What Makes This Special

Save

This stir fry is built to win three games at once: flavor, macros, and speed.

The secret is strategic veggie volume and lean beef—so you get a full bowl that doesn’t blow your calories. The sauce is umami-heavy with a little sweetness and heat, so it tastes like takeout without the mystery oils. Plus, it reheats like a champ, which is rare in the stir fry world.

And if you’re tracking, this one plays nice: predictable portions, consistent calories, zero drama.

Ingredients

• Lean ground beef or thinly sliced flank/sirloin: 1 lb (90–96% lean)
• Broccoli florets: 4 cups (about 2 medium heads)
• Red bell pepper: 1 large, sliced
• Carrots: 2 medium, julienned or thinly sliced
• Snow peas or sugar snap peas: 2 cups
• Green onions: 4 stalks, sliced (whites and greens separated)
• Garlic: 4 cloves, minced
• Fresh ginger: 1.5 tbsp, grated
• Low-sodium soy sauce: 6 tbsp
• Oyster sauce: 2 tbsp
• Rice vinegar: 1.5 tbsp
• Toasted sesame oil: 1 tsp (flavor, not frying)
• Sriracha or chili-garlic sauce: 1–2 tsp (optional heat)
• Cornstarch: 2 tsp (for light thickening)
• Water or low-sodium beef broth: 1/2 cup
• Neutral high-heat oil (avocado, canola): 1 tbsp
• Sesame seeds (optional): 1 tsp for garnish
• Lime wedges (optional): for finishing squeeze
• Optional base (to keep under 400 calories): 1/2 cup cooked cauliflower rice per serving, or 1/3 cup cooked jasmine/brown rice per serving if you’ve got extra calories to play with

The Method – Instructions

Save

1. Make the sauce. In a bowl, whisk soy sauce, oyster sauce, rice vinegar, sesame oil, sriracha (if using), cornstarch, and water/broth. Set aside. This is your glossy, low-calorie flavor bomb.
2. Prep the veggies. Slice everything into bite-size pieces.

   Keep the broccoli florets medium-small so they cook fast but stay crisp.

3. Heat the pan properly. Large nonstick skillet or wok over medium-high heat. Add half the oil and let it shimmer. Crowded pan = sad, steamed beef.

   Don’t do that.

4. Brown the beef. Add ground beef (or sliced steak). Season with a pinch of salt and pepper. Cook until browned with some crispy edges, 4–6 minutes.

   Remove to a plate. Drain excess fat if needed to keep calories tight.

5. Aromatics next. Add remaining oil. Toss in garlic, ginger, and the white parts of green onions.

   Stir 30–45 seconds until fragrant. Don’t burn—burnt garlic is a vibe killer.

6. Veggie stir fry. Add broccoli and carrots first; cook 2–3 minutes. Then add peppers and peas; cook another 2–3 minutes.

   You want tender-crisp, not mush.

7. Combine and sauce. Return beef to the pan. Give the sauce a quick stir (cornstarch settles), then pour it in. Toss for 1–2 minutes until the sauce thickens and coats everything.
8. Finish. Cut the heat.

   Add green onion tops and a squeeze of lime if using. Taste and adjust: a splash more soy for salt, vinegar for brightness, or chili for heat.

9. Portion for meal prep. Divide into 4 equal servings. If adding a base, go light to keep it under 400 calories: think 1/2 cup cauliflower rice or a small scoop of regular rice.
10. Garnish. Sprinkle sesame seeds for crunch.

    Not required, but nice.

Preservation Guide

• Fridge: Store in airtight containers for 4 days. Let it cool slightly before sealing to avoid condensation sogginess.
• Freezer: Freezes well for up to 2 months. Blanch broccoli 60 seconds before cooking if you plan to freeze to preserve texture, FYI.
• Reheat: Microwave 1.5–2 minutes, stirring halfway, or reheat in a skillet with a splash of water to re-gloss the sauce.

