Introduction
This Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash is a flavorful and satisfying dish that combines tender steak, creamy alfredo sauce, and the unique texture of spaghetti squash. It’s perfect for those following a low-carb or ketogenic diet who want a comforting yet healthy meal.

Ingredients
- 1 spaghetti squash (2-3 pounds)
- 1 pound steak
- Salt
- Black pepper
- Vegetable oil
- 3/4 cup frozen spinach (chopped, thawed, drained or 1.5 cups fresh chopped spinach)
- 1/4 cup sundried tomatoes (chopped or sliced)
- 4 ounces gorgonzola crumbles (or blue cheese, about 3/4 cup)
- 1 cup mozzarella cheese (grated)
- 8 tablespoons unsalted butter (1 stick, 1/4 pound)
- 2 cups heavy cream
- 1/4 teaspoon ground nutmeg
- 1 1/2 cups freshly grated Parmesan cheese
Instructions
- Step 1: Preheat the oven to 400°F (200°C).
- Step 2: Carefully cut the spaghetti squash in half lengthwise. Use towels to stabilize the squash if needed.
- Step 3: Scoop out the seeds from the inside of each half using a spoon.
- Step 4: Drizzle vegetable oil inside each half and season with salt and black pepper.
- Step 5: Place the squash halves cut side down on a baking sheet and roast for 30-40 minutes until tender when pierced with a knife. Remove from the oven and let cool slightly.
- Step 6: While the squash roasts, season the steak with salt and pepper and cook in a skillet over medium heat until just before your preferred doneness; it will finish cooking later in the oven.
- Step 7: In a medium saucepan over medium heat, melt the butter and add heavy cream. Stir in ground nutmeg once the butter has melted.
- Step 8: Remove the sauce from heat, stir in the Parmesan cheese until melted, and season with salt and pepper to taste. Set the sauce aside.
- Step 9: Use a fork to shred the inside of the roasted squash into noodle-like strands.
- Step 10: Slice the cooked steak. Add the steak, spinach, sundried tomatoes, gorgonzola crumbles, and 1/2 cup of the alfredo sauce to each squash half. Mix gently with a fork to combine. Adjust ingredients as desired.
- Step 11: Sprinkle mozzarella cheese evenly over the top of each squash half. Bake for about 15 minutes until the cheese melts. For browned cheese, briefly broil—watch carefully to avoid burning.
- Step 12: Drizzle with remaining sauce or additional garnishes if desired and serve immediately.
Tips & Variations
- Use leftover steak or substitute with cooked chicken for a different protein option.
- Fresh spinach can be sautéed briefly instead of using frozen to reduce moisture.
- Adjust the amount of gorgonzola to taste—more for stronger flavor, less for a milder cheese presence.
- Try adding garlic or herbs like thyme to the alfredo sauce for extra depth.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to avoid separating the sauce. You can also freeze portions for longer storage; thaw overnight and reheat thoroughly before serving.

FAQs
Can I use a different type of cheese instead of gorgonzola?
Yes, blue cheese works well as a substitute or you can use a milder cheese like feta if you prefer less sharpness.
How do I know when the spaghetti squash is done roasting?
The squash is ready when a knife pierces the flesh easily and the interior strings separate easily when shredded with a fork.

- Black pepper, to taste
Additional Ingredients
- 3/4 cup frozen spinach (chopped, thawed, drained or 1.5 cups fresh chopped spinach)
- 1/4 cup sundried tomatoes (chopped or sliced)
- 4 ounces gorgonzola crumbles (approximately 3/4 cup, can substitute blue cheese)
- 1 cup mozzarella cheese (grated)
Instructions
- Preheat Oven: Preheat your oven to 400°F to prepare for roasting the spaghetti squash.
- Prepare Spaghetti Squash: Carefully cut the spaghetti squash in half lengthwise. Use towels for stability if needed as it is tough to cut through.
- Remove Seeds: Scoop out the seeds from each half using a spoon.
- Season Squash: Drizzle the inside of each half with vegetable oil and sprinkle with salt and black pepper to taste.
- Roast Squash: Place the squash halves cut side down on a baking sheet. Roast for 30-40 minutes until tender when pierced with a knife. Remove from oven and let cool slightly.
- Cook Steak: While the squash roasts, season steak with salt and pepper. Cook the steak in a large skillet over medium heat until just shy of your preferred doneness, as it will cook more later in the oven.
- Make Alfredo Sauce: In a medium saucepan, melt butter over medium heat. Add heavy cream and heat until combined. Stir in ground nutmeg.
- Finish Sauce: Remove from heat, then stir in freshly grated Parmesan cheese until melted smoothly. Season with salt and pepper to taste. Set the sauce aside.
- Shred Squash: Using a fork, fluff and shred the cooked interior of each squash half to create ‘noodles’.
- Combine Fillings: Slice the cooked steak. In each squash half, add steak slices, spinach, sundried tomatoes, gorgonzola crumbles, and 1/2 cup of Alfredo sauce. Mix gently with a fork to combine well, adding more sauce or ingredients as desired.
- Add Mozzarella and Bake: Sprinkle grated mozzarella evenly over the top of each stuffed squash half. Bake at 400°F for about 15 minutes until the cheese is melted and bubbly. For browned cheese, briefly broil at the end, watching carefully to prevent burning.
- Serve: Optionally drizzle with extra Alfredo sauce or additional sundried tomatoes. Serve immediately while warm and cheesy.
Notes
- Be careful when cutting the spaghetti squash; use a sturdy knife and stabilize with a towel.
- Steak can be cooked ahead or leftover steak can be used to save time.
- Frozen spinach should be thawed and well-drained to prevent excess moisture.
- Adjust salt cautiously in the Alfredo sauce as Parmesan and gorgonzola can be quite salty.
- Broiling to brown the cheese is optional but adds a nice finish.
- This dish is naturally gluten-free and low-carb, ideal for ketogenic diets.
