Spaghetti squash bolognese is one of my favorite comfort food recipes and it's great as a make-ahead meal. It can last for several days in the refrigerator, along with cooked spaghetti squash. The sauce and cooked spaghetti squash noodles can also be stored in the freezer for a few months and thawed in the refrigerator overnight.
Here's my plant-based, low carb version of spaghetti and bolognese sauce. This recipe combines my Cauliflower Bolognese sauce with my Simple Spaghetti Squash recipe. You can find the omnivore's version of bolognese sauce in my cookbook, Cooking for the Specific Carbohydrate Diet page 160.
I also added my cashew cream recipe below if you decide to add some to the bolognese sauce to make it a bit richer and creamer. Cashew cream can be used with this plant-based version or the omnivore version in my cookbook. If you're doing dairy, top the plate with graded Parmesan. I recommend using a fresh chunk of Parmesan to avoid caking agents and additives that might be used in the pre-made graded version. Enjoy!

Cauliflower Bolognese
Equipment
- Food processor optional, to speed things along
Ingredients
- 2 tablespoons olive oil
- 1 small yellow onion peeled and roughly chopped
- 3 garlic cloves peeled and chopped
- 1 large carrot trimmed
- 2 tablespoons tomato paste or sub with thick tomato sauce
- ½ cup raw walnuts
- ¾ teaspoon salt
- ½ teaspoon oregano
- ½ teaspoon thyme
- ¼ teaspoon red pepper flakes
- 12 ounces cauliflower rice frozen or fresh, or one small head trimmed and pulsed in a food processor
- 2 pounds tomatoes, cut in quarters I use vine or plum tomatoes
- ¼ cup red lentils
- 1 tablespoon balsamic vinegar or sub with red wine vinegar
Instructions
- Pulse the carrots in a food processor, or use a knife to chop by hand until finely chopped.
- Add the onions and garlic to the food processor and pulse until finely chopped, or chop by hand.
- Warm up a large stock pot on a low heat and add the olive oil.
- Add the onion, garlic, carrot mixture to the pot and cook for a few minutes, stirring occasionally.
- Add the tomato paste and blend in to the mixture in the pot using a spatula or spoon.
- Pulse the walnuts in the food processor until very finely chopped, or chop by hand.
- Add the walnuts to the pot and blend in to the mixture with a spoon or spatula.
- Add the cauliflower to the pot and blend in to the mixture with a spoon or spatula.
- Add the salt, oregano, thyme, and red pepper flakes and blend well.
- Pulse the tomatoes in the food processor until crushed, or chop by hand.
- Add the tomatoes and lentils to the pot and blend well.
- Place a top over the pot and simmer for 20 to 30 minutes. If you didn't add lentils, take the top off the last 5 minutes to reduce the extra liquid, if any.
- At the end, add 1 tablespoon of balsamic vinegar and blend in. Adjust seasonings with salt and possibly a bit more vinegar depending on how acidic you prefer the sauce.
- Serve hot. Store in the refrigerator for a few days or freeze for a few months.

Simple Spaghetti Squash
Instructions
- Preheat your oven to 400℉.
- Prepare a baking sheet with parchment paper or a non-stick baking mat.
- Slice the spaghetti squash in half or in rings. See the recipes notes on help with slicing it.
- Scoop the seeds out, or leave them in and take them out once the squash is baked.
- Place each half open side facing down on the baking sheet. Pierce the outside of each half with a fork a few times to let moisture escape while baking. If you cut the squash into rings, place each ring on its side.
- Bake for 20 minutes.
- Take the squash out of the oven and turn it over to cool.
- Remove the seeds and use a fork to take out all the spaghetti squash.
- Add salt and other seasonings along with some olive oil (optional) or broth.
