How to Make Shrimp-Filled Portobello Mushroom Caps
Prepare the mushrooms
Preheat your oven to 400°F. Remove stems from the mushrooms and set them aside. Gently wipe the caps with a damp paper towel—never soak them, or they’ll get soggy. Finely chop the stems for later.
Initial bake
Place the mushroom caps on a baking sheet. Brush each cap inside and out with 1 tablespoon olive oil, sprinkle with salt and pepper, and bake for 15 minutes. This pre-bake keeps the mushrooms tender without turning them watery.
Don’t skip the pre-bake – This step keeps your mushroom caps firm and prevents watery fillings.
Make the filling
While the caps are roasting, heat the remaining olive oil and butter in a skillet over medium heat. Add chopped stems, green onions, and garlic. Season lightly and cook for 8–10 minutes until tender and fragrant.
Cook the shrimp
Add the chopped shrimp to the skillet. Stir until they turn pink and opaque, about 1–2 minutes. Be careful not to overcook—shrimp can turn rubbery fast. Remove from heat immediately.
Chop shrimp evenly – Smaller, uniform pieces ensure every bite is flavorful and well-mixed.
Combine filling ingredients
Stir in the beaten egg, lemon juice, half the parsley, and half the breadcrumbs until well mixed. The egg will help everything hold together once baked.
Use fresh lemon juice – Bottled lemon juice can be bitter; fresh gives the dish a bright, clean taste.
Stuff and finish baking
Pat any liquid from the baked mushroom caps with paper towels. Spoon the shrimp mixture evenly into each cap, mounding slightly. Sprinkle with the remaining breadcrumbs for that golden crunch. Return to the oven for 10–15 minutes until the tops are golden and the filling is set.
Breadcrumb texture – For extra crunch, toast the breadcrumbs in a dry skillet before sprinkling.
Serve
Garnish with the remaining parsley and lemon wedges. Serve hot and watch them disappear.

Diet-Friendly Options

Gluten-Free – Use gluten-free breadcrumbs or panko.

Pescatarian – Already fits the bill, but you can also try a mix of seafood for variety.
Best Ways to Store
In the fridge – Place cooled mushroom caps in an airtight container and store for up to 3 days.
To reheat – Warm in the oven at 350°F for 10–12 minutes to keep the breadcrumbs crispy.
Freezing not recommended – Mushrooms tend to release too much water after thawing, changing the texture.
Recipe Variations
Cheesy Upgrade – Sprinkle Parmesan, Gruyère, or mozzarella on top before baking.
Spicy Twist – Add a pinch of crushed red pepper flakes to the filling.
Surf & Turf – Mix in some cooked, crumbled bacon for a smoky touch.
Mediterranean Flair – Add chopped olives, sun-dried tomatoes, and feta cheese.
