I roasted oyster mushrooms until they got so outrageously crispy and meaty that even my mushroom-hating cousin was stunned, and yes, Shredded Oyster Mushrooms pull off the same trick.

Jump to Recipe

I’m obsessed with roasted crispy oyster mushrooms. I love how shredded oyster mushrooms turn into insanely crunchy, chewy bites that you keep grabbing even after you say you’re done.

I crave that hit of garlic powder and salted char, the kind that makes fries jealous. But it’s not just texture, it’s attitude.

Meaty, slightly smoky, stupidly snackable. I eat them straight from the tray, sometimes with a napkin and zero shame.

Oyster mushroom gravy? Yes please, for dunking.

No pretending this is fancy. It’s loud, simple, and exactly what I want to eat right now, every time.

no regrets, seriously.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly oil it so the mushrooms dont stick.

2. Tear 1 lb oyster mushrooms into bite sized pieces, try to keep similar sizes so they cook evenly.

3. In a large bowl whisk together 2 to 3 tablespoons extra virgin olive oil, 1 tablespoon soy sauce or tamari, 1 tablespoon fresh lemon juice, 1 teaspoon garlic powder, 1/2 teaspoon smoked paprika, 1 teaspoon kosher salt and 1/2 teaspoon black pepper.

4. Add the mushrooms to the bowl and toss gently to coat. Let sit 5 minutes so the flavors soak in.

5. Sprinkle 2 tablespoons cornstarch over the mushrooms and toss again until lightly dusted. If you want extra crunch, add 1/2 cup panko breadcrumbs and toss to combine. The cornstarch helps make them super crispy.

6. Spread the mushrooms in a single layer on the prepared sheet, dont overcrowd. Use two sheets if needed so each piece gets crisp.

7. Roast on the middle rack for 10 to 12 minutes, then flip or shake the pan and roast another 8 to 12 minutes until edges are golden and crispy. If you have convection mode use it for extra crispness.

8. When theyre done, immediately toss with 2 tablespoons chopped fresh parsley and 2 tablespoons grated Parmesan cheese if using, so the cheese melts a little and sticks.

9. Serve hot with lemon wedges for squeezing over. Tip: if they soften after sitting, re-crisp in a hot oven for 3 to 5 minutes before serving.

Equipment Needed

1. Rimmed baking sheet (or two if you want extra space)
2. Parchment paper or a light coating of oil and a pastry brush
3. Large mixing bowl
4. Whisk (or fork, if thats what you have)
5. Measuring spoons and a 1/4 or 1/3 cup measure for the cornstarch/panko
6. Tongs or a large spoon for tossing the mushrooms
7. Kitchen knife and cutting board for tearing/trimming mushrooms and chopping parsley
8. Oven mitts and a cooling rack or another sheet to shake/flip the mushrooms

FAQ

Q: Can I use other mushrooms if I can't find oyster mushrooms? A: Yes, you can. King oyster, shiitake or cremini work well. Texture and cook time might change a little, so watch for crisp edges and not soggy centers.

Q: Do I really need the cornstarch and panko? A: Cornstarch is the key to crispiness, panko is optional for extra crunch. If you skip panko, just bump the cornstarch a tiny bit and pat pieces well before oiling.

Q: What's the best way to get them evenly crispy in the oven? A: Spread mushrooms in a single layer on a lined baking sheet and don't overcrowd. Flip once halfway through. If they steam, they won't get crispy.

Q: Can this be made gluten free or vegan? A: Yep. Use gluten free panko or skip it, and swap soy sauce for tamari. Skip Parmesan to keep it vegan or use a vegan parm.

Q: How do I store and reheat leftovers? A: Store in the fridge up to 3 days in an airtight container. Reheat in a hot oven or air fryer for a few minutes to bring back crunch. Microwave will make them soggy.

Q: Any flavor tips to change it up? A: Try a pinch of cayenne for heat, drizzle a little sesame oil after roasting for nuttiness, or toss with chili garlic sauce for a sticky glaze. A squeeze of lemon right before serving brightens everything up.

Roasted Crispy Oyster Mushrooms Recipe Substitutions and Variations

Extra virgin olive oil: use avocado oil (higher smoke point) or neutral vegetable oil like canola if you want less flavor, or melted coconut oil for a slight sweet note.
Cornstarch: swap with arrowroot powder for a lighter crisp, or use rice flour or all purpose flour if thats what you have on hand.
Panko breadcrumbs: replace with crushed cornflakes or regular dried breadcrumbs, or try finely chopped nuts for a nutty crunch.
Soy sauce or tamari: substitute coconut aminos for a gluten free, lower sodium option, or use Worcestershire sauce in a pinch (it changes the flavor a bit).

Pro Tips

1. Pat the mushrooms dry with paper towels before you toss them, seriously. Wet shrooms steam not crisp, so even a little extra drying makes a big difference.

2. Don’t pile them on the sheet, use two pans if you gotta. Crowding = soggy, and flipping once halfway works better than poking them every minute.

3. If you want extra crunch, mix the panko in right before baking not earlier otherwise it soaks up the marinade and goes limp. Also, a light dusting of cornstarch is the secret, dont overdo it or they’ll feel powdery.

4. Serve hot and squeeze lemon just before eating. They crisp up fast once cooled, but 3 to 5 minutes in a hot oven brings them back to life if they sit too long.
