Instructions

<dl><dt><strong>Boil the egg noodles and heat the oven:</strong></dt><dd>Preheat your oven to 375 degrees Fahrenheit and prepare a nine by thirteen inch baking dish by buttering it or spraying with nonstick spray. Bring a large pot of salted water to a rolling boil over mediumhigh heat. Add the egg noodles and cook them until just shy of al dente, about one or two minutes less than the package suggests. Drain the noodles well and toss them with a small drizzle of olive oil to keep them from sticking, then set aside while you prepare the sauce.</dd><dt><strong>Sauté the aromatics:</strong></dt><dd>In a large skillet or wide pot, melt the salted butter over medium heat. Add the finely diced onion and shallot and cook them gently until soft and translucent, about five minutes, stirring occasionally to prevent browning. Next, stir in the minced garlic and cook for just thirty seconds until fragrant but not browned to build the dish’s savory base flavor.</dd><dt><strong>Build the creamy sauce:</strong></dt><dd>Sprinkle the allpurpose flour over the softened vegetables and cook, stirring continuously, for one to two minutes to form a light roux. Slowly whisk in the chicken broth and half and half cream in stages, making sure to break up any flour lumps until you have a smooth sauce. Stir in the granulated vegetable bouillon, salt, freshly ground black pepper, dried thyme, and Dijon mustard. Let the mixture simmer while stirring frequently for five to seven minutes until it thickens into a creamy sauce.</dd><dt><strong>Finish the sauce with yogurt, tuna, peas, and cheese:</strong></dt><dd>Remove the pan from the heat and gently stir in the Greek yogurt until fully incorporated and smooth. Fold in the welldrained tuna flakes and frozen green peas, mixing carefully to combine. Finally, stir in one cup of shredded white cheddar cheese until it starts to melt into the sauce. Add the drained noodles and toss everything gently but thoroughly so the noodles are evenly coated with the rich sauce.</dd><dt><strong>Assemble the casserole and topping:</strong></dt><dd>Transfer the noodle mixture into the prepared baking dish spreading it into an even layer. In a small bowl, combine the remaining half cup of shredded cheddar cheese with the melted unsalted butter, tossing to coat evenly. Sprinkle this cheesy butter mixture over the top of the casserole to create a golden crust when baked.</dd><dt><strong>Bake until bubbly and serve:</strong></dt><dd>Place the casserole in the preheated oven and bake for twenty to twentyfive minutes, until the top is golden and bubbly along the edges. Let the casserole rest for about ten minutes after baking so the sauce thickens slightly and the noodles firm up for cleaner serving slices. Enjoy warm, ideally with a crisp green salad or steamed vegetables on the side.</dd></dl>

<p>My favorite ingredient in this casserole has to be the Greek yogurt because it adds a wonderful tang and creaminess that lifts the whole dish without overpowering the flavors. This casserole always reminds me of cozy family evenings when a warm, homemade dinner was all we needed to feel at home and cared for.</p>

Storage tips

<p>Store any leftovers covered tightly in an airtight container in the refrigerator for up to three days. Reheat gently in the oven or microwave until warmed through. This casserole can also be frozen well. Wrap it securely and freeze for up to three months, thawing overnight in the fridge before reheating to preserve the creamy texture.</p>

Ingredient substitutions

<p>If you don’t have half and half cream, whole milk with an extra tablespoon of butter added during the roux step works nicely for a lighter but still creamy sauce. Swap Greek yogurt with full fat sour cream for a tangier twist. For a crunchy topping alternative, crushed plain potato chips add a salty, playful texture instead of extra cheese and butter.</p>

Serving suggestions

<p>This casserole pairs beautifully with simple green salads or steamed seasonal vegetables like asparagus or broccoli. A crisp cucumber salad with dill or lemon also complements the rich, creamy flavors while adding a refreshing contrast.</p>

Common Questions About the Recipe

→ What type of noodles work best?

Egg noodles hold the sauce well and offer a tender bite. Slightly undercooking them helps retain texture after baking.

→ Can I use fresh tuna instead of canned?

Canned tuna provides convenient flakiness and moisture. Fresh tuna should be cooked separately and added cautiously to avoid drying out the dish.

→ How can I make the sauce creamier?

Incorporate full-fat dairy like Greek yogurt and half-and-half. Gently warm the sauce to prevent curdling for a velvety texture.

→ What are good substitute toppings?

Crushed potato chips add a crunchy, salty crust alternative to the classic cheddar and butter topping.

→ How to store leftovers properly?

Refrigerate in an airtight container up to 3 days. Reheat gently to maintain creaminess and avoid drying out the noodles.

→ Can I add vegetables to the dish?

Frozen peas are traditional, but additions like diced celery or mushrooms can enhance flavor and texture.

Steps to Follow

Step 01

Bring a large pot of salted water to a boil over medium-high heat. Cook the egg noodles until slightly under al dente, about 1 to 2 minutes less than package instructions. Drain well, toss with a drizzle of olive oil, and set aside.

Step 02

Preheat the oven to 375°F. Lightly butter or spray a 9x13 inch baking dish and set aside.

Step 03

Melt salted butter in a large skillet over medium heat. Add diced onion and shallot, cooking until soft and translucent, about 5 minutes. Stir in minced garlic and cook for 30 seconds until fragrant without browning.

Step 04

Sprinkle flour over the cooked aromatics, stirring constantly for 1 to 2 minutes to form a roux. Gradually whisk in chicken broth and half-and-half, breaking up any lumps. Add vegetable bouillon powder, salt, black pepper, dried thyme, and Dijon mustard.

Step 05

Allow the mixture to simmer while stirring frequently until slightly thickened and creamy, approximately 5 to 7 minutes.

Step 06

Remove from heat and stir in Greek yogurt until smooth. Gently fold in drained tuna and frozen peas. Mix in 1 cup shredded white cheddar until evenly combined and beginning to melt. Add drained noodles and toss to coat thoroughly.

Step 07

Transfer the noodle mixture evenly into the prepared baking dish. In a small bowl, combine remaining ½ cup shredded cheddar with melted unsalted butter. Sprinkle this mixture evenly over the top.

Step 08

Bake for 20 to 25 minutes until the topping is golden and the casserole bubbles around the edges. Allow to rest for 10 minutes before serving to let the sauce thicken and flavors meld.

Additional Notes

  1. Undercooking noodles slightly prevents mushiness after baking.
  2. Using tuna packed in olive oil enriches the flavor profile.
  3. Add Greek yogurt off heat to avoid curdling the sauce.
  4. Resting the casserole before serving enables cleaner slices and better sauce absorption.
