Introduction
This Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash is a delicious and satisfying meal that combines tender steak, creamy Alfredo sauce, and flavorful cheeses all served in a roasted spaghetti squash “bowl.” It’s perfect for those looking to enjoy a comforting dish without the carbs of traditional pasta.

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) (approximately 3/4 cup)
- 1 cup mozzarella cheese, grated
- Alfredo Sauce:
- 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
- Salt
- Black pepper
Instructions
- Step 1: Preheat your oven to 400°F. Carefully cut the spaghetti squash in half lengthwise, then remove the seeds by scraping the inside with a spoon. Drizzle the inside with vegetable oil and season with salt and black pepper.
- Step 2: Place the squash halves cut side down on a baking sheet and roast for 30-40 minutes, or until tender when pierced with a knife. Remove from oven and let cool slightly.
- Step 3: While the squash cooks, season the steak with salt and pepper. Cook it in a large skillet over medium heat just shy of your preferred doneness as it will finish cooking in the oven later. Set aside.
- Step 4: Make the Alfredo sauce by combining butter and heavy cream in a medium saucepan over medium heat. When butter melts, add nutmeg and stir. Remove from heat, then stir in Parmesan cheese until melted. Season with salt and pepper to taste and set aside.
- Step 5: Use a fork to fluff and shred the spaghetti squash flesh to create noodle-like strands.
- Step 6: Slice the steak thinly. In each squash half, mix the steak, spinach, sundried tomatoes, gorgonzola crumbles, and 1/2 cup of Alfredo sauce. Stir gently to combine and distribute the ingredients evenly.
- Step 7: Sprinkle mozzarella cheese on top of each squash boat. Bake for about 15 minutes until the cheese melts. For browned cheese, briefly broil the squash once the cheese is melted, being careful not to burn.
- Step 8: Drizzle additional Alfredo sauce or add extra sundried tomatoes if desired, then serve immediately.
Tips & Variations
- Use leftover cooked steak to save time and add more flavor from marinating.
- Swap gorgonzola with blue cheese or goat cheese for a different tangy taste.
- Fresh spinach can be lightly sautéed instead of using frozen for a firmer texture.
- For a creamier sauce, add a little cream cheese while making the Alfredo sauce.
- If you prefer a spicier kick, sprinkle some crushed red pepper flakes in the sauce or over the top.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or in a low oven to avoid overcooking the steak or drying out the squash. Adding a splash of cream or sauce when reheating can help keep the dish moist.

FAQs
Can I use other types of squash instead of spaghetti squash?
Spaghetti squash has a unique stringy texture that mimics noodles. Other squashes like butternut or acorn won’t create the same effect but can be roasted and used as a base if you prefer a softer texture.
Is this recipe suitable for strict keto diets?
Yes, this recipe is low in carbs and high in fat and protein, making it ideal for a keto diet. Just be sure to check the ingredients you use, especially the cheeses, to avoid added sugars or starches.

Ingredients
Spaghetti Squash and Steak
- 1 spaghetti squash (2–3 pounds)
- 1 pound steak
- Salt, to taste
- Black pepper, to taste
- 1–2 tablespoons vegetable oil
Vegetables and Cheese
- 3/4 cup frozen spinach, chopped, thawed, and drained (or 1.5 cups fresh chopped spinach)
- 1/4 cup sundried tomatoes, chopped or sliced
- 4 ounces gorgonzola crumbles (approximately 3/4 cup; blue cheese can be substituted)
- 1 cup mozzarella cheese, grated
Alfredo Sauce
- 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
- Salt, to taste
- Black pepper, to taste
Instructions
- Preheat the Oven: Preheat your oven to 400°F (200°C) to prepare for roasting the spaghetti squash.
- Prepare the Spaghetti Squash: Carefully cut the spaghetti squash in half lengthwise; use a sturdy knife and stabilize it on towels if needed. Scoop out and discard the seeds using a spoon.
- Season and Roast Squash: Drizzle the inside of each squash half with vegetable oil and sprinkle with salt and pepper. Place them cut side down on a baking sheet and roast in the oven for 30-40 minutes until the flesh is tender when pierced with a knife. Remove and let cool slightly.
- Cook the Steak: While the squash roasts, season the steak with salt and pepper. Heat a large skillet over medium heat with a bit of vegetable oil and cook the steak just below your preferred doneness since it will finish cooking in the oven. Remove and let rest.
- Make the Alfredo Sauce: In a medium saucepan, melt the butter over medium heat. Stir in the heavy cream and heat until warm. Add ground nutmeg and mix. Remove from heat, then gradually stir in the grated Parmesan cheese until melted and smooth. Season with salt and black pepper to taste.
- Shred the Squash: Once cool enough to handle, use a fork to scrape and fluff the interior flesh of each spaghetti squash half to create the distinctive spaghetti-like strands.
- Combine Ingredients: Slice the cooked steak. Add the steak slices, chopped spinach, sundried tomatoes, gorgonzola crumbles, and half a cup of Alfredo sauce into each squash half. Mix gently with a fork to combine all ingredients well. Adjust quantities to taste if desired.
- Add Cheese and Bake: Sprinkle grated mozzarella cheese evenly over the top of each stuffed squash half. Bake in the preheated oven for about 15 minutes until the cheese melts. For a browned top, broil briefly just after baking, being careful not to burn the cheese or squash.
- Serve: Drizzle with any remaining Alfredo sauce and optionally garnish with extra sundried tomatoes or cheese. Serve immediately while hot and creamy.
Notes
- Be careful when cutting the spaghetti squash; use a sharp knife and stabilize the squash to avoid injury.
- If you prefer your steak more cooked before mixing, adjust the cooking time accordingly but remember it will cook further during baking.
- Alfredo sauce saltiness varies with Parmesan cheese; season carefully to avoid over-salting.
- For a dairy-free version, substitute cheeses and cream with keto-friendly dairy-free alternatives.
- Leftover steak from previous meals works well and can save prep time.
- Broiling the cheese at the end adds a nice golden brown crust but watch closely as it can burn quickly.
