Tuna Noodle Skillet Casserole

This tuna noodle skillet casserole is basically comfort food’s greatest hits album all rolled into one cast iron skillet masterpiece.

Picture this: tender egg noodles swimming in a creamy, savory sauce that’s been infused with aromatic garlic and onions, while colorful carrots and peas add that perfect pop of sweetness and crunch.

The beauty of this recipe lies in its brilliant simplicity – everything cooks together in one skillet, which means less cleanup and more time to enjoy that first glorious bite.

What makes this version absolutely irresistible is the way the cream of mushroom soup creates this velvety base that clings to every single noodle, while the melted marbled cheddar cheese adds that gooey, indulgent factor we all secretly crave.

The final flourish of crushed garlic croutons on top delivers that satisfying textural contrast – imagine the crunch giving way to all that creamy, cheesy goodness underneath.

This is the kind of recipe that transforms a regular Tuesday night into something special, proving that the best comfort food doesn’t need to be complicated to be absolutely soul-satisfying.

Ingredients

For the Base:

1 tablespoon olive oil (extra virgin recommended for best flavor)
1 cup diced onion (about 1 medium yellow onion)
1 teaspoon minced garlic (fresh or quality jarred)

For the Sauce and Noodles:

4 cups chicken broth (or water, though broth adds significantly more flavor)
8 ounces egg noodles (approximately 4 cups dry)
10-ounce can cream of mushroom soup (condensed)
2 cups frozen carrots and peas (mixed vegetable blend)
Salt and pepper to taste

For the Protein and Toppings:

12-ounce can white tuna in water, drained (albacore preferred for texture)
1 cup marbled cheddar cheese, freshly shredded
1 cup garlic croutons, crushed (store-bought or homemade)

Instructions

Prepare the Aromatic Base:

Heat a large cast iron skillet or heavy-bottomed pan over medium heat and add the 1 tablespoon olive oil. The oil should shimmer slightly but not smoke – this indicates the perfect temperature for sautéing without burning the aromatics.
Add the 1 cup diced onion and 1 teaspoon minced garlic to the heated oil. Sauté until the onions become tender and translucent, approximately 3 minutes. You’ll know they’re ready when the onions have softened and the garlic becomes fragrant without browning.

Build the Creamy Sauce:

Add the 4 cups chicken broth and 10-ounce can cream of mushroom soup to the skillet. Using a whisk, blend the mixture until completely combined and smooth – this step is crucial for preventing lumpy sauce. The mixture should have a uniform, creamy appearance.
Stir in the 8 ounces egg noodles and 2 cups frozen carrots and peas. Season generously with salt and pepper to taste, keeping in mind that the flavors will concentrate as the liquid reduces. Bring the entire mixture to a gentle boil, then immediately reduce heat to maintain a steady simmer.

Cook to Perfection:

Simmer the mixture uncovered, stirring occasionally to prevent sticking, until the noodles are tender and the sauce has reduced to a creamy consistency, approximately 20 minutes. The noodles should be al dente and the sauce should coat them beautifully without being too thin or too thick.

Add Protein and Cheese:

Using a fork, flake the 12 ounces drained tuna into bite-sized pieces, then gently fold it into the pasta mixture. Be careful not to overmix, as you want to maintain some texture in the tuna pieces.
Sprinkle the 1 cup shredded marbled cheddar cheese evenly over the top of the pasta. Cover the skillet and simmer until the cheese melts completely and the tuna is heated through, approximately 3-5 minutes.

Finish and Serve:

Remove from heat and sprinkle the 1 cup crushed garlic croutons over the entire surface for that perfect textural contrast. Serve immediately while hot and bubbly for the ultimate comfort food experience.

Recommended Equipment and Kitchen Tools

Essential Tools (for best results):

Cast iron skillet (12-inch recommended) – provides even heat distribution and goes beautifully from stovetop to table for serving

Fork – ideal for flaking the tuna to the perfect texture

Helpful Upgrades:

Pro Tips and Troubleshooting

Professional Techniques:
Don’t skip the sautéing step – building that aromatic base with properly cooked onions and garlic creates the flavor foundation. Whisk the soup thoroughly with the broth to prevent lumps that won’t dissolve during cooking. Drain tuna completely by pressing it in the strainer to remove excess water that could make the dish watery.

Common Mistake Prevention:
Avoid overcooking the noodles – they’ll continue cooking in the hot sauce even after removing from heat. Don’t add cheese too early or it may become stringy instead of creamy. Stir gently when folding in the tuna to maintain texture rather than creating a mushy mixture.

Storage and Reheating:
Store leftovers in the refrigerator for up to 3 days in airtight containers. Reheat gently on stovetop with a splash of broth to restore creaminess, or microwave in 30-second intervals, stirring between. Avoid freezing as the dairy-based sauce may separate when thawed.

Make-Ahead Strategy:
Prepare through step 5, then cool and refrigerate. When ready to serve, reheat gently, add tuna and cheese, then finish with croutons. The croutons should always be added fresh to maintain their crunch.

Scaling Tips:
This recipe doubles easily for larger crowds – just use a larger skillet or Dutch oven and increase cooking time slightly for the liquid to reduce properly.

This tuna noodle skillet casserole proves that the best comfort food doesn’t require complicated techniques or exotic ingredients – just quality basics combined with a little know-how and a lot of love. Every forkful delivers that perfect balance of creamy, cheesy satisfaction with just enough textural interest to keep things exciting, making it the kind of recipe that earns a permanent spot in your weekly rotation.
