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 is perfect for roasting the spaghetti squash, making it tender and easy to fluff into noodles later. Set aside a large baking sheet to catch any drippings from the squash as it cooks.
Step 2: Prepare the Spaghetti Squash
Carefully cut the spaghetti squash in half lengthwise, scooping out the seeds with a spoon. Drizzle the cut sides generously with vegetable oil, then sprinkle with salt and pepper to enhance flavor. Place the squash halves cut-side down on the baking sheet and roast in the preheated oven for 30-40 minutes, or until the skin is easily pierced with a fork.
Step 3: Cook the Steak
While the spaghetti squash is roasting, season your steak with salt and black pepper. Heat a skillet over medium-high heat and add a splash of oil. Sear the steak for about 3-4 minutes per side, cooking until it’s just shy of your preferred doneness. Remember, it will continue cooking in the oven later, so aim for medium-rare to medium. Remove the steak and let it rest.
Step 4: Make the Alfredo Sauce
In a saucepan over medium heat, melt the unsalted butter, followed by heavy cream. Stir continuously until the mixture is warmed through and begins to simmer. Gently add the ground nutmeg, then whisk in the Parmesan cheese until the sauce is creamy and smooth. Taste and adjust seasoning with salt and pepper as desired, letting the sauce simmer on low while you prepare the other ingredients.
Step 5: Fluff the Squash
Once the roasted spaghetti squash is cool enough to handle, use a fork to fluff the insides, creating long, noodle-like strands. This is where the magic happens—the squash transforms into a fantastic keto-friendly base for your Steak Gorgonzola Alfredo.
Step 6: Combine the Ingredients
In a large mixing bowl, combine the sliced steak, drained spinach, sundried tomatoes, gorgonzola, and about ½ cup of the prepared Alfredo sauce. Gently mix everything until well incorporated; the flavors meld beautifully together, creating a rich filling that will pair perfectly with the spaghetti squash.
Step 7: Assemble and Bake
Spoon the steak mixture evenly into the hollows of the spaghetti squash halves. Top generously with grated mozzarella cheese, ensuring an even layer covers each half. Place the filled squash back on the baking sheet and return to the oven for an additional 15 minutes, or until the cheese is melted and bubbly. Consider broiling for a couple of minutes at the end for that perfect golden finish.
Step 8: Serve and Enjoy
Once out of the oven, allow the dish to cool slightly before serving. Serve warm, drizzling with extra Alfredo sauce if desired, and feel free to garnish with additional gorgonzola or fresh herbs. This Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash is sure to impress your family and friends!

Expert Tips for Steak Gorgonzola Alfredo Spaghetti Squash
-
Perfect Cut: Always use a safe cutting method for spaghetti squash. If it’s too hard to cut, microwave it for 6 minutes to soften.
-
Don’t Overcook: Keep an eye on your steak while cooking. Aim for medium-rare, as it will continue cooking in the oven when you bake the filled squash.
