How to Make Mushroom Stroganoff Spaghetti Squash

1. Preheat the Oven: Start by preheating your oven to 400 °F. This ensures your spaghetti squash roasts evenly and becomes tender.

2. Prepare the Squash: Halve the spaghetti squash and scoop out its seeds. This step is crucial for creating the perfect base for your sauce!

3. Season and Roast: Brush the inside of the squash halves with olive oil, then season with salt and pepper. Place the halves cut-side down on a baking sheet and roast for about 40 minutes until tender and easily pierced with a fork.

4. Sauté Vegetables: In a large skillet, heat remaining olive oil and butter over medium heat. Add shallots and mushrooms, sautéing until golden brown and fragrant, which should take about 6-7 minutes.

5. Add Garlic and Thyme: Toss in the minced garlic and fresh thyme leaves. Cook for an additional minute, allowing the aromas to meld beautifully.

6. Deglaze with Wine: Pour in the dry white wine and let it reduce until mostly evaporated. This step adds depth to the sauce just what you want for a hearty dish!

7. Create the Sauce: In a bowl, whisk together vegetable broth, flour, Worcestershire sauce, and Dijon mustard. Then add this mixture to the skillet, simmering for about 5 minutes until thickened to your desired consistency.

8. Stir in Yogurt: Off the heat, stir in the Greek yogurt gently to maintain its creaminess without curdling. This will make your sauce wonderfully smooth.

9. Shred the Squash: Once your squash is roasted, use a fork to shred the spaghetti-like strands from each half. Top these strands generously with the mushroom stroganoff sauce, adding crispy garlic breadcrumbs if desired.

Optional: Garnish with extra thyme for a fresh touch.

Mushroom Stroganoff Spaghetti Squash Recipe FAQs

How do I choose a ripe spaghetti squash?
Absolutely! When selecting a spaghetti squash, look for a firm, tan shell free of dark spots or blemishes. The squash should feel heavy for its size, indicating ripeness. Avoid any squash that has soft spots or a shiny exterior, as these can indicate overripeness.

What s the best way to store leftover Mushroom Stroganoff Spaghetti Squash?
Store your leftovers in an airtight container in the refrigerator for up to 3 days. To keep it fresh and flavorful, ensure it s sealed tightly. Reheat gently either in the microwave or on the stove, stirring occasionally to maintain even warmth.

Can I freeze the Mushroom Stroganoff sauce?
Yes, you can freeze the mushroom stroganoff sauce, but it s best not to freeze the spaghetti squash itself. Cool the sauce completely, then transfer it to a freezer-safe container or resealable bag. It can be stored for up to 2 months. To reheat, thaw overnight in the fridge and then warm it gently on the stovetop, adding a splash of vegetable broth if it has thickened.

What if my sauce doesn t thicken?
Fear not! If your sauce doesn t thicken as expected, it might need more time on the stove. Continue simmering on low heat while stirring frequently for about 5 more minutes to allow the flour to activate. If it s still thin, whisk another teaspoon of flour with a little cold broth to create a slurry and then stir it into the sauce. That should do the trick!

Definitely! The Mushroom Stroganoff Spaghetti Squash is vegetarian and can easily be made vegan by substituting with vegan butter and yogurt. For gluten-free options, use gluten-free flour and ensure your Worcestershire sauce is gluten-free (or substitute soy sauce).

It s important to be cautious with some ingredients. While spaghetti squash itself is safe for dogs, be mindful of garlic, which can be toxic to pets in large amounts.
