Onion Petals with Horseradish Sauce

I think many of us are now familiar with blooming onions, onion petals, and those amazingly tangy horseradish sauces. This is our take on the best of all worlds. We personally found blooming onions difficult to make at home, with under-cooked portioned of onion at the base, or a large mess – for that reason, we switched to onion petals. We also tweaked the seasoning of the sauce to suit our preferences and hope that you’ll enjoy as well!

Equipment

• Deep fryer

Ingredients

  

Horseradish Dipping Sauce

• ½ cup mayonnaise
• 2 Tbsp ketchup
• 1 Tbsp prepared horseradish e.g. Boar's Head Horseradish grated in vinegar
• 1 tsp black pepper
• ½ tsp salt
• ½ tsp garlic powder
• ¼ tsp cumin
• ¼ tsp oregano

Onion Petals

• 1-2 small yellow onions
• 1 egg
• 1 cup milk
• 2 cup flour
• 1 Tbsp smoked paprika
• 1 Tbsp oregano
• 1 Tbsp cumin
• 2 tsp salt
• 1 tsp cayenne pepper
• 1 tsp black pepper
• 1 tsp garlic powder

Instructions

 

Horseradish Dipping Sauce

• In a small bowl or jar, mix all ingredients until well combined. Cover and refrigerate at least 1 hour before serving.

Onion Petals

• Heat peanut oil (or other preferred frying oil) in a deep fryer or dutch oven until 350°.
• Slice the ends off of your onions, then cut them in half. Slice the onions into 1 inch petals and set aside.
• Mix your egg and milk in a small bowl. Mix all remaining dry ingredients in a separate bowl.
• Dip onions into the wet batter, then into the dry, back into the wet, and then into the dry again.* (see note) Set aside and repeat until all onion petals are battered.
• Gently place onion petals into hot fry oil, taking care to avoid them all clumping together. Fry until medium brown, 3-5 minutes. Place on paper towel or wire rack to strain in between batches.

Notes

• * Note on dipping – it is possible to skip the second dip in the wet and dry batters, however we have found that the coating sticks better to the onion petals with a second dipping. Still delicious even with one.
