Step-by-Step Instructions
Follow these steps to ensure perfectly cooked potatoes every single time.
1. Prep the Potatoes
Start by washing about 2 pounds of red potatoes thoroughly. Pat them dry with a kitchen towel—excess moisture is the enemy of a crisp potato. Cut the potatoes into uniform wedges or quarters (about 1.5 inches thick). Keeping the sizes consistent ensures they all finish cooking at the same time.
2. The Coating Process
In a large mixing bowl, toss the potato wedges with 1/3 cup of olive oil. Once the potatoes are glistening, sprinkle one full packet (approx. 1 oz) of dry onion soup mix over them. Use a large spoon or your hands to toss everything together until the seasoning is evenly distributed.
3. Arrange for Success
Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or aluminum foil for easy cleanup. Spread the potatoes out in a single layer. If the pan is crowded, the potatoes will steam instead of roast. Make sure there is a little bit of “breathing room” between the pieces.
4. Roast to Perfection
Place the baking sheet on the middle rack of the oven. Roast for 35 to 45 minutes. Halfway through the cooking time, use a spatula to flip the potatoes. This ensures that the side touching the pan gets that signature dark, caramelized crust without burning.
5. The Finishing Touch
The potatoes are done when they are fork-tender and the edges are golden brown and slightly crispy. Remove them from the oven and let them rest on the pan for 2–3 minutes before serving. This allows the juices to settle and the coating to firm up.
Pro Tips for the Best Results
-
Dry them well: If the potatoes are even slightly wet after washing, the oil won’t stick properly, and the seasoning will become clumped rather than a smooth glaze.
-
High Heat is Key: Don’t be tempted to lower the temperature. The 400°F environment is what triggers the Maillard reaction, turning the onion bits in the soup mix into those delicious, savory morsels.
-
Add a Fresh Element: While the recipe only requires three ingredients, a sprinkle of fresh parsley or a squeeze of lemon juice right before serving can add a bright contrast to the deep, savory flavors.
Storage and Reheating
If you happen to have leftovers, these potatoes store beautifully in an airtight container in the refrigerator for up to four days.
To maintain the texture, avoid the microwave when reheating. Instead, pop them back into a toaster oven or air fryer at 350°F for about 5 minutes. This will revive the crispy exterior while keeping the inside fluffy.
Frequently Asked Questions
Can I use other types of potatoes? Yes! Yukon Golds are a great alternative as they are also buttery and waxy. Avoid Russet potatoes if possible, as their high starch content makes them better for mashing or frying rather than this specific roasting style.
Is this recipe gluten-free? It depends on the brand of onion soup mix you use. Many standard mixes contain barley or wheat-based thickeners. If you are cooking for someone with a gluten sensitivity, be sure to check the label for a certified gluten-free brand.
Can I make this in an Air Fryer? Absolutely. Follow the same prepping steps and air fry at 380°F for 18–22 minutes, shaking the basket halfway through.
