Portobello Parmigiana Recipe

Wipe the portobello caps clean with a damp paper towel. Remove and discard the stems. If desired, gently scrape out the dark gills with a spoon to reduce moisture and prevent a muddy flavor.

Brush both sides of each cap with olive oil and season lightly with salt and black pepper (about 1/3 tsp salt and 1/6 tsp pepper per cap). Let sit 5 minutes while you assemble the breading station.

Set up three shallow bowls: bowl 1 with flour; bowl 2 with beaten eggs and milk (whisk until combined); bowl 3 with breadcrumbs mixed with grated Parmesan, dried Italian seasoning, and garlic powder.

One at a time, dredge each mushroom cap: press into the flour, shaking off excess; dunk into the egg mixture, letting excess drip back into the bowl; press firmly into the breadcrumb mixture so the surface is well coated. For a thicker crust, repeat the egg and breadcrumb step once more.

Place breaded caps on a wire rack or a plate and let them rest 5–10 minutes to set the coating. This helps it adhere during frying.

Pour vegetable oil into a large skillet to reach about 1/8–1/4 inch depth and heat over medium heat until shimmering and a breadcrumb dropped in sizzles (approximately 325–350°F if using a thermometer).

Add the breaded caps, cooking in batches if needed. Fry until golden brown, 3–4 minutes per side. Use tongs to gently press for even contact. Adjust heat as necessary to avoid burning the crust; reduce heat if browning too quickly.

Transfer fried caps to a paper towel–lined plate or wire rack to drain briefly (1–2 minutes). Wipe out excess oil from the skillet if crowded or if you prefer to finish in the oven.

Preheat oven broiler to medium-high (or oven to 425°F / 220°C if you prefer baking). Place caps on a baking sheet or ovenproof skillet, top each cap with ~2–3 tablespoons marinara sauce (spread to cover), then sprinkle ~1/3 cup shredded mozzarella across the three caps (divide evenly).

Broil or bake until the cheese melts and bubbles and the edges brown slightly, about 2–5 minutes under a broiler (watch carefully) or 8–10 minutes at 425°F.

Remove from oven and let rest 1–2 minutes. Garnish with fresh basil leaves torn over the top and a light sprinkle of extra grated Parmesan if desired. Serve hot.
