It is literally impossible for me to make this or any kind of burger recipe without quoting the scene from the reboot of the Pink Panther, where inspector Jacques Clouseau (played by Steve Martin) is trying to learn to speak with a more Americanized accent. I’m sure Lauren (and most likely our neighbors) must find it annoying. However it is a very satisfying phrase to half yell in your best/worst French accent, go ahead try it…see wasn’t that fun?
This is one of those recipes I make all the time for myself. It reminds me of a more nutritious version of the countless hamburger helper meals I made until I learned how to cook. If it hadn’t been for hamburger helper and my George Foreman grilled chicken breasts my diet would’ve limited to take-out, scrambled eggs, and chex mix. Thankfully I am much more confident in the kitchen nowadays and these Keto Cheeseburger Stuffed Portobello Mushroom Caps are simple, delicious, and hit the spot every time.

Keto Cheeseburger Stuffed Portobello Mushroom Caps
Ingredients
- 6 portobello caps
- 1 tablespoon oil of choice
- 1 lb ground beef
- 2 cups shredded cheddar
- 4 slices bacon
- 1 teaspoon garlic salt
- ¼ cup minced onion
- ¼ cup diced pickles
- ¼ cup diced tomato
Top:
- ½ cup shredded lettuce
- mustard
Instructions
- Preheat oven to 450° F.
- Remove the middle of the mushroom caps and use for another recipe. Toss the caps with the olive oil, set aside.
- Heat a 10.5” cast iron skillet over medium high heat. Add the bacon to the skillet and cook until crispy. Remove, chop, and set aside leaving the grease in the skillet.
- Add the ground beef to the skillet and cook until browned, about 7 minutes. Add the chopped bacon back to the skillet and mix to combine. Transfer the beef mixture to a bowl along with the shredded cheddar, garlic salt, onion, pickles, and tomato.
- Divide the mixture between the portobello caps, place the caps in the skillet and transfer to the oven for about 10 minutes until the cheese is melted.
- Top with the lettuce and mustard before serving.
I plan to make these for dinner. I hope they are half as good as the laugh I had watching Steve Martin saying he would like to buy a hamburger. I have not stopped saying this since I watched it. Thanks for the recipe. I look forward to trying it.
