If anyone asks me what my biggest food weakness is, the answer is easy: pasta! But the truth is, my siblings love it even more than I do. Many evenings there is only one request at the dinner table: “Let’s have pasta tonight!” And the pasta they always mean is this one, my creamy chicken white sauce pasta, with juicy chicken, crunchy green capsicum and a sprinkle of red chilli flakes, exactly like the plate in the photo above.
It took me a few disasters to get here, though. So before the recipe, let me tell you what went wrong, because I think every home cook makes these same mistakes.
My White Sauce Disasters (and How I Fixed Them)
Lumps and a raw flour taste
The trouble started with the sauce. The moment I poured cold milk into the flour, it clumped into stubborn lumps, and I whisked until my arm ached. Worse, I was so scared of burning the butter that I didn’t cook the flour long enough. The sauce tasted like raw maida, not like the smooth, creamy sauce you get in a good restaurant.
The fix: cook the flour in the butter on low heat for a full 1 to 2 minutes, until it smells slightly nutty but is still pale. Then add warm milk slowly, whisking all the time. No more lumps, no more raw taste.
Mushy pasta and a sticky sauce
While I was fighting with the sauce, my pasta was overcooking. By the time I tossed it in, it was breaking apart, and the extra starch soaked up the sauce and turned it into a thick, sticky mass.
The fix: boil the pasta 1 to 2 minutes less than the packet says, because it keeps cooking in the sauce. And always save half a cup of the salty pasta water before draining. The night my sauce turned sticky, a splash of that water brought it back to life instantly, glossy and creamy again. It has been my secret ever since.
Ingredients You Will Need
The full list with exact quantities is in the recipe card below. A few notes from my kitchen:
- Pasta: I use penne because the tubes hold the sauce inside. Fusilli or macaroni also work.
- Chicken: boneless chicken cut into small cubes, quickly marinated with soy sauce, pepper and oregano for extra flavour.
- Capsicum: green capsicum adds colour and a fresh crunch. Mushrooms are a lovely optional addition.
- Cheese: cheddar gives a rich taste. You can mix in some mozzarella for extra stretch.
- Butter or margarine: both work. Butter gives a richer flavour.
My Tips for the Creamiest White Sauce Pasta
- Keep the heat low when making the sauce. High heat burns the butter and makes the milk catch at the bottom.
- Add cheese off the heat, then warm it gently. Cheese boiled hard turns grainy and oily.
- Don’t overcook the capsicum. Two minutes is enough to keep it bright green and crunchy.
- Serve immediately. White sauce pasta thickens as it sits. If it does, loosen it with pasta water or a splash of warm milk.
What to Serve with White Sauce Pasta
For a fun weekend spread at home, I serve this pasta with my chicken dynamite bites or a warm bowl of chicken corn soup. A simple green salad or garlic bread on the side is always welcome, and for the kids I sometimes add my creamy chicken tortilla triangles. If your family loves creamy, cheesy dishes, my smoky chicken lasagna is the next thing to try.
Storage and Reheating
Leftover white sauce pasta keeps in an airtight container in the fridge for up to 2 days. Reheat it in a pan on low heat with a splash of milk, stirring gently, until creamy again. I don’t recommend freezing it, because the sauce can split. For more on safe storage times, see my food storage guide.

Creamy Chicken White Sauce Pasta (No Lumps)
Ingredients
Equipment
Method
- Boil a large pot of water with 1 tbsp salt. Add the penne and cook 1 to 2 minutes less than the packet time, so it is just al dente. Before draining, save 1/2 cup of the pasta water.
- Toss the chicken with soy sauce, salt, black pepper and oregano. Heat 1 tbsp oil in a wok and cook the chicken on medium heat for 4 to 5 minutes until cooked through.
- Add the capsicum (and mushrooms, if using) and saute for 2 minutes, so the capsicum stays green and crunchy. Take everything out and keep aside.
- In the same wok, melt the butter with 1 tsp oil on low heat. Add the garlic and saute for 30 seconds until fragrant, without browning.
- Add the flour and stir continuously on low heat for 1 to 2 minutes, until it smells slightly nutty but is still pale. This cooks out the raw flour taste.
- Pour in the warm milk a little at a time, whisking continuously. Keep whisking until the sauce is smooth and thick enough to coat the back of a spoon, about 4 to 5 minutes.
- Turn the heat off. Stir in the cream, cheddar cheese, chilli flakes, oregano, black pepper and salt to taste. Turn the heat back to low and stir for 1 to 2 minutes until the cheese melts and the sauce is silky.
- Add the boiled pasta, chicken and capsicum. Toss well, adding a splash of the saved pasta water if the sauce feels thick.
- Sprinkle extra chilli flakes and fresh parsley on top and serve immediately.
Notes
- No lumps: use warm milk and add it slowly while whisking. If lumps still form, whisk hard off the heat or pass the sauce through a strainer.
- No raw flour taste: cook the flour in butter for a full 1 to 2 minutes on low heat before adding milk.
- Saucy, not sticky: pasta keeps absorbing sauce. Loosen it with the saved pasta water, and serve right away.
- Storage: keeps 2 days in the fridge. Reheat on low with a splash of milk.
Frequently Asked Questions
Why is my white sauce lumpy?
Usually the milk was too cold or added too quickly. Use warm milk and pour it in slowly while whisking. If lumps still form, take the pan off the heat and whisk hard, or strain the sauce.
How do I get rid of the raw flour taste?
Cook the flour in the butter for 1 to 2 minutes on low heat before adding the milk, and then let the sauce simmer gently for a few minutes until it thickens.
Can I make white sauce pasta without cheese?
Yes. It will still be creamy from the milk and cream. Add a little extra black pepper and garlic for flavour.
Can I make it without chicken?
Of course. Skip the chicken and add more vegetables, like corn, mushrooms and capsicum, for a vegetarian white sauce pasta.
