The Complete Shopping Rundown
- 1 medium spaghetti squash – You want one that feels heavy for its size.
- 1 tablespoon olive oil – for sauteing garlic and onions nice and slow.
- 3 cloves garlic, minced – this little punch packs big flavor.
- ½ cup chopped onion – gives sweetness and depth to your sauce.
- 1 red bell pepper, diced – adds color and a subtle sweetness.
- 1 teaspoon Cajun seasoning – make sure it’s got that right spicy mix.
- ½ cup heavy cream – for the creamy, dreamy sauce that coats the squash.
- ½ cup grated Parmesan cheese – sharp and nutty, melts right in.

Your Complete Cooking Timeline
- Start by preheating your oven to 400 degrees Fahrenheit. Cut your spaghetti squash in half lengthwise and scoop out those seeds. Nothing worse than crunchy seeds in creamy spaghetti strands!
- Place the halves cut-side down on a baking sheet and roast for about 30 minutes or until the flesh feels tender when poked with a fork. This step softens your squash so the pressure cooker can finish it fast.
- While squash roasts, heat olive oil in a skillet over medium heat. Toss in garlic and onion. Saute until they smell fragrant and your eyes start to water a bit, which means you’re on the right track.
- Add in your diced red bell pepper along with Cajun seasoning, salt, and pepper. Let these cook for 5 minutes, just until your peppers soften up and soak in those spices. That’s where most flavor happens!
- Pour in heavy cream and sprinkle the Parmesan cheese in. Stir and let the mixture simmer gently for 2 to 3 minutes until it thickens and gets all creamy.
- Once your squash is out of the oven, use a fork to scrape the insides into long spaghetti-like strands right into a big bowl. Don’t forget it’s hot so slow and steady here.
- Finally, pour the creamy Cajun sauce over those squash strands and toss everything together. Garnish with fresh parsley if you got it handy. Serve hot.
Valve Hacks You Need to Know
- If you’re in a hurry, do a slow release for about 5 minutes before flipping the valve to quick release. It keeps the squash from splattering and losing moisture fast.
- Keep an eye on the float valve during pressure build. If it lifts unevenly, your lid might not be on just right, so double-check to keep steam locked in.
- Give your cooker a quick shake after putting the squash inside to make sure all bits are evenly touching the broth depth. It helps with even cooking.
When You Finally Get to Eat
That first bite you take is creamy and bold with Cajun spice that sneaks up nicely. The squash strands have a delicate snap and soak up the sauce real good.
Each forkful has that soft hit of roasted veggies and garlic warmth. You might notice the parmesan adds a little salty punch that just rounds it all out.

The color pops bright red and green from peppers and parsley, making your plate look as good as it tastes. This ain’t just dinner; it’s a cozy bowl of comfort you made yourself.
Eatin' this, you feel like you nailed that balance of health and satisfaction. You gotta be proud, y’all!
Your Leftover Strategy Guide
- Keep leftovers in airtight containers in the fridge. They stay creamy but you’ll wanna eat ’em within 3 days for best flavor. The sauce thickens up but a quick reheat with a splash of broth fixes it easy.
- Freeze extras by portioning into freezer-safe containers. When thawed and reheated, the texture’s not quite fresh but still delightfully cozy and perfect for lazy days.
- If you got packed lunches the next day, toss a cold serving on salads or warm it up in your microwave. The Cajun kick livens up quick meals fast.
Your Most Asked Questions Answered
- Q Can I skip the roasting step and just pressure cook the squash?
A You can try, but roasting gives that tender texture you want and a little sweet flavor that pressure cooking alone doesn’t quite get. - Q What if I don't have heavy cream?
A You can swap it out with full-fat coconut milk for a creamy twist that’s dairy free, but it changes flavor a bit. - Q How spicy is the Cajun seasoning here?
A It’s mild to medium heat, enough to tickle your tongue but not overpower. Add more if you like things hotter. - Q Should I use natural release or quick release?
A Natural release helps lock in flavor and texture for this dish but a slow release step works best before quick releasing to avoid splatter. - Q Can I prep this ahead of time?
A Totally. Roast the squash and make the sauce, then mix just before serving. Keeps things fresh without extra stress. - Q What’s the best way to reheat leftovers?
A Warm them gently on the stove with a splash of broth or in the microwave with a cover so the sauce won’t dry out.
