Spaghetti Squash: The Veggie Pasta Alternative

There’s more to spaghetti squash than meets the eye. The yellow gourd serves as a fantastic substitute for traditional pasta but is also packed with nutrition. With its long, yellow spaghetti-like strands, the fleshy squash is a light option as the star of your plate. While it’s not pasta, it makes a great substitute because it’s not as heavy to digest, and has a lower carbohydrate impact on your macros, and for those that need it, it’s gluten-free. If you’ve never had spaghetti squash, it’s a perfect substitute for spaghetti because the texture is slightly firm yet tender and has a mild flavor profile. While in this recipe, we’re showing spaghetti squash and lentils, the squash complements a wide range of sauces and ingredients such as lentil bolognese, paired with a cheese sauce, or even a stuffed spaghetti squash recipe. 


How to Cook Spaghetti Squash 

There are a few methods to prepare spaghetti squash, depending on how you prefer to cook. Roasting is a popular choice as it releases the natural sugars in the squash, intensifying its flavors and creating a slightly earthy aroma. Some people have also roasted their spaghetti squash in the air fryer, which may take less time considering the smaller space.  If you’re looking to retain more of the starchy flavor, steaming is a good alternative. It ensures that the strands remain firm and separate, ready to soak up your chosen flavors. Our favorite method is to cut the squash in half and then roast it. But how you prepare it will ultimately determine its flavor. 


How to cut spaghetti squash

To the unfamiliar, it can be a little intimidating to prepare spaghetti squash, especially if you don’t know how to cut it. Many grocery stores offer to prepare your spaghetti squash or zoodles for you, but they often come in plastic packaging. Since recycling rates are abysmal, reduce the waste by preparing it yourself. The best way to cut a spaghetti squash is with a very sharp knife. Start by finding the flattest side of your squash and place the flat side down on the cutting board. Take a large, sharp knife and cut long ways through the middle. Then turn the squash the other way, and finish the cut to the other side. We’ve included a video below that shows you how we cut it. 

From here, you can cover your squash with a little olive oil and seasonings and roast it in the oven on a rimmed baking sheet. Our exact instructions and seasonings are in the recipe below. Once fork tender in the oven, remove the spaghetti squash from the oven and allow it to cool. Once cool to the touch, hold the spaghetti squash long ways and shred it with a fork. Be sure to watch the video for the full recipe and ideas on how to prepare!


What to Pair With Spaghetti Squash:

The possibilities are endless when it comes to serving spaghetti squash. You can go the classic route and top it with a rich marinara sauce for a comforting meal. Alternatively, you can elevate your culinary game by using spaghetti squash as a vehicle for various toppings. Think beans, lentils, a creamy sauce like our vegan cauliflower alfredo sauce, or your favorite mushroom and cauliflower bolognese.


I’m always looking for new ways to eat lentils and this way will definitely be added to the rotation! I used a spaghetti squash and added some cooked lentils mixed with veggies like carrots, onion, and celery on top of the spaghetti squash and then I mixed in some tahini dressing for a creamy and delicious sauce!

Lentils Basics: The Protein-Packed Powerhouse

Lentils are small but mighty!  A nutritional powerhouse, lentils deserve a prominent place in your diet. These small legumes are bursting with benefits, making them a go-to option for vegetarians and vegans. One of their notable qualities is their high protein content, providing you with a plant-based source of this essential nutrient. Alongside protein, lentils are also rich in fiber, vitamins, and minerals, making them a fantastic addition to any well-rounded meal plan. 

Lentils and Sustainability

Not only are they healthy for you, but lentils are also beneficial to the planet as they are nitrogen-fixing organisms, so they actually replenish nitrogen in soils, helping restore soil nutrients and prepare them for other common crops. Lentils and other pulses are great crops to help reduce pesticide usage amongst farmers and promote regenerative agriculture practices. 


Types of Lentils and Their Uses:

Lentils come in various colors, each with its unique characteristics and culinary applications. Green lentils, for example, hold their shape well during cooking, making them ideal for salads and side dishes. On the other hand, red lentils cook quickly and have a slightly sweeter taste, perfect for hearty soups and stews. If you’re looking for a visually striking option, beluga lentils are small and black, lending themselves beautifully to salads and more substantial meals. In this recipe, we’ll be using green lentils to provide a pleasing texture when mixed in with the soft, tender spaghetti squash. In general, you can use dry lentils or pre-cooked lentils for many lentil recipes, it just depends on how much time you have.
