Ultimate Garlic Bread with Mozzarella and Parmesan Step-by-step instructions

Before you start

Before starting, roast the garlic: cut the top off the head, drizzle with oil, wrap in foil, and bake at 425°F (220°C) for about 30 minutes until soft. Let it cool, then squeeze the cloves out. Soften the butter by leaving it at room temperature for 30 minutes.

Chop the parsley and grate the parmesan if not already grated. Have the shredded mozzarella and cheddar measured and ready. Preheat the broiler to 425°F (220°C) and line a baking sheet with parchment or foil for easy cleanup.

Instructions

Roast and Mix

1. 1Roast the Garlic and Make the Butter
   Heat the oven to 425°F (220°C). Cut the top off the garlic head to expose the cloves, drizzle with a little oil, wrap in foil, and roast for about 30 minutes until soft. When cool enough to handle, squeeze the cloves into a bowl. Add the softened butter, parsley, parmesan, and sea salt. Mash with a fork until smooth and well combined.
   Look for The butter should be spreadable and fragrant, with visible flecks of parsley and parmesan.
   Tip Roast the garlic ahead of time and store in the fridge for up to a week.
2. 2Slice the Bread
   Slice the French bread loaf in half horizontally, creating two long halves. Place them cut-side up on a baking sheet.
   Look for The bread should be cut evenly so both halves have a flat surface for the topping.
   Tip Use a serrated knife to slice through the crust without crushing the crumb.

After this phase, the garlic should be soft and caramelized, with a sweet aroma. The butter mixture should be smooth, spreadable, and evenly tinted with parsley and parmesan. Taste it: it should be savory, garlicky, and slightly salty. If the butter is too firm, let it sit at room temperature to soften before spreading.

Assemble

3. 3Slather the Garlic Butter
   Spread the garlic butter generously across the cut surface of both bread halves, going edge to edge. Make sure to cover every bit of exposed crumb so the bread is well flavored.
   Look for The butter should coat the bread in an even layer, with no dry spots.
   Tip If the butter is too firm, let it sit at room temperature for a few minutes.
4. 4Add the Cheese Topping
   Pile the shredded mozzarella and cheddar on top of the buttered bread, spreading it out to cover the surface evenly. Press the cheese lightly so it adheres.
   Look for The cheese should cover the bread completely, with a few mounds for extra browning.
   Tip Use a mix of cheeses for a more complex flavor; the cheddar adds a sharp note.

The bread halves should be evenly coated with butter, edge to edge, with no dry spots. The cheese should cover the surface completely, with a few thicker mounds for extra browning.

The bread should look inviting, with the cheese piled high and the butter peeking through. Check that the baking sheet is ready and the broiler is hot.

Broil and Serve

5. 5Broil Until Bubbly and Golden
   Place the baking sheet in the oven and broil at 425°F (220°C) for about 8 minutes, watching closely, until the cheese is bubbly and golden with toasted brown spots. The edges of the bread should be crisp and the cheese fully melted.
   Look for The cheese will blister and bubble, and the bread edges will turn deep golden brown.
   Tip Broiling times vary; check at 6 minutes to avoid burning.
6. 6Pull Apart and Serve
   Remove the bread from the oven and let it cool for a minute or two. Pull apart a slice to reveal the long cheese stretch. Serve warm, pulling pieces apart as desired.
   Look for The cheese should stretch in long ribbons when pulled, with steam rising from the bread.
   Tip Serve immediately for the best cheese pull and crisp texture.

The cheese should be bubbling and golden, with blistered spots and a crisp edge. The bread should be toasted and crunchy on the outside, soft inside. When pulled apart, the cheese should stretch in long ribbons. The aroma should be rich and garlicky. Serve immediately while the cheese is hot and stretchy.

Common mistakes

One common mistake is using too much butter, which can make the bread soggy. Spread a generous but even layer, not a thick pool. Another is over-broiling; watch closely because the cheese can go from golden to burnt in seconds.

Also, avoid using pre-shredded cheese that doesn't melt well; shred your own for the best texture. Finally, don't skip roasting the garlic—it's the key to the deep flavor.

How to tell it’s done

The bread is done when the cheese is fully melted and bubbly, with golden brown spots and slightly blistered areas. The edges of the bread should be crisp and deeply golden. The cheese should be hot and stretchy, not just warm.

If the cheese is browning too quickly, move the bread to a lower oven rack. There is no protein in this recipe, so no internal temperature check is needed; rely on visual cues.
