Ingredients

Scale

Spaghetti Squash

  • 1 spaghetti squash

Sautéed Onion Mixture

  • 1/4 cup chopped onion
  • 2 tablespoons butter

Other Ingredients

  • 1/3 cup sour cream
  • Salt & pepper to taste
  • 2 cups grated Monterey Jack cheese, divided
  • Paprika (smoked paprika recommended) for sprinkling

Instructions

  1. Prepare the Spaghetti Squash: Cut the spaghetti squash in half lengthwise and remove the seeds. Place each half face down in a microwave-safe dish with about 1/4 inch of water. Cover with wax paper and microwave on high for 14 to 16 minutes until tender. Let cool for about 5 minutes, then use a fork to scrape out the strands of squash into a medium bowl; set aside.
  2. Sauté the Onions: While the squash cooks, melt the butter in a small skillet over medium heat. Add the chopped onion and sauté until soft and translucent, about 5 minutes.
  3. Combine Ingredients: To the bowl with the cooked spaghetti squash strands, add the sautéed onion, sour cream, salt, pepper, and 1 cup of the grated Monterey Jack cheese. Mix everything well until evenly combined.
  4. Assemble and Bake: Butter a casserole dish or large pie plate. Transfer the squash mixture into the dish and spread evenly. Sprinkle the remaining 1 cup of shredded cheese on top, then dust with paprika for extra flavor and color. Bake in a preheated oven at 325°F (163°C) for 20 minutes until the cheese is melted and slightly golden.

Notes

  • Microwaving the spaghetti squash is a quick and easy alternative to roasting it in the oven.
  • Using smoked paprika adds a nice smoky depth to the finished dish, but regular paprika works well too.
  • You can substitute sour cream with Greek yogurt for a tangier taste and to reduce fat content.
  • This recipe serves as a great low-carb, gluten-free side or main dish.
  • Adjust salt and pepper according to your taste preferences.
