Step 1

Preheat oven to 400 degrees. Heat your pan (my absolute fave!) on medium heat on stovetop. Add 2 T of the butter to the pan. After butter melts, add onion, sausage and broccoli, and cook for 5-7 minutes. Then add 1 T more of butter and mushrooms to pan. Cook mushrooms for ~ 3 mins.

Step 2

While pan ingredients are cooking, whisk together eggs, milk, cheese, and salt/pepper in a bowl. Pour egg mixture into pan and spread evenly over the ingredients. Cook on stovetop for 3 minutes (no stirring!) until edges start to set.

Step 3

Carefully place pan in oven and cook for 10 minutes. The sausage frittata is done when eggs appear set and frittata is separating a bit from the edges of the pan. Let cool a bit, slice, and serve!
