1. Cook the ground breakfast sausage in a large skillet over medium heat, breaking it into small crumbles, until browned and fully cooked. Transfer to a paper-towel-lined plate to drain and cool slightly.
2. Preheat the oven to 350°F. Place the silicone mold on a baking sheet for stability and lightly brush each cavity with olive oil to prevent sticking.
3. Evenly distribute the cooked ground sausage among the 12 silicone cups. Crack one whole egg on top of the sausage in each cup. Gently poke each yolk with a fork and swirl slightly to create a marbled egg mixture. Season with salt and garlic powder.
4. Bake for 18–22 minutes, or until the baked eggs are set. Transfer the cooked rounds to a paper-towel-lined plate to absorb any excess grease.
5. Arrange the split English muffins cut-side up on a baking sheet lined with parchment paper. Place under the broiler for 1–2 minutes, just until golden brown. Watch closely, then cool completely before assembling.
6. Place one round of egg and sausage on the bottom of each English muffin. Add a cheese slice and close with the top half of the muffin.
7. Wrap each sandwich tightly in parchment paper or aluminum foil, depending on how you plan to reheat. Use parchment paper if you’ll reheat in the microwave, it’s safe for direct heating and easy to unwrap. Use aluminum foil if you plan to reheat in the air fryer, oven, or toaster oven for a crisp exterior.
8. Place wrapped sandwiches inside a labeled freezer bag or airtight container. Store in the freezer for up to 3–6 months for best results.

How to Reheat Freezer Breakfast Sandwiches

• Microwave: Remove the sandwich from the freezer and keep it wrapped in parchment paper. Heat on 50% power for 60–90 seconds, then at full power for another 30–45 seconds, or until heated through and the cheese has melted.
• Air Fryer: Unwrap the sandwich and place it directly in the basket. Heat at 350°F for 8–10 minutes, flipping halfway through, until warmed through and lightly crisp on the outside.
• Oven: Preheat the oven to 375°F. Place sandwiches (still wrapped in aluminum foil) directly on the rack or a baking sheet. Bake for 20–25 minutes, or until hot in the center and the cheese is melted.
• Toaster Oven: Place the sandwich (still wrapped in aluminum foil) on the rack or a small tray. Heat at 350°F for 10–12 minutes, or until the center is hot and the cheese slice is melted. For extra crispness, unwrap for the last 2 minutes of heating.
