There are nights when dinner needs to be fast, filling, and flavorful without leaving a pile of dishes behind. This Easy Keto Steak and Shrimp Stir Fry Recipe checks all three boxes.
Tender strips of beef, juicy shrimp, and colorful vegetables come together in one hot skillet with a savory sauce.
The best part is the contrast in texture. The steak gets nicely browned around the edges while the shrimp stay tender, and the vegetables keep a little bite instead of turning soft. If you are looking for a simple keto steak and shrimp stir fry for a busy weeknight, this recipe is a good one to keep handy. It also works beautifully with cauliflower rice when you want something that feels like a complete takeout-style dinner.

What Makes This Keto Steak and Shrimp Stir Fry So Good?
The secret is cooking the steak and shrimp separately before bringing everything together.
Steak needs enough heat to develop a browned exterior, while shrimp cook much faster. Putting both in the pan at the same time can leave you with overcooked shrimp before the beef is ready.
The sauce also matters. A simple combination of coconut aminos or low-sodium soy sauce, garlic, ginger, sesame oil, and a touch of lime creates a deep savory flavor without needing a sugary stir-fry sauce.
Fresh vegetables add color and crunch, so the finished skillet looks as good as it tastes.
Ingredients
For the Filling
- 1 pound sirloin steak or flank steak, thinly sliced
- 1 pound large shrimp, peeled and deveined
- 1 tablespoon avocado oil or olive oil
- 1 cup broccoli florets
- 1 small zucchini, sliced
- 1 small red bell pepper, thinly sliced
- 3 green onions, sliced
- 3 garlic cloves, minced
- 1 teaspoon fresh grated ginger
- 1 tablespoon sesame oil
Ingredient Notes
Choose a tender cut of beef and slice it against the grain. Thin slices cook quickly and are easier to chew.
For the shrimp, large or extra-large shrimp work particularly well because they remain juicy during the quick cooking process.
Coconut aminos are a good option if you prefer a slightly sweeter, soy-free sauce. Regular soy sauce works too if it fits your diet.
For the Stir-Fry Sauce
- ¼ cup coconut aminos or low-sodium soy sauce
- 1 tablespoon rice vinegar
- 1 teaspoon toasted sesame oil
- 1 teaspoon lime juice
- ½ teaspoon red pepper flakes
- ½ teaspoon garlic powder
- 1 teaspoon sesame seeds
Mix the sauce ingredients in a small bowl before you start cooking.
Why: Stir-frying moves quickly, so having the sauce ready prevents the vegetables or meat from sitting in the hot skillet too long.
Optional Add-Ins
For more variety, add sliced mushrooms, shredded cabbage, spinach, or a small amount of thinly sliced jalapeño.
If you like extra heat, increase the red pepper flakes or add a little chili garlic sauce.
For Serving
Serve the stir fry on its own for a light low-carb dinner, or spoon it over:
- Cauliflower rice
- Riced broccoli
- Shirataki noodles
- Steamed zucchini noodles
- Sautéed cabbage
If you are not following a keto diet, regular rice or noodles can also be used.
Best Sauce for Steak and Shrimp Stir Fry
A good keto steak and shrimp stir fry sauce should be savory, slightly tangy, and strong enough to coat both the beef and seafood.
For this recipe, coconut aminos, garlic, ginger, sesame oil, lime juice, and red pepper flakes create that balance. There is no need for a thick, sugary bottled sauce.
If you want a thicker sauce, mix 1 teaspoon of xanthan gum with the sauce very gradually, or simply let the sauce simmer for another minute or two.
Be careful with xanthan gum because a little goes a long way.
How to Make Easy Keto Steak and Shrimp Stir Fry
Step 1: Prepare the Steak and Sauce
Pat the steak dry with paper towels, then slice it thinly against the grain.
Season lightly with salt and black pepper.
In a small bowl, whisk together the coconut aminos, rice vinegar, sesame oil, lime juice, red pepper flakes, and garlic powder.
Keep the sauce nearby while you cook.
Step 2: Sear the Steak
Heat a large skillet or wok over medium-high heat.
Add the avocado oil, then place the steak in a single layer. Let it cook for about 2–3 minutes without moving it too much.
Turn the pieces and cook for another 1–2 minutes, depending on thickness.
Transfer the beef to a plate.
Why: Removing the steak before cooking the vegetables prevents it from becoming tough while giving the pan enough room to brown the next ingredients.
Step 3: Cook the Shrimp and Vegetables
Add the shrimp to the same skillet and cook for about 1–2 minutes per side, until they turn pink and opaque.
Remove them and set aside with the steak.
Add the broccoli, bell pepper, and zucchini to the skillet. Cook for 3–4 minutes, stirring often.
Add the garlic and ginger during the final minute.
The vegetables should be tender-crisp rather than completely soft.
