The main differences between the de Buyer Mineral B Pro and the de Buyer Carbone Plus are the pan shape, handle design, steel thickness, and the type of cook each pan is actually built for. Same French brand. Same carbon steel DNA. But these two pans make very different choices — and buying the wrong one is an easy mistake to make.
Quick version: the Mineral B Pro is a classic fry pan with a cool-running stainless handle and a nimble profile built for everyday home cooking. The Carbone Plus is a heavier, thicker, professional-style pan with a distinctive Lyonnaise shape, a helper handle, and serious large-format options. Different tools. Different kitchens.
The de Buyer Mineral B Pro: What It Is and Who It’s For
The Mineral B Pro is de Buyer’s answer to one of carbon steel’s most common complaints: the handle burns you. That’s it. That’s why this pan exists.
The cooking body — the actual carbon steel pan — is essentially the same as the standard Mineral B. What’s different is the cast stainless steel “French curve” handle with built-in heat stop technology. It stays noticeably cooler during stovetop cooking. Not cold. But you can grab it mid-cook without instinctively pulling your hand back.
Full Description
Carbon steel body with beeswax factory coating (wash it off before the first cook)
Three sizes: 8″ at 2.62 lbs, 9.5″ at ~3.17 lbs, 11″ at 3.4 lbs
Classic Western fry pan profile — sloped sides, designed for tossing and sautéing
Single long handle — no helper handle
9.5″ model has a 6.9″ usable cooking surface
Made in France. Obviously.
The Handle — The Whole Point of This Pan
Here’s the thing about carbon steel handles: they conduct heat. All of it. Fast. The standard Mineral B has a riveted carbon/stainless handle that becomes untouchable within a few minutes of cooking.
The Pro’s cast stainless handle with heat stop technology changes this in a real, practical way. You can reposition the pan. Tilt it. Check the bottom of your protein — all without reaching for a towel first. Customers call it out constantly in reviews, and it’s genuinely the most meaningful upgrade in the entire Mineral B lineup.
According to the American Burn Association, contact burns from cooking surfaces and cookware handles are among the most common household burn injuries — so a handle that runs cooler isn’t just a comfort upgrade, it’s a legitimate safety improvement.

Classic fry pan profile is versatile: eggs, proteins, vegetables, sautés
Lightweight compared to cast iron; easier to maneuver
Naturally non-stick after a few rounds of seasoning
Works on every heat source
What doesn’t:
Only three sizes — no large-format options
Oven use is limited to 10 minutes at 400°F
Metal utensils can scratch the seasoning
Some users find the 11″ heavy (it’s 3.4 lbs — make your own call)
No helper handle on any size
Who Should Buy the Mineral B Pro?
Daily home cooks. People who want carbon steel performance without the handle headache. If you cook in the 8–11″ range and move pans around frequently, this is a strong pick. Also great if you’re coming from nonstick and want a more natural, coating-free pan without a brutal learning curve.
Not for you if you need anything bigger than 11″. Simple as that.
The de Buyer Carbone Plus: A Different Animal Entirely
The Carbone Plus isn’t just a bigger, heavier version of the Mineral B Pro. It’s a fundamentally different pan — different shape, different weight philosophy, different intended use.
It has a Lyonnaise profile. That’s a French fry pan design with high, curved, flared sides and no sharp interior angles. Food slides out of it. Literally — the geometry guides food from pan to plate naturally. It’s the kind of pan that’s been a fixture in French professional kitchens for generations, and it shows.
Full Description
Heavy-quality carbon steel, 3mm thick construction — this is serious
Lyonnaise profile: high flared sides, 5.1cm tall, curved skirt with no sharp angles
Two handles: primary strip steel handle + riveted helper handle
No factory coating — arrives raw, season immediately
36cm version holds ~4 quarts (3.8 liters)
Made in France
That size range. 50cm. That’s nearly 20 inches. This pan goes places the Mineral B Pro can’t follow.
The Lyonnaise Shape — This Matters More Than You Think
Standard fry pan: sloped sides, good for tossing, general purpose.
