Tex-mex chicken white cheddar spaghetti is a creamy and cheesy pasta with a little Tex-mex kick.
Bring large pot of water to boil.
Melt butter and saute onions until softened, about 5 minutes. Stir in flour and cook 2 minutes.
Slowly whisk in chicken broth and milk to prevent lumps. Increase heat to thicken sauce.
Sprinkle in grated cheese and stir continuously to melt into sauce evenly. Stir in cumin, salt, pepper, jalapenos, jalapeno juice, chicken, cooked spaghetti and cilantro.
Toss to coat everything evenly in sauce. Taste and adjust seasonings. Serve warm with more cilantro.
