I know what you’re thinking when you see this recipe. Calamari isn’t kosher, so how can we make this beloved appetizer work for a kosher kitchen? The answer lies in a brilliant substitution that I discovered at a Mediterranean restaurant in Tel Aviv. They use king oyster mushroom stems to create rings that have the exact same texture and mild flavor as squid.
King Oyster Mushrooms: The Perfect Calamari Substitute
The trick is slicing the thick stems into perfect rings and using a double coating technique. First, you dust them in seasoned flour, then dip in beaten eggs, and finally coat with panko breadcrumbs mixed with Italian herbs. The result? Crispy golden rings that fool even the biggest calamari fans. I’ve served these at Shabbat dinners and nobody guessed they weren’t eating seafood.
Getting That Restaurant-Style Crunch
Getting the oil temperature right is crucial for that perfect crunch. I use a candy thermometer and keep the oil at exactly 375°F. Any cooler and your rings get soggy. Any hotter and they burn before the inside cooks through. The marinara sauce comes together while the oil heats up, and I like mine with extra garlic and a pinch of red pepper flakes.
These mock calamari rings work beautifully as an appetizer before a fish dinner or alongside a big salad for lunch. They’re also fantastic for parties because you can prep the rings hours ahead and fry them right before serving. Kids love them too, especially when you serve the marinara in small bowls for dipping.

Ingredients
Method
- Heat olive oil in a medium saucepan over medium heat. Add minced garlic and cook for 30 seconds until fragrant.
- Add crushed tomatoes, oregano, basil, salt, and red pepper flakes. Bring to a simmer and cook for 15 minutes, stirring occasionally.
- Remove from heat and stir in lemon juice. Keep warm while preparing the calamari rings.
- Remove caps from king oyster mushrooms and reserve for another use. Slice the thick stems crosswise into 1/2-inch thick rings.
- Set up three shallow dishes: In the first, combine flour, garlic powder, onion powder, paprika, salt, and pepper. In the second, place beaten eggs. In the third, mix panko breadcrumbs with oregano and basil.
- Heat oil in a heavy pot or deep fryer to 375°F. Use a candy thermometer to monitor temperature.
- Working with a few rings at a time, dredge each mushroom ring in seasoned flour, dip in beaten eggs, then coat thoroughly with seasoned breadcrumbs. Press gently to help coating stick.
- Fry coated rings in batches for 2-3 minutes until golden brown and crispy. Don't overcrowd the pot.
- Remove with a slotted spoon and drain on paper towels. Season immediately with a pinch of salt.
- Serve hot mock calamari rings immediately with warm marinara sauce for dipping. Garnish with fresh basil leaves if desired.
