Ingredients Method

Ingredients

  

• 1.5 pounds flank steak or sirloin, thinly sliced against the grain
• 6 cups broccoli florets (about 2 large heads)
• 1 medium onion, thinly sliced (optional but adds great flavor)
• 2 tablespoons avocado oil or light olive oil, divided
• 3 cloves garlic, minced
• 1 tablespoon fresh ginger, minced (or 1 teaspoon ground)
• 1/2 teaspoon red pepper flakes (optional)
• 1/3 cup low-sodium soy sauce (or tamari for gluten-free)
• 1/3 cup beef broth or water
• 1 tablespoon oyster sauce (or fish sauce for a deeper savoriness)
• 1 tablespoon rice vinegar
• 1–2 teaspoons honey or brown sugar (adjust to taste)
• 1 tablespoon cornstarch (or arrowroot for grain-free)
• 1 teaspoon toasted sesame oil
• 3–4 cups cooked jasmine rice, brown rice, or cauliflower rice
• Sesame seeds and sliced green onions for garnish

Method

 

1. Slice the beef: Freeze the steak for 20–30 minutes to firm it up. Slice thinly against the grain for tenderness. Pat dry with paper towels.
2. Make the sauce: In a bowl, whisk soy sauce, broth, oyster sauce, rice vinegar, honey, cornstarch, and sesame oil until smooth. Set aside.
3. Blanch the broccoli (optional but recommended): Bring a pot of salted water to a boil. Cook broccoli for 60–90 seconds until bright green and crisp-tender. Drain and rinse with cold water to stop the cooking. This helps maintain texture during reheating.
4. Heat the pan: Set a large skillet or wok over medium-high heat. Add 1 tablespoon of oil. When shimmering, add half the beef in a single layer. Sear 1–2 minutes per side until browned but not fully cooked. Transfer to a plate and repeat with the remaining beef, adding oil if needed.
5. Sauté aromatics: Reduce heat to medium. Add remaining oil, onion, garlic, ginger, and red pepper flakes. Cook 1–2 minutes until fragrant.
6. Combine and sauce: Return beef and any juices to the pan. Add broccoli. Whisk the sauce again (cornstarch settles) and pour it in. Stir and cook 2–3 minutes until glossy and slightly thickened. If too thick, splash in a bit more water or broth.
7. Taste and adjust: Add a pinch of salt or a few drops of soy if needed. For more heat, add red pepper flakes. For more acidity, add a small splash of rice vinegar.
8. Build your meal prep: Divide rice or cauliflower rice among 4–5 containers. Top with beef and broccoli. Garnish with sesame seeds and green onions.
9. Cool before sealing: Let containers cool uncovered for 15–20 minutes before closing to prevent condensation and sogginess.

Why This Recipe Works

• Balanced macros: Lean beef and broccoli deliver high protein and fiber with moderate carbs and minimal sugar.
• Quick cooking: Thin-sliced beef and a hot pan mean dinner—or a week’s lunches—comes together fast.
• Meal-prep friendly: The sauce holds well, the broccoli keeps its bite, and the flavors deepen after a day.
• Simple ingredients: Everything is easy to find, with options for gluten-free or lower-sodium swaps.
• Restaurant flavor, lighter feel: The sauce uses ginger, garlic, and a touch of sweetness without being heavy.

• Sesame seeds and sliced green onions for garnish

Instructions

1. Slice the beef: Freeze the steak for 20–30 minutes to firm it up. Slice thinly against the grain for tenderness.

   Pat dry with paper towels.

2. Make the sauce: In a bowl, whisk soy sauce, broth, oyster sauce, rice vinegar, honey, cornstarch, and sesame oil until smooth. Set aside.
3. Blanch the broccoli (optional but recommended): Bring a pot of salted water to a boil. Cook broccoli for 60–90 seconds until bright green and crisp-tender.

   Drain and rinse with cold water to stop the cooking. This helps maintain texture during reheating.

4. Heat the pan: Set a large skillet or wok over medium-high heat. Add 1 tablespoon of oil.

   When shimmering, add half the beef in a single layer. Sear 1–2 minutes per side until browned but not fully cooked. Transfer to a plate and repeat with the remaining beef, adding oil if needed.

5. Sauté aromatics: Reduce heat to medium.

   Add remaining oil, onion, garlic, ginger, and red pepper flakes. Cook 1–2 minutes until fragrant.

