Ingredients
Only a short list of simple ingredients is needed for this creamy slow cooker rice.
- 2 cups instant rice
- 16 oz baby bella mushrooms
- 2 cans beef broth (about 3 cups)
- 1 cup shredded Parmesan cheese
- 2 tbsp butter
- Salt and pepper to taste

Regular long-grain rice can replace instant if you increase the liquid slightly and extend the cook time. Chicken broth works in place of beef for a lighter flavor. Gruyère or a Parmesan-Romano blend can stand in for the shredded Parmesan. Freshly grated cheese melts more smoothly than pre-shredded.

Step-by-step instructions
These eight easy steps create a perfectly creamy rice dish with almost no effort.
Step 1: Prep the slow cooker
Lightly grease the inside of a 4- to 6-quart slow cooker or use a liner. This prevents sticking and makes cleanup effortless later.
Step 2: Add the rice

Pour the instant rice evenly across the bottom of the slow cooker. Spread it into a single level layer so it cooks uniformly.
Step 3: Layer the mushrooms
Slice the baby bella mushrooms and scatter them evenly over the rice. Do not stir; keep the layers distinct for best results.
Step 4: Pour in the broth
Open the cans of beef broth and pour them over the mushrooms and rice. The liquid should just cover the ingredients.
Step 5: Season lightly
Sprinkle a pinch of salt and black pepper over the top. Taste the broth first so you do not over-season the finished dish.
Step 6: Top with Parmesan
Scatter the shredded Parmesan evenly across the surface. It will melt into a golden, cheesy crust as the rice cooks.
Step 7: Cook on low
Cover the slow cooker and cook on low for 2 to 3 hours. Avoid lifting the lid so the steam stays trapped inside.
Step 8: Finish with butter
When the rice is creamy and the cheese is golden, add the butter on top. Let it melt for a minute, then gently stir and serve.
Tips & common mistakes
A few simple habits guarantee creamy rice instead of a dry or soggy result.
- Use instant rice for the correct texture and timing
- Do not stir during cooking or the rice turns mushy
- Keep the lid closed to maintain steady steam
- Add the butter only at the very end for richness
