Do you get as excited about Taco Tuesdays (and Wednesdays and Thursdays and Fridays, you can see where we’re going with this) as us? Whether you need appetizers or a main dish, tacos are almost always a hit among family and friends, and can be a great vegetarian meal option.

These tacos use portobello mushrooms to make vegetarian tacos… hearty, easy, and absolutely delicious!

Why Use Portobello Mushrooms?

Portobello mushrooms belong to the cremini family which may seem strange if you do a size comparison. This is because smaller cremini mushrooms are harvested younger. Mushroom farmers allow their portobellos to grow more than four inches in diameter before they send them off for our mushroom taco dinners! (1)

If you’re searching for a healthy and less heavy option, these mushrooms are the way to go. One of these things is not like the other, but portobellos do measure up! (1) Many restaurants even use the “meaty” alternative in place of meat burgers on their menus.

Portobello Mushroom Nutrients


Portobellos’ size and unique texture aren’t its only attributes, they’re highly nutritious, too. We’ve highlighted its stacked nutrient list below: (1,2,3)

    • Macronutrients, e.g., carbs, protein, and low levels of fat
    • High in fiber which is beneficial for weight maintenance and helps control cholesterol and blood-sugar
    • They’re big in size but small in calories (i.e., a 100g serving is just under 30 calories)
    • Phosphorous which helps strengthen your bones and reduce muscle soreness
    • It’s B vitamins promote the formation of red blood cells, energy production, and nervous system function
    • Electrolyte mineral potassium aids muscle contractions, protein synthesis, nerve function, and acid-alkaline balance
    • The antioxidant compound selenium which is necessary for the thyroid and male reproductive system to function, and protects your cells (i.e., from heart disease, some cancers, and age-related diseases)
