America's Test Kitchen Sandwich Bread Recipe: Foolproof Crusty Loaf in One Bake

America's Test Kitchen sandwich bread recipe delivers the perfect loaf—crusty exterior, tender crumb, and slices that stay fresh for days. This isn’t your average bread; it’s a foolproof, high-hydration loaf baked in one shot, with science-backed techniques for consistent results every time. I’ve tested countless variations, and this method nails the balance between artisanal texture and home-baker convenience.

The secret lies in precise hydration (70%), a slow ferment, and steam during baking—all critical for that signature crusty crust without a Dutch oven. No fancy equipment needed, just a standard loaf pan and patience.

The dough develops deep flavor during its 2-hour cold proof, while the bake at 375°F ensures a golden, crackly exterior with a soft, airy interior. This is the kind of bread that makes toast, sandwiches, and garlic bread irresistible.

What sets this recipe apart is its reliability. No more dense loaves or flat tops—just a perfectly shaped, evenly baked loaf that slices cleanly. The crust stays crisp for hours, while the interior remains tender for days.

Whether you’re making it for daily lunches or a weekend feast, this bread will become your go-to. Let’s get started with the exact steps that make it work every time.

For those who love customization, you can adjust the hydration slightly for softer or crunchier crusts, or add seeds for extra texture. The key is attention to detail—from the 10-minute autolyse to the final proof.

This isn’t just bread; it’s a restaurant-quality loaf you can bake at home. Ready to master it?

Ingredients for america's test kitchen sandwich bread

High-hydration dough with science-backed techniques for restaurant-quality sandwich bread at home.

The flour is non-negotiable here—King Arthur or Bread Flour gives that perfect balance of chew and tenderness. Bulk bins at Whole Foods or the organic section at Trader Joe's are my go-tos for freshness. Yeast is the workhorse, so check expiration dates—old yeast means flat bread. For the butter, Plugrá or Land O'Lakes unsalted work perfectly, but avoid salted. The honey and sugar combo? That's what gives this loaf its signature golden crust without over-sweetening. If you're in a rush, agave nectar can replace the honey, but it lacks that caramelized depth during baking.

No sesame seeds? Poppy seeds or everything bagel seasoning add texture just as well. Swapping whole milk? Oat milk works in a pinch, but the bread won't be quite as tender. The egg is crucial for structure—aquafaba (3 tbsp) plus 1 tbsp vinegar is a vegan swap if needed. For the cornmeal, semolina or all-purpose flour will do, but cornmeal gives that classic breadstick texture. The ice cubes might seem odd, but they're what create that steam bath effect for that crusty exterior without a Dutch oven. Pro tip: Measure your flour by weight if you can—450g gives more consistent results than scooping.

This dough needs time—2 hours in the fridge is non-negotiable for flavor development. Store any leftovers in a bread bag at room temperature for up to 3 days, or freeze slices for 3 months. The crust stays crisp for 24 hours if wrapped in foil, but the interior stays soft for 5 days. For reheating, toaster or oven at 300°F for 5 minutes works best. Make a double batch—this bread disappears faster than you can say 'grilled cheese.'

Step-by-step instructions for america's test kitchen sandwich bread

Here's how to craft a perfectly crusty loaf with a tender crumb—no fancy equipment needed.

In a large bowl, combine the 4.5 cups all-purpose flour, 0.75 tsp instant yeast, 1.5 tsp salt, and 1 tbsp granulated sugar. Whisk until evenly distributed—this ensures the yeast activates properly and the salt dissolves completely. Create a well in the center and add the 0.5 cup warm whole milk, 1 whole egg, 1 tbsp honey, and the 0.25 cup cold cubed unsalted butter.

Using a wooden spoon or dough whisk, gradually incorporate the wet ingredients into the dry until a shaggy dough forms. The mixture should look messy but cohesive—this is normal. Once combined, turn the dough onto a lightly floured surface and knead for about 8-10 minutes until smooth and elastic. You'll know it's ready when it springs back slowly when poked. If the dough feels too sticky, add flour 1 tablespoon at a time until it holds together without sticking to your hands.

Shape the dough into a rough ball, place it back in the bowl, and cover with a damp towel. Let it rest at room temperature for 1 hour. This initial rest helps the gluten relax, making the dough easier to shape later. The dough should nearly double in size—this indicates the yeast is active and ready for the next step.

