Introduction

Right away, Oven Baked Potato Slices fill the room with that toasty, garlicky scent that says “sit down and relax.” This always takes me back to Sunday dinners.

Ingredients You’ll Need
- 4 medium yellow potatoes, scrubbed (not peeled)
- 3 tablespoons olive oil
- ¼ teaspoon garlic powder
- ¼ teaspoon onion powder
- ¼ teaspoon black pepper
- ½ teaspoon dried parsley
- ½ teaspoon salt, or to taste
- 4 tablespoons shredded Parmesan cheese, divided
Chef notes:
- Use waxy yellow potatoes for creamier centers.
- A mandoline gives even slices; slice carefully.
- Fresh garlic = bigger flavor.
How to Make It
- First, preheat your oven to 450°F (232°C) and line a rimmed baking sheet with parchment paper so cleanup stays easy.
- Then, using a mandoline or a sharp knife, slice the potatoes into ¼-inch thick rounds; you want uniform pieces for even browning.
- Next, place the slices in a large bowl and add olive oil, garlic powder, onion powder, pepper, parsley, salt, and 2 tablespoons Parmesan. Toss until every round glows with oil and seasoning.
- Arrange the slices in a single layer on the prepared sheet; avoid overlapping so each one crisps.
- Bake for 20–25 minutes, flipping halfway through; watch for golden edges and a little sizzle when you pull a pan close.
- Meanwhile, check for doneness: centers should be tender when pierced and rims should be deeply golden.
- Then, sprinkle the remaining Parmesan over the potatoes and return them to the oven for 3 more minutes, or until the cheese melts and becomes lightly golden and bubbling.
- Finally, remove from the oven and serve hot with your favorite dipping sauce — look for that crunchy edge and melty cheese on top.
Kitchen Tips (From My Kitchen)
- Time-saver: Slice potatoes while the oven heats so nothing waits.
- Common mistake + fix: If slices overlap, they steam; instead, use two pans or cook in batches.
- Variation: Add smoked paprika and chopped chives for a smoky, fresh twist.
Serving Ideas
- Weeknight dinner: pair with roast chicken and a simple green salad.
- Brunch side: serve with eggs and a dab of sour cream or aioli.
- Party nibble: pass them with a spicy ketchup or herb dip.
Also try them beside a creamy Tuscan chicken casserole for a full, cozy plate.
Storing & Leftovers
- Fridge: Keep in an airtight container for 3–4 days.
- Freezer: Not ideal; texture suffers, but you can freeze cooked rounds up to 1 month.
- Reheat: Warm on a sheet in a 400°F oven for 5–7 minutes to crisp back up.
Leftover idea: tuck slices into a sandwich with arugula and mayo for a quick lunch.

Notes
FAQs
Q: Can I make these ahead?
A: Yes — you can slice and season the potatoes an hour ahead, then bake when ready; keep them chilled meantime.
Q: What can I substitute for Parmesan?
A: Romano or Asiago work well, and for a dairy-free option try nutritional yeast. For more cheesy-bake ideas, I like the method used in this baked chicken with Parmesan recipe.
Q: How do I know when Oven Baked Potato Slices are done?
A: They’re done when centers pierce easily with a fork and the edges turn crisp and golden-brown.
Q: Can I freeze them?
A: You can freeze, but expect softer texture after thawing; re-crisp in a hot oven for best results. Also see this baked blooming onion for a party-side idea using similar reheating tips.
