Preheat the oven to 375ºF (190ºC). Heat a 10-inch (26 cm) oven-safe skillet over medium-high heat.
Remove the casing from the chorizo and crumble it into the skillet. Cook for 5 to 7 minutes, stirring occasionally, until fully cooked and crumbled. Remove the chorizo from the pan and set aside.
Add the olive oil to the skillet. Once hot, add the diced onion and minced garlic. Cook for about 5 minutes or until the onion has softened.
Add the sliced mushrooms and cook for 10 minutes or until golden brown. Stir in the cooked chorizo and remove the skillet from heat.
Whisk together the eggs, cream, and chopped spinach in a large bowl until well combined. Pour the egg mixture into the skillet, stirring to combine all the ingredients evenly.
Sprinkle the top with grated Parmigiano Reggiano. Transfer the skillet to the oven and bake for 15 to 18 minutes or until the eggs are fully set.
Remove from the oven, let cool slightly, and cut into 8 equal pieces. Serve and enjoy!
