Copycat Bloomin Onion Appetizer Recipe (2024)

In a big bowl, combine mayonnaise, sour cream, ketchup, Worcestershire sauce, horseradish, paprika, Cayenne pepper, Kosher salt and black pepper. Cover bowl and place in refrigerator.

To slice the onion, cut off ½ inch from the pointy stem end of the onion, then peel.

Placing the onion cut-side down, start ½ inch from the root, and make a downward cut all the way through to the cutting board.

Repeat each step to make four evenly spaced cuts around the onion.

Continue slicing between each section to make 16 evenly spaced cuts.

Turn the onion over and using your fingers, gently separate the outer pieces.

Using another bowl, mix the flour, cayenne, paprika, thyme, oregano, cumin and ½ teaspoon black pepper, using a whisk.

Whisk the eggs, milk and 1 cup water in yet another small but deep bowl.

After placing the onion in a separate bowl with the cut-side up, pour all of the flour mixture on top.

Covering the bowl with a plate, shake back and forth to distribute the flour.

Make sure the onion is fully coated, especially between the flower petals from the cutting.

Lifting the onion by the core, turn over and pat off the excess flour.

Save this bowl of flour.

Fully submerge the onion in the egg mixture with a slotted spoon.

Remove onion, letting the excess egg drip off, and then repeat the flouring process.

Place onion in refrigerator while heating the oil.

In a large deep pot over medium-high heat, heat the oil until a deep-fry thermometer registers 400 degrees Fahrenheit.

Pat excess flour off of the onion.

Carefully lower the onion into the oil, cut-side down, using a wire skimmer.

Adjust the heat of the oil temperature so that it stays close to 350 degrees Fahrenheit.

Cook onion until golden, about 3 minutes on each side.

Drain on paper towels.

Salt to taste and serve with the dip.
