Small Sourdough Loaf Recipe: Crusty Mini Boule at Home

Table of Contents

This small sourdough loaf recipe delivers a crackly crust, open crumb, and deep tangy flavor — perfectly sized for everyday baking without the overwhelm.

A small sourdough loaf recipe is exactly what most home bakers actually need: enough bread to enjoy fresh over a couple of days, a manageable dough that fits in a standard Dutch oven, and a process that feels achievable even on a weeknight. Full-size sourdough can feel like a commitment, but scaling things down changes the whole experience. You get all the satisfaction with less waste and a shorter window of timing to manage.

This particular recipe is built around a 300-gram flour base, which yields one compact, beautifully domed loaf — about the size of a large grapefruit. That smaller mass means the dough ferments more predictably, the bake time is slightly shorter, and the crust-to-crumb ratio leans toward that deeply satisfying crackling shell you work so hard for. Whether you are new to sourdough or returning after a long break, this size is forgiving, flexible, and genuinely fun to make.

Small Sourdough Loaf (Mini Boule)

A single rustic mini sourdough boule with a blistered golden-amber crust, wild open crumb, and deeply tangy flavor — all the magic of a full loaf, perfectly scaled down.

Prep

30 mins

Cook

40 mins

Total

14 hrs (including bulk ferment and overnight cold proof)

Serves

1 small loaf (about 6 slices)

Ingredients

50 g active sourdough starter (bubbly and ripe)
200 g bread flour
140 g filtered water (room temperature)
4 g fine sea salt
1 tsp rice flour (for dusting the banneton)

Instructions

1. Mix starter and water together in a medium bowl until the starter is fully dissolved, then add bread flour and salt and mix until a shaggy dough forms; cover and rest 30 minutes.
2. Perform 3 rounds of stretch-and-fold every 30 minutes — grab the dough at one side, stretch it up and fold it over the center; rotate and repeat four times per round.
3. Cover the bowl and allow the dough to bulk ferment at room temperature (75–78°F / 24–26°C) for 4–6 hours until dough is puffed, jiggly, and roughly 50–75% larger.
4. Turn the dough onto a clean unfloured surface, shape it into a tight round boule by tucking the edges underneath and rolling it toward you to build surface tension.
5. Dust a small 6-inch banneton or a bowl lined with a floured linen cloth generously with rice flour, place the shaped boule seam-side up, and cover with plastic wrap.
6. Refrigerate the shaped dough for 8–16 hours (overnight cold proof) — this develops flavor and makes scoring easier.
7. Place a small Dutch oven (3.5 qt) with its lid in the oven and preheat to 500°F (260°C) for at least 45 minutes.
8. Turn the cold dough out onto a small square of parchment paper, dust lightly with flour, and use a sharp lame or razor blade to score a cross or single curved slash across the top.
9. Carefully lower the dough on the parchment into the screaming-hot Dutch oven, place the lid on, and bake covered for 20 minutes.
10. Remove the lid, reduce oven temperature to 450°F (232°C), and bake uncovered for an additional 18–22 minutes until the crust is deep golden-amber and the internal temperature reads 205–210°F (96–99°C).
11. Lift the loaf out onto a wire cooling rack and cool for at least 1 hour before slicing — cutting too early will gum up the crumb.

Tips & Notes

– Your starter must be active and bubbly — feed it 4–8 hours before mixing for best results.
– If your kitchen runs cooler than 72°F, extend the bulk ferment by 1–2 hours and watch the dough, not the clock.
– A small 3.5 qt Dutch oven is ideal; a standard 5 qt will work but the loaf may spread slightly flatter.
– Score straight from the fridge while the dough is cold — it holds its shape and the blade glides cleanly.
– Store the cooled loaf cut-side down on a board at room temperature for up to 2 days, or slice and freeze for up to 1 month.

The logic behind this recipe starts with proportion. When you use 300 grams of bread flour, 215 grams of water, 60 grams of active starter, and 7 grams of fine sea salt, you end up with a dough that is hydrated enough to develop an open crumb but not so slack that shaping becomes a frustrating mess. A 70% hydration range is the sweet spot for beginners and experienced bakers alike — it gives you structure, stretch, and a crust that blisters beautifully in the oven.

The smaller batch also makes autolyse, stretch-and-fold sessions, and shaping much more intuitive. You can feel the dough tightening under your hands in a way that a double or triple batch sometimes obscures. And because you are working with less volume, the loaf fits naturally into a 3.5- to 4-quart Dutch oven, which creates the ideal steam environment for oven spring.

What You Will Need for This Loaf

The ingredient list is short on purpose. You need bread flour for the protein content — it builds the gluten network that holds the loaf’s structure during the long fermentation. All-purpose flour works in a pinch, but bread flour gives you a more resilient crumb and a taller rise. Your starter should be fed and active, meaning it has peaked and still has some dome left when you use it — usually 4 to 6 hours after feeding at room temperature. Water should be lukewarm, around 75 to 80 degrees Fahrenheit. Cold tap water will slow fermentation unpredictably. Fine sea salt brings out the flavor and tightens the gluten, so do not skip it or reduce it. You will also want a medium mixing bowl, a bench scraper, a proofing basket or a bowl lined with a floured kitchen towel, and a Dutch oven with a lid.

