Mushroom Stroganoff Skillet

Ingredients

• 2 tablespoons Olive Oil: Used for sautéing the initial aromatics and mushrooms, providing a good base flavor. You can substitute with avocado oil or another neutral high-heat oil.
• 1 tablespoon Unsalted Butter: Adds richness and helps with browning the mushrooms beautifully. Using unsalted allows better control over the final seasoning.
• 1 large Yellow Onion (about 1.5 cups), finely chopped: Forms the aromatic foundation of the sauce, lending sweetness and depth when softened.
• 3-4 cloves Garlic, minced: Essential for its pungent aroma and flavor that complements the mushrooms and creamy sauce. Adjust amount based on personal preference.
• 1.5 pounds (about 24 oz) Cremini Mushrooms, cleaned and sliced: The star of the dish! Cremini (baby bella) mushrooms offer a deeper, earthier flavor than white button mushrooms. Slicing them about 1/4-inch thick ensures they cook evenly and retain some texture.
• 1 teaspoon Dried Thyme: Adds a classic herbaceous note that pairs perfectly with mushrooms and creamy sauces. You can use 1 tablespoon of fresh thyme leaves if preferred.
• 1 teaspoon Smoked Paprika: Lends a subtle smokiness and beautiful colour to the stroganoff, differentiating it from regular paprika (though sweet paprika can be substituted).
• 1/2 teaspoon Salt (or to taste): Essential for enhancing all the flavors. Start with this amount and adjust later.
• 1/4 teaspoon Black Pepper, freshly ground: Adds a touch of warmth and spice. Freshly ground offers superior flavor.
• 3 tablespoons All-Purpose Flour: Acts as a thickening agent for the sauce, creating a smooth, velvety consistency.
• 1/2 cup Dry White Wine (like Sauvignon Blanc or Pinot Grigio) OR Vegetable Broth: Used for deglazing the pan, lifting flavorful browned bits, and adding a layer of acidity (wine) or savory depth (broth).
• 3 cups Vegetable Broth, low sodium: The main liquid component of the sauce. Using low sodium allows for better salt control.
• 1 tablespoon Dijon Mustard: Adds a tangy complexity and helps to emulsify the sauce.
• 1 tablespoon Worcestershire Sauce (ensure vegetarian version if needed): Provides a significant umami boost and depth of flavor. Traditional Worcestershire contains anchovies, so check labels for a vegetarian/vegan alternative if required.
• 3/4 cup Sour Cream OR Plain Greek Yogurt (full fat recommended): The key ingredient for the signature creamy, tangy stroganoff finish. Full fat versions are less likely to curdle and provide richer results. Bring to room temperature before adding.
• Fresh Parsley or Chives, chopped: For garnish, adding a pop of fresh colour and flavour right before serving.
• Cooked Egg Noodles, Rice, Mashed Potatoes, or Polenta: For serving the stroganoff over.

Instructions

1. 1

2. 2

   Prepare the Base: Place a large, heavy-bottomed skillet (cast iron works wonderfully here) over medium heat. Add the olive oil and butter. Once the butter is melted and shimmering, add the finely chopped yellow onion. Sauté, stirring occasionally, until the onion softens and becomes translucent, about 5-7 minutes. Don’t rush this step; softened onions provide a crucial sweet base.

3. 3

   Cook the Aromatics: Add the minced garlic to the skillet and cook for about 1 minute more, stirring constantly until fragrant. Be careful not to burn the garlic, as it can become bitter.

4. 4

   Brown the Mushrooms: Increase the heat slightly to medium-high. Add the sliced cremini mushrooms to the skillet. It might seem like a lot, but they will cook down significantly. Spread them out as much as possible. Crucially, avoid stirring them too frequently for the first 5-7 minutes. Allow them to sit undisturbed so they can release their moisture and then begin to brown properly. Proper browning develops deep, savory umami flavor. Once they start browning, stir occasionally until they are nicely browned and tender, about 10-15 minutes total.

5. 5

   Season the Mushrooms: Once the mushrooms are well-browned, stir in the dried thyme, smoked paprika, salt, and freshly ground black pepper. Cook for another minute, stirring, until the spices are fragrant.

6. 6

   Create the Roux: Sprinkle the all-purpose flour evenly over the mushroom mixture. Stir continuously for about 1-2 minutes to cook out the raw flour taste. The mixture will look a bit pasty.

7. 7

   Deglaze the Pan: Pour in the dry white wine (or 1/2 cup of vegetable broth if not using wine). Scrape the bottom of the skillet with a wooden spoon or spatula to lift any browned bits (fond) stuck to the pan – this is packed with flavor! Let the liquid bubble and reduce slightly, about 1-2 minutes.

8. 8

   Build the Sauce: Gradually whisk in the 3 cups of vegetable broth, pouring slowly while whisking constantly to prevent lumps from forming. Stir in the Dijon mustard and vegetarian Worcestershire sauce.

9. 9

   Simmer and Thicken: Bring the mixture to a gentle simmer. Reduce the heat to low, cover the skillet loosely (leaving a small gap for steam to escape), and let it simmer for about 10-15 minutes, stirring occasionally. The sauce should thicken to a gravy-like consistency. If it seems too thick, you can add a splash more broth; if too thin, let it simmer uncovered for a few more minutes.

10. 10

    Temper the Cream: Turn off the heat completely. Let the skillet sit for a minute or two to cool slightly. This is important to prevent the sour cream (or Greek yogurt) from curdling. In a small bowl, whisk together the room-temperature sour cream (or Greek yogurt) with a ladleful (about 1/2 cup) of the hot mushroom sauce from the skillet. This process is called tempering and gently raises the temperature of the sour cream.

11. 11

    Finish the Stroganoff: Pour the tempered sour cream mixture back into the skillet. Stir gently until the sauce is smooth, creamy, and evenly combined. Do not return the skillet to direct heat or boil the sauce after adding the sour cream, as this can cause it to separate or curdle.

12. 12

    Taste and Adjust: Taste the stroganoff and adjust seasonings if necessary. You might need a pinch more salt, pepper, or even a tiny splash of lemon juice or vinegar if you want more tang.

13. 13

    Serve: Serve the Mushroom Stroganoff Skillet immediately over your choice of cooked wide egg noodles, fluffy rice, creamy mashed potatoes, or even polenta. Garnish generously with fresh chopped parsley or chives.
