Ingredients
Method
- Prep the veggies: Slice the bell pepper and zucchini, shred or thinly slice the cabbage, and chop the green onions. Mince the garlic and grate the ginger.
- Make the sauce: In a small bowl, stir together soy sauce or coconut aminos, rice vinegar, sesame oil, a pinch of sweetener, and red pepper flakes or sriracha if you like heat. Set aside.
- Brown the beef: Heat a large skillet over medium-high. Add 1 tablespoon oil, then the ground beef. Break it up with a spatula and cook until browned with a few crispy bits. Season lightly with salt and pepper. Transfer to a bowl, leaving drippings in the pan.
- Sauté aromatics: Add another splash of oil if needed. Add garlic and ginger. Cook 30–45 seconds until fragrant, stirring constantly to avoid burning.
- Cook the veggies: Add bell pepper and zucchini. Stir-fry 3–4 minutes until they start to soften but still have bite. Add cabbage and cook 2–3 more minutes until just wilted.
- Combine and sauce: Return the beef to the pan. Pour in the sauce and toss to coat everything. Cook 1–2 minutes, letting the flavors meld and the sauce slightly reduce. Taste and adjust salt, pepper, and heat.
- Finish and serve: Stir in most of the green onions, saving a little for garnish. Sprinkle with sesame seeds. Serve as is, or over steamed cauliflower rice for a fuller meal.

How to Store
- Fridge: Store in an airtight container for 3–4 days.
Reheat in a skillet over medium heat with a splash of water, or microwave in short bursts.
- Freezer: Cool completely, then freeze up to 2 months. Thaw in the fridge overnight before reheating. Note: zucchini can soften after freezing, but the flavor stays great.
- Meal prep tip: Pack with cauliflower rice in a separate compartment to keep textures distinct.
Health Benefits
- Keto-friendly macros: Ground beef provides protein and fat, while low-starch veggies keep carbs in check and fiber steady.
- Micronutrient boost: Bell peppers bring vitamin C, cabbage adds vitamin K and folate, and zucchini offers potassium and hydration.
- Stable energy: The combo of protein, fat, and fiber helps curb cravings and supports steady blood sugar levels.
- Anti-inflammatory flavors: Garlic and ginger contain compounds linked to antioxidant and anti-inflammatory effects.
What Not to Do
- Don’t overcrowd the pan: Cramming in too many veggies steams them.
Use a large skillet and cook in batches if needed.
- Don’t skip the fat: A little oil helps with satiety and flavor. Ultra-lean beef can taste dry without it.
- Don’t drown it in sauce: Too much liquid waters down flavor and texture. Start with the amount listed, then add more only if needed.
- Don’t overcook the veggies: You want crisp-tender, not mushy.
Pull them off the heat while they still have snap.
- Don’t rely on sugary condiments: Many store-bought stir-fry sauces are high in sugar. Stick with soy/coconut aminos, vinegar, and spice.
Variations You Can Try
- Spicy Korean-inspired: Add gochugaru (Korean chili flakes) and a dash of fish sauce. Finish with sesame oil and sliced scallions.
- Thai twist: Swap rice vinegar for lime juice, add fresh basil or cilantro, and use a little fish sauce for depth.
- Garlic mushroom: Add sliced mushrooms with the peppers for umami richness.
Great if you want fewer peppers.
- Beef and broccoli: Replace zucchini and cabbage with small broccoli florets. Steam or sauté briefly before saucing.
- Protein swap: Ground turkey, chicken, or pork all work. Add a splash more oil for leaner meats.
- Extra-low carb: Skip bell pepper and use more cabbage, bok choy, or spinach to shave off a few carbs.
FAQ
Is soy sauce keto?
Yes, in small amounts.
Traditional soy sauce is low in carbs, but watch sodium. If you’re soy-free or prefer slightly sweeter notes, use coconut aminos.
How can I make this dairy-free and gluten-free?
It’s naturally dairy-free. For gluten-free, use tamari or coconut aminos instead of regular soy sauce, which can contain wheat.
What percentage fat ground beef is best?
Eighty-five percent lean is a sweet spot.
It gives you flavor and tenderness without being greasy. Drain excess fat if needed, but keep a little for taste.
Can I add eggs to this?
Absolutely. Scramble two eggs in the pan after the beef is browned and before adding veggies.
It adds protein and a fried-rice vibe.
What can I use instead of rice vinegar?
Apple cider vinegar or lime juice works. Start with a smaller amount and adjust to taste since acidity levels vary.
How do I keep the cauliflower rice from getting soggy?
Use high heat, a large pan, and don’t overcrowd. Cook it separately with a little oil and salt for 3–5 minutes until steam evaporates and grains are tender.
Can I make it without sweetener?
Yes.
The recipe works fine without it. A tiny amount just rounds out the savory and salty notes, but it’s optional.
How spicy is this?
It’s mild as written. Add red pepper flakes or sriracha to taste.
You control the heat level entirely.
In Conclusion
This keto ground beef stir fry proves quick dinners don’t have to be bland or complicated. With a handful of pantry staples and crisp veggies, you get big flavor, great texture, and low carbs. Keep the steps simple, the pan hot, and the sauce balanced.
