Cook the base ingredients (broth, vegetables, aromatics) first.
Add fish or shrimp in the last 20–30 minutes to ensure tenderness.
3. Pasta and Rice (Uncooked)
Throwing uncooked pasta or rice into a slow cooker can lead to overcooked, mushy grains or uneven cooking. Additionally, rice left too long at low temperatures can develop a bacterial risk (Bacillus cereus).
Tip:
Cook pasta separately and add it at the end, or slightly undercook it to finish in the slow cooker.
For rice-based dishes, pre-cook rice or use a quick-cooking variety and combine near the end of cooking.
4. Potatoes (Certain Varieties)
While starchy potatoes like Russets tend to disintegrate over long cooking times, waxy potatoes (like Yukon Gold or Red) hold up slightly better but may still become soft and mealy.
Tip:
Cut potatoes larger than usual to withstand hours of simmering.
Consider adding them halfway through cooking rather than at the start.
5. Leafy Greens (Spinach, Kale, Lettuce)
Leafy greens break down quickly, turning into a slimy, unappealing mush after long hours in a crockpot.
Tip:
Add delicate greens in the last 15–30 minutes of cooking.
For sturdier greens like collard or chard, chop them larger and add earlier, but monitor texture.
6. Fresh Herbs (Basil, Parsley, Cilantro)
Fresh herbs lose their flavor and vibrancy over long cooking times. They can turn dull, bitter, or disintegrate entirely.
