Recipe by Mark Calaminici | Food Loves Company

Serves 2-4


2 lb or 800g Cremini mushrooms (or any mushroom you like), cleaned, stems trimmed or removed

3 tbsp. extra virgin olive oil

Salt, to taste

Freshly cracked pepper, to taste

Mushroom juice (about 3 tbsp. or to taste)

1 garlic clove, smashed

3 tbsp. unsalted butter

Chili flakes, to taste

2-3 tbsp. or 5g fresh tarragon, finely chopped

½ tbsp. lemon juice

Parmigiano-Reggiano, to taste


1. Preheat oven to 400 degrees.

2. In a large bowl, add mushrooms with extra virgin olive oil and season with salt and freshly cracked pepper. Toss to incorporate all ingredients.

3. Transfer mushrooms to a baking sheet lined with tin foil if you like. Place in oven and roast for 50-60 minutes, until nicely browned. After about 20 minutes of roasting, remove the mushrooms and do your best to remove as much as the mushroom juice that has formed and place in a bowl. Then add the mushrooms back in the oven to roast. Depending on how much mushroom juice you have removed, you will want about 3 tbsp. worth. Any extra can be used for soups, stock or whatever else you like, it’s great flavour.

4. In a large frying pan over medium heat, add the mushroom juice, garlic, butter, lemon juice and tarragon. Once everything has melted and has reduced a bit, bring the heat down to low and let it continue to reduce and simmer until the mushrooms are done. Removing the garlic is optional.

5. Just before removing the mushrooms, take them out and finely grate as much Parmigiano-Reggiano as you like all over the mushrooms. Place back in the oven and let the cheese melt, brown and crisp up. Once mushrooms are done, remove and place in a large bowl, add the garlic and tarragon butter and toss to incorporate all ingredients. Plate and garnish with any extra sauce and fresh tarragon. Enjoy.
