Follow these detailed steps carefully to ensure your homemade breadsticks turn out perfectly fluffy, cheesy, and delicious every time. The process is broken down into dough preparation, rising, and baking.

Step 1: Activate the Yeast (Proofing)
In a large mixing bowl or the bowl of a stand mixer, combine the warm water and granulated sugar. Stir gently until the sugar is mostly dissolved. Sprinkle the active dry yeast over the surface of the water. Let it sit undisturbed for 5-10 minutes. You’ll know the yeast is active and ready when the mixture becomes foamy and bubbly on top. If it doesn’t foam, your yeast may be old or the water temperature was incorrect; you will need to start over.

Step 2: Form the Dough
Once the yeast is activated, add the olive oil, salt, and about 3 cups of the all-purpose flour to the bowl. If using a stand mixer, attach the dough hook and mix on low speed until a shaggy dough begins to form. If mixing by hand, use a wooden spoon to stir everything together.

Step 3: Knead the Dough
Continue to mix on low-medium speed, gradually adding the remaining ½ cup of flour until the dough pulls away from the sides of the bowl. The dough should be soft and slightly tacky, but not overly sticky. If it’s too sticky, add a tablespoon of flour at a time. Knead the dough for 6-8 minutes with the stand mixer, or transfer it to a lightly floured surface and knead by hand for 8-10 minutes. The goal is to develop the gluten, which will make the breadsticks chewy and structured. The finished dough should be smooth and elastic.

Step 4: First Rise
Lightly grease a large, clean bowl with a bit of olive oil. Form your kneaded dough into a smooth ball and place it in the bowl, turning it over once to coat the top with oil. This prevents a dry crust from forming. Cover the bowl with plastic wrap or a damp kitchen towel. Place it in a warm, draft-free spot to rise for 60-90 minutes, or until the dough has doubled in size.

Step 5: Shape the Breadsticks
Grease a 9×13-inch baking pan with butter or non-stick spray. Gently punch down the risen dough to release the air. Transfer the dough to the prepared baking pan. Using your fingertips, gently press and stretch the dough until it evenly covers the bottom of the pan. Don’t worry if it’s not perfect; it will even out as it rises again.

Step 6: Second Rise
Cover the pan with plastic wrap or a damp towel and let the dough rest for a second, shorter rise of about 20-30 minutes. While the dough is resting, preheat your oven to 400°F (200°C).

Step 7: Prepare the Topping
In a small bowl, combine the melted butter, minced garlic, Italian seasoning, ½ teaspoon of salt, and black pepper. Stir well to create your garlic butter mixture.

Step 8: Top the Dough
After the second rise, uncover the dough. Using your fingers or the handle of a wooden spoon, press dimples all over the surface of the dough. This creates little pockets to hold the delicious garlic butter. Brush the entire surface of the dough evenly with the garlic butter mixture, making sure to get it into all the dimples. Sprinkle the shredded mozzarella cheese evenly over the top, followed by the grated Parmesan cheese.

Step 9: Bake to Golden Perfection
Place the pan in the preheated oven and bake for 20-25 minutes. The breadsticks are done when the top is deeply golden brown, the cheese is completely melted and bubbly, and the edges are slightly crispy.

Step 10: Garnish and Serve
Remove the pan from the oven and let it cool for about 5 minutes. This allows the cheese to set slightly, making it easier to cut. Sprinkle the chopped fresh parsley over the top for a fresh finish. Use a pizza cutter or a sharp knife to slice the bread into 12-16 individual sticks. Serve immediately while warm and gooey.
