To craft this Roasted Butternut Squash Soufflé, gather the following ingredients:

For the Soufflé:

  • 3 cups roasted butternut squash, mashed
  • 4 large eggs, separated
  • 1/4 cup unsalted butter
  • 1/4 cup all-purpose flour (or almond flour for keto version)
  • 1 cup whole milk (or unsweetened almond milk for keto)
  • 1/2 cup grated Parmesan cheese
  • 1/2 teaspoon nutmeg
  • Salt and black pepper to taste


1. Roast the Butternut Squash:

  • Preheat your oven to 375°F (190°C).
  • Cut the butternut squash in half, remove the seeds, and roast it in the oven for about 45 minutes, or until it’s tender.
  • Scoop out the flesh and mash it into a smooth puree.

2. Separate Eggs:

  • Divide the eggs, placing the yolks in one bowl and the whites in another. Set aside.

3. Make a Roux:

  • In a saucepan over medium heat, melt the unsalted butter.
  • Stir in the all-purpose flour (or almond flour for the keto version) and whisk continuously for about 2 minutes to create a smooth roux.

4. Add Milk and Seasonings:

  • Gradually pour in the whole milk (or unsweetened almond milk for keto) while continuing to whisk. Cook for about 5 minutes, or until the mixture thickens.
  • Season the sauce with grated Parmesan cheese, nutmeg, salt, and black pepper.

5. Combine Yolks and Squash:

  • In a mixing bowl, combine the mashed butternut squash with the egg yolks.

6. Mix the Squash and Sauce:

  • Carefully fold the butternut squash mixture into the prepared sauce.

7. Whip Egg Whites:

  • In a separate bowl, whip the egg whites until they form stiff peaks. This step is crucial for the soufflé’s fluffiness.

8. Combine and Bake:

  • Gently fold the whipped egg whites into the butternut squash mixture until well incorporated.
  • Pour the mixture into a greased soufflé dish and bake in the preheated oven for about 25-30 minutes, until the soufflé has puffed and is golden brown.

Cooking Notes 

  • Roasting the butternut squash adds depth and richness to the soufflé’s flavor.
  • When folding the egg whites into the mixture, be gentle to preserve the soufflé’s airy texture.


  • Enhance the soufflé with a sprinkle of crispy bacon bits or chopped fresh herbs like thyme or sage.
  • Experiment with different cheeses, such as gruyere or cheddar, for unique flavor profiles.

Keto Version  For a keto-friendly adaptation, replace the all-purpose flour with almond flour when making the roux. Use unsweetened almond milk instead of whole milk, and ensure your Parmesan cheese is keto-compliant. This keto version captures the essence of Roasted Butternut Squash Soufflé while staying faithful to your low-carb dietary goals.

Low-Carb Version To create a low-carb adaptation, utilize almond flour for the roux and unsweetened almond milk in place of whole milk. Confirm that your Parmesan cheese aligns with low-carb standards. This low-carb version allows you to indulge in the delightful flavors of Roasted Butternut Squash Soufflé while staying on track with your low-carb lifestyle.
