Finely chop the onion and mince the garlic cloves.
Drain the canned corn well.
Heat the vegetable oil in a pot over medium heat. Add the chopped onion and garlic and sauté until fragrant and translucent, about 3-5 minutes.
Add the drained corn and stir everything well. Let it sauté for another 2 minutes.
Stir the vegetable broth powder into the water until it has completely dissolved.
Pour the prepared vegetable broth into the pot with the corn and onions. Bring the soup to a boil.
Reduce the heat and let the soup simmer gently for about 5-7 minutes to allow the flavors to combine.
Remove the pot from the heat and blend the soup with an immersion blender until creamy. If you want a particularly fine soup, you can pass it through a sieve.
Season the soup with salt, pepper, and paprika powder.
Serve the hot corn soup immediately, optionally garnished with fresh herbs, e.g., parsley.
