For the best results, use high-quality protein like sirloin or flank steak. Slice it thin against the grain for tenderness. Most grocery stores carry pre-sliced options, but you can also ask your butcher to do it. The mixed bell peppers can be any color you like—red, green, or a mix.

No oyster sauce? Hoisin sauce can be used as a substitute, though the flavor will be slightly different. If you prefer a vegetarian version, omit the oyster sauce entirely or use a mushroom-based sauce. Fresh ginger is ideal, but ground ginger works in a pinch—start with half the amount.

This dish reheats beautifully and keeps for 3-4 days in the fridge. Freeze individual portions for up to 3 months. When reheating, add a splash of water or broth to revive the sauce. You can also prep the vegetables ahead of time and store them in airtight containers.

Step-by-Step Instructions for Mongolian Barbecue

Follow these straightforward steps to create a delicious Mongolian barbecue dish in minutes.

Step 1: Prepare the Ingredients

Start by slicing the 1 lb Sirloin Steak into thin strips against the grain. I like to partially freeze the steak for 10-15 minutes before slicing to make it easier to get even, thin cuts. Next, mince the 4 cloves Garlic Cloves and grate 2 tbsp Ginger using a microplane. Prepare the vegetables by slicing the 2 cups Mixed Bell Peppers and 1 whole Onion into thin strips, and measuring out 1 cup Snow Peas.

Having all your ingredients prepped and ready to go is crucial for stir-frying, as it happens quickly. I always keep everything within arm’s reach to maintain the cooking flow.

Step 2: Cook the Sirloin Steak

Heat 1 tablespoon Vegetable Oil in a large skillet or wok over high heat until it shimmers. Add the sliced 1 lb Sirloin Steak and cook for 3-4 minutes until browned but still slightly pink inside. I like to let it cook undisturbed for the first minute to get a good sear, then stir occasionally to cook evenly.

Remove the cooked steak from the pan and set it aside on a plate. The steak will continue to cook a bit from residual heat, so it’s okay if it’s not fully cooked at this stage.

Step 3: Stir-Fry the Vegetables

In the same pan, add the remaining 1 tablespoon Vegetable Oil if needed. Add the minced 4 cloves Garlic Cloves and grated 2 tbsp Ginger, and stir-fry for 30 seconds until fragrant. Be careful not to burn the garlic – it can go from perfect to burnt quickly.

Add the sliced 2 cups Mixed Bell Peppers and 1 whole Onion to the pan. Stir-fry for 3-4 minutes until they start to soften. Then add 1 cup Snow Peas and continue cooking for another 2 minutes until all the vegetables are tender-crisp.

Step 4: Combine and Finish with Sauce

Return the cooked 1 lb Sirloin Steak to the pan with the vegetables. Pour in 0.5 cup Soy Sauce, 2 tbsp Oyster Sauce, and 2 tbsp Hoisin Sauce. Stir everything together and cook for 1-2 minutes until the sauce has thickened slightly and coated the steak and vegetables evenly.

Remove the pan from the heat and stir in 1 tsp Sesame Oil. This adds a nutty flavor that complements the savory sauces. Taste and adjust the seasoning as needed.

Step 5: Serve and Garnish

Transfer the Mongolian barbecue mixture to a serving platter or individual plates. Sprinkle chopped 0.25 cup Green Onions and toasted 1 tbsp Sesame Seeds over the top. Serve immediately while hot, with steamed rice or noodles on the side if desired.

The dish should be vibrant with colorful vegetables and coated in a savory, slightly sweet sauce. Enjoy the combination of tender steak and crisp vegetables in every bite.

Make-Ahead Tips for This Recipe

Advance Preparation Tips

To save time on busy weeknights, I prep all the vegetables the night before. Slice the 2 cups Mixed Bell Peppers, 1 whole Onion, and measure out 1 cup Snow Peas. Store them in separate airtight containers in the refrigerator. This makes assembly quick and easy when you’re ready to cook.

Protein Preparation

Slice the 1 lb Sirloin Steak into thin strips against the grain and store it in an airtight container. You can marinate it in a mixture of 0.25 cup Soy Sauce, 1 tbsp Hoisin Sauce, and 1 tsp grated Ginger for up to 24 hours in advance. This enhances the flavor and tenderizes the meat.

Sauce Preparation

Mix the sauce ingredients (0.5 cup Soy Sauce, 2 tbsp Oyster Sauce, 2 tbsp Hoisin Sauce) in a bowl and store it in the refrigerator for up to 3 days. Give it a good stir before using as the ingredients may separate while sitting. This homemade sauce is a key component that brings everything together.

Reheating Strategy

This dish reheats beautifully, making it perfect for leftovers. To reheat, add a splash of water or broth to the mixture and stir-fry it quickly over medium-high heat. You can also microwave individual portions covered with a damp paper towel for 1-2 minutes. The sauce may thicken upon cooling, so a little extra liquid helps revive it.

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. The flavors actually meld together and improve with time. When you’re ready to serve again, a quick stir-fry or microwave reheating brings it back to life. You can also freeze individual portions for up to 3 months – just thaw overnight in the refrigerator before reheating. ❄️

Final Assembly

When you’re ready to serve, quickly stir-fry the prepped ingredients together. Add the cooked 1 lb Sirloin Steak back into the pan with the vegetables and sauce. Stir in 1 tsp Sesame Oil at the end for that authentic nutty flavor. Garnish with chopped 0.25 cup Green Onions and toasted 1 tbsp Sesame Seeds for a professional touch. Serve immediately and enjoy!
