How to Make Spinach & Feta Stuffed Portobellos

Preheat your oven to 400°F and line a baking sheet with parchment paper. This ensures even cooking and easy cleanup.
Prepare Mushrooms: Gently wipe caps clean and remove stems; brush with olive oil and season with salt and pepper for better flavor.
For the Filling:
Sauté a splash of oil over medium heat; gently cook onion and garlic until soft and fragrant, about 3 minutes.
Wilt Spinach: Add fresh spinach, cooking until bright green and wilted, around 2 minutes, then season lightly with salt and pepper for balance.
Mix Filling: Transfer the spinach mixture to a mixing bowl; stir in crumbled feta, breadcrumbs, and lemon zest until thoroughly combined for a creamy, cohesive filling.
Stuff Caps: Spoon the filling into each portobello cap, pressing gently so it holds together neatly and sits level with edges for even browning.
Bake: Arrange stuffed mushrooms on the sheet; roast for 15–18 minutes, until caps are tender and filling is golden and bubbling around edges.
Garnish & Serve: Sprinkle with chopped parsley or red pepper flakes for extra color and a flavor boost right before serving for freshness.

Optional: Drizzle with balsamic glaze for a sweet-tangy finish.

Expert Tips for Spinach & Feta Stuffed Portobellos

Choose Fresh Mushrooms: Select firm, large portobello caps for best texture and flavor—avoid those with wrinkles or soft spots.
Don’t Overcook Spinach: Wilt spinach just until bright green to keep its vibrant flavor and prevent sogginess in your filling.
Balance Seasoning: Taste the filling before stuffing and adjust salt and pepper; feta is salty, so season cautiously.
Press Filling Evenly: Pack the spinach and feta mixture firmly but evenly in each mushroom so it holds shape and browns beautifully.
Monitor Baking Time: Overbaking dries out mushrooms; roast just until tender and filling bubbles for a perfect hearty bite.

Spinach & Feta Stuffed Portobellos Recipe FAQs

How do I know if my portobello mushrooms are fresh and ready to use?
Look for large, firm caps without any dark spots or bruises. Avoid mushrooms that feel slimy or have wrinkled skins, as those are signs they are past their prime. Fresh portobellos should be heavy for their size and have a pleasant earthy aroma.

Can I store leftover Spinach & Feta Stuffed Portobellos in the refrigerator?
Absolutely! Place leftovers in an airtight container and keep them in the fridge for up to 3 days. When ready to enjoy again, gently reheat them in a 350°F oven until warmed through to preserve their juicy texture and vibrant flavors.

What’s the best way to freeze these stuffed mushrooms?
Freezing is a great option! Wrap each stuffed portobello individually in plastic wrap to prevent freezer burn, then place them in a freezer-safe bag or container. They’ll keep well for up to 2 months. To reheat, thaw overnight in the fridge and bake at 375°F for about 20 minutes until hot and bubbly.

My filling turned out soggy—how can I avoid this?
This can happen if the spinach is overcooked or if too much moisture is left in the filling. To fix it, make sure to wilt the spinach just until bright green, then squeeze out excess liquid with a clean kitchen towel before mixing with the other ingredients. Also, press the filling firmly and evenly into the mushroom cap to help it brown nicely.

Are Spinach & Feta Stuffed Portobellos safe for pets, or are there ingredients I should avoid?
While mushrooms themselves can be safe in moderation, feta cheese and garlic aren’t recommended for pets as they can cause digestive upset or be toxic. It’s best to keep this dish for your table only and offer your furry friends pet-safe treats instead!
