Ingredients

1 onion, chopped
2 tablespoons butter
16 ounces sliced mushrooms
8 ounces sour cream (about 1 cup)
1 teaspoon dried dill weed
½ teaspoon garlic powder
Salt and pepper, to taste
Optional: 1 tablespoon all-purpose flour (for thickening)

Sliced mushrooms and diced onions sautéing in butter in a cast iron skillet with a wooden spoon

Instructions

1. Sauté the Onion

In a cast-iron skillet (or heavy skillet) over medium heat, melt the butter. Add the chopped onion and sauté until soft and translucent, about 3–4 minutes.

2. Cook the Mushrooms

Add the sliced mushrooms to the skillet. Cook until they release their moisture and become soft and lightly golden, about 6–8 minutes.

3. Add the Creaminess

Reduce heat to low. Stir in the sour cream, dill weed, garlic powder, salt, and pepper.

If you prefer a thicker sauce, sprinkle in 1 tablespoon of flour and stir well to combine.

4. Simmer

Cover and cook over low heat for 3–5 minutes, just until heated through. Do not boil — keeping it at a gentle heat prevents the sour cream from separating.

5. Serve

Serve warm alongside grilled steak, roasted chicken, pork chops, or spooned over egg noodles or rice.

Makes 4 servings.

Tips for the Best Creamy Mushrooms

Use fresh mushrooms for the best flavor and texture.
Don’t overcrowd the pan — mushrooms brown better when they have space.
Fresh dill can be used instead of dried (about 1 tablespoon chopped).
For extra richness, add a splash of heavy cream.
