30-Minute Herb-Stuffed Mushrooms
jump toRECIPE
Herb-stuffed mushrooms may not be the flashiest, most photogenic appetizer, but they’re undeniably delicious! Make these for a crowd-pleasing vegetarian bite perfect for any gathering. The garlicky, herb and breadcrumb filling is inspired by the subtle anise notes of classic escargot butter, giving each mushroom a rich, aromatic flavor. With just a handful of inexpensive ingredients and under 30 minutes of prep and cook time combined, they’re the perfect easy holiday appetizer that always disappears fast. Serve alongside other easy appetizers like marinated olives and feta or green olive tapenade.
Why You’ll Love This Recipe
- Big flavor, simple ingredients. A handful of pantry staples transforms into a rich, buttery, herb filling inspired by escargot.
- Ready in under 30 minutes. Quick to assemble and quick to bake! They are perfect for last-minute entertaining.
Key Ingredients in This Recipe
- Mushrooms – Choose mushrooms similar in size so they cook evenly.
- Garlic – Cooking the garlic in the butter mellows the flavor. Cooking it too long can give it a bitter taste so keep an eye on it.
- Shallots – Shallots have a mild, slightly sweet flavor used to round out the breadcrumb filling.
- Lemon juice – A touch of lemon juice adds just enough acid to balance the rich buttery flavor.
- Herbs – I use a combination of parsley and chives as well as tarragon for a bit of anise flavor to make the filling resemble escargot filling. Fresh herbs are best, though a bit of dried herbs can be substituted if needed.
A full ingredient list with exact amounts can be found in the recipe card below.
Pro tip
Don’t wash the mushrooms! Mushrooms absorb water quickly, which can make them soggy. Instead, wipe them clean with a damp paper towel.
Swaps and substitutions
- Mushrooms: While I prefer the earthy flavor of baby bella (cremini mushrooms) you can use white button mushrooms for a milder flavor. You can also use baby portobellos for a richer flavored appetizer or larger portobellos for an entree.
- Shallots – If needed, swap the shallots for yellow onion.
- Lemon juice: The lemon juice can be substituted for a lighter vinegar, like champagne vinegar, to add a bit of acid.
- Herbs: Try adding thyme or rosemary to the breadcrumb topping for warm savory depth.
- Breadcrumbs: I prefer the airiness from the panko breadcrumbs though you can easily replace them with plain Italian breadcrumbs.
- Cheese: Try adding cheese, like Parmesan or Pecorino Romano, for a richer, cheesy filling.
How to Prep Stuffed Mushrooms in Advance
Make the garlic herb breadcrumb filling, then stuff the mushrooms. Add to a platter or baking sheet and cover with plastic wrap, refrigerating up to 1 day in advance. Pop them in the oven just before guests arrive!
How to Make Herb-Stuffed Mushrooms (Step-by-Step)
Heat oven to 425ºF (220ºC). In a small saucepan, add the butter and allow to melt. Add the garlic and shallots and let cook until the shallots are soft, about 5 minutes.
Remove from heat and stir in the lemon juice, parsley, chives, tarragon and breadcrumbs. Season to taste with salt and pepper.
Arrange the mushrooms on a baking sheet, stem-side up. Season with salt. Fill the cap with a spoonful of the breadcrumb mixture.
Bake until the breadcrumb mixture is golden, about 15 minutes. Let cool slightly and serve.
