Ingredients Needed

• Pasta:  dried rotini pasta about 3 cups
• Dairy: Butter, half and half, and shredded cheese like Pepper Jack and cheddar cheese.
• Vegetables: Red bell pepper, diced onion, corn, canned green chiles, and green onions for garnish.
• All purpose flour: Helps to thicken the sauce.
• Chicken stock: Low sodium
• Herbs and spices: Salt, black pepper, paprika, and taco seasoning 
• Chicken: diced cooked chicken. This is an easy way to use leftover chicken from another meal or use rotisserie chicken.
• Chips: Crushed Fritos corn chips

• Step 1: Heat an oven-safe skillet and melt your butter. Add red peppers and onions to the skillet and cook until soft. 
• Step 2: Whisk in flour and cook a few minutes in the large skillet. 

• Step 3: Next, whisk in chicken stock with your half and half and bring to a low simmer to thicken. 
• Step 4: Add salt, pepper, paprika, and taco seasoning. Whisk to combine. 
• Step 5: Add cooked pasta, chicken, corn, green chiles, and shredded cheese and fold to combine together.
• Step 6: Sprinkle with crushed chips on as the top layers before baking.

Recipe Tips

• When cooking pasta for this Tex-mex casserole, be sure to cook to al dente as it will continue to cook a bit more in the oven.
• In addition to the green onions, you can garnish each serving with a dollop of sour cream. 
• No Fritos? Try crushing up tortilla chips instead.  
• The best part is the leftovers taste just as good the next day! Be sure to transfer leftovers to an airtight container and refrigerate for up to 2-3 days. The chips may start to turn soggy over time. 
• For the ultimate Tex-Mex experience, serve this casserole with some homemade tortilla chips and homemade Fire Roasted Salsa– it will quickly become a new family favorite meal to add to your weekly meal plan rotation, especially on Taco Tuesdays!
