I love the Power Greens mix of chard, kale, and Spinach I’ve been getting at Costco. And if you know my food preferences at all, you might not be surprised that this Power Greens Breakfast Casserole is one of the things I love making with this  delicious mix of greens. And I used Feta and Mozzarella to make this a cheesy breakfast casserole that’s loaded with flavor.

When I first made the recipe for myself, I made this four times in a row, so that’s a sign of how much I like it! Then one weekend my foodie friend Sean stayed at my house when he was in town, and when I fed him some of the leftovers for breakfast, he gave the recipe a thumbs up. That’s when I realized I needed to take some photos and share this recipe on the blog!

I actually used a full pound of the power greens mix in this, which helped balance out the generous amount of cheese! I think the combination of cheeses here went really well with the greens, so if you like the idea of starting out the day with a healthy dose of greens, give this a try!

What are Power Greens?

Power Greens is a brand name for a bagged mix of greens that contains chard, kale, and spinach, and sometimes a few other greens. You can use any healthy mix of greens you prefer for this recipe.

Can you use other types of cheese for this recipe?

I did love the combination of Feta and Mozzarella that made a delicious cheesy Power Greens Breakfast Casserole. But if you’re not a fan of those cheese or have another cheese on hand, any type of white cheese that melts well will taste great here.

How to make Power Greens Breakfast Casserole:

(This is just a summary. Scroll down for complete printable recipe including nutritional information.)

  1. I buy the Power Greens mix from Costco, but when I googled it, I found there were lots of companies making a similar mix of greens.
  2. Heat a little olive oil in a large, deep frying pan and add the greens all at once.
  3. Then use a large turner to keep turning the greens over and over until they’re all wilted down.
  4. Put the wilted greens in a large glass or ceramic casserole dish that you’ve sprayed with olive oil or non-stick spray.
  5. Spread the crumbled Feta, cubes of mozzarella, and sliced green onion on top of the wilted greens.
  6. Season to taste with fresh-ground black pepper and Spike Seasoning (affiliate link) or use your favorite seasoning blend that’s good on eggs if you don’t have Spike.
  7. Beat the eggs until yolks and whites are well-combined and then pour over the greens and cheese.
  8. I like to use a fork and “stir” the mixture so the top of the casserole shows all the ingredients.
  9. Bake at 375F for about 40-45 minutes, or until it’s as browned as you like it, then serve hot.
  10. I use this container with a snap-tight lid to keep leftovers in the fridge so I can enjoy this for breakfast for several days after I’ve made a big casserole like this one.

  • 1 lb. power greens mix (see notes)
  • 2 tsp. olive oil (more or less, depending on your pan)
  • 6 oz. mozzarella cheese, cut in 1/2 inch cubes (see notes)
  • 4 oz. Feta, crumbled
  • 1/2 cup sliced green onion
  • Spike Seasoning to taste
  • fresh-ground black pepper to taste
  • 14 eggs


  1. Preheat oven to 375F/190C. Spray a large glass or ceramic casserole dish with olive oil or non-stick spray. (My dish was 10″ x 13″; if you don’t have a dish that’s close to that size I would cut down the recipe a bit.)
  2. Heat a little olive oil in a large non-stick frying pan with high sides. Turn heat to high, add the greens all at once, then immediately use a large turner to turn greens over and over until they’re completely wilted down. (This will only take a minute or two, watch them carefully.)
  3. Put the wilted greens in the bottom of the casserole dish.
  4. Cut the mozzarella into cubes about 1/2 inch square (or you can use grated mozzarella, but I do like the nuggets of melted cheese from the mozzarella cubes.)
  5. Crumble the Feta and slice enough green onions to make 1/2 cup.
  6. Sprinkle the mozzarella, feta, and sliced green onions over the greens.
  7. Season the mixture to taste with Spike Seasoning (affiliate link) and fresh-ground black pepper. (Don’t use salt, the Feta is salty enough.)
  8. Beat eggs until the yolks and whites are well-combined, then pour over the greens/cheese mixture. Use a fork to gently “stir” the mixture so the greens, eggs, and cheese are evenly distributed.
  9. Bake 35-40 minutes, or until the mixture is completely set and the top is as brown as you prefer.
  10. Serve hot, with a dollop of sour cream if desired.
  11. This will keep in the fridge for at least a week, and it reheats well.


I used a blend of kale, chard, and spinach for this recipe. You can use any greens you prefer or have on hand.

Use reduced-fat or full-fat mozzarella, whichever you prefer.
