INGREDIENTS

Hash Browns

  • 1 medium russet potato
  • 1–1½ tbsp cornstarch
  • Neutral oil (canola or vegetable)
  • Garlic salt or regular salt

Meat

  • Italian sausage, about 6–7 oz total (enough for 2 patties)
  • 6 slices bacon

Sauce

  • Mayo: 1 cup
  • Sour cream: ½ cup
  • Worcestershire sauce: 1 tbsp
  • Lemon juice: about 2 tbsp
  • Hot honey: about 1 tbsp
  • Favorite hot sauce: about 2 tbsp

Fresh

  • Arugula or shredded lettuce

STEPS

Hash Browns

  • Peel the potato.
  • Shred it using the small holes on a box grater.
The smaller holes produce thin strips of shredded potatoes
  • Put the shredded potato in a bowl and cover with cold water.
  • Drain and refill with fresh water. Repeat 2–3 times until the water looks mostly clear.
  • Move the potato to a clean kitchen towel and squeeze as hard as you can until it is very dry.
  • Put the dry potato in a bowl and mix with the cornstarch only. Do not add salt yet.
  • Pour oil into a skillet so it is about ½ inch deep. The potato should be able to mostly sit in the oil.
  • Heat the oil over medium heat.
  • Do not pack the potato together. Gently sprinkle the loose potato into the oil in a circle to make a thin layer.
  • Fry until the edges turn light golden brown. Watch closely. Do not let it turn dark brown or it will taste bitter.
  • Carefully flip and cook the second side until light golden.
  • Take the hash brown out of the oil and immediately sprinkle with garlic salt or regular salt.
  • Place on a rack or paper towel. Do not stack.

Sausage

  • Divide the sausage into 2 small balls, each about the width of a quarter.
  • Heat a skillet over medium-high heat.
  • Place the sausage balls in the pan.
  • Lay parchment paper on top of each ball. Do not use wax paper.
  • Press down firmly with a burger smasher until the sausage is very thin.
  • Cook until the bottom is browned and cooked through.
  • Flip once, press again, and finish cooking.

Bacon

  • Cook the bacon until fully crisp with no soft spots.
  • Drain on paper towels.

Sauce

  • Put all sauce ingredients into a bowl.
  • Whisk until smooth.
  • Taste the sauce.
    • If it tastes too rich or creamy, add a little more lemon juice.
    • If it tastes bland, add more hot sauce or Worcestershire sauce.
    • If it tastes too sour or sharp, add a small spoon of mayo.
  • Mix again until smooth.

Build

For the best flavor, repeat this layering order so every bite tastes balanced: hash brown → sausage → bacon → sauce.

  • Hash brown
  • Sausage patty
  • Bacon (3 slices)
  • Arugula or shredded lettuce
  • Spoon of sauce
  • Bacon (3 slices)
  • Sausage patty
  • Hash brown

Press gently to set the sandwich. Do not smash it. Or smash it. Have fun with it!

TIPS

  • The hash brown should be thin and mostly sitting in the oil while frying.
  • Light golden color is perfect. Dark brown will taste bitter.
  • Always salt the hash brown after frying, not before.
  • Thin sausage patties cook better and make the sandwich easier to bite.
  • If the sandwich does not crunch on the first bite, focus on improving the hash browns.
