Who doesn’t love Taco Tuesday? Tacos are always crowd pleasers and taco bars are a convenient way to serve a large group of people. We’ll never turn down a good meat and cheese taco, but adding these hearty and flavorful Corn and Mushroom Tacos with Avocado Crema to our taco bar is a delicious way to add some veggies to the spread as well as please any non-meat eating guests.

A Mushroom Taco Recipe full of traditional taco flavors

You’ll find all the flavors of a regularly seasoned taco here – cumin, oregano, chili powder, garlic and onion – with a few surprises. A mild heat comes from the poblano pepper and bit of hot sauce, while the fresh lime juice and cilantro keep the taste bright.

How to make Avocado Crema

I like to top these Corn and Mushroom Tacos with a dollop of cooling avocado crema, which is just a fancy way of whipping together some avocado, sour cream and lime juice, but feel free to keep your avocado and/or sour cream separate and garnish with whatever makes you happy.

Tip: Is your avocado crema too thick? Add a bit more lime juice to loosen the consistency.


Meatless Tacos for Meat Lovers

Try these Corn and Mushroom Tacos with Avocado Crema at your next Taco Tuesday. You’ll be surprised at how tasty they are, plus they are similar enough in flavor to classic tacos – sans meat – to give even “taco purists” reason to branch out and try something new.


Suggestions for equipment to make these Corn and Mushroom Tacos with Avocado Crema:

  • I love using this tortilla warmer when we have a big taco buffet. It helps keep the tortillas warm and pliable whether you are the first or last guest through the buffet line.
  • This is one of the few cutting boards I’ve used that doesn’t immediately dull my knives. Plus I love the back story of how they are made from recycled materials.