How to Make This Small Sourdough Loaf Step by Step

Start by combining your flour and water in a medium bowl. Stir until no dry flour remains, then cover and let it rest for 30 to 45 minutes. This resting period, called autolyse, allows the flour to fully hydrate and begins gluten development without any kneading. After the rest, add your active starter and salt. Use your fingers to work them into the dough, squeezing and folding until everything is fully incorporated. The dough will feel rough at first — that is expected.

Over the next 3 to 4 hours at room temperature (around 74 to 76 degrees Fahrenheit), perform stretch-and-fold sets every 30 to 45 minutes for the first two hours. To do a set, wet your hand, grab one side of the dough, stretch it up as high as it will go without tearing, then fold it over itself. Rotate the bowl a quarter turn and repeat three more times. By the second or third set, you will notice the dough becoming smoother, more elastic, and noticeably more relaxed between folds. After the final fold, let the dough ferment undisturbed until it has grown by roughly 50 to 75 percent and looks domed and slightly jiggly when you move the bowl. Small bubbles on the surface are a good sign.

Turn the dough gently onto an unfloured surface. Shape it by folding the edges toward the center, then flipping it seam-side down. Use your bench scraper to drag the dough toward you a few times, building tension in the surface. This tension is what holds the loaf up in the oven. Transfer the shaped dough seam-side up into a well-floured proofing basket. Cover loosely and refrigerate overnight, or for 8 to 14 hours. The cold retard slows fermentation, deepens flavor, and makes scoring much easier.

When you are ready to bake, place your Dutch oven in the oven and preheat to 500 degrees Fahrenheit for at least 45 minutes. Take the dough straight from the refrigerator, turn it out onto a piece of parchment, and score the top with a sharp blade or a lame at a 30- to 45-degree angle. A single arc cut works well for this size. Lift the parchment and dough into the hot Dutch oven, cover with the lid, and bake at 500 degrees for 20 minutes. Then remove the lid, reduce heat to 450 degrees, and bake for another 18 to 22 minutes until the crust is a deep mahogany brown. The internal temperature should read 205 to 210 degrees Fahrenheit when done. Let the loaf cool on a wire rack for at least one hour before cutting — the crumb continues to set during this time.

Tips for the Best Crust and Crumb

Use a starter that is genuinely active. If it did not double after feeding or smells overly acidic, give it another feed before baking.
Do not rush bulk fermentation. Under-fermented dough produces a dense, gummy crumb. Look for actual volume increase and surface bubbles, not just elapsed time.
Flour your proofing basket generously, especially in the ridges. A mix of white rice flour and bread flour is particularly effective at preventing sticking.
Score confidently. A hesitant, dragging cut tears the dough. One smooth, decisive motion gives you a clean ear.
Resist the urge to slice immediately. Cutting into a warm loaf releases steam and collapses the crumb before it has fully set.
The Dutch oven is not optional. The trapped steam in the first phase of baking is what creates oven spring and that glossy, blistered crust.

Ways to Change This Loaf Up

Once you are comfortable with the base recipe, there are several directions worth exploring depending on what you are in the mood for.

Whole wheat blend: Replace 60 to 75 grams of bread flour with whole wheat flour. The loaf will be slightly denser with a nuttier, earthier flavor and a more rustic crumb.
Seeded crust: Roll the shaped, seam-side-up dough in a mixture of sesame seeds, sunflower seeds, and flaxseed before placing it in the proofing basket. The seeds toast in the oven and add texture to every slice.
Herb-infused crumb: Fold in two teaspoons of dried rosemary or thyme during the second stretch-and-fold set. The herb flavor mellows into the bread as it bakes.
Rye addition: Swap 30 grams of bread flour for dark rye flour. It adds a slightly tangy, mineral note and makes the crust a touch darker.
Jalapeño and cheddar-style: Fold in chopped pickled jalapeños and shredded sharp cheese during the final fold. This variation pairs particularly well with hearty soups and savory dips.
Higher hydration experiment: Once you feel confident with shaping, increase water to 230 grams and see how it affects your crumb openness. The dough will be stickier but the result is often more airy and complex.

How to Store and Reheat Your Small Sourdough Loaf

Sourdough keeps best at room temperature wrapped in a clean kitchen towel or stored cut-side down on a wooden board. A small loaf is meant to be eaten within two to three days. Avoid the refrigerator for whole loaves — cold air stales bread faster than room temperature storage does. If you know you will not finish the loaf in time, slice it and freeze the slices in a zip-top bag. Frozen slices can go directly into a toaster from frozen and come out tasting remarkably fresh.

To refresh a whole leftover loaf, run the cut side briefly under cold running water, then place the whole loaf in a 350-degree oven for 10 to 12 minutes. The crust crisps back up, the crumb softens slightly, and it tastes close to freshly baked.

Frequently Asked Questions

Can you double this recipe? Yes. Simply double all measurements. You will need a larger Dutch oven, around 5 to 6 quarts, and bulk fermentation may take slightly longer since you have more dough mass.
What if my loaf spreads instead of rising? This usually means either the starter was not active enough or bulk fermentation went too long and the dough over-proofed. Try a shorter bulk next time, or feed your starter twice before baking.
Can you bake this without a Dutch oven? You can use a deep oven-safe pot with a tight lid. A cast-iron skillet with a foil tent is a less effective but workable alternative. The crust will not blister as dramatically, but the crumb will still develop well.
How do you know if the dough is properly proofed after the refrigerator? Gently press a floured finger about half an inch into the dough surface. If it springs back slowly and only partially, it is ready. If it springs back immediately, it needs more time. If it does not spring back at all, it may be over-proofed.
