• Meal prep–friendly – Keeps well in the fridge for up to five days and reheats easily.

Ingredients

• SPAGHETTI SQUASH – Choose one that feels heavy for its size, with a firm, golden-yellow skin.
• AVOCADO OIL – For roasting at high temperatures.
• SALT & FRESH PEPPER – I use Real Salt, but any fine salt will work.

How to Cut Spaghetti Squash

Larger spaghetti squashes can be tricky to slice, but a large, sharp knife makes quick and easy work of it.

1. Remove the stem so the squash will stand up straight.
2. Stand it upright on a cutting board and slice it in half lengthwise, pressing the blade down firmly with both hands. If your knife gets stuck halfway through, gently tap the whole squash on the cutting board to help it split.
3. Scoop out the seeds with a spoon.

How to Cook Spaghetti Squash

Step 1. Preheat the oven to 425°F and line a rimmed sheet pan with unbleached parchment paper.

Step 3. After cutting and deseeding the squash, slather both the inner flesh and skin with the avocado oil. Sprinkle a large pinch of the salt over the flesh.

Step 3. Place the squash, cut side down, on the baking sheet to trap steam inside. This keeps the squash moist while speeding up the cooking process.

Step 4. Roast until the squash is fork-tender, but not mushy, about 25-30 minutes. While the squash roasts, prepare a sauce and protein of choice if desired.

Step 5. Cool for 5-10 minutes before handling. Use tongs to hold each half in place while you scrape the flesh with a fork to create spaghetti-like strands. Scrape the squash widthwise to follow the natural direction of the strands. Discard the skin.

Step 6. Season the spaghetti squash with the remaining salt and pepper to taste and serve as a side dish, or add your favorite sauce and a protein of choice for a full meal.

Step 7. Store leftovers in a sealed glass container in the fridge for up to 5 days.

Recipe Tips

Cook cut-side down for consistent results: This method steams the squash, reducing the overall cooking time and preventing it from drying out. I’ve tested the cut-side up method—it took twice as long to cook, and the squash was dry and mealy.

Don’t overbake: For the best texture, aim for just fork-tender. You want it to mimic the texture of pasta with an al dente bite. Overcooking leads to mushy strands once you mix in your chosen sauce.

Skip the olive oil: Avocado oil has a higher smoke point, making it a safer choice for high-heat roasting.

What Sauce Goes with Spaghetti Squash?

• Pesto spaghetti squash is my favorite! I make a batch of Cashew Pesto when I want a creamy, dairy-free sauce, but Fresh Basil Pesto is delicious too. Both pair beautifully with shrimp, chicken, or fish.
• A traditional marinara with Ground Bison or ground beef is always a good choice.
• Maple Tahini Dressing with salmon is another tasty option.
