Slow Cooker Spaghetti

Now I serve this spaghetti sauce over spaghetti squash, but you are more than welcome do to a pasta if you prefer.

Or if you are gluten-free spaghetti squash is a wonderful alternative, or reach for zoodles, or even gluten-free pasta.

Main Ingredients Needed

Meat Sauce | I made this homemade meat sauce in the slow cooker. Ground beef, tomatoes, a handful of seasonings!

Spaghetti Squash | Skip the pasta and reach for a spaghetti squash. I cooked in the microwave and transferred to oven for an easy pairing to the sauce.

How to Make Slow Cooker Spaghetti Sauce

Start by cooking your ground beef in a skillet, and then drain off the excess fat. Pour the meat into the slow cooker and add in your diced tomatoes, tomato sauce, and seasonings.

Stir and then cover and cook for 4 hours. Serve over pasta, zucchini noodles or even spaghetti squash like I did here.

How to Cook Spaghetti Squash

To cook your spaghetti squash in the microwave just clean your squash. Then cut holes in the squash and place on a plate. Cook on high for 8 minutes.

Slice squash in half, remove seeds, then you will want to place the squash halves on a baking sheet drizzled with olive oil. Then season with salt and pepper.

Accessories I Recommend for Slow Cooker Cooking

Disposable Liners | Liners are great so you can place in the slow cooker, then toss in food. Then you can keep your slow cooker clean, as your food bakes. Then when done, toss the disposable liner in trash and have minimal cleanup.

Meat Chopper | A great tool to use for any cooking of crumbled meat. Whether you do beef or sausage this works great at crumbling up your meat.

Bag Holders | If you make extra food and love to meal prep, use these bag holders to pour food in bags so easily. This is a must-have tool I use all the time in my kitchen.

Freeze Leftover Meat Sauce

You are more than welcome to freeze any leftover meat sauce you have on hand. You can freeze all in one container or do single servings if you want to pair with some noodles for a quick lunch.

Freeze your meat sauce for up to three months in the freezer. Do a sealable freezer bag or airtight freezer container.
