Easy Spaghetti Casserole Recipe

Some nights, spaghetti sounds perfect, but I want something a little easier to serve and a little more comforting than a pot of pasta and sauce. That is when I make this spaghetti casserole recipe.

With three kids, baked pasta works especially well at our house because I can assemble everything before dinner gets hectic, put the dish in the oven, and serve it straight from the baking dish. The spaghetti stays saucy, the seasoned beef makes it filling, and the melted mozzarella creates those golden cheesy spots everyone reaches for first.

This easy spaghetti casserole uses familiar ingredients rather than a long list of extras. You get spaghetti, halal ground beef, marinara, garlic, herbs, Parmesan-style cheese, and mozzarella. It tastes like a cozy spaghetti dinner but has the convenience of a casserole.

If your family enjoys easy pasta-and-beef dinners, my Hamburger Noodle Casserole is another simple weeknight option.

Why You’ll Love This Spaghetti Casserole Recipe

This spaghetti casserole recipe turns basic pantry ingredients into a complete family dinner.

The ground beef adds plenty of savory flavor, while marinara keeps the spaghetti moist during baking. Mozzarella melts over the top and gives the baked spaghetti casserole its comforting, bubbly finish.

I also like that this recipe does not depend on several rich cheese layers. That keeps it different from a Million Dollar Spaghetti-style casserole and lets the tomato sauce, beef, and pasta remain the main flavors.

You will also love that this cheesy spaghetti casserole:

• Uses simple grocery-store ingredients.
• Feeds about eight people.
• Works well with leftover portions.
• Can be assembled ahead of time.
• Uses one baking dish for serving.
• Freezes well.
• Gives you plenty of ways to add vegetables.
• Works with halal ground turkey or chicken too.

For a busy family dinner, this ground beef spaghetti casserole is hard to beat.

Spaghetti

Regular spaghetti works best in this spaghetti casserole recipe.

Cook it slightly firmer than al dente. The noodles continue cooking after they go into the oven, so fully cooking them at the beginning can make the finished casserole too soft.

Ground Beef

Use lean halal-certified ground beef.

I usually choose lean beef because the casserole already has plenty of moisture from the sauce and cheese.

Marinara Sauce

Choose a marinara sauce you already like. Tomato, garlic, basil, and Italian herbs work especially well.

Avoid a very thin sauce because the spaghetti casserole needs enough body to hold together when served.

Cheese

Mozzarella gives this baked spaghetti casserole its melted top.

A little Parmesan-style cheese adds more savory flavor. For a halal-friendly dish, check that the cheese uses vegetarian or halal-certified enzymes.

Substitutions & Variations

This spaghetti casserole recipe is easy to customize.

You can replace the ground beef with halal-certified ground turkey or ground chicken. Poultry is usually leaner, so you may need a little extra olive oil while browning it.

For more vegetables, cook diced bell peppers or mushrooms with the onion. You can also stir chopped spinach into the marinara just before assembling the casserole.

For a spicier ground beef spaghetti casserole, add more red pepper flakes or use a spicy marinara sauce.

You can also replace some of the mozzarella with cheddar or Monterey Jack for a slightly different flavor.

If you want an even more substantial ground beef dinner, my Big Mac Casserole is another family-friendly option.

I would not add a thick cream cheese or ricotta layer to this particular spaghetti casserole recipe. We want this version to remain a classic tomato-and-beef baked spaghetti casserole rather than turning it into Million Dollar Spaghetti.

Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 375°F.

Lightly grease a 9×13-inch baking dish.

2. Cook the Spaghetti

Bring a large pot of salted water to a boil.

Add the spaghetti and cook it about 2 minutes less than the package directions for al dente.

Drain the spaghetti well.

Do not rinse it.

3. Brown the Ground Beef

Heat the olive oil in a large skillet over medium-high heat.

Add the diced onion and cook for about 3 minutes.

Add the halal ground beef and break it into small pieces with a wooden spoon.

Cook for about 6 to 8 minutes, until browned and completely cooked. For food safety, the USDA recommends cooking ground beef to a minimum internal temperature of 160°F, measured with a food thermometer.

4. Season the Meat Sauce

Add the minced garlic, Italian seasoning, paprika, salt, black pepper, and optional red pepper flakes.

Cook for about 30 seconds.

Pour in the marinara sauce.

Reduce the heat and simmer for about 5 minutes.

