Steak Gorgonzola Alfredo Spaghetti Squash Ingredients
For the Squash
• Spaghetti Squash – This serves as the perfect low carb pasta substitute; choose one weighing 2-3 pounds.
• Vegetable Oil – Drizzle for roasting, as it enhances flavor and aids in caramelization.
For the Filling
• Steak – Use your favorite cut; it adds delicious flavor and protein (approx. 3/4 pound cooked is ideal).
• Frozen Spinach (3/4 cup) or Fresh Spinach (1.5 cups) – Rich in vitamins, make sure to thaw and drain if using frozen.
• Sundried Tomatoes (1/4 cup) – These add a burst of sweetness and texture to the dish.
For the Sauce
• Unsalted Butter (8 tablespoons) – Forms the base of your creamy Alfredo; you can substitute with olive oil for a dairy-free option.
• Heavy Cream (2 cups) – Key for achieving that rich, creamy sauce; coconut cream is a great dairy-free alternative!
• Ground Nutmeg (1/4 teaspoon) – Adds depth and subtly enhances the flavors of the sauce.
• Freshly Grated Parmesan Cheese (1.5 cups) – Essential for richness; adjust to taste.
• Gorgonzola Crumbles (4 ounces or ~3/4 cup) – Provides that tangy, creamy texture; can swap with blue cheese if needed.
• Salt and Black Pepper – Always adjust to taste for seasoning.
For the Topping
• Mozzarella Cheese (1 cup, grated) – Adds a gooey, melty layer that’s irresistible.

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 step is essential as it ensures your Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash will roast evenly and become tender. A hot oven will give the spaghetti squash a beautiful caramelization, enhancing its flavor.
Step 2: Prepare the Spaghetti Squash
Carefully cut the spaghetti squash in half lengthwise using a sharp knife. Scoop out the seeds using a spoon, allowing access to the tender flesh. Drizzle a pinch of vegetable oil inside each half, then sprinkle with salt and pepper for added flavor. This step not only seasons the squash but also prepares it for roasting.
Step 3: Roast the Squash
Place the squash halves cut side down on a baking sheet lined with parchment paper. Roast in the oven for 30–40 minutes, or until the flesh is fork-tender and easily shreds into noodles. Keep an eye out for a golden-brown color on the skin, indicating it’s ready to enjoy as a low-carb pasta substitute.
Step 4: Cook the Steak
While the spaghetti squash is roasting, heat a skillet over medium heat. Season your steak with salt and pepper, then cook it for about 5–7 minutes on each side, or until it’s just shy of your desired doneness. Let it rest for a few minutes before slicing. The cooked steak will add a rich flavor to your gorgonzola Alfredo.
Step 5: Make the Alfredo Sauce
In a saucepan, melt 8 tablespoons of butter over medium heat before adding 2 cups of heavy cream. Stir gently, allowing the mixture to combine and warm through. Next, sprinkle in 1/4 teaspoon of nutmeg, which will enhance the sauce’s flavor, and remove it from heat once warmed. Mix in 1.5 cups of freshly grated Parmesan cheese until melted and smooth, seasoning with salt and pepper to taste.
Step 6: Fluff the Squash
Once the spaghetti squash is roasted and tender, use a fork to fluff the flesh, creating “noodles.” This noodle-like texture is essential for imitating traditional pasta and serves as the base for your Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash. Set aside as you prepare the filling.
Step 7: Combine the Filling
Slice the rested steak into bite-sized pieces. In a mixing bowl, combine the steak, thawed spinach, sundried tomatoes, gorgonzola crumbles, and half of the prepared Alfredo sauce. This delightful filling will bring all the flavors together, making your dish robust and satisfying.
Step 8: Assemble and Bake
Evenly divide the filling between the roasted spaghetti squash halves, then drizzle the remaining Alfredo sauce over the top. Sprinkle with 1 cup of grated mozzarella cheese, creating a cheesy layer that complements the dish beautifully. Return the halves to the oven and bake for an additional 15 minutes, or until the cheese is melted and bubbly.
Step 9: Serve and Enjoy
Once the cheese is perfectly melted and slightly golden, remove the Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash from the oven. Serve immediately, drizzling additional Alfredo sauce on top if desired. This hearty dish is sure to impress your family and friends, striking a perfect balance between comfort food and healthy eating!
