  • 7 oz. can tuna, drained and flaked
  • 1/2 cup chopped green onion
  • 1/2 teaspoon salt
  • 1/8 teaspoon pepper
  • 2/3 cup evaporated milk
  • 10 3/4 oz. can cream of mushroom soup
  • 1 cup shredded American cheese
  • 3 cups cooked elbow macaroni
  • 2 oz. jar chopped pimiento
  • 1/2 cup water
  • hard-cooked egg slices (optional)

Instructions

  1. Combine all ingredients, except egg slices, in a medium bowl and stir to blend.
  2. Spoon the mixture into a 10 x 6-inch baking dish.
  3. Bake at 325°F (163°C) for 25 to 35 minutes or until bubbly and heated through.
  4. Garnish with hard-cooked egg slices if desired.

Tips & Substitutions

For a creamier texture, consider substituting half of the evaporated milk with sour cream. If you prefer a bit of crunch, you can add crushed potato chips on top before baking. For a vegetarian option, replace tuna with a mixture of sautéed mushrooms and spinach. This dish is versatile and can be enhanced with different cheeses or vegetables.

Serving Suggestions

Serve this colorful casserole with a fresh green salad or steamed vegetables for a balanced meal. It also pairs wonderfully with crusty bread or garlic bread for a comforting dinner. For a festive touch, consider garnishing with fresh parsley or serving alongside an appetizer like Mott'S Family Crab Cakes for a delightful seafood-themed meal.

Storage & Reheating

Allow the casserole to cool completely before storing leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) for about 15-20 minutes until warmed through, or microwave in short intervals, stirring in between to ensure even heating.
