Ingredients
- 12 oz spaghetti
- 1 lb steak, such as sirloin or ribeye, thinly sliced or cut into bite-sized pieces
- Salt and black pepper, to taste
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- 2 tablespoons olive oil
- 3 tablespoons butter
- 1 medium onion, sliced
- 8 oz mushrooms, sliced
- 4 cloves garlic, minced
- 1 cup heavy cream
- 3/4 cup whole milk
- 1 1/4 cups grated Parmesan cheese
Optional
- Fresh parsley, chopped
- Crushed red pepper flakes
- Extra black pepper
Directions
1. Cook the spaghetti
Bring a large pot of salted water to a boil. Cook the spaghetti according to the package directions until al dente. Drain and set aside, reserving a little pasta water if needed.
2. Season the steak
Place the steak pieces in a bowl and season with salt, black pepper, garlic powder, and smoked paprika. Toss well so the meat is evenly coated.
3. Sear the steak
Heat the olive oil in a large skillet over medium-high heat. Add the steak in a single layer and cook for 2 to 3 minutes per side until browned. Do this in batches if needed so the steak sears instead of steams. Remove the steak from the skillet and set aside.
4. Cook the onions and mushrooms
In the same skillet, add the butter. Stir in the sliced onion and mushrooms, then cook for 5 to 7 minutes until softened and lightly golden.

5. Add the garlic
Add the minced garlic and cook for about 30 seconds, just until fragrant.
6. Make the cream sauce
Pour in the heavy cream and whole milk, stirring well. Let the mixture simmer gently for 2 to 3 minutes.
7. Add the Parmesan
Stir in the grated Parmesan cheese until melted and smooth. If the sauce becomes too thick, add a splash of reserved pasta water or a little extra milk.
8. Return the steak to the skillet
Add the cooked steak back into the sauce along with any juices from the plate. Stir gently to coat everything in the creamy sauce.
9. Toss with the spaghetti
Add the cooked spaghetti to the skillet and toss until the pasta is fully coated and everything is evenly combined.

Tips for the Best Steak Spaghetti with Mushrooms & Onions in Cream Sauce
Use a tender cut of steak like sirloin or ribeye for the best texture. Sear the steak over fairly high heat so it develops good color without overcooking. Freshly grated Parmesan melts more smoothly and gives the sauce a better flavor. If you like a little heat, a pinch of red pepper flakes works beautifully in the cream sauce.
