Grilled Portobello Burger with Sweet Potato Fries

Who LOVES Mushrooms? 🙋 Me, me, me! I DO!

Someone once said to me, “I don’t think mushrooms taste like anything”… I think thats the most stunned I had been at the time. 😳. Mushrooms are EVERYTHING. Or to me they are. I feel like we grew up on mushrooms! Garlic mushrooms were a staple at every roast dinner. Give me a creamy mushroom pasta or mushroom pizza or anything really – I will probably add more mushrooms to it if thats on offer! I think you may all think I am officially crazy now but I could not love mushrooms more! So…

Enter the Marinated & Grilled Portobello Burger 😍

Seriously such a fun alternative to a beef burger on days you’re feeling like something just a little different! The mushrooms are marinated in a mix of balsamic vinegar, olive oil, lemon, dijon, garlic, maple syrup & thyme. I could pretty much put this marinade on a whole bunch of different things that’s for sure! Oh and the friesssss! Oh my goodness, sweet potato fries are just so great! It took me a while to get into the sweet potato fry trend…mainly because I love my sweet potatoes whole and served with a load of toppings 😍. However, I am ALL IN on cutting these beauties into matchsticks and baking them to seasoned crispy perfection! 

This is a pretty awesome vegetarian/vegan meal and also a perfect dish if you participate in the meatless monday challenge! We just LOVE that grilling season is truly here and we expect to be grilling up a lot more meats and veggies very very soon! So Stay tuned for some more awesome grilling goodness! 💚

  7. 1 tbsp. dried or fresh thyme

For the Sweet Potato Fries
  1. 3-4 sweet potatoes (dependent on size) - We LOVE them so 4 it is!
  2. 1/4 cup olive oil

Instructions
  1. Mix the marinade for your mushroom caps and set aside (vinegar, oil, juice, dijon, syrup (if using), garlic, thyme)

  3. Place all 4 into a large ziploc bag or dish ready to marinade

  5. Whilst your mushrooms are marinating make your sweet potato fries.
For the Sweet Potato Fries
  1. Preheat your oven to 400 F
  2. Peel and cut your sweet potato fries into equal lengths - about 1/2 an inch thick by 2 inches long.
  3. Toss with olive oil, thyme, salt & pepper until evenly coated
  4. Spread onto a parchment lined baking sheet - making sure not to overcrowd the sheet otherwise they will steam and not crisp!
  5. Bake at 400 F for 15 minutes, flip and cook for a further 15 minutes.
  6. Then turn the oven off and allow them to sit inside while you prepare the rest of your meal - 15-30 minutes.
To Grill the Burgers
  1. Remove the Mushroom caps from the marinade and heat your grill up on high.
  2. When grill is ready, grill your mushrooms (face down) for 3 minutes, flip and grill for a further 3 minutes.
