Steak Gorgonzola Alfredo Ingredients
For the Spaghetti Squash
• Spaghetti Squash – A great low-carb alternative that mimics traditional pasta.
For the Steak
• Steak (1 pound) – Choose any cut you love; leftover cooked steak is a convenient time-saver.
For the Seasoning
• Salt & Black Pepper – Essential for enhancing flavors; adjust according to your palate.
• Vegetable Oil – Use for roasting; olive oil makes a healthier choice.
For the Vegetables
• Frozen Spinach (3/4 cup, thawed and drained) or Fresh Spinach (1.5 cups) – Adds vibrant color and nutrition; fresh spinach offers a different texture.
• Sundried Tomatoes (1/4 cup) – Bring a hint of sweetness and acidity; feel free to omit if preferred.
For the Alfredo Sauce
• Unsalted Butter (8 Tablespoons) – Forms the creamy base of the sauce; swap for a dairy-free substitute if needed.
• Heavy Cream (2 cups) – Adds richness to the sauce; coconut cream is a suitable non-dairy alternative.
• Ground Nutmeg (1/4 teaspoon) – A pinch adds depth; leave it out if it’s not your thing.
• Gorgonzola Cheese Crumbles (4 ounces) – Provides a bold, tangy flavor; feta works for a milder taste.
• Parmesan Cheese (1.5 cups, grated) – Enhances the sauce with salty goodness; nutritional yeast can replace it for a vegan option.
For Topping
• Mozzarella Cheese (1 cup, grated) – Adds that melty, gooey texture; a dairy-free version can work as well.

Step‑by‑Step Instructions for Steak Gorgonzola Alfredo Spaghetti Squash
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is essential for roasting the spaghetti squash to perfection. While the oven heats up, gather your baking sheet and prepare for the next steps. Preheating ensures that when you place the squash inside, it will cook evenly and achieve that tender texture you’re looking for.
Step 2: Prepare the Spaghetti Squash
Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds with a spoon. Drizzle the cut sides with vegetable oil, then sprinkle with salt and black pepper to enhance the flavor. Place the halves cut side down on a baking sheet and roast them in the preheated oven for 30-40 minutes, until the squash is fork-tender and easily shreds into spaghetti-like strands, creating a wonderful base for your Steak Gorgonzola Alfredo.
Step 3: Cook the Steak
While the squash is roasting, heat a skillet over medium heat and season your steak generously with salt and black pepper. Add a touch of oil to the hot skillet, then cook the steak for about 4-5 minutes per side to achieve your desired doneness. Once cooked, remove the steak from the skillet and let it rest for a few minutes before slicing it into thin strips, ensuring the juices remain locked in for a juicy bite.
Step 4: Make the Alfredo Sauce
In a medium saucepan, melt the unsalted butter over low heat. Once melted, slowly stir in the heavy cream, allowing it to combine and heat up gently. Add a pinch of ground nutmeg for extra depth, and after a few minutes of simmering, remove the sauce from the heat. Gradually mix in the grated Parmesan cheese until completely melted, forming a rich and creamy Alfredo sauce perfect for your Steak Gorgonzola Alfredo Spaghetti Squash.
Step 5: Fluff the Squash
After removing the spaghetti squash from the oven, let it cool for a few minutes. Using a fork, gently fluff the insides of each squash half, making strands that resemble noodles. This step creates the perfect texture to hold the creamy Alfredo sauce, steak, and other ingredients. Prepare your delicious “noodles” for the next step as you combine them with the flavorful elements of the dish.
Step 6: Combine Ingredients
In each fluffed spaghetti squash half, combine the sliced steak, thawed and drained spinach, sundried tomatoes, and half a cup of the prepared Alfredo sauce. Mix everything well, allowing the flavors to meld and coat the strands of squash, creating an inviting, vibrant filling representing the heart of your Steak Gorgonzola Alfredo.
Step 7: Add Toppings and Bake
Top each filled spaghetti squash half generously with the grated mozzarella cheese, adding that melty layer of goodness. Return the squash halves to the oven and bake for an additional 15 minutes. For a beautiful, golden-brown top, you can also broil briefly at the end of baking, keeping a close eye to avoid burning and ensure a delightful finish.
Step 8: Serve & Enjoy
Once the tops are bubbly and golden, carefully remove the Steak Gorgonzola Alfredo Spaghetti Squash from the oven. Serve hot with a drizzle of the remaining Alfredo sauce if desired, allowing everyone to enjoy the creamy decadence. This hearty, low-carb dish is a fantastic way to indulge without the guilt, perfect for a comforting dinner any night of the week!

Expert Tips for Steak Gorgonzola Alfredo
-
Properly Scrape Squash: Ensure you scrape the spaghetti squash thoroughly for adequate “noodles.” Failing to do so may leave you with an unsatisfying texture.
-
Sauce Freshness: The Alfredo sauce is best served freshly made; however, components can be prepped in advance, saving you time on busy evenings.
-
Cooking Steak: For perfectly cooked steak, aim for just below your desired doneness, as it will continue to cook slightly after being removed from heat.
-
Cheese Substitutes: If you’re not a fan of gorgonzola, feel free to swap it with feta or simply omit it altogether for a milder flavor in the Steak Gorgonzola Alfredo.
-
Adding More Veggies: Experiment by incorporating additional vegetables like bell peppers or mushrooms. This not only adds flavor but also boosts the nutritional profile of the dish.

Steak Gorgonzola Alfredo Recipe FAQs
What kind of spaghetti squash should I use?
Absolutely! Look for a spaghetti squash that feels heavy for its size and has a firm, smooth shell without blemishes or soft spots. The more yellow the skin, the riper it is, indicating sweeter flesh inside. Pairing this quality squash with your Steak Gorgonzola Alfredo will elevate your dish’s flavor and texture.
How do I store leftovers?
To keep your leftovers fresh, store them in an airtight container in the fridge for up to 3 days. I recommend separating the steak from the sauce and spaghetti squash to maintain the best texture. This way, when you’re ready to dig in again, it will taste just as heavenly!
Can I freeze the assembled Steak Gorgonzola Alfredo?
Yes, indeed! You can freeze the assembled dish for up to 2 months. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. When you’re ready to enjoy it, thaw it in the fridge overnight, then reheat in a 350°F (175°C) oven until warmed through. This method will help preserve the lovely textures, making it just as delicious on the second go.
What if I don’t like gorgonzola cheese?
Very good question! If gorgonzola isn’t your favorite, you can easily swap it for feta cheese, which offers a milder flavor without sacrificing creaminess. Alternatively, you can omit the cheese entirely, depending on your dietary preferences, and still enjoy a delightful Steak Gorgonzola Alfredo.
How should I reheat my dish?
When reheating, I suggest avoiding the microwave to maintain the delicate texture of the spaghetti squash and sauce. Instead, reheat in a 350°F (175°C) oven until thoroughly warmed, which usually takes about 15-20 minutes. This ensures that each bite remains enjoyable and well-textured, just like the first time!
