How many carbs in a squash casserole?

Squash casseroles are a delicious and comforting dish that are popular in the fall and winter months when squash is in season. But if you are on a low-carb or keto diet, you may be wondering just how many carbs are in a typical squash casserole recipe.

The number of carbs in squash casserole can vary greatly depending on the specific ingredients used. Some recipes pack in starchy binders like breadcrumbs or flour to hold the casserole together, while others rely more on the natural starch in the squash itself. Cheese, cream, and other keto-friendly ingredients can help keep carbs lower.

Carb Count in Popular Squash Casseroles

Here is the carb count for some popular squash casserole recipes, per 1/6th or 1/8th casserole serving:

  • Classic Squash Casserole with Ritz Crackers: approximately 15-20g net carbs
  • Squash Casserole with Cream Cheese and Cheddar: around 8-12g net carbs
  • Low-Carb Squash Casserole with Almond Flour: roughly 5-8g net carbs
  • Keto Squash Casserole with Parmesan Cheese: around 3-5g net carbs

As you can see, the carb count can range significantly based on the specific ingredients used in the recipe.

Factors that Impact Carbs in Squash Casserole

Here are some of the main factors that determine how many carbs are in a squash casserole:

Type of Squash

Winter squashes like butternut, acorn, and pumpkin tend to have a higher natural starch and carb content than summer squashes like zucchini or yellow squash. For example, 1 cup of cubed butternut squash has around 23g of carbs, while 1 cup of cubed zucchini has just 4g of carbs.

Added Starches

Many traditional squash casserole recipes rely on added starches to bind everything together and help create that creamy texture. Common sources include flour, breadcrumbs, crackers, cornbread, rice, and potato. Going light on starchy binders or skipping them altogether can reduce carb count.

Dairy and Cheese

Cheese, heavy cream, cream cheese, sour cream, and butter all add delicious flavor and creaminess to squash casseroles, without spiking carbs. Prioritizing these keto-friendly dairy ingredients over starchy binders can help minimize carbs.

Nuts and Seeds

Crushed nuts and seeds can also help create texture and flavor in low-carb squash casseroles, while adding nutritional value. Try raw almonds, pecan pieces, pumpkin seeds, sunflower seeds, or nut meals/flours.


Some sweetener is often added to help balance out the savory flavor of the squash. Sugar will obviously increase carbs, so go for lower-carb alternatives like erythritol, stevia, or monk fruit.

How to Make a Low-Carb Squash Casserole

Here are some tips for keeping carbs down in your squash casserole recipe:

  • Use lower-carb winter squash varieties like pumpkin, spaghetti, acorn, or butternut.
  • Skip starchy binders like flour, breadcrumbs, rice, crackers.
  • Load up on cheese, cream, butter for richness.
  • Consider an almond or walnut flour crust/topping.
  • Use crushed nuts or shredded coconut for crunch.
  • Flavor with garlic, onion, herbs, spices, stock.
  • Sweeten with erythritol, stevia, monk fruit, or small amounts of maple syrup.

Common Questions about Carbs in Squash Casserole

Is squash keto-friendly?

Winter squashes like pumpkin, butternut, and spaghetti squash can be incorporated into a keto diet in moderation. They have more natural sugars and carbs than summer squashes, so portions need to be controlled. Always account for squash carbs when tracking your macros.

Can I make squash casserole without cheese?

It’s best not to skip the cheese in low-carb squash casseroles. Cheese helps make up for the lack of starchy binders and gives the casserole a creamy texture. Try vegan cheese substitutes made from nuts if you avoid dairy.

What can I use instead of crackers on squash casserole?

Great low-carb alternatives to cracker toppings include crushed pork rinds, parmesan cheese crisps, chopped nuts, seeded pepitas, or crushing up keto-friendly crackers. You can also skip the topping entirely.

Is almond flour keto-friendly?

Yes, almond flour is a popular keto-friendly substitute for regular flour. It does still contain some carbs from almonds but much less than regular flour. Use it sparingly and account for net carbs.

Is sweet potato casserole low carb?

No, sweet potato casserole is high carb since sweet potatoes have a lot more natural sugars than winter squashes. Try making it with pumpkin or butternut squash instead.


When it comes to squash casserole, carb counts can range significantly based on ingredient choices. Limit starchy binders, load up on low-carb veggies, cheese, and rich dairy, and minimize added sugars. With some keto substitutions, you can enjoy delicious low-carb squash casserole on your ketogenic diet. Focus on keeping portion sizes reasonable and rounding out meals with other low-carb foods like proteins and non-starchy vegetables.
