How to Make Thanksgiving Stuffed Mushrooms

1. Prep the mushrooms: Heat the oven to 400°F (200°C). Wipe the mushrooms clean with a damp paper towel.Twist out the stems, reserving them. Lightly toss the caps with 1 tablespoon olive oil and a pinch of salt. Arrange them cavity-side up on a parchment-lined baking sheet.
2. Chop the stems: Finely mince the mushroom stems so they cook quickly and blend smoothly into the filling.
3. Cook the aromatics: In a skillet over medium heat, melt the butter with the remaining tablespoon of olive oil.Add the onion and cook until soft and translucent, about 4–5 minutes.
4. Build flavor: Add the chopped stems, salt, black pepper, and red pepper flakes (if using). Cook until most of the moisture evaporates, 5–7 minutes. Stir in the garlic and cook 30–60 seconds until fragrant.
5. Combine the filling: Transfer the mixture to a bowl.Add cream cheese, Parmesan, breadcrumbs, parsley, thyme, and lemon juice. Mix until creamy and well combined. If using sausage, bacon, or spinach, fold them in now.

   Taste and adjust seasoning.

6. Stuff the caps: Spoon a rounded heap of filling into each mushroom. Press lightly to secure. Sprinkle a little extra Parmesan on top for a golden finish.
7. Bake: Bake for 15–18 minutes, until the mushrooms are tender and the tops are lightly browned.If you like a deeper color, broil for 1–2 minutes at the end.
8. Finish and serve: Let them rest for 3 minutes. Sprinkle with fresh parsley and serve warm. Add a squeeze of lemon if you want a brighter finish.

Common Mistakes to Avoid

• Skipping the moisture cook-off: If you don’t cook the stems and onions long enough, the filling can turn watery.
• Overcrowding the pan: Give mushrooms space on the baking sheet so they roast instead of steam.
• Using wet mushrooms: Don’t soak them. Wipe with a damp towel to avoid sogginess.
• Underseasoning: Taste the filling before stuffing and adjust salt and lemon to brighten the flavor.
• Overbaking: Mushrooms should be tender but not collapsed. Check at 15 minutes and adjust from there.

FAQ

Which mushrooms are best for stuffing?

White button and cremini mushrooms hold their shape and have the right size for finger food. Cremini (baby bella) have deeper flavor, while button mushrooms are milder and slightly juicier.

How do I keep stuffed mushrooms from getting soggy?

Cook the stems and aromatics until most moisture evaporates, and don’t wash the caps under running water. Roast at a hot temperature and avoid overcrowding the pan so steam can escape.

Can I make these ahead for Thanksgiving?

Yes.

Assemble the stuffed mushrooms up to a day in advance. Cover and refrigerate, then bake right before guests arrive. Add a couple minutes to the bake time if they’re cold from the fridge.

What can I use instead of cream cheese?

Go for mascarpone or goat cheese for a tangy twist.

For a lighter option, use ricotta and add extra Parmesan and breadcrumbs for structure.

How many should I plan per person?

For a Thanksgiving appetizer spread, plan on 3–4 mushrooms per person if you have other options, or 5–6 per person if these are the main starter.

Can I serve them at room temperature?

They’re best warm, but they hold up at room temperature for about 45–60 minutes. If they cool down, pop them back in a warm oven for a few minutes to refresh.

Do I need to remove the gills?

No. Button and cremini mushrooms have shallow gills that don’t need removing.

Just twist out the stems and you’re good to go.
