1 Can Equivalent

Ingredients

Scale
  • 2 tablespoons butter

  • ¼ cup finely diced onion

  • 1 clove garlic, minced

  • 1 cup finely chopped mushrooms
    (about 45 oz fresh mushrooms)

  • 2 tablespoons all-purpose flour

  • ½ cup chicken broth

  • ½ cup milk or half-and-half

  • ¼ teaspoon salt, or to taste

  • ¼ teaspoon black pepper

Instructions

  • Melt butter in a small saucepan over medium heat.

  • Add onion and cook until soft, about 3–4 minutes.

  • Add garlic and cook 30 seconds, until fragrant.

  • Add mushrooms and a pinch of the salt. Cook until mushrooms release their liquid and most of it evaporates.

  • Sprinkle flour evenly over the mixture. Stir well and cook for 1 minute.

  • Slowly whisk in chicken broth until smooth and thickened.

  • Stir in milk or half-and-half.

  • Simmer 3–5 minutes, stirring occasionally, until thick and condensed.

  • Season with remaining salt and pepper. Taste and adjust as needed.

  • Optional: Blend briefly for a smoother, more canned-style texture.

Notes

  • Soup should be thick, spoon-coating, and pourable but slow.

  • If too thick, add 1–2 tablespoons milk.

  • If too thin, simmer another minute.

  • Use anywhere a recipe calls for 1 can of condensed cream of mushroom soup.
