Why I Like This Recipe
I wasn’t even planning to cook, tbh. Just stared at a pack of mushrooms too long. Had some canned clams. A mess of cheeses in the fridge. And next thing I know? I’m in full Olive Garden cosplay — apron on, garlic everywhere, mushrooms stuffed like my brain after solo queue. 😅 They’re buttery, melty, and weirdly comforting. And not that hard either. Just enough steps to feel like you tried.
Ingredients
- 9 oz mushrooms (whole, not sliced)
- 6 oz clams (canned is fine)
- 1 tbsp chopped green onion
- ½ tsp minced garlic
- ⅛ tsp garlic salt
- ½ cup Italian-style breadcrumbs
- 1 tsp dried oregano
- 1 tbsp butter (melted)
- 1 egg (optional but helps bind)
- 2 tbsp grated Parmesan
- 1 tbsp grated Romano cheese
- 2 tbsp shredded mozzarella
- ¼ cup shredded mozzarella (for topping)
- ¼ cup butter (for baking)
How To Make Stuffed Mushrooms
- Prep your mushrooms: Wash ‘em gently (don’t drown ‘em). Pop the stems off and pat them dry — no soggy mushrooms here. Save the stems if you’re feeling thrifty, they’re good in stir fries or scrambled eggs.
- Make the filling: Mix the clams, green onion, garlic, garlic salt, oregano, and the melted butter in a bowl. Add a splash of clam juice to keep things moist, not wet. Stir in the egg, breadcrumbs, and all the cheese except the ¼ cup mozz (that’s for later). Taste it. It should be salty, cheesy, and a lil funky (in a good way).
- Stuff the mushrooms: Spoon the filling into each cap like you’re tucking them into bed. Don’t pack it down too hard — a nice lil mound is perfect. Place them in a greased baking dish, cuddled up close but not too crowded.
- Butter + bake: Pour ¼ cup melted butter evenly over everything. Cover the dish with foil and bake at 175°C (about 350°F) for 35–40 minutes. Your kitchen will smell insane. Like, garlic heaven insane.
- Final cheese bomb: Pull off the foil, sprinkle that last ¼ cup of mozzarella over the tops, and pop them back in for a few mins until it’s all melty and golden.
- Serve it up: If you’ve got fresh parsley, go for it. Otherwise, just eat them warm and melty, preferably standing over the stove while “taste testing” three in a row.

Tips for Success
- Use fresh mushrooms. Canned ones go mushy. You want bite, not sadness.
- Don’t overfill. Too much and they topple over mid-bake. Been there.
- Let the filling be moist, not wet. That clam juice is gold, but go slow.
- Grate your own cheese. Pre-shredded has weird anti-melt dust.
- Cover first, then finish uncovered. Keeps them juicy but still gets that cheesy top.
Storage and Reheating
- Fridge: Cool first. Store in an airtight container for up to 3 days.
- Reheat: Air fryer at 160°C for 4–5 mins is the move. Oven works too — 300°F until hot.
Microwave? Eh. Works, but loses the crisp. Still edible, just not its best self.
Frequently Asked Questions
- Can I use canned mushrooms?
Technically, yeah. But they’ll be super soft. Fresh is way better here. - What can I use instead of clams?
Chopped shrimp or even crab meat. Or skip seafood and go full cheese + herbs. - Do I have to use three kinds of cheese?
Nope. But the combo hits different. You can sub with just mozzarella + parm if that’s what you have. - Can I prep these ahead?
Totally. Stuff ‘em, cover, and keep in the fridge. Bake the next day. - Are they freezer-friendly?
Yes — bake first, then freeze. Reheat in the oven so they don’t go mushy.
Common Mistakes and How to Dodge Them
- Overstuffing the mushrooms: It looks cute at first, then they collapse mid-bake. Keep it neat — lil mound, not Mt. Everest.
- Too much clam juice: Makes it soggy and weird. Just a spoon or two, enough to bind. You can always add more. Can’t un-add.
- Not tasting the filling first: You’ve got raw cheese and seasoning in there. Give it a little taste before stuffing. Adjust salt or garlic if needed.
- Baking uncovered the whole time: They’ll dry out like a sad baguette. Cover first — then cheese it up and broil at the end.
- Using pre-shredded cheese only: They melt weird and clump. Get a block of mozz. Takes two minutes and makes a big diff.
