Portabella Mushrooms - No Bun, No Extra Cheese

Rose Mary Mogan


I recreated this recipe from one I already have posted but used less cheese, less bacon, and no bun so that it came well within the guideline of my low carb eating. In calculating the recipe for nutrition using My Fitness Pal, it has a substantial amount fewer calories than the first one I posted awhile back.

They are both delicious and you really do not miss the extra strip of bacon, or extra cheese or the bun. My husband ate three & I had one. The calories came in at 243 per serving and were very satisfying. The best part is it is simple and easy to make. This recipe makes 7 servings.

Portabella mushrooms are meaty and filling. This dish is so full of flavor you forget there isn't a bun. All the flavors from this "burger" come through from the fresh ingredients and not fancy seasonings. Building this bunless portabella burger can be as big or as little as you want. In the Test Kitchen, we followed Rose Mary's recommendation and it was delish. We loved the peppers stuffed inside along with the cheese. The bacon wrap not only added flavor but texture after it crisps perfectly in the oven. Served on a bed of lettuce with a pickle and tomato, it's a delicious low carb meal.

How to Make Portabella Mushrooms - No Bun, No Extra Cheese


  1. Pre-heat oven to 375 F.
  2. Clean the mushrooms with a paper towel, then remove the stems. Clean the underside with a medium size spoon, removing the brown scale-like texture, which is referred to as the gills.
  3. Brush both the top and underside of mushroom with olive oil if desired.
  4. You will need a shallow pan like a jelly roll type. Spray with non-stick cooking spray and add each of the mushrooms. Set aside until needed.
  5. Chop the stems along with the red bell pepper, mini sweet peppers and garlic, or use a food processor.
  6. Add the olive oil to a large skillet. Then add the peppers with mushroom stems and saute until tender and transparent. Remove from heat and set aside.
  7. Now slice the onions. Top each mushroom cap with a slice of sharp cheddar cheese. Then add two onion slices on top of each cheese slice.
  8. Divide the sauteed pepper mixture evenly atop each of the mushrooms.
  9. Next, when cool enough to handle, wrap each mushroom portion with 2 slices of the smoked bacon strips, over the top in a crisscross pattern and tucking underneath. Repeat until all are wrapped.
  10. Now place the pan in preheated 375 degree oven and bake for 25 minutes.
  11. Then, increase the temperature to 400 degrees and continue baking for an additional 20 minutes or until bacon is cooked crisp and golden brown, or as desired.
  12. Serve without bun for low carb eating, or with a bun, as desired, with the suggested condiments. Enjoy.
