 Ingredients

• 12 oz spaghetti

• 1 lb steak (sirloin or ribeye), thinly sliced or cut into bite-sized pieces

• Salt and black pepper, to taste

• 1 tsp garlic powder

• 1 tsp smoked paprika

• 2 tbsp olive oil

• 3 tbsp butter

• 1 medium onion, sliced

• 8 oz mushrooms, sliced

• 4 cloves garlic, minced

• 1 cup heavy cream

• ¾ cup whole milk

• 1¼ cups grated parmesan cheese

Optional:

• Fresh parsley, chopped

• Crushed red pepper flakes

• Extra black pepper

 Instructions

1. Cook the pasta

   Bring a large pot of salted water to a boil and cook spaghetti until al dente. Reserve about ½ cup of pasta water, then drain and set aside.

2. Season and sear the steak

   Season steak with salt, pepper, garlic powder, and smoked paprika. Heat olive oil in a large skillet over medium-high heat. Sear the steak until browned and cooked to your liking (about 2–4 minutes). Remove and set aside.

3. Sauté onions and mushrooms

   In the same skillet, melt butter. Add sliced onions and cook until soft and caramelized (about 5–7 minutes). Add mushrooms and cook until tender and golden.

4. Add garlic

   Stir in minced garlic and cook for about 1 minute until fragrant.

5. Make the cream sauce

   Pour in heavy cream and milk. Bring to a gentle simmer, then stir in parmesan cheese. Mix until the sauce is smooth and thickened.

6. Combine everything

   Return the cooked steak to the skillet. Add the spaghetti and toss everything together until well coated. Add a splash of reserved pasta water if needed to loosen the sauce.

7. Finish and serve

   Taste and adjust seasoning. Garnish with parsley, crushed red pepper flakes, and extra black pepper if desired. Serve warm.
