Step-by-Step Instructions
Preparing the Ingredients
- Start by cooking the spaghetti. Bring a large pot of salted water to a boil, then add 12 oz of spaghetti. Cook according to package instructions until al dente, typically about 8-10 minutes. Drain and set aside.
- While the pasta is cooking, prepare your vegetables. Slice 1 medium onion and 8 oz of mushrooms, ensuring they are ready for sautéing.
- Pro Tip: Add a splash of olive oil to the boiling water before cooking pasta to enhance its flavor and prevent sticking.
Cooking the Vegetables
- In a large skillet, heat 2 tablespoon of olive oil and 3 tablespoon of unsalted butter over medium heat until melted and bubbly.
- Add the sliced onions and mushrooms to the skillet. Sauté them for about 5-7 minutes until they are softened and slightly caramelized.
- Pro Tip: Stir occasionally to ensure even cooking and prevent the vegetables from sticking to the pan.
Cooking the Steak
- While the vegetables are cooking, season 1 lb of thinly sliced steak with 1 teaspoon salt, ½ teaspoon black pepper, 1 teaspoon garlic powder, and 1 teaspoon smoked paprika.
- Add the seasoned steak to the skillet with the vegetables. Cook for about 4-5 minutes, stirring occasionally, until the steak is browned and cooked to your preference.
- Pro Tip: For a juicier steak, avoid overcrowding the skillet. Cook in batches if necessary.
Making the Sauce
- Once the steak is cooked, pour in 1 cup of heavy cream and ¾ cup of whole milk, stirring to combine everything in the skillet.
- Allow the sauce to simmer for about 3-4 minutes, letting it thicken slightly.
- Add the cooked spaghetti and 1¼ cups of grated parmesan cheese to the skillet. Toss everything together gently until the pasta is well coated with the sauce.
- Pro Tip: If the sauce is too thick, add a splash more milk to reach your desired consistency.
Final Steps
- Once everything is well combined and heated through, remove the skillet from the heat.
- Serve the Steak Spaghetti warm, garnished with chopped parsley, crushed red pepper flakes, and extra black pepper for added flavor.
- Pro Tip: For a touch of freshness, squeeze a little lemon juice over the dish just before serving.
Variations
- Swap the steak for grilled chicken or shrimp for a lighter option.
- Use gluten-free spaghetti for a gluten-free version.
- Add seasonal vegetables like spinach or zucchini for extra nutrition.
- For a spicy kick, incorporate diced jalapeños or a dash of hot sauce.
- Experiment with different cheeses, like goat cheese or feta, for unique flavors.
Serving and Storage Tips
Serving
Serve the Steak Spaghetti warm, garnished with chopped parsley for a pop of color. A sprinkle of crushed red pepper flakes adds a delightful kick, while extra black pepper enhances the flavor. Pair it with a simple green salad and a glass of red wine for a cozy dinner experience.
Storage
Store leftovers in an airtight container in the fridge for up to 3 days. For longer storage, freeze in a freezer-safe container for up to 3 months. Reheat gently in a skillet over low heat, adding a splash of milk to restore creaminess.
Common Mistakes
- Overcooking the spaghetti: Always follow the package instructions and taste for doneness a minute or two before the suggested cooking time.
- Not seasoning the steak properly: Make sure to season the steak generously to enhance its flavor.
- Using low-quality cream: Opt for heavy cream rather than low-fat alternatives for a richer sauce.
- Skipping the garnishes: Don't forget the parsley and pepper flakes; they add flavor and visual appeal to the dish.
Helpful Notes
- For a lighter sauce, consider using half-and-half instead of heavy cream.
- If you're dairy-free, substitute the cream and milk with coconut milk or a dairy-free cream alternative.
- Add spinach or kale for a boost of greens and nutrition.
- Feel free to use leftover steak for this recipe; just adjust cooking time accordingly.
