What Ingredients are in Creamy Mushroom-Spinach Spaghetti Squash?
To make this cozy, comforting dish that perfectly balances decadence with nutrition, you’ll need just a handful of simple ingredients that transform into something truly special.
- 1 medium spaghetti squash
- 2 cups sliced mushrooms
- 2 cups fresh spinach
- 1 onion, diced
- 2 garlic cloves, minced
- 1/2 cup cream cheese
- 1/4 cup Parmesan cheese, plus extra for garnish
- Salt and pepper to taste
- Optional fresh herbs for garnish
The beauty of this recipe lies in its adaptability—you can use any variety of mushrooms you prefer (cremini, button, or even a mix with some shiitakes for extra flavor), and the cream cheese can be full-fat or reduced-fat depending on your preference.
How to Make this Creamy Mushroom-Spinach Spaghetti Squash
Step 1: Prepare and Bake the Spaghetti Squash
Cut 1 spaghetti squash in half lengthwise and scoop out the seeds with a spoon.
Place the halves cut-side down on a baking sheet and bake at 400°F for about 40 minutes, or until the flesh is tender enough that you can easily pierce it with a fork.
Step 2: Sauté the Aromatics
While the squash is baking, dice 1 onion and mince 2 garlic cloves.
Heat a tablespoon of olive oil in a large skillet over medium heat, then add the onion and garlic, cooking until they become translucent and fragrant—about 3-4 minutes.
Step 3: Brown the Mushrooms
Add 2 cups of sliced mushrooms to the skillet with the onions and garlic.
Cook them until they’ve released their moisture and started to brown nicely around the edges, which usually takes about 5-7 minutes.
This browning step is essential for developing that deep, savory flavor we’re after.
Step 4: Wilt the Spinach
Toss 2 cups of fresh spinach into the skillet with the mushroom mixture.
The pan might look overcrowded at first, but don’t worry—spinach wilts down dramatically.
Stir until the spinach has completely wilted, which happens surprisingly quickly.
Step 5: Create the Creamy Sauce
Reduce the heat to low and add 1/2 cup of cream cheese and 1/4 cup of Parmesan cheese to the skillet.
Stir until both cheeses have melted completely and formed a smooth, creamy sauce that coats all the vegetables.
Season with salt and pepper to taste.
Step 6: Prepare the Squash Strands
Once the squash is done baking, let it cool slightly until you can handle it comfortably.
Use a fork to scrape the insides of the squash, which will separate into spaghetti-like strands—hence the name!
The strands should come away easily from the skin.
Step 7: Combine and Stuff
Mix about half of the squash strands directly into your creamy mushroom-spinach mixture, stirring to combine.
Then spoon this mixture back into the empty squash shells, creating beautiful, edible vessels for your creamy creation.
For perfect, professional-looking results, consider using tools from a premium baking set that will elevate your culinary presentation.
Step 8: Final Baking
Return the stuffed squash halves to the oven and bake for an additional 10 minutes at 400°F.
This final bake helps the flavors meld together and gives the top a slight golden finish.
Before serving, sprinkle with additional Parmesan cheese and fresh herbs if desired.
What to Serve with Creamy Mushroom-Spinach Spaghetti Squash
This veggie-packed dinner is pretty satisfying on its own, but a few simple sides can turn it into a complete meal.
A crisp green salad with a lemony vinaigrette cuts through the richness beautifully, while garlic bread makes the perfect vehicle for scooping up any escaped filling.
For protein lovers, a simple grilled chicken breast or roasted chickpeas work wonderfully alongside.
Wine-wise, a glass of chilled Pinot Grigio or unoaked Chardonnay complements those creamy, earthy flavors.
And if you’re serving this for a weekend lunch, consider adding a small bowl of fresh fruit for a sweet contrast to all that savory goodness.
The best part? Most of these sides take just minutes to prepare while your squash is in the oven.
Creamy Mushroom-Spinach Spaghetti Squash Substitutions and Variations
- Flavor Enhancers: A splash of white wine when sautéing mushrooms or red pepper flakes for heat takes this up a notch.
- Fresh Herbs: Thyme and rosemary complement mushrooms beautifully, while basil or parsley brighten the finished dish.
- Fall Twist: Add roasted butternut squash cubes and sage for an autumn version.
- Topping Ideas: Toasted pine nuts, breadcrumbs, or everything bagel seasoning add delightful crunch.
Leftovers and Storage for this Creamy Mushroom-Spinach Spaghetti Squash
This stuffed spaghetti squash keeps beautifully in the refrigerator for up to 3-4 days when stored in an airtight container.
The flavors actually meld and deepen overnight, making day-two servings sometimes even more delicious than the first round!
To reheat, microwave individual portions for 2-3 minutes or warm in a 350°F oven for about 15 minutes until heated through.
A little trick to prevent dryness? Sprinkle a tiny bit of water over the squash before reheating.
For freezing (yes, you can!), store cooled portions in freezer-safe containers for up to 1 month.
Thaw overnight in the refrigerator before reheating. The texture might change slightly, but a fresh sprinkle of Parmesan and herbs will revive it nicely.
