Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash Ingredients
For the Squash
• Spaghetti Squash – Choose a squash weighing between 2-3 pounds for the best texture in this low-carb dish.
For the Steak
• Steak – Any cut works here, and leftover cooked steak is a great substitution for a quicker prep.
For the Sauce
• Unsalted Butter – 8 tablespoons create a rich base for the Alfredo sauce; salted butter can be used with adjusted salt.
• Heavy Cream – 2 cups add the luxurious creaminess to this dish; feel free to use lighter cream alternatives if desired.
• Ground Nutmeg – 1/4 teaspoon enhances the flavor profile of the sauce; it’s optional but highly recommended.
• Freshly Grated Parmesan Cheese – 1.5 cups adds depth to the Alfredo sauce; while pre-grated can be used, fresh is best for a creamy melt.
For the Veggies
• Frozen Spinach (3/4 cup; thawed, drained) or Fresh Spinach (1.5 cups) – Fresh spinach brings better flavor, while frozen is a convenient option.
• Sundried Tomatoes (1/4 cup) – They add a sweet and tangy note; fresh tomatoes work if you’re in a pinch.
For the Toppings
• Gorgonzola Crumbles (4 ounces or about 3/4 cup) – This cheese brings a unique sharpness; you can substitute with blue cheese if you prefer.
• Mozzarella Cheese (1 cup, grated) – For a delightful melty topping; other melting cheeses can be used if you want a variation.
For Seasoning
• Salt & Black Pepper – Essential for enhancing flavor; be sure to adjust to taste as the cheese can add saltiness.

Step‑by‑Step Instructions for Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash
Step 1: Preheat and Prepare the Squash
Begin by preheating your oven to 400°F (204°C). Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds using a spoon. Drizzle vegetable oil over the cut sides, then season with salt and pepper to enhance the flavor. Place the squash cut-side down on a baking sheet lined with parchment paper, allowing it to roast evenly.
Step 2: Roast the Squash
Roast the spaghetti squash in the preheated oven for 30–40 minutes, or until the flesh is tender and easily pierced with a fork. You’ll know it’s done when the edges start to caramelize slightly. Once cooked, remove it from the oven and let it cool before handling, allowing it to reach a manageable temperature for shredding.
Step 3: Cook the Steak
While the squash is roasting, heat a skillet over medium heat and add a drizzle of vegetable oil. Season the steak with salt and pepper, then sear it in the hot skillet until it’s nearly cooked to your liking—about 4–5 minutes per side for medium-rare, depending on thickness. Once cooked, remove the steak from the skillet and let it rest for a few minutes before slicing thinly.
Step 4: Make the Alfredo Sauce
In a saucepan over medium-low heat, melt the 8 tablespoons of unsalted butter. Add the 2 cups of heavy cream and 1/4 teaspoon of ground nutmeg, stirring gently until combined and warmed through. Gradually whisk in 1.5 cups of freshly grated Parmesan cheese until melted and smooth. Adjust the seasoning with salt and pepper as needed for a flavorful sauce.
Step 5: Shred the Squash
Once the spaghetti squash is cool enough to handle, use a fork to shred the flesh into noodle-like strands. Keep shredding until you’ve created a generous amount of “spaghetti.” This will serve as the base for your Keto Low Carb Steak Gorgonzola Alfredo dish.
Step 6: Combine Ingredients
In a large mixing bowl, combine the sliced steak, thawed and drained spinach, sundried tomatoes, and 4 ounces of Gorgonzola crumbles. Add a generous portion of the prepared Alfredo sauce to the mixture, stirring gently to ensure the ingredients are well-coated and evenly mixed.
Step 7: Fill and Bake
Spoon the steak and vegetable mixture back into each roasted spaghetti squash half, creating a hearty filling. Top each filled squash with 1 cup of grated mozzarella cheese, ensuring even coverage. Place the stuffed squash halves back in the oven and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
Step 8: Optional Broil and Serve
For an extra touch, switch to the broiler for 2-3 minutes towards the end of baking to achieve a beautifully browned top. Once done, remove from the oven and let cool slightly before serving. This Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash is best enjoyed warm with additional Alfredo sauce drizzled on top, if desired.
