“I just made this chicken dish and was excellent. Thanks for the recipe”

This southwestern pasta is a unique creation here at the magical slow cooker. The cool sour cream and Rotel sauce go amazingly with the pasta and chicken. It’s truly an excellent meal to come home to, for it’s almost ready to serve.

The Magic Ingredients
Here are the ingredients that make this recipe special! Find the full recipe in the recipe card.
- Ro-Tel Tomatoes – Brings bold flavor with diced tomatoes and green chiles.
- Mexicorn – Adds sweet crunch with corn and peppers in one can.
- Chicken Breasts – Tender, juicy, and the perfect protein base.
- Sharp Cheddar – Melts into the sauce for rich, cheesy goodness.
- Sour Cream – Adds rich creaminess and blends the Tex-Mex flavors.
Tips and Tricks
Don’t be tempted to throw the pasta in without cooking it first—the slow cooker doesn’t get hot enough to cook it properly, and you’ll end up with chalky, mushy noodles.
This pasta has medium heat as written, but if you want it spicier, add a diced jalapeño or poblano pepper.
For the best melting, use freshly shredded cheese from a block instead of pre-shredded.
Reader Suggestion: Stir in a can of drained black beans for extra protein.
Serving Suggestions
This dish is a star on its own. Here are a few ways to make it better:
- This shredded chicken dish pairs perfectly with a light Caesar salad. Pair with warm garlic bread or crusty rolls to soak up the delicious sauce.
- Garnish with chopped cilantro, fresh tomatoes, and sour cream.
- Often we just pile this pasta in bowls and eat alone! It’s a perfect rounded meal in one bowl!
