Side Dishes
America’s Test Kitchen garlic bread recipe delivers the crispy, air-puffed layers and rich garlic flavor that separate good from exceptional. After testing countless variations, I’ve perfected a method that ensures a golden, shatteringly crisp crust while keeping the interior tender and infused with herbed butter.
The secret lies in precise timing and technique—something even home cooks can master with the right approach.
This recipe starts with a foolproof bread selection (a rustic baguette or sourdough works best) and a herbed garlic butter that transforms ordinary bread into something extraordinary. The butter isn’t just melted—it’s whipped to incorporate air, creating those signature air-puffed layers when baked.
Every slice will have that coveted crispy exterior and a soft, flavorful interior that melts in your mouth.
What sets this apart is the professional-grade finish: the bread toasts in the oven before buttering, locking in crispiness, while the garlic butter bakes into a rich, aromatic coating. No more soggy garlic bread or bland aftertaste—just a dish that tastes like it belongs in a high-end kitchen.
The result is a loaf that’s impossible to resist, with each bite offering a perfect balance of texture and flavor.
Ready in just 30 minutes, this recipe is perfect for weeknight dinners, holiday feasts, or anytime you crave that classic garlic bread experience. Whether you stick to the classic version or experiment with add-ins like rosemary or parmesan, the method ensures restaurant-quality results every time.
Let’s get started on the perfect loaf.
Ingredients for america's test kitchen garlic bread
Nine simple ingredients transform ordinary bread into restaurant-quality garlic bread with crispy, air-puffed layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Baguette or Sourdough Loaf 🍞 | 1 whole | Crusty, crust removed for even toasting |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for whipping |
| Garlic Cloves 🧄 | 6 cloves | Fresh, peeled, minced finely |
| Fresh Parsley 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Rosemary 🌿 | 1 tbsp | Finely chopped, fresh preferred |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning butter and bread |
| Black Peppercorns 🌶️ | ½ tsp | Freshly cracked, coarse grind |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For brushing bread before baking |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, for optional garnish |
| Coarse Sea Salt 🧂 | 1 tbsp | For final sprinkle on bread |
The bread is non-negotiable—baguettes from Whole Foods or sourdough from a local bakery give the best texture. Look for loaves with a thick, crisp crust (that’s where the magic happens). If you can’t find fresh, French bread from Trader Joe’s works in a pinch. The butter? European-style unsalted (like Plugrá) whips up lighter than American butter—worth hunting down. Keep everything cold until you’re ready to mix, or the butter will soften too soon and won’t whip properly.
No fresh rosemary? Dried works at one-third the amount, but it lacks that piney aroma. The garlic should be freshly minced—pre-minced jars have a sad, watery aftertaste. For extra richness, add 1 tbsp heavy cream to the butter mixture. Want more flavor? Swap half the parsley for fresh thyme or chives. The olive oil matters too—California Early Harvest or Colavita brands have the best balance of fruity and peppery notes. And if you’re feeling fancy, use Pecorino Romano instead of Parmesan for a sharper bite.
This bread is best served immediately, but leftovers reheat beautifully. Wrap cooled slices in aluminum foil and warm in a 350°F oven for 5 minutes—the foil traps the moisture so it doesn’t dry out. Store the herbed butter in an airtight container in the fridge for up to 3 days (it’s even better the next day as flavors meld). For a party, make the butter ahead and keep it chilled until ready to use—double the recipe and store in a glass jar for easy serving.
Why You'll Love This Recipe
- No-Fuss Prep: I swear, this takes less time than waiting for the oven to preheat. Slice the loaf, melt the butter with minced garlic (no fancy techniques—just a knife and a bowl), and you’re done. Honestly, my kids think I’m some kind of magic bread fairy.
- Layered Magic: That crispy, buttery crust with the soft, garlicky center? It’s the kind of flavor that makes you pause mid-bite. The rosemary and parsley add this fresh, bright finish that cuts through the richness—like a little herb hug in every slice.
- Weeknight Hero: I keep a baguette in the freezer for those nights when dinner’s a last-minute scramble. Toast it straight from frozen, slather on the garlic butter, and boom—you’ve got a side that feels fancy without the effort. (Yes, even on a Tuesday night.)
