Portobello Mushroom Salad with Feta & Micro Greens (Roasted, Hearty, 25 Minutes)
This portobello mushroom salad is a meaty, smoky and earthy recipe accompanied by delicate micro leaves, crunchy pistachios and finished off with a lemon parsley vinaigrette. An easy way to serve up a fancy salad for a special occasion!
If You Love Big, Meaty Mushrooms, This Salad Is for You
Portobello mushrooms have such an earthy and smoky flavour. They are also fantastic due to their size, and you can do so much with them. Serving it up as it is and adding a few little elements really lifts it.
This salad has been created as an individually plated salad that can be served as a small appetiser or served at the same time as the main fare.
As the mushrooms are so big, it is easier served on a dish on its own instead of having to share with the other dishes on the table.
By serving it up individually, it allows us to play with its presentation. It’s an easy plate up of just a few splashes of dressing and sprinkling and crumbling of ingredients.
The results are surprisingly pretty, and it’s one of those deceivingly easy salads where people think it takes a lot of effort. Love those recipes!
They are also great for Christmas if you’re thinking of serving up a fancy starter!
Roasted portobello mushrooms topped with micro salad leaves, feta crumbles, pistachios, and a lemon parsley vinaigrette. A warm, textural portobello mushroom salad that feels substantial but stays fresh.
Recipe Overview
Flavour/Texture: The salad is earthy and smokey with the added delicate flutters of the micro salad, saltiness from the feta cheese and the crunchy nuttiness from the pistachios.
We drizzle a lemon parsley vinaigrette to round it off, which as you can imagine is herbaceous and citrusy. This enhances the flavours of the other ingredients.
Ease: Simple! Whack the mushrooms in the oven. Blitz the salad dressing and then assemble. You can play around with the presentation of the salad itself to suit your liking. Have fun with it!
Time: 10 minutes for prep and assembly with 15 minutes in the oven. In fact, if you’re organised you can shorten this time by doing some of the prep while the mushrooms are roasting away.
Ingredients for Portobello Mushroom Salad
Portobello mushrooms: Make sure you’re choosing the best quality mushrooms you can find. As they are so delicate and not the cheapest of fresh produce, check the underside that it’s not slimy or overly soft.
Pistachio kernels: to add to the mushroom’s earthy flavours, the pistachios helps to enhance it. It has been said that pistachios have a mild flavour, but I personally don’t think so.
Of all the nuts, pistachios have the most distinct taste. Hence fantastic for salad recipes. Oh and let’s not forget the crunch. We want the crunch!
Feta: Included for all of its creamy, salty goodness. As you cut through the mushroom and you pick up the micro salad and pistachios, smash some of the feta on top to bind it all together for the perfect mouthful!
Micro salad: Delicate, fresh and soft, it gives the recipe the contrast in textures to the meaty mushrooms.
Besides, they’re such a healthy addition and also provide some height to the plate.
Parsley: A fantastic staple herb to use for a salad dressing. When you lift the lid of your food processor, you’ll be hit with the strong smells of this fresh herb. Not to mention a great way to add some greens to your diet!
Olive oil: Use your favourite olive oil for this recipe.
Lemon: This recipe needs some citrus. Otherwise, it’s too earthy and salty. The lemon helps to cut through it and give it that little bit extra that it needs.
Red wine vinegar: Can’t have a vinaigrette without some vinegar!
Garlic clove: Garlic tends just to give any recipe that little extra boost. Incorporated into the lemon parsley vinaigrette, it gives the dressing extra flavours.
Large portobello mushrooms provide a meaty, umami-rich base, while micro salad leaves add freshness and contrast. Pistachios bring crunch, feta crumbles add salty creaminess, and the lemon parsley vinaigrette cuts through the richness with acidity and herbs.
Variations and Substitutions
No micro salad: If you’re unable to find micro salad, you can use any micro herb such as red stem radish, dark opal basil or garnet giant mustard.
Alternatively, you can use sprouts. Mung bean would probably be my last choice with my favourite being the snow pea or alfalfa sprouts.
Nut alternative: You can use pine nuts, almonds or hazelnuts if you prefer or just have them handy in your pantry. For those with any nut allergy, replace it with sunflower seeds or pepitas.
Vegan friendly: Replace dairy component with vegan feta. The tofu truly works a treat!
Parsley substitute: Coriander would be the perfect substitute for this salad dressing. Sometimes I change it up as I have so much coriander leftover!
Add grains: Serve the mushrooms over farro, barley, or lentils to turn this into a more filling salad.
Boost the greens: Replace micro salad leaves with arugula or baby spinach for a bolder, peppery bite.
Add sweetness: A drizzle of honey or balsamic glaze can soften the earthy mushroom flavours if desired
Instructions for Portobello Mushroom Salad
How to Make Salad
Preheat the oven at 180°C or 350°F and baste a sheet pan with 1 tbsp of olive oil.
Remove the stem from the mushrooms. Be gentle with this process as you don’t want to break the mushroom.
You can squeeze the stem which will loosen it from the base and also allow you to remove smaller chunks at a time. Or you can give it a little push left and right until it naturally lifts from the base.
Lay the mushrooms skin side down and baste with 1 tbsp olive oil and season with salt and pepper. Place in the oven for 15 minutes.