Lyonnaise: high, curved, generous sides with no sharp corners. The curved interior isn’t just aesthetic — it means food moves differently. You tip the pan and things slide out cleanly. No scraping, no awkward flip over the edge. For plating, for sauces, for anything where you want the food to move with the pan rather than against it — this shape wins.
But. It’s not as nimble for small quantities. Cooking two eggs in a 36cm Lyonnaise pan is a bit ridiculous. Tossing vegetables takes more effort because the higher sides create more resistance. It’s a trade-off, and it’s worth thinking about before you buy.
A 2019 study in the journal Food Research International found that pan geometry significantly affects heat distribution patterns and browning consistency — which is part of why the Lyonnaise shape has remained a professional kitchen staple for so long despite having a more specialized profile.
Handle Design
Two handles. Both get hot. No heat stop technology here.
The primary strip steel handle is riveted firmly and does its job — but it conducts heat. You’ll want an oven mitt or kitchen towel. The helper handle on the opposite side is less about cooking style and more about necessity: at 30cm and above, this pan gets heavy. The 36cm hits nearly 7.72 lbs before you’ve put any food in it. You need that second handle.
Features at a Glance
Steel thickness: 3mm — holds heat longer, slower to heat up than the Mineral B Pro
No factory coating: skip the beeswax removal step; season right away
Cooking surface: natural non-stick develops with seasoning and use
Heat retention: excellent — the thick gauge keeps temperature stable under load
Induction: listed as compatible (confirm by size before purchasing)
Care: hand wash only, dry immediately, oil after each wash
Carbone Plus Pricing
Pricing here is… interesting. It doesn’t scale the way you’d expect.
Yeah, the 40cm is cheaper than the 36cm. And the 50cm is cheaper than the 30cm. Import pricing, batch production, available stock — who knows. But it means the large-format sizes are more accessible than you might expect.
Pros and Cons
What works:
Six size options, including massive large-format pans up to 50cm
Lyonnaise profile makes plating and sauce work genuinely easier
Helper handle is practical and thoughtful on larger sizes
4.6 stars across 1,739 reviews — the strongest rating in this comparison
What doesn’t:
Both handles get hot. Towel required, always
Heavy. The 30cm at 5.29 lbs is manageable; the 36cm at 7.72 lbs is a workout
Not nimble for small quantities or delicate foods
Lyonnaise shape isn’t ideal for tossing the way a standard fry pan is
Induction compatibility varies — double-check before buying
Who Should Buy the Carbone Plus?
Serious home cooks and professionals who cook at volume. Anyone who needs a large pan — and I mean really needs it, not just “it’d be nice.” If you’re cooking for a crowd regularly, running a restaurant, or just want the most durable, heat-retentive carbon steel pan de Buyer makes in the consumer space, this is it.
Also a great fit if the Lyonnaise shape appeals to you specifically — for plating, for sauces, for that distinctly French way of working with a pan.
Not for you if you want a nimble, everyday pan for eggs and weeknight cooking.
Mineral B Pro vs Carbone Plus: The Real Head-to-Head
Handle Comfort: Not Even Close
The Mineral B Pro wins. Full stop.
Cast stainless with heat stop vs. strip steel with no heat management whatsoever. If you’ve ever grabbed a carbon steel handle after 5 minutes on a gas burner, you know exactly what the Carbone Plus experience is like. It’s manageable — chefs do it every day — but it requires habits (towel always nearby, always) that the Mineral B Pro doesn’t demand.

Serious Eats’ cookware testing consistently finds that carbon steel outperforms both cast iron and stainless for heat-up speed and maneuverability — an advantage the Mineral B Pro maximizes, while the Carbone Plus trades some of that speed for sustained heat retention via its thicker gauge.
Heat Behavior: Fast vs. Steady
This is the steel thickness difference playing out in real life.
The Mineral B Pro heats up quickly and responds fast when you adjust the heat. Turn the flame down — the pan follows. That’s great for precise cooking: fish, eggs, vegetables that go from raw to overdone in 30 seconds.
The Carbone Plus takes longer to come up to temperature because of that 3mm steel. But once it’s hot, it stays hot. Load it with cold proteins straight from the fridge — the temperature barely drops. That’s what you want for searing large quantities or cooking thick cuts where you need sustained, even heat.
Neither approach is wrong. They’re just different tools.
