When it comes to low-carb dinners, nothing beats a quick and easy meat and vegetable dish. That’s why pepper steak has been one of my long time favorites.
It’s perfect for weeknight family dinners because it cooks up in less than 30 minutes. It comes together even faster if all the ingredients have already been prepped and sliced.
That’s why I know you’re going to love this low-carb keto beef stir fry. It’s so simple you really don’t even need a recipe!
Keto Pepper Steak Ingredients
I usually make the dish with just sliced green pepper and onion stir fried with some soy sauce, broth, and seasoning. Mushrooms are completely optional.
Sometimes I’ll add in another keto friendly vegetable like broccoli or baby corn. A whole 15 ounce can of baby corn has just 10 grams of carbs, 6 of which are fiber. That’s just 4g net carbs for added to the 4 serving dish!
I’ve even made low-carb corn bread with baby corn. It’s much cheaper than having to buy the overpriced corn extract!
How To Make Low-Carb Beef Stir Fry
It only takes a few steps to make a keto stir fry with beef:
- Brown the beef with garlic in a large skillet over medium-high heat. The meat can be seasoned with salt and pepper before or after cooking. Remove from pan and keep warm.
- Stir fry the pepper and onions until tender.
- Add broth, soy sauce, and additional vegetables. Continue cooking until vegetables are crisp tender and mushrooms have softened.
- Return beef to skillet and cook until heated throughout.
That’s all there is to it!
Frequently Asked Questions
This recipe was originally published in 2010. Since that time, I’ve had a few questions so let me answer some of those here.
Red meat is a popular food on keto because it contains zero carbs. But some cooks use seasoning and rubs that aren’t carb free so you may need to look out for that.
Although I used sirloin in the recipe, flank steak is generally used for stir frying. That’s because it tends to have more flavor and does well when cut thin.
Most of the liquid should evaporate off when cooking the vegetables. But you can sprinkle in about ¼ teaspoon of xanthan gum to the broth mixture. Or, a tablespoon or so of coconut or almond flour can be mixed into the soy sauce before adding.
One medium green bell pepper has about 6g carbs and ¼ cup onion adds roughly 4g carbs. So the peppers and onions in the recipe contain about 10g total carbs which is just over 2g per serving.
Serving Suggestions
Although not needed, I like to add a bit of cauliflower rice as a side to this low-carb beef stir fry recipe. I whip it up quickly in the microwave which takes only 5 minutes.
You can also pre-shred the cauliflower and store it in single servings in the freezer. Then, when you want a serving, just pop it in the microwave or steam it up!
Adding in cauliflower rice really does complete this keto pepper steak dish. And, it reminds me of the dishes my father used to serve when I was growing up.

I added celery also Worcestershire sauce. No corn. White rice. It was excellent

This dish is fabulous! I used garlic powder instead of fresh garlic and it was perfect. I reversed the order of cooking by carmelizing my onions and peppers first (fajita-style), removed from the skillet, then cooked the steak and mushrooms. I added the onions and peppers back in at the end. For those who say their sauce is watery, adding 1/2 tsp of xantham gum AND keeping the lid off the skillet is the key to a rich, thick sauce. My husband ate 3/4 of the dish the first night, so no leftovers! I will definitely make this again and again.

I made this and it turned out a watery mess. not sauce like at all
Lisa
I typically let some of the liquid evaporate out by cooking a bit longer. Or, you can add a thickener like xanthan gum.
Sandy
Mix a tablespoon or so of coconut or almond flour in with soy sauce before you add it . This will thicken sauce. Don’t overdo flour, but if you do you can add a little water to thin it down.
Alicia
Mine didn’t come out saucy like your picture…
Lisa
The beef broth is the base for the sauce. I usually toss it to make sure the pieces get covered with the sauce.

I had a very VERY traumatic experience with sesame oil and cannot tolerate it in any quantity anymore. Even the smell of it teeters on making me feel violently ill. Is there something else that can substitute here? Is it critical to the flavor of the dish? I’ve used the “SkinnyTaste” recipe for pepper steak and loved it, and if it called for sesame oil, I’ve never included it… Is there any crossover??
Lisa
The sesame is not critical. In fact, I often use avocado oil instead.
