This oven-baked wedding soup pasta takes everything you love about Italian wedding soup — the little meatballs, the broth, the greens — and turns it into a hearty, fuss-free Casserole with just four ingredients. No boiling pasta, no babysitting a pot. You layer it raw right in the dish, let the oven do the work, and dinner is done.
Why You’ll Love This One
- Truly just four ingredients — pasta, brothy sauce, frozen meatballs, fresh spinach. No footnotes, no hidden extras.
- No pre-cooking the pasta — it goes in dry and soaks up all that savory broth right in the oven.
- Looks like you tried harder than you did — the meatballs get a little color, the spinach goes silky and deep green, the edges bubble. It’s a dish that earns compliments.
- Feeds a crowd without fuss — one 9×13 pan, minimal prep, and dinner is handled.
A Word About the Ingredients
The pasta: small shapes only. Ditalini is my first choice, the same little tube-shapes you’d find in an actual wedding soup, but I’ve made this with elbows and small shells and honestly it all works. What you don’t want is anything big or long. Penne would be weird. Spaghetti broken into pieces would be a disaster. Small shapes hold up to the baking time without turning to mush, and they fit nicely on a serving spoon alongside the meatballs.
The sauce: needs to be brothy. Not a thick tomato sauce, not a jar of marinara. You’re looking for something that’s closer to a soup base, something with that Chicken-broth foundation that Italian wedding soup has. Some grocery stores carry brothy pasta sauces, and others don’t, so you might have to look around a little. If you genuinely can’t find a brothy version, you could probably use a good jarred chicken broth concentrate and a splash of tomato, though I haven’t tried that myself.
The meatballs: frozen, fully cooked, mini. That’s it. No judgment about brand. I’ve used several and they all come out fine. The point is that they’re small enough to cook through without any extra work, and they’re already seasoned, which means you don’t have to think about it.
Spinach: fresh, not frozen. Fresh baby spinach wilts down into something genuinely beautiful in this dish. Frozen tends to release extra water and can make things soggy. Just roughly chop it, don’t stress about it being perfect.
Ingredients
- 12 oz small pasta — ditalini is what Grandma would use, elbows work too
- One 24 oz jar of brothy chicken-based pasta sauce or soup base (not marinara, not thick)
- 16 oz bag of frozen fully cooked mini meatballs
- 4 big packed cups of fresh baby spinach, roughly chopped — maybe a little more if you like it
How to Make It
First, preheat your oven to 375°F and grease a 9×13 casserole dish. Nothing fancy. A little cooking spray, a swipe of butter, whatever you have.
Pour the dry pasta straight into the bottom of the dish. I know it feels wrong. Do it anyway.
Pour the sauce over the pasta and use a spoon to push the liquid into all the corners. You want every piece of pasta to have contact with liquid, otherwise you’ll end up with crunchy bits around the edges that didn’t soften all the way.
Tuck the meatballs in. They don’t need to be arranged perfectly — just distribute them so that when you serve it, every portion gets a few.
Pile the spinach on top. All of it. It will look like far too much. It is not too much. It will shrink down to almost nothing once the heat gets to it, and you will be glad you used the whole four cups.
Cover the dish tightly with foil and bake for 35 to 40 minutes. The foil traps the steam and that’s what actually cooks the pasta. This is not the time to peek.
When you pull it out, take the foil off carefully — there will be a real cloud of steam — and give everything a gentle stir from the edges toward the center. If it looks a little dry, splash in some broth. If it looks fine, leave it alone. Put it back in the oven uncovered for another five to ten minutes, just until the top gets a little golden in spots and the edges are bubbling.
Let it rest for ten to fifteen minutes before serving. The pasta needs that time to settle or it’ll be too loose when you try to scoop it.
Variations
My daughter has been making a version with Parmesan cheese scattered over the top before the last stretch of baking, and I have to admit it forms a nice salty little crust. I’m not adding it to the official recipe because then it’s five ingredients, but I understand the impulse.
If you want it soupier — more like actual wedding soup — stir in a cup or two of hot chicken broth right after you take it out of the oven. It loosens up into something you could almost ladle.
Frozen peas or carrots stirred into the pasta before baking adds color and a little Sweetness, though technically that’s five or six ingredients, and you lose the simplicity that makes this dish worth making on a tired Tuesday evening.
Leftovers
Into the fridge within two hours, eat within three or four days. The pasta absorbs more liquid as it sits, so when you reheat it, just add a splash of broth or even a little water and stir it through. It reheats fine in the microwave, though I usually do it in a small pan on the stove because I prefer the texture that way.
Don’t leave it on the counter. Refrigerate it.
Final Notes
I serve this with a green salad and some kind of bread, usually whatever rolls I remembered to pick up or garlic toast if I’m feeling ambitious. Lemon bars for dessert, or store-bought angel food cake with strawberries on top. Nothing fancy. That’s the whole spirit of this meal, really — nothing that asks too much of you.