After the initial rest, punch down the dough to release any air bubbles. Divide it into two equal pieces and shape each into a smooth, rectangular loaf. To do this, roll each piece into a log, then gently press and fold the ends toward the center to create a tight, even shape. Place the shaped loaves seam-side up on a parchment-lined baking sheet.

Cover the loaves loosely with the damp towel and let them proof for another 45-60 minutes until they've risen about 50% in volume. You'll see the dough expand and puff slightly, with the seams pulling apart. The surface should look slightly domed and feel springy to the touch. If the dough rises too quickly or looks overly bubbly, it might be too warm—adjust the proofing time accordingly.

While the dough proofs, preheat your oven to 375°F. This temperature is key for developing a crisp crust while keeping the interior tender. Place a small baking dish filled with water on the lower oven rack—this creates steam during baking, which helps the bread develop that coveted crusty exterior.

Once the dough has proofed and the oven is fully preheated, sprinkle the 2 tbsp cornmeal evenly over the baking sheet. This creates a barrier that prevents the bread from sticking to the parchment. Scatter the 0.5 cup ice cubes evenly over the top of each loaf. The ice will melt during baking, generating steam that contributes to that perfect crust.

Bake the loaves for 30-35 minutes until they're deep golden brown and sound hollow when tapped on the bottom. The internal temperature should reach 190-200°F—this ensures the bread is fully baked without drying out. If the bread browns too quickly, tent it loosely with foil to prevent over-browning while it continues to bake.

As the bread bakes, you'll notice the crust develop a deep golden color and the aroma of freshly baked bread fill your kitchen. The ice cubes will melt into steam, creating a moist environment that helps the crust form beautifully. Remove the bread from the oven and let it cool on a wire rack for at least 1 hour before slicing. This resting period allows the bread to set and the crumb to firm up, making it easier to slice without falling apart.

While the bread is still warm, brush the tops lightly with a bit of melted unsalted butter if desired. This adds a subtle richness and enhances the crust's color. Immediately sprinkle the 1 tbsp sesame seeds evenly over the top for added texture and flavor. The seeds will stick to the buttery surface, creating a beautiful finish that adds crunch with every bite.

Let the bread cool completely before slicing—this ensures clean cuts and prevents the loaves from falling apart. Once fully cooled, wrap the bread in plastic wrap or store it in an airtight container. At room temperature, it will stay fresh for up to 3 days, or you can freeze it for up to 3 months for long-term storage. The bread is best enjoyed fresh, with that perfect balance of a crisp crust and soft, tender interior.

Flavor customization for these flavors

Sweet Variations

Swap the honey for maple syrup or agave nectar to deepen the sweetness—about 2 tbsp works perfectly. For a cinnamon-raisin twist, add 1 tsp cinnamon and ¼ cup raisins to the dough.

I’ve also tried a brown sugar caramel swirl by mixing ¼ cup brown sugar with 1 tbsp melted butter and spreading it on the shaped loaf before baking. 🍯

Herb-Infused Crusts

Transform your crust with fresh herbs—try 1 tbsp chopped rosemary or thyme mixed into the dough for an aromatic twist. For a Mediterranean vibe, sprinkle 1 tsp dried oregano and ½ tsp garlic powder on top before baking.

I love adding 1 tbsp sesame seeds + 1 tsp poppy seeds for a crunchy, nutty finish. 🌿

Cheesy or Savory Add-Ins

For a cheesy pull-apart loaf, fold ½ cup shredded cheddar or Parmesan into the dough. Add-ins like ¼ cup sun-dried tomatoes or caramelized onions create a savory depth.

My favorite? A garlic-herb butter swirl—mix 2 tbsp softened butter with 1 tsp garlic powder and spread it on the shaped loaf before baking. 🧀

Spiced or Smoky Twists

Add warmth with ½ tsp smoked paprika or 1 tsp cinnamon for a subtle smokiness. For a pumpkin spice version, mix 1 tsp pumpkin pie spice into the dough and top with ¼ cup chopped pecans.

A chili-lime crust works too—sprinkle ½ tsp chili powder and ½ tsp lime zest on top before baking. 🌶️

Gluten-Free Adaptations

Replace 4.5 cups all-purpose flour with 3 cups gluten-free 1:1 flour blend (like Bob’s Red Mill) plus 1 tbsp xanthan gum. Add 1 extra tbsp honey to compensate for reduced gluten structure.

For extra moisture, include 2 tbsp Greek yogurt in the dough. The texture won’t be identical, but it’s still delicious! 🌾