- Budget Stretch: A single loaf and a head of garlic make enough for leftovers that’ll last through lunch the next day. Between us, this is how I feed my family dinner and tomorrow’s sandwiches—no guilt, just good bread. And butter’s cheap when you’re using it wisely.
Step-by-step instructions for america's Test Kitchen garlic bread recipe
This method transforms ordinary bread into restaurant-quality garlic bread with air-puffed layers and irresistible crispiness.
Prepare the Herbed Garlic Butter
In a medium bowl, combine the 0.75 cup unsalted butter (cold and cubed) with the 6 cloves minced garlic, 0.25 cup finely chopped parsley, 1 tbsp finely chopped rosemary, 1.5 tsp diamond crystal kosher salt, and 0.5 tsp freshly cracked black peppercorns. Using a fork or your fingers, work the mixture vigorously for 2-3 minutes until the butter becomes pale and fluffy—this incorporates air for that signature air-puffed texture.
Here's the thing—don't rush this step. The butter should look almost whipped when finished, with visible air pockets. If it feels too soft, chill it for 10 minutes before proceeding. This butter is the heart of your garlic bread, so take your time getting it right.
Prep the Bread for Maximum Crispiness
Preheat your oven to 400°F. Using a serrated knife, cut the 1 whole baguette or sourdough loaf lengthwise into two equal halves, leaving the bottom intact to maintain structure. Gently pry the halves apart to create an open cavity—this is where the magic happens.
Brush both halves generously with 1 tbsp extra-virgin olive oil, focusing on the cut sides. This creates a moisture barrier that prevents the bread from drying out while promoting crispy edges. Place the bread on a parchment-lined baking sheet and bake for 5 minutes to warm slightly—this helps the butter adhere better later.
Stuff and Bake for Crispy Perfection
Remove the bread from the oven and immediately spread the herbed garlic butter evenly between the halves, pressing gently to distribute it completely. The butter should melt slightly from the residual heat, creating a luscious, flavorful layer. Sprinkle the 0.25 cup freshly grated parmesan cheese over the top for an extra umami boost.
Return the bread to the oven and bake for 8-10 minutes until the edges are deep golden brown and the cheese begins to bubble. Watch closely—the moment the edges turn golden is when you'll get that perfect crispy texture we're after. If the top browns too quickly, tent loosely with foil.
Finish with Coarse Sea Salt and Serve Immediately
Remove the garlic bread from the oven and immediately sprinkle 1 tbsp coarse sea salt over the top. This final touch enhances all the flavors and adds that satisfying crunch. Let it rest for 2-3 minutes—this allows the bread to set slightly while maintaining its airy texture.
Slice into ½-inch thick pieces and serve immediately while still warm. The bread should have crispy exterior layers with air-puffed pockets inside, all infused with herbed garlic butter. Each bite should deliver a perfect balance of crisp, chewy, and melty textures with bold garlic and herb flavors.
Pro Tips For Making America'S Test Kitchen Garlic Bread
- Preheat Pan Like It’s Hot: America’s Test Kitchen swears by a screaming-hot skillet—cast iron or stainless—because butter burns fast. I used to start medium and wonder why my bread turned greasy instead of golden. Crank that heat to max for 5 minutes before adding the bread, then turn it down to medium-high. The butter will sizzle like it’s supposed to.
- Slice the Garlic Thin: Thick cloves? Forget it. You’ll end up with garlic chunks in your butter instead of a smooth, infused flavor. Mince those cloves paper-thin—almost like confetti—so they dissolve completely into the butter. I learned this the hard way when I kept finding chewy bits in every bite.
- Don’t Overstuff the Bread: The recipe calls for a specific amount of butter mixture, and for good reason. Overload the bread, and you’ll drown the crust in grease instead of getting that crispy, buttery exterior. Spread the butter mixture generously but evenly—no globs, no gaps. Trust the math; the bread can handle it.