  Don’t nuke it to oblivion—overheating makes the veggies mushy.

• Meal prep tip: Store sauce separately if you want ultra-crisp veggies. Toss and heat right before eating.

What’s Great About This

• Under 400 calories per serving while still feeling generous thanks to high-volume veggies.
• Protein-forward from lean beef to keep you fuller, longer. No 3 p.m. snack raid.
• Ridiculously fast—weeknight or Sunday prep friendly.
• Customizable for carbs, spice level, and veggie preference without wrecking the macros.
• Reheats well, which is the Achilles’ heel of most stir fries.

  This one holds up.

What Not to Do

• Don’t overcrowd the pan. You’ll steam the beef and vegetables. Use a big pan or cook in batches.
• Don’t drown it in oil. You don’t need it. The sauce brings the gloss; the oil is just for heat transfer.
• Don’t skip the cornstarch. It’s a tiny amount but gives that takeout-style cling.

  Otherwise your sauce is sad soup.

• Don’t overcook the veggies. Limp broccoli is a morale problem. Pull them when they’re bright and crisp-tender.
• Don’t guess your portions if you care about calories. Weigh or at least eyeball evenly.

Mix It Up

• Swap the protein: Ground turkey, chicken breast, extra-firm tofu, or shrimp.

  Adjust cook times accordingly.

• Different veggies: Mushrooms, baby corn, bok choy, zucchini, green beans. Use what’s in the fridge; just keep total volume similar.
• Lower carbs: Serve over cauliflower rice or just eat it bowl-style. Add shirataki noodles for volume with minimal calories.
• Higher carbs, still reasonable: Add 1/3–1/2 cup cooked brown rice or quinoa per serving and stay near 400–450 calories depending on your macros.
• Go sweeter or spicier: A teaspoon of honey for gloss, a dash of white pepper, or chili crisp for heat (and personality).
• Citrus twist: Finish with orange zest and a splash of orange juice in the sauce for an orange-beef vibe, IMO.

FAQ

How many calories per serving is this, really?

With 1 lb lean beef, the listed veggies, and the sauce as written, each of 4 servings lands around 320–380 calories, depending on fat content and exact measurements.

Add a small base like 1/2 cup cauliflower rice and you’re still comfortably under 400. If you use regular rice, keep it to a modest scoop.

Can I make this gluten-free?

Yes. Use tamari or coconut aminos instead of soy sauce, and confirm your oyster sauce is gluten-free or swap with a gluten-free stir fry sauce.

Cornstarch is gluten-free.

Will the veggies get soggy in the fridge?

Not if you cook them to crisp-tender and cool before sealing. For best texture, reheat gently and avoid over-microwaving. If texture is critical to you, store sauce separately and combine when reheating.

Can I double the recipe?

Absolutely.

Just cook the beef and veggies in batches to maintain high heat and browning. Then combine everything with the sauce at the end.

What if I don’t have oyster sauce?

Use 1 extra tablespoon soy sauce plus 1 teaspoon honey and a few drops of fish sauce if you have it. Not identical, but it delivers that savory-sweet depth.

Is ground beef or sliced steak better?

Ground beef is faster and mixes evenly with veggies, great for meal prep.

Sliced flank or sirloin feels more “restaurant,” but requires quick high-heat searing and a watchful eye. Both work and stay under 400 when portioned correctly.

Can I make it without cornstarch?

Yes, but the sauce will be thinner. You can reduce the liquid slightly or simmer an extra minute.

Arrowroot works as a substitute; use the same amount.

In Conclusion

This Asian Beef and Veggie Stir Fry is the meal prep cheat code: fast to make, easy to scale, and friendly to your calorie budget without tasting like compromise. You get big, balanced flavor with protein that actually fills you up. It’s the kind of recipe you’ll run back weekly because it just works.

Batch it, box it, crush your weekdays—and enjoy dinner that doesn’t feel like a chore.
