In a large bowl, whisk together the flour, yeast, and salt.
Gradually add the warm water and mix until a shaggy dough forms.
Turn the dough out onto a lightly floured surface and knead for 8-10 minutes, until smooth and elastic.
Lightly grease a clean bowl with olive oil. Place the dough in the bowl, turning to coat. Cover with plastic wrap or a damp towel and let rise in a warm place for 1-1.5 hours, or until doubled in size.
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Punch down the dough and divide it into 4 equal pieces. Shape each piece into a round ball.
Place the dough balls on the prepared baking sheet, about 4 inches apart.
Bake for 20-25 minutes, or until golden brown and hollow-sounding when tapped.
To serve as bowls, let cool slightly. Cut off the top 1/4 of each bread bowl and scoop out the soft interior, leaving a sturdy shell.
Notes
These bread bowls are best served the same day they are made. Fill them with your favorite hearty soup or chili!
