Why This Stir-Fry Is a Culinary Delight

What sets this Steak Stir-Fry apart is the combination of perfectly cooked steak and the rich, savory Asiago sauce. By searing the steak quickly to a rare doneness and letting it rest, you ensure it remains incredibly tender and juicy. The bell peppers and cremini mushrooms add delightful texture and earthy notes, all brought together by a simple yet decadent sauce made from pan drippings, butter, heavy cream, and sharp Asiago cheese. It’s a symphony of flavors and textures that feels indulgent but is surprisingly simple to execute.

Gather Your Fresh & Flavorful Ingredients

Here’s what you’ll need to create your impressive steak stir-fry:

• ½ medium red bell pepper, sliced
• ½ medium yellow bell pepper, sliced
• 3 ounces cremini mushrooms, sliced
• 1 tablespoon olive oil
• 8 ounces beef tenderloin fillet
• Salt and pepper, to taste
• ¼ teaspoon onion powder
• ¼ teaspoon garlic powder
• 1 teaspoon Italian seasoning
• 1 tablespoon unsalted butter
• ¼ cup heavy cream
• ¼ cup Asiago cheese, grated or shredded

Your Easy Steps to Gourmet Stir-Fry

Follow these straightforward instructions to create your delicious steak stir-fry:

1. Prepare Ingredients: Begin by gathering and prepping all your ingredients. Slice both the red and yellow bell peppers and the cremini mushrooms. Season the beef tenderloin fillet generously with salt, pepper, onion powder, garlic powder, and Italian seasoning on all sides.
2. Sear the Steak: Heat 1 tablespoon of olive oil in a large non-stick pan or skillet over medium-high heat until shimmering. Carefully add the seasoned beef tenderloin fillet to the hot pan. Sear for 2-3 minutes per side until a beautiful crust forms, keeping the steak rare in the center at this stage. Remove the steak from the pan and set it aside on a cutting board to rest.
3. Sauté Vegetables: Keep the pan on the heat, retaining any rendered fat or drippings. Add the sliced bell peppers and cremini mushrooms to the pan. Season them lightly with a pinch of salt and pepper. Sauté for about 5 minutes, stirring occasionally, until the vegetables are softened but still have a slight crispness. Remove the cooked vegetables from the pan and set them aside with the steak.
4. Slice the Steak: While the vegetables are cooking or after they’re removed, thinly slice the rested beef tenderloin fillet against the grain.
5. Make the Creamy Asiago Sauce: Return the same pan to medium-low heat. Add 1 tablespoon of butter to the pan, allowing it to melt and combine with any remaining pan drippings. Once melted, pour in the ¼ cup of heavy cream and add the ¼ cup of grated Asiago cheese. Stir continuously until the cheese is melted and the sauce is smooth and combined.
6. Combine & Heat Through: Return the sautéed bell peppers, mushrooms, and thinly sliced steak to the pan with the creamy Asiago sauce. Toss gently to coat all the ingredients in the sauce. Heat through for 2-3 minutes, stirring occasionally, just until everything is warmed through. If you prefer your steak cooked more than rare, cover the pan briefly during this step to allow it to cook to your desired doneness.
7. Serve Hot & Enjoy! Ladle the Steak Stir-Fry with Creamy Asiago Sauce into bowls or onto plates. Serve immediately and savor this gourmet meal!

Our Top Tip for Tender Steak

For truly tender, quick-cooking pieces of steak in your stir-fry, always remember to slice the steak thinly against the grain before adding it back into the pan (or even before searing, depending on your preference and cut). Slicing against the grain breaks up the muscle fibers, resulting in a more tender bite. This also ensures that each piece cooks evenly and absorbs the flavorful sauce beautifully, making for a truly delicious dish.

This Steak Stir-Fry with Creamy Asiago Sauce is proof that you don’t need a lot of time to create an elegant and incredibly flavorful meal. Enjoy every savory, creamy bite!
