Portobello Mushroom Burger

A good veggie burger doesn't have to be boring, and this easy mushroom burger is a prime example. Toss those frozen, packaged veggie patties aside: all you need are portobello mushrooms to make an insanely flavorful vegetarian burger. A simple marinade brings all your favorite burger flavors to our meaty mushroom patty for a taste that doesn’t try to replicate your fave burger, but just might be your new preferred. Bonus: Roasting the portobellos means there’s no smoky grills to deal with for these burgers. It’s a win-win all around. 🙌 

Are portobello mushroom burgers vegetarian?
Technically yes, but one ingredient in our recipe isn’t 100% vegetarian: Worcestershire sauce. We love the smoky taste it gives these shrooms, but most contain anchovies, making them not fully vegetarian. If you’re looking to swap it out, look for a Worcestershire that doesn’t use anchovies, or simply swap it out for low-sodium soy sauce. 

Serving ideas.
We love ours simply topped with honey mustard, lettuce, and tomato, but like all burgers, you can really get creative with your toppings. Add on a melted slice of white cheddar, or your favorite vegan cheese! Swap out the honey mustard for your fave burger sauce, from ketchup to mayo to even the iconic Big Mac sauce. 

Looking for sides? Burgers beg to be served alongside homemade french fries, but don’t let your options stop there. Switch up the classic tater shape for air fryer potatoes or baked sweet potato chips. Or, add in some veggies with our classic pasta salad or Brussels sprouts chips.
