How to Make Creamy Spaghetti Squash
-
Preheat Oven: Begin by setting your oven to 400°F (200°C). This ensures a nice, even roast for the spaghetti squash, setting the stage for a delicious base.
-
Prepare Squash: Carefully slice the spaghetti squash in half and scoop out the seeds. Place the squash cut-side down on a baking sheet, then roast for about 35-40 minutes until it’s tender and easily pierced with a fork.
-
Cook Mushrooms: In a large skillet, heat a drizzle of olive oil over medium-high heat. Add the sliced cremini or baby bella mushrooms and sauté for 6-8 minutes until they’re beautifully browned and fragrant.
-
Add Garlic: Toss in the minced garlic and sauté for another minute until the aroma fills your kitchen. This step adds a delightful depth to your sauce!
-
Incorporate Spinach: Add the fresh spinach to the skillet, cooking until wilted, which should take around 2-3 minutes. The vibrant green color will brighten your dish!
-
Make Sauce: Lower the heat and pour in the heavy cream. Let it simmer gently for 3-5 minutes, which allows it to thicken to the perfect consistency. Stir in the Parmesan cheese and a dash of ground nutmeg, then season with salt and black pepper.
-
Scrape Squash: Once the squash is roasted, use a fork to scrape the inside, creating spaghetti-like strands that will serve as your delightful base.
-
Combine or Serve: You have the option to either plate the spaghetti squash separately and drizzle the cream sauce on top or mix everything right in the skillet. Serve warm and enjoy the comforting flavors!
Optional: Garnish with a sprinkle of crushed red pepper for an extra kick.

Storage Tips for Creamy Spaghetti Squash
Fridge: Store leftovers in an airtight container for up to 3 days. Gently reheat on the stove or microwave with a splash of cream to restore the creamy texture.
Freezer: Freezing is not recommended for this dish, as the spaghetti squash can become mushy once thawed, affecting the texture of your Creamy Spaghetti Squash with Mushroom and Spinach Cream Sauce.
Reheating: If you have leftover sauce, reheat it slowly on low heat, and add a bit of milk or cream if it thickens too much. Always taste and adjust seasoning before serving again.
Expert Tips for Creamy Spaghetti Squash
-
Avoid Overcooking Squash: Aim for fork-tender strands to maintain the perfect texture; overcooking can lead to mushy squash.
-
Sauté Mushrooms Well: Brown your mushrooms enough to release their umami flavor; this will elevate the overall taste of your Creamy Spaghetti Squash dish.
-
Fresh Spinach is Key: Using fresh spinach will give a vibrant color and taste; if using frozen, ensure it’s well-drained to avoid a watery sauce.
-
Let Sauce Thicken: Allow the heavy cream to simmer gently for the right creamy consistency; rushing this step can result in a thin sauce.
-
Season Thoughtfully: Don’t forget to taste as you go; adjust salt and pepper to your preference for a well-balanced flavor in your Creamy Spaghetti Squash.
-
Add Extra Flavors: For a zingy touch, consider adding lemon zest or crushed red pepper to brighten the dish; these small tweaks make a big difference!

-
Dairy-Free Delight: Substitute Parmesan cheese with nutritional yeast for a vegan version that still delivers a savory punch. This swap maintains the deliciously cheesy flavor while keeping it plant-based.

Coconut Cream: Use full-fat coconut milk in place of heavy cream to create an equally creamy and luscious sauce, perfect for those avoiding dairy. It provides a subtle sweetness that complements the savory elements beautifully.
-
Herbed Twist: Add fresh herbs like basil or thyme to elevate the flavor profile. Not only will it add freshness, but it also introduces a burst of color to your dish.
-
Heat it Up: For those who like a kick, sprinkle in crushed red pepper flakes or a dash of cayenne pepper. This added heat perfectly balances the creaminess and brings an exciting depth to each bite.

Creamy Spaghetti Squash with Mushroom and Spinach Recipe FAQs
How do I choose the right spaghetti squash?
Absolutely! When selecting a spaghetti squash, look for one that feels heavy for its size, with a firm texture and a hard, golden-yellow rind. Avoid squashes with dark spots or blemishes, as these may indicate spoilage. Aim for a squash that has a shiny surface, which typically ensures it’s fresh!
What’s the best way to store leftovers?
Very! Leftovers of your Creamy Spaghetti Squash with Mushroom and Spinach should be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it up on the stove or in the microwave with a splash of cream or milk to help restore its creamy texture.
Can I freeze the creamy sauce?
It’s recommended not to freeze the entire dish as the texture may change, but you can freeze the sauce separately. To do this, let it cool completely, then transfer it to a freezer-safe container. It can last for up to 3 months in the freezer. When you’re ready to use it, thaw it in the fridge overnight and gently reheat, adding fresh spinach and seasonings as needed.
What should I do if my sauce is too thin?
Not a problem! If your sauce seems too thin, here’s a quick fix: let it simmer on low heat for an additional 2-3 minutes to reduce and thicken. If you need to thicken it more, consider adding a bit of grated cheese or a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon water) and bring it back to a simmer, stirring continuously until it thickens to your desired consistency.
Is this recipe suitable for those with dairy allergies?
Yes indeed! You can easily adapt this recipe to be dairy-free by using full-fat coconut milk instead of heavy cream and substituting nutritional yeast for Parmesan cheese. This way, you can enjoy the same creamy goodness without any dairy! Just make sure to check any packaged ingredients for hidden dairy content, especially in the cheese substitutes.
Can I use frozen spinach instead?
Absolutely! If you’re out of fresh spinach, thawed and well-drained frozen spinach is an excellent substitute. Just make sure to squeeze out any excess water, as this will help maintain the creamy texture of your sauce. You’ll want to add it during the cooking process after the garlic to ensure it’s heated through and well incorporated.
