Baked Blooming Onion

Unless you’re an onion-hater, you’ve probably given in to the deep-fried sensation of the blooming onion prepared by that famous steakhouse. That creation, which, depending on what website you read, clocks in at between 2,000 and 3,000 calories and a whopping 134 grams of fat. That’s even before you dip those fried petals into the mayonnaise-based dipping sauce.

Here’s a recipe for a healthier, Baked Blooming Onion. Is it as good as the deep fried one? Not quite, but it does come close.

This recipe cuts calories to below 1,000 and fat to around 50 grams, based on the whole onion, not just one serving. This is my best guess from information I found on several sites.

The Cutco Trimmer, with its Double-D® edge, makes preparing the onion quick and easy. The tip of the blade easily inserts into the onion and the sharp blade moves smoothly when cutting the grid pattern into it.

Preparing the onion with a trimmer.

Refer to our infographic on How to Make a Blooming Onion for step-by-step instructions on how to do it, in just five easy steps.

Once it’s done, the onion is ready to dip into an egg mixture.

Dip the onion in the egg mixture.

And then it goes into breadcrumb mixture, but as noted in the recipe, be sure to coat the petals fully.

coating the onion with breadcrumbs.

For the dipping sauce, feel free to use light mayo and sour cream to further trim the calorie count.

Consider using the dipping sauce on its own for a crudité platter filled with things like carrots, celery, bell peppers, cauliflower, or whatever vegetable you like!
