Ingredients

  • 8 ounces medium shell pasta cooked al dente according to package directions
  • 4 tablespoons butter divided
  • 1 medium stalk celery thinly sliced or diced
  • ¼ cup diced onion
  • 8 ounces mushrooms sliced or diced
  • olive oil as needed
  • 4 tbs flour
  • 1 14.5 ounce can chicken broth just under 2 cups, warmed
  • 1 cup milk warmed
  • ¼ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • ⅛ teaspoon dill
  • 2 tsp fresh lemon juice more if desired (I desire)
  • 2 tablespoons fresh minced parsley
  • 1 cup freshly grated Parmesan cheese divided
  • 5 oz can tuna packed in water, more if desired
  • Topping:
  • ¼ cup Ritz cracker crumbs mixed with about 1/2 tablespoon melted butter
  • or ¼-½ cup broken up potato chips I recommend kettle style

Instructions

  • Melt 1 tablespoon butter in a large skillet. Add celery and saute for 2-3 minutes. Add onion and cook 2-3 minutes longer, stirring often. Add mushrooms and cook 3-5 more minutes, until mushrooms are golden and tender. If needed for moisture, add a drizzle of olive oil to the pan after the mushrooms are added; more if needed during remaining cooking time. Remove vegetables from pan and set aside.
  • Melt remaining 3 tablespoons butter in pan and add flour. Stir constantly for 30 seconds. Slowly add broth and milk, a little at a time while constantly whisking until mixture is smooth. Bring to a low simmer. Add salt, pepper, and dill. Stir constantly until thickened and bubbly, 2-3 minutes. Reduce heat to low and add lemon juice, parsley, and 1/2 cup Parmesan cheese. Whisk until smooth and taste. Season with additional salt and pepper to taste, and extra lemon juice if desired.
  • Remove from heat and add pasta, vegetables, and tuna. Stir to combine and place in a 3 quart baking dish. Sprinkle with remaining ½ cup cheese (feel free to add more if you want) and sprinkle cracker crumbs or chips on top.
  • Bake at 350℉ for 25-30 minutes, until top is golden and pasta is hot and bubbly. Let rest 10-15 minutes before serving to allow sauce to thicken.
