Why you’ll love it

This cheesy beef and pasta casserole is sure to be a hit with the kiddos. It’s also easily adaptable based on what you’ve got in the fridge/pantry/etc. You could throw in some extra veggies if you want. It’s very tasty for how few ingredients are in this budget-friendly meal.

I wasn’t sure whether to call this a casserole or ground beef pasta bake or what. Basically, you just boil up some penne, and while that’s cooking, you make a quick tomato and meat sauce. You then toss it together in a casserole dish, top it with cheese, and bake. It couldn’t be easier!

What you’ll need

  • Penne – I like this shape because it’s sturdy and holds up great in casseroles with the sauce and cheese
  • Onion and garlic – our tasty base aromatics. Sweet (Vidalia) onion is my go-to, but yellow works as well.
  • Ground beef – I used extra lean hamburger meat here. Aim for 90% or more.
  • Olive oil – for sautéing
  • Marinara sauce – just grab a jar of your favorite brand that you enjoy the taste of since it’s a key ingredient
  • Cheddar cheese – I grate my own from a block of cheddar for best taste and freshness

Pro tips

  • The ingredient quantities don’t have to be exact. A bit more or less beef will be totally fine. Want to add more sauce? Go ahead. Same with the cheese. Many readers like to use the entire jar of marinara sauce. It’s all good! 🙂 This recipe definitely can be adapted based on what’s in your pantry.
  • I recommend slightly undercooking any pasta/noodles so it doesn’t go mushy in the oven.
  • This recipe can easily be halved if you need a smaller quantity and made in an 8×8 dish instead.

How to make this ground beef casserole

This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.

sauteing ground beef in a skillet and adding marinara sauce

Preheat your oven, and grease a baking dish. Boil the pasta for a minute less than package directions. Meanwhile, add the oil, onion, and beef to a skillet. Sauté until cooked, adding the garlic once it gets going. Spoon out any excess fat, then pour in the marinara and warm through. Taste and season with salt & pepper as needed.

Drain the pasta, and add it to the baking dish. Pour the beef mixture over top, and toss to combine. Spread everything in an even layer. Top with the cheddar cheese, and bake uncovered until melty. Broil if desired to brown the cheese, and enjoy right away.

  • You’ll need a 9×13 baking dish for this casserole.
  • This is the garlic press I use to avoid the hassle of mincing garlic by hand, and I store the other half of the onion in the fridge in an onion saver for later.
  • Break apart the meat as it’s browning with this meat chopper.

Substitutions and variations

  • Any jarred tomato-based pasta sauce will work, or use a similar amount of tomato sauce or even a combo of tomato products such as diced tomatoes and tomato paste or crushed tomatoes. I’d then add in a bit of Italian seasoning or other herbs for more flavor.
  • You can substitute the penne with whatever pasta you have on hand or (even use egg noodles like some casseroles do).
  • Ground turkey or Italian sausage are other protein options instead of the beef, or you could do a mixture.
  • If you want to put a Tex-Mex spin on this hamburger pasta casserole, add in some beans, Taco Seasoning, and use a Mexican cheese blend.
  • For some veggie content, stir in some frozen mixed vegetables until thawed. Simply add to the skillet and cook for a couple minutes once the beef is browned.

Make ahead tips

  • Up to 1 day ahead: assemble it, cover and refrigerate, and then bake as directed below, possibly adding a few more minutes onto the time to ensure it’s cooked all the way through if it’s cold from the fridge.
  • Freezer instructions: assemble it, and then cover it tightly and store in the freezer for up to 3 months. Thaw for 24 hours in the refrigerator, then bake it as indicated. I would definitely recommend using more sauce for make-ahead methods.
  • Baking from frozen: warm it up on the counter for a bit so that the casserole dish doesn’t crack. It will take a little longer, so bake covered with foil until the middle is hot, and then broil the cheese at the end, watching carefully.

What to serve with this ground beef casserole

Leftovers and storage

  • Keep any leftovers of this beef casserole in a covered container in the fridge for 3-4 days.
  • Reheat in a saucepan over a low heat until warmed through, or microwave in short intervals. Since the pasta will absorb sauce over time, feel free to add a splash more marinara when reheating.
  • I generally don’t suggest freezing leftover pasta, but if you typically do that with success, go for it!

