Onion Garlic Butter Fries (Printable)

Crispy fries coated in caramelized onion and garlic butter for a flavorful side dish.

# What You'll Need:

→ Potatoes

01 - 4 large russet potatoes, scrubbed and cut into thick fries
02 - 2 tablespoons olive oil
03 - 1 teaspoon kosher salt
04 - ½ teaspoon black pepper
05 - ½ teaspoon smoked paprika

→ Onion-Garlic Butter

06 - 4 tablespoons unsalted butter
07 - 1 large yellow onion, thinly sliced
08 - 3 cloves garlic, minced
09 - 1 tablespoon fresh parsley, chopped
10 - ½ teaspoon sea salt
11 - ¼ teaspoon black pepper

# How to Make It:

01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, toss potato fries with olive oil, salt, pepper, and smoked paprika until evenly coated.
03 - Arrange fries in a single layer on the prepared baking sheet. Bake for 35-40 minutes, flipping halfway through, until golden brown and crisp.
04 - While fries are baking, melt butter in a large skillet over medium heat. Add sliced onions with a pinch of salt and cook, stirring often, until caramelized and deeply golden, about 15-18 minutes.
05 - Add minced garlic to the onions and cook for 1-2 minutes until fragrant. Stir in chopped parsley and remove from heat.
06 - Transfer hot fries to a large bowl. Pour the onion-garlic butter mixture over the fries and gently toss to coat.
07 - Garnish with extra parsley and serve immediately.

# Expert Tips:

01 -
  • The crispy exterior and pillowy inside happen without any deep-frying hassle, just honest oven work.
  • Caramelized onions and garlic butter elevate simple potatoes into something that feels fancy but tastes like comfort.
  • You can have everything ready in under an hour, making it the perfect weeknight side that actually impresses.
02 -
  • Soaking cut potatoes in cold water for 30 minutes before roasting removes excess starch and makes them noticeably crispier—this one change was a game-changer the first time I tried it.
  • Don't rush the onions; low and slow caramelization is what transforms them into something complex and sweet, not just softened slices.
03 -
  • Arrange fries in a single layer without crowding—overcrowding the baking sheet traps steam and ruins that crispy exterior you're after.
  • Keep your skillet at medium heat while caramelizing onions; high heat burns them before they have time to develop that deep, complex sweetness.
