Similarities Between All-Clad NS Pro and HA1

All-Clad’s NS Pro and HA1 collections share several notable similarities. Let’s quickly review.

Hard-Anodized Aluminum: Both collections are made from hard-anodized aluminum. To create this material, aluminum undergoes an electrochemical process that transforms the raw aluminum’s appearance from silvery-white to a dark gray or nearly black finish. This process also enhances the aluminum’s natural rust resistance, making it harder and more corrosion-resistant.

Thickness: NS Pro and HA1 pans are both 4 mm thick, which is thicker than most non-stick cookware. This extra thickness provides increased durability, resistance to warping, and better heat retention than thinner non-stick brands like GreenLife, Gotham Steel, Pioneer Woman, and T-fal.

Weight: The weight of the 12-inch fry pans from both collections is nearly identical. The HA1 pan weighs 3.64 pounds, and the NS Pro pan weighs 3.55 pounds. However, this difference is minimal and barely noticeable during use.

Oven Safety: NS Pro and HA1 pans are oven-safe up to 500°F. However, neither collection is broiler-safe, as the intense direct heat can damage the non-stick surface.

Made In China: All-Clad’s stainless steel collections are made in the USA, but HA1 and NS Pro collections are manufactured in China.

Performance: I’ve cooked a wide variety of meals using both the NS Pro and HA1 collections, including eggs, steak, salmon, vegetables, and more. Both perform incredibly well, with even heat distribution across the cooking surface and the ability to maintain a steady temperature throughout the cooking process.

The triple-layer non-stick coating on both collections is reliable and long-lasting, ensuring that food releases easily and cleanup is a breeze.

Although these pans are heavier and require more time to heat up than thinner non-stick cookware, the even and consistent heat is well worth the extra time and effort.

Difference 1: Handle Design

One of the most significant differences between All-Clad HA1 and NS Pro pans is how their handles are designed.

HA1 handles are shaped like cups, with a round bottom and a deep groove on top. All-Clad made these handles with professional chefs in mind.

The deep groove helps chefs keep a good grip on the handle and stops it from turning in their hands when they pour liquids or put food on a plate. The sharp edges and deep groove keep the chef’s hand in place, even when holding a towel or wearing an oven mitt.

But most home cooks don’t need this kind of handle, and you might find it uncomfortable. The sharp edges from the deep groove can hurt your hand and make the pan feel awkward. If you read reviews of All-Clad HA1 pans, you’ll see many people complain about the uncomfortable handles.

So, when All-Clad made the newer NS Pro pans, they listened to what people said about the HA1 handles. NS Pro handles have a curved shape that fits nicely in your hand. They have a small groove on top that stops your hand from slipping, but it’s not as deep as the HA1 groove, so the edges don’t hurt your hand.

It seems like All-clad is moving more toward this comfort-first style handle. All of its newer collections, including NS Pro, Essentials, and D3 Everyday have it. The older collections, like HA1, D3, D5, and Copper Core all have the cup-shaped handle.

Although I prefer NS Pro handles, there is one advantage of HA1 handles: they’re longer. For example, the 12-inch HA1 fry pan handle is 8.8 inches long, while the NS Pro handle is 7.75 inches long. The extra length keeps your hand further away from the hot pan.

Difference 2: Non-Stick Coating

Another major difference between All-Clad HA1 and NS Pro pans is their non-stick coating. According to All-Clad.com, the NS Pro’s coating is longer-lasting and provides “50% Better Performance than the NS1 collection” (an older version of the NS Pro). However, they don’t mention how it compares to the HA1 collection.

To get a clearer answer, I reached out to All-Clad directly. An All-Clad product expert told me:

“NS Pro features the same PTFE non-stick coating as HA1/Essentials, but the main difference is in the ceramic plasma bonding layer. Ceramic plasma particles are sprayed as a layer between the aluminum and non-stick coating. This strengthens the surface to enable less scratching and longer-lasting non-stick compared to NS1.”

Since the NS Pro is a relatively new collection, only time will tell how well the non-stick coating holds up over extended use. However, I’ve been using HA1 pans for years and haven’t encountered any issues with scratching or degradation of the non-stick surface. Food still glides effortlessly across the pan without sticking.

Given that the ceramic plasma layer in the NS Pro collection is an improvement over HA1’s coating, and considering my positive experience with the HA1 pans, I expect the NS Pro pans to perform just as well, if not better, in the long term.

Difference 3: Shape

All-Clad HA1 and NS Pro pans have different shapes that impact performance. The sidewalls of HA1 pans are steeper and a bit taller, which helps contain food and prevents splattering. It also lets you cook a little more food at once, but not much more.

NS Pro pans’ sides are more sloped and shorter. This shape makes it easier for you to get your spatula under the food, especially when it’s close to the side of the pan.

Another advantage of the NS Pro’s sloped sides is that water evaporates from the pan faster. When searing meat, you want the steam to escape quickly so the pan stays dry. A dry pan helps you get a nice, crispy crust on meats like steak.

Difference 4: Rims

NS Pro pans feature flared rims, while HA1 pans have straight rims. This seemingly small detail can actually make a big difference in your cooking experience.

The flared rims on NS Pro pans make pouring liquids from the pan without making a mess much easier. For example, if you’re cooking bacon and want to save the grease in a jar for later use, the flared rim will help guide the oil into the jar without it running down the side of the pan.

This feature also comes in handy when drizzling a sauce over your food directly from the pan and sliding ingredients out of the pan and onto a plate.

While you can still pour liquids and slide ingredients out of HA1 pans with their straight rims, the liquid is more likely to drip or spill down the outside of the pan.

