The best burger buns! They have a soft and airy crumb, a tender texture and they're made from scratch with just a few staple ingredients. They're one hundred times better than store-bought and well worth the extra effort!
In the bowl of an electric stand mixer whisk together flour, sugar, yeast and salt.
Pour in water, add 1 room temp egg and butter. Roughly stir together with a spatula then using the hook attachment knead mixture on medium-low speed until it's a fairly smooth and elastic dough, about 3 to 5 minutes. If needed add in up to 6 Tbsp additional flour.
Transfer dough to an oiled bowl. Cover (spray wrap with oil, placing oiled side down), and let rest until doubled in volume, about 1 to 1 1/2 hours.
Punch dough down all over to remove large air pockets. Divide dough into 10 equal portions.
Pull and tuck corners and edges under a few times and shape into a ball, over a floured surface.
Transfer 10 dough balls to a parchment paper lined baking sheet, spacing evenly apart. Using your hand slightly flatten to each dough to a 2 2/3-inch circle.
Cover (I just cover with a second baking sheet upside down) and let rest until at least doubled or nearly tripled in volume, about 45 to 60 minutes.
Preheat oven to 375 degrees during last 15 minutes of dough rising. If your oven doesn't brown as well then consider moving oven rack up one level from center.
Very carefully brush buns evenly over the top with the egg wash (the egg that's been whisked with 1 Tbsp water). Be very gentle as to not deflate the buns.
If desired sprinkle tops with sesame seeds.
Bake in preheated oven until buns are golden brown on top and cooked through, about 13 to 16 minutes.
Let cool on a wire rack then slice buns in half when ready to serve.
