If you’re in the mood for something cheesy, creamy, and spicy, look no further than this jalapeño popper chicken pasta casserole. The decadent dish is an irresistible combination of tender pasta mixed with chicken, crisp bacon, melted cheese, and so much flavor.

Jalapeño Popper Chicken Pasta Casserole Ingredients

You’ll need:
- 2 (8-ounce) packages of cream cheese, softened
- ½ cup of mayonnaise
- ½ cup of sour cream
- ½ teaspoon of onion powder
- ½ teaspoon of garlic powder
- ½ teaspoon of salt
- ½ teaspoon of pepper
- 7.4-ounce jar of diced, pickled jalapeño peppers, drained
- 2 cups of milk
- 2 cups of grated jack cheese, divided in half
- 2 cups of grated cheddar cheese, divided in half
- 1 pound of rotini pasta, cooked and drained
- 3 cups of chopped rotisserie chicken meat
- 3 green onions: white and green parts separated, green parts sliced, and white parts diced
- 1 pound of bacon, cooked and crumbled
- Fresh jalapeños for garnish (I used 1 whole)
PRO TIP:
Be sure NOT to use pre-shredded cheeses. They have additives added in the bags to prevent clumping, and they do not melt as well as a block of cheese that you shred yourself.
Substitutions And Additions
SOUR CREAM: Using a combination of sour cream and mayonnaise in the filling gives a nice balance of richness and light creaminess. You can substitute all sour cream if preferred in this easy casserole.
JALAPEÑOS: Using diced, pickled jalapeños is both extremely convenient and also infuses more of that delicious jalapeño flavor into the dish. You can substitute 3 freshly diced jalapeño peppers. Remove the seeds and ribs for a milder dish.
CHICKEN: Rotisserie chicken makes this dish easy to make, but if you have leftover cooked chicken breasts or chicken thighs, you could chop them up and use them instead.
How To Make This Jalapeño Popper Chicken Pasta Casserole Recipe
OUR RECIPE DEVELOPER SAYS
Cook the pasta to al dente in boiling, salted water to season the pasta before it goes into the casserole. We will not add additional salt to the casserole itself.
STEP ONE: Preheat the oven to 350°F.
STEP TWO: In a medium bowl, combine the cream cheese, mayonnaise, sour cream, onion powder, garlic powder, salt and pepper, and diced jalapeños. Use a hand mixer for quick blending. Continue mixing while gradually adding the milk.
PRO TIP:
Use gloves when handling the jalapeños. Otherwise, the heat from the oils will be left on your skin and can irritate your skin, not to mention if you touch your face or eyes.

STEP THREE: Add 1 cup each of cheddar and jack cheeses and stir to combine.

STEP FOUR: In a large mixing bowl, toss together pasta, chicken, the white part of the green onions, and most of the bacon, reserving about ½ cup to sprinkle over the top.

STEP FIVE: Add the cream cheese mixture to the pasta mixture and stir gently until the mixture is evenly combined.

STEP SIX: Spread the casserole filling into a 9×13-inch casserole dish.
STEP SEVEN: Top with remaining shredded cheese. Sprinkle the reserved bacon and fresh jalapeño slices over the cheese.

STEP EIGHT: Bake for 20 minutes until the cheese is melted. Remove from the oven and top with freshly sliced green onion. Serve hot.
PRO TIP:
Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your casserole as the suggested baking time approaches.

Gini Johnson says
can you use fresh jalapenos instead?
Layne Kangas says
Hi, Gini – we like the flavor the pickled jalapenos give in the dish, but you could probably swap out for all fresh. I’m not sure how that would impact the heat level as we haven’t tried it. Enjoy!
Deborah Gillis says
I used fresh peppers and loved the crunchness of them but it’s still burning my mouth. LOL! And yes I did take out the seeds. Thank you for the recipe.
