How to Make Crispy Oven-Fried Potatoes & Onions

Step 1: Warm Up the Oven

Fire up your oven to a blazing 450F (230C). This high temperature will help create those irresistible golden-brown edges on your potatoes.

Step 2: Prepare Flavor Explosion

Grab a large roasting pan and toss in these delicious ingredients:
  • Chunky potato pieces
  • Sliced onions
  • Canola oil
  • Olive oil
  • Minced garlic
  • Onion soup mix
  • Dried rosemary
  • Freshly ground black pepper

Stir everything together until each potato and onion piece is generously coated with the aromatic oil mixture.

Step 3: Initial Roasting

Cover the roasting pan tightly with aluminum foil.

Slide the pan into the preheated oven and let the potatoes steam and soften for about 25 minutes.

Step 4: Create Crispy Perfection

Remove the foil and return the pan to the oven.

Continue roasting for another 15-30 minutes. Watch as the edges turn deliciously golden and crisp, with onions caramelizing to sweet, deep brown edges.

Step 5: Serve and Enjoy

Transfer your crunchy potato medley to a serving dish. These make an incredible side that pairs perfectly with roasted meats, grilled chicken, or as a standalone snack.

Pro Tips for Perfect Oven-Fried Potatoes & Onions

  • Opt for waxy potatoes like Yukon Gold for the best texture and even browning during roasting.
  • Slice onions and potatoes uniformly to ensure consistent cooking and crispy edges.
  • Pat potatoes dry before mixing with oil to help achieve maximum crispiness and prevent sogginess.
  • Stir the mixture halfway through roasting to promote even browning and prevent sticking to the pan.
  • Experiment with different herbs like thyme or oregano to add variety and enhance the flavor profile of the dish.

Variations to Enhance Oven-Fried Potatoes & Onions

  • Herb Garden Blend: Swap rosemary with fresh thyme, oregano, or mixed Italian herbs for a vibrant herbal flavor profile.
  • Spicy Kick Variation: Add paprika, cayenne pepper, or red pepper flakes to introduce a warming, zesty heat to the potatoes and onions.
  • Low-Carb Alternative: Replace regular potatoes with cauliflower florets or turnips to create a lower-carbohydrate version of the dish.
  • Vegan Friendly Option: Use avocado oil instead of canola and olive oils, and ensure the onion soup mix is plant-based for a completely vegan preparation.

Pairing Suggestions for Oven-Fried Potatoes & Onions

  • Savor Complementary Flavor Combinations: Hearty red wines like Cabernet Sauvignon brilliantly cut through the potatoes' richness with their bold tannins.
  • Pair with Protein Partners: Grilled lamb chops or roasted chicken create a delectable match, balancing the crispy potato's texture with tender meat.
  • Herbaceous Herb Enhancement: Fresh chopped parsley or chives sprinkled on top will elevate the dish's earthy rosemary undertones, adding bright, zesty notes.
  • Mediterranean-Inspired Dipping Sauce: Prepare a quick tzatziki or garlic aioli for an extra layer of creamy, tangy enjoyment that complements the potatoes' crisp exterior.

Storing Oven-Fried Potatoes & Onions Properly

Store leftovers in an airtight container within 2 hours of cooking. Keep refrigerated for up to 3-4 days, maintaining best quality and food safety.

Transfer cooled potatoes to freezer-safe containers or zip-lock bags. Freeze for maximum 2 months. Seal tightly to prevent freezer burn and preserve flavor.

Spread potatoes on a baking sheet, cover with foil to prevent drying. Warm at 350F for 10-15 minutes, removing foil for last 5 minutes to restore crispiness.

Quickly revive potatoes in a hot skillet with a drizzle of olive oil. Sauté for 5-7 minutes, stirring occasionally to ensure even heating and crisp texture.

FAQs

  • Can I use other types of potatoes for this recipe?

Yes, you can use Yukon gold, red potatoes, or russet potatoes. Just ensure they are cut into similar-sized pieces for even cooking.

  • Is onion soup mix necessary for the recipe?

The onion soup mix adds depth of flavor, but you can substitute with dried herbs like thyme or a blend of garlic powder and dried herbs if needed.

  • How do I ensure my potatoes get crispy in the oven?

The key is removing the foil midway through cooking and using a combination of oils. Also, make sure potatoes are not overcrowded in the pan to allow proper browning.

Ingredients

Scale

Oils and Flavor Enhancers:

  • 1/2 cup canola oil
  • 1/2 cup olive oil
  • 1 envelope onion soup mix
  • 1 tablespoon fresh rosemary
  • 1 tablespoon black pepper

Instructions

  1. Prepare the baking surface by lightly greasing a roasting pan to prevent sticking and ensure easy cleanup.

  3. Thoroughly coat the potato and onion mixture with oils, garlic, soup mix, rosemary, and black pepper, ensuring each piece is evenly seasoned for maximum flavor penetration.

  5. Uncover the pan and continue roasting, allowing the potatoes and onions to develop golden-brown crispy edges and caramelized surfaces.
  6. Monitor the vegetables closely during the final 15-20 minutes to prevent burning while achieving a perfect crisp exterior.

Notes
