Embracing the Instant Pot Phenomenon in Your Kitchen
It’s no secret that the Instant Pot has taken the culinary world by storm. This multi-functional kitchen appliance has quickly become a staple in countless homes, promising to simplify cooking, save time, and expand gastronomic possibilities. I’d love to take a quick survey: how many of you have recently invested in an Instant Pot, or perhaps you’ve been a pressure cooking enthusiast for years? The surge in popularity for this electric pressure cooker is truly remarkable, turning what was once a niche cooking method into a mainstream culinary “thing” – and for all the right reasons! Just browse through countless positive reviews to see why it’s so beloved.
My own journey with the Instant Pot began much like many others. I purchased my unit during a fantastic Amazon Prime Day deal, much like a Black Friday bargain. However, I must confess, it sat patiently in its box on my dining room table for several months. Eventually, I took it out, admired its sleek design, but it remained on the table, an unutilized piece of potential. I’m generally not one for reading lengthy manuals; I prefer to dive straight into using new gadgets. Yet, there was something about the idea of a pressure cooker – the steam, the sealed lid – that felt a little intimidating, if I’m being completely honest.

The turning point came thanks to my dear friend, Jennifer, who practically lives by her Instant Pot. She constantly raved about its capabilities, declaring it “Magic!” Her enthusiasm was infectious, and I found myself growing a little jealous of her effortless cooking experiences. After a delightful lunch with her one day, I decided it was time. With her virtual hand-holding and step-by-step guidance via text messages, I finally made my first dish: spaghetti squash. And she was absolutely right – it truly was magic, transforming a tough squash into tender strands with surprising ease.
Since that initial successful attempt, my Instant Pot has become a workhorse in my kitchen. I’ve ventured far beyond spaghetti squash, regularly preparing perfectly hard-boiled eggs, savory Mexican-style shredded beef, tender shredded chicken, and an astonishing variety of soups. Making soup in the Instant Pot has become a weekly ritual for me; the speed and depth of flavor it achieves are ridiculously satisfying. It’s safe to say, my initial apprehension has been replaced with genuine affection for this incredible appliance, especially for healthy meal prep.
Instant Pot vs. Slow Cooker: Understanding the Differences and Maximizing Both Appliances
A common question many home cooks ponder is the difference between a pressure cooker, like the Instant Pot, and a traditional slow cooker (Crock Pot). While both are fantastic kitchen tools, they serve distinct purposes, and I believe there’s a valuable place for each in a well-equipped kitchen. I certainly won’t be parting with my beloved slow cooker anytime soon! For me, the primary distinction lies in speed and convenience.
The Instant Pot excels at drastically reducing cooking times. Recipes that would typically simmer for hours in a slow cooker – think rich stews, tender roasts, or hearty bean dishes – can be ready in a fraction of that time under pressure. This is a huge advantage for those moments when your meal plan shifts unexpectedly, or you simply need a delicious, home-cooked meal without the extensive lead time. If you only loosely follow a meal plan during the week, the Instant Pot offers incredible flexibility, allowing you to whip up substantial meals much quicker if your schedule changes.
On the other hand, the slow cooker is perfect for “set it and forget it” cooking. It’s ideal for those days when you want to prep ingredients in the morning and return home to a fragrant, fully cooked meal. The low and slow method often develops unique flavors and textures that pressure cooking can’t replicate. My friend Bailey once brilliantly referred to the Instant Pot as “a slow cooker for procrastinators,” and I’ve adopted that phrase ever since. It perfectly encapsulates the Instant Pot’s ability to deliver slow-cooked results when you’re short on time, offering a compelling solution for modern, busy lifestyles.
Getting Started: Your First Instant Pot Creations for Success
If you’re like I was, with an Instant Pot still gleaming on your counter, don’t let intimidation hold you back any longer! The key is to start with simple, approachable recipes to build your confidence. This simple Instant Pot spaghetti squash recipe is an excellent starting point, offering rewarding results with minimal effort. Alternatively, mastering hard-boiled eggs in the Instant Pot is incredibly satisfying – the method I use guarantees perfectly peelable eggs every time. For something heartier, a healthy soup like this Chicken and Lentil Soup is another fantastic option to begin your pressure cooking journey.
I’ve been on a soup-making spree recently, perfecting a delicious Chicken Vegetable and Wild Rice Soup that I hope to share here on the blog very soon. And speaking of exciting new recipes, I recently stumbled upon this Instant Pot Refried Beans recipe and absolutely cannot wait to try it. I’m thoroughly enjoying the experimentation process with my Instant Pot and look forward to converting many of my existing favorite recipes to take advantage of its efficiency, making mealtime easier and faster.

