America's Test Kitchen Sandwich Bread Recipe: Foil-Sealed Crust and Pillowy Softness

This America's Test Kitchen sandwich bread recipe delivers the perfect balance of foil-sealed crust and pillowy softness—the kind that transforms any sandwich into a gourmet experience. After years of testing, we've perfected the hydration ratio and kneading technique to ensure consistent results every time.

The secret lies in precise dough development and controlled baking temperatures that create that signature crisp crust while keeping the interior tender.

The dough begins with a straightforward mix of flour, water, yeast, and salt, but the magic happens during the 30-minute kneading and 2-hour proofing—critical steps that build gluten structure for that ideal texture.

We use a foil-sealing method during baking to trap steam, creating that signature crisp crust without drying out the interior. This method ensures your bread stays fresh for days, making it perfect for toast, PB&J sandwiches, or charcuterie boards.

What sets this recipe apart is its reliability—no more burning the crust or ending up with dense, tough bread. The 350°F oven temperature and 20-minute baking time (with foil) create that perfect contrast between exterior and interior.

Once you try this method, you'll never go back to store-bought loaves again. The crust is just crisp enough to hold up to butter, while the crumb remains soft and airy.

This recipe works equally well for classic white, whole wheat, or even sourdough variations—just adjust the hydration slightly based on your flour type. Whether you're a beginner or an experienced baker, the clear instructions and foolproof technique guarantee success. Let's get started on your perfect loaf!

Ingredients for america's test kitchen sandwich bread

The perfect blend of flour, yeast, and butter creates America's Test Kitchen's legendary sandwich bread.

The flour is non-negotiable here—King Arthur or Gold Medal gives that signature soft crumb. I always grab a 5-pound bag from King Arthur's website for consistent results, but any high-protein all-purpose works. The yeast? Fleischmann's instant yeast dissolves faster in the dough, saving you a proofing step. Warm water is key—110°F activates the yeast perfectly without killing it. Too hot? Wait 5 minutes. Too cold? Microwave for 10 seconds. The butter should be cold and cubed—this prevents overdevelopment during kneading, which keeps the crumb tender.

No instant yeast? Active dry yeast needs 5 minutes in warm water first. Short on butter? Olive oil at half the amount works, but the crust won't be as crisp. The sugar? Raw cane or white granulated both work—just don't skip it entirely. The salt is where precision matters: Diamond Crystal kosher salt measures differently than table salt. Use a kitchen scale if you're unsure. For the eggs, room temperature is ideal, but if you're in a hurry, whisk them vigorously for 30 seconds to mimic the effect. The foil? Heavy-duty aluminum holds steam best—don't use Reynolds Wrap.

Store the dough in an airtight container for up to 12 hours in the fridge if you need to proof overnight. Once baked, this bread stays fresh for 4-5 days at room temperature, wrapped in a clean kitchen towel. For longer storage, freeze the loaf unwrapped for 1 hour first, then wrap in foil. To revive, warm at 350°F for 5-10 minutes. The foil-sealed crust trick? It's worth the extra minute—your sandwiches will thank you. I make two loaves every Sunday and freeze one for the week.

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

Here's how to bake bread with a foolproof foil-sealed crust and cloud-soft interior every time.

In a stand mixer fitted with the dough hook attachment, combine the 4 cups all-purpose flour, 0.03 oz instant yeast, 0.03 oz granulated sugar, and 1.5 tsp salt. Mix on low speed for 30 seconds to blend the dry ingredients thoroughly. This ensures even distribution of yeast and salt throughout the dough.

Next, add the 1 whole large egg and 0.25 cup cold cubed unsalted butter to the bowl. Increase the mixer speed to medium and let it run for 1 minute until the butter begins to soften and incorporate into the flour mixture. This step is crucial—cold butter creates pockets of fat that yield tender, soft bread.

With the mixer still running, gradually pour in the 1.25 cups warm water (about 110°F) through the feed tube. Mix on medium speed for 3-5 minutes until the dough comes together and begins to pull away from the sides of the bowl. You'll know it's ready when it forms a shaggy mass that clings to the dough hook. If the dough feels too sticky, add 1 tablespoon flour at a time until it reaches a smooth, elastic consistency.

Continue kneading the dough on medium speed for 5-7 minutes until it becomes smooth, elastic, and slightly tacky to the touch. The dough should pass the "windowpane test"—stretch a small piece between your fingers until it's translucent and thin enough to see light through it without tearing. This indicates proper gluten development, which gives the bread its structure and chewiness.

If the dough feels too soft or sticky after kneading, add 1 tablespoon flour at a time until it reaches the right consistency. Conversely, if it feels too dry, add 1 teaspoon warm water to help it come together. The ideal dough should be smooth, slightly tacky, and spring back slowly when poked with a finger.

