Why: Seafood cooks quickly. In a slow cooker, it turns overcooked, rubbery, or falls apart.

❌ Not ideal for all-day cooking.

βœ… Better Option:

Add seafood in the last 15–30 minutes β€” just until opaque and tender.

🍀 Example: Add shrimp to chowder at the end.

❌ 8. Leafy Greens (Kale, Chard, Lettuce)

Why: Greens like kale can hold up okay, but most wilt into a sad, dark pile.

Lettuce? It melts.

βœ… Better Option:

Stir in leafy greens during the last 15–20 minutes.

🌿 Bonus: Brightens flavor and adds freshness.

❌ 9. Canned Soup (As a Base)

Why: Many canned soups already contain thickeners, starches, and seasonings.

In a slow cooker, they can become too thick, gloopy, or overly salty.

βœ… Better Option:

Use broth or stock as your base β€” then season fresh.

πŸ… If using canned soup (e.g., cream of mushroom), thin it with water and add late.

❌ 10. Alcohol (Wine, Beer, Liquor)

Why: Alcohol doesn’t fully evaporate in a slow cooker (due to lower temps).

It can leave a harsh, bitter taste and overpower the dish.

βœ… Better Option:

Deglaze with alcohol on the stove first, let it reduce, then transfer to slow cooker.

🍷 Or: Add small amounts near the end β€” 30 mins before serving.

❌ 11. Frozen Meats or Veggies
