A delightful and hearty frittata combining savory sausage, fresh greens, and creamy cheese for a perfect meal.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated to maintain even cooking.
In a skillet, cook the sausage over medium heat until browned. Drain any excess fat.
Break the sausage into small pieces for even distribution in the frittata.
Sauté the mushrooms and garlic in butter until tender and the liquid has evaporated.
Adding a splash of white wine can enhance the flavor.
Spread the cooked sausage evenly in the bottom of a greased baking dish.
Use a spatula to spread the sausage evenly for consistent layers.
Layer the sautéed mushrooms over the sausage, followed by the spinach and cheese.
Press down gently to compact the layers slightly.
In a mixing bowl, whisk together the eggs, milk, and mustard until well combined.
Whisking thoroughly incorporates air, making the frittata fluffier.
Pour the egg mixture evenly over the layered ingredients in the baking dish.
Pour slowly to ensure even coverage.
Bake in the preheated oven for 45-50 minutes, or until the center is set.
Check doneness by inserting a knife into the center; it should come out clean.
Let the frittata cool for 10 minutes before slicing and serving.
Cooling helps the frittata set, making it easier to slice.
