Some nights call for a casserole, and this baked spaghetti and meatball situation is the one I make when I need to feed a crowd or just want leftovers for days. It takes everything you love about classic spaghetti and meatballs and bakes it into a cheesy, bubbly dish that you can scoop into big comforting squares.
This is the meal I bring to new moms, drop off for a friend having a hard week, or make on a Sunday so we are set for a couple of busy weeknights. It is humble and a little nostalgic and exactly the kind of food that makes a house feel like home.

The little trick that holds it all together
Tossing the warm spaghetti with a couple of beaten eggs and parmesan before layering is the secret. It sets up just enough in the oven so your casserole slices into tidy portions instead of sliding all over the plate. It is a small step that makes a big difference.
I am all about shortcuts here. Use your favorite jarred marinara and frozen meatballs and nobody will ever know. Some nights are for homemade everything, and other nights are for getting dinner on the table before the meltdowns start. Both are valid.
Make ahead and freezer tips
You can assemble the whole thing a day ahead and keep it covered in the fridge, then bake when you are ready. It also freezes beautifully. I like to build it in a foil pan, freeze it unbaked, and pull it out on a week when I know I will have zero energy to cook. Future me is always so grateful.
Serve it with a simple salad and some garlic bread and you have a dinner that feels like a warm hug. My kids ask for seconds every single time.
