Here we are, friends. SEPTEMBER.

September around here means back to school, back to routine, back to eating dinner at home and fewer park picnics and camping weekends. But I love September.

Easy crockpot meals are always a big hit here, so I knew I had to bring you a few new ones to kick off the season. This Slow Cooker Baked Ziti and healthier Slow Cooker Spaghetti and Meat Sauce are others you might enjoy!

This Crockpot Chicken Spaghetti is a slow cooker spin on one of my favorite casseroles here on The Recipe Rebel — this Healthier Creamy Chicken Spaghetti. It’s a healther twist on the Pioneer Woman’s Chicken Spaghetti, made with a few extra veggies and no canned soups anywhere in sight.

Instead, I make the sauce with low fat milk and corn starch, after the chicken has simmered in the broth until tender (which gives this recipe so much flavour!). Then you add the spaghetti noodles right to the crockpot, which means that instead of boiling and draining, they’re soaking up all that awesome flavour we’ve been building.

Pretty cool, hey?

How to make this Crockpot Chicken Spaghetti:

The rules are optional. If you like different veggies, throw in different veggies. If you want to skip the chicken, go ahead. If you want to use cooked ground beef, do it. If you want to use different cheeses, amazing. Feel free to make your own rules as you go, but try to stick to the ratio of pasta/liquid/protein/veggies for best results.
I say this every time I post a slow cooker recipe, but you have to know your crockpot. They all cook differently, some hotter, some cooler. Smaller ones will heat more quickly, larger ones more slowly.
Don’t overcook your pasta. Pasta takes some time to cook in the slow cooker (about 15-20 minutes), but you will want to check it every 5 minutes or so after the first 10, just to be sure you take it off the heat once it’s done. No one likes mushy pasta!
This isn’t a crockpot meal you can leave to cook all day, but if you need to let it go longer while away from the kitchen, try adding in frozen chicken breasts and cooking for 6 hours on low before adding your spaghetti.
If you need to speed things up, you can chop up your chicken before adding to the slow cooker, and it will cook more quickly.
