Sauté aromatics: In a large pot, heat a drizzle of olive oil over medium heat. Add the chopped onion and minced garlic, stirring frequently until the onion is translucent, about 3–4 minutes.
Add chicken: Stir in the shredded chicken and cook for another 2–3 minutes until warmed through.
Create the soup base: Pour in the chicken broth and bring to a boil.
Incorporate noodles: Break the lasagna noodles into smaller pieces, then add them to the boiling broth. Cook for about 8-10 minutes, or until the noodles are just tender.
Add broccoli: Stir in the broccoli florets and cook for an additional 2–3 minutes, until they are tender and bright green.
Make it creamy: Reduce the heat to low, then stir in the milk and shredded cheddar cheese. Continue stirring until the cheese has melted and the soup is creamy.
Season and serve: Taste and adjust the seasoning with salt and pepper. Serve warm and enjoy!
Notes
Consider adding a dash of Italian seasoning or red pepper flakes for extra flavor.
