Ingredients for joanna gaines hasselback potatoes

Four russets, one knife, and forty-five minutes transform ordinary potatoes into Joanna Gaines' signature crispy-edged masterpiece.

The russet potatoes are non-negotiable here—Idaho-grown russets have the perfect starch-to-moisture ratio for Hasselback technique. Whole Foods and Trader Joe's carry excellent selections, but any reputable grocery store's russets will work. Look for potatoes with smooth, unblemished skins and medium size (about 1.5 lbs each). The butter should be European-style unsalted like Plugrá or Kerrygold—higher fat content yields superior crispiness. Fresh garlic cloves should be firm with no green shoots, and the herbs must be vibrant green, not wilting.

No unsalted butter? European-style salted butter works in a pinch, but reduce the added kosher salt by half. Fresh rosemary and thyme are ideal, but dried herbs at one-third the amount suffice if fresh isn't available. The olive oil should be extra-virgin with noticeable peppery bite—California avocado oil is a great alternative. For the peppercorns, Tellicherry black pepper from Penzeys Spices delivers superior flavor. Pre-mincing the garlic saves time, but peeling and crushing whole cloves with a knife releases more flavor compounds.

Store whole russet potatoes in a cool, dark place for up to 2 weeks, but move them to the fridge 24 hours before roasting to prevent premature browning. Melted butter should be kept refrigerated in an airtight container for 1 month, while fresh herbs last 1 week wrapped in damp paper towels. The roasted potatoes reheat beautifully—425°F for 10 minutes restores crispiness. Portion leftovers immediately to maintain texture.

Step-by-step instructions for Joanna Gaines' Hasselback potatoes

Master the art of Hasselback potatoes with this foolproof method delivering crispy edges and fluffy centers every time.

Begin by preheating your oven to 425°F with the rack positioned in the center position. Wash the 4 whole Russet Potatoes thoroughly and pat them completely dry with paper towels—this step is critical for crispy edges. Place each potato on a cutting board and use a sharp chef's knife to make thin, even slices along the length of each potato, stopping about ¼ inch from the bottom. The slices should fan out like an accordion but remain attached at the base.

I recommend making the first slice slightly deeper than the others to create a natural handle for gripping. This technique prevents the potatoes from rolling around in the oven while allowing the steam to circulate between the layers. Arrange the sliced potatoes on a rimmed baking sheet, spacing them evenly so they don't touch each other.

In a small bowl, combine the 0.5 cup Unsalted Butter, 1.5 tsp Diamond Crystal Kosher Salt, 1 tbsp Fresh Rosemary, 1 tbsp Fresh Thyme, and 0.5 tsp Black Peppercorns. Use a fork to mash the herbs into the butter until you achieve a coarse, chunky texture with visible herb pieces. This mixture will infuse the potatoes with maximum flavor while creating that signature golden crust.

Spread the herb butter mixture evenly between the slices of each potato, using your fingers to gently press it into the crevices. The butter should melt slightly from your hands, which helps it adhere better to the potato surfaces. For even coverage, I like to make a second pass after the initial application, ensuring every exposed surface gets coated.

Drizzle 2 tbsp Extra-Virgin Olive Oil evenly over the potatoes, focusing on the exposed slices. The oil should glisten on the surfaces—this visual cue indicates proper distribution. Using a pastry brush, gently spread the oil over all the exposed potato surfaces, including between the slices. This basting technique creates an additional layer of crispiness that complements the herb butter.

Transfer the prepared potatoes to the preheated oven and bake for 30 minutes. After this initial baking period, rotate the baking sheet 180 degrees to ensure even browning. The potatoes should begin developing golden edges with slightly crispy textures at this stage, but they won't be fully cooked yet.

Remove the potatoes from the oven and increase the temperature to 450°F. Sprinkle the 4 cloves Garlic Cloves, minced, evenly over the potatoes. The high heat will quickly infuse the garlic flavor throughout the potatoes without burning it. Return the potatoes to the oven and bake for an additional 15-20 minutes, or until the edges are deeply golden brown and crispy to the touch.

Watch for the perfect moment when the edges are crispy but the centers remain tender when pierced with a fork. The total baking time should be approximately 45 minutes. Remove the potatoes from the oven and let them rest for 5 minutes before serving. This resting period allows the juices to redistribute, ensuring each bite is perfectly moist and flavorful.

Use a spatula to carefully transfer the Hasselback potatoes to a serving platter. The crispy edges should hold their shape while the centers remain fluffy and tender. Serve immediately while still warm, as the texture and flavor are at their peak. The aroma of roasted garlic and herbs will fill your kitchen, creating an inviting presentation that matches the delicious results.

Each slice should reveal layers of golden potato with crispy edges that contrast beautifully with the soft interior. The herb butter and garlic infuse every bite with rich, savory flavors that make these potatoes a showstopper for any meal. Pair with your favorite protein and fresh vegetables for a complete, restaurant-quality dinner.

Common mistakes when making your joanna gaines hasselback potatoes

Uneven Slicing

Consistent slicing is critical—uneven cuts mean some layers cook faster than others, leading to dry centers or overcooked edges. I use a sharp chef's knife and make thin, parallel cuts about ⅛ inch apart, stopping ¼ inch from the bottom.

If your slices vary in thickness, rotate the potato and adjust your grip for uniformity. A mandoline slicer (like the OXO Good Grips) can help, but practice makes perfect with freehand slicing. 🔪

Skipping the Dry

Wet potatoes steam instead of crisping. After washing, I pat each potato thoroughly with paper towels—even damp spots prevent browning. Skip the towel? You’ll end up with soggy edges. Pro tip: Let them air-dry on a rack for 10 minutes before slicing for extra insurance against moisture. 🌡️

Overcrowding the Pan

Potatoes touching each other trap steam, making edges limp instead of crispy. Space them ½ inch apart on a rimmed baking sheet—no overlapping! I use two sheets if needed. Overcrowding also causes uneven baking. A half-sheet pan (like Nordic Ware) gives the best airflow for even crisping. 🍽️

Underestimating Rest Time

Serving Hasselback potatoes immediately after baking causes them to collapse. The 5-minute rest lets juices redistribute, keeping centers fluffy. I’ve seen people skip this and end up with sad, flat slices. Use a spatula to transfer them to a platter—never stack them, or you’ll crush the layers. 🕒

Ignoring Temperature Swaps

Starting at 425°F then cranking to 450°F ensures crispy edges without burning. Staying at one temp risks undercooked centers or charred outsides. If your oven runs hot, reduce the initial temp to 400°F and monitor closely. An oven thermometer (like Thermoworks) is worth the investment for accuracy. 🌡️

Using Low-Quality Butter

Margarine or salted butter lacks the fat needed for crispy layers. Stick to European-style unsalted butter (like Plugrá)—it has 82% fat content, which is crucial. Salted butter works in a pinch, but reduce the added salt by ½ tsp to avoid over-salting.

Never substitute with oil-only mixtures; butter’s dairy solids create that signature crust. 🧈
