Preheat your oven to 375 degrees Fahrenheit.
This ensures your Cornish hens cook evenly.
In a bowl, mix cream cheese, chopped spinach, diced mushrooms, garlic powder, onion powder, salt, and pepper.
This will be your stuffing mixture.
Carefully stuff each Cornish hen with the cream cheese mixture.
Rub olive oil over the hens and sprinkle paprika, salt, and pepper evenly on top.
This adds flavor and helps them brown beautifully.
Place the stuffed hens on a baking sheet and bake for 1 hour, or until they reach an internal temperature of 165°F.
Rotate them halfway through for even cooking.
