Creamy Dill Tuna Casserole is the ultimate comfort food with a fresh twist. This dish combines the heartiness of a classic casserole with the vibrant flavor of dill, making it a perfect go-to for busy weeknights or cozy weekends.
Elbow macaroni provides the perfect base for soaking up the creamy sauce. Tuna adds protein and a mild flavor that pairs beautifully with the dill. Frozen peas bring a pop of color and sweetness, while celery and onion add crunch and depth. Butter helps sauté the veggies, enhancing their flavors. The cream of mushroom soup acts as the creamy backbone, melding everything together. Milk and sour cream smooth out the sauce, while cheddar cheese adds richness. Fresh dill is the star herb, infusing the dish with its distinctive taste. A bit of salt and black pepper seasons the casserole to perfection. Finally, breadcrumbs mixed with olive oil create a crispy, golden topping.
This casserole pairs beautifully with a simple green salad drizzled with a lemon vinaigrette. A side of crusty bread or garlic toast works wonderfully for a complete, satisfying meal. For a little extra flair, garnish with additional fresh dill before serving.
Start by preheating your oven to 350°F (175°C). This ensures it's ready to go once the casserole is assembled. While the oven heats, cook the elbow macaroni according to the package directions. Once done, drain and set it aside. Next, take a large skillet and melt the butter over medium heat. Add the chopped celery and onion, sautéing until they're soft and fragrant.
In a large bowl, combine the cream of mushroom soup, milk, sour cream, and cheddar cheese. Stir in the fresh dill, salt, and black pepper. Once the sauce is well mixed, add the cooked macaroni, tuna, peas, and sautéed vegetables. Give it all a good stir so everything is well coated with the sauce.
Grease a 9x13-inch baking dish lightly, then transfer the mixture into it, spreading it out evenly. In a small bowl, mix the breadcrumbs with olive oil until they're well coated. Sprinkle this mixture over the top of the casserole for a crispy finish. Bake in your preheated oven for 25-30 minutes until the top is golden brown and the casserole is heated through.
