  • 1 large sweet onion
  • cumin
  • paprika
  • cayenne pepper
  • dried thyme
  • black pepper
  • sea salt
  • 1/2 C. paleo mayo
  • 2 Tbsp. tomato paste
  • 1.5 tsp. horseradish
  • 1/2 seasoning salt I like 21 Salute by Trader Joe's
  • pinch of red pepper flakes


  • Preheat oven to 400*
  • Place onion on foil lined baking sheet
  • Slice pointy, non-root end of onion off. Just about 1/2 an inch
  • Peel skin off of onion
  • Flip onion and place cut side onto cutting board
  • Starting at top and leaving roughly 1/2 inch at top slice onion down to bottom. Do this 4 times around so that you have four even segments
  • Using that technique, continue to do so until you have 16 even sections around the onion
  • Flip and gently pull onion "petals" down, separating the segments
  • Drizzle or spray olive oil onto onion lightly coating each petal
  • Lightly sprinkle cumin, paprika, cayenne pepper, dried thyme and pepper over top of onion making sure to spread petals apart in order to evenly coat
  • Repeat with salt but feel free to be a bit more liberal with the salt than other seasonings
  • Place in oven and bake for 20 minutes or until onion is soft and edges are crispy
  • Meanwhile add tomato paste, horseradish, seasoning salt, red pepper flakes to paleo mayo and combine. I prefer to use my immersion blender to do so
  • Once onion is done, transfer to plate and serve w dipping sauce
