Can I use rotisserie chicken?
Absolutely. Skip the chicken cooking step and stir in 3 to 4 cups shredded rotisserie chicken (about 1 pound) when the noodles are almost tender, just long enough to warm through.
How do I keep the sauce from getting too thick?
Two things help: stir the flour into the melted butter and onions until it turns smooth and a little golden, then add liquid gradually while whisking. If it thickens too much while simmering, loosen it with warm broth or milk a few tablespoons at a time.
Can I use different noodles?
Egg noodles are ideal because they cook quickly and stay tender. If you use rotini or penne, you will likely need more broth and a longer simmer. Add liquid as needed and cook until the pasta is truly tender.
Is this basically chicken pot pie filling?
Pretty much, but in noodle form. If you want pot pie vibes, add a pinch of thyme and serve with buttery biscuits.
What veggies work best?
Peas, carrots, corn, chopped spinach, or green beans all work. Frozen mixed vegetables are totally welcome here.
Can I swap the milk?
Yes. Whole milk gives the silkiest result, but 2 percent works too. For extra richness, use half-and-half. If you only have 1 percent or skim, it will still work, just keep the simmer gentle and expect a slightly thinner, less plush sauce.
