Step 4: Fry
Heat oil in a deep skillet or Dutch oven to 350°F. Fry mushrooms in small batches—avoid crowding the pan, which can lower the temperature and make them greasy. Cook 3–4 minutes, turning once or twice, until golden brown and crisp.
Step 5: Drain and Serve
Use a slotted spoon to transfer mushrooms to a paper towel–lined plate to remove excess oil. Serve immediately while the coating is at its crispiest.
