This simple, savory Roasted Butternut Squash and Bok Choy Frittata is dairy-free and perfect for breakfast or brunch. Cooks up in just 25 minutes!



  • ½ butternut squash, peeled, seeded and cubed
  • 1 tablespoon olive oil
  • ½ teaspoon salt
  • ½ teaspoon ground pepper
  • 2 tablespoons canola oil
  • ½ medium onion, chopped
  • 2 garlic cloves, minced
  • 34 green onions, sliced
  • 2 red Thai chili peppers, chopped
  • 2 heads baby bok choy, chopped
  • Salt and pepper
  • 9 eggs, beaten
  • Optional: Sriracha sauce for extra heat


  1. Preheat oven to 400 degrees. Place the cubed butternut squash on a baking tray and drizzle with olive oil, salt and paper. Toss well to coat. Place in the oven for 25 to 30 min., until the squash is fully cooked. Let cool on the rack. Lower the heat to 325 degrees.
  2. Meanwhile, heat the canola oil in medium cast iron pan over medium-high heat. Sauté the onions and garlic until translucent, about 3 min. Add in the green onions, chili peppers, and baby bok choy. Keep stirring until wilted, about 5 min. Toss in the butternut squash until combined. Sprinkle with salt and pepper.
  3. Pour in the beaten eggs, evenly distributing it, and cook until the edges start to set, about 3 minutes. Place the pan in the oven. Cook for about 25 minutes, or until the eggs are firm. Add more seasoning if desired.


  • Thai chili peppers can be somewhat seasonal. I can always find them at my local Asian market. I’ll freeze them in bulk so I can have them on-hand year round. If you can’t find Thai chili peppers, substitute with jalapeño peppers or some other spicy pepper.
  • Baby bok choy is loaded with nutrients. I use the baby variety because there aren’t any thick stems to deal with. Of course, you can always use the more mature bok choy, which is available at most grocery stores.
  • If you’re not on a dairy-free plan, add whatever cheese you’d like to this frittata! You can even just sprinkle some shredded cheese on top of the frittata right before it comes out of the oven.
  • I do prefer using a cast iron pan for my frittatas. However, if you don’t have one, use a heavy skillet that’s oven-proof.
  • Want it hotter? Drizzle the top with some sriracha sauce or your favorite hot sauce!
