Tips for the Best Tuna Noodle Casserole
Use Albacore Tuna

Shred Cheese Fresh
Freshly grated cheese melts more smoothly than pre-shredded varieties.
Season Gradually
Adjust salt after adding soup and cheese—they can already be salty.
Add Veggies
Frozen peas, chopped mushrooms, spinach, or broccoli make it healthier and heartier.
