Step by step instructions
- Prepare the squash. Cut a large spaghetti squash in half lengthwise. Use a fork to remove the seeds. Then, brush the inside of each half with olive oil and season with salt and pepper.
- Roast it. Place each side of the squash cut side down on a parchment lined baking sheet. Bake in a 400°F preheated oven for 45 minutes.
- Create the ‘noodles’. Remove from the oven and carefully use a fork to pull the strands of squash from the shell.
- Note: You can also check out this guide for how to cook spaghetti squash in the microwave, oven or air fryer. If you’re short on time, the microwave is a great option to make this recipe in under 30 minutes!
- Make the cheese sauce. Add shredded part-skim mozzarella cheese, grated parmesan cheese, ricotta cheese and goat cheese to a large saucepan on the stove over medium heat. Pour milk into the saucepan and stir the cheese sauce consistently until it’s smooth and creamy.
- Finish the dish. Add the baked spaghetti squash noodles to the cheese sauce and stir to combine. Garnish with a dash of salt and pepper and fresh chopped basil, if you’d like. Serve the spaghetti squash mac and cheese in bowls or place back in the squash shells to save dishes!
Frequently asked questions
- Does this recipe make good leftovers? Yes! Leftover spaghetti squash mac and cheese is still totally delicious the second time around. Store it in an airtight container in the refrigerator for up to 5 days, then use one of the methods below to reheat it before eating.
- Can you reheat it? Yes. To reheat it on the stove, place the mac and cheese in a medium saucepan on the stove over medium heat and stir consistently for 5-10 minutes, or until the dish is heated through. You can also place the squash in an oven safe baking dish, cover with foil, and bake in a 350°F oven for 15 minutes to reheat. Or quickly pop it in the microwave in a covered microwave safe bowl and microwave for 2 minutes.
- What is the easiest way to cut a spaghetti squash in half? I like to use an electric knife to make slicing the uncooked squash safer and easier. You can also poke a few holes in the squash along where you will be cutting and microwave it for 3-4 minutes to soften it up a bit.
I love adding veggies to this mac and cheese, especially if I’m eating it as an entree. Roasted veggies add more nutrition and texture, and you can roast them right alongside the spaghetti squash. Follow these 3 simple steps to add roasted broccoli and/or cauliflower to the dish.
- Spread the vegetables out into an even layer on a baking sheet, drizzle with olive oil, then sprinkle with salt and pepper.
- Place in the 400°F oven with the spaghetti squash for the last 20 minutes of cooking.
- Remove from the oven and add the veggies to the cheese sauce with the roasted spaghetti squash.
If you’d like to add chicken to the mac and cheese, I highly recommend checking out this Bruschetta Grilled Chicken recipe. You can use and the marinade + grilling techniques from this recipe to add flavorful grilled chicken to the spaghetti squash mac and cheese.
