I’ve had a hankering for spaghetti for a while now. Since I had so much success making marinara sauce in the slow cooker, I decided to try it again, this time using sweet Italian chicken sausage from the freezer.
This slow cooker sausage spaghetti sauce can be changed any number of ways.

It’s really hard to make a bad pot of spaghetti sauce and mine rarely turns out the same way twice. Which is fine since I’m not cooking for a restaurant ๐
This makes a big batch – perfect for feeding a crowd or freezing in smaller portions for future quick and easy meals.
I shared this slow cooker spaghetti meat sauce with Mom, my brother, and my neighbor, Pat. Everyone gave it hearty praise.

I served mine the traditional way, with spaghetti, but you could of course, substitute any shape pasta, spaghetti squash or even zucchini noodles, if you are so inclined.
A combination of spaghetti and spaghetti squash is really satisfying too. Enjoy!

Slow Cooker Sausage Spaghetti Sauce Recipe
Ingredients
- 2 pounds sweet Italian Chicken sausage (Substitute turkey sausage if it's easier to find)
- 1/2 cup chopped onion (optional)
- 1/2 bell pepper, chopped (optional)

- 1 teaspoon dried basil
Instructions
- Ideal slow cooker size: 5- to 6-Quart. (I used my InstantPot.)
- Cook the chicken sausage in a large skillet (affiliate link) set over medium heat, until crumbled and slightly browned.
- Add the garlic, onion and bell pepper if using and cook, stirring often, 3 to 4 minutes or until the onion softens slightly.
- Scrape the sausage mixture into the slow cooker.
- Add the tomatoes, tomato paste, sugar and seasonings. Stir to combine. (My crushed tomatoes were really thick, so I also added 1 cup of water.)

Here’s another easy recipe for meat-lover’s slow cooker spaghetti sauce from All Recipes that looks delicious. Though the Points are sure to be higher since it calls for both ground beef and Italian pork sausage, it provides a nice visual look at the steps involved in making meat-based spaghetti sauce in your slow cooker:





This sauce is fantastic. Extremely flavorful and satisfying. I put it over spaghetti squash strands and had a fabulous lunch for 2 points. Yes, 2 points!!
I’m looking for chicken sausage too. Please suggest where we can purchase or make our own? I’ve ground chicken breast before to make another recipe so could potentially make my own chicken sausage. Just use the seasonings you’d use for beef/pork Italian sausage?
Hi Susie, You could substitute turkey sausage if it’s easier to find. Or make your own. If you google, “make your own Italian Chicken Sausage” lots of results come back from which to choose. ~Martha
HI THERE, I AM TOTALLY AT A LOSS WITH THESE MEASURES OF 1.05 LBS. OR 0.52 TSP. OF A HERB. HOW DO I CALCULATE THESE OVER TO TSP. OR TBSP ETC. THANK YOU. LOVE YOUR HELP.
Hi Christa, The recipe card allows you to adjust servings up and down. When not set to the default number of servings, the ingredient amounts are shown in decimal percentages. Click the servings up/down until you see standard measurement amounts. Hope this helps. ~Martha
Where can I find chicken Italian sausage? A brand name might help too.
Thanks, I’ve been missing spaghetti in my diet
I just got an Instant Pot, you said you made this in the instant pot, could you publish directions for that as well.
Hi Barb,
I cooked it in my Instant Pot but with the slow cooker settings not as a pressure cooker. – Martha

Hi Robyn,
Yes, it’s a different recipe. Sorry for the confusion.

What do you mean by “Chicken Sausage from the freezer”? Can you tell me the name brand you use? I’m assuming it needs to be defrosted before you fry it up, correct?
