Ingredients
- 2 pounds potatoes, sliced into ½-inch rounds
- 1 large onion, halved and quartered
- 4 cloves garlic, chopped
- 1 tablespoon fresh rosemary, chopped
- ½ cup canola oil
- ½ cup olive oil
- 1 packet onion soup mix
- 1 tablespoon freshly ground black pepper
Step-by-Step Instructions
- Preheat your oven: Set the oven to 450°F (230°C) and allow it to reach temperature before placing your potatoes and onions inside.
- Prepare the potatoes and onions: Slice the potatoes into thick ½-inch rounds to ensure they roast evenly and hold their shape. Cut the onion into large, chunky sections by halving and quartering for a robust texture after cooking.
- Arrange in a roasting pan: Place the potatoes and onions into a large roasting pan or a baking sheet lined with parchment paper to prevent sticking and facilitate cleanup.
- Add oils and seasonings: Pour the canola oil and olive oil evenly over the potatoes and onions. Then add the chopped garlic, sprinkle the onion soup mix, freshly chopped rosemary, and black pepper on top.
- Mix to coat: Use a large spoon or your hands to thoroughly toss everything together until each piece is evenly coated with oil and seasonings.
- Cover and roast: Tightly cover the pan with foil to help steam the potatoes and onions, creating softness inside. Roast in the preheated oven for 25 minutes.
- Uncover and continue roasting: Remove the foil carefully, stir the mixture once to promote even browning, then continue roasting uncovered for an additional 15 to 30 minutes until the potatoes are golden brown and crispy, and the onions have caramelized beautifully.
- Serve warm: Once done, remove from the oven and serve immediately to enjoy the perfect mix of crispy texture and rich flavor.
Pro Tips for Perfect Oven-Fried Potatoes and Onions
- Choose the right potatoes: Use starchy or all-purpose varieties such as Russets or Yukon Golds for the best crispiness inside and out.
- Slice uniformly: Cutting the potatoes evenly ensures they cook at the same rate and achieve consistent texture.
- Don’t skip coating: Thoroughly mixing the potatoes and onions with oils and seasonings will guarantee every bite bursts with flavor.
- Stir once mid-way: Stirring during roasting helps each side brown evenly and prevents sticking or burning.
- Use foil to steam first: Covering the pan initially traps steam, making the potatoes soft inside before crisping the exterior once uncovered.
Variations and Substitutions
Looking to switch things up or make this recipe even healthier? Here are some great options:
- Healthier oil swap: Replace canola and olive oil with avocado oil or use half the amount for fewer calories without compromising flavor.
- Herb alternatives: If fresh rosemary isn’t on hand, try thyme, oregano, or a dried Italian herb blend.
- Additional veggies: Add sliced bell peppers, cherry tomatoes, or zucchini for color and extra nutrients.
- Low sodium: Use a low-sodium or homemade onion soup mix to control salt intake while retaining flavor.
- Make it spicy: Add a pinch of cayenne pepper or chili flakes in the seasoning mix for a subtle kick.
Storage and Reheating Tips
To store leftovers, place cooled oven-fried potatoes and onions in an airtight container and refrigerate for up to 3 days. To reheat, spread them on a baking sheet and warm in a 375°F (190°C) oven for about 10-15 minutes until hot and crispy again. Avoid microwaving as it may make them soggy.
