Today, I’m sharing one of my favorite weeknight dinner secrets: a fusion dish that marries the robust, peppery flavors of a classic Western steakhouse with the high-heat, rapid-fire techniques of a Chinese stir-fry.
When you want the satisfaction of a good steak but don’t have the time for a full steak dinner spread, these Montreal Steak Bites with Mushrooms are the ultimate compromise. By dicing the beef, we maximize the surface area for a beautiful crust, while the mushrooms soak up all those glorious pan drippings. It’s incredibly fast, requires minimal prep, and delivers maximum flavor. Let’s get our woks smoking!
What Are Montreal Steak Bites with Mushrooms?
This dish is a brilliant East-meets-West fusion. It takes standard beef steak and button mushrooms and elevates them using Montreal Steak Seasoning—a robust blend typically featuring garlic, coriander, black pepper, dill, and rosemary. We then toss everything together in a wok with a touch of oyster sauce, bridging the gap between a classic American steakhouse and a traditional Asian stir-fry.

While today’s recipe leans into Western herbs, the traditional version relies on a rich, glossy Asian black pepper sauce and is a fantastic next step for your cooking journey!

Ingredients
- 1 Steak (approx. 1 lb / 450g): I recommend Sirloin or Ribeye for the best balance of tenderness and flavor.
- 13 White Button Mushrooms (approx. 8 oz / 225g): Cleaned and sliced. Cremini mushrooms also work beautifully.
- 1 ½ tbsp Montreal Steak Seasoning: Divided (1 tbsp for the beef, ½ tbsp for the mushrooms).
- Salt and Black Pepper: To taste (depending on how salty your steak seasoning blend is).
- 1 tbsp Oyster Sauce: The secret ingredient that bridges the flavor profile. If you aren’t familiar with it, check out our guide on Oyster Sauce Explained (How and When to Use It).
- 2 tbsp Cooking Oil: Choose an oil with a high smoke point, like avocado, canola, or peanut oil. Read our guide on the Best Oil for Stir Frying for more details.
Equipment Needed
- A well-seasoned wok or a large cast-iron skillet. Unsure which to use? Our breakdown of Carbon Steel vs Cast Iron Wok can help you decide.
- An instant-read meat thermometer (highly recommended for perfect doneness).
Prep & Mise en Place
- Dry the Meat: Using paper towels, thoroughly pat the steak dry. This is non-negotiable for a good sear.
- Dice the Beef: Cut the steak into bite-sized cubes, roughly 1-inch thick. Always remember the golden rule: learn How to Slice Meat for Stir Fry against the grain to ensure every bite is tender.
- Marinate: Toss the beef cubes with 1 tablespoon of Montreal Steak Seasoning. Let it sit at room temperature for about 10 minutes.
- Prep Veggies: Wipe the mushrooms clean with a damp cloth and slice them evenly.
Cooking Process
Step 1: Sear the Beef (2–3 minutes) Heat your wok or cast-iron skillet until it is smoking hot. Add 1 tablespoon of cooking oil. Carefully add the beef cubes in a single layer. Let them sear undisturbed for 60 to 90 seconds to build a crust, then flip.
Chef’s Secret: Patting the meat dry and using screaming high heat triggers the Maillard reaction. This chemical reaction between amino acids and reducing sugars gives browned food its distinctive flavor. Moisture is the enemy of the Maillard reaction, as it causes the meat to steam rather than sear.
Cook to your desired doneness (I aim for an internal temperature of 130°F to 135°F for medium-rare). Remove the beef from the pan and set it aside.
Step 2: Sauté the Mushrooms (3–4 minutes) Leave the residual beef fat and oil in the pan (add another tablespoon of oil if it looks dry). Add the sliced mushrooms. To understand why we cook the meat and veggies separately, take a look at our Stir Fry Order of Ingredients guide. Stir-fry until the mushrooms release their moisture and begin to brown.
Step 3: Season and Combine (1–2 minutes) Sprinkle the remaining ½ tablespoon of Montreal Steak Seasoning over the mushrooms. Add 1 tablespoon of oyster sauce and toss to coat evenly. Return the beef (and any rested juices) to the wok. Toss everything together over high heat for about 30 seconds until heated through and coated in the savory glaze. Serve immediately!
Why This Recipe Works
- Flavor Synergy: The robust herbs and garlic in the Montreal seasoning pair surprisingly well with the deep, savory umami of Chinese oyster sauce.
- Texture Contrast: High-heat searing gives the beef a slight crust while keeping the inside buttery soft, contrasting perfectly with the meaty, tender mushrooms.
- Time Efficiency: Dicing the steak cuts the cooking time down to mere minutes, making it a viable weeknight meal without sacrificing the “Sunday dinner” feel.
Common Mistakes When Making Steak Bites
- Mistake: The beef is tough and chewy.
- Cause: Slicing with the grain, or overcooking small cubes (they cook much faster than a whole steak).
- Solution: Always cut against the grain and use a meat thermometer. Remove the beef from the pan just before it reaches your ideal temp, as it will continue cooking while resting.
- Mistake: The dish turned out soggy and the meat is pale.
- Cause: Overcrowding the pan or not patting the meat dry. If you struggle with this, read Why Your Stir-Fry Turns Watery.
- Solution: Cook the beef in batches if your pan is small, and always start with a screaming hot pan and dry meat.
Frequently Asked Questions
Can I substitute the Montreal Steak Seasoning? Yes! If you don’t have it, use a heavy pinch of coarse kosher salt, freshly cracked black pepper, a little garlic powder, and a dash of dried rosemary or dill.
Can I make this ahead of time? Steak bites are best eaten fresh for the ultimate texture. However, you can slice the mushrooms and cube the beef up to 24 hours in advance to save prep time.
What kind of mushrooms work best? White button mushrooms or Cremini (baby bella) mushrooms are perfect for this. They hold their shape and act like little sponges for the beef juices.
How to Serve
These steak bites are incredibly versatile. I love serving them traditionally over a bed of fluffy white rice—learn How to Cook Jasmine Rice Perfectly to soak up the sauce. They also pair beautifully with mashed potatoes, or alongside a crisp green salad for a low-carb option.
Storage & Reheat
- Storage: Store leftovers in an airtight container in the refrigerator for 3–4 days.
- Reheat: Reheat gently in a skillet over medium-low heat with a splash of water or broth to prevent the beef from overcooking and drying out. Microwaving is not recommended as it will quickly ruin the texture of the steak.
Allergen Notice
Contains: Soy, Wheat/Gluten (Oyster sauce often contains soy and wheat extracts. Use a certified gluten-free oyster sauce if needed).
Food Safety & Nutrition Notes
Safety Tip: The USDA recommends cooking whole cuts of beef to a minimum internal temperature of 145°F (62.8°C) and allowing it to rest for 3 minutes for food safety.
