Cut 1/4 inch slices across the width of each potato, ensuring you don't cut all the way through. (Tip: Put a wooden spoon behind your potato as you cut so you never cut all the way through, using it as a guide)
Place all the potatoes on a rimmed baking sheet.
While gently fanning out each potato, drizzle Olive Oil over all the potatoes, making sure to get in between the slices.
Sprinkle salt over all the potatoes.
Bake at 425 degrees for 50-60 minutes or until edges are crispy and center is cooked through.
Garlic Aioli
Mix mayonnaise, garlic, lemon juice, salt and pepper in a bowl. Cover and refrigerate for at least 30 minutes before serving.
Once the potatoes are cooked, arrange them in a casserole dish and drizzle Garlic Aioli on top. Finish with green onions or chives.
Notes
Tip for Garlic Aioli: If you are not liking the taste, alternate between adding more lemon juice or more salt. If you want a fresher taste, add more lemon juice.
