Why This Recipe Slaps

In-text image 1

This casserole is the MVP of weeknight dinners. Zero pre-cooking means you literally dump ingredients in a dish and let the oven do the work.

The pasta cooks in the sauce, the chicken stays juicy, and the cheese? Perfectly melted. It’s like traditional Chicken Parm got a PhD in efficiency.

Plus, it’s customizable—swap ingredients, adjust spice levels, or double it for leftovers. Dinner wins, minimal effort.

Ingredients (Because You Can’t Wing It)

  • 2 cups uncooked penne pasta (or any short pasta—rigatoni works too)
  • 1.5 lbs boneless, skinless chicken breasts, cubed (because no one wants to wrestle bones)
  • 24 oz marinara sauce (store-bought or homemade—we won’t judge)
  • 1 cup water (yes, this is the pasta’s spa day)
  • 1 cup shredded mozzarella (the more, the merrier)
  • 1/2 cup grated Parmesan (the salty, nutty hero)
  • 1 tsp garlic powder (because flavor)
  • 1 tsp Italian seasoning (or just throw in some dried basil and oregano)
  • 1/2 tsp salt (unless you’re into bland food, then skip it)
  • 1/2 tsp black pepper (optional, but highly recommended)
  • 1/2 cup breadcrumbs (for that crispy top—trust us)
  • 2 tbsp olive oil (or melted butter, because why not?)

Step-by-Step Instructions (AKA How to Be a Kitchen Hero)

  1. Preheat your oven to 375°F. This isn’t a suggestion—unless you enjoy raw pasta.
  2. Dump the pasta, chicken, marinara, water, garlic powder, Italian seasoning, salt, and pepper into a 9×13-inch baking dish.

    Stir like you mean it.


  3. Cover with foil and bake for 30 minutes. Use this time to nap or question life choices.
  4. Uncover, stir, and sprinkle with mozzarella and Parmesan. This is where the magic happens.
  5. Mix breadcrumbs and olive oil, then sprinkle over the cheese.

    Because crunch is everything.


  6. Bake uncovered for 15 more minutes, or until the top is golden and the chicken is cooked (165°F, if you’re fancy with a thermometer).
  7. Let it sit for 5 minutes—unless you enjoy molten cheese burns. We don’t.

Storage: Because Leftovers Are Life

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave (for the lazy) or oven (for the crispy-obsessed).

Freezing? Cool completely, then freeze for up to 2 months. Thaw in the fridge overnight before reheating.

Why This Recipe Is a Game-Changer

It’s fast, foolproof, and family-friendly.

One dish means less cleanup, and the ingredients are pantry staples. Plus, it’s cheaper than takeout and tastes better. You get protein, carbs, and veggies (okay, tomato is a fruit, but let’s pretend) in one bite.

Meal prep? Double the recipe and thank yourself later.

Common Mistakes (Don’t Be That Person)

  • Using too much pasta: It expands. Stick to 2 cups unless you want a dry, sad casserole.
  • Forgetting the water: Pasta needs hydration, just like you after a workout.
  • Overbaking: Chicken turns to rubber.

    Set a timer.


  • Skipping the breadcrumbs: Texture matters. Don’t cheat yourself.

Alternatives for the Rebellious Cook

  • Vegetarian? Swap chicken for eggplant or mushrooms.
  • Gluten-free? Use GF pasta and breadcrumbs.
  • Spice it up: Add red pepper flakes or a splash of hot sauce.
  • Cheese overload: Throw in provolone or fontina for extra gooeyness.

FAQs (Because You Have Questions)

Can I use frozen chicken?

Technically yes, but thaw it first. Frozen chicken messes with cooking time and leaves you with unevenly cooked pasta.

No one wants that.

Can I make this ahead?

Absolutely. Assemble (without baking), cover, and refrigerate for up to 24 hours. Add 5-10 minutes to the bake time since it’s cold.

What if I don’t have breadcrumbs?

Crush crackers, chips, or even cereal (cornflakes work).

IMO, chips add a fun salty crunch.

Can I use jarred Alfredo instead of marinara?

Sure, but now it’s a different dish. Call it “Chicken Alfredo Bake” and pretend you meant to do that.

Final Thoughts

This casserole is the culinary equivalent of a mic drop. It’s easy, delicious, and solves the “what’s for dinner” crisis without drama.

Whether you’re a busy parent, a college student, or just someone who hates dishes, this recipe has your back. Now go forth and bake—your future self will high-five you.
