I always find myself eating a few right off the tray before they hit the table The fresh rosemary reminds me of my grandmother’s herb garden and fills me with nostalgia
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to five days To reheat use a skillet over medium heat just until warmed through This keeps the texture tender instead of rubbery For longer storage freeze roasted mushrooms in a single layer first then transfer to a bag and keep frozen for up to six months You can reheat them straight from the freezer
Ingredient Substitutions
Feel free to swap baby portobello mushrooms for white button mushrooms shiitake or even a mix for added variety If you do not have fresh herbs dried will still give great taste Use one third the amount as dried is more concentrated Dairy free or vegan Try substituting all olive oil or a plant based butter alternative
Serving Suggestions
These roasted mushrooms pair with steak roast chicken or a simple omelet For an easy starter pile them onto crusty bread with a sprinkle of parmesan I have also added them to salads pasta or folded them into risotto for a quick flavor boost

Commonly Asked Questions
- → How do I keep mushrooms from getting soggy when roasting?
Roast mushrooms at a high temperature, like 400°F, so excess moisture evaporates quickly. If there's liquid in the pan midway through cooking, carefully drain it off for a crispier texture.
- → Do I need to wash mushrooms before roasting?
Yes, a quick rinse under running water is fine. Pat mushrooms thoroughly dry before roasting to avoid extra moisture in the pan.
- → Can I use dried herbs instead of fresh?
Absolutely! Dried herbs like thyme or rosemary work well—use about one-third of the amount you’d use for fresh, since dried herbs are more concentrated.
- → What's the best way to reheat leftover roasted mushrooms?
Warm leftovers gently in a skillet over low to medium heat, stirring often. Avoid overheating, as this can make mushrooms rubbery.
- → Can cooked mushrooms be frozen?
Yes! Freeze roasted mushrooms in a single layer before transferring to a container. Reheat them straight from the freezer for best results.
- → What kind of mushrooms work best?
Baby portobello or cremini mushrooms are ideal, as they hold their shape and absorb flavors well, but button mushrooms also work nicely.
