Taco-Stuffed Portobello Mushroom Caps

These delicious low-carb stuffed Portobello mushroom caps are really easy to make and deliver a ton of flavor. Taco Tuesday will never be the same!
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. For the taco seasoning, you can use either your favorite prepared blend or make up a batch of this super easy homemade version *recipe is below.

Prep time: 10 minutes
Cook time: 25-30 minutes
Serves: 4-6 servings

  • 3 T. extra virgin olive oil
  • 6 large Portobello mushroom caps, stems and gills removed

Directions for Stuffed Portobello Mushroom Caps:

  1. Preheat oven to 375° F and line a large, rimmed baking sheet with parchment paper or a Silpat® baking mat.
  2. With a pastry brush, brush olive oil on outside of each mushroom cap, and around the interior and edges. Set finished caps on lined baking sheet and set aside.
  3. Over medium-high heat, brown ground beef in a large skillet until no longer pink inside. Carefully drain off excess fat and return to heat.
  4. Add 2-3 T. taco seasoning mix and ½ cup water to skillet. Stir to distribute taco seasoning evenly. Cook on medium-high heat for 5-7 minutes or until excess water cooks down, stirring occasionally. Remove from heat and cool for a couple of minutes.

Bake for approximately 15 minutes, or until cheese is melted. Remove from heat and cool for a couple of minutes before serving.
