Baked Blooming Onion

When I think blooming onion, I think CALORIES. Thousands of calories.  But it’s SO good. So I came up with a recipe that’s a fraction of the calories, and it’s delicious. My Baked Blooming Onion is sweet and spicy, without the oily aftertaste. With just a few ingredients you can make this recipe for a side dish or for a snack.


Take the outer paper off an onion. Cut the top off, but leave the bottom on.  Cut into wedges without cutting the bottom so it stays intact. Gently open up the onion wedges. Sprinkle with spices and then spray the onion with cooking spray. Bake at 400 for 20 minutes. In the meantime, mix mayo and ketchup with the same spices for a dipping sauce.
