Spaghetti squash is often relegated to the role of a “pasta substitute,” buried under heavy marinara or meat sauce in an attempt to mimic a bowl of noodles. But when you treat this vibrant gourd as the star of a sophisticated, room-temperature salad, it takes on an entirely different character. By pairing the mild, slightly nutty strands of the squash with the salty, buttery silkiness of crisped prosciutto, you create a dish that feels elegant enough for a dinner party but simple enough for a weeknight.
Using the Instant Pot transforms the often-cumbersome process of roasting squash—which can take upwards of 45 minutes—into a quick, hands-off task that yields consistent results. This recipe leans into the contrast of textures: the tender crunch of the squash, the shatter-crisp edges of the Italian ham, and the brightness of a lemon-shallot vinaigrette. It’s a refreshing departure from heavy autumnal sides, offering a light yet savory profile that works beautifully across seasons.
Why You’ll Want to Make This Recipe
The primary appeal of this dish lies in its balance. Spaghetti squash is naturally sweet and watery; it needs bold, salt-forward partners to reach its full potential. Prosciutto provides that punch, especially when it is lightly rendered until it mimics the texture of high-end bacon bits.
Beyond the flavor profile, this recipe solves the “soggy squash” dilemma. By pressure cooking the squash just long enough to reach an al dente texture and then tossing it with a sharp dressing while still warm, the strands absorb the vinaigrette rather than sitting in a pool of water. It’s a versatile dish—equally at home as a light lunch, a side for roasted chicken, or a base for a grain bowl. Because it doesn’t rely on melted cheese or heavy creams, it holds up remarkably well at room temperature, making it a stellar candidate for potlucks or meal prep.
Ingredients
For the Squash
- 1 medium spaghetti squash (about 3 lbs): Look for one that feels heavy for its size with a firm, unblemished rind.
- 1 cup water: Essential for creating the steam required for pressure cooking.
- 1 tablespoon extra virgin olive oil: To rub on the cut interior to prevent drying.
- ½ teaspoon kosher salt: To begin seasoning the strands from the inside out.
For the Salad & Vinaigrette
- 3 ounces thinly sliced prosciutto: Roughly torn into bite-sized pieces.
- ¼ cup extra virgin olive oil: Use a high-quality oil here, as it forms the base of the dressing.
- 2 tablespoons fresh lemon juice: About half a large lemon.
- 1 medium shallot: Finely minced to provide a delicate onion bite.
- 1 teaspoon Dijon mustard: This acts as an emulsifier and adds depth.
- ½ cup fresh parsley: Coarsely chopped for a hit of green.
- ¼ cup toasted pine nuts: For a buttery, resinous crunch.
- ½ cup shaved Parmesan or Pecorino Romano: For a final layer of umami.
- Freshly cracked black pepper: To taste.
How to Make Instant Pot Prosciutto and Spaghetti Squash Salad
1. Prep the Squash
Using a sharp chef’s knife, slice the spaghetti squash in half crosswise (around the “waist”) rather than lengthwise. This results in longer, more noodle-like strands because the fibers grow in a circular pattern around the fruit. Use a large spoon to scrape out the seeds and pulpy center. Rub the cut edges and the interior with a little olive oil and a pinch of salt.
2. Pressure Cook
Place the stainless steel trivet into the Instant Pot liner and add 1 cup of water. Position the squash halves on the trivet, cut-side up or stacked slightly if needed. Close the lid and set the steam vent to “Sealing.” Select Manual/Pressure Cook on High for 7 minutes.
3. Quick Release and Cool
Once the timer beeps, immediately perform a Quick Release by carefully moving the vent to “Venting.” This is crucial; letting the squash sit on natural release will turn the texture into mush. Once the pin drops, remove the lid. Use tongs to transfer the squash to a baking sheet to cool slightly.
4. Crisp the Prosciutto
While the squash is steaming, place a small skillet over medium heat. Add a teaspoon of olive oil and the torn prosciutto pieces. Fry for 3–5 minutes, stirring occasionally, until the ham turns a deep burgundy color and becomes crisp. Remove with a slotted spoon and drain on a paper towel.
5. Whisk the Vinaigrette
In a large mixing bowl, whisk together the minced shallot, lemon juice, Dijon mustard, and a pinch of salt. Slowly stream in the ¼ cup of olive oil while whisking constantly until the dressing is thickened and opaque.
6. Shred and Toss
Once the squash is cool enough to handle, use a fork to scrape the flesh into long, spaghetti-like strands. Add the warm squash directly into the bowl with the vinaigrette. Toss gently to ensure every strand is coated.
7. Assemble the Salad
Fold in the chopped parsley, toasted pine nuts, and the crisped prosciutto. Transfer the salad to a serving platter and finish with the shaved Parmesan and a generous amount of black pepper. Serve warm or at room temperature.
Helpful Recipe Tips
- Mind the Size: If your squash is particularly large (over 4 lbs), increase the pressure cook time to 9 minutes. If it’s a petite “personal” squash, drop it to 5 minutes.
- Drain the Excess: Spaghetti squash holds a lot of moisture. If you notice a pool of liquid at the bottom of the bowl after shredding, drain the strands in a colander for two minutes before adding them to the dressing.
- Toast the Nuts: Never skip toasting the pine nuts. A quick two-minute toss in a dry pan over medium heat unlocks oils that significantly improve the overall aroma of the salad.
Mistakes to Avoid
- The “Mush” Factor: The biggest mistake people make with Instant Pot squash is letting it sit in the pot after the cycle finishes. The residual heat is intense. Perform that quick release immediately to preserve the “snap” of the vegetable.
- Under-Seasoning: Spaghetti squash is quite bland on its own. It requires more salt and acid than you might think. Always taste a strand before serving and adjust the lemon or salt if it feels flat.
- Overcrowding the Skillet: When crisping the prosciutto, don’t dump it in a heap. Spread it out so it fries rather than steams.
Variations and Ingredient Swaps
- The Nut Swap: If pine nuts are too pricey or unavailable, toasted slivered almonds or chopped walnuts provide a similar textural contrast.
- The Herb Twist: While parsley is classic, swapping half of it for fresh mint or basil adds a Mediterranean flair that pairs beautifully with the salty ham.
- Make it Vegetarian: Omit the prosciutto and add sun-dried tomatoes and Kalamata olives to maintain that savory, salty profile.
- Add a Kick: A pinch of red pepper flakes added to the vinaigrette provides a nice back-of-the-throat heat that cuts through the richness of the Parmesan.
How to Serve It
This salad is incredibly flexible. For a sophisticated lunch, serve it as is with a thick slice of crusty sourdough bread.
If you are serving this as a dinner side, it pairs exceptionally well with:
- Lemon-Herb Roasted Chicken: The acidity in the salad brightens the poultry.
- Grilled Shrimp: The light, clean flavors of the squash don’t overwhelm delicate seafood.
- White Wine: A crisp Sauvignon Blanc or a dry Pinot Grigio complements the salty-tart notes of the dish perfectly.
How to Store and Reheat
To Store: Keep leftovers in an airtight container in the refrigerator for up to 3 days. Note that the prosciutto will lose its crunch once refrigerated, but the flavors will actually deepen as the squash continues to marinate in the dressing.
To Reheat: This salad is best enjoyed at room temperature. If you prefer it warm, briefly microwave it for 30–45 seconds just to take the chill off. Alternatively, you can toss it in a warm pan for a minute. Avoid overheating, as the squash can become watery if cooked a second time.
