For meal prep, you can slightly undercook the omelets so the eggs remain tender after reheating, then store them in an airtight container in the refrigerator for up to 3 days. Reheat gently in a covered skillet over low heat or in the microwave at medium power in short bursts to avoid drying out the eggs. To change up the flavor while staying keto, try swapping the cheddar for pepper jack, adding a small handful of sautéed spinach or mushrooms, or finishing with a drizzle of olive oil for extra healthy fats. Always confirm that any salsa or seasonings you add are sugar-free to keep the net carbs low and keto friendly.
