Is Summer Squash Keto-Friendly?

Yes, summer squash is definitely a keto-friendly vegetable! Despite its natural sugars, summer squash is low in net carbohydrates. A 1-cup serving of fresh yellow squash contains approximately 3 g net carbs, thanks to its high dietary fiber content which subtracts from total grams of carbs. This is well within the carb intake range for ketogenic dieters.

Health Benefits of Summer Squash

Summer squash isn't just a great choice because of its low carb content. It's also a good source of fiber and packed with important nutrients like Vitamin C, which supports immune health and fights off free radicals.

One serving of summer squash can provide up to 30% of your daily values of Vitamin C. This makes it a great source of vitamin C for your keto diet. It's also a good source of beta-carotene, which supports eye health.

How to Incorporate Summer Squash in Your Keto Diet

Summer squash can be enjoyed in a variety of ways, making it a great addition to your favorite recipes. Here's a really easy recipe that transforms this type of vegetable into a tasty keto side dish.

Crispy Parmesan Summer Squash


  • 2 medium zucchini
  • 1/2 cup grated Parmesan cheese
  • 1/2 cup pork panko or crushed pork rinds
  • 2 tbsp olive oil
  • Salt and pepper to taste
  • Sour cream for serving (optional)


  1. Preheat your air fryer to 375°F.
  2. Slice the zucchini into 1/2-inch rounds.
  3. In a small bowl, combine the Parmesan cheese and pork panko.
  4. Dip each zucchini round into the olive oil, then coat in the Parmesan-pork panko mixture.
  5. Place the coated zucchini rounds in a single layer in the air fryer.
  6. Cook for 10-12 minutes or until golden brown.
  7. Allow to cool slightly before serving with sour cream if desired.

Incorporating Summer Squash into a Keto Meal

A great way to enjoy summer squash on a keto diet is to consider it as a main dish. The mild, slightly sweet and nutty flavor of summer squash makes it a versatile ingredient that can be incorporated into your keto meal in numerous ways.

For instance, spaghetti squash, a type of summer squash, is a fantastic low-carbohydrate alternative to traditional pasta. This yellow squash can be roasted and shredded into noodle-like strands. Toss it with a low-carb sauce and you have a keto-friendly spaghetti!

The Importance of Portion Size

While summer squash is a great option for keto dieters, like all foods, it's important to monitor your portion size. Overeating even low-carb foods can impact your weight loss journey and blood sugar levels. Try to keep your serving size to about a 1-cup serving for most low-carb vegetables like summer squash.

Summer Squash vs. Other Squashes

When it comes to keto-friendly vegetables, it's worth noting the difference between summer squash and other squashes, like butternut and acorn squash. These fall and winter varieties tend to have a higher carb content due to their starchy nature and natural sugars. So, while they can still be included in a keto diet in small amounts, they are not as keto-friendly as summer squashes.

The Best Way to Cook Summer Squash for a Keto Diet

Cooking summer squash is a breeze! You can simply slice it and sauté it over medium-high heat with a bit of olive oil until it turns golden brown. For an extra punch of flavor, add some cheddar cheese on top and let it melt to perfection.

Air fryer recipes are another great option. One of the popular recipes is Air-fryer Squash Parmesan — crispy-coated slices of yellow squash topped with Parmesan cheese and served as a friendly side dish or even a main dish.

Creating a Squash Mixture

One of my favorite ways to enjoy summer squash is by creating a squash mixture. You can combine different types of summer squashes, like yellow squash and zucchini, add in some leafy greens, olive oil, and spices, and sauté everything together. This creates a flavorful, low-carb side dish that pairs well with any protein.

Storing Summer Squash

Storing summer squash correctly is crucial for maintaining its freshness. Keep it in an airtight container in the refrigerator, and it should last for about a week. If you've cooked your squash, it can be stored in the refrigerator for three to four days.
