As you know, I love paging through cookbooksโespecially vintage ones. (And as I write this, Iโm realizing vintage and antique are probably two different things. Vintage might mean the 1970s. Antique? Likely the 1950s or earlier.)

I especially love digging through my grandmotherโs recipe box to see what she was making when she entertained. Time and again, I come across recipes that were clearly loved by allโฆ but maybe not loved by all tummies.
This recipe is one of thoseโand thatโs exactly why I gave it a modern update.
๐ฅ Why This Version Works So Well
Mushroom tarts are a classic bite-size appetizer we donโt see very often anymoreโbut when they appear, theyโre always a hit. Traditionally, theyโre made with phyllo dough or puff pastry. Delicious, yesโbut sometimes heavy, fiddly, or not ideal for everyone.
Here, Iโve swapped the pastry for thinly sliced yellow potatoes. The result?
- No dough to fuss with
- Added nutrients
- Naturally gluten-free
- And I promiseโyou wonโt miss the pastry at all
These are the kind of appetizers that disappear immediately once they hit the table.
โจ Make Them Your Own
If youโre feeling adventurous, this recipe is wonderfully flexible:
- Use any typeโor combinationโof mushrooms
- Swap in dill Havarti for a whole new flavor profile
- Prefer not to cook with wine? Vegetable broth works beautifully
I also love serving these as a salad or first course alongside mixed greens dressed simply with light olive oil and red wine vinegar. When I do, I plan on 3โ4 tarts per person.
๐ Mushroom Tarts with Potato Shells
Makes 24
Ingredients:
Olive oil
1 lb fresh button mushrooms
1 medium onion
ยฝ cup parsley
ยฝ cup dry white wine (such as Sauvignon Blanc)
1 dash hot pepper sauce
โ
tsp salt
โ
tsp pepper
2 medium yellow potatoes (about 2 inches in diameter)
4 oz Havarti or Monterey Jack cheese
Instructions:
- Heat the oven to 400ยฐF. Lightly oil the wells of a mini muffin pan and set aside.
- Finely chop the mushrooms, onion, and parsley.
- In a large skillet, combine the mushrooms, onion, parsley, wine, and hot pepper sauce. Cover and cook 5โ7 minutes, stirring occasionally, until mushrooms are tender.
- Uncover and cook until liquid evaporates. Season with salt and pepper. Set aside to cool.
- Thinly slice the potatoes (โ -inch thick) using a mandoline.
- Pat slices dry and place in a single layer on a microwave-safe plate. Cover with a damp paper towel and microwave on HIGH for 1 minute, until pliable.
- Gently press each potato slice into the wells of the muffin pan.
- Add about 2 teaspoons of mushroom mixture to each cup.
- Cut cheese into ยฝ-inch cubes and place one on top of each tart.
- Bake 15โ18 minutes, until lightly browned. Serve warm.
Make it Easy on yourself with these shortcuts:
๐น Easy
- Use pre-sliced mushrooms instead of whole to skip chopping.
- Swap fresh parsley for dried parsley (about 2 Tbsp) to save prep time.
- Shred the cheese instead of cubingโsame flavor, faster topping.
๐น Easier
- Replace fresh mushrooms and onions with a store-bought sautรฉed mushroom blend or frozen mushroom/onion mixโjust cook off excess liquid.
- Use pre-shredded cheese to skip cutting and cleanup.
- Microwave the potatoes all at once using a mandoline + stacking trick between paper towels.
๐น Easiest
- Skip the potato shells and use frozen mini phyllo shells or refrigerated biscuit dough pressed into the pan.
- Use jarred mushroom tapenade or mushroom bruschetta as the fillingโno cooking required.
- Bake, melt cheese, and serve. Done. ๐
