Easy Cheesy Chicken Pasta Bake Recipe

This easy cheesy chicken pasta bake is a comforting dinner made with cooked chicken, short pasta, peppers, tomatoes, mozzarella, and optional mature Cheddar.

Why You’ll Love This Recipe

This cheesy chicken pasta bake is the kind of dinner that earns a regular place in the weekly rotation. It uses familiar ingredients, requires simple preparation, and brings a generous casserole of saucy pasta to the table without complicated techniques.

The tomato sauce has a pleasant balance of sweetness from the onion and red pepper, gentle garlic flavor, and earthy oregano. Mozzarella melts into soft, creamy pockets, while mature Cheddar adds a sharper savory note if you choose to include it.

• Family-friendly flavor: The sauce is comforting without being spicy.
• Useful leftovers: Cooked chicken or rotisserie chicken fits perfectly here.

• Make-ahead potential: The assembled dish can be prepared ahead and baked when needed, provided it is cooled and stored safely.

Ingredients You’ll Need

The ingredient list is short, but each component has a clear job. Olive oil starts the sauce, onion and red pepper provide sweetness, and garlic and oregano give the tomatoes a savory Italian-inspired character.

• Olive oil: Use it to soften the vegetables and begin the sauce.
• Onion and red bell pepper: Finely chopping them helps them soften quickly and distribute throughout the bake.
• Garlic and oregano: These add aroma and depth without making the sauce heavy.
• Chopped tomatoes and tomato purée: The tomatoes create the sauce, while purée adds concentrated flavor and body.
• Short pasta: Use 300 g of penne or another short shape that can catch the sauce.
• Cooked chicken: You need 300 g of skinless cooked chicken breast, shredded or chopped into bite-size pieces.
• Cheese: Use 125 g mozzarella, plus 50–75 g grated mature Cheddar if you want a stronger, more browned topping.

Salt and freshly ground black pepper should be added to taste. Since canned tomatoes and cheeses vary in saltiness, season the sauce gradually and taste it before combining it with the pasta.

For a cozy starter before this casserole, serve a bowl of simple tortellini soup in a smaller portion, or keep the bake as the centerpiece of the meal.

How to Make It Step-by-Step

Step 1: Heat your oven to 200°C conventional, 180°C fan, or 400°F. Lightly grease a medium baking dish so the edges of the pasta do not cling while baking, then place the dish nearby for easy assembly.

Step 2: Bring a large pot of salted water to a boil and cook the pasta for about 2 minutes less than the package directions. This slight undercooking is important because the pasta continues cooking in the tomato sauce and oven; drain it well when finished.

Step 3: While the pasta cooks, heat 1 tablespoon of olive oil in a large frying pan. Add the finely chopped onion and red bell pepper, then cook for about 5 minutes, stirring occasionally, until the vegetables are softened but not deeply browned.

Step 4: Add the crushed or finely minced garlic and dried oregano to the pan. Cook for 30–60 seconds, stirring constantly, just until the garlic smells fragrant and the oregano has released its aroma.

Step 5: Pour in the 400 g can of chopped tomatoes and stir in 2 tablespoons of tomato purée. Season with salt and freshly ground black pepper, then simmer for approximately 8–10 minutes until the sauce thickens slightly and coats the back of a spoon.

Step 6: Add the 300 g of cooked shredded or chopped chicken to the sauce, followed by the drained pasta. Stir gently until the chicken is distributed throughout and every piece of pasta is coated without becoming mashed.

Step 7: Spoon the mixture into the greased baking dish and spread it into an even layer. Cover the surface with 125 g of sliced or torn mozzarella, then scatter over 50–75 g of grated mature Cheddar if using.

Step 8: Bake for 20–25 minutes, until the sauce is bubbling around the edges and the cheese is melted with golden patches. Let the casserole rest for 5 minutes before serving so it is easier to portion and the hot sauce does not run immediately across the plate.

Pro Tips for the Best Pasta Bake

The most important detail is to avoid fully cooking the pasta before it reaches the oven. Pasta that is cooked to its normal package time may absorb too much sauce during baking and become soft, while pasta cooked about 2 minutes less retains a better bite.

