First, I use a microwave-safe container that's big enough to give my Carbonara space. This way, it heats evenly.
To avoid a saucy mess in my microwave, I gently cover the container with a microwave-safe lid or plate. I don't seal it entirely; I leave a small gap for steam to escape.
Here's the key—I don't blast my Carbonara on high power. Instead, I set my microwave to 50% power or lower. It takes a bit longer, but my sauce stays creamy and luscious. Start with 1 minute at 50% power, then continue stirring in between in 30-second increments if needed.
About halfway through the reheating time, I carefully remove the container from the microwave (it might be hot!) and gently stir in the Carbonara. This helps distribute the heat evenly and keeps the sauce from clumping.
Once the time is up, I always check the temperature and consistency of my Carbonara. If it's not quite ready, I pop it back in the microwave for a few more seconds, keeping a close eye on it.
