Classic Stuffed Mushrooms Recipe

Here’s a fairly classic, crowd-pleasing version (based on Food Network / Martha Stewart / others).

~12 large mushrooms (button or cremini) — stems removed, roughly chopped (Food Network)
1 tbsp olive oil + a little butter (Food Network)
2–3 garlic cloves, minced (Mom On Timeout)
½ small onion or shallot, finely chopped (Food Network)
4 oz (≈ 115 g) cream cheese, softened (for the creamy filling) (Downshiftology)
~⅓ cup Parmesan cheese (or mix of Parmesan + other cheese) (Downshiftology)
Fresh parsley, chopped, for flavor and garnish (Downshiftology)
Optional: Panko or regular breadcrumbs for texture / crispness (Mom On Timeout)
Salt & pepper, to taste (Mom On Timeout)

Preheat
Preheat your oven to about 375°F (around 190°C) (or as per the recipe you pick). (Food Network)
Prep Mushrooms
- Clean the mushrooms gently (wipe with a damp cloth). (Food Network)
- Remove the stems. Chop the stems finely — you’ll use them in the filling. (Cooking Classy)
Make the Filling
- In a skillet, heat the olive oil + butter. Sauté the chopped mushroom stems, garlic, and onion / shallot until soft. (Food Network)
- Remove from heat and let the mixture cool a little. Then mix in the cream cheese, Parmesan, and parsley. Add salt and pepper to taste. (Hip Hip Gourmet)
- If using, fold in some breadcrumbs to get a better texture / binding. (Mom On Timeout)
Stuff the Mushrooms
- Place the mushroom caps on a baking sheet (gill-side up). (Food Network)
- Spoon the filling into each mushroom cap, packing them lightly. (Food Network)
- Drizzle a little extra olive oil on top (optional) for extra flavor. (Food Network)
Bake
- Bake in the oven for 25–30 minutes, or until the mushrooms are tender and the filling is golden / set. (Food Network)
- If you want a crisp top, you can broil for 1–2 min at the end (watch carefully so it doesn’t burn).
Serve
- Let them cool slightly, then garnish with more parsley (or herbs of your choice).
- Serve warm as an appetizer or side.

Here are some great ways to change the recipe depending on what you like:

Vegetarian / Cheesy Version: Use spinach + cream cheese + Parmesan in the filling. (Mom On Timeout)
Sausage Stuffed: Use Italian sausage + garlic + breadcrumbs + cheese for a meaty filling. (Food Network)
Quinoa Stuffed Portobello: For a healthier twist, stuff large portobello mushrooms with cooked quinoa, sun-dried tomatoes, walnuts, garlic, and herbs. (ucihealth.org)
Indian Style: Use gramflour (besan), curd, spices (garam masala, chilli) + onion + capsicum for a flavor-packed stuffed mushroom. (betterbutter.in)

Use cremini (baby bella) mushrooms if you want more flavor — they’re a bit more robust than plain white mushrooms. (Downshiftology)
Make sure to squeeze out moisture if your filling has spinach, or else it will be watery. (Cooking Classy)
Don’t overstuff — mushrooms shrink a bit when cooked, so a little extra space is okay.
Use fresh herbs if possible — parsley, thyme or oregano work beautifully.
Serve them soon after baking for best texture, but you can also prepare the filling in advance and stuff just before baking.
