Step 1

Watch the video tutorial and use the step-by-step photos before you begin. Read the recipe instructions and notes before beginning. Make room in the refrigerator for your half baking sheet for steps 6–9.

Step 2

In a large ungreased mixing bowl, whisk the warm milk, yeast, and sugar together in the bowl of your stand mixer fitted with a dough hook attachment. Cover and allow mixture to sit for about 5 minutes or until foamy on top. *If you do not own a mixer, you can do this in a large mixing bowl and in the next step, mix the dough together with a large wooden spoon/rubber spatula. A hand mixer works, but the sticky dough repeatedly gets stuck in the beaters. Mixing by hand with a wooden spoon or rubber spatula is a better choice.*

Step 3

Add the salt, butter, and 2 cups (250g) of flour. Beat on medium speed for 2 minutes, stopping and scraping down the bowl as needed to help the mixture combine. There may still be chunks of butter– that’s ok. Add remaining flour, scrape down the bowl as needed, and beat on low speed until a soft dough forms and pulls away from the sides of the bowl. Dough will be very soft, but not overly sticky. Beat in 2–3 more Tablespoons of flour if dough seems very sticky. Avoid adding more flour than you need.

Step 4

Keep the dough in the mixer and beat on low speed for an additional 3 minutes, or knead by hand on a lightly floured surface for 3 minutes.

Step 5

Lightly grease a large bowl with oil or use nonstick spray. Place the dough in the bowl, turning it to coat all sides of the dough in the oil. Cover the bowl with aluminum foil, plastic wrap, or a clean kitchen towel. Allow the dough to rise in a relatively warm environment for 1.5–2 hours or until nearly double in size. (For a tiny reduction in rise time, see my answer to Where Should Dough Rise? in my Baking with Yeast Guide.)

Step 6

Punch down the dough to release the air. Place dough on a silicone baking mat-lined, parchment paper-lined, or lightly floured baking sheet. (I highly recommend a silicone baking mat because you can roll the dough out in the next steps directly on top and it won’t slide all over the counter.) Gently flatten the dough out into a 10×14-inch (25x35cm) rectangle using lightly floured hands to carefully stretch, but not tear, the dough. Lightly cover and place the entire baking sheet in the refrigerator, and allow the covered dough to rest and chill for 20 minutes. Do not extend this time.

Step 7

Cut the salted butter into 1/4-inch thick slices and, as explained in the recipe note below, make sure the butter is not overly soft. It’s important to note the following 4 tips before you begin laminating in steps 8, 9, & 10: (It’s OK if there are air bubbles in the dough because your rolling pin will pop them. (If the dough tears and butter is exposed, just sprinkle the exposed butter with flour. (If the dough is impossible to roll, try flipping it over. If it’s still impossible to roll, cover and let it rest for 5 minutes before trying again, to let the gluten relax. And (Do not extend the refrigeration times, because the folded dough will begin to over-expand.

Step 8

Remove dough from the refrigerator and set baking sheet aside. I like to keep the dough on the silicone baking mat when I’m rolling it because the mat is nonstick. Working with the longer (14-inch) edge in front of you, line butter down the center of the dough, covering the center third of the dough. Fold one dough edge over on top of butter, and fold other edge on top of that (like folding a business letter). Pinch/seal the two short ends to enclose butter inside. Rotate dough so the long edge is horizontally in front of you. Lightly flour the top of the folded dough and, using a lightly floured rolling pin, roll out to a 9×12-inch (23x30cm) rectangle. Fold dough edges over on top like folding a business letter. Cover dough, place back on baking sheet, and refrigerate 20 minutes. Do not extend this time.

Step 9

Remove dough from the refrigerator and set baking sheet aside. Rotate dough so the long edge is horizontally in front of you. Lightly flour the top of the folded dough and, using a lightly floured rolling pin, roll out to a 9×12-inch rectangle. Fold dough edges over on top like folding a business letter. Rotate dough horizontally and repeat rolling out to 9×12 inches and folding like a business letter. Cover dough, place back on baking sheet, and refrigerate 20 minutes. Do not extend this time.

Step 10

Remove dough from the refrigerator and set baking sheet aside. Rotate dough so the long edge is horizontally in front of you. Lightly flour the top of the folded dough and using a lightly floured rolling pin, roll out to a 9×12-inch rectangle. Fold dough edges over on top like folding a business letter. For the last time, rotate horizontally and roll out to 9×12 inches. Working from a 9-inch side, roll dough up like you would roll up a jelly roll cake or cinnamon rolls. Place 9-inch log on a cutting board and cut into 5 even rolls (just eyeball it, they don’t need to be perfectly even).

Step 11

Grease a 9×5-inch (23x13cm) loaf pan. Place rolls, seam side down, in loaf pan. Cover tightly and allow to rise until slightly puffy, about 45–60 minutes.

Step 12

Preheat the oven to 350°F (177°C).

Step 13

Whisk egg wash ingredients together. Generously brush risen rolls/loaf with egg wash. Bake loaf for 1 hour until golden brown on top, loosely tenting with aluminum foil after 25 minutes to prevent the top from over-browning before the center can cook. For an accurate test of doneness, the bread is done when an instant-read thermometer reads the center of the loaf as 195°F (90°C). (Tip: Keep in mind that the bread will continue to cook for a few minutes as it cools.)

Step 14

Remove from the oven and place loaf pan on a wire rack. Cool for 30 minutes in the loaf pan. Run a knife around the edges of the pan to release the bread, and then remove bread from loaf pan and cool at least 15 more minutes directly on a wire rack before slicing and serving. (Bread tends to fall apart when sliced warm.) Bread may slightly deflate as it cools.

Step 15

Cover and store leftover croissant bread covered at room temperature for up to 3 days or in the refrigerator for up to 1 week. You can also freeze it for up to 3 months and then thaw on the counter or overnight in the refrigerator. Warm up to your liking.
