For the most keto-friendly result, choose a full-fat sausage with no added sugar, fillers, or starches and always check the nutrition label for hidden carbs. The onion is optional and used in a small amount to keep net carbs low while still adding flavor, so omit it if you need to lower carbs even further. This stir fry reheats well in a skillet over medium heat and can be stored in an airtight container in the refrigerator for up to three days, making it ideal for meal prep. If you prefer a slightly richer dish, stir in an extra tablespoon of olive oil or a small knob of butter at the end of cooking to boost healthy fats and flavor.
