Ingredients You’ll Need

- 1 lb mushrooms (baby bella’s, cremini, or button mushrooms): These mushrooms offer a meaty, earthy base that soaks up the sauce beautifully.
- 1 medium or 2 small onions: When sautéed until golden, they add mild sweetness and depth to the dish.
- 3 Tbsp olive oil: This creates the perfect base for sautéing, enhancing flavor without overpowering.
- 3 Tbsp sour cream: Adds creaminess and a slight tang that transforms the mushrooms into a luscious sauce.
- Salt and pepper to taste: Essential seasonings to enhance and balance every flavor.
- Chopped green onion (optional for garnish): A fresh, vibrant touch that finishes the dish with a bit of crunch and color.
How to Make Mushrooms in a Sour Cream Sauce Recipe
Step 1: Prepare Your Ingredients
Start by finely chopping the onions and slicing the mushrooms into 1/4″ thick pieces. Preparing everything ahead ensures a smooth cooking process and helps the mushrooms cook evenly while the onions caramelize to perfection.
Step 2: Sauté the Onions
Heat 1 to 2 tablespoons of olive oil in a medium non-stick pan over medium heat. Add the chopped onions and sauté for several minutes until they become golden and fragrant. This step develops the natural sweetness of the onions, forming a rich base for the sauce.
Step 3: Cook the Mushrooms
In a separate large pan, warm the remaining 1 to 2 tablespoons of olive oil. Add the sliced mushrooms and sauté until they soften and start releasing their juicy goodness. If there’s excess liquid, drain it off but keep a little to maintain moisture and flavor when mixing later.
Step 4: Combine and Creamify
Now, bring the sautéed onions and mushrooms together in one pan. Stir in the 3 tablespoons of sour cream, and season generously with salt and pepper. The sour cream adds a dreamy creaminess that blends beautifully with the mushrooms’ earthiness and the sweet onions, creating the signature flavor of this Mushrooms in a Sour Cream Sauce Recipe.
