Thanksgiving Casserole has all the flavors of that delicious holiday feast conveniently made in your slow cooker. Now there’s no reason to wait for the holiday season to enjoy Thanksgiving dinner when the craving strikes anytime of the year.

Why this recipe works

Who doesn’t enjoy Thanksgiving dinner? But who really loves doing all the dishes after making each side dish individually more than once a year? That’s where this recipe comes in.

Classic Thanksgiving table recipes meet comfort food in this multiple layered creamy casserole that features some of your favorites like green bean casserole, mashed potatoes (and sweet potatoes if you like), turkey (or in this case, chicken), and stuffing.

It’s really like all the traditional holiday favorites of sweet potato casserole, classic green bean casserole, cooked turkey (er, chicken), and a dressing recipe all rolled into one easy dish.

Once done, the potatoes will be fork tender and could easily be smashed like mashed potatoes. This is the ultimate in Thanksgiving casseroles, all the delicious food in one pot. Want to use ham? Try my Slow Cooker Christmas Casserole.

Recipe Ingredients

• Chicken — we used chicken breast, but a mixture of white and dark meat could be used. Turkey breasts or turkey tenderloin can be used IF you can find them at the store
• Potatoes — classic russet potatoes work best, but a mixture of those with sweet potatoes is delicious.
• Stuffing — turkey flavor Stove Top is our favorite, but chicken is also tasty.
• Green beans — we used frozen, but fresh trimmed greens are perfect too.
• Pantry staples — cream of mushroom soup, cream of chicken soup, French fried onions, salt, pepper, garlic powder, onion powder, and dried parsley.
• Dairy — butter, milk, and mozzarella cheese. We don’t recommend using pre-shredded cheese, the anti-caking agent used on the cheese can lead to a dryer casserole.

Step One – Our first layer is the potatoes. Peel and cube them into small pieces (sweet potatoes too if you’re using them.) Add them to the crockpot and pour the milk over, place the butter slices on top of the potatoes. Sprinkle with the allotted salt and pepper.

Step Two – For the second layer, cube the chicken and add it to a bowl. Toss the chicken with the salt, pepper, onion powder, garlic powder, and parsley. Stir the chicken until all the pieces are completely coated with the seasonings and then add it to the slow cooker over the potatoes.

Step Three – As evenly as possible, spread the cream of mushroom soup over the chicken completing the third layer.

Step Four – Sprinkle the stuffing packet over everything and place the remaining stick of butter slices on top.

Step Five – Cover the stuffing and butter with the green beans.

Step Six – Smooth the cream of chicken soup over the green beans as evenly as possible.

Step Seven – Cover the entire surface with the freshly grated mozzarella cheese.

Step Eight – Cover the slow cooker with its lid and cook on LOW for 6-7 hours. Cooking time will vary depending on your actual appliance but the edges should have begun to brown, the top bubbling, and the chicken has reached an internal temperature of 165°F. The potatoes should also be fork tender.

Step Nine – Once done, sprinkle the French fried onions over the top.

Tips:

• Place the French fried onion on a baking sheet and place under the broiler for a minute or two to warm, brown, and crisp before adding them to the casserole. This is not necessary but does add a nice touch. Or you can brown the french fried onion in a dry skillet.
• Before starting the layers, liberally spray the entire inner crock with cooking spray to avoid any possible sticking.
