Simple Chicken Pasta Bake Recipe With Jar Sauce: 30-Minute Cheesy Comfort

This pasta bake delivers comfort food without the fuss, using a smart shortcut that doesn’t sacrifice flavor.

I developed this method after too many weeknights spent juggling multiple pots and pans. The jar sauce saves time while still creating a rich, satisfying base.

You’ll get tender chicken, al dente pasta, and a bubbling cheesy topping—all in 30 minutes. It’s the kind of meal that feels like a hug on a busy evening.

Perfect for feeding a family or meal prepping for the week. Here’s how to make it.

Ingredients for Simple Chicken Pasta Bake Recipe with Jar Sauce

Pantry staples meet jarred shortcuts for this cozy, cheesy weeknight dinner.

The jar sauce is the hero shortcut here. Rao’s or Victoria are my go-tos for rich flavor without added sugar. Chicken breast stays juicier than thighs in this bake—just cube them evenly so everything cooks at the same rate. Grab the cheese from the deli counter (they’ll shred it fresh) or use pre-shredded in a pinch (the good stuff, not the pre-shredded kind with anti-caking agents).

No penne? Rotini or fusilli work great—any short pasta grabs the sauce. Swap mozzarella for Monterey Jack if that’s what you’ve got. Want more veg? Toss in frozen spinach (thawed and drained) between the pasta and cheese layers. The Italian seasoning can be a pinch of dried oregano and basil if that’s all you’ve got in the spice cabinet.

Bake and freeze leftovers in portions for up to 3 months. Reheats beautifully—just cover with foil and warm at 350°F until bubbly. Fresh is best within 4 days in the fridge.

Step-by-Step Instructions for Chicken Pasta Bake

Easier than takeout, and you probably have everything already.

Step 1: Sauté Chicken and Aromatics

Heat the 2 tbsp Olive Oil in a large skillet over medium-high heat. Add the 1.5 lb Chicken Breast pieces and cook for 5-6 minutes until lightly browned and cooked through. I like to leave them undisturbed for the first 2-3 minutes to get a nice sear.

Add the finely diced 1 whole Onion and minced 3 cloves Garlic Cloves to the skillet. Cook for another 2-3 minutes until the onion softens and becomes translucent. This builds the flavor base for your bake.

Stir in the 1 tsp Dried Italian Seasoning, 1 tsp Salt, 0.5 tsp Black Pepper, and 0.25 tsp Red Pepper Flakes. Cook for 30 seconds until fragrant, then remove from heat.

Step 2: Cook Pasta and Combine

While the chicken cooks, bring a large pot of salted water to a boil. Add the 12 oz Penne Pasta and cook for 2 minutes less than package directions—it’ll finish in the oven. You want it al dente with a slight bite.

Drain the pasta and return it to the pot. Add the cooked chicken mixture and the 24 oz Jarred Marinara Sauce. Stir to combine evenly, making sure the pasta is well coated. The sauce should cling to the pasta without pooling at the bottom.

Step 3: Layer Cheeses and Bake

Transfer half of the pasta mixture to a greased 9×13-inch baking dish. Sprinkle 1 cup Shredded Mozzarella Cheese and the 1 cup Shredded Cheddar Cheese evenly over the top. This first cheese layer ensures gooey goodness in every bite.

Add the remaining pasta mixture, spreading it evenly. Top with the remaining 1 cup Shredded Mozzarella Cheese and the 0.5 cup Grated Parmesan Cheese. The Parmesan will add a sharp, nutty depth to the dish.

Bake at 375°F for 15-20 minutes until the cheese is melted and bubbly with golden brown spots. For extra browning, broil for 1-2 minutes at the end—watch it closely to avoid burning.

Step 4: Rest and Serve

Let the dish rest for 5 minutes after removing it from the oven. This allows the cheese to set slightly, making it easier to serve. The edges should be crispy, and the center should be hot and bubbling.

Use a spatula to cut into portions. Each serving should have a mix of pasta, chicken, and that irresistible cheesy topping. Garnish with extra Parmesan or fresh herbs if you’d like, though it’s delicious as is.

Creative Variations of These Flavors

Creamy Alfredo Twist

Swap the marinara for a 15 oz jar Alfredo sauce—I love Bertolli for its rich, velvety texture. Add ½ cup heavy cream to the pasta mixture before baking for extra decadence. The result is a luxurious, cheesy bake that kids absolutely adore. 💛

Spicy Arrabbiata Kick

Use a 24 oz jar arrabbiata sauce instead of marinara. I recommend Newman’s Own for its bold tomato and chili flavor. Add ½ tsp crushed red pepper to the chicken while cooking to amplify the heat. Top with pepper jack cheese for a spicy finish.

Veggie-Packed Version

Stir in 2 cups chopped spinach or diced bell peppers after combining pasta with the sauce. I often grab frozen spinach from my local market—just thaw and drain it well. This adds color and nutrition without changing the cooking time. 🥗

Taco-Inspired Flare

Replace marinara with 1 cup salsa and 1 cup sour cream. Use 1 tbsp taco seasoning with the chicken. Top with 1 cup shredded Monterey Jack and crushed tortilla chips after baking. It’s a fun fusion that my family requests often.

Mediterranean Style

Add ½ cup crumbled feta and ¼ cup chopped kalamata olives between the pasta layers. Use 1 tsp dried oregano instead of Italian seasoning. The briny olives and tangy feta give this dish a bright, fresh twist.

Breakfast-for-Dinner

Use 8 oz cooked breakfast sausage instead of chicken. Add ½ cup shredded hash browns to the pasta mixture. Top with 1 cup shredded cheddar and bake as usual. It’s a hearty way to start—or end—your day. 💪
