Step-by-Step Instructions
Step 1: Prepare the Noodles
Cook the whole wheat egg noodles according to package directions until al dente. Drain and set aside.

Expert Tips for the Best Skinny Tuna Casserole
Choose the Right Tuna: Opt for chunk light tuna packed in water for the leanest option. Albacore tuna has slightly more fat but can also work.
Don’t Overcook the Noodles: Cook noodles al dente since they’ll continue cooking in the oven. This prevents them from becoming mushy.
Customize Your Veggies: Add mushrooms, carrots, or broccoli for extra nutrition and flavor variety.
Make It Creamier: If you prefer an even creamier texture, add 1/4 cup of low-fat cream cheese to the sauce mixture.
Storage and Reheating: This casserole stores beautifully for up to 3 days in the refrigerator. Reheat portions in the microwave or oven until warmed through.
