How to make jalapeno popper chicken casserole step by step

The method has six steps. Each step ends with a result you can check.

Heat the oven and boil the pasta

Preheat the oven to 375°F and grease a 9 by 13 inch baking dish. Boil the macaroni for 1 minute less than the package directions. It should feel firm in the center, since it finishes in the oven. Drain it well.

Mix the creamy base

Stir the cream cheese, sour cream, mayonnaise, milk, garlic powder, salt, and pepper in a large bowl. The base looks smooth with no cream cheese lumps.

Fold in the chicken, pasta, and add-ins

Add the chicken, pasta, 1 cup of cheddar, half the bacon, the diced jalapenos, and half the green onions. Stir until every piece looks coated.

Fill the dish and add the topping

Spread the mixture into the dish. Top it with the remaining 1 cup of cheddar, the rest of the bacon, and the jalapeno slices.

Bake until bubbly

Bake for 20 to 25 minutes. The casserole is done when the cheese looks melted and the edges bubble.

Rest and serve

Let the dish rest for 5 minutes, then top it with the remaining green onions. Resting helps the sauce set, so each scoop holds together.

Common mistakes and quick fixes

Each fix ties back to a result in the steps.

A soupy casserole usually means the pasta was overcooked or not drained well. Pull it a minute early and drain it fully.

When the dish tastes too hot, seed the jalapenos next time.

A dry top means it baked too long. Take it out as soon as the cheese bubbles.

Serving ideas

Serve a scoop with a side of Tomato Garlic Salad to cut through the creamy sauce.

Fans of cheesy pasta can also pair it with Creamy White Cheddar Pasta for a comfort food night.

For game day, serve it in small bowls with tortilla chips for scooping.

Storing and reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Here is how to reheat it. Cover the dish with foil and warm it at 350°F for 15 to 20 minutes, until hot in the center.

You can freeze it for up to 2 months in a freezer-safe container. The texture may soften after thawing, so thaw it in the refrigerator first.

Common questions

Can I use rotisserie chicken?

Yes, shred about 3 cups of cooked rotisserie chicken. It saves time and adds flavor.

How do I make it less spicy?

Remove the seeds and white ribs from the jalapenos before dicing them.

Can I make it ahead?

Yes, assemble the dish, cover it, and refrigerate it until you bake it. Add a few extra minutes to the baking time if it goes in cold.

What pasta works best?

Elbow macaroni holds the sauce well. Rotini or shells also work.
