Ingredients for america's test kitchen garlic bread

Nine simple ingredients transform basic bread into golden, buttery perfection that shatters with every bite.

The baguette is non-negotiable here—crusty, fresh from the bakery is ideal, but even the day-old kind works if you toast it first. I always grab mine from Whole Foods or my local French bakery, but any good bakery section will have one. If you can't find a baguette, a long loaf of Italian bread in a pinch. The butter? Unsalted and cold—this is key for that perfect spreadable consistency. Don't skip the olive oil; it adds that restaurant-quality richness you can't get with butter alone.

No fresh garlic? Garlic powder at double the amount works in a pinch, but nothing beats fresh. The parsley is optional but adds that pop of color—fresh is best, but dried works too. If you're feeling fancy, add a pinch of red pepper flakes for a little kick. The flour might seem odd, but it helps create that crispy crust. Bob's Red Mill is my go-to for good quality flour. And trust me, freshly ground black pepper makes all the difference—pre-ground loses its punch fast.

This bread tastes even better the next day, so make extra. Store leftovers wrapped in foil at room temperature for up to 2 days—the crust stays crispy this way. For longer storage, freeze slices wrapped individually for up to 3 months. To reheat, pop in the oven at 350°F for 5-10 minutes until golden again. Pro tip: If you're prepping ahead, make the garlic butter mixture first and store it in the fridge for up to 3 days—just mix it with a fork before spreading.

Step-by-step instructions for america's Test Kitchen garlic bread

Here's the method that delivers that signature shatter-and-melt texture everyone loves.

In a medium saucepan, combine the 0.75 cup unsalted butter and 0.25 cup extra-virgin olive oil over low heat. Let it melt completely, then reduce heat to lowest setting—this keeps the butter from browning while still allowing the flavors to meld.

Add the 6 cloves minced garlic, 1 tsp garlic powder, 0.5 tsp dried oregano, 1.5 tsp salt, and 0.5 tsp black pepper. Stir constantly for 3-4 minutes until the garlic is fragrant but not browned. You'll see tiny bubbles form—the butter should smell like a garlic festival. Remove from heat and let cool for 5 minutes—this prevents the bread from getting soggy when you brush it later.

Place the whole sliced baguette on a baking sheet lined with parchment paper. Arrange the slices in a single layer, slightly overlapping if needed to fit. Brush both sides of each slice generously with the garlic butter mixture—you want it to look glossy, not just damp. The key here is to work quickly so the butter doesn't set.

Sprinkle the 1 tbsp all-purpose flour evenly over the top slices. This creates that signature crispy crust that shatters when you bite in. Don't skip this step—it's what makes this garlic bread stand out from the basic versions.

Preheat your oven to 375°F with a rack positioned in the middle. Slide the baking sheet into the oven and bake for 12-15 minutes until the edges are deep golden brown and the bread is heated through. You'll see the butter bubbling and the crust turning crispy—this is when you know it's ready.

Here's the thing—I like to broil for the last 1-2 minutes to get extra browning on top. Watch it closely so it doesn't burn. When the top is beautifully browned with crispy edges, remove from the oven immediately.

Let the garlic bread cool for 2-3 minutes—this gives the butter time to set slightly so it doesn't drip everywhere. While it's cooling, chop the 0.25 cup fresh parsley finely. Sprinkle it evenly over the top just before serving.

Slice diagonally for that classic presentation, and serve immediately. The bread should be hot, with layers that shatter when you cut through them, revealing that gooey, garlicky butter underneath. This is the kind of garlic bread that has people asking for seconds—and thirds.

Health benefits of this america's test kitchen garlic bread

Rich Butter Benefits

This garlic bread uses unsalted butter infused with olive oil for a perfect balance of richness and flavor. The butter provides healthy saturated fats that enhance flavor perception while contributing about 120 calories per serving—ideal for a satisfying side.

I always use European-style butter like Plugrá for its higher fat content and creamy texture. 🧈

Garlic’s Health Perks

The 6 cloves of fresh garlic in this recipe deliver allicin, a compound with proven anti-inflammatory and immune-boosting properties. Just one clove provides vitamin C and vitamin B6, while the garlic powder adds extra flavor without the pungency.

I find that mincing the garlic finely helps distribute its benefits evenly throughout each bite.

Fiber from Whole Grain

While this recipe uses a traditional baguette, opting for a whole grain or sourdough version boosts fiber content significantly. A single slice contains about 3-4 grams of fiber, supporting digestion and keeping you full longer.

The all-purpose flour sprinkle adds minimal carbs but creates that signature crispy texture that makes it irresistible. 🌾

Herbs for Antioxidants

Fresh parsley and oregano in this garlic bread contribute vitamin K and antioxidants that combat oxidative stress. The parsley adds vitamin C too, while oregano provides thymol, a compound with antimicrobial properties. I always use fresh herbs when possible—they make a noticeable difference in flavor and nutrition.

Balanced Sodium

The recipe uses 1.5 teaspoons of kosher salt, which is moderate for a side dish. This amount helps enhance all the flavors without overpowering them. If you're watching sodium intake, you can reduce it to 1 teaspoon while still maintaining great taste.

The salt also helps balance the richness of the butter and garlic. 🧂

Versatile Serving Options

This garlic bread serves as a complete meal on its own or pairs perfectly with soups, pasta, or grilled meats. The olive oil in the butter adds heart-healthy monounsaturated fats, while the black pepper provides a touch of piperine, which may enhance nutrient absorption from other foods.

It's a flavorful way to add nutrition to any meal! ✨
