1 tablespoon butter
-
1 small onion, finely diced

2 cloves garlic, minced

3 cups chicken or vegetable broth

1 cup milk (or half-and-half for extra creaminess)

Sauté the aromatics: In a large pot over medium heat, melt the butter. Add diced onion and sauté until translucent, about 4–5 minutes. Add minced garlic and cook for another 30 seconds.

Add the mashed potatoes: Stir in the mashed potatoes, breaking up any clumps. Slowly whisk in the broth until the soup starts to smooth out.

Season and finish: Add salt, pepper, and cheese (if using). Stir until melted. Taste and adjust seasoning as needed.
