  • 1 lb ground beef
  • 1 tbsp olive oil
  • 1 small onion, diced
  • 2 cloves garlic, minced

  • 1 ½ cups shredded cheddar cheese (or a mix of your favorite cheeses)
  • 1 tsp Italian seasoning
  • ½ tsp paprika
  • Salt and pepper to taste

Step-by-Step Directions

  1. Preheat the Oven: Start by preheating your oven to 400°F (200°C).

  3. Cook the Ground Beef: While the squash is baking, heat olive oil in a skillet over medium heat. Add the diced onion and minced garlic, sautéing until softened. Add the ground beef, breaking it apart with a spoon, and cook until browned. Drain any excess fat.
  4. Mix the Creamy Sauce: In a bowl, combine the sour cream, cream cheese, Italian seasoning, paprika, salt, and pepper. Mix until smooth.
  5. Shred the Squash: Once the spaghetti squash is done, use a fork to scrape out the strands into a large mixing bowl.
  6. Combine Ingredients: Add the cooked ground beef, creamy sauce, and half of the shredded cheese to the spaghetti squash. Mix well to combine.
  7. Assemble the Casserole: Transfer the mixture to a greased baking dish. Top with the remaining shredded cheese.
  8. Bake: Bake in the oven at 375°F (190°C) for 20-25 minutes, or until the cheese is melted and bubbly.
  9. Garnish and Serve: Remove from the oven and let it cool for 5 minutes. Garnish with fresh parsley or chives if desired. Serve warm and enjoy!
