Crispy Sliced Potatoes with Seasoned Olive Oil are the kind of side dish that makes a plain dinner feel planned. The potatoes fan open in the oven, the edges brown, and the centers stay soft enough to pull apart with a fork.
I like this version because it uses pantry spices and olive oil instead of butter or cheese. You still get deep color and crisp edges, but the potato itself stays the main thing.
Crispy Sliced Potatoes with Seasoned Olive Oil
The ingredient list is short, so each piece matters. Choose firm russet potatoes with dry, unbroken skins, and use fresh spices since paprika and garlic powder fade fast in the pantry.
- Russet potatoes. Their starchy flesh turns fluffy inside while the thin cut edges crisp in the oven.
- Olive oil. Carries the spices into the slices and helps the surface brown.
- Smoked paprika. Adds warm color and a gentle roasted flavor.
- Garlic powder. Gives steady savory flavor without bits of fresh garlic burning.
- Onion powder. Rounds out the seasoning and makes the potatoes taste fuller.
- Cayenne pepper. Adds a small background heat. Use less if you want a milder side.
- Fine salt. Seasons evenly and slips between the thin cuts.
- Black pepper. Adds a sharp finish that balances the oil.
- Fresh parsley. Brings color and a clean finish after baking.
Slice, Brush, Bake
- Heat the oven. Set the oven to 425°F and line a baking sheet with parchment. The hot start helps the cut edges brown before the centers dry out.
- Prep the potatoes. Scrub the potatoes and dry them well. Put chopsticks on both sides of one potato, then slice thin cuts across the top without cutting through the base.
- Mix the oil. Stir olive oil, smoked paprika, garlic powder, onion powder, cayenne, salt, and pepper in a small bowl until the spices are evenly suspended.
- Season the cuts. Brush the potatoes all over with the seasoned oil. Gently open the slices with your fingers so some oil drips between them.
- Bake until tender. Bake for 35 minutes, then brush with the remaining oil from the bowl. Keep baking for 10-15 minutes until the edges are crisp and a knife slides into the center.
- Finish and serve. Sprinkle with parsley and a little extra salt while hot. Let them sit for 3 minutes so the surfaces firm up before serving.
The Slice Thickness Matters
Aim for cuts about 1/8 inch apart. Thinner slices give you more crisp edges, but they also cook faster, so check early if your potatoes are small. If the slices are much thicker, the potatoes will still taste good, but they eat more like a standard baked potato.
The easiest guide is a pair of chopsticks or wooden spoon handles. Set one on each side of the potato and let the knife stop against them. This gives you a steady base and keeps the potato from splitting into loose coins.
Seasoning That Actually Clings
Mix the spices into the olive oil before brushing. Dry seasoning sprinkled over the top lands in patches, while seasoned oil runs between the cuts and coats more surface area. If you like a steakhouse-style side, this same paprika and garlic profile feels close to Sliced Baked Potatoes Longhorn.
Do not be shy with the brush. The goal is not a greasy potato, but each cut should look lightly glossy before it goes into the oven. For a richer variation, try the garlic-heavy direction from roasted garlic butter potatoes and add minced roasted garlic after baking.
Getting Deep Golden Edges
Use a large baking sheet and leave space between the potatoes. Crowding traps steam, and steam is the enemy of crisp edges. Bake on the middle rack first so the centers soften, then move the tray to the upper third for the last few minutes if you want darker tips.
A second brush of oil halfway through baking helps a lot. The potato slices open as they soften, which gives you a chance to season the new surfaces. For nutrition estimates on raw potatoes and olive oil, I use the searchable data at USDA FoodData Central as a starting point.
Easy Swaps And Add-Ons
Use sweet paprika for a milder flavor or smoked paprika for a deeper one. A pinch of dried rosemary, thyme, or Italian seasoning works well, but crush dried herbs between your fingers so they do not sit in hard flakes on top.
For a cheesy finish, sprinkle parmesan during the final 8 minutes of baking. For a brighter side, finish with lemon zest and parsley. If you want another crisp potato idea for a dinner spread, Crispy Stacked Potatoes gives you a layered version with a different texture.
Serving And Storing
Serve these potatoes with roasted chicken, grilled steak, salmon, or a big salad. They are also good with a cool dip. Try sour cream with chives, Greek yogurt with lemon, or a smoky aioli.
Leftovers keep in the fridge for up to 3 days in an airtight container. Reheat them in a hot oven or air fryer so the edges wake back up. For general leftover timing, the FoodSafety.gov cold storage chart is a useful reference. For a creamy potato side on another night, save Creamy Mashed Potatoes with Roasted Garlic and Parmesan.
Summary
These sliced baked potatoes are simple, budget-friendly, and easy to season differently each time. Serve them hot from the oven while the edges are still crisp.
FAQs
- What potatoes work best for crispy sliced potatoes?
Russet potatoes work best because they bake up fluffy in the center and crisp nicely around the cut edges. Yukon gold potatoes also work, but they will be creamier and a little less crisp.
- How do I slice the potatoes without cutting through?
Place a chopstick or wooden spoon handle along each side of the potato before slicing. The knife will hit the guides before it reaches the cutting board, which keeps the bottom intact.
- Can I use a different oil?
Yes. Avocado oil works well if you want a more neutral flavor. Regular olive oil is also fine, but extra virgin olive oil gives the seasoning a fuller taste.
- Can I make these potatoes ahead?
They are best right after baking. You can slice the potatoes a few hours ahead and keep them covered in cold water, then dry them very well before oiling and baking.
- How should I reheat leftovers?
Reheat leftovers on a baking sheet at 400°F for 10-15 minutes. The microwave warms them, but it softens the crisp edges quickly.
- Why are my sliced potatoes not crisping?
They may be too wet, too crowded, or under-oiled. Dry the potatoes after washing, leave space on the tray, and brush oil into the cuts so the hot air can brown the edges.