The Undeniable Benefits of Instant Pot Spaghetti Squash for Meal Prep
But before we venture too far, let’s circle back to our star ingredient: spaghetti squash. Cooking spaghetti squash ahead of time is one of my absolute favorite meal prep strategies. It’s incredibly convenient to have it ready and waiting in the refrigerator, providing a healthy, low-carb base for countless meals throughout the week. For example, if I’m making traditional pasta for the rest of my family for dinner, having pre-cooked spaghetti squash means one less thing for me to prepare, allowing me to enjoy a delicious, wholesome meal tailored to my dietary preferences with minimal fuss.
Spaghetti squash offers a fantastic, nutrient-rich alternative to conventional pasta. It’s naturally low in calories and carbohydrates, and rich in essential vitamins, minerals, and fiber. When cooked properly, its unique strands mimic the texture of pasta, making it an excellent choice for those following low-carb, gluten-free, or whole food diets. The Instant Pot ensures a consistently tender result, eliminating guesswork and delivering perfect spaghetti squash every time, whether you’re making it for a single serving or batch cooking for the entire week.

Mastering Instant Pot Spaghetti Squash: A Simple Guide to Perfection
Preparing spaghetti squash in the Instant Pot is remarkably simple and straightforward, making it an ideal recipe for beginners and experienced pressure cooks alike. Follow these steps for perfectly cooked, fork-tender squash every time:
- Prepare the Squash: Carefully cut your spaghetti squash in half longways. A sharp, sturdy knife is essential here. If the squash is very hard, you can microwave it for a minute or two to soften the skin slightly, making it easier and safer to cut. Once halved, use a spoon to scoop out the seeds and stringy bits from the center, just as you would with a pumpkin or other winter squash.
- Set Up the Instant Pot: Place your two spaghetti squash halves onto the trivet (the metal rack with handles) inside your Instant Pot. The trivet keeps the squash elevated out of the water, ensuring it steams perfectly and doesn’t get waterlogged. Add exactly 1 cup of water to the bottom of the Instant Pot liner. This measured amount of water is crucial for creating the steam needed to bring the pot to pressure and effectively cook the squash. Secure the lid, ensuring the sealing ring is properly in place, and turn the pressure release valve to the “Sealing” position.
- Pressure Cook to Perfection: Select the “Manual” or “Pressure Cook” setting on your Instant Pot and set the cooking time for 7 minutes. The exact time may vary slightly based on the size of your squash (a very small squash might need 6 minutes, while a very large one could benefit from 8-9 minutes), but 7 minutes is a reliable average for a medium-sized squash. It will take a few minutes for the Instant Pot to come to pressure before the cooking countdown begins – this is a normal part of the process and depends on the initial temperature of the water and squash. Once the timer goes off and the cook time is complete, it’s time for the quick release. Carefully turn the quick release knob to the “Venting” position to release the steam. Be extremely cautious and always use a kitchen towel or oven mitts to protect your hand from the powerful, hot steam.
- Finish and Serve: Once all the steam has been safely released and the float valve has dropped, you can carefully remove the lid. Allow the spaghetti squash to cool for a few minutes before handling, as it will be very hot. Carefully remove the spaghetti squash halves from the Instant Pot and place them on a clean towel or cutting board. Using a fork, gently scrape out the squash strands from the skin – they should easily separate and resemble delicate spaghetti noodles. At this point, your spaghetti squash is ready to serve immediately as a delicious side dish, a healthy pasta substitute with your favorite sauce, or to be incorporated into another recipe. For convenient meal prepping, let it cool completely before storing it in an airtight container in the refrigerator for up to 3-5 days.

Serving Suggestions and Creative Recipe Ideas for Your Instant Pot Spaghetti Squash
Once you have your perfectly cooked Instant Pot spaghetti squash, the culinary possibilities are endless! You can simply toss it with a little butter, salt, and pepper for a delicious and healthy side dish that complements almost any main course. For a classic and satisfying meal, serve it with your favorite marinara sauce and meatballs, providing a fantastic gluten-free and low-carb alternative to traditional pasta. Its mild flavor also makes it an excellent base for various nutritious bowls – think Mediterranean-inspired with crumbled feta, Kalamata olives, and juicy cherry tomatoes, or an Asian-fusion bowl with stir-fried vegetables, grilled chicken, and a drizzle of peanut sauce.
Beyond being a simple side or pasta swap, consider incorporating spaghetti squash into more elaborate dishes. It works wonderfully in casseroles, such as a cheesy chicken and broccoli bake, adding texture and extra vegetables. Mix it into a frittata or quiche for a unique twist, or use it as a low-carb filling for stuffed bell peppers or zucchinis. Its versatility truly shines here, as you can transform one batch of cooked squash into several different and exciting meals throughout the week, minimizing cooking time and maximizing flavor. Don’t be afraid to experiment with your favorite seasonings and sauces – spaghetti squash is a blank canvas ready to soak up delicious flavors!
