Recipe By Stacy Zeigler
I love this dish because it is so family-friendly. A friend from church delivered this meal with a side salad and some garlic bread when my third daughter was born, and I was surprised to see my two- and four-year-old daughters love it as much as they did! I had to have the recipe. Over the years, I’ve tried making some changes, like using Italian sausage instead of hamburger and leaving out the mushrooms for a family that didn’t like them, but I always seem to return to the original recipe. When I first received it, the cream of mushroom soup caught me a little off guard. I wasn’t sure how it would fit in with a pasta dish, but it’s definitely the secret ingredient that makes it such a comforting meal.
Baked Spaghetti Casserole is the perfect combination of comfort and convenience, making it a great meal to share with family or bring to a friend in need. With its hearty layers of pasta, sauce, and melted cheese, it’s a crowd-pleaser that’s easy to prepare and transport. Whether you’re making it for a busy weeknight or as a thoughtful gesture, this dish is a delicious way to show you care!
