Ingredients (Serving Size: 4-6 People):
- 2 medium spaghetti squashes
- 2 tablespoons olive oil
- Salt and pepper to taste
- 1 pound boneless, skinless chicken breasts
- 3 cloves garlic, minced
- 1 cup heavy cream
- 1 cup grated Parmesan cheese
- 1 teaspoon Italian seasoning
- 1 cup shredded mozzarella cheese
- Fresh parsley, chopped (optional, for garnish)
Cooking Instructions:
1. Prepare the Spaghetti Squash: Preheat your oven to 400°F (200°C). Slice each spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil and season with salt and pepper.
Place the squash halves cut-side down on a baking sheet and roast for 30-40 minutes, or until the flesh is tender and easily separates into strands with a fork.
2. Cook the Chicken: While the squash is roasting, heat a tablespoon of olive oil in a large skillet over medium heat. Season the chicken breasts with salt and pepper, then add them to the skillet.
Cook for about 6-7 minutes on each side, or until fully cooked and no longer pink inside. Remove from the skillet and let cool slightly before shredding or cubing the chicken.
3. Prepare the Alfredo Sauce: In the same skillet, add the minced garlic and sauté for 1-2 minutes until fragrant. Pour in the heavy cream, stirring constantly, and bring to a gentle simmer.
Stir in the Parmesan cheese and Italian seasoning until the cheese is fully melted and the sauce is smooth. Adjust seasoning with additional salt and pepper if needed.
4. Assemble the Casserole: Reduce the oven temperature to 375°F (190°C). Using a fork, scrape the roasted spaghetti squash into strands and transfer to a large mixing bowl.
Add the shredded chicken and Alfredo sauce to the bowl, mixing until well combined. Transfer the mixture into a greased 9×13-inch baking dish.
5. Bake the Casserole: Sprinkle the shredded mozzarella cheese evenly over the top of the casserole. Bake in the preheated oven for 20-25 minutes, or until the cheese is golden and bubbly.
Remove from the oven and let rest for a few minutes before serving.
6. Garnish and Serve: If desired, sprinkle freshly chopped parsley over the top for a burst of color and flavor. Serve hot and enjoy!
Extra Tips:
To guarantee your spaghetti squash strands are perfectly tender, check them with a fork after 30 minutes of roasting. If they don’t easily pull away from the skin, continue cooking in 5-minute increments.
For added flavor, feel free to incorporate additional herbs like thyme or basil into the Alfredo sauce. You can also use pre-cooked rotisserie chicken to save time, simply shred and add to the casserole.
If you’re looking to add more vegetables, consider mixing in some steamed broccoli or spinach for a nutritious boost.

Ingredients for 4-6 people:
- 1 large spaghetti squash
- 2 tablespoons olive oil
- 1 pound mushrooms, sliced
- 3 cloves garlic, minced
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1 teaspoon dried oregano
- Salt and pepper to taste
- 1 cup heavy cream
- 1 cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- Fresh parsley, chopped (for garnish)
Cooking Instructions:
- Prepare the Spaghetti Squash: Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise and remove the seeds. Drizzle with olive oil and season with salt and pepper. Place the squash halves cut side down on a baking sheet and roast for 30-40 minutes, or until the flesh is tender and easily shredded with a fork.
- Cook the Mushrooms: While the squash is roasting, heat the remaining olive oil in a large skillet over medium heat. Add the sliced mushrooms and cook until they’re golden brown and have released their moisture, about 8-10 minutes.
- Add Garlic and Herbs: Stir in the minced garlic, thyme, rosemary, and oregano into the mushrooms. Cook for another 2 minutes, until the garlic is fragrant.
- Combine Cream and Cheese: Pour in the heavy cream and bring to a gentle simmer. Stir in the Parmesan cheese until it melts and thickens the sauce slightly. Season with salt and pepper to taste.
- Assemble the Casserole: Once the spaghetti squash is done, use a fork to scrape the flesh into strands and add them to the skillet with the mushroom mixture. Toss everything together until well combined.
- Bake the Casserole: Transfer the mixture to a greased casserole dish. Sprinkle the shredded mozzarella cheese evenly over the top. Bake in the preheated oven for 15-20 minutes, or until the cheese is bubbly and golden brown.
- Garnish and Serve: Remove from the oven and let the casserole cool slightly. Garnish with fresh parsley before serving.
Extra Tips:
For an added depth of flavor, consider using a mix of different mushroom varieties, such as cremini, shiitake, and portobello. Be sure to roast the spaghetti squash until it’s perfectly tender; undercooked squash can be stringy and less enjoyable.
If you prefer a spicier dish, add a pinch of red pepper flakes when cooking the mushrooms. Finally, this casserole can be prepared a day in advance; simply assemble and refrigerate it, then bake just before serving.

Once these components are ready, the casserole is assembled and baked until bubbling and golden brown. This recipe serves 4-6 people, making it an ideal choice for family dinners or meal prep for the week.
Ingredients:
- 2 medium spaghetti squashes
- 2 tablespoons olive oil
- Salt and pepper to taste
- 1 pound ground beef
- 1 onion, finely chopped
- 3 cloves garlic, minced
- 1 can (28 ounces) crushed tomatoes
- 2 tablespoons tomato paste
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon red pepper flakes (optional)
- 1/2 cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- Fresh parsley, chopped (for garnish)
Cooking Instructions:
1. Prepare the Spaghetti Squash: Preheat your oven to 400°F (200°C). Cut the spaghetti squashes in half lengthwise and scoop out the seeds. Drizzle the inside of each squash with olive oil, then season with salt and pepper.
Place them cut side down on a baking sheet and roast for about 35-45 minutes, or until the flesh is tender and easily shredded with a fork. Once done, remove from the oven and let them cool slightly.
2. Make the Bolognese Sauce: While the squash is roasting, heat a large skillet over medium heat and add the ground beef. Cook until browned, breaking it into crumbles with a spatula. Drain excess fat if necessary.
Add the chopped onion and minced garlic to the skillet and sauté until the onion becomes translucent. Stir in the crushed tomatoes, tomato paste, oregano, basil, and red pepper flakes. Let the sauce simmer for 15-20 minutes, allowing the flavors to meld together. Season with salt and pepper to taste.
3. Assemble the Casserole: Once the spaghetti squash is cool enough to handle, use a fork to scrape out the strands into a large mixing bowl. Add the prepared Bolognese sauce to the bowl and mix until the squash is well coated.
Transfer the mixture into a greased baking dish. Sprinkle the top with grated Parmesan cheese and shredded mozzarella cheese.
4. Bake the Casserole: Reduce the oven temperature to 375°F (190°C). Place the assembled casserole in the oven and bake for 20-25 minutes, or until the cheese is melted and bubbly.
For a golden top, switch the oven to broil for the last 3-5 minutes of cooking, keeping a close eye to prevent burning.
5. Serve and Garnish: Remove the casserole from the oven and let it cool for a few minutes before serving. Garnish with freshly chopped parsley for a burst of color and added flavor.
Extra Tips:
When selecting spaghetti squash, look for ones that are firm and free of soft spots, which indicates freshness. To make the squash easier to cut, you can microwave it for a few minutes to soften the rind slightly.
If you prefer a spicier casserole, increase the amount of red pepper flakes in the Bolognese sauce. For added depth of flavor, try incorporating a splash of red wine into the sauce while it simmers.
This dish can be stored in an airtight container in the refrigerator for up to 3 days, making it a great option for leftovers or meal prep.
