Spaghetti Squash Bolognese

This recipe is a wonderful replacement for traditional pasta. Spaghetti squash can be roasted and used as a base for bolognese sauce instead of pasta noodles.

What I love about this recipe is that it’s low carb, it’s healthy, and it won’t leave you feeling bloated or too full.

The spaghetti squash is so easy to roast. While that’s cooking you can make the bolognese sauce on the stove. It requires a little more effort, but it’s worth it.

The result is an easy and delicious healthy dinner that’s low carb!

What You’ll Need To Make Spaghetti Squash Bolognese

This recipe uses a few simple ingredients that come together to make a delicious dinner. To keep things simple I used canned tomatoes. Here’s what you’ll need:

  • Spaghetti Sqash – You’ll need one spaghetti squash. This will be roasted with a bit of oil, salt and pepper.
  • Ground Beef – I prefer to use extra lean ground beef.
  • Onion and Garlic – This recipe uses 1 yellow onion and 3 minced garlic cloves.
  • Canned Goods – You’ll need diced tomatoes and crushed tomatoes.
  • Spices and Flavorings – For flavor I added balsamic vinegar, Italian seasoning, sea salt and ground pepper.

How To Make Spaghetti Squash Bolognese

  1. Roast The Squash – First, slice the squash in half and scoop out the inner seeds with a spoon. Season the flesh with salt and pepper, and a bit of cooking oil. I used avocado oil spray. Roast the squash facing down for 30-40 minutes. Let it sit for 10 minutes to cool, then use a fork to shred the spaghetti squash into strips.
  2. Make Bolognese – Add the onion and garlic to a skillet and cook until translucent. Next brown the beef with the onions. After that, add the diced tomatoes, crushed tomatoes, and spices. Let the sauce simmer for 10 minutes, stirring occasionally.
  3. To Serve – Add the spaghetti squash to a dish and top with the bolognese sauce. Season with salt and pepper. Serve and enjoy!

Chefs Tips

  • Try under-cooking the squash – Some people might prefer their spaghetti squash to be slightly undercooked. This will produce less “mushy” results – similar to when you cook pasta al dente. If so, try cooking for 25-30 minutes and letting it rest on the baking sheet face down for 10 minutes before flipping and shredding with a fork.
  • Let sauce simmer longer – It might be tempting to skip the 10 minutes of letting the sauce simmer, but this really helps to let the flavors marinate. Stir occassionally during this process.
  • Season with salt and pepper – The spaghetti squash definitely needs some salt and pepper once it’s cooked. Feel free to season to your tastes.
