Ingredients

  • 1 spaghetti squash
  • 1/4 cup chopped onion
  • 2 tablespoons butter
  • 1/3 cup sour cream
  • Salt & pepper to taste
  • 2 cups grated Monterey Jack cheese, divided
  • Paprika (smoked paprika recommended)

Instructions

  1. Step 1: Cut the spaghetti squash in half lengthwise and remove the seeds. Place the halves face down in a microwave-safe dish with about 1/4 inch of water. Cover with wax paper and microwave until the squash is tender, about 14 to 16 minutes. Let cool for 5 minutes, then use a fork to scrape out the strands into a medium bowl. Set aside.
  2. Step 2: While the squash cooks, melt the butter in a small skillet over medium heat. Add the chopped onion and sauté until soft and transparent, about 3 to 5 minutes.
  3. Step 3: To the bowl with the cooked squash, add the sautéed onion, sour cream, salt, pepper, and 1 cup of the grated Monterey Jack cheese. Mix everything well. Transfer the mixture into a buttered casserole dish or large pie plate. Sprinkle the remaining cheese evenly over the top and dust with paprika.
  4. Step 4: Bake in a preheated oven at 325°F (160°C) for 20 minutes, or until the cheese is melted and bubbly. Serve warm.

Tips & Variations

  • For extra flavor, try adding minced garlic when sautéing the onions.
  • Swap sour cream with Greek yogurt for a tangier, lighter option.
  • Add cooked, crumbled bacon or diced cooked chicken for a heartier dish.
  • Use regular paprika if smoked paprika isn’t available; it will still add pleasant color and mild flavor.
  • Microwave times can vary depending on squash size; check tenderness by piercing with a fork.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 325°F (160°C) until warmed through, or microwave on medium power for a couple of minutes. The texture is best enjoyed fresh but still comforting when reheated.

Cover the dish with wax paper and microwave on high for approximately 14 to 16 minutes, or until the squash is tender. Let cool for 5 minutes.

Notes

  • For a crispier topping, broil the casserole for 2-3 minutes after baking, watching carefully to prevent burning.
  • You can substitute sour cream with Greek yogurt for a tangier flavor and added protein.
  • Use fresh paprika or smoked paprika depending on your preferred flavor profile.
  • This dish pairs well with grilled chicken or a fresh green salad for a complete meal.
  • Ensure the squash is cool enough to handle before scraping the strands to avoid burns.
