Instructions

• Preheat the oven to 375°F.
• Line a baking sheet with parchment and place the bacon on it.
• Cook the bacon until crisp, about 15 to 20 minutes.
• While the bacon cooks, cook the sausage, breaking it up with a spatula.
• Remove the cooked sausage, then cook the onion and spinach until the onion is tender.
• Cool the bacon and crumble it.
• Reduce the oven temperature to 350°F.
• Whisk the eggs with the milk, salt, and pepper in a large bowl.
• Grease a muffin tin and divide the sausage, spinach, onion, egg mixture, and most of the bacon among the cups.
• Bake for 20 to 25 minutes, until the centers are set and no longer runny.
• Top some cups with the reserved bacon and cheddar.
• Return the tin to the oven briefly, just until the cheese melts.
• Remove from the oven, cool briefly, and serve.