Difference 5: Lids

NS Pro pans come with stainless steel lids, while HA1 pans come with tempered glass lids.

At first glance, glass lids might seem like the better choice because they allow you to keep an eye on your food without lifting the lid and letting heat and moisture escape. However, in reality, the steam from your cooking often fogs up the glass, defeating the purpose of being able to see through it. You’ll often find yourself lifting the lid anyway to get a clear view of your food.

On the other hand, NS Pro’s stainless steel lids are more durable, won’t break, and are easier to clean. With glass lids, food particles and grease can sometimes get stuck in the space between the glass and the metal rim. You don’t have that issue with stainless steel lids.

Difference 6: Heat Conduction

Heat conduction, or how quickly and evenly a skillet heats up, is key to achieving consistent cooking results. To determine the difference in heat conduction between All-Clad HA1 and NS Pro pans, I performed a simple experiment.

I poured two cups of 55°F water into 12-inch frying pans from both collections and heated them on the highest setting using the same electric burner. As the water heated, the bubbles were uniform across the surface of both pans, indicating even heat distribution. When bubbles concentrate in one area, it’s a sign of hot spots and uneven heating.

In the HA1 pan, the first bubbles appeared after two minutes and 12 seconds, and the water reached a full boil after two minutes and 58 seconds.

The NS Pro skillet showed slightly faster results, with the first bubbles appearing after two minutes and 9 seconds and a full boil achieved after three minutes and 3 seconds.

Although the difference in heat conduction between the two collections was minor, the NS Pro pans did heat up a bit faster. It’s worth noting that as you increase the amount of liquid or plan to boil a large pot of water, the impact of this difference becomes more noticeable.

I conduct this heat conduction test with all the pans I review, and the table below shows how both the HA1 and NS Pro collections compare to the rest of the cookware industry:

Difference 7: Heat Retention

Heat retention is another important factor to consider when choosing cookware. Ideally, you want a pan that can maintain its heat when adding cold ingredients and keep a steady temperature during baking and roasting.

I conducted a simple experiment to compare the heat retention capabilities of All-Clad HA1 and NS Pro pans. After bringing water to a boil in both pans, I removed them from the heat and set them aside to cool. I measured the water temperature in each skillet at 5-minute intervals to see how well they retained heat over time.

After the first 5 minutes, the water temperature in the HA1 pan was 117.9°F, while the water in the NS Pro pan was slightly lower at 116.0°F.

After another 5 minutes (10 minutes total), the water temperature in the HA1 pan dropped to 98.1°F, while the water in the NS Pro pan dropped a bit lower at 97.3°F.

Although the difference in heat retention between the two collections was not substantial, it is still noteworthy. One possible explanation for this difference could be the slight variation in the design of the pans. The HA1 pans have slightly higher and less sloped walls than the NS Pro pans, which may result in less surface area of the water being exposed to the cooler air in the room.

Here’s how both pans’ heat retention stacks up against the broader cookware market:

Pan	Temperature After 5 Minutes	Temperature After 10 Minutes
Xtrema fry pan	142°F	113°F
Made In stainless steel fry pan	121.1°F	106.6°F

Difference 8: Induction Efficiency

To determine which All-Clad collection performs better on an induction cooktop, I conducted a side-by-side comparison using 12-inch skillets from both the HA1 and NS Pro collections. I poured two cups of 55°F water into each skillet and placed them on the same induction burner, setting the temperature to 464°F.

The results showed that the HA1 skillet was slightly faster, with the first bubbles appearing after just 1 minute and 10 seconds and the water reaching a full boil at the 1 minute and 54-second mark.

The NS Pro skillet took 1 minute and 14 seconds for the first bubbles to appear, and the water came to a full boil after 2 minutes and 2 seconds.

While both the All-Clad HA1 and NS Pro collections are induction-compatible thanks to the steel induction plate bonded to the bottom of their aluminum bodies, the HA1 skillet demonstrated a slight edge in terms of heating speed.

Difference 9: Options

The HA1 collection features over 25 products, including essential pieces like fry pans and saucepans and specialty items such as griddle pans, deep chef’s pans, and multi-purpose everyday pans. Some HA1 pieces even have bonus items like wooden trivets and serving spoons.

The NS Pro collection offers a more streamlined selection of around a dozen core products, focusing on essentials like fry pans, saucepans, and sauciers. The NS Pro collection doesn’t include specialty pieces and only offers one cookware set (the HA1 collection provides multiple set options).

Difference 10: Price

All-Clad HA1 pans are generally about 20% cheaper than their NS Pro counterparts, though the exact difference varies by pan and retailer.

The higher price of NS Pro pans is due to additional features like the ceramic plasma layer for enhanced durability, improved handle design, flared rims, and stainless steel lids.

Bottom Line: Should You Buy All-Clad NS Pro or HA1 Pans?

Now that you understand the similarities and differences between All-Clad NS Pro and HA1, it’s time to decide which is right for you.

The three main factors to consider are the handle design, pan shape, and price.

• NS Pro’s ergonomic handles provide superior comfort, while HA1’s grooved handles are secure but can be awkward and uncomfortable.
• NS Pro’s sloped walls and flared rims result in quicker moisture evaporation and cleaner pouring.
• The NS Pro collection is around 20% more expensive than HA1.

For most home cooks, I recommend the NS Pro collection over HA1. While both collections are made of the same high-quality materials and offer excellent performance, NS Pro’s thoughtfully designed handles, pan shape, and rims make it a joy to use in the kitchen. The slightly higher investment in the superior comfort and functionality of NS Pro is well worth it.
