Garlic Butter Mandoline Potatoes Drizzled with Date Molasses

This Garlic Butter Mandoline Potatoes Drizzled with Date Molasses dish, with its elegant presentation, features thinly sliced, mandoline-style potatoes, roasted in a cast-iron dish. It’s seasoned with simple herbs and spices, layered with sweet potatoes and onions, and baked in rich, roasted-garlic butter to create a crispy, smoky finish. A drizzle of sweet date molasses adds a Middle Eastern twist, bringing depth and balance. The result is a dish that delivers both the creamy texture, crisp edges, and subtle sweetness you’re craving.

This show-stopping cast-iron mandoline potato dish features a beautiful spiral design that will have everyone stopping to grab a bite, especially if you bring it to a dinner party or host one yourself!

I’ve baked mandoline potatoes in the past using standard baking dishes, but baking them in a cast-iron skillet is a whole new level. It creates a smoky aroma and roasts the potatoes to perfection. Don’t be intimidated by the effort needed to create this spiral design. It’s actually quite simple! All you need to do is slice your potatoes on level 3 using a mandoline slicer and alternate them as you go to build that stunning pattern.

If you don’t own a mandoline slicer, no worries. With a sharp knife and solid slicing skills, you can still achieve this look; it just takes a bit more patience and attention to detail.

Here’s a quick tip to keep everything looking aligned: use larger potato slices for the outer layer of your swirl and smaller slices toward the center. Work your way around the cast-iron skillet, then add your onions at the end, tucking them in tightly to help hold everything in place. Fill in any gaps with extra pieces to keep the potatoes snug.

Finally, sprinkle with salt, then crinkle a piece of parchment paper, run it under water, and place it over the potatoes. Wet parchment paper helps retain moisture, ensuring the potatoes cook evenly without drying out or burning on top.

Why I love this dish so much…

This dish is a great alternative to cast-iron Hasselback potatoes and is perfect for brunch, lunch, or even dinner! I also used the leftovers the next day for breakfast, making a delicious omelette. It’s so versatile that it’s perfect to make once a week as a meal prep option.

It’s also great for vegetarians and can easily be made vegan by swapping the butter for a plant-based alternative.

The best part about this dish is that you can drizzle just about anything over it! I love a touch of sweetness with my savory dishes, so I used date molasses. But you can skip that and keep it fully savory. Try adding a sprinkle of crispy bacon pieces or drizzling it with a feta cream dressing. Just about anything works with this dish; that’s what makes potato dishes so great!

STEPS TO MAKE THIS RECIPE!

Step 1: Prep the Potatoes
Preheat your oven to 380°F (193°C). Fill a large bowl with cool water, then add salt and a pinch of baking soda. Peel your potatoes, leaving one sweet potato unpeeled for a nice visual contrast later. Set your mandoline slicer to level 3 and slice the potatoes, placing them directly into the bowl of water as you go.

Step 2: Prep the Onions
Slice your onions into pieces about ½ inch thick, keeping the layers intact. Set aside.

Step 3: Season the Potatoes
Drain the potatoes well, then transfer them to a bowl. Add olive oil and your desired seasonings, and toss until evenly coated.

Step 4: Infuse the Butter
Place your cast-iron skillet over high heat (or over an open flame). Melt the butter, then add 2 tablespoons of olive oil and the garlic cloves. Cook until the garlic becomes golden and fragrant.

Step 5: Build the Spiral
Remove from heat. Begin stacking your potato slices with large slices forming the outer layer first: layer about 4–5 slices of russet potato, followed by 3 slices of sweet potato, including some with the skin for visual appeal. Arrange the stacks in a circular pattern around the skillet until it’s filled. Use smaller slices toward the center, following the same pattern.

Step 6: Add Onions & Bake
Take your sliced onions (keeping the layers together) and tuck them between the potato stacks. Lightly sprinkle salt over the top, then distribute the roasted garlic around and on top of the potatoes.

Crumple a piece of parchment paper, run it under water, and place it over the potatoes, tucking in the edges. Bake for 35 minutes.

Remove the parchment paper and bake for another 15–20 minutes, until the edges turn golden and rotate.

Optional: Broil for 5–10 minutes for a crispier top. (Keep an eye on this step – it can burn if you don’t watch!)

Let it cool slightly, then serve with Date Molasses and enjoy!
