Is Enamel Cookware Safe? What to Know Before You Cook With It

Enameled cookware, from colorful Dutch ovens to classic speckled camp mugs, is a kitchen favorite. It’s easy to clean, doesn’t need seasoning and handles acidic foods like tomato sauce without a metallic taste. But many cooks wonder whether it’s safe, especially once a pot gets older or chipped. Here’s what enamel is, when to be cautious and how to make it last.

What is enamel cookware?

Enamel (also called porcelain enamel or vitreous enamel) is a layer of glass fused onto metal at very high temperature. The result is a hard, glossy coating that bonds to the metal underneath. Common types include:

• Enameled cast iron: heavy Dutch ovens, braisers and skillets. These hold heat well and are popular for stews, braises and bread.
• Enameled steel: lighter stockpots, kettles and camp cookware. These heat faster but don’t hold heat as long.

Because the cooking surface is glass, it doesn’t react with acidic foods and doesn’t need to be seasoned like bare cast iron.

Is enamel cookware safe?

For most cooks, intact enamel cookware from a reputable maker is a safe, inert cooking surface. The questions people usually have come down to three things.

1. Chips and cracks

If the enamel on the cooking surface chips, the metal underneath is exposed. On cast iron that metal can rust, and small loose flakes of enamel aren’t something you want in your food. Many cooks retire a pot once the interior is chipped, or check with the maker, who may advise on warranty or repair. Chips on the outside of a pot are mostly cosmetic, though they can rust if left wet.

2. Older or decorative pieces

Some older or decorative enameled and glazed items were made before current safety standards, and certain glazes have contained lead or cadmium. If a vintage piece or a souvenir item isn’t clearly labeled as food-safe, it’s safest to use it for display rather than cooking.

3. High heat and empty pans

Enamel can crack from sudden temperature changes (thermal shock) or from being heated empty for a long time. Heat it gradually with some oil, liquid or food in the pot.

How to cook with enamel cookware

• Use low to medium heat. Enameled cast iron holds heat so well that medium heat is usually enough, even for searing.
• Add fat or liquid before heating. Avoid preheating an empty pot on high.
• Use wood, silicone or nylon utensils. Metal can scratch or chip the glossy surface. The Nosara teak wood utensil set includes a ladle, slotted spoon and flat spoon that are gentle on enamel.
• Lift, don’t drag. On glass and induction cooktops, sliding heavy pots can scratch both the cooktop and the base.
• Check the oven rating. Enameled cast iron is often oven-safe, but knobs and handles may have lower limits. See our guide to oven-safe cookware.
• Use good mitts. Enameled cast iron handles get very hot. The polka-dot heat-resistant oven mitts are a cheerful option for lifting lids and handles.

Cleaning and care

Let it cool first

Plunging a hot pot into cold water is one of the most common causes of cracked enamel. Let it cool before washing.

Wash gently

Warm, soapy water and a soft sponge are usually enough. Avoid steel wool and harsh scouring powders on the interior. Even if the maker says a piece is dishwasher-safe, hand-washing tends to keep the finish glossy longer.

Lift stuck-on food

Soak the pot in warm water for a while, then use a wooden spoon or a non-scratch pad. For stubborn residue, simmer water with a spoonful of baking soda, let it cool and scrub gently.

Deal with stains

Light-colored interiors stain over time, especially from tomato sauces, curries and coffee. Staining is cosmetic and doesn’t affect safety. A baking-soda paste usually lightens it.

Dry and store well

Dry thoroughly, especially around the rim where enamel may stop and bare metal shows. Store with the lid slightly ajar or a paper towel between lid and pot so moisture doesn’t get trapped.

Enamel vs. bare cast iron

Bare cast iron needs seasoning and doesn’t like long-simmered acidic foods, but it handles high heat and metal utensils well. Enameled cast iron needs no seasoning and is better for tomato sauces and wine braises, but it’s gentler on heat and utensils. Many kitchens have one of each. Our Dutch oven guide explains which type to choose, and our comparison of cast iron, stainless and carbon steel covers the other options.

FAQ

Is it safe to cook in a chipped enamel pot?

If the chip is on the inside cooking surface, it’s safest to stop using it for cooking or check with the maker. Small chips on the outside are mostly cosmetic.

Is enamel cookware non-stick?

Not really. Smooth enamel releases food better than bare metal once it’s well oiled, but it isn’t a non-stick coating.

Can enamel cookware go in the dishwasher?

Some pieces can, according to the maker, but hand-washing helps the finish last longer.

Why is my enamel pot stained?

Foods like tomato sauce and turmeric can stain light enamel. It’s cosmetic; a baking-soda paste usually helps.
