Ingredients

Meatballs: Frozen Italian meatballs are easy, taste great, and work beautifully in this Italian crockpot recipe!
Pasta Sauce: We’re using a jar of store-bought pasta sauce (your choice!) and cans of diced tomatoes to make this simple sauce.
Pasta: Spaghetti noodles, cooked to al dente, will combine with the sauce, cheese, and meatballs for the most scrumptious spaghetti you’ve ever swirled on a spoon!
Cheese: The trifecta of dairy deliciousness – part-skim ricotta, shredded parmesan, and shredded mozzarella – brings all the luscious cheesy goodness to make this recipe stand out!
Seasoning: Basil, oregano, and garlic salt seriously “up” the Italian flavors in this dish!
How to Make Slow Cooker Cheesy Spaghetti
STEP ONE: Put the frozen Italian meatballs, spaghetti sauce and diced tomatoes into the crockpot and stir to combine. Cover the slow cooker and set on LOW for 6 hours.


STEP TWO: When the meatballs are almost done cooking, bring a large pot of salted water to a boil. Cook the spaghetti to al dente, drain the water, and add the pasta to the slow cooker. Stir gently to mix the noodles in with the meatballs and sauce.

STEP THREE: In a small bowl, combine the ricotta and Parmesan with the basil, oregano, and garlic salt. Spoon this mixture into the crockpot over the top of the spaghetti and meatballs, then cover with the shredded mozzarella.


STEP FOUR: Replace the lid and set the slow cooker to cook for an additional 20-30 minutes to melt the mozzarella cheese fully. Serve with garlic bread and a side salad for the perfect easy Italian dinner! Enjoy!

Tips for Success
- Simply substitute g-f pasta to make this entire dish gluten-free!
- Leave out the meatballs and add some diced vegetables for a great vegetarian recipe.
- The pasta can be cooked IN the crockpot, along with everything else, but add about 3/4 cup of water into the mix.
- If you cook the pasta separately, according to the recipe, it freezes much better.
- Grated cheese works fine, and it’s fast, but shredding your cheese only takes a minute, and you avoid all that cellulose. Plus, block cheese melts smoothly and creamily.
- Use your favorite brand of spaghetti sauce for this recipe.
- A small can of tomato paste adds a nice, subtle sweetness.

Can You Put Dry Pasta in the Crock Pot?
Uncooked spaghetti noodles will cook just fine in the crockpot if you include enough liquid in your recipe. About ¾ cup of additional sauce, beef broth, or water (in addition to the other recipe ingredients) works well. It’s best to put a layer of sauce on the bottom of the slow cooker, then add the noodles and meatballs, then cover with another layer of sauce. The pasta will absorb all the flavors of the sauce. They will turn out a little softer than if you boil them to al dente, but it’s delicious and comforting, and cuts down on cleanup!

What’s the Best Way to Store Leftover Spaghetti?
To store in the fridge, simply transfer the Cheesy Spaghetti and Meatballs to a storage container and seal. Spaghetti will keep in the refrigerator for about 4 days—reheat in the microwave on 50% power.
If you have leftover sauce & meatballs (without the pasta), place them in a freezer-safe container, seal airtight, and freeze the sauce for up to 3 months. Allow to thaw overnight in the fridge before reheating. We don’t recommend freezing leftover pasta as it becomes mushy and falls apart when reheating. It’s better just to make fresh noodles when the sauce is reheated.

Lita Watson says
The color of your dish looks so amazing! Can i set the slow cooker on high to cooked this dish? How long will it take to finish?
Julie @Real Housemoms says
Hi Lita. Changing from LOW to HIGH temp on the slow cooker usually halves the cooking time. So you’d be looking at about 2-3 hours. That being said this dish better at the lower temp so nothing overcooks or burns along the edges.
