Ingredients You’ll Need
Here’s everything you’ll need to bring this dish to life. Each ingredient has a role in making sure you achieve the perfect flavor and texture:
- 2 pounds potatoes – Russet or Yukon Gold are best for crispness and fluffy interiors.
- 1 onion, halved and quartered – Adds sweetness and depth to the dish.
- ½ cup canola oil – High smoke point ensures crispiness.
- ½ cup olive oil – Adds flavor and richness.
- 4 cloves garlic, chopped – Brings savory, aromatic notes.
- 1 envelope onion soup mix – A shortcut to bold, savory seasoning.
- 1 tablespoon chopped fresh rosemary – Provides earthy, woodsy fragrance.
- 1 tablespoon freshly ground black pepper – Enhances all the flavors.
Step-by-Step Instructions
1. Preheat Your Oven
Set your oven to 450°F (230°C). A hot oven is crucial for getting those golden, crispy edges.
2. Prep the Potatoes and Onions
Wash the potatoes thoroughly and slice them into ½-inch-thick pieces. Thick enough to hold their shape but thin enough to crisp up beautifully. Cut the onion halves into quarters for chunky, caramelized bites.
3. Coat with Oils and Seasonings
Place the potatoes and onions in a roasting pan. Drizzle both canola oil and olive oil over them, then add chopped garlic, onion soup mix, rosemary, and black pepper. Toss until everything is evenly coated and glistening.
4. Cover and Roast
Cover the pan with aluminum foil and roast for 25 minutes. This allows the potatoes to steam slightly, softening their centers.
5. Crisp and Brown
Remove the foil and continue roasting for 15 to 30 minutes until the potatoes are browned and edges are crispy. Stir once or twice to ensure even cooking.
6. Serve and Enjoy
Remove from the oven and serve hot. Sprinkle with a little extra rosemary or sea salt if desired. These potatoes are best eaten immediately, straight from the pan while still sizzling.
Tips for Success
- Choose the right potato: Russet potatoes yield crisp edges, while Yukon Golds offer a creamy interior.
- Don’t overcrowd the pan: Spread potatoes in a single layer for even browning.
- Adjust seasoning: Add smoked paprika, cayenne, or thyme for a flavor twist.
- Flip halfway through: For maximum crispiness on both sides.
- For extra crunch: Broil for the last 2-3 minutes, watching carefully to avoid burning.
Variations to Try
This recipe is endlessly adaptable. Here are a few ways to put your own spin on it:
- Cheesy Potatoes: Sprinkle shredded cheddar or Parmesan during the last 5 minutes of roasting.
- Spicy Kick: Add red pepper flakes, chili powder, or Cajun seasoning.
- Herb Lover’s Version: Mix in thyme, parsley, or oregano alongside rosemary.
- Bacon & Potatoes: Toss in cooked, crumbled bacon before serving.
- Vegan-Friendly: Use all olive oil and skip cheese variations for a 100% plant-based dish.

Make-Ahead and Storage Tips
- Make-Ahead: Slice potatoes and onions a few hours early. Store them submerged in cold water to prevent browning. Drain and pat dry before roasting.
- Storage: Keep leftovers in an airtight container in the fridge for up to 3 days.
- Reheating: Re-crisp in a 400°F oven for 10 minutes. Avoid microwaving, as it softens the texture.
- Freezing: Best enjoyed fresh, but you can freeze roasted potatoes for up to a month. Reheat directly from frozen.
