Ingredients
- Mushrooms: I used large portobello mushrooms for this recipe, so they are great to serve as a sit down appetizer or side. Use smaller baby bella mushrooms if you prefer a finger food appetizer.
- Tomato puree: A little tomato puree is brushed onto the mushrooms for another layer of flavor.
- Cheese: We use a mix of ricotta, stilton and parmesan to top the mushrooms.
- Mustard: A little dijon mustard adds a great tang to each bite.
- Breadcrumbs: Panko breadcrumbs add a great crunchy texture to contract with the soft mushrooms and filling.

Frequently Asked Questions
These stuffed portobello mushrooms are best served warm out of the oven, but you can certainly prep them ahead of time. You can stuff the mushrooms and add the breadcrumbs up to a day ahead of time and keep them covered in the fridge until you are ready to bake them.
If you do have leftovers, they will keep for 2 to 3 days and can be reheated in the oven at 350F until warmed through to serve.
These make for a great dinner party appetizer, served on a bed of fresh salad leaves like arugula or baby spinach. They can easily be served up as a tasty side dish too, and they make a great accompaniment to a marinated steak or baked rosemary chicken.
Your mushrooms will need a good clean before you stuff and bake them to remove any loose dirt. Because mushrooms are super absorbent, it's best not to submerge them in water. Instead, use a damp cloth or paper towel to wipe them.
Alternatively, if your mushrooms have a fairly thick skin, you can easily peel this off before baking them.
Recipe Notes and Tips
- I prefer to leave the gills of the mushrooms intact, but you can remove them before stuffing if you prefer.
- Don't brush the mushrooms with too much oil, you just need a little bit. If you add too much, the mushrooms can become soggy.

I just made this for my wife, a vegetarian, and she loved it. It's certainly tasty, and the Ricotta really balances out the strength of the blue cheese. She thought it the best stuffed mushroom she had ever had. The recipe doesn't say how much mustard to use, but mentions it in the process. I used 2/3 tsp of Dijon. Thanks.

Hi Ewan, so glad you and your wife enjoyed this 🙂 Thanks for noting about the mustard missing from the ingredients, I've adjusted the recipe to reflect the amount! Thanks!
