    🫑 Bell Pepper Facts

    Because we are science nerds we wanted to give a little background into bell pepper so here we go...Whenever we think of foods rich in vitamin C, our 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.

    vitamin c chart for a bell pepper 95.7 mg per 100g

    vitamin c chart for oranges. 53.2mg per 100g

    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.

    We always feel our best when we try to incorporate a variety of colors into our diet, which we 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:

    1. First, you'll slice the tops off of your bell peppers and scoop out the seeds.
    2. Next, you'll make your filling on the stovetop.
    3. After that, you'll stuff the peppers with the filling and top with cheese.
    4. 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.

      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!

      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.

        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.

      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.

        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.

      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!

      I just made this recipe and it is great. It’s definitely a keeper and it’s pretty easy to make with ingredients I have on hand. I put a layer of cheese in the middle of the pepper, too. And since I grow parsley I added several tbsp of fresh parsley to the meat mixture.

      When browning the beef, I usually drain the fat, but this recipe doesn't say to do that. What do you do with the excess fat liquid, just leave it in? Making now, hopefully you'll be able to direct me on how to proceed. Thanks!

      I love these, have been making them for about 5 years. Sometimes I leave the riced cauliflower out completely. My adult kids love them so when they get hungry for them I always make them.
      They are also good with cut up mushrooms in it too!

      I'm getting ready to make these for the 3rd time in a month! That means they are good. Actually, I only cook for myself so last time I stuffed 2 peppers, placed remaining stuffing in a small casserole dish, and cooked it along with the peppers. Freezes perfectly and later very good with steamed broccoli, etc. Thanks for something so taste satisfying.

      Great recipe. I added sour cream to the filling before I stuffed the peppers to make it even more delicious. Also recommend steaming the peppers in microwave for few minutes to soften them up before stuffing and putting in oven.
