History:
The word primavera means “spring” in Italian, and pasta primavera is generally associated with pasta tossed with fresh vegetables and a light, flavorful sauce. Despite its Italian-sounding name, the dish is strongly associated with Italian-American cuisine and became particularly popular in the United States during the 1970s.
Spaghetti Squash Primavera is a modern interpretation of this vegetable-rich style of cooking. Instead of traditional pasta, cooked spaghetti squash provides naturally stringy strands that pair beautifully with sautéed seasonal vegetables. Using an Instant Pot adds another modern convenience by significantly simplifying the squash-cooking process.

Instructions
Prepare the Spaghetti Squash
- Wash the spaghetti squash and carefully cut it in half crosswise or lengthwise.If cutting lengthwise feels difficult, cutting it crosswise can make the strands longer because of the squash's internal structure.Scoop out the seeds and stringy center using a spoon.
Pressure Cook the Squash
- Pour 1 cup of water into the Instant Pot.Place the trivet inside the pot and arrange the squash halves on top of the trivet. If necessary, cut the squash into smaller pieces so they fit comfortably.Close and lock the lid.Set the Instant Pot to High Pressure for 7 minutes.Once the cooking time is complete, carefully perform a quick release according to your Instant Pot's instructions.Open the lid once the pressure has fully released.
Scrape the Squash
- Carefully remove the hot squash using tongs.Allow it to cool for several minutes until it is safe to handle.Use a fork to scrape the flesh into long spaghetti-like strands.Set the strands aside.If the squash is very watery, allow the strands to drain briefly in a colander.
Sauté the Garlic and Vegetables
- Set the Instant Pot to Sauté, or use a separate large skillet.Add olive oil and allow it to heat.Add minced garlic and cook for approximately 30 seconds, stirring frequently.Add the zucchini, bell pepper, and carrot.Cook for 3–4 minutes, stirring occasionally, until the vegetables begin to soften while retaining some texture.
Add Tomatoes and Seasonings
- Add the cherry tomatoes, Italian seasoning, red pepper flakes if using, salt, and black pepper.Cook for another 2–3 minutes.The tomatoes should soften slightly without completely breaking apart.
Add the Spinach
- Add the fresh spinach to the vegetables.Cook for approximately 1–2 minutes, stirring gently, until the spinach wilts.Do not overcook the vegetables. Primavera is especially delicious when the vegetables retain some color and texture.
Combine with Spaghetti Squash
- Add the cooked spaghetti squash strands to the vegetable mixture.Gently toss everything together until the squash is evenly coated with the vegetables, garlic, and herbs.If using butter, add it now and toss until melted.
Finish with Lemon and Parmesan
- Turn off the heat.Add fresh lemon juice, lemon zest, and Parmesan cheese.Gently toss until the cheese is distributed throughout the squash.Taste and adjust the salt and black pepper if needed.
Garnish and Serve
- Transfer the Spaghetti Squash Primavera to a serving dish.Sprinkle with fresh parsley and additional Parmesan cheese.For extra freshness, add a little chopped basil and another squeeze of lemon juice.Serve immediately while warm.
Notes
- Squash size: A medium spaghetti squash generally fits comfortably in a standard 6-quart Instant Pot.
- Cooking time: Smaller squash may need slightly less time, while larger squash may require additional pressure-cooking time.
- Natural release: A quick release helps prevent the squash from becoming excessively soft.
- Vegetable texture: Cut vegetables into similarly sized pieces so they cook evenly.
- Fresh tomatoes: Cherry tomatoes work particularly well because they soften without becoming completely mushy.
- Cheese: Freshly grated Parmesan provides the best flavor and texture.
- Lemon: Add lemon juice at the end to preserve its bright, fresh flavor.
- Protein: Cooked chicken, shrimp, or another preferred protein can turn this into a more substantial meal.
Tips for Pot Spaghetti Squash Primavera:
- Do not overcook the squash: The goal is tender strands that still have some structure.
- Use the trivet: Keeping the squash above the water prevents it from becoming waterlogged.
- Drain if necessary: Excess moisture can make the finished primavera watery, so drain the squash strands when needed.
- Keep vegetables crisp-tender: Primavera tastes best when vegetables retain some bite and vibrant color.
- Add spinach last: Baby spinach needs very little cooking and can become overly soft if added too early.
- Use fresh garlic: Freshly minced garlic creates a more pronounced flavor than garlic powder.
- Finish off the heat: Adding Parmesan and lemon after cooking helps preserve their flavor and prevents the cheese from becoming overly sticky.
- Taste before serving: The amount of salt needed depends on the Parmesan and other ingredients, so adjust seasoning at the end.
FAQs for Pot Spaghetti Squash Primavera:
1. Can I cook a whole spaghetti squash in the Instant Pot?
A whole squash can sometimes fit depending on its size and the pressure cooker, but cutting it in half is generally more practical and allows you to remove the seeds before cooking.
2. How long should I cook spaghetti squash in an Instant Pot?
For a medium squash cut in half, 7 minutes at high pressure is a useful starting point. Exact timing can vary depending on the squash’s size and desired texture.
3. Why is my Instant Pot spaghetti squash watery?
Spaghetti squash naturally contains considerable moisture. Using the trivet, avoiding excess cooking time, and draining the strands before combining them with the vegetables can help.
4. Can I use frozen vegetables?
Yes. Frozen vegetables can be used, although fresh vegetables generally provide better texture for primavera. If using frozen vegetables, avoid overcrowding the pan.
5. Can I make this recipe dairy-free?
Yes. Omit the Parmesan and butter. Add extra olive oil, nutritional yeast, or a dairy-free Parmesan alternative if desired.
6. Can I add meat to Spaghetti Squash Primavera?
Absolutely. Cooked chicken, shrimp, turkey, or another preferred protein can be added after the vegetables are cooked.
7. Can I make this recipe ahead of time?
Yes. The spaghetti squash can be pressure-cooked ahead of time and refrigerated. Prepare the vegetables and combine everything shortly before serving for the best texture.
8. How should I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat gently in a skillet or microwave until warmed through.
