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 lasagna (but of course with different noodles). – We also love to make Crockpot Lasagna and Ravioli Lasagna.
Recipe Ingredients
- Pasta sauce – You can use Ragu, Newman’s Own, Rao’s or even make your own homemade crockpot marinara sauce. 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 simmered all day.
- Cream cheese mixture – Cream cheese, ricotta and salt make up the creamy layer in this million dollar spaghetti.

How to make Crockpot Baked 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!
Variations
- Spaghetti or linguine 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.
- For a healthier baked spaghetti, use ground turkey and add extra seasonings for flavor. For a more Italian taste, swap in sweet or spicy crumbled Italian sausage.
- For a vegetarian option, use bagged soy crumbles instead of beef.
- Swirl in a few tablespoons of pesto for added basil flavor.
My Serving Ideas
- Garlic bread, focaccia, or breadsticks.
- Roasted Broccoli or Brussels sprouts.
- Fresh green salad and dressing.
- Top with Parmesan cheese or red pepper flakes.
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.
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.

Reader Reviews
“My whole picky family loved this! It was easy to make and tasted yummy!” – Jayla
“This recipe, exactly as written, is AMAZING!! The only thing I did was add green and red bell peppers to the ground beef mixture. Tastes like it came out of the actual oven. I paired with a glass of red wine and Rhodes parker house rolls. Perfect for a Wednesday night with minimal effort.” – Eric

How to Video
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!

I do not use jarred sauce for spaghetti. Could I use my recipe and just make it in the crockpot and then add the other ingredients? I use beef and Italian sausages.
Yes, that would work great!
Thank you! I look forward to making it!
Does it hurt to cook the meat and sauce on low for longer than 6 hours? Will it overcook? I’m hoping to be able to put this on before work and come home and finish it. Thanks!
You can do 8 hours on low (my crockpot spaghetti sauce uses that time).
We have been using this recipe for years! It’s always a hit. Letting the sauce cook for 6 hours really binds the flavors. If you do not want to wait that long you don’t have to.
I suggest that once the meal is finished, do not keep it on the warm setting or it will continue to cook. It will stay warm on its own for quite some time.
It reheats very well. You can reheat it in the microwave or oven with a cover to keep steam in.
You can play with the ingredients in the sauce. Add mushrooms for example.
May I use glutenfree noodles. Will that change cooking time? They are spaghetti noodles
You can use whatever noodles you want!
Can I leave out the meat altogether ?
Yes you can.
Easy, no fuss version of spaghetti or million dollar spaghetti! Love crock pot recipes like this that you prepare hours before dinner, letting you do something else the rest of the afternoon and you don’t have to stop what you’re doing to get dinner! No stress! And everyone loves spaghetti and meat sauce! Even a WASP like me!
Gonna try this
I made this for a Saturday night supper. Another five star recipe and will make again. As stated in your comments, not all jarred sauces are created equal. Mine was a bit low on seasoning (not one of the suggested) and I did have to add extra oregano, onion, and garlic. Next time, I will use my own marinara sauce to better control the flavor. But, yummy either way. Slow cooking makes the difference, for sure. Oh, and it does serve 8. We’ll get several meals out of it. Looking forward to making another one of your slow cooker recipes. They are the best!
Can I add sour cream to this or do you think it will change the flavor ?
You can add a little. Too much will make it too liquidy.
I added some sour cream to mine ( I didn’t have ricotta). I use the squeeze bottle so I did like 5 squirts. I did at the same time as the cream cheese and spread it along with the cream cheese. Doesn’t really change the flavor much but gave it another slight layer of flavor.
I make this a lot. It always comes out great. I use RAGU Chunky with onions, basil, and garlic for the sauce. I also use Whole Grain spaghetti noodles because my husband is diabetic. This recipe doesn’t bother his sugar at all. I make it for our church Bible Study and everyone loves it.
