This tasty Roasted Green Pepper and Tomato Breakfast Casserole 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

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.

Notes:

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

  1. My family loves eggs and feta-will be making this recipe very soon!

  2. Jeanette, that's exactly what I thought when I made it!

  3. What a great idea for an egg casserole – love Greek flavors, and this is a nice way to put the rest of this summer's tomatoes and peppers to good use.

  4. Melissa, so glad you liked it. I think asparagus would be great.

  5. This is YUMMY! I decided to cook it in a larger dish because when I got the green pepper in the bottom of the smaller dish it seemed like too much for me. I added 2 more eggs to compensate for spreading it out. I'm wondering how yummy this would be with asparagus instead of green pepper. I absolutely love asparagus and egg. Oh, and when I read the recipe I thought that bacon would be a perfect addition then I saw someone else asked about that too so I went ahead and added that to mine. This is such a keeper!!!! Thanks!

  6. Cameron, so glad you liked it!

  7. I'm eating some for breakfast this morning at work as I type this. My girlfriend and I have been loving your breakfast casseroles and this one is a special treat. Thanks!

  8. looks delicious.. breakfast cassaroles are always game with me, any day, any time! i wanted to plant a cherry tomato tree just for the reason that i can't seem to ever finish a box of cherry tomatoes from supermarket. this is a good recipe for leftover cherry tomatoes.

  9. This sounds soooooo tasty! I love all of the ingredients and agree that this is probably a GREAT way to use up the extra tomatoes in the carton. I can never finish one either 🙂

  10. This looks great Kalyn! We love a great egg casserole and are always looking for ways to add fresh produce. I love it when great recipes happen by accident.

  11. I love roasting veggies, brings out the best flavor. Great recipe!

  12. Dara, any time! That would be fun.

  13. Someday I am going to show up on your doorstep for breakfast. You make such wonderful egg casseroles!

  14. Martha, this will keep in the fridge for at least a week. (At the end of the recipe, I talked about how to reheat in the microwave.)

  15. Hi Kalyn,

    Will this keep at all? My husband isn't a fan of baked eggs, but this dish is right up my alley. If it will keep, I'll make it for myself and eat the left-overs.

    Thanks,
    Martha

  16. I love roasted veggies, too. They sound great in that breakfast casserole 🙂

  17. This looks good enough for dinner. Oh heck, any meal!

    I make your zucchini breakfast casserole all the time. This one will be on my list soon!

    Thanks again, Kalyn!

  18. I stopped by your blog today. This looks delicious.
    Ann

  19. I just made something like this with thinly sliced zucchini, yellow and red grape tomatoes, and a little bit of monterrey jack that had some olive and red pepper in it. I made it in a frying pan. I sauteed the vegetables in olive oil with a little bit of oregano and lemon pepper and then poured over the eggs. I helped the top set up by covering the pan at the end of cooking (after adding the cheese on top).
