What Makes This Tuna Noodle Casserole So Good?

Egg Noodles – These wide, tender noodles soak up all the creamy goodness, making every bite comforting and satisfying.
Avocado Oil – Adds a subtle richness and helps sauté the onions and garlic to perfection.
Sweet Onion & Garlic – A dynamic duo that builds a flavorful base, bringing depth and a touch of sweetness.
All-Purpose Flour – The secret to a velvety, thick sauce that clings to every noodle.
Onion Powder & Garlic Powder – Extra layers of flavor to enhance the savory goodness.
Salt & Black Pepper – Essential seasonings to balance and highlight all the flavors.
Chicken Broth – A flavorful liquid base that makes the sauce rich without being too heavy.
Half and Half – Adds the perfect amount of creaminess for a luscious, comforting texture.
Peas & Carrots – A pop of color and a touch of natural sweetness to round out the dish.
Chunk White Albacore Tuna – Mild, flaky, and packed with protein, it’s the star of the show!
Asiago Cheese – Bold, nutty, and melts beautifully into the sauce for an irresistible cheesy finish.
Fresh Parsley (Optional) – A sprinkle of freshness that adds a little brightness to every bite.

Directions

Bring a large pot of water to boil and cook the egg noodles according to package directions until al dente. Drain and transfer the pasta to a bowl. Set aside.
In the same pot, reduce the heat to medium and add the avocado oil.
Saute the onions for 3-5 minutes until it begins to soften and become translucent. Then add the minced garlic and saute for another 1 minute, until fragrant.
Sprinkle on the all-purpose flour and seasonings, then stir together. Continue to stir and cook for 2–3 minutes.

Slowly pour in the chicken broth and stir continuously until well incorporated and there are no clumps of flour.

Add in the cooked noodles, thawed veggies, and tuna. Mix to combine and let cook for 5 minutes.

Remove from the heat and stir in the freshly grated cheese.

Tips for the Best Tuna Noodles

Cook Noodles Al Dente: Slightly undercook your noodles (al dente) since they’ll absorb some of the sauce while baking. This keeps them from getting mushy. [For me, that meant cooking them 6 minutes instead of the 8-10 directed on the package.]
Freshly Grate Your Cheese: Skip the pre-shredded cheese! Freshly grated Asiago or Parmesan melts smoother and tastes better since it doesn’t have added anti-caking agents.
Customize Your Veggies: Don’t love peas and carrots? Swap them for your favorite frozen mix, like green beans and corn, or just stick with peas.
Use High-Quality Tuna: Choose chunk white albacore tuna for the best flavor and texture. It holds up well and adds a richer taste.
Thicken the Sauce Just Right: Let the sauce cook until it’s thick and creamy—like gravy—before adding the noodles and other ingredients. If it seems too thin, simmer it a bit longer.
Add Crunch (Optional): For a classic casserole topping, sprinkle some crushed Ritz crackers or breadcrumbs mixed with melted butter.

Notes

This dish is great for meal prep! Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven until warmed through.
Don’t have half and half? Substitute with equal parts whole milk and heavy cream for a similar result.
Make it your own! Swap Asiago for cheddar, mozzarella, or even a blend of cheeses for different flavor profiles.