Size: Carbone Plus by a Mile
The Mineral B Pro tops out at 11″. The Carbone Plus goes to 50cm. If you need anything over 11″, you’re buying a Carbone Plus. That’s the decision made for you.
Price: It Depends on the Size
At the smaller end (8″–9″), the Carbone Plus is actually cheaper. Mid-range (around 11″–12″), prices cross over and the Mineral B Pro becomes the better value. At large formats, you’re only looking at the Carbone Plus — no competition.
Seasoning: One Less Step with the Carbone Plus
The Mineral B Pro ships with a beeswax coating that prevents factory rust — practical, but it means you need to wash it off before your first use. The Carbone Plus arrives raw. No coating to remove. Rinse it, dry it, and start seasoning immediately.
Minor difference. But if you’re impatient to cook — and who isn’t — the Carbone Plus gets you there faster.
How to Season Both Pans (It’s Mostly the Same)
Mineral B Pro: First Use
Hand wash with warm water and a small amount of dish soap — just this once, to remove the beeswax
Dry completely on the stovetop over low heat for 2–3 minutes
Increase to medium-high gradually
Apply a very thin layer of neutral oil — grapeseed, flaxseed, vegetable — using a paper towel (then wipe most of it back off; less is genuinely more here)
Heat until the oil begins to smoke — about 10 minutes
Remove from heat, cool for 10 minutes
Wipe dry, then reheat to medium-high for 2 more minutes
Let cool completely before storing
Carbone Plus: First Use
Skip step one. No beeswax to remove — just rinse with warm water, dry thoroughly, and go straight to the oil and heat process above.
The thicker steel takes slightly longer to come up to temperature, so be patient. Don’t crank the heat trying to speed it up. You’ll warp it. Or at least create uneven seasoning.
Maintaining Either Pan
No dishwasher. Ever.
No harsh soaps after the first wash
Dry immediately — carbon steel rusts faster than you’d think
A light oil wipe after drying extends the seasoning significantly
Cook fatty things first: bacon, duck fat, anything with natural oils — it builds seasoning faster than vegetables ever will
Data from Cook’s Illustrated’s long-term carbon steel testing shows that pans seasoned with multiple thin layers of oil — rather than one thick application — develop a more durable, even non-stick surface over time. Patience pays off.
Handle comfort dominates the positive feedback. Customers consistently mention grabbing the pan mid-cook without issue — and that’s the upgrade they paid for. Non-stick performance after proper seasoning gets strong marks. Heat response described as fast and controllable.
On the negative side: scratching complaints from metal utensil users (use wood or silicone, honestly), and a few customers describing the 11″ as heavier than expected at 3.4 lbs.
Carbone Plus (4.6★ — 1,739 reviews)
Higher rating, bigger sample size. Customers praise even heat distribution and the non-stick surface that develops after seasoning. One reviewer specifically called it out for blackening fish — the heat retention of the 3mm steel makes that kind of high-heat cooking genuinely effective.
Durability gets mentioned a lot — “will last a lifetime” appears in multiple reviews. The usual caveats apply: rust shows up if you store it wet, and the larger sizes are genuinely heavy.
A Statista consumer cookware survey found that durability and long-term value rank as the top purchasing factors for premium cookware buyers — which explains why the Carbone Plus’s “lifetime pan” reputation drives such strong satisfaction scores despite its weight and hot handles.
Where These Pans Fit in the de Buyer Lineup
De Buyer makes a lot of carbon steel. Here’s how these two fit:
Mineral B: Standard consumer pan, carbon steel handle, beeswax coating, six sizes — the entry point
Mineral B Pro: Same pan, better handle, three sizes — the daily driver upgrade
Carbone Plus: Thicker, professional Lyonnaise profile, helper handle, six sizes — the workhorse
Prima Matera: Copper-lined carbon steel — the top of the line, and a different conversation entirely
The Mineral B Pro and Carbone Plus aren’t really competing for the same buyer. The Pro is for the home cook who wants handle comfort and a versatile everyday pan. The Carbone Plus is for the cook who needs volume, heat retention, and large-format options. Most people who compare these two end up realizing — pretty quickly — that one of them clearly fits their kitchen and the other doesn’t.
