Heat a splash of oil in a large pot over medium heat. Add chopped onion, carrot, and minced garlic. Sauté for 5 minutes until softened and fragrant.
Add the sliced mushrooms and cook for another 3–4 minutes until they release their juices.
Stir in the diced potatoes and corn. Cook for an additional 2 minutes.
Pour in the vegetable broth and bring the mixture to a boil.
Reduce heat to low, cover, and let it simmer for 15 minutes or until the potatoes are tender.
Add the noodles and cook according to package instructions (about 7–10 minutes), until soft but not mushy.
Season with salt, black pepper, and basil to taste. Adjust seasoning as needed.
Serve hot and enjoy a nourishing bowl of rustic comfort.
