In a medium saucepan, bring water or chicken broth to a boil.
- Gradually whisk in the polenta, stirring constantly to prevent lumps.
- Reduce the heat to low and continue to cook, stirring frequently, until the polenta is thick and creamy, about 20-30 minutes.
- Remove from heat and stir in butter and Parmesan cheese until well combined.
- Season with salt to taste.
- Serve the polenta warm as a creamy base for your steak.
