This oven-baked sausage and pepper ziti is the kind of no-fuss comfort food that earns a permanent spot in the weeknight rotation. Sweet Italian sausage, tender bell peppers, jarred marinara, and ziti — that’s it. Everything goes into one skillet, then one baking dish, and comes out tasting like you put in way more effort than you actually did. Four ingredients. No fuss. Done.
Why You’ll Love It
- Only 4 ingredients — sausage, peppers, pasta, and a jar of marinara. That’s the whole list.
- One skillet, one baking dish — minimal cleanup for a meal that tastes like serious effort.
- Those crispy edges — baking uncovered for the last few minutes gives you golden, slightly caramelized bits that are absolutely the best part.
- Great the next day — maybe even better cold out of the fridge at midnight. Not that I’d know anything about that.
- Crowd-pleaser, every time — nobody ever asks if there’s something else when this is on the table.
A Few Notes on the Ingredients
The sausage matters more than anything else here. I use sweet Italian links, always — I slice them into rounds instead of taking the casing off and crumbling them, because I like having actual pieces of sausage in the dish. You can feel each one. The hot Italian version works too if your family likes heat; I’ve made it that way when I ran out of the sweet kind and didn’t feel like going back out, and it’s honestly very good. Spicier, obviously, but good.
The peppers — I use whatever I have. Honestly. Red ones are sweeter and look prettier, green ones have that slightly bitter edge that I actually love against the sausage, yellow and orange are somewhere in the middle. I’ve thrown in a mix before because I had half a red and half a green sitting in the drawer looking at me. It works. Don’t overthink the peppers.
The marinara is from a jar. I know. I have no shame about this. I’ve tried making this with homemade sauce and the difference is — fine, I’ll say it — not worth it for this particular dish. The jar sauce is part of what keeps it easy. I like a marinara that’s a little chunky with some herbs in it, nothing too sweet. Whatever you like on pasta you’ll like here.
Ingredients
- 12 ounces dried ziti (penne works in a pinch — I’ve done it)
- 1 pound sweet Italian sausage links, sliced into rounds, about half an inch thick
- 2 medium bell peppers, any color, cored and sliced thin
- 24 ounces jarred marinara sauce (about 3 cups)
- A little olive oil for the pan, a pinch of salt and pepper — these barely count as ingredients
Let’s Make It
Start by getting a big pot of water going with a good amount of salt — salt it well, the water should actually taste seasoned. Cook the ziti until it’s just slightly underdone. You’ll see on the package what the time is — knock a minute or two off that. The pasta finishes in the oven, and if you cook it all the way through now it gets mushy later and nobody wants that.
While the pasta’s going, heat up a skillet — I use my big cast iron one but any heavy pan works — and get the sausage rounds in there. Give them room. Let them sit and brown. This is the part where you need to be a little patient and not stir them too much, which I always have trouble with because I’m a stirrer by nature. But if you leave them alone for a few minutes you get this nice golden crust on the edges and it makes a real difference. Once they’re browned and cooked through, push them to one side and add your peppers. Cook those down until they’re soft but not completely limp — they’ll keep cooking in the oven so you want them to still have a little life in them at this point.
Pour the marinara in, stir everything together, let it come up to a simmer. Taste it. Add salt and pepper if it needs it — the sausage brings a lot of seasoning on its own, so I usually don’t add much. Then add your drained ziti right into the skillet and fold it all together until every piece of pasta is coated.
Into a greased 9×13 baking dish it goes. Cover it tightly with foil — this is important, you want the steam to stay in there — and bake at 375°F for about 20 to 25 minutes, until the sauce is bubbling around the edges. If you want a little crispiness on top, pull the foil off for the last five minutes. I almost always do this because those crispy edge pieces are worth fighting over.
Let it sit for five minutes before you serve it. I know that’s hard. But it helps everything settle.
Variations
Chicken sausage works really well here if you want something lighter — a little less rich, but still good. Some people add mushrooms to this, which I think is unnecessary, but it does work. Their kitchen, their mushrooms.
I’ve stirred in a handful of fresh Spinach right at the end before transferring to the baking dish, and it wilts in nicely. You can’t really taste it but it makes me feel better about myself. If you want cheese — and I get it, I really do — sprinkle some mozzarella over the top when you pull the foil off for those last five minutes. It’ll melt and bubble and be beautiful. It’s not in the base recipe to keep it a true four-ingredient meal, but honestly, nobody is going to stop you.
Leftovers
It keeps well, covered in the fridge, for three or four days. Reheat it in the microwave with a small splash of water if it looks dry, or in a low oven if you have the time. I’ve been known to eat it cold, as mentioned. I’m not going to pretend that’s not something I do.
I always serve this in a big glass bowl in the middle of the table, family style, with a green salad and some crusty bread because you’ll want something to mop up the sauce at the bottom. There’s always sauce at the bottom. That’s the good part — the part everyone tries to get to first and nobody admits to trying to get to first.
I meant to say earlier that this reheats beautifully, but also — it almost never lasts long enough to reheat. That’s probably the better ending to this whole thing.
