• 1 pound lean ground beef
• ½ medium onion, chopped
• ½ teaspoon dried oregano or Italian seasoning
• ½ teaspoon crushed red pepper flakes (optional, but adds a little zing)
• 4 cloves garlic, minced
• 4 cups marinara sauce (that’s one 24 oz jar + a bit of another)

Instructions to Make Easy Baked Spaghetti

Making Easy Baked Spaghetti isn’t just about tossing pasta into a dish and covering it with cheese—though that is part of the delicious fun. Here’s your step by step guide to get from “what’s for dinner?” to “can I have seconds?” in under an hour. This walk-through is designed to be super approachable, even if you’re juggling a toddler on your hip or working with whatever’s in your pantry. Let’s dive in.

Step 1: Preheat the Oven and Boil the Pasta

First things first—preheat your oven to 375°F and move your oven rack to the top third. This is key to getting that golden, bubbly cheese topping we all love. While your oven is warming up, bring a large pot of well-salted water to a boil. (Pro tip: the water should taste like the ocean—don’t skimp on the salt.)

Now cook your spaghetti, but here’s the trick: boil it for 2 minutes less than the package directions. Why? Because it’ll finish cooking in the oven, soaking up all that saucy, cheesy goodness without turning into mush. Once cooked, drain and immediately transfer it to a 9×13 casserole dish. No need to oil the noodles—they’re about to get cozy in marinara sauce anyway.

Step 2: Brown the Beef and Sauté the Aromatics

Grab a large skillet and toss in 1 pound of ground beef, the chopped onion, oregano, and crushed red pepper flakes (if using). If your beef is extra lean, drizzle in about a tablespoon of olive oil to help things along. Cook over medium-high heat, stirring occasionally, until the beef is nicely browned and the onions are soft—about 10 minutes.

If there’s a big puddle of fat at the bottom of the skillet, go ahead and spoon most of it out. (Nobody wants greasy spaghetti.) This step by step browning process really builds the base flavor, so don’t rush it.

Step 3: Add Garlic and Marinara Sauce

Once your meat is browned and smelling delicious, toss in the minced garlic and cook for just about 1 minute—until fragrant but not burnt. Then pour in 4 cups of marinara sauce (which is usually one full jar plus a bit of a second). Stir it all together and let it warm through for a few minutes. Give it a taste and season with salt and pepper as needed.

This is where you can jazz it up—if your sauce is on the sweeter side, add a pinch of red pepper flakes or a dash of balsamic vinegar. If it’s too tart, a teaspoon of sugar helps balance things out.

Step 4: Mix the Pasta with the Sauce

Now it’s time to bring everything together. Pour the warm meat sauce right over the drained spaghetti in your casserole dish. Use tongs or a big spoon to toss the noodles gently, making sure everything is well coated. You want every strand to get some of that savory sauce clinging to it. Once mixed, use a spatula to smooth everything into an even layer so it bakes up evenly.

Step 5: Add the Cheese Layers

Sprinkle the top with your shredded cheeses—mozzarella, cheddar, and parmesan. You can mix them together in a bowl first or layer them one at a time—it’s your call. If you’re short on time, a bagged shredded blend works fine, but grating your own cheese gives better melt and flavor.

Cheese tip: Parmesan adds that salty umami punch, while cheddar brings the boldness, and mozzarella gives you those melty cheese pulls. Feel free to tweak the ratios based on what you like or have on hand. For more cheesy casserole ideas, check out our creamy Million Dollar Chicken Casserole.

Step 6: Bake and (Optional) Broil

Place the casserole dish uncovered into your preheated oven and bake for 20 minutes. This allows the cheese to melt and the whole dish to heat through. If you’re a fan of golden, slightly crispy cheese edges (and really, who isn’t?), flip on the broiler for an extra 2 to 3 minutes. Just keep an eye on it—cheese can go from golden to scorched in the blink of an eye.

Step 7: Let It Rest and Serve

Once out of the oven, let your Easy Baked Spaghetti rest for 5 to 10 minutes. This might feel like an eternity when your kitchen smells like an Italian bistro, but it’s important. Resting lets everything set up, so your spaghetti doesn’t fall apart when you cut into it. Slice it into squares using a spatula and serve hot.

Top with chopped parsley if you’re feeling fancy, or keep it simple—it’s delicious either way.

What to Serve with Easy Baked Spaghetti

This is a hearty dish, so you don’t need much on the side—but a few simple pairings take the meal from “Tuesday dinner” to “wow, you really planned this out!” A crisp green salad with a tangy vinaigrette balances out the cheesy richness of the pasta. Garlic bread (obviously) is a go-to—you can even make it while the spaghetti bakes. Roasted veggies like broccoli or zucchini are great if you want to sneak in some greens. Or, keep it cozy with sautéed green beans or a quick batch of air fryer Brussels sprouts. Want a full Italian-style vibe? Serve with a little Stovetop Tuna Noodle Casserole on the side for a throwback twist.

Key Tips for Making Easy Baked Spaghetti

First, don’t overcook the spaghetti. It’ll keep cooking in the oven, and mushy noodles aren’t anyone’s idea of fun. Second, grate your own cheese if you’ve got the time—it melts better and tastes richer than the pre-shredded kind. If you’re feeling short on time (who isn’t?), a bagged mozzarella-cheddar mix works too.

Third, season that sauce! Even the best jarred marinara can use a little boost, so taste it as you go. Also, that broil step? It’s optional, but if you want that golden-brown cheesy top, it’s so worth it. And finally—let it rest. Giving the spaghetti a few minutes out of the oven helps it set up, so it’s easier to slice and serve. No one wants a cheesy lava flow all over the plate.

Storage and Reheating Tips for Easy Baked Spaghetti

Got leftovers? Lucky you. Easy Baked Spaghetti stores like a dream. Let it cool completely, then cover tightly or transfer to an airtight container. It’ll keep in the fridge for up to 4 days. For longer storage, freeze individual portions wrapped in foil or packed in freezer containers—great for work lunches or nights you don’t want to cook. To reheat, pop a slice in the microwave with a splash of water (prevents it from drying out), or warm in the oven at 350°F covered with foil until heated through. Bonus tip: This recipe tastes even better the next day. The flavors mingle, the cheese firms up just right, and it slices like a champ.
