Grilled Portobello Burgers with Blue Cheese and Onions – a terrific meatless Monday meal that’s inexpensive, quick, easy and will make the burger loving people in your family very happy!

Have you ever had a ‘meatless’ burger that tasted meaty and was really, really juicy? It’s almost shocking how much this tastes like a meaty burger and is so delicious. We topped our grilled portobello mushrooms with sautéed onions and wonderful rich blue cheese for a real treat.  Honestly these would be great with any kind of cheese or vegetables.  I’m going to try a few more ideas but even my husband asked if these could be on a regular rotation.  Absolutely – we really loved these healthy, meatless burgers!

It’s hard to beat a meal that starts with fresh vegetables and involves cooking over an open flame.  Less mess in the kitchen – woohoo!

The weather was absolutely perfect over the Easter weekend so it was a great time to dust off the old grill and fire it up!  The portobello mushrooms were cleaned then brushed with a mixture of balsamic vinegar, olive oil and garlic.  Marinate for 30 minutes while preparing the sautéed onions.

Throw in a cold beer and your burger-eating folks might think it’s still the weekend.  I added sliced ripe tomatoes and a little bed of lettuce then tried to get this giant burger in my mouth!  It took some effort but I managed!

 

 

Thanks for Pinning!

Recipe Notes

Recipe adapted from May/June 2012 Eating Well Magazine

We enjoy eating well and meatless Mondays are always delicious.  We love our Meatless Monday Taco Salad which is super hearty and delicious. This Spicy Pomodoro Sauce with Kale & Penne is filling and tasty dish that will leave you full and satisfied. We even made a crazy good meatless version of the Muffaletta – check out these Homemade Muffaletta Loaves & Vegetable Sandwich. Would love to try this Vegetarian Green Chile and Pinto Bean Layered Mexican Casserole from Kalyn’s Kitchen. And how about this Spinach Artichoke Pizza from Wine & Glue? It looks so delicious 🙂 And finally, how about this terrific lineup of 35 Weeknight Vegetarian Recipes to Embrace Meatless Monday from Bon Appetit!

Thanks so much for stopping by 🙂

    I have yet to try portobello burgers but your photos look so mouthwatering delicious that I don’t know what I’m waiting for! It’s wonderful to be able to grill again (and not freeze while doing so). These are going on my to-do list pronto! Your grandson is adorable, Tricia! I love that age 🙂 They are so full of excitement during the holidays!

    Whenever I’m doing something meatless but want a “meaty” flavor, I usually include portobello mushrooms. Isn’t their flavor magnificent! They’re better than meat. So I’m sure these burgers are terrific — they look to be loaded with flavor! Good stuff — thanks.

    I remember those days when our son was three….;) SOOO MUCH FUN!!! Your Portabella Mushroom Burgers look GREAT! The blue cheese sounds SOOO GOOD!!! 😉

    Tricia, I would love to find a recipe for home-made Fiber One Fiber Bars….. Any ideas? I recently found the Peanut Butter ones, & the store rarely has them now. 🙁 I guess everyone else loves them too.
