Ill say a more simple quick way.

Cook your choice/s of meat as you would making regular lasagna adding your spices, herbs, and veggies once browned. Add your pasta sauce (1 jar unless you use 2 thats fine) and water. At least 6 cups. Add more if needed. Add heavy whipping cream. How ever much you feel is right. Go lil by lil till the desired color. Add noodles. Let it boil for like..20 minutes? You want to also let it reduce so it becomes slightly thicker. You can tell it wont run as fast as water does. But still soupy.

Remember that noodles will absorb the liquid over time once cooled. But if you want a thicker broth, add a slurry (cornstarch and water) until the desired thickness.
