Storage/Reheating
If you have leftovers, store them in an airtight container in the refrigerator. To reheat, warm gently in an oven or toaster oven — this helps retain crispiness. Mushrooms can also be eaten cold, though texture will be softer.
FAQs
What type of mushrooms work best for this recipe?
Large white mushrooms work great because their size and texture hold up well under baking. You can also try cremini mushrooms or other firm varieties — just adjust cooking time if they’re smaller.
Do I need to peel the mushrooms?
Yes — the recipe recommends peeling the mushroom caps before halving. This helps seasonings stick better and improves texture.
Can I skip the freshly grated Parmesan step?
You could, but the freshly grated Parmesan adds a nice cheesy crust and stronger flavor. The dish still works with only the mixed Parmesan — it will just be milder.
What if my mushrooms seem dry when coating?
If the mushrooms seem dry after tossing with the initial oil and Parmesan mix, add a little more olive oil and stir again — this will help them roast more evenly.
Can I use pre-shredded Parmesan instead of freshly grating?
Yes — pre-shredded Parmesan works; just know that freshly grated tends to melt and crisp more evenly, giving a slightly better texture.
Is this recipe gluten-free / vegetarian?
Yes — it’s naturally vegetarian, and as long as your Parmesan cheese is gluten-free (which most are), the recipe can also be gluten-free.
Can I make this recipe ahead of time?
You can prep mushrooms (clean, halve, coat) ahead but wait to bake until you’re ready to serve for best texture.
What’s a good dip to serve with these mushrooms?
A creamy dip like Tzatziki works well; you can also use garlic aioli, yogurt-based sauce, or even a simple herbed cream cheese — whatever you prefer.
Can I adjust the seasoning to be spicier or milder?
Absolutely. You can increase or decrease the chili flakes, or skip them entirely if you prefer milder flavor. You can also experiment with different herbs or spices based on your taste.
How many mushrooms count as one serving?
This recipe yields 4 servings using about 20 oz of mushrooms total. Serving size will depend on appetite and what you serve them with but generally a quarter of the batch per person works well.
