Crock-Pot Spaghetti Casserole

Mamma Mia . . . this is good spaghetti! Super cheesy and flavorful, it seriously rivals the baked spaghetti we’ve had in restaurants!

Crock-Pot Spaghetti Casserole

Total Time: 4-6 hours / Yield: 10 servings / Serving Size: 1-1/2 cups / Calories per serving: 409

3 cups Kraft Three Cheese shredded cheese
1 (15 oz) jar Light Alfredo sauce


  1. Spray crock-pot with non-stick cooking spray.
  2. Pour 1/2 of spaghetti sauce in bottom of crock-pot, and arrange 1/2 of the meatballs evenly on top of the sauce.
  3. Add uncooked, broken spaghetti.
  4. Sprinkle 2 cups of shredded cheese on top of spaghetti, and cover with Alfredo sauce.
  5. Add remaining spaghetti sauce, making sure spaghetti is completely covered.

  8. Cook on LOW heat for 4-6 hours until pasta is tender and meatballs are thoroughly heated.


Crock-Pot Spaghetti CasseroleSince nothing ever sticks in my crock-pot, I don’t spray it before cooking. If food sticks in yours, by all means, spray.

The recipe calls for approximately 32 frozen meatballs at 1/2 oz each. If you have larger (1 oz) meatballs, use just 16. You can use any type of meatballs you want; they don’t have to be Italian-style.

Be sure to use light Alfredo sauce. Otherwise, the dish will be too rich.

You can use any combination of shredded cheese you want to make up the 3 cups.

You’ll have to eyeball the serving size; there’s no easy way to measure.

IMPORTANT: This recipe appears to be hit-or-miss. What works for me isn’t necessarily working for everyone else (read the comments below). Undercooked pasta may be due to differences in crock-pot cooking temps . . . and how cheesy you prefer the dish appears to be relative—you either like a lot of cheese or you don’t. My best advice is to experiment and tweak the recipe to one that best suits you and your family. Share your results and email me a photo—I’ll be more than happy to post!


  1. Made this for a luncheon. It actually cooked 5 1/4 hours. The noodles are still nowhere near done. It does have a good flavor, though.

    • Seriously? I’m sorry to hear this and surprised. I’ve never had a problem. In fact, the whole thing is so bubbling hot after 4 hours, I would describe the pasta’s texture as “overdone” and a little mushy which is how it should be–it adds to the gooey goodness. My son, who is no cook, made the dish a couple of times and raves. So sorry it didn’t work out for you.

  2. I made this for the third time tonight. The first time it was absolutely incredible tasting! The second time, no one liked it because it was too cheesy and stuck to the roof of your mouth. I went back and thought about it, and I somehow missed all the cheese the first time! I made it again tonight without the cheese and the alfredo sauce gives it exactly what my family likes!

    • It is super cheesy. The next time I make it, I’m going to eliminate the cheese and try it your way with just the alfredo sauce. Sounds good!

    • UPDATE: The girl who gave me this recipe brought in the dish for a potluck. It was delicious and not too cheesy. I asked her again for the recipe, and lo a behold— she made a point of reminding me she uses light Alfredo sauce because she thinks using regular makes it too “rich.” I use light Alfredo sauce, but when I checked the recipe I had posted, I could see I had it wrong. I apologize. This could be, and most probably is, the reason why the dish was too cheesy and thick. I’ve corrected the recipe.

  3. I was Looking for a low cost, simple recipe and this was it. It came out perfect and tasty. Thanks for posting :)

  4. Trying this for the first time today but have to cook for 3 hours on high to make dinner time. Hope it works!!

  5. This recipe looks amazing! I’m going to make it later this week for a sorority potluck. I will let y’all know how it goes! :)

  6. Thank you for saving the night. Our 26 year old son and friends are coming in and since this was all in the house dinner was an easy treat. I just cut there cheese amount in half and it was a feast. Thanks for the share!

  7. I made this a couple weeks ago and everyone loved it! Making again tonight, but short on cheese so only using 2 cups.

  8. Hi – thank you for sharing your recipe. I just tried it – I had the same issue as another poster. My spaghetti did not cook – is there something I could do differently – add water maybe? What would you recommend? I would like to try it again.
    Thank you.

    • I have no idea why the spaghetti didn’t cook for you. I’ve never had a problem with the recipe. Are you breaking the spaghetti up into pieces before you put it into the crock-pot? Adding water won’t help because there should be more than enough liquid in the sauces. Make sure the sauce is covering the spaghetti . . . that might do the trick.

  9. Followed directions to a tee….noodles still hard at dinner time. Disappointed with a ruined family dinner. :(

    • I’m sorry your family dinner was ruined. I’ve made this dish dozens of times and never had a problem, so I’m thinking the issue with undercooked spaghetti might have something to do with the crock pot itself. Maybe your crock pot doesn’t heat the same as mine.

      UPDATE: I’ve revised the cooking time to 4-6 hours or until the spaghetti is tender. If you find your pasta isn’t soft after 4 hours, keep cooking and check on it periodically until it is. If that doesn’t work, pre-cooking the pasta until it’s al dente might do the trick. But this adds an extra step, and the 4-6 hour cook time would have to be adjusted.