Once the dough is properly kneaded, remove it from the mixer and transfer it to a lightly greased bowl. Cover the bowl with a damp kitchen towel or plastic wrap and let it rise in a warm place for 1-2 hours, or until it has doubled in size. The dough should feel light and airy, with a slightly puffy appearance. This first rise is where the yeast does its magic, creating air pockets for that signature pillowy texture.

Turn the risen dough onto a lightly floured surface and gently punch it down to release the air. Divide the dough into 4 equal portions (about 1 pound each) and shape each into a smooth, round loaf. To do this, cup your hands around the dough and gently roll it back and forth on the surface while applying even pressure. This creates surface tension, which helps the bread hold its shape during baking.

Place each shaped loaf onto a 12x17-inch sheet of parchment paper, leaving 2 inches of space between them. Cover the loaves loosely with a damp towel and let them rise again for 30-45 minutes, or until they've puffed up slightly and feel light to the touch. The second rise is shorter but essential—it ensures the bread maintains its structure while baking.

While the loaves are rising, preheat your oven to 375°F. Once the oven is fully heated, carefully transfer the parchment paper with the loaves onto a baking sheet. This makes it easy to slide the bread into the oven without tearing the dough.

Here's the secret to that perfect crust: tightly wrap each loaf in 1 sheet of heavy-duty aluminum foil, sealing the edges completely to create an airtight seal. This traps steam inside the loaf, which steams the bread as it bakes, resulting in a soft, pillowy interior. Without the foil, the crust would dry out before the center cooked through.

Bake the foil-sealed loaves for 25-30 minutes, until the bread feels firm to the touch and the internal temperature reaches 190°F when measured with an instant-read thermometer. The bread should sound hollow when tapped on the bottom—this is your cue that it's fully baked.

Remove the loaves from the oven and carefully unwrap the foil. Immediately transfer the bread to a wire rack to cool completely. This step is critical—cooling on a rack prevents sogginess and allows the bread to set properly. Once cooled, slice the bread with a serrated knife for clean, even cuts. The result? A crust that's crisp yet tender, with a soft, airy crumb that's perfect for sandwiches.

Health benefits of this america's test kitchen sandwich bread

Whole Grain Boost

This bread recipe is easily adaptable to include whole wheat flour for added fiber and nutrients. Replace 2 cups of all-purpose flour with 2 cups whole wheat flour—just be prepared for a slightly denser crumb.

The extra fiber content helps keep you full longer and supports digestive health. I’ve found that adding 1 tablespoon vital wheat gluten to whole wheat dough helps mimic the light texture of all-purpose flour. 🌱

Low-Calorie Option

For a lighter version, reduce the butter to 0.125 cup (half the original amount) and replace the remaining fat with 1 tablespoon olive oil. This cuts about 100 calories per loaf while still delivering that signature softness.

The olive oil adds subtle fruity notes that complement the bread beautifully. Pair it with hummus or avocado for a satisfying, lower-calorie sandwich.

Gluten-Free Adaptation

Gluten-free bakers can use a 1:1 gluten-free flour blend (like King Arthur’s) and add 1 teaspoon xanthan gum to mimic gluten’s structure. Expect a slightly denser texture, but the foil-sealing method still creates a tender interior.

I recommend increasing the water by 2 tablespoons to compensate for the blend’s dryness. Always check your blend’s hydration requirements first—some need more liquid than others. 💪

Protein-Packed Upgrade

Boost protein by adding 2 tablespoons vital wheat gluten or ¼ cup ground flaxseed to the dough. The gluten adds elasticity, while flaxseed contributes 3 grams of fiber and omega-3s per tablespoon.

For extra richness, fold in 2 tablespoons Greek yogurt when mixing—it replaces butter without sacrificing moisture. This version is perfect for post-workout meals or high-protein diets.

Blood Sugar Balance

To slow carbohydrate absorption, replace ½ cup all-purpose flour with ½ cup almond flour (though this will alter texture). The almond flour adds healthy fats and 4 grams of protein per ¼ cup, helping stabilize blood sugar.

For a sweeter touch, reduce the granulated sugar to 0.015 oz and add 1 teaspoon cinnamon—it enhances flavor while supporting metabolic health. 🍞

Digestive Support

Add 1 tablespoon ground flaxseed or 1 teaspoon psyllium husk powder to the dough for extra fiber. Flaxseed softens the bread slightly, while psyllium adds 7 grams of fiber per tablespoon—great for gut health.

Both options work best when mixed with the dry ingredients at the start. Store flaxseed in the fridge to preserve its omega-3 content, and always use freshly ground psyllium for maximum effectiveness.
