Step‑by‑Step Instructions for Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature ensures that your spaghetti squash will roast beautifully, developing a golden-brown color. While the oven warms up, gather your materials, including a large baking sheet and some parchment paper for easy cleanup when preparing the squash.
Step 2: Prepare the Spaghetti Squash
Carefully, halve the spaghetti squash lengthwise using a sharp knife, ensuring you maintain control. Scoop out the seeds with a spoon, then drizzle a little vegetable oil on the cut side. Season generously with salt and black pepper, then place the squash cut side down on the baking sheet. Roast for 30-40 minutes until tender, and the fork can easily pierce the flesh.
Step 3: Cook the Steak
While the spaghetti squash roasts, take your steak and season it with salt and pepper. Heat a skillet over medium heat and add a splash of vegetable oil. Once hot, add the steak, cooking it for about 3-5 minutes per side until it reaches your preferred doneness (medium-rare is ideal). Remove and let it rest for a few minutes before slicing it into thin strips.
Step 4: Make the Alfredo Sauce
In a medium saucepan over low heat, melt 4 tablespoons of unsalted butter. Once melted, pour in 1 cup of heavy cream, stirring to combine. Add in a pinch of ground nutmeg and 1 cup of freshly grated Parmesan cheese. Continuously stir until the cheese melts and the sauce is creamy. Season with salt and pepper to taste, then set aside while you finish preparing the dish.
Step 5: Combine Ingredients
Once the spaghetti squash is cool enough to handle, use a fork to fluff the insides, creating spaghetti-like strands. In a large mixing bowl, combine the fluffed squash with the sliced steak, 1.5 cups of frozen spinach (or fresh), sundried tomatoes, and half of the creamy Alfredo sauce. Mix thoroughly to ensure everything is well-coated and harmonious.
Step 6: Assemble and Bake Again
Spoon the delicious mixture back into the empty spaghetti squash halves. Top each half with shredded mozzarella cheese for that perfect melt. Place the stuffed halves onto the baking sheet and return them to the oven, baking for an additional 15 minutes. If you desire a golden top, switch to broil for the last 2-3 minutes, keeping a close eye to avoid burning.
Step 7: Serve with Extra Sauce
Remove the stuffed spaghetti squash from the oven and allow it to cool slightly. Drizzle the remaining Alfredo sauce over the tops just before serving for an extra creamy finish. Enjoy this Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash dish warm for a delightful culinary experience!
