What kind of egg ring does McDonald’s use?

McDonald’s is one of the largest fast food chains in the world, known for its burgers, fries, and breakfast menu. Eggs are a staple on their breakfast menu, offered in sandwiches like the Egg McMuffin and platters like the Big Breakfast. But have you ever wondered what kind of egg ring McDonald’s uses to cook their perfectly circular eggs? As an experienced McDonald’s chef, I’m here to provide some insight into the egg rings used at McDonald’s.

Why Do They Use Egg Rings?

McDonald’s uses egg rings to help cook their eggs into a uniform shape and size. Here are some of the main reasons McDonald’s egg rings are useful:

  • Consistency – Using an egg ring ensures every egg is the same size and shape. This is part of McDonald’s focus on consistency across all their restaurants.
  • Speed – The rings help cook the eggs faster by spreading the heat evenly. This allows McDonald’s to serve food quickly during busy breakfast rushes.
  • Convenience – The rings make it easy for cooks to flip and handle the eggs without breaking them.
  • Appearance – The perfect circular shape looks appetizing and appealing when served on breakfast sandwiches.

The consistent sizing and shaping is an important part of the McDonald’s brand. Customers expect the Egg McMuffin they order in New York to look the same as one ordered in Las Vegas. So egg rings help make that possible.

History of McDonald’s Egg Rings

Ray Kroc opened the first McDonald’s in 1955, but it wasn’t until the 1970s that they started serving breakfast. Egg sandwiches were added to the menu, cooked on a grill using round metal rings. According to one account, the first McDonald’s egg rings were actually just circular metal lids from quart-sized paint cans! The lids helped keep the eggs nicely rounded as they cooked.

The paint can lids were soon replaced with proper cooking rings made from metals like aluminum or stainless steel. McDonald’s began sourcing their rings from companies that specialized in making kitchen equipment for restaurants. The switch to professional-grade rings improved consistency even further.

Over the years, the rings have evolved to optimize speed and efficiency in McDonald’s kitchens. But the basic concept remains the same 50 years later.

McDonald’s Current Egg Rings

Today, McDonald’s uses specialized egg rings made just for their restaurants. The rings are manufactured by kitchen equipment companies that supply to large chains and franchises.

Based on employee accounts, McDonald’s currently uses egg rings that are:

  • About 4.5 inches wide
  • 1 inch deep
  • Made from aluminum or stainless steel

The aluminum allows for quick, even heating. Stainless steel provides durability with frequent daily use. The 4.5 inch size makes eggs that fit English muffins perfectly.

Some locations may use silicone or plastic rings instead of metal. But aluminum and stainless steel remain the most common materials.

The rings are designed to lay flat on the grill. McDonald’s pre-cracks and pre-whips their liquid eggs to pour into the rings. The eggs only need to cook for a few minutes before they can be lifted out with a spatula and served.

Egg Ring Features

McDonald’s current egg rings have a few special features that improve cooking:

  • Thin walls – The ring walls are thin so heat passes through quickly, speeding up cook times.
  • Stepped walls – The inner wall is slightly higher than the outer wall. This helps contain the eggs neatly.
  • Vertical handles – Small handles allow cooks to remove the rings safely with spatulas.

These design elements help the cooks efficiently churn out many perfect eggs during the breakfast crunch. The rings are durable enough to be used for years.

Usage and Care

To use the McDonald’s egg rings:

  1. Preheat grill to 350-375°F
  2. Lightly coat the rings with oil or butter
  3. Place rings flat on grill and fill with 2-3 oz of liquid egg mixture
  4. Cook 3-5 minutes until egg is set
  5. Lift ring vertically off the grill with spatula
  6. Assemble sandwich and serve immediately

Proper ring care involves:

  • Cleaning with hot soapy water
  • Sanitizing after each use
  • Polishing with grill brick to remove stuck on residue
  • Storing in a dry location

With regular cleaning and replacement when worn, the rings can be reused thousands of times.

Egg Ring Suppliers

McDonald’s sources their proprietary egg rings from a few major suppliers, including:

  • L&R Manufacturing
  • Lewis Equipment Manufacturing
  • RM Equipment
  • Elite Equipment Solutions

These companies each have decades of experience making quality equipment for fast food franchises. They work closely with McDonald’s to create rings tailored to their specific kitchen needs.

The suppliers provide various styles of rings to suit different menu items. For example, smaller rings for biscuits or thicker rings for sandwiches with sausage and bacon. But the classic 4.5-inch size remains the most widely used.

McDonald’s keeps their official ring specifications confidential. The suppliers follow strict guidelines only available to McDonald’s operations and franchise owners. But the basic aluminum and stainless steel construction remains standard across locations.

Alternatives to McDonald’s Rings

While McDonald’s uses customized commercial-grade rings, there are some alternative consumer products available. For home cooks looking to achieve similar results, these can work in a pinch:

Muffin Rings

Metal muffin rings are a similar shape and size to McDonald’s egg rings. The low walls help eggs keep their round shape during cooking. English muffins can fit perfectly inside.

Crumpet Rings

These circular rings used for baking crumpets are ideal for eggs. The perforated surface allows steam to escape for fluffier eggs too.

Canning Rings

The metal rings from canning jars seal and separate foods. When removed from the jar lid, they can be used on skillets and grills to corral scrambled eggs and cutlets.

Plastic Rings

Food storage lids, jar lids, and plastic rings can also substitute when cooking eggs at home. These are good options for nonstick pans where metal is not advised.

While not exactly the same, these consumer items can mimic the egg rings McDonald’s uses. With some practice at home, you can become your own Egg McMuffin master.

Egg Ring Sizes

McDonald’s famously uses 4.5 inch wide egg rings for most breakfast sandwiches. Here are some other common ring sizes:

Ring Size Description
4 inches Great for biscuits and bagel sandwiches
4.5 inches McDonald’s standard size
5 inches For English muffins and thicker sandwiches
6 inches Oversized option for hearty breakfast platters

The 4.5 inch dimension is perfectly suited for the Egg McMuffin. Home cooks can use these other sizes for different breakfast breads and sandwiches. Metal or silicone rings in these sizes are widely available to purchase online or in kitchen stores.

Egg Ring Materials

McDonald’s uses specialized aluminum and stainless steel rings. Here are some pros and cons of different ring materials:

Material Pros Cons
Stainless Steel Durable, heat conductive, stain resistant More expensive, can react with acidic foods
Aluminum Affordable, heats fast and evenly Prone to warping and pitting over time
Silicone Nonstick, safe for nonstick pans Can melt at high heat, less durability
Plastic Cheap, disposable option Not heat resistant, can leach chemicals

For commercial use, aluminum and stainless steel offer the right balance of durability, performance, and value. Home cooks should choose based on their budget and kitchen needs.

Egg Ring Uses Beyond McDonald’s

While egg rings are a vital tool for McDonald’s breakfasts, they have many other uses:

  • Poaching eggs
  • Shaping pancakes and potato cakes
  • Molding sausage or hamburger patties
  • Rounding fish cakes and crab cakes
  • Shaping homemade biscuits and scones
  • Cutting circular slices of bread for sandwiches

Both commercial and consumer rings have multifunctional potential in home and pro kitchens. Their simple design belies the versatility they offer creative cooks.


McDonald’s iconic egg rings play an integral role in their breakfast success. The consistently round eggs are essential to sandwiches like the Egg McMuffin. Specially designed for efficiency and speed, the rings churn out millions of perfect eggs every year. While the proprietary rings remain a McDonald’s secret, plenty of quality alternatives exist for home use. With the right tools and technique, you can make fast food-style egg sandwiches at home.
