Keto Stuffed Peppers Recipe

One of the biggest reasons I love these stuffed peppers without rice is its simple keto-friendly recipe but still insanely delicious. No matter how healthy a recipe is, I’m a firm believer that it should also have a ton of flavor and texture. Living the keto lifestyle doesn’t mean that food should be tasteless or boring.

Honestly, this is probably one of the most straightforward Keto recipes you’ll ever make. My son, my biggest keto food critic, said, “Mom, I think this is your best keto recipe yet.” I waited until after he finished his second helping before spilling the beans about his least favorite ingredient…..cauliflower. He hates cauliflower and can usually detect the smallest amount, but not in this recipe. 

Are Bell Peppers Keto Approved??

While you have to be mindful of the serving size, a green medium bell pepper contains only four net carbs, which makes it a healthy vegetable in moderation. All bell pepper colors have similar nutritional information.

Is Cauliflower a good vegetable to eat while on keto?

Yes, cauliflower is an excellent vegetable on the keto/low carb diet because it is versatile and low in carbs. It has tons of vitamins, minerals, and fiber. Besides the nutritional value, one cup of raw cauliflower only has three net carbs, making it the perfect keto vegetable.

Ground beef, keto taco seasoning, and cauliflower in a pan

Store-bought taco seasoning may not be the best choice due to some of the ingredients and the carb count. However, many feel that store-bought taco seasoning is okay. Check out my recipe for homemade keto taco seasoning to add to the ground beef mixture if you watch the ingredients.

Pro Tip:

In a baking dish, pop the bell peppers in the microwave for 5 minutes before adding the ground beef mixture to soften the peppers. By doing so, you heat it just enough to avoid a crispy texture when the keto-stuffed peppers are done. While these are in the microwave, it’s a good time to preheat the oven, so it will be ready when needed.

Ground beef mixture being put in bell peppers for low carb stuffed peppers

Adding salt, pepper, onions, and garlic to the riced cauliflower helps it to taste much better (just being honest here). The cauliflower rice gives the keto-stuffed peppers the texture and flavor of Mexican rice without all the carbs. My children are not huge fans of cauliflower, but they weren’t even aware it was an ingredient in this Mexican-style low-carb stuffed pepper recipe.

Cheese being sprinkled on top of the bell peppers of the keto stuffed peppers recipe

Cheese makes everything better, right? Adding cheese to Keto stuffed peppers adds fat and protein to your keto/low carb diet. You can use any cheese that you prefer. Besides white cheddar, I have also tested this recipe with Colby Jack and Monterey Jack cheese, and the dish has always turned out fantastic.

Extra Veggies in this Mexican Stuffed Peppers Recipe

Anytime I can add more veggies to a low-carb recipe and make it more healthy, I’m 100% game. I love how this low-carb stuffed peppers recipe has cauliflower as an added veggie. Feel free to play around with the amount you use, as you may enjoy more riced cauliflower. I had to play my cards carefully with this recipe as too much riced cauliflower would out my secret.

I created these Keto Stuffed Bell Peppers recipe because my family loves any Tex-Mex or Mexican food. The bell peppers, beef/riced cauliflower mixture, and taco seasoning have a rich, savory flavor. Recipes like this help us to stay on track and not get bored with our keto food choices.

What is a great filling for bell peppers?

This recipe’s Mexican ground beef mixture is a twist on traditional stuffed peppers. We loved the bold, hearty flavor the keto taco seasoning added. Although this is a Tex-Mex recipe, you could change it up and add a low-carb marinara tomato sauce such as Rao’s for more of an Italian flare.

What is good with low-carb stuffed peppers?

Adding a garden salad with an olive oil-based dressing (or your favorite alternative) to the already hearty meal will give you an easy, delicious, well-rounded keto dinner. If you want to pack an extra punch of flavor with these pepper, you can also top them in homemade keto enchilada sauce!

    This is a delicious recipe!! My husband even loves it! Also, the taco seasoning recipe is the best that I have tried. It is all I use when making any Tex-Mex recipes. Thank you so much for sharing!

  2. Make these very often! Instead of putting riced cauliflower in the ground beef mixture I make a Spanish “Rice” out of it with extra seasoning and some cheese melted right into the cauliflower. DELICIOUS!
