Should I undercook the pasta for baked spaghetti?

Yes — two minutes less than the package time. The pasta continues absorbing sauce and softening in the oven, so fully cooked spaghetti going in comes out mushy.

Can I use jarred sauce?

Absolutely, and most of the time I do. Simmering it for ten minutes with the browned beef, garlic and Italian seasoning makes a real difference to how homemade it tastes.

Why is my baked spaghetti dry?

Not enough sauce. Pasta drinks up far more liquid in the oven than people expect, so err generous — add a half cup of water to the jar of marinara and don't skimp when you toss.

Can I make baked spaghetti ahead of time?

Yes. Assemble it fully, cover and refrigerate for up to two days, then bake from cold with an extra 15 minutes under foil. It also freezes unbaked for 3 months.

Baked Spaghetti (Cheesy Comfort Food That Feeds Eight)

By Ami · September 11, 2026 · ★★★★★ 4.8 from 241 reviews · Jump to Recipe · Print

Baked spaghetti is the comfort food recipe that turns an ordinary pot of pasta into something worth putting on the table for company. Meat sauce, pockets of ricotta and a full blanket of mozzarella, baked until the edges go crisp.

It's easier than lasagna and nearly as good.

No layering discipline required. Everything gets tossed together and spread in a dish. All the satisfaction of baked ziti with even less assembly.
The ricotta goes in as pockets, not a layer. Dotted across the top of the pasta it stays creamy and distinct instead of smearing into the sauce.
Crispy edges are the best part. The strands that touch the dish go golden and slightly chewy, which is something a bowl of spaghetti can never give you.

Here's what you'll need.

Low-moisture mozzarella is important here — fresh mozzarella releases water and will leave a puddle on top.

Ingredients for baked spaghetti: dry spaghetti, ground beef, onion, garlic, marinara, mozzarella and ricotta

Here's how it all comes together.

Step 1 — Undercook the pasta

Boil the spaghetti two minutes short of the package time. It keeps cooking in the oven, and fully-cooked pasta going in comes out soft.

Step 2 — Brown the beef

Cook the ground beef with the onion and garlic until well browned. Drain off the excess fat before the sauce goes in.

Step 3 — Build the sauce

Add the marinara and Italian seasoning and let it simmer for ten minutes. Even jarred sauce improves with a short simmer alongside the beef.

Step 4 — Toss it all together

Combine the drained spaghetti with the meat sauce in a large bowl, using tongs so every strand gets coated.

Step 5 — Into the dish with ricotta

Spread the saucy spaghetti into a baking dish and dot spoonfuls of ricotta across the surface, pressing them in slightly.

Step 6 — Cheese and bake

Cover with mozzarella and parmesan and bake at 375°F for 25 minutes until golden and bubbling at the edges.

Things I learned while testing this recipe.

More sauce than you think. Pasta absorbs a surprising amount in the oven. A batch that looks slightly too saucy going in comes out exactly right.
Season the ricotta. Plain ricotta is bland. Stir in salt, pepper and a handful of parmesan before dotting it on and those pockets actually taste of something.
Foil for the first half. Covered for 15 minutes then uncovered for 10 gets the middle hot without burning the cheese.
Rest before cutting. Ten minutes lets it set enough to lift out in squares rather than sliding onto the plate.

Why this is a great dish to make ahead.

Assemble up to 2 days early and bake straight from the fridge with an extra 15 minutes under foil.
It freezes unbaked for 3 months. Wrap the dish in foil then plastic, and bake from frozen at 350°F for about 75 minutes.
Leftovers reheat as squares, which makes it one of the tidiest pasta dishes for weekday lunches.

Here's what I'd serve with this.

Garlic bread — obligatory, and it can go in the oven for the last ten minutes.
Mediterranean chickpea salad for something fresh against all that cheese.
Roasted cauliflower roasted on the shelf below while the pasta bakes.
Eggplant parmesan if you want a second Italian-American dish for a crowd.
Apple crisp for dessert while the oven is still warm.

Just in case you have leftovers.

Storing: Cover and refrigerate for up to 4 days. Baked spaghetti holds its shape well, so leftover squares cut cleanly straight from the fridge.

Reheating: Reheat covered at 350°F for 20 minutes, or microwave a portion at 70% power with a spoonful of extra marinara over the top to keep it from drying out.

Baked Spaghetti

★★★★★ 4.8 from 241 reviews — Spaghetti tossed in a rich meat sauce, dotted with seasoned ricotta and baked under a blanket of melted mozzarella until bubbling and golden.

Prep 20 min · Cook 25 min · Total 45 min · Serves 8 · Category: Comfort Food · Cuisine: Italian-American

Ingredients

1 lb dry spaghetti
1.5 lb ground beef (85/15)
1 large yellow onion, diced
4 cloves garlic, minced
1 jar (32 oz) marinara sauce, plus 1/2 cup water
1 tablespoon Italian seasoning
15 oz whole-milk ricotta
3 cups low-moisture mozzarella, shredded
3/4 cup grated parmesan, divided
Kosher salt, black pepper and fresh basil

Instructions

Cook the pasta. Boil the spaghetti in well-salted water for 2 minutes less than the package directs, then drain.
Brown the beef. Cook the ground beef with the onion and garlic in a large skillet until well browned. Drain excess fat.
Simmer the sauce. Add the marinara, water and Italian seasoning and simmer 10 minutes. Season to taste.
Combine. Toss the drained spaghetti with the meat sauce until every strand is coated.
Season the ricotta. Stir 1/4 cup of parmesan, salt and pepper into the ricotta.
Assemble. Spread the pasta into a 9x13 dish, dot the ricotta across the surface, and cover with the mozzarella and remaining parmesan.
Bake. Bake covered at 375°F for 15 minutes, then uncovered for 10 minutes until golden and bubbling. Rest 10 minutes and finish with basil.

Notes: Italian sausage in place of half the beef adds a lot of flavor. For a vegetarian version, swap the meat for sautéed mushrooms and zucchini — just cook off their water first so the dish doesn't go soupy.
