Acme Bread Recipe: Foil-Sealed Crust With Chewy, Golden Crunch

This Acme bread recipe delivers the perfect balance of a foil-sealed crust so crispy it crackles with every bite and a chewy interior that practically melts in your mouth. 🔥 The secret lies in a precise blend of high-gluten flour and a controlled baking technique that creates that signature golden crunch without burning the exterior.

I've perfected this method over years of baking, and it never fails to impress—whether you're serving it with soup, sandwiches, or simply enjoying it warm from the oven.

The dough comes together with just five simple ingredients, but the magic happens during the two-hour proofing and the foil-sealing technique during baking.

This isn't your average bread recipe—it's designed to give you that restaurant-quality texture at home, with a crust so crisp it stands up to even the heartiest toppings. The key is patience: letting the dough rise slowly develops deep flavor, while the foil-sealing traps steam for an airy crumb.

What you'll end up with is a loaf that's golden brown on the outside and tender yet chewy inside, with a satisfying crackle that announces its arrival.

The aroma alone will have everyone gathering around the table, and the first bite delivers that perfect contrast of textures—crispy, chewy, and soft all at once. This isn't just bread; it's the kind of loaf that elevates any meal.

Best of all, this recipe scales perfectly for gatherings, freezes beautifully for later, and comes together in just under 6 hours of active and inactive time.

Whether you're a seasoned baker or just starting out, the step-by-step instructions will guide you through every phase—from mixing to baking—to achieve that foolproof Acme-style loaf every single time.

Ingredients for acme bread

Five ingredients, two hours of magic—this is how you make Acme-style bread with that legendary foil-sealed crust.

The high-gluten flour is non-negotiable here—it's what gives you that signature chewy interior and crispy crust. King Arthur or Cape Cod Mills are my go-tos, but any bread flour with 12-14% protein will work. The yeast? Saf-Instant dissolves directly in the water (no waiting for it to bloom), which saves time. For the butter, European-style if you can find it—it's higher in fat content and gives better flavor. The warm water should be 110°F—too hot and you'll kill the yeast, too cold and it won't activate properly. I always check with my finger—it should feel like bath water.

No high-gluten flour? All-purpose plus 1 tbsp vital wheat gluten gets you close. Short on instant yeast? Active dry yeast works too—just dissolve it in warm water first and wait 5 minutes for it to foam. The butter can be swapped for olive oil if you're avoiding dairy, though the flavor will shift slightly. For the foil-sealing technique, heavy-duty aluminum foil is key—it needs to hold its shape during baking. If you're making this for a crowd, double the recipe but use two loaf pans instead of one giant one for even baking. The cornmeal? Any fine grain works—just enough to prevent sticking.

This dough is a beast, so cover it with a damp towel and let it rise in a warm spot—75-80°F is ideal. If your kitchen is cold, toss it in the oven with the light on for extra warmth. The proofed dough keeps for 24 hours in the fridge if you want to bake it later. For freezing, shape the dough, wrap tightly in plastic, and freeze for up to 3 months. When ready to bake, thaw overnight in the fridge. The foil-sealed loaf reheats beautifully—5 minutes at 350°F brings back that crispy crust. Store leftovers in a bread box for up to 5 days—it's worth the investment.

Step-by-step instructions for foil-sealed artisan bread

Here's how to craft that signature Acme crust—chewy interior, golden crunch, and sealed-in steam for maximum flavor.

In a large bowl, whisk together the 1.5 cups warm water (tested at 110°F—too hot kills yeast), 1 tbsp granulated sugar, and 2.5 tsp instant yeast. Let sit for 5 minutes until frothy—this confirms your yeast is alive and ready to work. If it doesn't bubble, start over with fresh yeast.

Add the 5 cups high-gluten bread flour and 2 tsp salt, then mix with a wooden spoon until a shaggy mass forms. The high gluten content means this dough will be stickier than all-purpose flour—don't fight it. Press the dough together, then knead by hand for 8-10 minutes until smooth and elastic. You're building gluten strands that will give your bread that signature chewy texture.

Cut the 0.5 cup cold, cubed unsalted butter into the dough and knead for another 5 minutes until fully incorporated. The cold butter creates pockets of fat that will melt during baking, creating that irresistible golden crust while keeping the interior tender. If the dough feels too sticky, wet your hands slightly—this prevents tearing when handling.

Shape the dough into a round loaf and place it in a lightly greased bowl. Cover with a damp towel and let rise at room temperature for 1 hour. You'll see it nearly double in size—this first rise develops flavor and structure. For best results, keep your kitchen at 75°F or warmer; cooler temps slow fermentation.

Punch down the risen dough and shape it into a 12-inch round loaf on a parchment-lined baking sheet. Dust the top generously with 0.25 cup cornmeal—this creates a barrier that prevents sticking when you flip it later. Let the shaped loaf rest for 15 minutes while you preheat your oven to 425°F.

Here's the Acme secret: Cut a 12x12-inch square from the aluminum foil and place it on the counter. Flip the dough onto the foil, seam-side up, then carefully fold the foil up the sides to create a sealed baking chamber. This traps steam during the initial bake, creating that signature crust while keeping the interior moist. Poke a few small holes in the top for steam to escape.

Bake the foil-sealed loaf for 25 minutes at 425°F. The trapped steam will create a dramatic oven spring—watch as the loaf puffs up dramatically. After 25 minutes, remove the foil and immediately sprinkle the top with 1 tsp coarse sea salt. Return to the oven for 10-15 minutes until the crust turns a deep golden brown.

You'll know it's done when the internal temperature reaches 190-195°F and the crust has that beautiful crackly texture. The bottom should be golden brown with a slight char in spots—this is where the magic happens. If the top browns too quickly, tent with foil for the last few minutes to prevent burning.

Remove the bread from the oven and let it cool on a wire rack for at least 30 minutes before slicing. This resting period allows the gluten to relax and the crumb to set properly. The longer you wait (up to 2 hours), the more flavor develops as the starches convert.

For serving, slice with a serrated knife and listen for that satisfying crack—the hallmark of a perfect Acme crust. The interior should be chewy with an open crumb structure, while the exterior delivers that irresistible golden crunch. Store wrapped at room temperature for 3 days or freeze for up to 3 months to preserve freshness.

Dietary considerations for this recipe

Gluten-Free Adaptation

For a gluten-free version, replace the 5 cups high-gluten bread flour with a 1:1 gluten-free bread flour blend like King Arthur Measure for Measure or Bob's Red Mill 1-to-1. Add 1 tsp xanthan gum to help mimic the chewy texture.

The yeast activation and hydration ratios stay the same, but expect a slightly denser crumb. Proofing may take 10-15 minutes longer due to reduced gluten elasticity. 🌾

Dairy-Free Option

Swap the 0.5 cup unsalted butter for 0.5 cup olive oil or dairy-free margarine (like Miyoko's). The oil won't create the same pockets as butter, so the crust will be slightly less crisp, but the interior remains tender.

For extra flavor, add 1 tsp garlic powder to the dough. Bake with the foil seal as directed—just monitor closely for browning since oils can darken faster. 🧈

Low-Carb/Keto

Transform this into a keto-friendly loaf by replacing flour with 3 cups almond flour and 2 cups psyllium husk powder (for binding). Reduce water to 1 cup and omit sugar entirely. The dough will be dry and crumbly—mix with wet hands and knead briefly to form a shaggy mass.
