DIY Pasta Substitute for Keto

No need to hunt down specialized ingredients or pricey alternatives for your noodle dishes. There are a few easy homemade keto alternatives that you can prepare right at home!

1. Spiralized Vegetables

While pasta has many different types of substitutes, spiralized vegetables are one of the best alternatives. Spiralizing vegetables is a simple, quick, and easy way to make low-carbohydrate keto noodles that can be substituted for traditional pasta. And there are several ways to do it!

Tips for making vegetable noodles

Firm vegetables work best with this method. Choose from zucchini, carrots, turnips, beets, and cucumbers.

  1. Use a spiralizer. This is a kitchen device designed precisely for this purpose! It cuts vegetables into long, flat strands resembling noodles. Simply trim vegetable to fit on prongs, turn the crank, and pull noodles straight as they come out. You can even buy one to attach to your stand mixer.
  2. Cut them manually. Don’t have a spiralizer? All you really need is a sharp knife. Slice vegetables crosswise and into long, flat strands resembling noodles. 
  3. Be creative with other tools. You can also use a julienne peeler, Y-shaped vegetable peeler, or mandoline to make thin, flat veggie “noodles” that are perfect for lasagna dishes.

Preparing Zucchini Noodles Correctly

Zucchini noodles, also known as zoodles, are a popular keto pasta alternative. They are light, flexible, and have a mild taste. This mild flavor makes zoodles the perfect choice for many seasonings and sauces. 

Once you spiralize or slice your zoodles, be sure to drain them on a paper towel and sprinkle with salt. The salt will draw some of the water out of the zucchini, resulting in better flavor and texture.

Then, use them immediately or transfer them to an airtight container and place them in the refrigerator. The zoodles will stay fresh for 2-3 days.

You can have an egg-based, gluten-free zucchini noodle casserole as a side dish for brunch, or whip up a refreshing salad for summer. You can also use zoodles to make a big pot of chicken “noodle” soup for colder days.

2. Cabbage Noodles

Cabbage is an unconventional yet nutritious low-carb alternative to wheat pasta. It  is an excellent source of folate and contains numerous vitamins and minerals including Vitamin C and Vitamin K.

Cabbage noodles are also low in calories and fat, making them a healthy option for those who give up conventional pasta. 

You can use whole or sliced cabbage leaves to make a filling and fresh-baked keto lasagna. Some also prefer finely chopped cabbage for this dish, saying it makes the lasagna easier to serve and eat.

Heads of cabbage, sliced into strips and boiled, also make a good substitute for noodles in Asian-style dishes such as pad thai or lo mein. 

3. Spaghetti Squash

Spaghetti squash is another popular keto pasta alternative that can be a great way to get your daily dose of vitamin A and potassium. It is a large, yellow-orange-fleshed winter squash that originated in North and Central America. When cooked, its flesh separates into long strands, similar in appearance to spaghetti — hence its name.

There are several different ways to prepare it, including in an Instant Pot or a slow cooker! If you don’t have any fancy kitchen gadgets, you can use one of these simple methods instead:

  • Stovetop: Poke holes all over the squash with a fork, then place it in a large pot. Cover with water and bring to boil, then simmer for about 20 minutes.
  • Oven: Slice the squash in half and scoop out the seeds. Place cut-side down in a baking dish and roast for 30-45 minutes at 400 degrees. 
  • Microwave: Place a seeded squash half, cut-side down, in a casserole dish with some water and cover in plastic wrap. Cook on High for 8-10 minutes, or until tender.

Once tender, scrape a fork along the inside of the squash to remove the flesh. It will come out in strands — an easy pasta substitute for keto!

Spaghetti squash can be served with any number of different toppings, including marinara sauce or creamy Alfredo sauce. You can use it in a sweet-savory pad thai or a keto-friendly Filipino pancit bihon.

5. Sprouts

If you’re looking for a pasta substitute that’s keto with minimal prep, look no further than sprouts! Rich in nutrients and easy to digest, sprouts are germinated seeds that have become young plants.

8. Kelp Noodles

Kelp noodles are made entirely from seaweed. They don’t have a strong flavor of their own, which allows them to soak up complex flavors from other ingredients. They are often used in Asian dishes, but their neutral flavor profile works well in other cuisines, too.

FAQs about keto pasta alternatives

If you don’t see your question answered below, don’t be afraid to let us know in the comments!

What’s a good keto substitute for pasta?

Substitutes quite often depend on what type of dish you are making, along with your own flavor preferences and dietary needs. It’s always good to have a variety of keto pasta alternatives on hand so you can choose the right substitute for each recipe.

For instance, zucchini noodles are best served in fresh salads and summertime dishes. Shirataki noodles are ideal for hot soup or broth-based recipes. Spaghetti squash noodles are an excellent alternative to traditional pasta in a tomato sauce.

What keto alternative can I cook instead of pasta?

If you follow the keto diet, you might avoid wheat pasta or other carbohydrates. However, if you would want to cook some pasta with a tasty sauce, you might be interested in trying keto-friendly alternatives. Pasta substitutes for keto can be integrated into a variety of recipes that traditionally call for pasta, such as fettuccine alfredo, marinara, and lasagna. 

Just keep in mind that apart from keto alternatives, basically any noodle or pasta that is made with flour or rice is out. Pastas made with flour, such as spaghetti, ziti, penne, and fettuccini, are not keto friendly. Noodles made from rice flour and wheat flour plus eggs, such as rice noodles and egg noodles, are also off-limits on the keto diet.

Can you have pasta on keto?

Yes, you can still enjoy pasta when following a ketogenic diet. The trick is to choose low-carbohydrate and gluten-free pasta varieties, such as the options listed above. Traditional wheat pasta is very carb heavy and not allowed with keto.

That said, not all pasta is considered the same! The overall carb content of each type of pasta will determine whether or not it can be consumed in keto-friendly quantities. Carbohydrates aren’t necessarily bad for you, but too many will kick you out of ketosis and keep you from burning fat. That’s why you need to use keto alternatives for pasta.

What pasta keto substitute is lowest in carbs?

Shirataki noodles are a remarkable alternative to pasta, with nearly zero calories and a high concentration of soluble fiber. ​Shirataki noodles consist of 97% water and contain 3% glucomannan fiber, making them very low in calories and digestible carbohydrates.

According to Healthline, shirataki noodles are essentially calorie-free, carb-free foods, containing about 1-3 grams of glucomannan in a typical 4-ounce (113-gram) serving.
