1. Cook the Pasta
Bring a large pot of salted water to a boil. Cook spaghetti until al dente according to package directions. Drain, reserving ½ cup of pasta water.
2. Sear the Beef
- In a large skillet, heat olive oil and butter over medium-high heat.
- Add sliced beef, garlic, salt, pepper, and Italian seasoning.
- Cook until beef is browned but still tender (about 4–5 minutes). Remove from skillet and set aside.
3. Make the Garlic Butter Sauce
- In the same skillet, melt butter and sauté garlic until fragrant (about 1 minute).
- Stir in heavy cream and broth. Let simmer for 3–4 minutes.
- Add Parmesan cheese gradually, stirring until sauce becomes smooth and creamy.
- Season with salt, pepper, and red pepper flakes if desired.
4. Combine Pasta & Sauce
- Add drained spaghetti to the skillet with sauce. Toss to coat evenly.
- If the sauce is too thick, add a splash of the reserved pasta water until desired consistency.
5. Add the Beef
Return the seared beef to the skillet and toss with the creamy pasta. Let everything warm together for 1–2 minutes.
6. Serve & Garnish
Plate the pasta, sprinkle generously with fresh parsley and extra Parmesan, and serve immediately.
Tips for Success
- Choose the right beef: sirloin or ribeye gives the best tenderness and flavor.
- Grate your own Parmesan: pre-shredded cheese won’t melt as smoothly.
- Balance the sauce: if it feels too rich, add a squeeze of lemon juice for brightness.
- Add veggies: sautéed mushrooms, spinach, or roasted cherry tomatoes make great additions.
