Why I Love Hestan’s ProCore™ Technology: Featuring the Thomas Keller Insignia Collection. A Game-Changer in My Kitchen!

As a passionate home chef, I’ve cooked with all kinds of cookware over the years, but nothing has revolutionized my cooking experience quite like Hestan’s ProCore™ Technology. It’s not just cookware—it’s a tool that elevates every dish I make, and as a Hestan Ambassador, I’m excited to share why this technology has earned a permanent spot in my kitchen.
While ProCore™ Technology is featured in all of Hestan’s cookware collections, today I’m spotlighting the Thomas Keller Insignia Collection. Designed in collaboration with the world-renowned chef, this collection perfectly embodies the power of ProCore™ with chef-inspired details that bring professional-grade performance into the home kitchen.

The Magic Behind ProCore™ Technology
At the heart of Hestan’s ProCore™ Technology is its pure aluminum core, seamlessly integrated into their tri-ply stainless steel cookware. This isn’t your average cookware; the ProCore™ design delivers 35% greater heat conductivity compared to other aluminum-clad cookware. It means faster, more consistent heat, and for someone like me who’s always juggling multiple pots and pans, this makes all the difference.
Why It Matters to Me as a Home Chef
1. Consistent, Even Cooking Every Time
One of my favourite things about ProCore™ is how evenly it distributes heat. Whether I’m simmering a delicate sauce, browning meat for a hearty Spanish-Style Lamb Stew, or searing scallops to perfection, I never have to worry about hot spots ruining my meal.
2. Quick and Responsive Heating
ProCore™ heats up fast, which is a lifesaver when time is tight. Whether sautéing veggies or reducing a sauce, I can trust it to respond instantly to temperature adjustments, giving me complete control over my cooking.
3. Durability That Withstands Daily Use
Hestan’s tri-ply stainless steel with ProCore™ is as durable as it is stunning, engineered to withstand the demands of everyday cooking—even on the grill. In this Piri-Piri Chicken with Spicy Rice video, I put my 6-qt Rondeau to the test directly over high heat, demonstrating its exceptional durability and ability to maintain top-tier performance in any cooking environment.
4. Better Searing, Browning, and Flavour
ProCore™ takes searing and browning to the next level. Proteins caramelize beautifully, locking in flavour and giving my dishes that professional edge. This Salmon with Ponzu Sauce video features succulent King Ora salmon, perfectly seared to crispy-skinned perfection.
5. Thoughtful Design for Real-Life Cooking
The ergonomic handles, drip-free rims, and overall design are proof that Hestan understands what home chefs need. Every detail makes cooking easier and more enjoyable.
My Go-To Thomas Keller Insignia Pieces
2-Quart Saucier
This little powerhouse is a game-changer for sauces, risottos, and reductions. The rounded bottom ensures nothing gets stuck in the corners, making stirring effortless and precise.


Why We Love It
- From the ergonomic handles to the ideal weight and balance, every feature reflects Chef Thomas Keller’s attention to detail. These pieces are as comfortable to use as they are effective.
- The stay-cool heat vent in the handles reduces heat transfer by 20%.
- No more food build-up around the flush rivets—these are designed for easy cleaning and stacking.
- It’s versatile enough for small-batch soups, sauces, or even melting chocolate.
- The ProCore™ aluminum heats evenly, which is crucial for temperature-sensitive recipes
Best Uses:
- Preparing delicate dishes like custards, polenta, or the Dulce de Leche we made for our Mini Egg Millionaire’s Shortbread in this video.
Rondeau (6-Qt & 9-Qt)
These are the ultimate multitaskers. Whether braising short ribs, simmering soups, or even roasting a chicken, the Rondeau is my workhorse. Its wide surface area and straight sides make it ideal for everything from searing to slow cooking.


Why We Love Them:
- The large surface area ensures even cooking.
- Sturdy side handles make stovetop-to-oven transitions easy.
- Incredibly versatile—they’ve replaced several other pots in our kitchen.
Best Uses:
- Baking artisan bread or roasting vegetables.
- Braising meats or making hearty stews, like in this Turkey Au Vin Rosé video.
Universal Lids
I can’t tell you how much I love these lids. They fit multiple pieces of cookware, saving space in my cabinets and always within reach.


Why We Love It:
- The logo steam vent releases steam to aid in controlled cooking, prevent boil overs and eliminates rattling.
- Durable and versatile, transitioning seamlessly from stovetop to oven.
- Helps maintain heat and moisture for perfect braises or reductions.
- Available in 3 sizes: 8.5”, 11” and 12.5”
Best Uses:
- Covering sauté pans or rondeaus for braising.
- Reducing sauces or stocks without splatter.
Why ProCore™ Stands Out
The ProCore™ Technology in the Thomas Keller Insignia collection takes cookware performance to the next level. With these pieces, I feel like I have restaurant-grade tools right in my home kitchen. They not only help me cook better but also make the process more enjoyable and efficient.
Elevate Your Cooking Game

Hestan’s ProCore™ Technology, especially in the Thomas Keller Insignia collection, isn’t just about making good food—it’s about making great food with confidence and ease. If you’re looking to invest in cookware that truly transforms your cooking experience, start here. Trust me, these pieces are worth every penny.
From one home chef to another, this is the cookware I rely on daily—and I promise, once you try it, you’ll feel the same. Your investment is backed by a lifetime warranty, so you can cook with peace of mind.
