How to Make Spaghetti Squash Bolognese

Wash and Slice: Start by giving the spaghetti squash a good rinse. Carefully slice it in half using a sharp knife, revealing its beautiful inner flesh.
Scoop Out Seeds: Grab a spoon and scoop out the seeds and stringy flesh inside the squash. This will prepare it for roasting, leaving you with the perfect vessel for your sauce.
Season the Flesh: Drizzle some olive oil, sprinkle salt, and add black pepper onto the flesh of the squash. Place the halves cut-side down on a prepared baking sheet lined with parchment paper.
Bake to Perfection: Pop the squash in a preheated oven at 350°F and bake for 40-45 minutes. The flesh should be golden brown and tender when you test it with a fork.
Cool Down: Let the squash cool for about 10-15 minutes after baking. This makes it easier to handle and allows the flavors to settle.
Create Spaghetti Strands: Flip the roasted squash over and use a fork to scrape the flesh, creating delightful spaghetti-like strands. It’s a fun step that transforms your veggie!
Set Squash Aside: Transfer all those lovely spaghetti strands to a bowl and set aside while you whip up the bolognese sauce.
Sauté Onion and Garlic: In a skillet over medium heat, add a drizzle of cooking oil, then toss in the diced onion and minced garlic. Sauté until the onion turns translucent, about 1-2 minutes.
Cook the Ground Beef: Stir in the ground beef and break it apart with a wooden spoon. Cook until the beef is no longer pink, about 3-4 minutes.
Add Balsamic Vinegar: Pour in the balsamic vinegar and stir everything to combine. This will add a depth of flavor to your bolognese.
Mix in Tomatoes and Seasonings: Now, add the drained diced tomatoes, crushed tomatoes, Italian seasoning, salt, and pepper. Stir well and let it simmer for 10 minutes, stirring occasionally.
Combine and Serve: Finally, add the spaghetti squash to the skillet, mixing it with the bolognese sauce. Taste and adjust the seasoning as needed. Serve the dish warm and enjoy!

Optional: Garnish with freshly grated Parmesan cheese for a delightful finish.

Expert Tips for Spaghetti Squash Bolognese

Choose the Right Squash: Opt for a firm, heavy spaghetti squash that feels dense; this means it’s ripe and will yield the best results.

Slice Carefully: When cutting the squash, use a sharp knife and apply even pressure. Proper slicing ensures a clean cut, making it easier to scoop out seeds.

Don’t Skip the Cooling: Allow the roasted squash to cool before scraping the strands. This makes handling easier and helps maintain the ideal texture for your Spaghetti Squash Bolognese.

Simmer with Patience: Give your bolognese sauce enough time to simmer; this deepens the flavors beautifully. Avoid rushing this step for a more robust taste.

Season to Taste: Always taste as you go! Adjust the seasoning towards the end after combining the squash and sauce to ensure a perfectly balanced dish.

Spaghetti Squash Bolognese Recipe FAQs

How do I choose the best spaghetti squash?
Absolutely! When selecting a spaghetti squash, look for one that is firm and heavy for its size. It should have a smooth skin with no dark spots or blemishes, indicating freshness. If you gently shake it and feel the seeds rattling inside, it’s past its prime, so aim for a squash that feels dense and solid.

How long can I store leftover Spaghetti Squash Bolognese in the fridge?
Very! Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To ensure the dish remains fresh, wait until the bolognese has cooled down before sealing it to avoid condensation, which could make it watery.

Can I freeze Spaghetti Squash Bolognese, and how do I do it?
Definitely! To freeze your Spaghetti Squash Bolognese, let it cool completely first. Transfer the bolognese sauce into freezer-safe containers or heavy-duty freezer bags, ensuring to keep portions manageable. For the spaghetti squash, you can freeze the strands separately in a bag as well. Both can be kept for up to 3 months. Just remember to label them with the date!

What’s the best way to reheat frozen Spaghetti Squash Bolognese?
Great question! For the best results, thaw your frozen bolognese in the refrigerator overnight. Then, reheat it gently on the stovetop over medium heat, stirring occasionally until warmed through. If you froze the spaghetti squash, you should reheat it separately in the microwave or on the stovetop, then combine it with the bolognese sauce for serving.

Is Spaghetti Squash Bolognese dog-friendly, or should I avoid certain ingredients?
Very! While spaghetti squash itself is safe for dogs to eat, it’s important to be cautious with the bolognese sauce. Avoid feeding your pup anything with garlic or onion, as these can be harmful to dogs. If you want to share a healthy dish with your furry friend, simply offer plain spaghetti squash without the sauce.

What if my spaghetti squash doesn’t shred properly?
Oh no! If your spaghetti squash doesn’t shred into strands easily, it might not be fully cooked or it could be overcooked. Make sure to cook it until it’s tender—I usually bake mine until the flesh is golden brown and a fork easily pierces it. If that doesn’t work, try using a stronger fork in a scraping motion instead of digging in, and it should start to come apart like spaghetti!
