This crockpot King Ranch chicken soup is my answer to busy weeknights when everyone wants bold flavor and creamy comfort with nearly zero effort. Inspired by Texas’ iconic King Ranch chicken casserole, this cozy soup tosses tender chicken, zesty tomatoes, chilies, and Tex-Mex spices into your slow cooker for a meal that practically makes itself. With a quick swirl of cream cheese at the end, it becomes even richer and more satisfying.
I whipped this up one cold Sunday when we needed a warm-up after soccer, and by dinnertime the whole house smelled incredible. Now my family asks for it whenever the weather gets chilly.
Ingredients
- Butter: adds an essential richness and subtle flavor that you do not want to skip
- Onion: choose a small yellow onion for mellow sweetness or any variety you have on hand
- Garlic: fresh cloves give the best kick but jarred or powdered work when time is tight
- Bell pepper: red is sweeter but green or yellow add crunch and color
- Rotel tomatoes with chilies: are the secret to that signature Tex-Mex bite look for mild if cooking for kids
- Cream of mushroom soup: brings a velvety creaminess and helps thicken the broth no homemade roux needed
- Shredded chicken: rotisserie or leftover chicken saves time and adds hearty protein aim for juicy and not overcooked
- Chicken broth or veggie broth: forms the flavor backbone use a low sodium version for more control
- Cumin: delivers classic earthy Tex-Mex aroma try freshly ground for the most fragrance
- Chili powder: brightens the soup with a bold warm flavor choose sweet mild or hot to suit your taste
- Cream cheese: cut into cubes and softened to give a tangy smooth finish let it come to room temp for easy melting
- Optional toppings: shredded cheese fresh cilantro crunchy tortilla chips all add color and extra flavor
Step-by-Step Instructions
- Prepare the Main Soup Mix:
- Add the butter diced onion minced garlic bell pepper Rotel tomatoes cream of mushroom soup shredded chicken broth cumin and chili powder to your crockpot insert. Stir gently to combine everything. The mixture will look chunky but it will smooth out as it cooks and the vegetables soften.
- Slow Cook Until Tender:
- Set your slow cooker to HIGH and cook for two hours or set to LOW for four hours. Do not lift the lid during cooking as this can let heat escape. During this time the vegetables soften flavors meld and the broth thickens slightly.
- Add Cream Cheese and Stir:
- Once the main soup base is hot and bubbling add the cubed cream cheese directly into the crockpot. Gently stir until the cream cheese has completely melted and combined into the soup. This step is important for a smooth creamy finish. Taste and adjust salt or spice if needed.
- Serve and Top:
- Ladle the soup into bowls and top generously with grated cheese fresh cilantro and crunchy tortilla chips. Add other toppings like pico de gallo or jalapeños for extra zip. Serve hot for best flavor and texture.

My favorite part is stirring in the cream cheese at the end and watching the broth turn silky and rich. The first time I served this at a family birthday my niece had three helpings which made me smile for days.
Best Ways to Store Leftovers
Let your soup cool to just warm before transferring to storage containers. Refrigerate for up to five days or freeze in portions for up to three months. I like to freeze in individual servings so I can thaw only what I need. Reheat gently on the stovetop over low heat to prevent separation.
Simple Ingredient Swaps
No rotisserie chicken on hand Use cooked turkey or even shredded pork for a twist. If you want a vegetarian version go heavy on mushrooms and add in chopped spinach or cauliflower. For a fresher taste or to reduce sodium swap in homemade salsa for the Rotel.
How To Serve This Soup
Set out a topping bar so everyone can customize their bowl. Think chopped cilantro sliced jalapeños shredded cheese and tortilla strips. I love pairing this soup with a crisp green salad or a dollop of guacamole on the side for extra color and freshness.

King Ranch chicken is a staple of Southern potlucks and is said to be named after the enormous King Ranch in Texas.