Step 4: Bring Everything Together
Return the steak and shrimp to the skillet.
Pour the prepared sauce over everything and toss gently so the meat, seafood, and vegetables are coated.
Cook for another 1–2 minutes. Finish with sesame oil, sliced green onions, and sesame seeds.
Taste before adding extra salt because coconut aminos and soy sauce can already be quite salty.
Personal Observation
The nicest part of this stir fry is how quickly it changes from separate ingredients into one complete dinner. Once the sauce hits the hot skillet, the garlic and ginger become much more noticeable, and the vegetables pick up all those savory pan juices. I like keeping the broccoli slightly crisp because it gives the tender steak and shrimp some contrast. A few green onions and sesame seeds at the end make the skillet look finished without adding much extra work.
My Pro Tips & Kitchen Notes
Slice the steak thinly.
Thin pieces cook quickly and stay tender. Thick chunks can become chewy before they develop a good sear.
Dry the steak and shrimp first.
Excess moisture creates steam instead of browning. Patting them dry helps the meat develop better color.
Don’t overcrowd the skillet.
Cook in batches if your pan is small. Too many ingredients at once can lower the temperature and make everything watery.
Keep the shrimp slightly underdone before combining.
They will cook for another minute when returned to the hot skillet. This helps prevent rubbery shrimp.
Prepare the sauce before cooking.
Stir-frying happens quickly. Having everything measured and ready makes the process much smoother.
Make Ahead Tips
You can prepare the sauce, slice the steak, clean the shrimp, and chop the vegetables several hours ahead.
Keep each component refrigerated in separate containers until you are ready to cook.
For meal prep, cook the complete stir fry and divide it into individual containers. Keep cauliflower rice separate if possible so it does not absorb too much sauce.
Alternative Cooking Methods
Wok Method
A wok works especially well because the high sides make tossing the ingredients easier. Cook the steak and shrimp in small batches for the best browning.
Cast-Iron Skillet
A large cast-iron skillet gives the steak excellent browning and holds heat well.
Sheet Pan Method
For a more hands-off option, toss the steak, shrimp, and vegetables with a little oil and seasoning, then roast on a sheet pan at 425°F (220°C). Add the shrimp later in the cooking process because they need much less time than the vegetables and beef.
What to Serve With
For a complete keto dinner, try this stir fry with cauliflower rice and a simple cucumber salad.
Other good options include roasted asparagus, sautéed cabbage, steamed broccoli, or zucchini noodles.
If you want more sauce, drizzle a little of the prepared stir-fry sauce over the cauliflower rice before adding the steak and shrimp.
Storage & Freezing Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat gently in a skillet over medium-low heat. Add a small splash of water or broth if the sauce has thickened.
Microwave reheating works too, but use short intervals to avoid overcooking the shrimp.
Freezing is possible, although the shrimp and zucchini may lose some of their original texture after thawing. For the best result, freeze the cooked steak and sauce separately from delicate vegetables when possible.

Frequently Asked Questions
Can I make keto steak and shrimp stir fry with rice?
Yes. For a keto version, use cauliflower rice, broccoli rice, or another low-carb rice alternative. Regular white or brown rice can be used if you are not limiting carbohydrates.
Can I make keto steak and shrimp stir fry with noodles?
Absolutely. Shirataki noodles, zucchini noodles, or hearts-of-palm noodles are good low-carb choices.
What can I use instead of coconut aminos?
Low-sodium soy sauce is the easiest substitute. Tamari is another option, especially if you prefer a gluten-free sauce.
What steak is best for this recipe?
Sirloin, flank steak, or ribeye can all work. Sirloin is a practical choice because it is flavorful without being overly fatty, while ribeye gives a richer result.
How do I stop shrimp from becoming rubbery?
Avoid cooking shrimp for too long. They generally need only a few minutes. Remove them from the skillet as soon as they turn pink and opaque, then return them at the end for a quick finish.
Cook’s Tip
For the best texture, don’t rush the searing stage. Give the steak enough space to touch the hot skillet, and resist stirring it constantly. That little bit of patience creates browned edges and adds much more flavor to the finished Easy Keto Steak and Shrimp Stir Fry Recipe.
Conclusion
This Easy Keto Steak and Shrimp Stir Fry Recipe brings together two satisfying proteins with fresh vegetables and a simple savory sauce. It is quick enough for a weeknight but has the bold flavor you expect from a good stir fry.
The recipe is also easy to adjust. Use cauliflower rice for a complete low-carb plate, swap in zucchini noodles, or change the vegetables based on what is already in your refrigerator.
Once the ingredients are prepped, the actual cooking moves quickly. Keep the heat high, avoid overcrowding the pan, and cook the shrimp only until they are just done. That small attention to timing makes a noticeable difference in the final dish.
