We grew a ton of butternut squash in our garden this year, so I’ve been having fun coming up with new recipes for it!

This was such a delicious brunch, and made enough servings so we were able to have leftovers for the week. An easy autumn breakfast everyone at the table will love!

What’s In This Vegetarian Butternut Squash Frittata Recipe?
See the recipe card below for full ingredient amounts and recipe instructions!
Onions, Kale, Butternut Squash
Worcestershire Sauce: for that unbelievably rich umami flavor, but make sure you use a vegan variety if you don’t eat meat (some can contain anchovies).
Herbes de Provence: my favorite spice blend! This French blend has a mix of rosemary, thyme, sage, and savory for a wonderful and complex flavor.
Extra virgin olive oil
Garlic Powder: Also a major pantry staple ingredient that gets used in our house daily! I love this garlic powder and add it to a lot of recipes that I would use fresh garlic in too.
Eggs – we get ours from the farm down the road, and if you can support your local farmers!
Milk of choice
Cheese, I used crumbled goat cheese
Smoked Paprika: give an additional depth of flavor to this dish.
How Do I Make This Vegetarian Frittata with Butternut Squash Recipe?
Preheat oven to 425 degrees Fahrenheit.
In a large 11 inch cast iron skillet, add the olive oil and onions. Sauté over low heat for about 10 minutes until they begin to brown. Add the diced butternut squash and sauté for an additional 10 minutes until the squash begins to soften.
Add the Worcestershire sauce, Herbs de Provence, garlic powder, kale, and stir well to combine.
Crack the eggs into a separate bowl, and add the cheese, milk, salt, pepper, and paprika. Whisk well until the eggs are well scrambled.
Pour the eggs mixture into the Cass iron skillet with the vegetables and quickly combine.
Cook the eggs in the skillet for 4 to 5 minutes until the edges set (do not stir).
Place the frittata in the oven and bake for 8 to 10 minutes until the top is lightly browned.
Remove from oven, allow to cool for 10 minutes, and slice to serve.
To make ahead or the night before, follow the above steps until the frittata is fully cooked. Cover with a plastic wrap, and refrigerate for up to a day. To reheat, place in a 350 degree oven for 15 minutes until hot.
