I love to whip up an easy frittata with anything I have in my fridge. In the summer, this tomato and zucchini frittata was something I came up with when I had to use up my garden veggies. Another summer frittata I make with zucchini is this Caramelized Onion, Zucchini and Red Pepper Frittata.

Summer tomatoes are abundant and delicious right now – my garden is overflowing with them! I’ve been enjoying them in tomato salads and quick garden sauces, over grilled flank steak, and in my egg sandwiches. But today I wanted to make something different, using up some zucchini that I bought at the farmer’s market this weekend and I came up with this delicious frittata.

What I love about frittatas is that you can enjoy them for any meal and they are so inexpensive to make. Today’s leftovers from lunch are going to be tomorrow’s breakfast. Perfect for meatless mondays, gluten free, clean eating and low carb diets. Also great for meal prep.

To Meal Prep

Divide into 4 meal prep containers. Keep covered and refrigerate for 3 to 4 days. To reheat, microwave in 30-second intervals until heated through.

Tips and Variations

  • To cut the zucchini into matchsticks, cut the zucchini in half and trim off the ends. Slice them lengthwise into 1/4-inch thick slices, then cut the slices into thin matchsticks.
  • Swap out the Asiago cheese for Parmesan or Pecorino Romano.
  • Add some baby spinach to the mix of veggies for added nutrition.

Garden tomatoes, summer zucchini, and Asiago cheese make a scrumptious frittata that highlights the end of summer's bounty.

  1. This was good! The whole thing really had a “garden fresh” vibe and taste to it, where the actual vegetable tastes were predominant. I had mine with some hot sauce for an extra kick.

  2. I was scared to try this because I don’t eat egg often and I was skeptical about the cooking process. However, it was easy to make and taste great. I did not make the zucchini too small, so I use 7 whole eggs instead of 5 eggs and 2 egg white. It still was under 200 calories per serving. I was happy with results and will make again

  3. Loved this frittata! Will definitely be making on the regular for a healthy breakfast during the week. I did make a few modifications. I used feta instead and I tried with one less egg and additional egg whites. I also added chopped fresh basil on the top, so yummy!

  4. I just made this and I am out of town at a rental house. Didn’t appear that any of the skillets were oven proof. So I saute’d the onion and zucchini in a skillet and then poured it into a big glass pie dish, then poured the egg/cheese mixture over top. I cooked it for about 5-6 min to let it set up a little bit, then added the sliced tomatoes and some fresh basil. It looks picture perfect and tastes great! I substituted fresh romano. Another winner!

  5. A very nice combination of flavors. I love the diversity of frittatas, and using tomatoes with zucchini is a great version!

  6. This recipe is such a good reminder that healthy, simple food can taste great. I honestly thought this would be bland, but it’s DELICIOUS! I doubled the recipe and used a 12″ cast iron to make 8 servings. I used 8 Eggs, no egg whites, and Parmesan instead of asiago. We have a julienne slicer, but even that still felt tedious, next time I will experiment with different forms of zucchini (chopped vs food processor, etc.). Can’t wait to make this again. Highly recommend.

  7. Very good and adequate portion size. Let’s be honest – in some recipes low calories come from tiny portion size. I did sprinkle chopped dill over frittata just before serving. Fresh, delicious and filling.

  8. I added 1 cup of fresh baby spinach leaves to the recipe….very nice and easy recipe! Will definitely make it again. Great Brunch, paired it with fresh fruit and coffee!!!

  9. I am just trying everything in the meal plan and this breakfast did not look too exciting. But honestly, it was good and… very filling. I added 2 table spoons of chilli and tomato relish… delish! Loving your recipes.

  10. This was great! I spiralized the zucchini and then chopped it up. It was much quicker that way. I also don’t have an oven proof skillet so I transferred it into a glass baking dish sprayed with olive oil cooking spray and increased the cooking time in the oven to 25 – 30 mins (until it was set and no more liquid). Worked perfectly!

  11. This was great for a casual Sunday evening dinner; the whole family including grandkids gave it rave reviews. The flavors came together so well and it was really easy to put together. To round out the meal I served the frittata with fruit and grits as sides The only thing I changed was to cut the zucchini into ribbons with the Vegetti.

  12. Sounds delicious! Has anyone made this recipe without any cheese? still good? or is there something else (perhaps extra seasoning?) that I could add instead?

  13. Hi Gina… this reminds me of the frittata that my grandmother use to make… Made this one last night and it was delcious. and easy to make… Love all your recipes..

    Thank you for sharing them with us.

  14. Delicious! I added a little fresh cilantro to the egg mixture, yum, yum yum!

  15. I made this recipe and substituted 1/4 c part skim ricotta for the Asiago.  It was completely delicious!

  16. This was my first Fritata and it was so easy to make, turned out beautiful, and was delicious. Made it for my Labor Day brunch and can’t wait to enjoy it for my breakfast the next 3 days. Your recipes are scrumptious and meal planning is a breeze. Have lost 70lbs since January and 30 more to go! Skinnytaste makes it easy!

  17. This tastes so good! The zucchini gives it a hardiness that I love. Gina, thank you so much for getting me out of a rut. I would never even consider making zucchini matchsticks if it were not for you!

  18. Hi Gina….I love your recipes and meal plans!! I’d like to make this frittata, and wondering  if I could spiralize the zucchini and cut it into smaller pieces.  I would be too impatient to cut it into matchsticks!! 
    Thanks, Jan

  19. I would like to make this recipe but I don’t have a pan that can go in the oven. Any suggestions?

  20. Can I make this in a pie pan instead of a skillet?

  24. We need to make this dairy – what could we use instead of cheese? Could we add some flax milk?

  26. Love this recipe! I have made a couple of times,, question I have a ton of yellow squash that someone gave me from their garden, do you think I could use that instead of zucchini?

