Ingredients

Tuna Casserole

8 ounces egg noodles
4 tablespoons unsalted butter
1 medium yellow onion finely diced
1 rib celery chopped
2 cloves garlic minced
3 tablespoons flour
2 cups whole or 2% milk
½ teaspoon kosher
½ teaspoon freshly ground black pepper
1 cup shredded sharp cheddar
1 cup shredded white cheddar
½ cup sour cream
2 (5-ounce) cans solid white albacore tuna in water, drained
1 cup frozen peas

Cracker Topping

1 ½ cups crushed Ritz crackers
3 tablespoons unsalted butter melted
Chopped dill or chives

Instructions

Preheat oven to 400 degrees. Grease or coat a 9 x 9-inch casserole dish with nonstick cooking spray.
Cook noodles al dente according to package instructions; drain well.
In a skillet or pan, melt the butter over medium heat. Add the onions and celery and cook until tender, about 7 minutes, stirring several times.
Reduce the heat to low and add the garlic, cooking for 1 minute while stirring constantly. Sprinkle the flour over the vegetables and cook for 2 minutes while stirring.
Slowly stir in the milk until smooth and combined. Simmer for about 5 minutes or until slightly thickened. Season with salt and pepper to taste.
Remove from the heat and stir in the shredded cheese and sour cream. Stir in the drained tuna, frozen peas, and cooked noodles. Spoon the contents into the prepared baking dish.
In a small bowl, combine the crushed Ritz Crackers and butter. Sprinkle the mixture over the casserole dish.
Bake for 15-20 minutes or until the casserole is heated through and lightly browned on the top. Sprinkle with chopped fresh dill or chives.

Notes

Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat in the microwave at reduced power or in a skillet over low heat. The cracker topping will not be as crunchy, but it will still be delicious.
If freezing leftovers, spoon the cooled contents into a sturdy freezer-safe container. Thaw in the fridge overnight and reheat in the microwave at reduced power or in the oven at 350 degrees in a casserole dish.
