Bake the squash. Place cut side down on a baking sheet and roast in the oven at 400°F for 45 minutes.

Roast the veggies. On a separate baking sheet lined with foil, add the cherry tomatoes and garlic. Drizzle with olive oil and balsamic vinegar. Sprinkle with salt and pepper. After the squash has been roasting for 25 minutes, place the tomatoes in the oven to roast for the remaining 20 minutes.

Cool it down. Remove both the spaghetti squash and tomatoes from the oven. Set the tomatoes aside. Allow the squash to cool slightly.

Make the noodles. Use a fork to pull the spaghetti squash strands into “noodles” from the squash and place in a large bowl.

Frequently asked questions

  • How do you make spaghetti squash not watery? To avoid a watery squash, sprinkle with salt before cooking to draw out the extra moisture, and roast the halves cut side down.
  • Is spaghetti squash fattening? Not at all! Spaghetti squash is a filling low calorie food with only half a gram of fat per cup! Plus, it’s packed with healthy nutrients, making it a great addition to your menu.
  • How do you cut a spaghetti squash in half? If you’re having a hard time cutting the spaghetti squash in half before roasting, I recommend using an electric knife. If you don’t have an electric knife, put the whole spaghetti squash in the oven for 10-15 minutes. Remove it from then oven, then slice it in half once it’s cool enough to touch. Starting the cooking process slightly will help soften the outside of the squash and make it easier to cut in half.