  29. Just made this and it was delicious!  I used Parmesan Romano cheese instead of Asiago and I baked in muffin tins for individual servings. 375 for about 12-14 minutes. I will freeze some for later. Another fabulous recipe Gina!!!

  30. Just made this for breakfast this morning. I didn’t have zucchinis (go figure!) so I substituted with yellow bell pepper.
    One word: AWESOME!
    This one is a keeper.

  31. mmm…eggs

  32. I highly recommend this frittata recipe! It was my first attempt at making one and it turned out perfectly! I used Sargento Light Italian four cheese blend and grated parmesan romano in place of the asiago. is my first choice for great tasting light recipes!

  33. I made this for dinner tonight and it was delicious! I added a purple bell pepper and used parmesan because it was what I had on hand. Next time I think I'll add fresh basil too. Thank you for making my Weight Watcher' s journey so much fun!

  34. Can I shred the zucchini?

  35. Looks and sounds amazing! Can't wait to try it. Do you think this will freeze/thaw well?

  36. I don't know if my skillets are heat safe to 400 degrees in the oven. Can this be made in something other than a skillet when you get to the oven part?

  37. This is in the oven right now. It's going to be great!

  38. I always get the salt and pepper wrong in my eggs…but this seems to be a good way for me to get the taste right. I could also add some seasoning to the veggies to get some nice flavor to it.

  39. This was great! We didn't have asiago, so I substituted reduced-fat cheddar. Delicious and filling!

  40. Just made this and it was delicious!! You are my go-to food blog for everything! Thanks for yet another yummy, easy, and healthy recipe!!

  41. Yum! I just made this and it was delicious! My 2 year old son is usually picky about egg dishes and he gobbled it right down! I sprinkled some extra asiago cheese on top, too. Definitely going to make again!

  42. Made this last night for breakfast for the rest of this week…it turned out so beautiful, I almost ate some last night! 🙂 But resisted until this morning and it was DELICIOUS! Such great flavors. Thank you for all of your amazing recipes!!!

  43. Made this with feta cheese and put it directly in the oven for 30 min. It was perfect! Love your recipes, Gina!

  44. I need to buy a new skillet…. can you recommend a good one for going from stove top to oven, and also non-stick? Thanks!

  45. This looks so delicious, and so healthy! I love asiago cheese, mmmm

  46. I don't have an oven proof pan, nor an oven big enough to fit a pan. So I did the whole thing on the stove as was described, then transferred the veggies from the pan, gave them a swirl in a preheated tart tray (so I didn't have to oil/butter the tray), added the egg/cheese mixture on top of that, topped it off with the tomato and stuck it in the oven a little bit longer than described (about 20-25 minutes). Worked great! Thanks for the recipe.

  47. Would this still work if you put it directly in the oven vs on the stove top first?

  48. This is such a delicious, simple recipe! I made this with fresh vegetables from the farmers market and added some fresh basil on top and I really loved it. Your recipes are always great – thank you!

  49. I made this for dinner tonight with my bounty from the farmer's market. Delicious! Thank you for sharing your great ideas.

  50. I hate to waste food, so I was thinking about making this using four eggs and egg beaters for the whites. That would work, wouldn't it? I think egg beaters is just egg whites, right?

  51. I enjoy your recipes and can't wait till I have the money and ingredients to try them. They all sound and look delicious.

  52. Just wanted to tell you yet again how much I enjoy your many recipes. I'm a weight watcher member and it helps so much that you include the point value on every recipe.
    I'm so thankful that I found your blog1


  53. I wonder how feta cheese would pair with this? I might experiment!

  54. Made this last night and it was delicious — very flavorful! Also it scaled down easily. I only wanted enough for one dinner and one lunch! I substituted Parm for the asiago.

  55. Can you say how much I would need if I were using Egg Beaters instead of the traditional eggs/egg whites?

  56. I have the same question as NanaJo….

  57. Frittata's really are perfect for anytime. One of the most perfect foods! Plus, they are pretty easy and can utilize leftovers just like you said. Bonus points.

  58. How do you cut the zucchini in the matchsticks?

    • I slice them into 1/4 inch thick slices. Then I take those slices and cut them across into 1/4-inch wide pieces.

  59. Just curious why the recipe calls for 4 whole eggs and 4 egg whites?

    • I like to cut back the egg yolks to lighten it, and this is the perfect ratio. If you don't care about the extra calories, just use whole eggs.

    • So if we do not use the egg whites would we do 8 whole eggs or still just four?

    • Four egg whites if you want to lighten it up. Replace that with the whole egg if you don't care about fewer calories,

  60. droooling!


  61. Holy cow! Were you reading my mind with this one? I was just telling a coworker that I need a dinner idea that uses zucchini, tomatoes, and eggs since my fridge is overflowing with all of the above. You're awesome!

  62. I will be trying this, never made a frittata before but this looks delicious

  63. Perfect timing! I have three square planter boxes and we planted four tomatoes in each and we are now over run with tomatoes! Next year, we'll plant less for sure.

    Looking forward to trying this out.


  64. Does any skillet work- stainless steal vs cast iron (in oven?)


  65. Wow. This looks like it'll be dinner tonight! I don't have any asiago on hand, but I do have cheddar and goat cheeses. Either one of those sound better than the other in this recipe?

  66. looks delicious!

  67. This looks absolutely delicious! Think I may make this for breakfast soon 🙂

  68. I may not be a huge tomato fan, but this looks like it may convert me. Yum!

  69. I need to make this

  70. One great recipe after another….not an egg fan but would definitely try this one.

  71. What could replace it if I am allergic to zucchini?

  72. Just got done watering the garden and I'm still over flowing with zucchini. This looks like the perfect solution 😉
