Step‑by‑Step Instructions for Steak Gorgonzola Alfredo Spaghetti Squash
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is ideal for roasting your spaghetti squash until it becomes tender and easily shredded. Meanwhile, gather a baking sheet where you’ll place the squash, making sure it’s ready to accommodate the halves cut lengthwise.
Step 2: Prepare the Spaghetti Squash
Carefully slice the spaghetti squash in half lengthwise, using a sharp knife. Remove the seeds and stringy insides with a spoon. Drizzle the cut sides with vegetable oil, sprinkling salt and pepper generously for flavor. Place the squash cut-side down on the baking sheet and roast it in the oven for 30-40 minutes, until the flesh is fork-tender.
Step 3: Cook the Steak
While the squash is roasting, season your choice of steak (about 3/4 pound) with salt and black pepper. Heat a skillet over medium-high heat and add a touch of oil. Cook the steak for about 3-5 minutes on each side, or until it reaches just below your preferred doneness. Remove it from the skillet and let it rest before slicing it thinly.
Step 4: Make the Alfredo Sauce
In a medium saucepan, melt 8 tablespoons of unsalted butter over medium heat. Add 2 cups of heavy cream, stirring continuously until combined and warmed through. Incorporate 1.5 cups of freshly grated Parmesan cheese slowly, allowing it to melt into a creamy sauce. Add 1/4 teaspoon of ground nutmeg, and season with salt and pepper to taste to enhance the rich flavor of your Steak Gorgonzola Alfredo.
Step 5: Shred the Spaghetti Squash
Once the spaghetti squash is cooked and slightly cooled, use a fork to carefully shred the flesh into noodle-like strands. This step is crucial, as it transforms the squash into your low-carb pasta substitute. Set aside these delicious “noodles” as you prepare to combine them with the other hearty ingredients.
Step 6: Combine Ingredients
In a large mixing bowl, combine the shredded spaghetti squash, sliced steak, 3/4 cup of thawed and drained spinach, 1/4 cup of sundried tomatoes, and 4 ounces of gorgonzola cheese crumbles. Pour in a portion of your creamy Alfredo sauce and toss everything together gently to ensure even coating, creating the flavorful mixture for your Steak Gorgonzola Alfredo Spaghetti Squash.
Step 7: Bake the Filled Squash
Spoon the savory mixture back into the empty squash halves, filling them generously. Top each filled squash half with 1 cup of grated mozzarella cheese, ensuring a delightful cheesy finish. Place the baking sheet in the oven, baking for an additional 15 minutes until the mozzarella is melted and bubbly. For an extra touch, broil briefly to achieve a golden brown top if desired.
Step 8: Serve and Enjoy
Remove the stuffed spaghetti squash from the oven and allow it to cool for a moment. Serve hot, drizzled with any remaining Alfredo sauce for that creamy touch. The Steak Gorgonzola Alfredo Spaghetti Squash is now ready to be enjoyed, offering a comforting and satisfying dish with every flavorful bite!

Steak Gorgonzola Alfredo Spaghetti Squash Recipe FAQs
What is the best way to select a spaghetti squash?
Absolutely! When selecting a spaghetti squash, look for one that feels heavy for its size and has a firm outer skin without any dark spots or soft areas. A squash weighing between 2-3 pounds will provide a nice serving. Avoid ones with blemishes as they might not be fresh.
How long can I store leftover Steak Gorgonzola Alfredo Spaghetti Squash?
The filled spaghetti squash can be refrigerated in an airtight container for up to 3 days. Reheat in the oven to maintain its creamy texture, as microwave heating can cause the squash to become watery.
