First mix the ranch and mayo in a medium-sized bowl until completely blended, then set aside.
Shred 8-ounces cheddar cheese then add it to the ranch and mayo mixture.
Stir to combine with the dressing, then rest in the fridge until needed.
Cook the potatoes
Rinse the potatoes in a sink colander.
On a cutting board, dice the potatoes into inch cube pieces.
Once the potatoes are cut, add them to a steamer basket in a large pot and then steam until a fork is inserted easily, between 5-10 minutes. You can also choose to boil the potatoes.
When the potatoes are fully cooked, remove them from the steamer basket with a large spoon to a large bowl.
Then, rest the potatoes to cool to room temperature before cooling in the fridge.
When the potatoes are cooled, combine them in a large bowl with the shredded cheese and dressing mix.
Cook the onion and bacon
Stack up the 6 pieces of bacon on a cutting board and then cut it into small pieces; around 1-2 inches.
Cook the bacon pieces for 10 minutes in a pan on the stove.
On a cutting board, cut an onion in half and then peel the skin off. Then, dice the onion and add to the cooking bacon.
When the bacon and onion are fully cooked, transfer it onto a paper towel lined plate to cool.
Cook the Broccoli
Wash broccoli in a sink colander, then on a cutting board, cut the base of the broccoli off and slice the head into smaller chunks.
Cook the broccoli in a steamer basket for 7-10 minutes, or until tender.
When done, put them in a dish and dash a bit of salt on them for flavor. Then set aside to cool.
Mix the Steakhouse Potato Salad
When the bacon is fully cooled, transfer them from the plate into the bowl and mix it into the potatoes, then stir carefully to combine with a large spatula.
Add salt and pepper to taste and then add dried parsley if using.
Hard-boil the eggs
Bring 2 cups water to a boil in a small saucepan and then boil 3 eggs for 5-7 minutes.
Once done, remove the eggs and transfer to an ice bath to stop the cooking.
Peel the eggs and then slice them, finally adding them to the Steakhouse potato salad.
Notes
Cooling in the fridge while still hot can alter the contents of your fridge and can put foods at risk from varying temperatures. Make sure that anything you put into a fridge after being cooked is fully cool to room temperature.
