cleaning takes more effort because food and oil settle into the tiny ridges. It doesn’t wipe clean like a smooth pan. You have to scrub harder to get into the grooves and remove stuck-on bits.

Bottom Line: Should You Buy Fissler, All-Clad, or Demeyere?

So after all that, is Fissler the best high-end cookware brand? And should you buy it over brands like All-Clad and Demeyere?

It depends on what you value most.

Fissler Original-Profi and Demeyere Atlantis belong in the same category: thick, heavy pans that heat slowly but offer unmatched heat distribution and retention. Between the two, Fissler outperformed in both metrics.

But Demeyere has two advantages: a smoother cooking surface and quieter performance on induction. Fissler’s textured surface can be harder to clean, and like many disc-bottom pans, it buzzes on induction.

I really like them both, but between the two I’m picking Demeyere. The smoother surface and more comfortable handle outweigh Fissler’s advantage in heat properties.

Fissler M5-Pro Ply and All-Clad D3 fall into the second category: thinner, fully clad pans that heat up quickly and respond well to temperature changes. Their performance is nearly identical, but the design differs. Fissler has welded, rivetless handles and a brushed finish. All-Clad has rivets and a polished finish and is significantly less expensive.

So if you want performance and value, go with All-Clad D3 (or the D3 Everyday version). If you want rivetless construction and don’t mind paying more, the Fissler M5-Pro Ply collection is a better option.
