Taco-Stuffed Portobello Mushrooms – so many ways to enjoy!

Great entrée or appetizer – option for vegetarians included.

These low-carb taco-stuffed portobello mushrooms are really easy to make and deliver a ton of great flavor. Taco Tuesday may never be the same! Although we enjoy tacos with this mushroom stuffing too!

Flexible Uses for Taco Stuffing

This seasoned ground beef or ‘Beyond Beef‘ can be used in any way that you might also use round beef, including:

  • Stuffed Mushrooms –
    • large portobellos for dinner entree or side dish
    • small mushroom caps for finger food appetizers
  • Taco Shells
  • Burritos
  • Taco Salads
  • Chili – just add a little of your favorite broth. Use mushroom broth for the vegetarian version
  • Nacho toppings

If you have picky eaters who are determined to have their tacos, you can use this taco stuffing for taco shells as well. My son likes both, so we made extra so that he could load his tacos and also enjoy the variation with the portobello mushrooms.

Serving Ideas for Taco-Stuffed Portobello Mushrooms

How to Make Taco-Stuffed Portobello Mushrooms

To prepare the mushroom caps, gently remove stems by hand. Then, scoop out the gills with a spoon and discard. This will give you more room to add your toppings, plus it will remove the residual grit that can sometimes accumulate there.

Taco Seasoning

For the taco seasoning, you can use either your favorite prepared blend or make up a batch of this super easy homemade version that can be stored in an airtight container for up to six months.

This recipe uses fresh green onions, which we grow in our garden. However you can also top with chives or use your favorite onions instead. If you want to know more about the difference between chives vs green onions vs spring onions this should help.

You can also use garlic or onion chives from your yard or garden, especially plentiful in spring.

Alternate Ideas and Notes

  • Grill portobellos over grill or stovetop grill pan instead of in the oven.
  • Substitute a finely chopped or diced veggie mixture for the beef or substitute meat using whatever vegetables you have on hand.
  • Substitute the ground beef for grilled steak fajitas.
