FOR THE BROTH
Place the chicken in a large stockpot and fill with enough cold water to cover the chicken.
Add vegetables, garlic, bay leaves, and salt and pepper.
Bring to boil, and then reduce to simmer until chicken is cooked through and vegetables are soft.
Remove chicken and set aside.
Drain broth and discard vegetables. Cool both chicken and broth.
When chicken has cooled, remove from bones and cut into nice big chunks.
NOTE: It’s perfectly fine to use canned chicken broth. Just skip this step and proceed to the next section.
FOR THE SOUPIn a large stockpot, sauté onion until softened and starting to caramelize
Add chicken broth and bring to a low boil.
Add carrots, celery, peppers, salt, pepper, and bay leaves. Reduce to simmer and cook until tender.
Remove bay leaves or keep in for awhile but always remove before serving since they are very dangerous to eat whole.
Stir in cooked chicken. (If using raw chicken pieces, add them now and cook until just cooked through)
Stir in cooked and reserved lasagna noodles.
If you prefer a more brothy soup, stop here. Check for seasoning and you are done.
If you prefer a thicker soup with a heartier consistency, it’s time to add the Cornstarch Slurry. Add 4 Tablespoons Cornstarch to a small bowl. Slowly add and whisk in 1/4-cup cold water or broth. Stir until mixture is completely smooth.
Gradually stir this slurry into the hot soup mixture (just start with half of it to make sure the soup doesn’t get too thick). Bring to boil and boil for one minute, then reduce to simmer. If soup is thick enough, you are done. If not, add the remaining slurry and repeat the steps above. NOTE: if you boil a cornstarch thickened soup for too long, the thickening will break down so keep to a simmer if you can.
