This tasty Roasted Green Pepper and Tomato Breakfast Casserole with Feta and Oregano is a recipe I created back in 2010 when I was just making something to eat, and then it turned out so well I decided to make it again and take photos for the blog. It was inspired by one of those big plastic containers of cherry tomatoes from Costco, and my habit of buying those big containers regularly is one of the reasons I’ve kept making this so often through the years.

It seems I can rarely manage to use all the tomatoes before they start to shrivel, and when I was thinking about what to do with slightly-shriveled cherry tomatoes I hit on the idea of roasting them for a breakfast casserole. There was a green bell pepper in the fridge that was begging to go into this, and adding some dried oregano and feta cheese gave it a bit of Greek flavor. I’ve made a lot of low-carb breakfast casseroles through the years, I think this combination is definitely a winner, and I’m happy it’s finally getting better photos so people are more inspired to make it.

If anyone is wondering why I’m making breakfast casserole when it’s 90 degrees in the shade, I cooked it in my Oster Toaster Oven! Cut the green pepper into short strips, brush baking dish with olive oil, then sprinkle with oregano and roast in a 375F/190C oven for about 10 minutes. Then add the cut tomatoes, and stir to distribute. Roast about 15 minutes more, or until the tomatoes are starting to look a bit shriveled like this.

Sprinkle crumbled Feta cheese over the roasted tomatoes and bell pepper. Pour over the beaten egg that’s seasoned with Spike Seasoning, salt, and fresh ground black pepper. (I always stir this a little to get the ingredients well-distributed in the egg.)

Bake the casserole about 30-35 minutes (or a bit less if you use a shallower dish than I did), or until the top is lightly browned and eggs are set. (It will puff up a bit like this when it first comes out of the oven, but it settles down after it cools for a few minutes.)

Serve Roasted Green Pepper and Tomato Breakfast Casserole hot; this is good with a little sour cream to add at the table if you’re a sour cream fan.

Roasted Green Pepper and Tomato Breakfast Casserole with Feta and Oregano

This delicious low-carb breakfast casserole has all the flavors of summer!

Ingredients:

  • 1 green bell pepper, seeds removed and cut into thin strips
  • olive oil, for brushing baking pan (or use nonstick spray)
  • 1/2 tsp. dried oregano (optional, but good)
  • 1 cup cherry tomatoes, sliced in half (This is a perfect way to use those last tomatoes that are getting a bit shriveled)
  • 1 cup crumbled Feta cheese (more or less to taste)
  • 10 eggs
  • 1 tsp. Spike Seasoning
  • salt and fresh ground black pepper for seasoning eggs

Directions:

  1. Preheat oven or toaster oven to 375F/190C.
  2. Brush 9″ x 13″ (or similar size) baking dish with olive oil, including the sides, or spray with nonstick spray.
  3. Cut out seeds from green pepper, then cut into short thin slices.
  4. Put green pepper into baking dish, sprinkle dried oregano over, and roast for 10 minutes.
  5. While green pepper roasts, cut cherry tomatoes in half. Break eggs into a bowl and beat until egg yolks and whites are well combined.
  6. Season eggs with Spike Seasoning, salt, and fresh ground black pepper.
  7. After peppers roast for 10 minutes, add cut cherry tomatoes and stir to combine.
  8. Put dish back in oven and roast 15 minutes more, or until tomatoes start to look slightly cooked.
  9. Sprinkle Feta cheese over roasted peppers and tomatoes, then pour beaten eggs over. (I used a fork to stir slightly so the roasted peppers and tomatoes were evenly distributed in the eggs.)
  10. Return pan to oven and cook for about 30 minutes, or until the top is lightly browned and eggs are set. (I had a deep dish, so if you’re using a flatter dish it will take less time.
  11. It will puff up a bit when it cooks, but after it cools for a few minutes the casserole will settle.)
  12. Serve hot.
  13. This is good served with a dollop of low-fat sour cream or plain yogurt.
  14. This casserole can be kept in the fridge and reheated in a microwave, but be careful not to microwave too long or the eggs will get rubbery.

This recipe created by Kalyn when she had a surplus of cherry tomatoes that needed to be used!

  1. Hi
    Your SBD breakfast recipes look amazing! I just have a couple questions. I do shift work and I'm employed full time. If precooked the egg recipes, how long would the last in the refrigerator? My plan is to cut some up each time I'm working when I need breakfast. Also, I'm not a huge fan of feta, can you recommend any other cheese that may be nice in these recipes? thank you so much

  2. Egg casseroles will last at least a week in the fridge. You can even cut them into serving-size pieces and keep in individual containers; then just pull one out and microwave each morning. Any type of low-fat cheese will work; I use low-fat grated mozzarella quite a bit.

  3. This was excellent! I love how you can do all three steps in one pan…making the clean up super easy. I don't have spike seasoning so in place I use Trader Joe's Seasoning Salute. Delicious!

  4. Michael, so glad you enjoyed!

  5. This is a burst of flavors! Especially I love the combination of cheese and tomatoes always.

  6. Call me stupid-I can't figure out where your Yummly button is?????

  7. This is one of the most nutrient-dense casserole I've seen! I will definitely give it a try! Can I use regular tomatoes?

    • Glad you like it. Cherry tomatoes are not quite so juicy, so if you use regular diced tomatoes I'd drain them in a colander while the peppers are roasting. Hope you enjoy!

  8. I didn't know that a veggie recipe could be so tasty! Thanks for sharing with us!
