Mozzarella Stuffed Soft Pretzels

The smell of baking soda hitting boiling water still takes me back to my first apartment kitchen, where I learned that soft pretzels are basically magic. I'd attempted them before, but they always came out dense and bready. The moment I figured out that cheese could live inside them? My Sunday snack game changed forever.

I made these for a Super Bowl party a few years back and watched them vanish in under ten minutes. My friend Sarah stood by the cooling rack, eating them straight from the parchment paper with her bare hands, cheese stretching down to her elbow. Now she texts me every October asking when pretzel season is starting.

Ingredients

• 3 ½ cups all purpose flour: This amount creates the perfect dough consistency that holds its shape during the poaching process
• 1 packet active dry yeast: The leavening agent that gives pretzels their signature chew and rise
• 1 ½ cups warm water: Should feel like bath temperature to activate the yeast without killing it
• 1 tbsp granulated sugar: Feeds the yeast and helps the dough develop that gorgeous golden brown color
• 2 tsp fine sea salt: Essential for flavor and helps strengthen the gluten structure
• 2 tbsp unsalted butter melted: Adds richness and keeps the dough tender
• 8 sticks mozzarella cheese: String cheese works perfectly but cut your own from a block for thicker cheese lines
• 8 cups water and ½ cup baking soda: This bath creates that distinctive pretzel crust and deep flavor
• 1 large egg beaten: The egg wash gives the final bake that irresistible shiny finish
• Coarse salt: The finishing touch that makes them look and taste like authentic soft pretzels

Instructions

Wake up the yeast:

Dissolve the sugar in warm water and sprinkle yeast on top. Wait five minutes until you see a foamy layer on the surface, then stir in melted butter and salt.

Build the dough:

Gradually mix in flour until a shaggy dough forms, then knead on a floured surface for five to seven minutes until the dough feels smooth and springs back when poked.

Let it rise:

Place the dough in a greased bowl, cover, and leave it in a warm spot for about an hour until it has doubled in size.

Get your oven ready:

Preheat to 450°F and line two baking sheets with parchment paper so nothing sticks later.

Wrap the cheese:

Divide dough into eight pieces and roll each into an eighteen inch rope. Flatten slightly, lay a cheese stick down the center, and pinch the edges tight to seal completely before shaping into pretzels.

Create the pretzel bath:

Bring the water and baking soda to a boil in a large saucepan, then reduce to a gentle simmer.

Dip each pretzel:

Carefully lower one pretzel at a time into the bath for thirty seconds, then remove with a slotted spatula and place on the prepared baking sheets.

Add the finish:

Brush each pretzel with beaten egg and sprinkle generously with coarse salt.

Bake until golden:

Bake for twelve to fifteen minutes until deeply golden brown, brushing with melted butter right after they come out of the oven.

These have become my go to whenever someone needs comfort food. Something about pulling apart warm dough to find that surprise cheese center just makes people happy in a way that regular snacks never quite manage.

Getting That Perfect Shape

Shaping pretzels takes a little practice but I have found a method that works every time. Make a U shape with your dough rope, cross the ends over each other twice, then fold them down to press into the bottom curve. Do not worry if they look imperfect they still taste incredible.

Make Ahead Strategy

You can prepare the stuffed pretzels through the shaping step and refrigerate them on a parchment lined baking sheet overnight. Let them sit at room temperature for thirty minutes before the baking soda bath step. The dough will continue developing flavor while it rests.

Serving Suggestions

These shine alongside a bowl of warm marinara or a garlic butter dipping sauce. I also love setting up a toppings bar with crushed red pepper, garlic powder, and everything bagel seasoning so everyone can customize their own.

• Mix Italian herbs into the flour for a savory twist
• Try cheddar or pepper jack instead of mozzarella
• Freeze unbaked pretzels for up to a month and bake straight from frozen

Recipe FAQs

→ Can I make these pretzels ahead of time?

Yes, you can prepare the dough and shape the pretzels up to 24 hours in advance. Store them covered in the refrigerator on parchment-lined baking sheets. Let them come to room temperature for about 30 minutes before the baking soda bath and baking.

→ What other cheeses work well for stuffing?

While mozzarella provides classic melty goodness, you can substitute cheddar, pepper jack for a spicy kick, Swiss for nutty notes, or even brie for creamy luxury. Just ensure the cheese is firm enough to hold its shape during wrapping.

→ Why do pretzels need a baking soda bath?

The baking soda bath (lye bath) creates the pretzel's distinctive deep brown color, shiny crust, and characteristic slightly tangy flavor. This alkaline solution gelatinizes the surface starch, producing that classic chewy exterior and authentic bakery taste.

→ How do I prevent cheese from leaking during baking?

The key is sealing the dough tightly around the cheese stick. Pinch edges firmly together, ensuring no gaps exist. Shape carefully so the seams stay secure during the poaching step. Avoid overfilling—use standard string cheese size portions.

→ Can I freeze these pretzels?

Absolutely! Freeze baked, cooled pretzels in airtight bags for up to 3 months. Reheat in a 350°F oven for 5-7 minutes until warm and crisp. You can also freeze unbaked shaped pretzels after the baking soda bath—freeze solid on baking sheets, then transfer to bags, and bake directly from frozen, adding 2-3 minutes.

→ What's the best way to store leftover pretzels?

Store cooled pretzels in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. Reheat in a 350°F oven for 5-8 minutes to restore crispiness. Avoid microwaving, which makes them tough and chewy.
