Why This Mushroom Gravy Belongs on Your Thanksgiving Table

Quick and Easy to Make

This recipe is ready in under 30 minutes and made with everyday ingredients. No turkey drippings required, making it a great vegetarian-friendly option for your Thanksgiving spread.

Rich Flavor and Creamy Texture

The mushrooms add deep, earthy flavor, while the sour cream brings a gentle tang that balances beautifully with the savory onions and stock. The result is a smooth, creamy mushroom gravy that feels indulgent but isn’t heavy.

Great for Special Diets

You can easily adapt this recipe to be gluten-free or even vegan. It’s also a fantastic side dish for vegetarian guests at your Thanksgiving dinner.

Ingredients and Substitutions

Full Ingredient List

• 1 tablespoon olive oil
• 1 tablespoon butter
• 1 medium yellow onion, thinly sliced
• 1 garlic clove, minced
• 9 ounces brown mushrooms, sliced (cremini or baby bella)
• ¼ teaspoon ground black pepper
• 2 tablespoons all-purpose flour
• 1 ½ cups vegetable or chicken stock
• 2 teaspoons Dijon mustard
• ½ cup sour cream
• Salt and pepper to taste

Ingredient Tips

• Use fresh mushrooms for the best texture. Frozen mushrooms work in a pinch, but be sure to thaw and drain them thoroughly.
• Full-fat sour cream creates the creamiest texture, but light sour cream or crème fraîche also work.
• Chicken stock adds a bit more depth, but vegetable stock keeps this recipe vegetarian.
• Use sweet yellow onions for natural sweetness that balances the sour cream.

Easy Swaps

• Make it gluten-free by using cornstarch instead of flour (1 tablespoon cornstarch mixed with 2 tablespoons cold water).
• To make it vegan, use plant-based butter and dairy-free sour cream.
• You can use Greek yogurt if you're out of sour cream, but expect a slightly tangier flavor.

Step-by-Step Instructions

How to Make Mushroom Sour Cream Gravy

1. Heat the olive oil and butter in a large skillet over medium heat. Add the sliced onion and cook for 5 minutes, stirring occasionally, until soft and lightly caramelized.
2. Add the sliced mushrooms, garlic, and black pepper. Continue cooking for 5 to 6 minutes, until the mushrooms are golden brown and their moisture has evaporated.

3. Sprinkle the flour evenly over the mixture and stir to coat. Cook for 1 to 2 minutes to eliminate the raw flour taste.
4. Slowly pour in the stock, stirring or whisking constantly to prevent lumps. Bring to a simmer and let it cook for about 4 to 5 minutes until thickened.

5. Lower the heat and stir in the Dijon mustard and sour cream. Warm gently without letting it boil to keep the sauce smooth. Season with salt and pepper to taste.
6. Serve hot over your favorite Thanksgiving dishes.

Helpful Tips for Perfect Gravy

Best Cooking Practices

• Let the onions and mushrooms brown for full flavor. Don’t rush this step.
• Whisk the stock in slowly to prevent lumps and ensure a silky texture.
• Keep the heat low when adding sour cream to avoid curdling.

Avoid These Mistakes

• High heat after adding sour cream can cause it to split.
• Skipping the flour cook time may leave a raw taste.
• Overcrowding the pan will steam the mushrooms instead of browning them.

Time-Saving Shortcuts

• Use pre-sliced mushrooms and frozen onions for faster prep.
• Double the recipe and store extra gravy for leftovers or other meals.

Delicious Ways to Serve It

Perfect Thanksgiving Pairings

• Spoon over roast turkey or herb-buttered chicken.

Presentation Ideas

Drinks to Pair With

How to Store and Reheat Leftovers

Storing Tips

• Store in an airtight container in the refrigerator for up to 4 days.

Reheating Tips
