Recipe Tips
- Do I need to soak the lima beans? No soaking is required, but make sure to rinse them well before using.
- Can I use white rice instead of brown? Brown rice holds up better in long cooking times, but white rice can be used if added later in the cooking process.
- How to add more protein: Stir in cooked lentils or plant-based sausage near the end of cooking.
- Can I cook this on low? Yes, but it may take closer to 10–11 hours for the beans to fully soften.
- Can I sauté the onions first? Yes, sautéing the onions in a bit of broth adds extra depth of flavor.
