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.
The mushrooms cook in about 10 minutes and dinner is ready!
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!

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!

Grilled portobello burgers is one of my favorite meatless treats. My family disagrees but that just means more for me! I love the pairing with blue cheese. I linked to this post in a round up of healthy father’s day recipes. http://www.halfhersize.com/healthy-fathers-day-recipes/ Thanks!
Thank you so much Rose! Hope you have a nice father’s day and thanks again!
Portobello Burgers and anything eggplant related are the two menu items I can’t get past…once I see them that is what I will order! This is a great meatless option.
I understand Cali – we love it too!~ This is a super tasty meatless meal I could eat again and again. Have a great week.
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!
You will love the mushroom burgers Susan! I am amazed at the flavor. It is juicy and satisfying. Thanks – grandsons are the best!

Thanks Abbe 🙂 Grilling season is coming soon! Thank goodness 🙂
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.
Thanks so much John. Have a lovely weekend!
