Instructions

Bring a medium pot of salted water to a boil. Prepare an ice bath. Blanch green beans for 2–3 minutes until bright green, then transfer to ice water. Drain and pulse in a food processor 4–5 times until coarsely chopped. Transfer to a large bowl.
Pulse mushrooms in the food processor until finely chopped, stopping before they become a paste.
In a skillet, melt 2 Tbsp butter over medium heat. Add sliced onion, season with salt, and cook 15 minutes until softened and lightly caramelized. Add garlic and cook 1 minute. Stir in mushrooms and cook 10 minutes until browned. Transfer to the bowl with green beans.
In the same skillet, melt remaining 3 Tbsp butter. Whisk in flour and cook 1 minute. Slowly add milk, whisking until thickened and bubbling, about 5 minutes. Season with salt and pepper. Add to the bowl with veggies, cover, and chill 20 minutes.
Preheat oven to 375°F (190°C). Grease two 24-cup mini muffin tins.
On a floured surface, unroll one can of crescent dough, pinch seams into a rectangle, and roll to 15″×12″. Cut into 24 squares and press into muffin cups. Repeat with second can.
Bake dough cups 5 minutes until lightly puffed. Fill each with 1 Tbsp chilled mixture and top with crispy onions.
Bake 8 more minutes until warmed through and onions darken slightly. Serve warm.

Notes

Add a pinch of cayenne or smoked paprika for heat.

Mix some fried onions into the filling for extra crunch.

Stir in grated Parmesan for deeper savory flavor.

Use puff pastry instead of crescent dough for a flakier bite.
