Kale and Feta Breakfast Casserole from KalynsKitchen.com

This time of year I wonder if I should apologize to readers who don’t have a vegetable garden, because when my garden is producing certain veggies in abundance, it’s hard for me to think about cooking anything else. Right now it’s all about green beans, cucumbers, zucchini and kale, although eggplant and tomatoes are coming soon.

Kale is a vegetable I didn’t have much appreciation for until I started growing it myself, but now I love this ultra-nutritious vegetable.  When I thought of using kale and Feta in an egg casserole, I wasn’t sure how those two strong flavors would work together, but the combination in this Kale and Feta Breakfast Casserole was definitely a winner.  If you like kale but aren’t a fan of feta, you could use a blend of milder white cheeses like I did in Red Kale and Cheese Omelet for Two.

Chop up a generous bunch of fresh kale.  I used Red Russian Kale the first time, but I’ve since made this with darker green kale and it was just as good with the Feta. Saute the kale in olive oil just until it wilts and starts to soften, about 3-5 minutes.  (Darker kale will take longer to soften.) Put the sauteed kale in the bottom of a sprayed casserole dish. Sprinkle over a generous amount of crumbled Feta cheese.

Beat 12 eggs with some Spike Seasoning or an all-purpose seasoning of your choice and a little salt and fresh ground black pepper. Pour the eggs over the kale and Feta; then use a fork to gently stir so ingredients are evenly distributed in the eggs. Bake at 375F/190C for 40-45 minutes. The casserole will puff up as it cooks, but it settles own nice when it cools a few minutes! Serve hot.

Kale and Feta Breakfast Casserole

This Kale and Feta Breakfast Casserole is one of the simplest recipes ever, but the combo of kale and Feta is a winner.


  • 10-12 oz. fresh kale, washed and coarsely chopped
  • 2 tsp. olive oil
  • 3/4 cup crumbled Feta cheese (about 4 oz.)
  • 12 eggs, beaten
  • 1 tsp. Spike Seasoning (or use any all-purpose seasoning that’s good with eggs)
  • Salt and fresh-ground black pepper to taste


  1. Preheat oven to 375F/190C.  Wash the kale if needed and spin dry or dry with paper towels, then coarsely chop kale.
  2. Heat oil over medium-high heat in a large frying pan.  When oil is hot add the kale and cook while stirring until kale is wilted and starting to soften, about 3-5 minutes.  (Red Russian Kale will cook more quickly; darker green kale varieties will take longer to soften.)
  3. Spray a 9″ x 12″ casserole dish with olive oil or nonstick spray, then put barely-cooked kale in the bottom of the dish.  Crumble Feta cheese over the kale.
  4. Beat eggs with Spike Seasoning, salt, and fresh ground black pepper; then pour eggs over kale/Feta.  (I like to take a fork and gently stir so the veggies and cheese are well-distributed in the eggs.)
  5. Bake the casserole 40-45 minutes, or until eggs are set and the top is starting to lightly brown.
  6. Serve hot. This is good with a dollop of sour cream.


Leftover egg casserole will keep in the fridge for about a week.  Reheat in the microwave for 1-2 minutes.  (Don’t microwave too long or it will make the eggs rubbery.)

  1. I've never made it with anything but whole eggs, but I'm sure it will work with whatever you prefer.

  2. this recipe looks so good as im starting to cook my bfasts for the week, I was wondering would I be able to substitute egg whites for the full eggs, or maybe just do half and half? what do you suggest?

  3. Michelle, glad you guys enjoyed it.

  4. I halved this into an 8×8 dish so but I had to use 7 eggs to make the kale covered. I enjoyed this so much as well as my husband (surprisingly!) Yum!
