Creamy Tuna Broccoli Casserole

A warm and cozy creamy tuna broccoli casserole that’s ready in under an hour, blending tender broccoli, flaked tuna, and a silky cheese sauce for a comforting meal.

  • Total Time: 45 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • 2 cans tuna (4.5 oz each), drained and flaked
  • 1 pound broccoli, cut into bite-size pieces
  • 8 oz cream cheese
  • 1 cup heavy cream
  • 2 tablespoons unsalted butter
  • 1 cup cheddar cheese, shredded
  • 1/2 cup mozzarella, shredded (for topping)
  • 2 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper

Instructions

  1. Preheat oven to 375°F. Lightly grease a 9×13-inch baking dish and set aside.
  2. Steam or blanch broccoli for 2–3 minutes until bright green and slightly tender, then drain well.
  3. In a medium saucepan over low heat, melt butter and add cream cheese, stirring until smooth. Whisk in heavy cream, garlic, Italian seasoning, salt, and pepper; then stir in shredded cheddar until melted and combined.
  4. Gently fold flaked tuna and cooked broccoli into the sauce until evenly coated, then transfer the mixture to the prepared baking dish.
  5. Sprinkle the shredded mozzarella evenly over the top and bake at 375°F for 20–25 minutes, until bubbly and golden around the edges. Let rest 5 minutes before serving.

Notes

Serve over steamed rice or cauliflower rice. For a lighter version, swap heavy cream for half-and-half. Leftovers keep for 3-4 days, reheat covered in the oven.
