I love simple meals that don't take long to prepare and this recipe is definitely one of them. If you want to add more protein, eat with some crisped up bacon or high-quality ham. If you want to add some heart-healthy fats, eat with avocados.
Here are a few reasons why you should eat mushrooms:
- they are low in net carbs and calories (2-4 g net carbs per 100 g/ 3.5 oz)
- they are a good source of fiber
- they are a great source of potassium which helps with "keto-flu" when you are on a low-carb diet (this recipe gives you about 35% RDA of potassium per portion)
Step-by-step
Preheat the oven to 175 °C/ 350 °F (fan assisted), or 195 °C/ 380 °F (conventional). Clean the mushrooms and remove the stem. Season with salt to taste.

Chop the stems into small pieces and add fresh thyme leaves.

Fill each mushroom with crumbled blue cheese, chopped stems and thyme. Place in the oven for about 20 minutes.

Remove from the oven and place on a serving plate with fresh greens tossed with olive oil. Serve immediately or store the mushrooms in the fridge for up to 3 days and reheat before serving.

I wish you'd put a small photo in the print part of your recipes. I often end up tossing recipes after printing if I don't have a photo. They're just not as alluring. That's why I love AllRecipes.com, except there aren't many keto recipes, and NO Fat Bombs, of course.
You could also add branding at the top, after the recipe's name, such as:

Best wishes! (I just found your blog so can't comment on it or the recipes.)
Thank you Jeffrie, there is a photo on the top right - could it be your browser/printer? 😊
I had some portobellos that I needed to use (you know how use-or-lose is) today, and this looks perfect. Thank you so much!
I hope you like it! 😊
It looks pretty simple but yummy! I think i'll try it with feta cheese as i don't have any blue. Did the mushrooms get soggy though?
Thank you! Mushrooms have a lot of water - good point, I should have added that in the notes. I cooked them on a rack, so all the excess water dripped on the cooking tray 😊
I love feta - you can use it instead of the blue cheese. And I would maybe use oregano instead of thyme - it goes better with feta 😊
