Slow Cooker Baked Spaghetti
Spaghetti is a favorite in my house. Well, a favorite of mine! I have odd ball kids that spaghetti is not their favorite, chicken nuggets are their favorite. What is a mom to do?
My good friend asked a good question the other day “can I cook spaghetti in the slow cooker?“And my answer was “hmmmm. I don’t know“.
So I decided to try and figure out a way to cook the noodles without making them mushy. I wanted to try and see if I could cook the noodles in the sauce and how long that would take.
My first attempt was seeing if I could cook the noodles in the sauce in the slow cooker. I put a jar of sauce in the slow cooker and then put in my spaghetti noodles, set the slow cooker to low and let it cook. And cook. And cook. After 8 hours, I tried the noodles and some where cooked (the ones that were in the sauce) and some were not. Some seemed too cooked and well this was a bust. I had to toss it.
Trial and error folks…trial and error!
Rethinking this process, I decided to cook my sauce in the slow cooker and then add in some noodles that were cooked, but not all the way (al dente).
In cooking, al dente describes pasta and vegetables, rice, or beans that are cooked to be firm to the bite. The etymology is Italian “to the tooth”. In contemporary Italian cooking, the term identifies the ideal consistency for pasta and involves a brief cooking time. Molto al dente is the culinary term for slightly under-cooked pasta. Under-cooking pasta is used in the first round of cooking when a pasta dish is going to be cooked twice. The culinary term “al forno” is used for pasta dishes that are cooked twice. Pasta that is cooked al dente has a lower glycemic index than pasta that is cooked soft. When cooking commercial pasta, the al dente phase occurs right after the white of the pasta center disappears.

I added my sauce in the slow cooker (along with some ground beef and spices), let it get hot and then added in my noodles. If you want to add in some chopped veggies, now would be the time to do this. Chopped green peppers, onions or mushrooms would be great in this dish. On top of the noodles (friend suggested this, different then the first friend), I added in small chunks of cream cheese. and let that cook. I gave it a quick stir and added in some mozzarella cheese (melted cheese is always good on spaghetti).
A couple hours total and after cooking some garlic cheese bread, I had dinner.
And it was delicious…seriously!
One final note: you can keep the baked spaghetti in the slow cooker after it is done cooking, turn the temperature down to WARM. The noodles will keep cooking. And if you leave it in there for over an hour on WARM, your noodles will start to get mushy. I would suggest taking the baked spaghetti out of the crock-pot and serving from a serving dish.
No one likes mushy noodles!

This recipe is confusing; in header it says cook 4 hours, then in the recipe, it says 2 with an additional 30 minutes..which is it?!
Thank you Judy for pointing out that mistake. I have fixed the recipe. The cooking time is 2.5 hours on LOW total cooking time.
Made this tonight and I was concerned with the sauce amount but it turned out great. I prepared the hamburger long before and refrigerated it, same with the spaghetti and drizzled olive oil on it. Cooked it in my instant pot on the slow cooker normal setting for a total of 3 hours doing all the steps as needed at their times in the process. This is a keeper, we had none left after giving about a third to my mom and uncle. I have half of my portion leftover for tomorrow, that’s it. It was amazingly good and the extra spices really gave it a nice pop that would have been missing without themh due to the cream cheese. I can’t be on my feet for long periods so prepping the meat and spaghetti a bit ahead of time made it easy to just pop in and do what I needed to do. Definitely use a bigf enough crock, the noodles nearly filled my 6 quart Instant pot when I dumped them in.
So glad you enjoyed the recipe Sarah!
Can this recipe be doubled.
It sounds delicious!
If you have a bigger slow cooker it should be okay to double the recipe. You don’t want your slow cooker to be filled more than 2/3 of the way up.
Once again this was amazing, changed it up a bit and used 48 ounces of sauce and 3/4 block of cream cheese with Italian sausage instead of ground beef. Used rigatoni and a five cheese blend and it was amazing. Think this is how we’ll make this every time now. It is so good, so creamy and so delicious. It didn’t make too much sauce either and thad amazing flavor as always.
Thank you Sarah for your nice review of this recipe including your additions and substitutions. I welcome that sort of thing, because sometimes you guys, the readers, make a recipe even better!
