Ingredients
- 2 lbs (900g) potatoes, sliced (~½ inch thick)
- 1 large onion, cut into ¼-inch wedges (about 2 cups)
- ½ cup (120ml) canola oil (or vegetable oil)
- ½ cup (120ml) olive oil (adds richness and crispness)
- 4 cloves garlic, minced or chopped
- 1 packet (1 oz / 30g) dry onion soup mix (like Lipton)
- 1 tbsp dried rosemary (crush between fingers for best flavor)
- 1 tbsp freshly ground black pepper
- Salt (optional, depending on soup mix)
✅ Optional Add-Ins:
- Sprinkle of paprika or cayenne for heat
- Chopped fresh parsley or chives after baking
- Grated Parmesan cheese in the last 5 minutes
Step-by-Step Instructions
1. Preheat Oven & Prep Pan
- Preheat oven to 450°F (230°C).
- Line a large rimmed baking sheet with foil or parchment paper for easy cleanup.
2. Toss Everything Together
In a large bowl:
- Add sliced potatoes, onion wedges, canola oil, olive oil, chopped garlic, onion soup mix, rosemary, and black pepper.
- Toss well until every piece is evenly coated.
3. Spread & Roast Covered
- Pour mixture onto the prepared baking sheet.
- Spread into a single layer—don’t overcrowd.
- Cover tightly with aluminum foil.
- Bake 25 minutes, steaming the potatoes so they soften without burning.
4. Uncover & Crisp Up
- Remove foil carefully (watch for steam).
- Stir gently to flip some pieces.
- Return to oven uncovered and roast 15–30 minutes more, until:
- Potatoes are deeply golden and crispy on the edges
- Onions are tender and lightly caramelized
- A fork slides easily through the thickest potato slice
5. Serve Hot & Delicious
- Transfer to a serving platter.
- Optional: Sprinkle with fresh herbs or Parmesan cheese.
- Serve immediately while hot and crispy.
Pair with:
- Grilled chicken, steak, or pork chops
- Fried eggs for breakfast
- Or enjoy straight from the pan—they’re that good!
You Must Know
- Slice potatoes evenly —uniform cuts = even cooking.
- Don’t skip the double oil blend —canola helps crisp, olive adds flavor.
- Covering first prevents drying —creates steam for tenderness.
- Let them brown, don’t stir too much —crispiness needs space and time.
- Tastes better the next day? Reheat in oven or air fryer to restore crunch.
Storage Tips
- Store leftovers in an airtight container in the fridge for up to 4 days.
- Reheat in oven at 400°F for 10–12 minutes (best texture). Microwave works but softens crust.
- Freeze? Not recommended—the texture changes upon thawing.
