What kind of mushrooms are best for stuffing?

Larger mushrooms with wide caps, like cremini or button mushrooms, are ideal for stuffing. Portobello mushrooms also work well for a larger, more substantial appetizer.

Can I make stuffed mushrooms ahead of time?

Yes, you can prepare the mushrooms and stuffing ahead of time. Store them separately in the refrigerator, and then stuff and bake them just before serving for the best texture. Alternatively, you can fully assemble and refrigerate, adding a few minutes to the baking time.

What can I use instead of breadcrumbs in the stuffing?

If you're looking for a gluten-free option, try using crushed pork rinds, almond flour, gluten-free breadcrumbs, or finely grated parmesan cheese in place of breadcrumbs.

How do I prevent stuffed mushrooms from becoming soggy?

To avoid soggy mushrooms, make sure to remove the stems and gently wipe the mushroom caps clean instead of washing them. Pre-cooking the mushroom caps in a dry pan before stuffing can also help release excess moisture.

What are some variations I can make to the stuffing?

You can add cooked sausage, bacon, or finely chopped vegetables like onions, peppers, or spinach to the stuffing for added flavor and texture. Different herbs like thyme or rosemary can also change the profile.

How long do leftover stuffed mushrooms last?

Leftover cooked stuffed mushrooms should be stored in an airtight container in the refrigerator and consumed within 3-4 days. Reheat thoroughly before serving.

Instructions

Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper. Wipe mushrooms clean, remove stems, and finely chop about 1/2 cup of stems. Place caps on the sheet.
In a skillet over medium heat, melt butter with olive oil. Add onion and chopped mushroom stems. Cook 5-7 minutes until soft and liquid evaporates. Add garlic and cook 1 minute more. Remove from heat and cool slightly.
In a bowl, combine cream cheese, 1 cup Irish cheddar, Parmesan, breadcrumbs, parsley, thyme, smoked paprika, pepper, and salt. Add the cooled onion mixture and stir until cohesive.
Generously fill each mushroom cap with the cheese mixture, mounding slightly. Sprinkle with the remaining 1/2 cup Irish cheddar.
Bake for 18-22 minutes until mushrooms are tender and cheese is golden and bubbly. Cool 2-3 minutes, garnish with parsley, and serve warm.

Notes

For best results, grate cheese from a block. Filling and cleaned mushrooms can be prepped a day ahead. To freeze unbaked, freeze stuffed caps solid on a sheet, then transfer to a bag; bake from frozen at 375°F for 25-30 minutes.
