Bell Pepper Facts
Because we are science nerds we wanted to give a little background into bell pepper so here we go…Whenever I think of foods rich in vitamin C, my mind always goes to oranges because that’s just what we’ve been taught contains the most. But did you know that bell peppers have more Vitamin C than oranges?
100 grams of green bell pepper contains 95.7 mg compared to 53.2 mg in 100 grams of oranges.
It seems pretty impressive, right? Well, green bell peppers are just the tip of the iceberg. Yellow and red varietals contain even more with 341 mg and 209 mg respectively. And it’s not just vitamin C either. A large red bell pepper contains over 5000 IU of vitamin A whereas a large yellow bell pepper only contains 372 IU.
I always feel my best when I try to incorporate a variety of colors into my diet, which I call “eating the rainbow”. These Keto Stuffed Peppers are great for that!
Bell peppers are a great way to accomplish this on keto (green is easy) because yellow and orange are sometimes troublesome to fit within your macros. Depending on the time of year and availability you can also find bell peppers in brown, white, lavender, and dark purple.

Now, for some common questions:
How to make stuffed peppers:
- First, you’ll slice the tops off of your bell peppers and scoop out the seeds.
- Next, you’ll make your filling on the stovetop.
- After that, you’ll stuff the peppers with the filling and top with cheese.
- Transfer the peppers to the oven and bake until tender or until a fork easily pierces the side of the pepper.
What is in Keto Stuffed Peppers?
These have a meat mixture filling made with ground beef, olive oil, onions, garlic, diced tomatoes, Italian seasonings, and cauliflower rice. We also tucked in some cheese for good measure because cheese is so totally delicious. If you are dairy-free you can leave out the cheese.
Do I have to use a cast-iron skillet?
No, you can totally use a baking dish! Just be sure to choose one where all of the peppers touch so that they don’t tip over while baking.
Can I use ground chicken instead of beef?
Yes! Definitely. Feel free to swap any ground protein for the beef here. Turkey would also work great as would Italian sausage.
Can these be reheated?
Yes! These make a great meal-prep recipe. To reheat you’ll want to simply pop them in a 400° oven for about 10 minutes. The cheese will get nice and melty again, and let’s be honest. The cheese is the best part of any dish.
What is the nutritional information for these Keto Stuffed Peppers?
As always, you can find the full nutritional breakdown including the carb count (total carbs and net carbs) at the bottom of the recipe card and you can find the serving size/yield at the top of the recipe card. You should always double-check your specific ingredients because different brand’s ingredients may have different values.
For this recipe, each pepper is 10g net carbs.

Wonderful! Made them tonight. Will definitely make them again! Thanks for the recipe!
Thanks for the Recipe it was awesome 👌
Other than the cauliflower rice which I love this recipe seems pretty traditional .I have all the ingredients except the tomato paste Since I’m not doing Keto I’ll probably just substitute ketchup.I’m sure that will be OK .I’ll post some pictures when I get it done .
Made these for dinner a few weeks ago. Loved. loved. loved. them! =)
Is 1 pepper equal to 1 serving?
Yes
Fantastic!! These were great! My husband (who is picky and not on keto) loved them too! Thank you for the great recipe!
Will these stay good in the fridge for five days? I’d like to take one everyday for lunch this week but not sure if I should freeze them instead. Thanks
Hi Lucinda! Yes, they should be fine in the refrigerator for 5 days as long as they are stored in an airtight container and reheated properly.
Excellent, made them tonight, so easy!
Delicious and easy to prepare!
Hi the recipe looks delicious. However I presume you did not mean 114.5 oz of diced tomatoes. I followed my intuition and merely added 14.5- 28 oz of diced tomatoes. Thank you for creating these wonderful recipes for us. God bless.
Hi Louise, definitely not – the recipe calls for one 14.5 ounce can, I can see where it would be easy to read through real fast and read it as 114.5 ounces. So glad you didn’t use 114.5 ounces lol!
These were amazing and so easy!!!! I added a little Heinz sugar free ketchup on top before the cheese!!!
They were good but lacked something. I will make them again but will change it up a bit. Perhaps a little more paste and more seasonings such as Italian seasoning. Or use Rao marinara sauce instead tomatoes and paste.
Do I have to use avocado oil?
Nope, any oil you have on hand will be fine.
Can you use frozen cooked cauliflower rice?
Yes! We typically use Trader Joe’s frozen cauliflower rice and just thaw it out beforehand.
Can I use the diced tomatoes with green chiles? Or would that throw off the flavor completely?
I think that would be totally fine!
Carb manager says 10 Net carbs each, That seems high.
You can always adjust a bit, use less onion, use a different blend of cheese for less carbs, and lower the amount of cauliflower. Carb manager let’s you insert your own recipe and mine are only around 7 net carbs based on the spices/ingredients I used.
Made these tonight for Dinner and the flavor is outstanding and me and the wife loved them. This is def going in my recipe book. Thankyou
I think I’ll leave out the tomatoes, that’s where a big hunk of the carbs come from. 10 carbs is a lot for one item in the day on Keto.
Very Easy to make and great tasting.
Can these be frozen? I had too much ground beef so adjusted the recipe for that and ended up with 8 peppers . They are delicious but don’t want to eat them every day!
Hi Nina, we’ve had a few readers say that they have frozen them but we have not given it a try yet. In theory, they should be perfectly fine and you can reheat in a skillet or the oven.
These are easy and tasty, thank you!
These are absolutely amazing! I’ve never left a review for anything before, but I had to give these five stars. I’ve made many stuffed pepper recipes before, but this recipe far surpasses them all. Awesome recipe!
Do you mean “cover” with the pepper tops.?
Hi Mimi, no this means to cover with foil. Apologies that that wasn’t clear, hope this helps!
I was really pleasantly surprised. Very flavorful and filling. Adding it to the menu plan. Thanks!
Glad to hear it, Josh, thanks!
I thought these were delicious. Made them at first uncovered (in error and they were okay (missed the 10 uncovered) Remade them today and they are delicious! I actually think the cauliflower rice is better than regular rice… I am thinking if you keep the original instructions I believe they would be tasty with spices of your choosing and ANY type of cheese that you like or have on hand!
Great recipe! Thank you!
We just made these tonight after a full day of biking they were amazing expecting a 7 on 10 but there actually a 9.9 on 10 awesome thank you so much for the recipe I try to post a pic… I did add 1 cup of cheese and to Sun dried tomatoes this to make it my own
These were delicious out of the oven as well as the next day!
