This Slow Cooker Baked Spaghetti has a slow-simmered beef sauce layered with pasta with a cream cheese layer, and a mozzarella layer. It’s often called Million Dollar Spaghetti, whatever you choose to call it, it’s delicious.
You won’t want boring spaghetti ever again once trying this cozy casserole! It is a perfect weeknight dinner and good enough to serve to guests. We also make Ravioli Lasagna, and Classic Lasagna which have very similar to the flavors in this recipe!
What is the difference between normal spaghetti and baked spaghetti?
- Regular spaghetti has just noodles, meat, and sauce, and made on the stove top.
- Baked Spaghetti is spaghetti and sauce topped with a creamy cream cheese and ricotta mixture and topped with cheese, and baked to meld all the flavors together. In this case we are using our slow cooker to “bake” this casserole. Baked spaghetti tastes like an ultra decadent lasagana (but of course with different noodles).
Recipe Ingredients
- Pasta sauce – You can use Ragu, Newman’s Own, Rao’s or even make your own homemade marinara in this recipe! Just use two 24-oz. jars.
- Ground beef – Cook ground beef on the stove top with salt, pepper, basil, garlic and onion.
- Spaghetti noodles – One pound of cooked spaghetti noodles will be added to this after the sauce has simmer all day.
- Cream cheese mixture – Cream cheese, ricotta and salt make up the creamy layer in this million dollar spaghetti.
Step One – Add both jars of pasta sauce to the slow cooker.
Step Two – Cook the ground beef in a skillet on the stovetop, cook with the seasonings and onion, add the garlic the last few minutes of cooking. Drain the grease and add to the crockpot with the sauce.
Step Three – Stir the mixture and cook on LOW for 6 hours. WAIT TO ADD THE NOODLES AND CREAM CHEESE MIXTURE.
Step Four – Near the end of the cooking time cook the spaghetti noodles on the stovetop. I cook mine for 8 minutes exactly, slightly undercooking them for they will cook a little more when we assemble the casserole. Drain the noodles and add them to the cooked sauce.
Step Five – Stir the noodles into the sauce and slightly press the noodles into an even layer (like you would for a casserole).
Step Six – In a small bowl, combine the cream cheese, ricotta, and salt. Add this mixture on top of the noodles and sauce in dollops.
Step Seven – Spread the dollops out evenly over the pasta.
Step Eight – Sprinkle over the mozzarella cheese. Place the lid back on the slow cooker and cook for an additional 20 minutes on LOW.
Step Nine – Turn the slow cooker off so the dish doesn’t overcook. Serve and enjoy!
What to serve with this:
- Garlic bread or breadsticks
- Roasted Broccoli or Brussel Sprouts
- Fresh green salad and dressing
Recipe FAQs
No, the slow cooker doesn’t get hot enough to cook pasta properly, instead of cooking properly it turns into a chalky mess.
Spaghetti or linquine noodles are best for this recipe. You can use penne or rigatoni if desired. I do not recommend angel hair noodles or egg noodles for they are not the right texture for this dish.
Some do not like ricotta. You can use more cream cheese instead or use cottage cheese and you’ll still have a wonderful meal.
Yes, this recipe freezes well. Place the leftovers in freezer-safe containers or freezer ziplock bags. Freeze for up to three months.
Yes! Though slow cooking the sauce really makes the dish, you can do this in the oven instead. Add your sauce to the cooked meat and pour over the spaghetti in a 9×13 pan. Add the creamy mixture and mozzarella cheese. Bake at 375°F for 30 minutes, uncovered.
Ground Turkey – For a healthier version of baked spaghetti use ground turkey. You may want to add extra seasonings for more flavor.
Ground Italian Sausage – For more Italian flavor, cook and crumble Italian sausage instead, you can use sweet or spicy.
Soy Crumbles – Looking for a vegetarian version? Just add bagged soy crumbles instead of the beef.

