This protein-rich meal will fill you up and keep you full for hours afterward. 

Comforting and hearty, this sustainably sourced tuna noodle bake is the perfect weeknight dinner! This dish is very simple to make and only takes about 45 minutes from start to finish (and 25 of those is for baking!). Tuna is a great choice for a filling dinner—the protein in tuna will help keep you full for hours afterward and also provides a good source of healthy omega-3

Omega-3 fatty acids are considered essential fatty acids. Our body can’t make them—that’s why we need to eat them in delicious dishes like this tuna noodle casserole. Omega-3 fatty acids are found in fatty fish like tuna, salmon and halibut. They’re crucial for brain function and may reduce the risk of heart disease. 

The American Heart Association recommends eating fatty fish at least twice per week. Research shows that omega-3’s reduce inflammation and lower your risk of heart disease, cancer, and arthritis. Canned tuna is an easy way to get your recommended intake of omega-3. 

Ghee (or clarified butter) is used in this dish to impart a buttery, nutty flavor. Ghee is also rich in Vitamin A and D. I like to use bouillon chicken paste instead of cartons of chicken broth – you can keep the jar in the fridge for months and easily make chicken broth in seconds. Using egg noodles made with the whole yolk add extra protein and a rich golden color to the dish. To help lower the sodium load of the dish, coconut aminos are used in place of soy sauce. Coconut aminos add the familiar savory taste without the extra sodium.

Feel free to serve this casserole with a side salad tossed with vinaigrette for an extra serving of fiber and heart-healthy fats!
