Add bacon to a bacon sheet and bake for 15 minutes. When done, use tongs to place on paper towel to absorb excess grease. Set aside.
Sausage Patties:
While bacon is cooking, add sausage patties to a skillet over medium high heat on the stove. Cook approx 3-4 minutes on one side, then flip and cook for an additional 3-4 minutes, or until sausage is fully cooked.
Sheet Pan Eggs:
In a large bowl, add eggs, milk and generously season with salt and pepper. Using a mixer, beat the eggs together.
Open oven and pull out oven rack. Place empty baking sheet on rack, then pour egg mixture on it (doing it this way helps to prevent spilling the eggs). Gently push the rack back in and bake for 30 minutes, or until edges begin to golden and the center is cooked.
Let eggs cool then slice into 12 servings for each breakfast sandwich. These can be square or circle shaped by using the rim of a glass as a "cookie cutter shape".
Assembling Breakfast Muffins:
Separate each english muffin in half, and place in rows on the counter. Spread butter on to each side of the egg muffin.
Add the egg shapes to the bottom of each muffin.
Top six of the english muffins with sausage patties, and six with pieces of bacon.
Add cheese slices to each one. Put tops of english muffins back on.
Freezing Instructions:
Wrap each muffin in parchment paper or plastic wrap. Label the top with breakfast muffin flavor (sausage or bacon). Add all sandwiches to a freezer bag. Remove as much air as possible, then seal tightly. These can be kept in the freezer for up to 3 months.
Reheating Instructions:
Oven Instructions From Frozen: Preheat oven to 350°F. Remove parchment paper and place breakfast sandwiches on a baking sheet. Bake for 30-40 minutes, or until fully heated through and cheese has melted.
Oven Instructions When Thawed: Remove sandwiches from freezer and let them thaw overnight in the fridge (still wrapped in parchment paper). Preheat oven to 350°F. Remove parchment paper and place breakfast sandwiches on a baking sheet. Bake for 5-8 minutes, or until fully heated through and cheese has melted.
Microwave Instructions: Thaw overnight in the fridge. Remove from parchment paper and wrap in a paper towel. Microwave for 40 seconds on defrost. Flip over and microwave on high for 20 seconds, or until cheese has melted and it's heated throughout.
Recipe Notes:
These sandwiches taste great with extra sauce! Add your favorites: hot sauce, salsa, guacamole, and hummus, etc.
Add sweet potatoes and spinach to the sheet pan eggs before cooking for a healthier breakfast sandwich - see recipe.