Drain the pasta thoroughly, but do not rinse it. The light starch on the surface helps the tomato sauce cling to the penne or other short pasta shape.

• Keep the chicken bite-size: Shredded or chopped pieces distribute more evenly than large chunks.
• Simmer the sauce: Eight to ten minutes gives the tomatoes time to thicken and the flavors time to combine.
• Use two cheeses: Mozzarella provides the classic melt, while mature Cheddar brings a bolder flavor and attractive browning.
• Watch the broiler: For a deeply golden top, broil or grill for only 1–2 minutes at the end and stay nearby because cheese can brown quickly.
• Rest before serving: Five minutes allows the pasta bake to settle while keeping it hot.

If you prefer chicken dinners with a sweet-and-savory finish, consider serving this casserole on another night alongside our honey-glazed chicken. It has a completely different flavor profile but works well for a varied dinner menu.

Serving Suggestions

This bake is filling enough to serve on its own, but a crisp side salad adds freshness and contrast to the rich cheese and tomato sauce. A simple green salad with a sharp vinaigrette is especially good because the acidity cuts through the creamy topping.

Steamed broccoli, green beans, or roasted zucchini also make easy vegetable sides. For a more relaxed family dinner, add warm garlic bread for mopping up the extra sauce.

Allow each serving to rest briefly on the plate before eating, as the center will be very hot. A small scattering of fresh herbs can add color, although the dish is flavorful and satisfying without additional garnish.

Storage, Reheating, and Make-Ahead Advice

Cool leftover pasta bake promptly, transfer it to a covered container, and refrigerate it. Enjoy refrigerated leftovers within a safe, practical timeframe and reheat until piping hot throughout.

For best results, reheat individual portions in the microwave or warm the casserole in a moderate oven with a little foil covering the top. The foil helps prevent the cheese from becoming too dark before the center is hot.

You can assemble the dish ahead of baking, but let hot ingredients cool appropriately before covering and refrigerating. If baking it straight from the refrigerator, allow extra time for the center to heat through and check that it is bubbling before serving.

Freeze portions only in suitable freezer-safe containers, and thaw them safely before reheating. The texture may be slightly softer after freezing, but the tomato sauce and cheese still make this a useful make-ahead dinner.

Method

 

Step-by-Step

1. Heat the oven to 200°C conventional, 180°C fan, or 400°F. Lightly grease a medium baking dish.
2. Cook the pasta in salted boiling water for about 2 minutes less than the package directions. Drain it well so the finished bake does not become watery or too soft.
3. Heat the olive oil in a large frying pan. Add the onion and red bell pepper, then cook for about 5 minutes until softened.
4. Add the garlic and dried oregano. Cook for 30–60 seconds, stirring often, until fragrant but not browned.
5. Stir in the chopped tomatoes and tomato purée. Season with salt and pepper, then simmer for approximately 8–10 minutes until the sauce is slightly thickened.
6. Stir the cooked chicken and drained pasta into the tomato sauce until everything is evenly coated.
7. Transfer the mixture to the prepared baking dish. Cover with the mozzarella and, if using, the grated mature Cheddar.
8. Bake for 20–25 minutes until bubbling and golden. Rest for 5 minutes before serving so the sauce settles slightly.

Notes

Use leftover or rotisserie chicken for convenience. Penne, fusilli, rigatoni, and other short pasta shapes work well. If starting with raw chicken, cook it separately until the thickest part reaches 74°C/165°F before adding it to the pasta. For extra browning, place the finished dish under the broiler or grill for 1–2 minutes, watching carefully.

Final Thoughts

When you need a dependable dinner that is warm, cheesy, and easy to prepare, this chicken pasta bake checks every box. The combination of tender chicken, short pasta, tomato sauce, mozzarella, and optional mature Cheddar creates a satisfying casserole with plenty of family-friendly appeal.

Remember to undercook the pasta slightly, simmer the sauce until it thickens, and give the finished bake 5 minutes to rest. With those simple details, you will have a bubbling 4-serving dinner ready in about 50–55 minutes.
