Onion Mushroom Stroganoff Ingredients
For the Sauce
- Unsalted Butter – Adds richness and flavor; substitute with vegan butter for a dairy-free option.

- Soy Sauce – Provides umami richness; replace with tamari for a gluten-free version.
- Dijon Mustard – Adds a subtle tang; it can be omitted or replaced with yellow mustard when needed.
- Sour Cream – Brings creaminess and tang; plant-based sour cream is a great vegan alternative.

How to Make Onion Mushroom Stroganoff
-
Prepare Pasta: Boil a large pot of salted water, then add wide egg noodles. Cook according to package instructions until tender, about 7-9 minutes. Drain and set aside.
-
Sauté Onions: In a skillet, heat unsalted butter and olive oil over medium heat. Add finely sliced yellow onions and lightly sauté for 5-6 minutes, until they are soft and lightly golden.
-
Cook Mushrooms: Incorporate smooth, sliced cremini or button mushrooms into the skillet. Stir occasionally and cook until browned and their liquid evaporates, about 7-8 minutes.
-
Build Flavor Base: Add minced garlic to the skillet, cooking for 1 minute until fragrant. Sprinkle in all-purpose flour and sweet paprika, cooking briefly to remove any raw flour taste.
-
Deglaze: Pour in the dry white wine or vegetable broth while scraping any brown bits from the skillet. Let it simmer until reduced by half, around 2-3 minutes.
-
Create Sauce: Mix in vegetable broth, soy sauce, and Dijon mustard. Bring to a gentle simmer for 4-5 minutes until the sauce slightly thickens.
-
Finish with Sour Cream: Lower the heat and carefully stir in the sour cream until everything is well combined and warmed through. Be sure not to boil to maintain a smooth texture.
-
Serve: Spoon the creamy onion mushroom stroganoff over the prepared noodles and garnish generously with fresh parsley for that pop of color and flavor!
Optional: A sprinkle of smoked paprika on top adds an extra flavor dimension.

How to Store and Freeze Onion Mushroom Stroganoff
- Fridge: Store leftovers in an airtight container for up to 3 days. Make sure to cool the stroganoff completely before sealing to prevent condensation.
- Freezer: For longer storage, freeze in a sealed container or freezer bag for up to 2 months. To reheat, thaw overnight in the fridge before gently warming on the stovetop with a splash of broth.
- Reheating: Reheat leftovers on low heat, stirring frequently. Add a little vegetable broth if the sauce is too thick to ensure a creamy texture.
- Avoid Freezing Noodles: It’s best to freeze the sauce separately from the noodles, as cooked pasta can become mushy after freezing.
Make Ahead Options
These Onion Mushroom Stroganoff are perfect for busy home cooks looking to save time during the week! You can prepare the sauce and sauté the vegetables up to 3 days in advance. Simply complete steps 2 through 7, allowing the mixture to cool before storing it in an airtight container in the refrigerator. This not only helps with meal prep but also enhances the flavors as they meld together overnight. When you’re ready to serve, just reheat the sauce in a skillet over low heat, adding a splash of vegetable broth to loosen it if necessary. Cook the noodles fresh to ensure they remain tender and take just minutes, giving you a delicious, homemade meal with minimal effort!

Expert Tips for Onion Mushroom Stroganoff

- Herb Variations: Experiment with fresh herbs like thyme or dill for a unique twist that brightens up your onion mushroom stroganoff.
- Pasta Alternatives: If you prefer a lighter option, try serving the stroganoff over zucchini noodles or cauliflower rice for a delightful twist.