Simple Ground Beef Casserole

This ground beef casserole recipe is super easy to throw together and feeds a crowd! It's comforting and uses simple ingredients.
Prep: 10 minutes
Cook: 25 minutes
Total: 35 minutes
Servings: 6

Ingredients 

  • 1 pound uncooked penne
  • 1 tablespoon olive oil
  • 1 pound lean ground beef
  • 1/2 medium onion chopped
  • 1 clove garlic minced
  • 1.5 cups marinara sauce
  • Salt & pepper to taste
  • 1.5 cups shredded cheddar cheese

Instructions 

  • Preheat your oven to 400F and move the rack to the middle position. Grease a 9×13 baking dish (I use Pam spray).
  • Boil a large, salted pot of water for the penne. Cook it for 10 minutes (it should be slightly underdone so it doesn't get mushy).
  • Add the oil, beef, and onion to a skillet. Sauté over medium-high heat, breaking the meat up as you go along, for 10 minutes. Once it gets going, stir in the garlic. Spoon out excess fat if needed.
  • Stir in the marinara sauce and warm through. Give it a taste and season with salt & pepper as needed.
  • Drain the pasta and pour it into the baking dish. Pour the beef mixture over top and then toss until it's combined with the pasta. Top with an even layer of the cheese. If you want it extra cheesy, you can stir in an additional half cup of cheese prior to topping it with the rest of the cheese.
  • Bake for 10 minutes, uncovered, until the cheese is nicely melted. I then broil it for a few minutes (optional) to brown the cheese up a bit. Serve immediately.

Notes

  • This is a very flexible recipe where additions/substitutions/etc. are fine. I have some tips within the blog post.
  • You can also find this recipe in chapter 6 of the Salt & Lavender: Everyday Essentials hardcover cookbook.

    Very simple and delicious! I am always on the look out for easy dinner recipes and this ticked all the boxes. Great recipe! This oneโ€™s a definite keeper!

    1. Natasha says:

      Thank you!!

    The dish ending up being very good. There’s so much you can do with it. Add veggies, different cheese, etc… I will def be making it again.

    1. Natasha says:

      I’m thrilled to hear that!! Yes, it’s definitely a flexible recipe.

  3. Heather says:

    If you wanna throw the Tex mix twist on it would you still use the marinara?

    1. Heather says:

      Sorry Tex-Mex Twist.

    2. Natasha says:

      I think that should be fine since it’s a fairly basic-tasting tomato sauce… you could perhaps use a large jar of salsa instead, though.

  4. Kim says:

    If I am making this for another family, will it still taste okay if they put in the fridge for a day? Also, how long do you think they should cook it for if it’s coming out of a cold fridge?

    1. Natasha says:

      I think it’ll work fine to assemble it a day ahead. I’d probably have them bake it with foil to start with (like maybe for 30 minutes or so), and then bake it uncovered for another 20 min (approx.) or until it’s warmed through. Then they can broil if they wish to get the cheese all bubbly. It’s basically just about it being hot inside, so it’ll depend on their oven, so this is just a guess. You may want to add a little more sauce since it’ll be sitting in the fridge and the pasta may soak it up a bit.

    Iโ€™m glad i found this recipe, so simple and delicious for an easy meal, perfect when you donโ€™t want to be in the kitchen too long.

    1. Natasha says:

      Excellent! So glad you enjoyed it!

  6. Anna says:

    Do you think Alfredo sauce would be a good substitute for the marinara sauce. My family is not big on marinara or any other kind of red sauce.

    1. Natasha says:

      Hi! I think it could be ok. Part of me is slightly worried it could separate in the oven, but I have done baked pasta with Alfredo sauce before and it’s worked out fine. Let me know if you try!

      1. Anna says:

        It is amazing with the Alfredo sauce and I added some boiled potatoes tastes amazing!

        1. Natasha says:

          Great!! ๐Ÿ˜€

      2. Lady says:

        Would mozzarella work instead of cheddar?

        1. Natasha says:

          Yes!

      I’m glad to have seen this to give my family a little different idea for dinner. Our family also isn’t a big fan of red sauce so going to try to sub for white sauce. Hoping it turns out okay. we don’t have potatoes but added some peppers in with the onion for a little extra something….. my family isn’t a huge fan of onion either except for me (mama) of course lol but we will see how it goes. In the process of cooking before the oven part. Thanks for adding the recipe. excited to try it

      1. Natasha says:

        Hi! I am wondering if you’re looking at a different recipe since there’s no potatoes in here unless it’s a typo lol. Please let me know how it goes!

    Going to give this a try tonight. Only difference I’m going to make is instead of plain marinara sauce I’m going to use the mushroom green pepper sauce I use for our spaghetti. This sounds delicious and I’m sure my kids will love it.

    1. Natasha says:

      Enjoy! I think that sauce would be good for sure. ๐Ÿ™‚

  8. Sara says:

  9. Jim B says:

    I was looking for a recipe that used ground beef and since I had everything on hand I thought I’d give it a try. I really liked it! The rest of the family liked it – even though the kids said it was “fine” and “all right”, they had seconds and they only do that if they like it. This one’s a keeper.

    1. Natasha says:

      That’s great!! So happy your kiddos liked it too. It can be tough feeding a whole family sometimes haha.
