  • 16 ounces egg noodles, cooked to al dente
  • ¼ cup salted butter
  • 1 cup cremini mushrooms, finely chopped, about 4 ounces
  • ¼ cup unbleached all purpose flour
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon parsley
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 4 cups milk
  • 2 cups shredded co-jack cheese
  • 1 cup frozen peas
  • 10 ounces canned tuna, drained, 2 cans
  • 1 cup crushed saltine crackers


  • Preheat oven to 375°F and lightly grease a 9x13 deep sided casserole dish.
  • Cook the egg noodles to one minute less than the al dente directions on the package. Drain and drizzle with a little olive oil so they don't stick together.
  • While the noodles cook make the sauce. In a large, deep sided skillet melt the butter over medium-low heat. Add the chopped mushrooms and cook until the mushrooms are deep brown in color and soft, about 6-7 minutes.
  • Increase heat to medium and stir in the all purpose flour, garlic powder, onion powder, parsley, salt, and black pepper. Cook for 1-2 minutes.
  • Slowly stir in the milk while whisking. Bring sauce to a boil, then reduce heat to low and simmer for 5-7 minutes until sauce has thickened and coats the back of a spoon.
  • Stir in half of the shredded cheese until fully melted.
  • Then, stir in the drained canned tuna and frozen peas.
  • Add the cooked and drained pasta and stir so everything is evenly incorporated.
  • Spread the casserole mix into the casserole dish and spread it out evenly.
  • Sprinkle the top of the casserole with the remaining shredded cheese followed by the crushed saltine crackers.
  • Bake uncovered for 20 minutes until heated through and crackers are golden brown.
