Spaghetti Squash Bolognese gives a comfort food classic a nutritious makeover that never feels like a compromise. With roasted squash strands instead of pasta, this dish is hearty enough to satisfy everyone at the table while keeping things light.

I leaned into this recipe one autumn when spaghetti squash was everywhere in the market and have never looked back since—my family went wild for the rich sauce and tangle of golden strands. When I served this on a chilly evening, my family could not even tell they were not eating real pasta. Now it is one of our favorite weeknight comfort foods, and nobody ever complains about the healthy swap.

Ingredients

  • Spaghetti squash: Look for a medium squash that feels heavy for its size with intact skin for best roasting
  • Ground beef: Choose lean beef for less excess fat yet plenty of savory flavor
  • Onion: Sweet or yellow onion works best diced small for even cooking and natural sweetness
  • Garlic: Fresh minced garlic deepens the sauce flavor and aroma
  • Diced tomatoes: Canned tomatoes provide brightness and balance the richness of beef
  • Tomato paste: Concentrated tomato flavor that thickens the sauce and adds depth
  • Italian seasoning: A blend of dried oregano basil and thyme gives classic bolognese notes
  • Salt and black pepper: Season to taste for balance
  • Parmesan cheese: A little grated parmesan brings salty nutty finish melt it over the hot sauce for best results

Instructions

Roast the Spaghetti Squash:
Start by preheating your oven to 400 degrees Fahrenheit. Arrange the squash on a baking sheet either whole or sliced in half with seeds removed. Brush the flesh lightly with oil if slicing. Bake for about 40 minutes until the skin gives easily to pressure and the strands pull easily with a fork. Let cool so it is safe to handle.
Brown the Beef Mixture:
Place a large skillet over medium heat. Add the ground beef and cook, breaking it apart with a wooden spoon. Once it starts to brown, add the chopped onion and continue to cook until fragrant and the onion looks translucent. Toss in the minced garlic and cook another minute to avoid burning.
Simmer the Sauce:
Stir in the canned diced tomatoes, the tomato paste and sprinkle in the Italian seasoning plus a pinch of salt and pepper. Stir well to combine. Scrape up the flavorful bits from the pan. Bring the mix to a low simmer. Reduce the heat and cook uncovered for 20 minutes. Let the sauce thicken and deepen in color.
Assemble and Serve:
Once the squash is cool enough, use a fork to gently scrape the inside into spaghetti like strands. Divide these among plates. Spoon generous helpings of the rich sauce over the squash. Finish with a big sprinkle of freshly grated parmesan to melt in and serve right away.

Spaghetti squash has become a fall favorite ingredient for me especially when the weather cools. It is so much fun to scoop out the golden spaghetti like strands and the kids love helping with it. The first time we gathered at the table to try this healthy version there was barely any sauce left at the end.

Storage Tips

Let any leftovers cool completely before storing. Transfer to an airtight container and keep in the fridge for up to four days. You can reheat in the microwave or warm gently on the stovetop for quick lunches. The sauce and squash will stay fresh and flavorful and the flavor deepens overnight.

Ingredient Substitutions

If you do not have ground beef try ground turkey chicken or even lentils for a vegetarian spin. The sauce is flexible enough for either white or red onion as well as a mix of canned crushed tomatoes. For more hidden veggies dice up carrot and celery and sauté them with the onion.

Serving Suggestions

Serve with a big green salad or roasted broccoli for extra color and crunch. A hunk of crusty bread is always welcome at the table or add a handful of fresh basil leaves right before serving for a bright finish.

Cultural and Seasonal Context

Spaghetti squash is at its peak in the fall and early winter which makes this recipe a great choice when market stalls are piled high. It is a playful take on traditional Italian bolognese that fits right into a modern weeknight meal. No one misses the pasta.

Seasonal Adaptations

In the peak of fall try adding chopped carrot and celery for added richness. Swap in roasted butternut or acorn squash strands if spaghetti squash is unavailable. For spring or summer use fresh tomatoes in place of canned if you have a garden bounty.

Success Stories

When I first made this with a group of friends only one of them knew it was not classic spaghetti noodles. Everyone was shocked at how easy and filling squash could be. It is a dependable dinner if you want to impress with something wholesome.

Freezer Meal Conversion

Both the sauce and roasted squash can be made ahead. Cool the components and freeze them separately in airtight containers for up to two months. Thaw overnight and reheat to serve for a low effort cozy meal.
