Is Croissants Ultra Processed?
Not Typically Ultra-Processed
Croissants range from Level 2 (bakery-made with real butter) to Level 3 (commercial/packaged). Traditional croissant-making is mechanically complex — butter is folded into dough in precise layers — but requires no chemical additives. Commercial versions often substitute margarine and add preservatives.
Key Findings
- •Traditional laminated croissant dough creates 27+ layers through mechanical folding — no chemicals needed
- •Commercial croissants frequently substitute margarine for butter, adding trans fats or interesterified oils
- •A bakery croissant with real butter has 6-7 ingredients; a packaged one may have 20+
Why Is Croissants Level 3?
The croissant's flaky layers come from lamination: a block of cold butter is enclosed in dough, then the dough is folded and rolled repeatedly (typically 3 "turns") to create 27+ alternating layers of dough and fat. When baked, water in the butter creates steam that separates the layers. This is purely a mechanical process — traditional croissants need only flour, butter, water, yeast, sugar, salt, and milk. The processing concern arises with commercial croissants that replace butter with margarine (hydrogenated or interesterified vegetable oils) and add dough conditioners (mono/diglycerides, sodium stearoyl lactylate), preservatives (calcium propionate, sorbic acid), and artificial butter flavoring.

How to Read Croissants Labels
- 1
Bakery croissants should list butter, not margarine or vegetable oil blends
- 2
Mono- and diglycerides in packaged croissants are industrial emulsifiers replacing butter's function
- 3
Artificial butter flavor indicates margarine was used instead of real butter
- 4
Frozen "bake at home" croissants often have simpler ingredient lists than shelf-stable packaged ones
Frequently Asked Questions
Are Costco croissants ultra-processed?
Costco bakery croissants use real butter and have a relatively simple ingredient list compared to packaged brands. They are approximately Level 2-3. Check the ingredient list at the bakery counter — it varies by location.
What makes a croissant flaky?
Lamination — repeatedly folding butter into dough to create 27+ alternating layers. When baked, water in the butter turns to steam and separates the layers. This is entirely mechanical. Packaged croissants that skip this process use emulsifiers to simulate flakiness.
Are Pillsbury crescent rolls the same as croissants?
No. Pillsbury crescent rolls are Level 4 — they contain hydrogenated palm oil, artificial flavor, and TBHQ preservative. They lack butter entirely and use chemical additives to create a vaguely similar shape without true lamination.
