Choux pastry, or pâte à choux in French, is one of the most fascinating foundations in the pastry world. Unlike puff pastry, which rises from layers of butter, choux pastry puffs up thanks to steam. That simple difference has given us some of the world’s most beloved desserts: éclairs, profiteroles, cream puffs, churros, and even savory cheese puffs known as gougères.
In this complete guide, we’ll break down exactly what choux pastry is, how it works, the history behind it, and how you can master it at home.

What Is Choux Pastry?
Choux pastry, pronounced “shoo”, is a light dough made from water, butter, flour, and eggs. It’s unique because it is cooked twice: first on the stovetop to form a paste (panade) and then baked or fried.
Instead of yeast or baking powder, choux pastry relies on steam for leavening. When baked at high heat, the moisture inside expands, creating a crisp outer shell and a hollow interior perfect for fillings like cream or custard.
What Is Choux Pastry Made Of?
The magic of choux pastry comes from just four basic ingredients:
- Water or Milk – Water creates a crisper shell; milk adds tenderness and browning.
- Butter – Provides flavor and moisture to generate steam.
- Flour – All-purpose flour works best; it forms the structure when cooked.
- Eggs – The most important element, giving elasticity, richness, and lift.
Optional additions include sugar (for desserts), salt (for flavor), cheese (for gougères), or craquelin (a crunchy cookie topping).
How Is Choux Pastry Made? (Step-by-Step Method)
Making choux pastry might seem intimidating, but once you understand the method, it becomes second nature.
Step 1: Boil
Combine water (or water + milk), butter, salt, and sugar in a saucepan. Bring it to a rolling boil.
Step 2: Add Flour
Dump the flour in all at once and stir vigorously. This forms a thick paste known as a panade. Cook for 1–2 minutes to gelatinize the starch.
Step 3: Cool & Add Eggs
Remove from heat, let cool slightly, then add eggs one at a time. The dough should be smooth, glossy, and pipe-able.
Step 4: Pipe & Bake
Pipe onto trays and bake at a high temperature first (around 220°C / 425°F) to create steam and lift, then lower to 175–180°C (350°F) to dry out the shells.
Step 5: Fill & Finish
Cool completely before filling with pastry cream, whipped cream, or savory mixtures.
What Makes Choux Pastry Rise?
Choux pastry rises thanks to steam. Here’s why:
- The dough has high water content (from both water/milk and eggs).
- In the hot oven, water evaporates into steam, inflating the shell.
- Meanwhile, the cooked flour and coagulated eggs provide structure, holding the shape.
Unlike puff pastry, there are no layers of fat — it’s all about steam power.
The History of Choux Pastry
The roots of pâte à choux stretch back to the 16th century. Early versions, called poupelins, were developed in France and Italy. By the 18th century, chefs like Marie-Antoine Carême refined the technique into the pastry we know today.
The name “choux,” meaning “cabbage” in French, refers to the little round cream puffs that resemble tiny cabbages. Over time, choux pastry became the base for French classics like éclairs, croquembouche, and St. Honoré cake.
What Dishes Use Choux Pastry?
Choux pastry is incredibly versatile. Some of the most popular examples include:
- Éclairs – long pastries filled with cream and topped with chocolate.
- Profiteroles / Cream Puffs – small round choux filled with cream or ice cream.
- Chouquettes – bite-sized choux sprinkled with pearl sugar.
- Croquembouche – a tower of caramel-glued cream puffs, often for weddings.
- Gougères – savory cheese puffs.
- Churros & Beignets – fried versions enjoyed worldwide.
Choux Pastry vs. Other Pastries
- Choux vs Puff Pastry: Puff pastry uses laminated butter layers, while choux relies on steam.
- Choux vs Shortcrust: Shortcrust is dense and crumbly, while choux is airy and hollow.
- Choux vs Filo: Filo is paper-thin and layered, while choux is cooked paste-style.
Variations & Toppings
- Craquelin – a crunchy cookie disc baked on top for extra texture.
- Chocolate Glazes – for éclairs.
- Savory Additions – cheese, herbs, or spices.
- Flavor Variants – matcha, coffee, or fruit purées.
Pro Tips for Perfect Choux Pastry
- Always measure by weight, not cups.
- Cook the flour mixture long enough to dry it out.
- Add eggs gradually until the dough passes the “ribbon test.”
- Never open the oven door early.
- Poke small holes post-bake to release steam and prevent collapse.
Troubleshooting: Why Did My Choux Pastry Fail?
- Didn’t puff? Too dry or too wet dough, wrong oven temp.
- Collapsed? Underbaked or not dried long enough.
- Dense interior? Eggs not incorporated correctly.
- Flat shells? Panade not cooked properly.

FAQs
1. What is choux pastry?
A French pastry dough (pâte à choux) that puffs up with steam to form hollow shells used in éclairs and cream puffs.
2. Is choux pastry the same as puff pastry?
No. Choux is steam-leavened, puff pastry is laminated.
3. Why did my choux not rise?
Too much or too little egg, oven temp issues, or underbaking.
4. Can you freeze choux pastry?
Yes, both unbaked and baked shells freeze well.
