Keto Stuffed Peppers with cheese on top. Heathy & Easy to make

A warm comfort food dish after a long and tiring day at work is all I need. It was such a great hit, and I had to share it with you. All my non-keto family members loved these colorful stuffed keto peppers, and there’s no wonder why.

The juicy flavored ground beef stuffing and the perfectly fresh peppers are packed with such great nutrients and vitamins.

One serving of my keto stuffed peppers provides 123% of the daily recommended intake of Vitamin C.


Let’s start cooking!

How to make keto stuffed peppers?

To make keto stuffed pepper we have to omit the rice that is usually used in the classing filling.

Shred your cheese

The pre-shredded cheese usually has added agents like potato starch to prevent clumping and has more carbohydrates.

I used aged cheddar cheese because it has a stronger taste, but you can use any kind of cheese you love.

Mozzarella would be a great substitute. Add more oregano and you will have a fabulous keto Italian meal without all the carbs from their classic bread and pasta dishes.

The ingredients, keto and simple

  • 3 Medium Peppers, any color you want. I loved the red and the yellow ones.
  • 1 pound ground beef
  • onion & garlic
  • 1 can diced tomatoes
  • 6 oz cheddar cheese
  • salt & seasonings to taste

Take care of the Peppers

Gently wash the peppers and remove all the seeds and membranes from the inside. Sprinkle some salt over them.

add the chopped onion in the keto melted butter

For the pepper’s stuffing, you will need to chop one medium onion and 2 cloves of garlic. Add them in a pan with 2 tablespoons butter over medium heat until it gets a nice golden brown color.

Use a food processor if you’re like me an cry like a baby when it comes to cutting onions.

After about 8 minutes it’s time to add the meat. While cooking, use a spatula break up the meat.

Seasonings, the most important part

I added pink Himalayan salt, chili powder, black pepper, dried oregano leaves. Let your taste buds guide you through this step. After adding the tomatoes add more seasonings if you feel like it.

This is how the mixture looks before I add the tomatoes. Smells and tastes amazing. I could easily just sprinkle some cheese on top and have a nice quick low carb lunch.

Tomatoes are a great source of Vitamin C, Vitamin A, potassium, manganese and provide tons of fantastic health benefits.

Don’t be afraid to eat tomatoes on a ketogenic diet.

One cup of tomatoes has only 4g NET carbohydrates.

Spoon 3-4 tablespoons stuffing in each pepper.

Sprinkle some cheese on top. Well, use all the cheese you want. Who am I to judge anyone’s cheese decisions? (just kidding.)

As all the meat is covered in delicious freshly grated cheddar cheese take these beauties to the preheated oven.

Have you tried my easy keto stuffed peppers recipe? Let me know how great they turned out in the comments below.

If you have any questions feel free to ask them. I am here to bring the best out of a keto diet.


  1. I just finished eating my first stuffed pepper, and it was DELICIOUS!!!! I only used 1 teaspoon salt and one teaspoon pepper, and it was perfect! Thank you for sharing the tasty recipie!

  2. I'm confused about the peppers and serving size. Is a serving size 1 full pepper whether green, red or orange. Therefore should the recipe say red, yellow or green? Or for the recipe for one serving do you need 3 whole peppers. I made it for six servings (1# ground beef) but only used 2 peppers cut in half. I'm trying to figure accurate carbs and fats. Love the recipe!

  3. Boil 2 green peppers until slightly soft. Mix 4 oz. fatty hamburger, 1 egg, 1/4 c low carb pizza sauce, tsp, garlic, T chopped onion, 1/4 c shredded cheese. Divide in half, in each pepper. Add 1 T. pizza sauce and cheese on top of each. Bake 350, 30 minutes. Very low carbs. Yummy!!

  4. Oh my! My family loved these. My husband took leftovers to work and a coworker asked for the recipe. Making them again tonight.

  5. I made this for the first time about 1 1/2 weeks ago and I am making them again tonight. It was a big hit with my family and they are begging for them again! 🙂

    Thank you

  6. Delicious…so tasty. I will be making this again next week. I just had to substitute oregano with Italian seasoning and thyme. Love love love it. Thank you!!

    • Hey Lisa. I super happy you loved the recipe. The seasonings are up to your taste and the one you used are some of my favorites too. Definitely a versatile recipe!

  7. Do you cook the peppers before you stuff them? and if I want to make them and freeze them for later, do I bake them and then freeze or freeze them before baked??
    Can't wait to try the recipe…sounds so good!
