Perfect for:

• Weeknight dinners
• Holiday meals (Thanksgiving, Easter, Christmas)
• Meal prep (reheats beautifully)
• Feeding a crowd

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.

Ingredient Substitutions

Serving Suggestions

• Serve family-style on a platter with dipping sauces.
• Great for potlucks—bring the whole pan!
• Double the batch and freeze half for future comfort.
• Pack in lunchboxes (reheat safely).
