Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash Ingredients
• Dive into the deliciousness with these must-have ingredients!
For the Spaghetti Squash
- Spaghetti Squash – Acts as a low-carb pasta substitute; choose one weighing 2-3 pounds for the perfect base.
- Vegetable Oil – Helps achieve that lovely roast; olive oil can work as a fantastic alternative.
For the Filling
- Steak – Provides a rich, protein-packed flavor; any cut works, or feel free to use leftover steak.
- Frozen Spinach (thawed and drained) – Adds nutrition and vibrant color; fresh spinach can be used instead (about 1.5 cups).
- Sundried Tomatoes – Delivers a burst of flavor; slice or chop them to your liking.
- Gorgonzola Crumbles (or Blue Cheese) – Introduces a tangy, creamy element; swap for feta if you prefer a milder taste.
For the Alfredo Sauce

- Freshly Grated Parmesan Cheese – Gives a savory flavor and thickens the sauce beautifully; it’s essential for that authentic taste.

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). Preparing the oven ahead of time ensures that your spaghetti squash will roast evenly and thoroughly, resulting in tender “noodles.” This key step gets you one step closer to enjoying the rich flavors of your Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash.
Step 2: Prepare the Spaghetti Squash
Carefully cut the spaghetti squash in half lengthwise, removing the seeds with a spoon. Drizzle the cut sides with vegetable oil, seasoning with salt and black pepper to taste. This seasoning enhances the natural flavors, setting the stage for the roasting process.
Step 3: Roast the Squash
Place the prepared squash halves, cut side down, on a baking sheet lined with parchment paper. Roast in your preheated oven for 30 to 40 minutes, until the flesh is fork-tender and easily shreds into spaghetti-like strands. The golden hue will signal that your squash is ready for the next steps.
Step 4: Cook the Steak
While the squash is roasting, heat a skillet over medium heat and add your steak cut of choice. Season with salt and black pepper, cooking for about 4–6 minutes per side until it reaches your desired doneness. Remove from heat, let it rest briefly, then slice it into thin strips for the filling.
Step 5: Make the Alfredo Sauce
In a medium saucepan, melt unsalted butter over medium heat. Once melted, pour in heavy cream and stir gently until combined. Add a pinch of ground nutmeg and freshly grated Parmesan cheese, stirring until the sauce thickens slightly and becomes creamy. Taste and season, allowing the alfredo sauce to meld beautifully.
Step 6: Fluff the Spaghetti Squash
Once roasted, carefully flip the spaghetti squash halves cut side up. Use a fork to fluff the interior, creating those lovely “noodles”. This texture mimics traditional pasta and perfectly holds the creamy sauce, ensuring your Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash delivers on every flavor note.
Step 7: Combine the Fillings
In a mixing bowl, combine the sliced steak, thawed spinach, sundried tomatoes, and gorgonzola crumbles. Reserve ½ cup of your prepared Alfredo sauce, mixing the rest with your steak mixture until well incorporated. This hearty filling is where the magic happens, bursting with flavor and color.
Step 8: Assemble and Bake
Spoon the steak and vegetable mixture generously into each squash half, topping with grated mozzarella cheese for that perfect melt. Place the filled squash back in the oven and bake for an additional 15 minutes until the cheese is bubbly and golden brown. A little browning on top adds to the dish’s allure!
Step 9: Serve and Enjoy
Once baked, remove the Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash from the oven. Drizzle any leftover alfredo sauce over the top if desired for added richness. Serve immediately, allowing the amazing aromas and flavors to entice your family and friends as you present this mouthwatering dish!

Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash Recipe FAQs
What is the best way to select a ripe spaghetti squash?
Absolutely! When choosing a spaghetti squash, look for one that’s heavy for its size with a firm skin and no dark spots. The skin should have a slight sheen, and the ends should be intact—not shriveled. A ripe squash can withstand a gentle squeeze without yielding too much, signaling its freshness.

To keep your leftovers fresh, store them in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy them again, reheating in the microwave is convenient.

What should I do if my alfredo sauce is too thick?
Very common! If your alfredo sauce turns out too thick, simply add a small amount of milk, half-and-half, or broth, stirring until you reach the desired consistency.
