Preheat your oven to 400°F and line a 12-cup muffin tin with parchment liners or spray with cooking spray.
Brown the sausage in a skillet over medium-high heat for 8-10 minutes, breaking it apart with a wooden spoon.
In a large bowl, whisk together eggs, heavy cream, salt, and pepper until well combined.
Divide the cooked sausage between the muffin cups (about 3 tablespoons each).
Sprinkle cheese on top of the sausage (1 tablespoon per cup).
Pour the egg mixture evenly into each muffin cup.
Bake for 15-20 minutes until eggs are set.
