This delicious, seasonal frittata will not disappoint your tastebuds. Enjoy butternut squash while it’s at its best and in season!

This frittata is unusual because it is actually quite sweet. While the eggs, potatoes, and the small amount of cheese provide a solid, savory base, the butternut squash and onions, which caramelize just beautifully in the oven, add an unexpected yet welcome sweetness.

There’s just something about sweet and salty which is just… perfect.

Key Ingredients 

  • Potatoes. Any potato will work in this recipe.
  • White Onion. Cooked onion adds the perfect sweetness to this dish.
  • Butternut Squash. Adds a sweet and savory flavor to this frittata.
  • Eggs. Eggs are the foundation of a good frittata. Use fresh large eggs.
  • Fresh Rosemary. This herb really brings out the fall flavors without overpowering the dish.
  • Cheese. Every frittata needs a little cheese. Use a cheese that melts easily like cheddar.

Step-by-Step Instructions

1. Preheat the Oven. Preheat the oven and heat olive oil in a large skillet.

2. Prepare the Vegetables. Slice the potatoes into thick slices. Peel the onion and slice it into thick rings. Use a vegetable peeler to slice the butternut squash into “ribbons.” You can chop the butternut squash into small squares if you prefer.

3. Cook the Vegetables. Using a skillet, add some oil and sauté the potatoes until they begin to go soft, then add the onions until they are translucent.

4. Prepare the Eggs. Beat the eggs together in a large bowl, season with salt and pepper, and add the fresh rosemary and set aside.

5. Add the Butternut Squash. Once the onions are translucent, add the butternut squash to the pan and arrange everything so it is lying flat in the pan.

6. Add the Eggs. Pour the egg mixture evenly over the top to allow the egg mixture to fill all the gaps. Grate some cheese directly on top of the frittata.

7. Bake. Bake in the oven until the top turns golden brown. Serve immediately.

Recipe Tips, Variations, and Substitutions

  • Use sweet potato instead of butternut squash. If you do not have butternut squash you can use sweet potatoes for a similar flavor.
  • Cheddar cheese. Use a classic cheese that melts easily like cheddar cheese or gouda, for the best flavor.

Storage Recommendations

Store leftover frittata in an airtight container in your fridge for up to 4 days. Reheat the frittata in your oven until heated through.
