I just finished baking my pastries and was eager to take a photo and showcase my baking skills to my close friends, but I noticed that the crust wasn’t glistening the way I wanted.
The pastries were good but lacked the golden brown appeal. I quickly checked my cookbook and realized I could use egg wash or butter.
Knowing which one to use is quite a dilemma. Luckily, I made a decision, and the results were outstanding. In this post, I will break down the strengths of each method so that you know when, how, and where to use egg wash and butter. Let’s dive in.
Egg Wash Vs Butter
a) Egg Wash?
An egg wash is a mixture of beaten eggs diluted with water, milk, or cream and brushed onto pie crusts or pastries before baking to create a shiny, golden surface. The protein and fat in eggs make it brown through the Maillard reaction.
b) Butter
It adds flavor and shine to baked foods but can make them look speckled. Melted butter can drip into baked goods while in the oven. Using butter if you plan to sprinkle the baked foods with sugar is recommended, as the sugar will hide the speckles.
The differences between Egg wash and butter
1. Ingredients and Preparation
Egg wash consists of beaten whole eggs, egg yolks, or egg whites mixed with milk, water, or cream. The liquid dilutes the egg to create a smooth consistency that’s easy to brush onto dough surfaces to produce the desired effect. E.g., egg yolks mixed with water make a golden color, while egg whites deliver shine without significant color.
Preparing egg wash is quick and requires a fork or whisk to blend ingredients or an immersion blender for an extra-smooth texture.
A butter wash is made from melted butter combined with milk or cream for easier application and a fantastic finish. The melted butter is brushed over baked goods for a golden color and tasty flavor.
Butter wash doesn’t require whipping or emulsifying like egg wash but must be applied warm to prevent solidification. Butter wash preparation is easy but requires reheating if it cools during application.
2. Applications in Baking
Egg wash creates golden finishes on pastries, breads, and cookies. It can also seal edges in hand pies and dumplings to prevent filling leakage. Egg washes enhance the visual appeal of pastries, croissants, and danishes by creating a crispy exterior texture.
Butter is used to enhance flavor and add moisture to baked foods. It is used in recipes that benefit from a soft, golden crust, such as dinner rolls, scones, and biscuits.
Butter washes help infuse the crust with flavors like cinnamon, sugar, or herbs. While not ideal for sealing dough edges, butter’s aromatic quality adds depth to simple baked items.
3. Visual and Textural Effects
The proteins in egg wash react under heat to form a shiny, golden crust to produce a professional finish. Egg washes create a crisp texture that complements laminated doughs and pastries with layers.
It also enhances the adhesion of toppings, such as sesame seeds or sanding sugar, to ensure they stay firmly in place during baking.
Butter creates a softer, rustic crust with a matte golden color. It doesn’t provide the same gloss as an egg wash, but its fat content adds moisture and richness to the crust, which pairs well with softer, tender baked foods. Butter is better suited for recipes with less formal looks, like biscuits or crumbly scones.
4. Flavor
Eggwash adds minimal flavor to baked goods. However, it plays a role in locking in moisture, ensuring the crust doesn’t dry out. This neutrality of egg wash makes it versatile for sweet and savory recipes without altering the overall taste.
Butter is renowned for its rich, creamy flavor, which enhances baked goods. It adds depth and a savory note to bread and pastries, complementing sweet ingredients like sugar and chocolate or savory components like garlic and herbs. The distinctive taste of butter makes it a key ingredient for recipes that rely on flavor.
5. Browning Mechanism (The Maillard Reaction)
Egg washes contribute to browning through the Maillard reaction, where proteins and sugars interact under heat to create a golden-brown crust.
The presence of proteins in egg yolks and whites accelerates this reaction, producing vibrant coloration. This mechanism is why egg-washed pastries have an evenly browned and glossy finish.
Butter provides a layer of fat that interacts with sugars in the dough during baking to facilitate browning. This browning is less intense and doesn’t yield the same glossiness as an egg wash, resulting in a soft, tender crust with a warm golden tone.
6. Cost
Egg wash is economical, requiring only basic kitchen staples like eggs and milk or water. A single egg can yield multiple washes, making it a cost-effective option for large baking batches. However, its use is limited by dietary restrictions, as it is unsuitable for vegans or those with egg allergies.
Although more expensive than eggs, butter is widely available and enriches recipes. However, its practicality may be limited by dietary restrictions, as it’s not suitable for vegans or individuals who are lactose intolerant.
Should I use egg wash or butter on my pie crust?
It is better to use egg wash on your pie crust. While the butter adds more flavor than the egg washes, it is less effective in visual appeal and gives a speckled appearance to pastry.

- Transfer the remaining egg wash to an airtight container.
- Refrigerate immediately and use within 1–2 days.
- Reuse for additional pastry projects or repurpose for scrambled eggs.
What are the main uses of an egg wash in baking and cooking?
Egg wash is versatile and primarily used for the following:
1. Browning and Crisping
The proteins in eggs promote browning and give baked goods a golden crust. This is particularly important for items like pies, bread, and pastries.
2. Adhering Toppings
It is a glue for toppings such as seeds, nuts, sugar, or crumbles, ensuring they stick securely during baking.
3. Sealing Edges
For pastries like empanadas, egg wash helps seal the edges of the dough, preventing them from opening during baking.
4.Coating for Breading
In savory applications, egg wash is essential for breaded items like chicken or fish, as it helps the breading adhere before frying.
Why is butter not an ideal substitute for egg wash?
While butter shares some qualities with eggs, it doesn’t perform the same functions due to these limitations:
1. Melting at High Heat
Butter liquefies when exposed to oven temperatures, causing it to run off pastries or breaded items. This makes it ineffective for sealing edges or adhering toppings.
2. Lack of Protein
Unlike eggs, butter lacks the proteins required for browning through the Maillard reaction. It doesn’t create a uniform golden crust or crispness.
3. Inconsistent Coverage
Butter can lead to a speckled appearance rather than the glossy, even finish achieved with egg wash.
What results can you expect when using butter instead of an egg wash?
Using butter instead of an egg wash changes the outcome of baked goods:
a) Visual
Butter creates a soft, shiny finish but lacks egg wash’s even golden brown hue. The crust may appear patchy or speckled.
b) Texture
Buttered crusts are softer and less crisp.
c) Flavor
Butter enhances the richness and adds a buttery taste, which is desirable in specific recipes, like rustic pastries.
When could butter work as a substitute for egg wash?
Butter can be used in specific circumstances, such as:
1. Flavor-First Recipes
For pastries where a rich, buttery taste is prioritized over crispness or a golden finish.
2. Hiding Imperfections
If paired with sugar sprinkles, butter’s speckled appearance is less noticeable and enhances flavour.
3. Soft Pastries
When a softer texture (rather than crispness) is the goal, such as in certain cookies or shortbreads.
What are some better alternatives to egg wash than butter?
a) Mayonnaise
It mimics egg wash’s effects due to its egg, oil, and vinegar composition. It creates similar glossiness and browning without altering the taste.
b) Yoghurt
Packed with protein and fat, yogurt produces a shiny finish and promotes browning, making it closer to egg wash than butter.
c) Milk or cream
These are commonly used alternatives that provide mild browning and sheen, though not as pronounced as egg wash.
What are the Vegan Substitutes of Egg wash and butter
For vegans, several plant-based alternatives mimic the effects of traditional egg wash or butter in baking:
