Ingredients
- Boneless skinless chicken breast or thigh meat: Juicy tender bites that make this a heartier meal Look for fresh chicken with no added water for best texture
- Bacon: Smoky crispy bits that add tons of flavor Use thick-cut for extra chew and buy it in slabs to dice yourself
- Rotini pasta: Twirls hold the sauce beautifully Pick a sturdy brand so the noodles do not become mushy
- Cream cheese: Softened for creaminess and tang Choose blocks over tubs for richer taste
- Sour cream: Adds extra creaminess and a subtle tang Go for full-fat varieties for silkier texture
- Milk: Thins the sauce so it coats everything evenly Any milk works but whole milk gives the richest casserole
- Mexican Cheddar Jack Shredded Cheese: Melty and flavorful Look for cheese that is not pre-shredded if possible so it melts smoother
- Jalapeno peppers: Provides signature heat and bite Choose bright green firm peppers and control heat by removing seeds
- Green onions: Fresh snap and pop of color Slice them thin to distribute flavor
Step-by-Step Instructions
- Prepare the Casserole Dish:
- Grease a twelve by nine inch casserole pan with butter or nonstick spray Make sure it is well coated to prevent sticking and for easier cleanup
- Cook the Pasta:
- Bring a large pot of salted water to a boil and cook the rotini according to its package until just al dente Drain well and do not overcook to avoid soggy casserole
- Cook Chicken and Bacon:
- While pasta cooks cut both chicken and bacon into bite-sized pieces Place both in a large skillet over medium heat stirring often Cook until chicken is no longer pink and bacon is crisp Use a slotted spoon to remove onto a paper towel lined plate to remove extra fat
- Prepare Vegetables and Sauce:
- Dice the jalapenos removing seeds for less heat and thinly slice the green onions Leave a little onion for topping In a mixing bowl combine softened cream cheese sour cream milk one and a half cups of shredded cheese diced jalapenos and most of the green onions Mix thoroughly
- Assemble the Casserole:
- Place drained pasta in the prepared baking dish Scatter cooked chicken and bacon over the pasta reserving a bit of bacon for topping Spoon the creamy jalapeno mixture evenly across the casserole Gently stir everything together so pasta is well coated

- Sprinkle remaining shredded cheese over the top Add the reserved bacon more green onions and a few jalapeno slices for extra punch
- Bake:
- Place in a preheated oven at three hundred fifty degrees and bake for twenty minutes until hot and bubbly The cheese should be melted and golden around the edges

My favorite ingredient is the fresh jalapeno The way it wakes up the whole dish reminds me of cooking with my grandma who loved sneaking spicy touches into weeknight dinners Everyone always guessed her secret was "magic" but now I know it was simply fresh jalapeno.
