Step 1
Start by heating your oven to 350 degrees F (175 degrees C). In a 9x5-inch loaf pan, mix together the cream of celery soup, Cheddar cheese, milk, sour cream, mayonnaise, tuna, parsley, lemon juice, salt, and pepper until everything is well combined. Stir the cooked pasta into the sauce, making sure it’s all nicely coated. Sprinkle the bread crumbs evenly over the top. Pop it in the oven and bake for about 45 minutes, or until the bread crumbs turn a lovely golden brown and the sauce is bubbling. Let it cool for a few minutes before serving.
