Potato Focaccia Recipe: Fluffy Olive Oil Bread With Crispy Edges

This potato focaccia recipe transforms humble ingredients into a fluffy, crispy-edged bread that steals every meal. The secret lies in blending tender mashed potatoes into the dough, creating a texture that's impossibly light yet sturdy enough to hold dimples and olive oil pools.

I perfected this version after years of experimenting with yeasted doughs—where the potato transforms a basic focaccia into something truly special.

The beauty of this recipe is its foolproof technique: no fancy equipment, just a bowl, a baking sheet, and patience. The potatoes add moisture and structure, preventing a dry crumb while giving each bite a subtle, earthy sweetness.

Olive oil infuses the dough during proofing, creating that signature golden crust with crispy edges that flake perfectly. This method ensures restaurant-quality results without the complexity.

By the time it emerges from the oven, you'll have a focaccia with golden-brown dimples, crispy edges that shatter between your fingers, and a tender interior that's impossible to resist.

The aroma alone will have everyone gathering around your table. Serve warm with olive oil for dipping or pair it with soups and salads for a hearty, satisfying side.

For those who want to elevate it further, consider adding rosemary leaves during the final proof or sprinkling grated parmesan before baking. The possibilities are endless, but the foundation—potatoes, olive oil, and proper technique—is what makes this focaccia unforgettable. Let's get started on creating your perfect loaf.

Ingredients for potato focaccia

Transform humble pantry staples into restaurant-quality focaccia with this potato-infused dough recipe.

The Russet potatoes are the foundation—peeled and boiled until fork-tender—they infuse the dough with moisture and subtle sweetness. Store-bought russets work fine, but organic varieties often have fewer blemishes. For optimal texture, avoid pre-shredded potatoes (they contain anti-caking agents that alter hydration). The extra-virgin olive oil should be Italian or Spanish—brands like Bertolli or Colavita deliver consistent quality. Freshly ground rosemary elevates the aroma, but dried works at one-third the amount if needed. Diamond Crystal kosher salt dissolves cleanly, unlike table salt which can leave grainy residue.

No yeast on hand? Instant yeast works at the same ratio, but active dry yeast requires the warm water activation step. Substitute whole wheat flour by replacing one cup all-purpose with whole wheat, though texture will be denser. Out of rosemary? Swap for thyme or oregano at the same quantity. The coarse sea salt for dimples should be Maldon or Jacobsen—their flaky texture creates perfect craters. Room-temperature egg integrates better, but cold works if you're in a rush. Parmesan cheese adds umami depth, but Pecorino Romano works equally well when freshly grated.

Store unbaked dough in an airtight container for up to 24 hours in the fridge—let it warm to room temperature before shaping. Freshly baked focaccia keeps at room temperature for 2 days, wrapped in a clean kitchen towel. For longer storage, slice and freeze portions for up to 3 months. Reheat slices in a 350°F oven for 5-7 minutes to restore crispness. The olive oil pools solidify when cold—brush with fresh oil before serving for maximum flavor impact.

Step-by-step instructions for potato focaccia recipe

Transform simple ingredients into a golden, crisp-edged focaccia with a tender potato-infused interior.

Begin by boiling the 2 lbs russet potatoes in their skins until fork-tender, about 20-25 minutes. Drain immediately and return them to the pot. Add the 0.75 cup extra-virgin olive oil and mash until completely smooth—no lumps should remain. This olive oil-infused purée becomes the heart of your focaccia, ensuring rich flavor and moist texture.

While still warm, season the purée with 1.5 tsp diamond crystal kosher salt and let it cool to room temperature. The potatoes should form a thick, velvety base that will later incorporate into the dough. Real talk: Skipping this step means missing the signature moistness that sets this focaccia apart from traditional versions.

In a separate bowl, combine the 0.25 oz active dry yeast with the 1 tbsp granulated sugar and 1 cup warm water (110°F). Let it sit for 5-7 minutes until frothy—this confirms the yeast is alive and ready to work. If it doesn't bubble, your focaccia will fail to rise properly.

In a stand mixer fitted with a dough hook, combine the cooled potato purée with the 3.5 cups all-purpose flour. Add the yeast mixture and mix on low speed until just combined. Increase to medium speed and knead for 5 minutes until the dough becomes smooth and elastic. This kneading develops gluten, which creates the focaccia's signature airy texture.

Add the 1 whole large egg and mix until fully incorporated. The dough should pull away from the sides of the bowl and form a cohesive mass. Stir in the 0.25 cup chopped fresh rosemary and the 0.5 cup freshly grated parmesan cheese. The rosemary adds aromatic depth, while the parmesan contributes a subtle umami richness that pairs perfectly with the potatoes.

Transfer the dough to a lightly oiled bowl, cover with a damp towel, and let it rise in a warm place for 1-2 hours, or until doubled in size. Here's the thing—don't rush this step. A slow rise allows the gluten to relax and the flavors to meld, resulting in a lighter, more flavorful focaccia.

Generously grease a 9x13-inch baking pan with additional extra-virgin olive oil. Transfer the risen dough to the pan and shape it gently to fit, using oiled hands to press it evenly. Poke dimples all over the surface with your fingers or a fork—this creates pockets for the olive oil to pool and crisp during baking.

Cover the pan with a towel and let the dough rise again for 30-45 minutes until it's puffy and nearly fills the pan. The edges should look slightly rounded, and the dimples should have deepened. This second rise is critical—it ensures the focaccia will have that signature tall, airy structure rather than a flat, dense texture.

Preheat your oven to 425°F. Drizzle the dough liberally with the remaining olive oil, then sprinkle evenly with the 2 tsp coarse sea salt and 1 tbsp flaky sea salt. Bake for 25-30 minutes until the edges are deep golden brown and the top is crispy. The focaccia is done when it sounds hollow when tapped on the bottom.

Remove from the oven and let it cool for 5 minutes before slicing. The interior should be tender and infused with potato flavor, while the exterior should be crackly and crisp. Serve warm, ideally within the first hour when the texture is at its peak. This focaccia holds its crispness for about 2 hours, but the flavor is best enjoyed fresh from the oven.

Pro cooking tips for perfect results

Dough Temperature Control

The secret to a light, airy focaccia lies in keeping your dough at 75-78°F during mixing and kneading. I use a kitchen thermometer to check the potato purée before adding flour—it should be just warm to the touch, not hot.

Cold dough struggles to rise properly, while warm dough activates yeast too quickly. If your kitchen is chilly, place the mixing bowl on top of your oven with the light on to create gentle warmth. This balance ensures even gluten development without overworking the dough. 🌡️

Olive Oil Infusion

Don’t skimp on the extra-virgin olive oil—this is what creates those signature golden pools and crispy edges. I recommend using Bertolli Intenso for its robust flavor, but any high-quality Italian oil works. Brush the dough generously before baking and again immediately after removing from the oven.
