Begin by crisping the phyllo cups in the oven according to package instructions.
In a skillet, cook the bacon over medium heat until crisp. Remove the bacon from the skillet and put it on a paper towel-lined plate. Add the mushrooms and onion to the pan. Cook for 3 or 4 minutes until soft.
Add the chicken broth and cook for another 4-6 minutes. Add the crabmeat and the cream cheese, stir until the cream cheese melts. Stir in the spinach until wilted and all is combined.
Stir in the Parmesan cheese and the lemon juice and remove the skillet from the heat. Scoop rounded teaspoons of crab filling into the crisp phyllo cups. Top each cup with bacon crumbs and chopped parsley. Serve immediately. Recipe makes 30 phyllo cups.
