Why You’ll Love This Recipe

This dish is the definition of hands-off comfort food. With just three main ingredients, it is budget-friendly, forgiving, and perfect for busy days when you want something warm without a lot of work.

Ingredients

12 ounces rotini pasta, uncooked
4 cups low-sodium chicken or vegetable broth
2 cups shredded pepper jack cheese, divided
1 cup heavy cream or whole milk

Salt, black pepper, and garlic powder are considered free pantry staples and can be added to taste. Optional: shredded chicken, sautéed mushrooms, or diced jalapeños.

Directions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Spread the uncooked rotini evenly in the prepared baking dish.
Pour the broth and heavy cream over the pasta. Stir in 1 cup of the pepper jack cheese and season with salt, pepper, and garlic powder.
Cover tightly with aluminum foil and bake for 35 minutes.
Remove the foil and stir the pasta gently. Sprinkle the remaining 1 cup of pepper jack over the top.
Bake uncovered for another 10 to 15 minutes, until the pasta is tender and the cheese is melted and bubbly.
For extra color, broil for 1 to 2 minutes, watching closely to prevent burning.
Let rest for 5 minutes before serving.

Variations

Chicken Pepper Jack Rotini: Add 2 cups shredded cooked chicken before baking.
Spicy Lazy Rotini: Add diced jalapeños or red pepper flakes.
Vegetable Boost: Stir in sautéed mushrooms, spinach, or bell peppers.
Mild Version: Use Monterey Jack or cheddar instead of pepper jack.
Creamy Tomato Version:Substitute 1 cup of the broth with marinara sauce.
Gluten-Free: Use gluten-free rotini and adjust the baking time as needed.

Expert Tips

Do not overcook the pasta. It will continue to soften as it bakes.
Use freshly shredded pepper jack for the creamiest melt.
Stir halfway through baking so the pasta cooks evenly.
Add a splash more broth if the pasta looks dry before the final bake.
Let the casserole rest before serving so the sauce thickens and the portions hold together.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or in a 350°F oven with a splash of milk or broth to loosen the sauce. This dish does not freeze well because the creamy sauce can separate upon thawing.
