The image shows a close-up of a stuffed, halved golden-yellow roasted squash on a white plate, resting on a white marbled surface. The squash is filled with a layered mixture: the base is soft, creamy white rice, sprinkled with bright green chopped herbs. On top, there are pieces of dark green cooked kale and small chunks of deep brown meat. White crumbled cheese is spread generously, with some reddish-brown sun-dried tomatoes scattered throughout. A shiny silver fork held by a woman's hand scoops a mix of rice, meat, and cheese from one half.

Ingredients

  • 1 spaghetti squash (2-3 pounds)
  • 1 pound steak
  • Salt
  • Black pepper
  • Vegetable oil
  • 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 (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

  1. Step 1: Preheat your oven to 400°F (200°C). Carefully cut the spaghetti squash in half lengthwise on a stable surface. Remove the seeds with a spoon.
  2. Step 2: Drizzle the inside of each squash half with vegetable oil and season with salt and black pepper. Place squash cut side down on a baking sheet and roast for 30-40 minutes until tender when pierced with a knife. Let cool slightly.
  3. Step 3: While the squash roasts, season the steak with salt and black pepper. Cook it in a large skillet over medium heat until just before your preferred doneness; it will finish cooking in the oven. Remove from heat and slice.
  4. Step 4: Prepare the alfredo sauce: In a medium saucepan, melt butter over medium heat. Add heavy cream and heat until warm. Stir in ground nutmeg, then remove from heat and mix in Parmesan cheese until melted and smooth. Season with salt and black pepper to taste.
  5. Step 5: Use a fork to shred the flesh inside the spaghetti squash halves into strands, creating the “noodles.”
  6. Step 6: Add sliced steak, chopped spinach, sundried tomatoes, gorgonzola crumbles, and half of the alfredo sauce into each squash half. Mix gently with a fork to combine all ingredients evenly.
  7. Step 7: Sprinkle mozzarella cheese over the top of each filled squash.
  8. Step 8: Bake the squash boats for about 15 minutes, until the cheese melts. For a browned top, briefly broil—watch carefully to avoid burning.
  9. Step 9: Drizzle with additional alfredo sauce or extra sundried tomatoes if desired and serve immediately.

Tips & Variations

  • You can use any cut of steak you prefer or substitute with leftover cooked steak for convenience.
  • Fresh Alfredo sauce is best, but you can prepare the squash and other fillings ahead of time to save cooking day effort.
  • For a dairy-free version, try a Whole30 compliant non-dairy Alfredo sauce and omit the cheese.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to avoid curdling the sauce. The alfredo sauce is best freshly made, but the squash and meat components reheat well.

How to Serve

Inside, there is a white creamy cheese layer mixed with small green herbs and pieces of dark brown sun-dried tomatoes scattered on top. The stuffed vegetable is placed on a bed of fresh green leafy vegetables. A silver fork held by a woman's hand is lifting a portion, showing the creamy texture mixed with darker bits of vegetable and herbs. The background is a white marbled texture.

Scale

  • 1 pound steak (your choice of cut)

  • Black pepper, to taste
  • Vegetable oil, for drizzling

Filling

  • 3/4 cup frozen spinach, chopped, thawed and drained (or 1.5 cups fresh chopped spinach)

  • 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

  1. Preheat the oven: Preheat your oven to 400°F (200°C) to prepare for roasting the spaghetti squash.
  2. Prepare spaghetti squash: Carefully cut the spaghetti squash in half lengthwise, using towels to stabilize it if needed. Scoop out the seeds from each half with a spoon.
  3. Season squash: Drizzle vegetable oil inside the squash halves and season with salt and pepper. Place the squash cut side down on a baking sheet.
  4. Roast squash: Roast the squash in the preheated oven for about 30-40 minutes, or until tender when pierced with a knife. Remove and allow to cool slightly.
  5. Cook steak: While the squash roasts, season the steak with salt and pepper. Cook it in a large skillet over medium heat slightly under your preferred doneness, as it will finish cooking in the oven.
  6. Make Alfredo sauce: In a medium saucepan, melt the butter over medium heat. Add heavy cream and ground nutmeg, stirring to combine. Remove from heat and stir in Parmesan cheese until melted. Season the sauce with salt and pepper to taste.
  7. Shred spaghetti squash: Use a fork to scrape the flesh of the roasted squash to create ‘noodles’.
  8. Assemble filling: Slice the cooked steak. In each squash half, combine the steak slices, spinach, sundried tomatoes, gorgonzola crumbles, and 1/2 cup Alfredo sauce, mixing gently with a fork.
  9. Add cheese topping: Sprinkle grated mozzarella evenly over the stuffed squash halves.
  10. Bake to melt cheese: Bake the squash boats in the oven for about 15 minutes until the mozzarella is melted and bubbly. For browned cheese, briefly broil after baking, ensuring no parchment or silicone is under the squash.
  11. Serve: Optionally drizzle extra Alfredo sauce or add more sundried tomatoes as garnish. Serve immediately while hot.

Notes

  • Any steak cut works well—use your favorite or leftovers (about 3/4 pound cooked steak yields similar portion).
  • The Alfredo sauce is best made fresh, but the rest of the components can be prepared ahead of time.
  • If desired, use fresh spinach instead of frozen for a brighter flavor.
  • You can substitute blue cheese if Gorgonzola is unavailable.
