• Cook: Low 4–5 hours or High 2.5–3 hours until broccoli is fork‑tender.

• Gluten‑free: use GF‑certified broth; cornstarch thickens without flour.

• Lighter: use evaporated milk in place of half‑and‑half.  
• Extra veg: swap in some cauliflower.  
• Heat: add a pinch of cayenne or diced jalapeño.

• Crusty sourdough or garlic bread  
• Classic grilled cheese  
• Baked potatoes or potato skins  
• Roasted veggies (cauliflower, carrots, Brussels sprouts)  
• Simple green salad with vinaigrette
