How to Cook the Crockpot Chicken Spaghetti Casserole: A Step-by-Step Guide

    Prep your chicken

    • Start by placing your chicken breasts in the bottom of the crockpot. No need to do anything fancy here—just throw them in!

    Add the creamy goodness

    • Pour the can of cream of chicken soup over the chicken. Add the sour cream (or Greek yogurt if you’re feeling fancy). This is where the creamy magic begins!

    Season it up

    • Sprinkle the garlic powder, onion powder, dried basil, salt, and pepper over everything. Don’t worry if you get a little extra—seasoning is your friend.

    Pour in the marinara

    • Now, pour the marinara sauce on top. Don’t be shy—let it coat everything nicely. This will give the dish its rich, Italian flavor.

    Add the chicken broth

    • Pour in the chicken broth (or water if that’s all you’ve got). This helps everything cook evenly and adds extra moisture.

    Set and forget

    • Cover the crockpot with the lid, set it to low, and let it cook for about 5 hours. If you're in a rush, set it to high for 3 hours. Your kitchen is going to start smelling amazing, so don’t say I didn’t warn you!

    Cook the pasta

    • About 30 minutes before your chicken is done, cook your spaghetti according to the package instructions. Drain and set it aside.

    Shred the chicken

    • Once the chicken is fully cooked (it should shred easily with a fork), pull it out and shred it right in the crockpot. Don’t be afraid to get a little messy—this is the fun part!

    Add the pasta and cheese

    • Toss your cooked spaghetti into the crockpot and mix it all together. Then, sprinkle the mozzarella and Parmesan cheese on top. Stir until everything is cheesy and bubbly. Don’t be afraid to sneak a bite... you’re going to love it!

    Serve and enjoy

    • Scoop out a hearty portion onto your plate, grab a fork, and dig in! You just made an amazing dinner with minimal effort. High five, you!

    Notes

    • Use rotisserie chicken for a quicker option.
    • Undercook the pasta slightly to avoid it becoming too soft.
    • Feel free to adjust the seasoning to your taste—more garlic, a pinch of red pepper flakes, or even some Italian herbs for extra flavor.
