Same-Day Sourdough Bread
Bake sourdough bread in one day with this quick recipe. Using a warm environment and active starter, you can have fresh bread by dinner.
There are days when I wake up craving fresh bread and realize I forgot to mix dough the night before. This recipe was born from that impatience. I experimented with warm spots around my kitchen—the oven with just the light on became my secret weapon—until I could reliably have fresh sourdough by dinner without overnight planning.
The tradeoff is flavor: same-day bread is milder than long-fermented loaves. But when you need bread today, this delivers. The keys are a very active starter and warm fermentation—if either is lacking, this recipe won't work.
Instructions
- 1
Prepare Your Starter (Night Before)
Feed your starter the night before so it's at peak activity in the morning. It should have doubled and still be domed, not fallen. If your starter isn't doubling within 4-6 hours after feeding, this recipe may not work. - 2
Mix Dough (Morning)
Combine starter, warm water, and flour. Mix until no dry flour remains. Cover and rest 30 minutes (autolyse). - 3
Add Salt
Add salt with a splash of water. Mix by squeezing dough through your fingers until incorporated. Cover. - 4
Bulk Fermentation (3-4 Hours)
Keep dough warm (24-27°C/75-80°F). Options: oven with light on, near a warm spot, or proofing box. Perform stretch and folds every 30 minutes for the first 2 hours (4 sets total). - 5
Watch for Signs
Bulk is done when dough has increased 50-75%, is domed and bubbly, and feels airy. In a warm environment, this takes 3-4 hours. - 6
Shape
Turn dough onto lightly floured surface. Pre-shape into a round, rest 15 minutes. Final shape with good surface tension, place seam-up in floured banneton. - 7
Final Proof (1-2 Hours)
Proof at warm room temperature until dough passes the poke test (slow spring back). This takes 1-2 hours in a warm environment. - 8
Preheat
When dough is nearly ready, preheat oven to 250°C (480°F) with Dutch oven inside for 30-45 minutes. - 9
Bake
Turn dough onto parchment, score, and lower into Dutch oven. Bake covered 20 minutes, then remove lid, reduce to 230°C (450°F), and bake 20-25 more minutes until deep golden. - 10
Cool
Cool on wire rack for at least 1 hour before slicing.
Tips & Notes
- Starter must be very active. This recipe depends on a strong, freshly-peaked starter. If in doubt, feed your starter twice before baking day.
- Warmth is essential. Fermentation must be warm (24-27°C) to complete in time. An oven with just the light on often reaches 27°C.
- Don't rush shaping. Even in a same-day bake, proper shaping matters for structure.
- The flavor is milder. Same-day sourdough won't have the deep tang of overnight bread. That's the tradeoff for speed.
- Summer is easier. Warm weather makes same-day baking much more achievable.
Why Same-Day Works
Traditional sourdough takes 24+ hours because wild yeast works slowly at room temperature. By using:
- Very active, just-peaked starter
- Warm water to raise dough temperature
- Warm fermentation environment
...you can compress the timeline dramatically.
Sample Timeline
- 8 AM: Mix dough
- 8:30 AM: Add salt
- 9 AM - 11 AM: Stretch and folds
- 11 AM - 12 PM: Rest and rise
- 12 PM: Shape
- 12:15 PM - 2 PM: Final proof
- 1:30 PM: Preheat oven
- 2 PM: Bake
- 3 PM: Fresh bread!
Creating a Warm Environment
Oven With Light
Many ovens reach 27-30°C with just the light on. Check with a thermometer.
Proofing Box
If you bake regularly, a proofing box is a worthwhile investment for consistent temperature.
DIY Options
- Cooler with jar of hot water
- Microwave with cup of boiled water
- Near a radiator or heating vent
When Same-Day Doesn't Work
This recipe may fail if:
- Your starter isn't active enough (extend timeline or strengthen starter)
- Your kitchen is cold (find a warmer spot)
- You rushed shaping or proofing
If same-day is too rushed for your conditions, try the overnight cold retard method—it's more forgiving.
