Portobello and Cumin Spiced Eggplant Burgers

How does a person make up for a week of mac and cheese, popcorn for dinner and brownies?

With veggies of course. Lots and lots of veggies.

A year ago I saw this idea to use portobello mushrooms as a burger bun as a gluten free way to enjoy a good ol’ beef burger. So I decided to try it. I was amazed at how well it actually works. It was super juicy and surprisingly satisfying. I also recently saw a great idea in a Denis Cotter cookbook to use thick slices of eggplant as an interesting burger bun option. So I decide to mash those 2 ideas together. As it turns out it…it turned out pretty darn great.

I love this whole “thinking outside the box” thang. Mushrooms as bread? Crazy right?

Until you’ve tried it of course!

Everything goes in the oven at 450 F on one cookie sheet. 20 minutes later the burgers are quickly assembled and dinner is ready. Serve it with your favorite salad and voila, a healthy alternative to typical bbq night. And if you’re not an eggplant fan, no biggy. You can still use this concept with whatever filling you like.

Now I’m thinking about eggs benny with a portobello mushroom instead of that tired old English muffin. I’ve also seen these bad boys of the mushroom world used as the base for a pizza. Such a fab idea. Really there are so many possibilities. Fried egg sandwich, tuna melt sandwich…

Just so we’re clear, I’m talking about a grilled or cooked portobello mushroom. I don’t want you trying this with a raw mushroom. That wouldn’t be as tasty.

Try this idea with:

  • Roasted peppers and brie
  • Grilled zucchini, feta and olive tapenade
  • You’re favorite  burger pattie: veggie, fish, beef or lamb
  • Mashed Avocado, cilantro and sliced tomato
  • Gooey melted Buffalo Mozzarella, tomato and fresh basil

Note: In the photos I used 1 small eggplant. Use three mini slices of roasted eggplant per person. 1 small eggplant serves 2 people. Cut Eggplant spice recipe in half if only roasting 1 small eggplant.

Portobello and Cumin Spiced Eggplant Burgers

makes 4 burger

  • 8 Portobello mushroom caps
  • 1 large eggplant
  • Olive oil
  • Eggplant spice (see below)
  • Roasted Red Pepper Sauce or a very flavorful sauce of your choice like roasted tomato jam or chutney

Set the oven to 450 F. Using a paper towel, wipe clean the mushroom caps. Remove the stem. Brush the mushroom caps on both sides with olive oil and season the underside with salt and pepper. Set them on a baking sheet with tops facing down. Slice the eggplant into 3/4 inch to 1 inch slices. Brush the eggplant slices with olive oil and toss them with the spice mixture and place them on a cookie sheet. Bake the mushrooms and eggplant for 20 minutes, flipping the eggplant halfway through. To assemble, top 4 portobello mushroom caps with  1 to 2 slices of roasted eggplant, roasted red pepper jam and fresh cilantro. Cover with second mushroom cap and serve. Bring a big napkin. These are juicy.

Alternately, this can be done on the BBQ. The mushroom caps only take about 8 minutes per side when done on the grill. Eggplant will be approximately the same.

Eggplant Spice

for each large eggplant

  • 2 tsp ground cumin
  • 1/2 tsp smoked paprika
  • 1/2 tsp salt

Mix the 3 seasonings together and toss with eggplant before roasting.

Additional Topping suggestions:

  • Guacamole or Avocado Aioli
  • Salsa and cheddar
  • Grilled Haloumi and Mint Pesto
  • A whole roasted pepper (seeds and skin removed) and feta

    Ooh, this looks so yummy and unique indeed! I’m trying to imagine the sizing but portobello mushrooms can be quite large so I suspect I would not feel deprived 😉 particularly with all of your gorgeous accompaniment suggestions. Love the spicing too! Your photos are lovely in this segment France. Great light and clarity.

      I was surprised how satiated I felt afterwards. I think you’ll find it’s a Goldilocks situation, it’s JUST right. 😉

    This is an awesome idea! I’m a vegetarian and you’d think I would’ve thought if this on my own? Duh! I’ll probabably throw a slice of provolone on that or fresh mozzarella to melt just before putting it all together. Thanks

      That sounds like a wonderful idea. Let me know how you like it.

    It looks soooooo good. This is also my kind of food. I tried eating a hamburger on a roll, last night, and I took away the roll. The burger was well spiced and the roll just diluted the flavor. With mushrooms and eggplant, this wouldn’t happen.
