Are peppers okay on keto?
Bell peppers are a fantastic keto friendly vegetable to include on a low carb diet. Per 1 cup serving (150 grams) yields a mere 38 calories, 5 grams of fiber, and a mere 3 grams net carbs.
There are some who say the colors change the carb count, but they are incredibly negligible. Regardless, the bell peppers play a star role in these stuffed peppers!
These keto stuffed peppers recipe is one you’ll make on a weekly basis. Tender and juicy peppers filled with a Mexican-inspired beef and cauliflower mixture, topped with plenty of cheese. It’s the kind of dinner that comes together in minutes and something the whole family will love, keto or not.
What I love about this recipe is just how customizable they are. You can literally fill the peppers with anything and everything. Whenever I have leftover spaghetti sauce or even alfredo sauce, I love adding it to some peppers, sprinkling some cheese, and voila- Instant dinner.
How do you make keto stuffed peppers?
The Ingredients
- Bell peppers– Green, yellow, red, or a combination of the three. Try to choose equal sized ones so they all cook evenly.
- Olive oil– To sauteed the fillin.
- Onion– Finely chopped.
- Ground beef– Lean ground beef is preferred, as it keeps the overall recipe lower in fat and reduces the excess moisture that higher fat cuts of ground beef tends to have excess carbs.
- Taco seasoning– To give this dish a Mexican spin, I love adding some homemade taco seasoning.
- Canned diced tomatoes– No added salt or sugar canned tomatoes in their natural juices.
- Cauliflower rice– Steamed until tender. This not only adds extra nutrients but helps bulk out the filling without needing excess carbs.
- Cheese– Half will be mixed into the filling and half with be baked on top. I used a Mexican cheese blend but any full flavored cheese will work.
The Instructions
Start by slicing the peppers in half and removing the stems and innards. Place them in a large baking dish and set them aside. Next, prepare the filling. Add the oil into a non-stick pan and add the ground beef and onion. Cook until the beef is no longer pink. Drain excess liquid then add the taco seasoning, followed by the canned tomatoes. Let it simmer for 1-2 minutes. Remove the pan from the heat and stir through the steamed cauliflower rice, along with half the shredded cheese.
Now, distribute the filling amongst the halved peppers and sprinkle the remaining cheese on top. Place the stuffed peppers in the oven and bake for 30-35 minutes until tender and the cheese has melted.
Air fryer and instant pot instructions
Easily make this dish in the air fryer or instant pot, if you own either of them.
- Air fryer stuffed peppers– Place the prepared stuffed peppers in an air fryer basket and cook at 200C/400F for 10 minutes, turning halfway through.
- Instant pot stuffed peppers– Place the trivet into the instant pot, then add the filled peppers, minus the cheese topping. Cook on high for 10 minutes, covered. Remove the lid, add the cheese, and place the lid back on top. Let the peppers sit for five minutes, or until the cheese has melted.
Tips to make the best recipe
- Remove any excess liquid from the cauliflower rice mixture before adding it into the hollowed out peppers. This will ensure the filling remains fluffy and tender, instead of soggy.
- The larger the peppers, the easier they will be to fill. Try and find the largest ones possible, so you won’t be left with excess cauliflower fried rice.
- Do not overbake them as we want the peppers to be soft yet still tender.
Dietary swaps and flavor variations
- Make it vegetarian. Swap out the ground beef for equal amounts of chopped mushrooms, eggplant, or other vegetables.
- Make it vegan. Replace the meat with vegan ground beef (like Beyond meat) and the cheese with vegan shredded cheese.
- Switch the meat. Enjoy turkey stuffed peppers or chicken stuffed peppers by replacing the ground beef with ground turkey or ground chicken, respectively.
- Cheesesteak stuffed peppers. Fill the peppers with homemade Philly cheesesteak.
- Buffalo chicken stuffed peppers. Fill the peppers with shredded buffalo chicken.
