Ingredients You’ll Need

This Spaghetti Squash Mac and Cheese recipe calls for simple, everyday ingredients that deliver incredible flavor and texture. Each component plays an important role, whether it’s adding creaminess, a subtle earthiness, or that irresistible cheesy punch you love.

• Spaghetti Squash: The star of the dish, this squash naturally separates into spaghetti-like strands that replace traditional pasta, keeping things light and gluten-free.
• Olive Oil: Brushing the squash with olive oil adds a subtle richness and helps the flavors meld beautifully during roasting.
• Fine Sea Salt: Enhances the natural sweetness of the squash and balances the cheese sauce perfectly.
• Garlic Powder: Brings a gentle, savory warmth without overpowering the other flavors.
• Pepper: Just a pinch to add mild heat and depth to the squash.
• Salted Butter: Forms the base for a luscious cheese sauce that’s smooth and comforting.
• All-Purpose Flour: Works as a thickening agent, turning that buttery mixture into a silky roux for the cheese sauce.
• Whole Milk: Adds creaminess and helps create a velvety sauce that clings perfectly to the squash strands.
• Sharp Cheddar Cheese: Divided into portions for melting and folding in, it delivers that classic, tangy cheesy flavor that everyone loves.

How to Make Spaghetti Squash Mac and Cheese

Step 1: Roast the Spaghetti Squash

Start by preheating your oven to 400 degrees F so everything cooks evenly and gets a nice caramelized flavor. Cut your squash in half lengthwise and scoop out those seeds — this is your blank canvas for the dish. Brushing the inside with olive oil while sprinkling sea salt, garlic powder, and pepper ensures every bite bursts with flavor. Place the squash cut-side down in a baking dish filled with a little water, then cover it with foil to trap in moisture. Roast for 45 to 60 minutes until the squash is tender and easy to shred. Let it cool before moving on to the fun part!

Step 2: Shred the Spaghetti Squash

Using a fork, gently scrape the flesh of the squash into long, noodle-like strands, making sure to leave the shell intact while you prepare the cheese sauce. This not only saves on cleanup but keeps the strands fluffy and ready to soak up the cheesy goodness. The texture of these strands is what makes this dish shine, so take your time to get a nice, even shred.

Step 3: Make the Cheese Sauce

In a saucepan, melt the salted butter over medium heat, then whisk in the flour to create a smooth roux that thickens without lumps. Gradually add whole milk, stirring constantly for a creamy base. Sprinkle in salt and garlic powder to enhance the depth of flavor. Once the sauce is thick and bubbly, fold in most of the sharp cheddar cheese until melted and smooth, reserving a little for topping later. This sauce is the heart and soul of your Spaghetti Squash Mac and Cheese, so make sure it’s silky and perfectly cheesy.

Step 4: Combine and Bake

Carefully spoon the cheesy sauce over the shredded spaghetti squash right inside its shell or transfer everything to a baking dish. Top with your reserved cheddar for a golden, bubbly crust. Pop it back in the oven at 400 degrees F for about 10 minutes or until the cheese on top is beautifully melted and just starting to brown. This final step brings everything together, making each bite ooze with creamy, cheesy goodness.

Garnishes

For a little crunch, consider toasted breadcrumbs or crushed nuts sprinkled over the dish just before serving.

This dish pairs beautifully with simple green salads or roasted vegetables for a well-rounded meal. If you want to add a protein, grilled chicken or crispy bacon bits complement the creamy squash and cheese flavors wonderfully.

Creative Ways to Present

Alternatively, portion it into small ramekins for individual servings, making it perfect for dinner parties or cozy family meals.

Make Ahead and Storage

Storing Leftovers

Store any leftover Spaghetti Squash Mac and Cheese in an airtight container in the refrigerator for up to 3 days. The flavors will deepen nicely, making reheated servings just as enjoyable as fresh made.

Freezing

This dish freezes quite well. Transfer cooled leftovers to a freezer-safe container, leaving some room for expansion, and freeze for up to 2 months. Thaw overnight in the fridge before reheating to maintain the best texture and flavor.

Reheating

Reheat leftovers gently in the oven at 350 degrees F until warmed through, or microwave on medium power with a splash of milk to keep the cheese sauce creamy. Be careful not to overheat as it can cause the cheese sauce to separate.

FAQs

Can I use a different type of cheese?

Absolutely! While sharp cheddar offers a classic flavor, you can experiment with mozzarella, gouda, or a blend of cheeses to suit your taste preferences. Just keep in mind that some cheeses melt differently and may change the texture.

Is Spaghetti Squash Mac and Cheese gluten-free?

The recipe itself can be gluten-free if you substitute the all-purpose flour with gluten-free alternatives like tapioca starch or cornstarch. This way, you can enjoy this comforting dish even if you need to avoid gluten.

How do I pick the right spaghetti squash?

Look for squash that feels heavy for its size with a firm, bright yellow skin free from soft spots or blemishes. This usually means it’s fresh and sweet, perfect for your mac and cheese adventure.

Can I make this recipe vegan?

Yes! Use plant-based butter, dairy-free milk, and vegan cheese alternatives to create a creamy sauce without dairy. The spaghetti squash strands provide the perfect canvas for these flavors.

What should I do if my squash isn’t shredding well?

Make sure your squash is fully cooked and tender. If it’s tough, roast it a little longer. The longer cooking time helps the flesh separate into strands instead of mushy pieces.
