How to Make Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash
-
Preheat your oven to 400°F. Carefully cut the spaghetti squash in half and scoop out the seeds to prepare it for roasting. This step sets the foundation for a perfectly tender base!
-
Drizzle vegetable oil over the cut sides, then season generously with salt and black pepper. Place the squash cut side down on a baking sheet and roast for about 30-40 minutes, or until it’s fork-tender and easily shredded into spaghetti-like strands.
-
Cook the steak meanwhile! Season it to your liking and use a skillet to cook it until it reaches just shy of your desired doneness. This ensures it will remain juicy and tender in the final dish.
-
Combine the base for the Alfredo sauce by melting unsalted butter in a saucepan over medium heat. Slowly add heavy cream, ground nutmeg, and allow it to heat through while stirring continuously until it’s smooth and creamy. Mix in freshly grated Parmesan cheese until fully incorporated. Set aside!
-
Shred the spaghetti squash once it’s cooked. Take a fork and gently scrape the insides to create your “noodles.”
-
Mix the squash noodles with sliced steak, thawed frozen spinach, chopped sundried tomatoes, and gorgonzola cheese. Add in about ½ cup of your delicious Alfredo sauce and stir until everything is coated evenly.
-
Top each half of the spaghetti squash with a generous amount of mozzarella cheese. Bake again in the oven for approximately 15 minutes, or until the cheese is melted and bubbly. Broil for an additional minute if you prefer a beautifully browned topping.
-
Drizzle with leftover Alfredo sauce when serving for extra creaminess and flavor delight.
Optional: Garnish with fresh herbs like parsley for a pop of color and freshness.

Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash Recipe FAQs
What is the best way to select a spaghetti squash?
When choosing spaghetti squash, look for one that feels heavy for its size, with a hard, smooth skin. Avoid any squash with soft spots or cracks, as these can indicate overripeness. A vibrant yellow color is usually a good sign that it’s ripe and ready to cook!
How should I store leftover Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash?
Store leftover spaghetti squash in an airtight container in the refrigerator for up to 3 days. It’s best to keep the Alfredo sauce separate to prevent the noodles from becoming soggy. Just reheat them together when you’re ready to enjoy!
Can I freeze the assembled stuffed spaghetti squash?
Absolutely! To freeze, place the assembled stuffed squash into a freezer-safe container or wrap it tightly in plastic wrap and then aluminum foil. It can be frozen for up to 2 months. When ready to enjoy, thaw it overnight in the fridge before reheating.
What if my Alfredo sauce isn’t as creamy as I hoped?
If your Alfredo sauce isn’t as creamy as you’d like, consider adding more heavy cream or a touch of grated Parmesan while it’s still on the stove. Make sure you stir constantly and allow it to simmer gently for a few minutes to help it thicken up. Freshly grated Parmesan will melt more smoothly than pre-grated options!
Is this recipe suitable for people with dairy allergies?
While this recipe contains several dairy ingredients, alternatives can be used to make it dairy-free. Substitute the butter with dairy-free margarine, use coconut cream or almond milk in place of heavy cream, and try a dairy-free cheese option for the gorgonzola and mozzarella. Just be mindful of flavors and texture as dairy substitutes can change the outcome.
Can I use different vegetables instead of spinach?
Very! If spinach isn’t your favorite, consider adding kale, zucchini, or mushrooms for additional flavor and nutrition. Each vegetable will bring its unique texture and taste, enhancing your Keto Low Carb Steak Gorgonzola Alfredo Spaghetti Squash experience!
