Grilled Portobello Caesar Salad – Low Carb and Gluten-Free

I don’t know about you, but I am seeing more and more creative recipes using mushrooms.  These little guys (or big guys, sometimes) are jam-packed with powerful nutrients, and they really are incredibly versatile. And, according to hieroglyphics, the ancient Egyptians believed that they were the plant of immortality.  Now, I am not sure if the ancient Egyptians ate them, bathed in them, or balanced them on their heads to derive these magical properties. But I’d far rather eat my mushrooms, thank you very much. I love mushrooms in almost any form: fresh, sautéed, grilled, pureed into soup. If you ask me to bathe in them or balance them on my head, well…then we might have a problem.

Grilled Portobello Mushrooms

Loving them as I do, I am delighted to be a part of the KitchenPlay Progressive Party with the Mushroom Council.  And thankfully, neither party asked me to bathe in them or balance them on my head.  They asked me to create a salad recipe for the Swap It or Top It promotion.  The idea being that mushrooms can be worked in to almost any recipe, and are a great way to swap out some or all of the meat to create a whole new dish.

Grilled Portobello Caesar Salad

That definitely gave me some food for thought.  I could easily create a salad featuring mushrooms, but I liked this “swapping it” idea and I wanted to play that up.  And these days, you don’t see too many plain Caesar salads; they are often topped with grilled chicken or fish.  So why not grilled mushrooms?  Big Portobello mushrooms are perfect for this, as they are thick and juicy and have a meaty quality to them.  They really took the Caesar to a whole new level.  I highly recommend making your own Caesar dressing.  What a taste difference!  But you can used bottled too, if you’d prefer.

    Love this twist on a caesar salad! My husband has a seriously weird affinity for them (like any time we go out, he orders one…it’s to the point of ridiculous) so I might have to throw this version at him for a curveball 😉 Really looking forward to meeting you August!

    Kind of right there with you on mushrooms – not sure I want to bathe in them but I sure do like to eat them. Portobello is my go-to mushroom for vegetarian options, love their earthy flavor and hearty texture. Great use with a Caesar salad.

    Bathing in mushrooms, not a pleasant thought. I do love them though. Grilled mushrooms are divine and paired with the ingredients of your salad, they look downright decadent.

    Only five comments? It’s because it’s salad. 😉 I think my salade niçoise recipe post got the lowest views ever (chuckle).

    This looks great. I bet you could make GF croutons too to have the complete effect. I love caesar salad dressing.

    PS I made your icebox cake and everyone loved it. I put it in a 9×13 pan because it was easier, and I puréed most of the strawberries and mixed them with the cream because I didn’t have enough in my garden. Big success!

      LOL, I was joking about this on my facebook page, saying if I’d added bacon, it would have garnered far more interest. It’s a really great salad, though. Nothing compares to homemade Caesar dressing (with anchovies!). And so very glad the cake worked out!

    My husband just discovered the large and chunky portobello mushroom the other day and will used them as burgers. It was insane delicious. Can’t wait to try this variation with them.

    I love the idea of a meaty grilled portobello mushroom on top of Caesar Salad! We must both have grilled Caesar Salad on the brain this week except I grilled the lettuce.
