What You’ll Need

• 1 pound steak (sirloin or ribeye), cut into bite-sized pieces
• 8 ounces fettuccine pasta
• 2 cups mushrooms, sliced
• 2 tablespoons olive oil
• 2 cloves garlic, minced
• 1 cup heavy cream
• 1 cup grated Parmesan cheese
• 1 teaspoon Italian seasoning
• Salt and pepper to taste
• Fresh parsley, chopped (for garnish)

Essential Tools for Success

• Large pot: For boiling the fettuccine pasta perfectly al dente.
• Skillet or frying pan: To cook the steak and roast the mushrooms with a nice sear.
• Baking dish: A medium-sized casserole dish to assemble and bake the Alfredo pasta.
• Mixing spoon: For stirring the sauce and combining ingredients evenly.
• Grater: Freshly grate your Parmesan cheese for the best flavor and melt.

The Method for Steak & Roasted Mushroom Alfredo Bake

Step 1: Prepare the pasta

Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package directions until al dente (usually about 10 minutes). Drain and set aside, reserving a little pasta water in case you need to loosen the sauce later.

Step 2: Sear the steak

While the pasta cooks, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the steak pieces generously with salt, pepper, and half of the Italian seasoning. Add the steak to the pan and sear for about 2-3 minutes per side until browned but not fully cooked through. Remove from the skillet and set aside.

Step 3: Roast the mushrooms

In the same skillet, add the remaining tablespoon of olive oil. Toss in the sliced mushrooms and cook over medium heat, stirring occasionally, for about 7-8 minutes. The mushrooms should be browned and tender. Add the minced garlic and cook for another minute until fragrant.

Step 4: Make the Alfredo sauce

Lower the heat to medium-low. Pour in the heavy cream and stir well to combine with the mushrooms and garlic. Add the grated Parmesan cheese and remaining Italian seasoning. Stir continuously until the cheese melts and the sauce thickens slightly, about 3-5 minutes. Season with salt and pepper to taste.

Step 5: Combine everything

Add the seared steak pieces back into the skillet with the sauce and mushrooms. Toss in the cooked fettuccine pasta and stir gently to coat everything evenly. If the sauce feels too thick, add a splash of reserved pasta water to loosen it up.

Step 6: Bake the pasta

Transfer the steak, mushroom, and alfredo pasta mixture into a greased baking dish. Spread it out evenly. Bake in a preheated oven at 350°F (175°C) for 15-20 minutes until the top is golden and bubbly.

Step 7: Garnish and serve

Remove the bake from the oven and let it rest for a few minutes. Sprinkle freshly chopped parsley on top for a pop of color and fresh flavor. Serve warm and enjoy!

If You’re Out Of…

• Steak: Substitute with chicken breast or thighs for a lighter version, or even a plant-based meat alternative.
• Fettuccine pasta: Penne, rigatoni, or any other sturdy pasta shape works well.
• Mushrooms: Try cremini, shiitake, or portobello for different earthy notes.
• Heavy cream: Use full-fat coconut milk or evaporated milk for a dairy-free twist.
• Parmesan cheese: Pecorino Romano or a dairy-free cheese can be used if needed.

Behind the Recipe

This Steak & Roasted Mushroom Alfredo Bake recipe was inspired by classic Italian flavors but designed to be approachable and packed with hearty ingredients that satisfy. The key is balancing the rich creaminess of the Alfredo sauce with the robust flavor of seared steak and the umami depth from roasted mushrooms. Using fresh garlic, Italian seasoning, and freshly grated Parmesan ensures every bite is full of flavor.

Baking the dish brings all the components together, melding the sauce and pasta while adding a slight crispness on top. It’s a wonderful way to serve steak and pasta in one comforting, shareable dish that feels special but is incredibly easy to make.

Save for Later: Storage Tips

• Store any leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheat gently in the microwave or in a skillet over low heat, adding a splash of cream or milk to loosen the sauce if it thickens too much.
• For longer storage, freeze the bake in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.

Helpful Q&A

Can I make this recipe dairy-free?

Absolutely! Substitute the heavy cream with full-fat coconut milk or a plant-based cream alternative, and swap the Parmesan cheese for a dairy-free cheese or nutritional yeast to keep that cheesy flavor.

What cut of steak works best?

Sirloin and ribeye are ideal because they’re tender and flavorful. You want a cut that sears well and stays juicy but isn’t too tough when cut into bite-sized pieces.

How do I prevent the steak from overcooking?

Sear the steak just until browned on each side since it will finish cooking in the oven. This helps keep it tender and juicy rather than dry and tough.

Can I prepare this dish ahead of time?

Yes! You can cook the pasta, steak, mushrooms, and sauce separately, then assemble and bake right before serving. This makes it great for entertaining or weeknight meal prep.
