This is a baked penne dish with ground chicken, a quick homemade tomato sauce, baby spinach, and a cheddar crust. It comes together in under an hour using one skillet and one baking dish, which makes it a realistic option on a busy weeknight. The ground chicken keeps it lighter than a beef bake without sacrificing the meaty texture you want in a pasta casserole.
The technique that matters
The two things that actually affect the final dish are cooking the pasta short of done and layering the cheese in the middle as well as on top. Pull the penne out while it still has a firm bite — it will absorb liquid and finish cooking in the oven, so pasta that goes in fully cooked comes out soft and heavy. The mid-layer cheese matters because it melts into the sauce rather than just sitting on the surface, which means you get cheese in every forkful rather than just the top. Make sure ground chicken reaches an internal temperature of 165°F (74°C) before it goes into the baking dish — it should be fully cooked in the skillet, not pink anywhere, since the oven time is only long enough to melt cheese, not to finish raw meat.
Common problems and fixes
- Dry bake after it comes out of the oven: The pasta absorbed too much sauce before baking. Add a splash of water or unsalted chicken stock to the skillet mixture just before transferring to the baking dish — two or three tablespoons is enough to keep it saucy.
- Watery bake with liquid pooling at the bottom: The spinach released too much moisture. Let it wilt fully in the skillet and stir it for an extra minute so excess water cooks off before you add the pasta.
- Cheese topping that browns too fast before the center is hot: Cover the dish loosely with foil for the first ten minutes, then uncover for the last five to get the crust without burning.
- Bland ground chicken: Season the chicken directly in the skillet with salt and pepper before adding the tomatoes — relying only on the sauce to carry the seasoning leaves the meat flat.
- Sauce that tastes sharp or thin: The brown sugar in the recipe is doing real work here. If you skip it, the canned tomatoes can taste acidic and one-dimensional. Keep it in.
Shopping notes
- Whole peeled tomatoes vs. diced: Whole peeled tomatoes break down into a thicker, less watery sauce. Diced canned tomatoes work but tend to stay chunky and release more liquid — crush them with a spoon before adding if that’s what you have.
- Ketchup note for Australian and UK readers: The recipe lists ketchup as the US term and notes that tomato sauce in Australia and the UK is the equivalent. This refers to the homemade tomato sauce built in the recipe, not bottled ketchup — do not substitute bottled ketchup, which is much sweeter and will throw off the balance.
- Cheddar swap: Medium or sharp cheddar both work. Skip the garnish of fresh herbs on top — not worth the extra dish. If you want more depth, mix in a handful of low-moisture mozzarella with the cheddar for better melt.
- Whole-grain penne: The recipe specifies whole-grain, which holds its shape better during baking than regular penne. Regular penne is a fine substitute but watch the al dente timing carefully since it softens faster.
Leftovers and meal prep
Leftovers keep well in an airtight container in the fridge for up to four days. Reheat individual portions in the microwave with a tablespoon of water added to prevent drying out, or cover the whole dish with foil and warm it in a 350°F oven for about 15 minutes. This bake also freezes cleanly — portion it into freezer-safe containers before freezing and use within two months for best texture. For meal prep, you can assemble the entire unbaked dish up to 24 hours ahead, cover it tightly with foil, and refrigerate it; add five minutes to the bake time if it goes into the oven cold from the fridge.

Cheesy Ground Chicken Pasta Bake
Ingredients
Homemade Tomato Sauce Ingredients
1 tablespoon olive oil
½ medium white onion - finely diced
3 cloves garlic - minced
14 ounces tomatoes - whole and peeled
1 tablespoon tomato paste
1 ½ teaspoon dried basil
1 tablespoon brown sugar
¼ teaspoon salt
¼ teaspoon ground black pepper
Pasta Bake Ingredients
- 12 ounces penne - whole-grain
2 cups ketchup (tomato sauce Australia and UK) - homemade
3 cups baby spinach
1 ½ cups cheddar cheese - shredded
Instructions
- Preheat oven to 375 degrees Fahrenheit. Prepare your mis-en-place: dice onion, mince garlic, slice sausage, and open tomatoes and paste cans.
- Boil a large pot of water on your stove and cook pasta al dente. The pasta will finish cooking in the oven. Drain pasta and set aside.
- Add 1 tablespoon of olive oil and diced onion to a large skillet on medium heat. Sauté onion for 2 to 3 minutes until soft. Add minced garlic and cook until fragrant. Add tomatoes, tomato paste, brown sugar, basil, salt and a few twists of pepper. Simmer for about 2 to 3 minutes, then add the chicken. Simmer for another 5 minutes, then add spinach and give it a few stirs to allow spinach to wilt.
- Add pasta to the sauce, stir to coat, and add half the mixture to a baking dish. Sprinkle with ¾ cup of grated cheese of choice. Pour the remaining mixture into the dish and cover with the remaining cheese.
- Bake for 15 to 20 minutes, or until cheese has melted and the top is slightly brown and crusty.

Your questions, answered
Can I use ground turkey instead of ground chicken?
Yes, ground turkey is a direct swap and behaves almost identically in this recipe. Like ground chicken, it must reach 165°F (74°C) internally before the dish goes into the oven — check it in the skillet before transferring.
Do I have to make the tomato sauce from scratch, or can I use jarred?
You can use a plain jarred marinara in a pinch — use about two cups. The homemade version takes only about ten minutes and gives you control over sweetness and salt, but a good-quality jarred sauce is a reasonable shortcut on a rushed night.
Can I assemble this ahead and bake it later?
Yes, you can assemble it up to 24 hours in advance and refrigerate it covered. Add roughly five extra minutes to the bake time to account for it starting cold.
My family doesn’t eat spinach. Can I leave it out or swap it?
You can leave it out entirely without changing anything else in the recipe. If you want a vegetable in there, finely diced zucchini or mushrooms sautéed in the skillet before the tomatoes are added both work well.
How do I know the ground chicken is fully cooked in the skillet?
It should be completely opaque with no pink remaining, and an instant-read thermometer inserted into the thickest part of the meat in the pan should read 165°F (74°C). Do not rely on color alone — use a thermometer if you have one.
Can I use a different pasta shape?
Short, sturdy shapes work best — rigatoni, ziti, or rotini all hold up to baking without going mushy. Avoid thin pasta like spaghetti or linguine, which clump together and don’t distribute the sauce evenly through the bake.