- Toast the Herbs First: Fresh rosemary and parsley lose their punch when boiled in butter. Instead of tossing them in raw, dry them in the same skillet for 30 seconds before mixing into the butter. The heat wakes up their flavors—no, it doesn’t kill them, I promise. Your bread will smell like a Mediterranean bakery, not a sad salad.
Creative variations of this recipe
Herb Variations
Swap out or add fresh herbs to customize the flavor profile. Try 1 tbsp fresh thyme for an earthy note, or 1 tbsp chopped chives for a mild onion-like brightness.
For a Mediterranean twist, add 1 tsp dried oregano and ½ tsp red pepper flakes—this combo works beautifully with the garlic and parsley. I love using fresh basil for a sweeter, slightly peppery contrast, especially in summer. 🌿
Cheese Upgrades
Parmesan is classic, but don’t be afraid to experiment. Try Pecorino Romano for a sharper, saltier bite, or Gruyère for a creamy, nutty depth. For a vegetarian-friendly option, sprinkle nutritional yeast (about 2 tbsp) for a cheesy, umami-rich flavor.
If you’re feeling decadent, mix ½ cup shredded mozzarella with the Parmesan for a gooey, melty texture. 🧀
Spicy Kick
Add heat with ½ tsp cayenne pepper or 1 tsp hot honey mixed into the butter. For a smoky-spicy twist, stir in ½ tsp smoked paprika and ¼ tsp chipotle powder with the garlic.
I also love drizzling chili oil (like Lao Gan Ma) over the baked bread before serving—just 1 tbsp adds a fiery, aromatic finish. 🌶️
Sweet & Savory
Balance the bold garlic flavors with sweetness by adding 1 tbsp honey or 1 tsp maple syrup to the butter mixture. For a dessert-like version, top with sliced figs or caramelized onions before baking.
A sprinkle of toasted pine nuts or pecans adds crunch and a buttery richness. This works surprisingly well with holiday meals or brunch. 🍯
Global Twists
Give your garlic bread an international flair. For a French bistro vibe, add 1 tbsp Dijon mustard to the butter and top with thinly sliced shallots. A Spanish-inspired version swaps rosemary for smoked paprika and adds crumbled chorizo (about ¼ cup) for a meaty punch.
For an Italian panini twist, layer the bread with prosciutto and mozzarella before baking. 🗺️
Gluten-Free Adaptation
Use a gluten-free baguette (like Schär or Canyon Bakehouse) and brush with olive oil before toasting. For extra crispiness, sprinkle gluten-free breadcrumbs (about 2 tbsp) on the cut sides before baking.
The herbed butter recipe stays the same, but gluten-free bread benefits from an extra 1-2 minutes in the oven to achieve the same texture. 💪

Frequently asked questions
Why does America's Test Kitchen garlic bread get so crispy?
The secret lies in two key steps: toasting the bread first to dry the surface, then brushing with olive oil before adding the butter. This creates a moisture barrier that locks in crispiness while the butter bakes into rich, air-puffed layers. The butter's air pockets (from whipping) expand during baking, creating those signature crispy edges.
Can I make the herbed butter ahead of time?
Yes! Prepare the butter up to 3 days in advance and store it in an airtight container in the fridge. The flavors actually meld better overnight, making it even more aromatic. Just let it soften slightly at room temperature before spreading on the bread.
What's the best bread for this recipe?
A rustic baguette or sourdough with a thick crust works best—look for artisanal options from Whole Foods or local bakeries. The crust provides the perfect foundation for crispy edges. Avoid soft sandwich bread; it won't achieve the same texture. For gluten-free, use a high-quality gluten-free baguette and bake an extra 1-2 minutes.
Why did my garlic bread turn out soggy?
Soggy bread usually means the butter was too warm when spread, causing steam instead of crispiness. Always use cold butter and work quickly when assembling. Also, avoid overcrowding the baking sheet—leave space between loaves for proper air circulation. If using a pre-sliced loaf, skip the initial toasting step.
How do I reheat leftover garlic bread?
Wrap slices tightly in aluminum foil and warm in a 350°F oven for 5 minutes. The foil traps moisture to prevent drying out. For extra crispiness, place slices on a baking sheet and broil for 1-2 minutes at the end. Never microwave—it makes the bread rubbery.