The sauce for this spaghetti casserole recipe should look thick and rich rather than watery.

5. Prepare the Spaghetti

In a large bowl, whisk the egg with the Parmesan-style cheese.

Add the warm drained spaghetti and toss quickly until evenly coated.

This light coating helps the baked spaghetti casserole hold together without making it heavy.

6. Assemble the Casserole

Spread about half of the spaghetti across the bottom of the prepared baking dish.

Spoon half of the beef marinara over the pasta.

Add the remaining spaghetti, followed by the rest of the meat sauce.

Gently spread everything evenly.

7. Add the Cheese

Sprinkle the mozzarella evenly over the top.

Make sure the cheese reaches close to the edges so every serving of cheesy spaghetti casserole gets some melted mozzarella.

8. Bake

Cover loosely with foil.

Bake for 20 minutes.

Remove the foil and bake for another 10 to 15 minutes, until the sauce bubbles and the mozzarella develops lightly golden spots.

9. Rest Before Serving

Remove the spaghetti casserole from the oven and let it rest for about 10 minutes.

This makes the casserole much easier to cut and serve.

Finish with fresh basil or parsley.

Pro Tips for Success

The biggest mistake with any spaghetti casserole recipe is overcooking the pasta before it goes into the oven.

Keep the spaghetti slightly firm. It absorbs moisture from the marinara as the casserole bakes.

Use a thick marinara rather than a watery tomato sauce. Too much liquid can make the bottom of the baked spaghetti casserole loose.

Drain excess grease from the beef before adding the marinara.

Freshly shredded mozzarella also melts more smoothly than many packaged shredded cheeses.

Do not skip the resting time either. Ten minutes allows the sauce and pasta to settle so you can serve neat portions rather than a pile of loose noodles.

Storage & Reheating Tips

Allow leftover spaghetti casserole to cool before transferring it to airtight containers.

Store it in the refrigerator for 3 to 4 days.

For individual portions, microwave until hot throughout.

If the pasta looks slightly dry, add a spoonful of marinara before reheating.

For several portions, cover the casserole with foil and reheat it at 350°F until hot.

The USDA also recommends refrigerating cooked leftovers promptly and using most refrigerated leftovers within 3 to 4 days.

Can You Freeze Spaghetti Casserole?

Yes. This spaghetti casserole recipe freezes well.

Cool the casserole completely, then divide it into freezer-safe portions.

For best quality, use frozen portions within about 2 to 3 months.

Thaw them overnight in the refrigerator before reheating.

Make-Ahead Instructions

You can assemble the ground beef spaghetti casserole up to a day before baking.

Cover the dish tightly and refrigerate it.

When you are ready to cook, place the casserole in the oven and allow about 5 to 10 extra minutes because the ingredients are starting cold.

What to Serve With This Recipe

Because this spaghetti casserole recipe already combines pasta, beef, tomato sauce, and cheese, simple sides work best.

A crisp green salad with vinaigrette adds freshness.

Roasted broccoli, asparagus, zucchini, or green beans also pair nicely with the rich marinara.

Garlic bread is another classic choice, especially if your family likes soaking up the sauce left on the plate.

You can also serve this easy spaghetti casserole with a simple cucumber and tomato salad for something lighter.

FAQs

Can I make spaghetti casserole ahead of time?

Yes.

Assemble the spaghetti casserole recipe, cover the baking dish, and refrigerate it for up to 24 hours.

Bake when needed, adding a few extra minutes because the casserole starts cold.

Can I use leftover spaghetti?

Yes, as long as the spaghetti has not already become very soft.

Leftover pasta works particularly well if it was originally cooked al dente.

Can I make spaghetti casserole without ground beef?

Absolutely.

Leave out the meat and add sautéed mushrooms, zucchini, bell peppers, or spinach for a vegetable version.

What cheese is best for spaghetti casserole?

Mozzarella is my first choice because it melts beautifully and has a mild flavor.

You can combine it with Parmesan-style cheese, cheddar, or Monterey Jack.

Why is my spaghetti casserole watery?

A thin marinara sauce, excess grease from the ground beef, or watery vegetables can all create extra liquid.

Drain the beef and cook vegetables before adding them to your spaghetti casserole.

Can I use another pasta shape?

Yes, although technically it will no longer be a traditional spaghetti casserole recipe.

Penne, rigatoni, and ziti work well with the same beef-and-marinara mixture.