Slow Cooker Baked Spaghetti
Ingredients:
- 48 oz. Pasta Sauce Such as Ragu Old World Style, Newman's own Marinara, or Rao's Marinara.
- 1 1/2 lbs. ground beef
- 1/2 cup diced white onion
- 1 minced garlic clove
- 1/4 tsp. salt
- 1/4 tsp. black pepper
- 1 tsp. dried oregano
- 1 tsp. dried basil
- 1 lb. spaghetti noodles see below for cooking instructions, these don’t get cooked or added until after the sauce cooks for 6 hours
Cheese topping after sauce cooks:
- 4 ounces cream cheese 1/2 cup
- 1 cup ricotta cheese
- 1/4 tsp. salt
- 2 cups shredded mozzarella cheese
Instructions:
- Pour the jars of sauce in to the slow cooker. In a large skillet set over medium-high heat, brown the meat and onions together. After the meat is browned add the garlic, cook for a minute a longer. Drain the fat. Add the salt, pepper, oregano and basil and stir. Pour the meat onto the sauce in the slow cooker and stir.
- Cover and cook on LOW for 6 hours without opening the lid during the cooking time.
- After the cooking time is up, cook the noodles as directed on the package in boiling water on the stove-top. I cooked my noodles for exactly 8 minutes after adding them to the boiling water. The noodles will cook a bit more after adding them to the slow cooker.
- Drain the noodles and add them to the meat sauce in the slow cooker. Stir, then flatten the noodles in an even layer.
- In a small bowl combine the cream cheese, ricotta and salt. The cream cheese will be in small chunks, but that is fine.
- Dollop the cream cheese/ricotta mixture over the spaghetti, then use a spatula to even it out over the spaghetti. Add the mozzarella cheese.
- Cover and cook for an extra 20 minutes on LOW.
- Serve and enjoy!

Thank you it was a hit last night. My son doesn’t come often so when he does I like to make it special. He told me he was in the mood for spaghetti with meat balls. I asked if he would opt for spaghetti with ground beef instead and he agreed. I made it and him and my little ones are it all up… I loved it myself. My husband wasn’t a fan but he is not a cheese lover. So WHATEVER… lol
Anyhow thank you for sharing and making our night special because my son absolutely loved it.

Just mixed the meat in the sauce
The anticipation is killing me there is no doubt it will come out delicious
Judi says
Has anyone tried it with ground turkey instead of beef? Thanks.
Anonymous says
Yes it comes out delicious!

While I liked this recipe, the prep work is the same as regular spaghetti and would have been easier to just do the prep and bake it in the oven. Pre cooking everything kind of ruined the whole crock pot idea. It was a very good meal but just think easier doing it in the oven.

Flavors are enhanced with the slow cooking! More economical to use the slow cooker than to use your big oven!
Sally says
I browned twice the meat and froze it in a zip lock bag with the sauce and seasoning (plus mushroom and olive) now I can just thaw it out and heat it in the crock pot on a busy weeknight :).

Can you make another mixture with just mozerella cheese and cream cheese somehow? I’m stuck st home for the weekend and don’t have ricotta at the moment. I can’t wait to try this thank u
Sarah Olson says
Yes, I think that will work fine!
Ashley Allred says
Hi! I’m SO excited to try this! I only have 1 pound of hamburger meat. I was thinking maybe trying to just use 1 and a half jars of sauce but still cooking for the full time? Do you think that would be okay?
Sarah Olson says
I think it should be fine!
Joleen Ann Jorge says
I made this recipe for an Italian themed luncheon at the school where I work Teachers are generally very good cooks and these meals are always wonderful. Everyone asked for the recipe! That’s a big 5 stars!!!! Thanks for all your recipes. I haven’t tried anything that wasn’t delicious
Sarah Olson says
Happy to hear that Joleen, this recipe is one of my favorites. Makes so much and the leftovers heat up great.
Vicki says
How do you suggest reheating?
Sarah Olson says
We heat in the microwave. Sorry I don’t have a fancier answer!
Vicki Kolstad says
Thanks! I am not fancy either! I am going to try putting it on the warm setting on the Crock-Pot but, if not hot enough, will also use microwave!
Amber says
Thinking of freezing half of it. How long would I need to cook it in the oven after it defrosts?
Sarah Olson says
I’m unsure. I’m guessing 30 minutes.
Robert Tyler Thompson says
I rolled this in a flour mixture and deep fried it.
Sarah Olson says
Awesome! I bet that was great.
ushealthjournal says
I will try to make this recipe for my son today. I hope he will like it.
Emilie says
What would you suggest doing if you wanted to make this a freezer meal? Thanks for the help!
Sarah Olson says
Just do the sauce and meat in a baggie. Then add everything else after cooking.
Erika says
I have a 4-quart crock-pot not a 6-quart….how would you reduce the recipe so it would fit?
Angie says
Is it possible to cook it on high for 3 hours instead? I want to make it tomorrow but I forgot to buy the sauce tonight and will purchase tomorrow. I hope you get back to me in time!
Sarah Olson says
Yes I think that would be just fine!