6. Combine and sauce: Return beef and any juices to the pan. Add broccoli.

   Whisk the sauce again (cornstarch settles) and pour it in. Stir and cook 2–3 minutes until glossy and slightly thickened. If too thick, splash in a bit more water or broth.

Storage Instructions

• Fridge: Store in airtight containers for up to 4 days.
• Freezer: Freeze portions for up to 2 months. For best texture, freeze without rice or use cauliflower rice.
• Reheat: Microwave 60–90 seconds, stir, then heat another 30–60 seconds until hot. On the stovetop, warm with a splash of water over medium heat.
• Avoid overcooking: Reheat just until hot to keep the beef tender and broccoli crisp.

Why This is Good for You

• High-quality protein: Lean beef offers complete protein to support muscle repair and satiety.
• Micronutrient-rich: Beef provides iron, zinc, and B vitamins; broccoli brings fiber, vitamin C, vitamin K, and antioxidants.
• Smart carbs: Pair with brown rice or cauliflower rice to fit your goals.

  The sauce is lightly sweetened, so there’s no sugar overload.

• Balanced meal: Protein, fiber, and healthy fats keep you full longer and stabilize energy.

Common Mistakes to Avoid

• Cutting with the grain: Always slice the beef against the grain for tenderness.
• Overcrowding the pan: Sear in batches. Crowding steams the meat and makes it tough.
• Overcooking broccoli: Aim for crisp-tender. It will soften slightly when stored and reheated.
• Skipping the cornstarch whisk: Stir the sauce right before adding it.

  Cornstarch settles and can cause lumps.

• Sealing hot food: Let the meal cool before lidding to avoid soggy rice and watery sauce.
• Using too much sweetener: Keep it minimal to highlight the savory flavors and keep macros on track.

Recipe Variations

• Lower carb: Serve with cauliflower rice, use half the honey, and skip the onion if counting carbs tightly.
• Gluten-free: Use tamari instead of soy sauce and a gluten-free oyster sauce or fish sauce.
• Extra veggies: Add mushrooms, snap peas, bell peppers, or shredded carrots. Increase sauce by 25% to coat.
• Different protein: Swap beef for chicken breast, turkey strips, or extra-firm tofu. Adjust cooking times accordingly.
• Spicy version: Add chili-garlic sauce or sambal oelek to the sauce.

  Top with sliced fresh chilies.

• Sesame-ginger boost: Double the ginger and add 1 tablespoon tahini to the sauce for a nutty twist.
• Higher protein per serving: Increase beef to 2 pounds and use 1.5x sauce; split into 5 containers.

FAQ

What cut of beef works best?

Flank steak and sirloin are reliable because they stay tender when sliced thin and cooked quickly. Skirt steak also works but can be richer. If using round steak, slice extra thin and marinate 15–20 minutes in 1 tablespoon soy plus 1 teaspoon cornstarch to help tenderness.

Can I make this without cornstarch?

Yes.

Use arrowroot or tapioca starch in the same amount, but add it at the end and avoid boiling hard to prevent a gummy texture. You can also skip thickener and reduce the sauce longer, though it won’t glaze as much.

How do I keep the beef tender?

Slice against the grain, sear in a hot pan, and avoid overcooking. A quick velvet-style marinade (1 teaspoon cornstarch + 1 teaspoon soy + 1 teaspoon oil) for 10 minutes can also help.

Is this freezer-friendly?

Yes.

Cool completely, portion into freezer-safe containers, and freeze up to 2 months. Thaw overnight in the fridge and reheat gently with a splash of water. Broccoli will be softer but still tasty.

What can I use instead of oyster sauce?

Use 1 teaspoon fish sauce or an extra tablespoon of soy sauce plus 1/2 teaspoon of molasses for depth.

For a vegetarian option, try a mushroom stir-fry sauce.

How many servings does this make?

It makes 4–5 meal prep portions, depending on how much rice you add and your appetite. If you want larger portions, scale the beef to 2 pounds and increase sauce by half.

Can I reduce sodium?

Use low-sodium soy sauce, skip added salt, and add more vinegar and aromatics for flavor. You can also dilute the sauce with extra broth.

In Conclusion

This High Protein Beef & Broccoli Meal Prep checks all the boxes: quick, delicious, and genuinely satisfying.

With lean protein, crisp veggies, and a clean, savory sauce, it’s a meal you’ll be happy to reach for all week. Customize it to your goals, keep the steps simple, and you’ll have a reliable staple that makes busy days easier and tastier.
