Oven-baked omelette with sausage and cheese

Ingredients:

• Butter, for greasing the pan
• 2 tbsp. l. olive oil
• 1 small onion, diced
• 220 g mild turkey sausage, casing removed
• 8 large eggs
• 1/3 cup whole milk
• 1 teaspoon coarse salt
• 1 red bell pepper, diced
• 120 gr. grated Gruyère cheese
• 1/4 tbsp. + 2 tbsp. l. chopped parsley

Preparation:

1. Preheat oven to 220°C. Lightly grease a 20 x 20 cm baking pan with butter.
2. Heat olive oil in a medium skillet over medium-high heat. Add the onion and cook until translucent, about 3 minutes. Add the sausage and cook until darkened, about 5 minutes. Set the skillet aside to cool.
3. In a large bowl, whisk together the eggs, milk, salt, and pepper to taste until smooth, about 20 seconds. Add the red pepper flakes, 1 cup Gruyère cheese, and 1/4 cup parsley. Stir in the onion and ground beef mixture. Pour the egg mixture into the prepared pan. Sprinkle with the remaining cheese. Bake for 20-25 minutes or until golden brown.
4. Before serving, cut the baked omelette into wedges and sprinkle with the remaining parsley.
