These crispy smashed potatoes are served over a generous layer of homemade French onion dip, then finished with truffle oil, fresh dill and crunchy fried onions. Crispy, creamy and packed with savory onion flavor!
Add a drizzle of olive oil to a medium sized skillet then transfer onions to pan and cook over low heat for 35-45 minutes, stirring occasionally until onions are soft, dark and caramelized
Add salt, pepper, garlic and thyme. Stir and allow to cook an additional minute
Deglaze the pan with white wine, scraping the brown bits from the bottom. Add sherry vinegar and beef broth then allow to reduce until almost all liquid is gone
Transfer onion mixture to a heat proof bowl then allow to chill in the fridge or freezer for 10-15 minutes. After chilling, mix in sour cream, mayo and additional salt then set aside until needed
Potatoes
Add potatoes to a pot of cold water. Add enough kosher salt to make the water taste like ocean water, this will help season the potatoes from the inside out. Bring pot to a boil for about 10 minutes. Test potatoes by inserting a paring knife to see if it goes in with little to no resistance and slides back out
Drain potatoes well then transfer them to a sheet tray. Use the bottom of a cup or mug to smash them. Smash them just enough that they flatten but don't start to break apart. Lightly dust with salt and pepper
Bring approximately ¼ inch of oil to 350°F then add potatoes, keeping them spaced out and not over crowding the pan. Allow them to cook undisturbed for 2-3 minutes per side then transfer them to a paper towel lined sheet tray to absorb any extra oil and sprinkle with additional salt and pepper
Smear onion spread over a serving platter, top with fried smashed potatoes, then top with fried onions, dill, chives and a drizzle of truffle oil
Notes
Don't forget to salt the water you boil the potatoes in. It should taste like salty ocean water. This helps season the potatoes from the inside out.It's important not to overcook the potatoes. If they're too soft they will fall apart when you smash them.Use a neutral olive oil, peanut oil or avocado oil. These oils all have a high enough smoke point that they won't burn when pan frying. If using olive oil, be sure you don't reach for extra virgin olive oil as it has a lower smoke point and will burn when pan frying. It also has a much stronger taste.A very light drizzle of truffle oil will go a long way. It's pungent flavor can be overpowering.