Storing, freezing, reheating and make ahead instructions
- To store: Leftovers should be stored in the refrigerator, completely covered or in a sealed container. Some moisture will begin to form, but that can be removed when you reheat it. They will keep well for up to 5 days
- To freeze: Place cooled stuffed peppers in an airtight container and store them in the freezer for up to 6 months.
- Reheating: Microwave them for 30-40 second spurts or reheat in a preheated oven until warm.
- To make ahead: Prepare everything as instructed then cover the baking dish with aluminum foil (tin foil). Place it in the freezer for up to 1 month. When ready to cook, remove from the oven and bring it to room temperature, then cook as instructed.
What to serve with keto stuffed capsicums
This is the kind of dish that goes SO well with vegetable or low carb bread. My favorites include onion rings, keto French fries, coleslaw, cornbread, rolls, buns, and biscuits.

these look delish! I am sending this to my friend who has an abudance of peppers at the moment. hope all is well with you.
Thank you!
Tried these tonight, very good! I’ve been making them since I was hard core lazy keto. I add a little Worcestershire sauce for a beefier flavor and add a slice of provolone on top of the shredded cheese to seal them in. You could also make the recipe for half the beef, I had a lot left over! Thank you!
As always a 5-star recipe from your site! This was so incredibly delicious, even my son gobbled it down. (After kicking the pepper to the curb first. LOL) He simply grabbed a few of my 0-carb tortillas and filled three of them with one pepper’s worth of filling. I had a bit extra filling left over because I used 1.5lbs of ground Turkey, and I’m all giddy just thinking of the delicious tortillas I’ll make for lunch tomorrow. Such an incredibly versatile dish and so very tasty. Thank you!!
A new favorite recipe! I shared 1 pepper with my cousins husband and he absolutely loved it, he said he normally doesn’t even like cauliflower and loved this he was surprised. While this recipe was yummy alone I topped this with sour cream.
This says a lot because I’m kinda a picky eater😂
Thank you, Arman, for this easy recipe that tastes great! I will definitely make this on a regular basis! Your suggestions and possible variations are also very helpful.
This was super easy and delicious! I only had fajita seasoning and fire-roasted tomatoes on hand but it worked out fine. This will be my go-to recipe! I air-fried my stuffed bell peppers at350 degrees for 18 mins.
Really delicious recipe for stuffed peppers!!!
Excellent Keto recipe!! Very easy to make and honestly can’t even tell its Cauliflower rice and not white rice. I’ll be honest… I minced up 1 medium size garlic clove and added it in with the onions. Other than that, I followed the recipe!
Outstanding recipe .. next time and there will be one I would like to add some corn and black beans .. your thoughts ??
Randy
Sounds fantastic!!
Made these tonight for dinner. They were way beyond my husband and my expectations!!! Much better than the one’s I used to make before we had to go to low carb foods. I even made my own homemade cauliflower rice for the peppers. It was amazing too. The only thing I did different in this recipe… I boiled my peppers just long enough to soften them up a bit. The recipe is amazing!!!
Can I use frozen cauliflower riced or thaw first?
Thaw it first 🙂
This was a fab, super easy recipe. Defo have a new follower, whole family loves them and took no time at all, and lots of yummy leftovers for tomorrow.
I became disabled a few years back and with that pandemic/Covid crisis going on I have become somewhat housebound. My new life includes an internet addiction for news, interest articles and recipes. Somehow I stumbled across your website and I LOVE it! So many good recipes for low carb everything because, being a diabetic for over 60 years, I have to eat low carb but not that trending Keto lifestyle. I looked at a lot of your recipes and I am hooked! So many good recipes located on one website. Making the keto-stuffed green peppers tonight as my pepper plants over produced this year! Thanks for all your recipes and cooking hints!
Wishing you the very best of health, and hope you enjoy the recipes.
Second time making this. Used Quinoa instead of Cauliflower rice.
Turned out great. My son is on keto and lactose intolerant.
I used lactose free cheese. No one even know.