Roughly chop 20g of pistachios. Leave the other 20g whole.
Crumble the feta.
Wash micro salad and ensure dry before use.
How to Make Lemon Parsley Vinaigrette
Roughly chop parsley leaves and add into a food processor.
Then add olive oil, juice of ¼ lemon, red wine vinegar, garlic clove and salt.
Blitz until well combined.
How To Assemble The Salad
This is an individually plated salad, so repeat this process 4 times.
Drizzle some lemon parsley vinaigrette randomly on the plate. If you have any leftovers, place in a small bowl and serve with dinner so you can add more if you wish.
Place one mushroom, skin side down on one side of the plate.
Place a heap of micro salad on top of the mushroom.
Sprinkle some crumbled feta and whole pistachios on the plate.
Sprinkle some chopped pistachios on top of the mushroom and around the plate.
Season with salt and pepper to taste.
Repeat for the other 3 plates.
Serve.
The portobello mushrooms are roasted until tender and juicy, then plated individually with micro salad leaves, feta, and pistachios. A quick lemon parsley vinaigrette is blended and drizzled over the salad just before serving.
How To Make This Salad Perfectly [Expert Tips]
Mushrooms: Choose mushrooms that are firm and fresh. Removing the stems helps the mushrooms lay flat and roast evenly.
Basting with olive oil and seasoning with salt and pepper ensures they are flavorful.
Consider adding a pinch of garlic powder or thyme for added flavour.
Roasting at 180°C or 350°F for 15 minutes should make them tender, but keep an eye on them to avoid overcooking.
Don’t overcrowd the tray: Space allows the mushrooms to roast rather than steam, improving flavour and texture.
Feta: Use high-quality feta cheese for the best flavour. We do prefer traditional Greek feta for our recipes.
Micro salad: Wash thoroughly and dry completely using a salad spinner or patting with paper towels to prevent the salad from becoming soggy.
Dressing: Use fresh parsley leaves for a vibrant flavour. When adding ingredients to the food processor, ensure they are well-balanced; adjust seasoning if necessary.
Blitz the dressing until smooth, but if you prefer a bit more texture, pulse until combined but still slightly chunky.
Let the roasted portobello mushrooms rest for 5 minutes before plating — this allows the juices to redistribute and keeps the mushrooms succulent when cut into.
Frequently Asked Questions
To prevent your mushrooms from going slimy, you can do a few things.
Always buy your mushrooms individually rather than in a sealed pack. This way you can touch the mushrooms and check them to see if they are already starting to deteriorate.
This allows you to pick the best quality, especially important if you’re not cooking it on the day.
Mushrooms are made up of 80% to 90% water so storing them in paper bags is essential as it will allow it to breathe.
Putting them in an airtight container increases the rate of spoilage as condensation occurs. Storing them in the fridge also helps to prolong its longevity.
There are 2 ways you can remove the stem.
The first and probably most common way is to lay the mushroom stem side up. Using your thumb give it a little nudge on each side, and eventually, the stem will come away from the cap. Don’t yank it too hard or it will break.
As the portobello mushrooms are so big, you can use a small sharp knife to cut the stem off.
They may not be so easy to wriggle off. This way it’s a clean-cut and you won’t have to worry about breaking the mushroom. As it’s the hero of the dish, you do want it intact!
Micro salads, microgreens and micro herbs haven’t quite made its way to mainstream supermarkets as yet where I am. I go to fine food grocers or farmers markets to get them.
If you have any leftovers, just add them as a garnish to your next meal or throw it into a simple salad mix.
Even though this is an individually plated salad, it can, of course, served all on a platter. Select a bigger platter than required to house the recipe. This gives it some white space to just help with the presentation.
Place the mushrooms haphazardly on the platter. No right or wrong way of doing this and just follow the rest of the assembly instructions.
You can prepare all the components in advance but leave the roasting of the mushrooms to the end. This is a warm salad, and it wouldn’t be good cold.
Told you it was easy! Would you have thought this process would yield these results? With such beautiful produce, you don’t have to do much to elevate it that’s for sure! Make sure to eat the mushroom with everything on the plate.
This portobello mushroom salad was tested by The Sidesmith team to get the balance right between deeply roasted mushrooms and fresh, contrasting elements.

Love turning everyday salads and sides into fancy recipes jammed packed with flavour!
This portobello mushroom salad came together faster than expected—hearty, fresh, and filling enough to stand on its own.
This was sooo good! I used raw sunflower seeds instead of pistachios, I am not a fan of raw garlic, so I used garlic powder instead. I also added artichoke hearts. Will definitely make it again!
Awwww amazing! Thank you for your lovely comment. Great idea with the substitutions and additions!
I have never tried to make this salad, and it looks so delicious!
I will be saving this and will add this to our lists of dishes for our Mother’s Day celebration.
Hope it was a hit Amy
I used follow your heart’s vegan feta instead of regular and it worked great! Such a delicious recipe
Great to know Jacqui! Always looking for flavoursome vegan alternatives for your followers.
I would have never thought of portobello in a salad form. That is great.
Thanks! Love eating mushrooms in salads and cooking them up in a myriad of ways.
Wow, that color is amazing and I love how you make and serve these portobellos.
Thank you! Just thought we’d change it up a bit:)
