One-pot Spicy Garlic Butter Parmesan Steak Pasta
Tender steak bites in a creamy, spicy garlic butter Parmesan sauce with perfectly cooked pasta. Everything made in one pot for easy cleanup.

The Art of One-Pot Pasta Perfection
The secret to successful one-pot pasta lies in the liquid-to-pasta ratio and timing. Using beef broth instead of water adds incredible depth of flavor, while the starch released from the pasta helps create a naturally creamy sauce without any flour or thickeners.
Searing the steak first creates fond (browned bits) in the bottom of the pot, which becomes the flavor foundation for the entire dish. This technique transforms a simple pasta into something restaurant-worthy with minimal effort and maximum flavor payoff.
💡 Professional Tip
Don't skip the wine deglazing step - it lifts all those flavorful browned bits from the bottom of the pot and adds acidity that balances the rich cream and cheese.
Frequently Asked Questions
Yes, ribeye, strip steak, or even flank steak work well. Cut against the grain for tenderness and adjust cooking time based on thickness. Sirloin offers the best balance of flavor and value.
Chicken broth works as a substitute, though the flavor will be milder. You can also use vegetable broth plus a beef bouillon cube for deeper flavor.
Absolutely! Reduce or omit the red pepper flakes entirely. You can always add hot sauce at the table for those who want heat.
Cook the pasta just until al dente - it will continue cooking in the hot sauce. Different pasta shapes have different cooking times, so check the package directions and test frequently.
Yes! Mushrooms, bell peppers, or cherry tomatoes work well. Add hardier vegetables with the onions, and delicate ones like spinach at the end.
Store in the refrigerator for up to 3 days. The pasta will absorb more sauce as it sits. Add a splash of broth or cream when reheating to restore creaminess.
Heavy cream is preferred for richness and stability, but you can use half-and-half. Avoid regular milk as it may curdle with the acidity from the wine and tomato paste.
Penne, rigatoni, or fusilli work best as they hold the sauce well. Avoid long pasta like spaghetti as it's harder to cook evenly in one pot and doesn't grab the sauce as effectively.
Recipe Troubleshooting Guide
Sauce Too Thin
Problem: The sauce is watery and won't thicken
Solution: Simmer uncovered for a few extra minutes to reduce liquid. The pasta starch should naturally thicken the sauce. Add more Parmesan if needed.
Overcooked Steak
Problem: Steak pieces are tough and overcooked
Solution: Cut steak into larger pieces and sear quickly over high heat. Remove promptly and only return to pot at the very end to warm through.
Pasta Sticking
Problem: Pasta is clumping together in the pot
Prevention: Stir frequently during cooking and ensure there's enough liquid. Add more broth if needed to keep pasta moving freely.
Broken Sauce
Problem: Cream sauce looks curdled or separated
Recovery: Remove from heat immediately. Whisk in cold cream or milk gradually. This often happens from too high heat or adding cheese too quickly.
Bland Flavor
Problem: Dish lacks flavor despite following recipe
Prevention: Season the steak well before searing, don't skip the fond-building step, and taste for salt at the end. Fresh garlic makes a big difference over pre-minced.
Flavor Balance Issues
Too Sweet: Add more red pepper flakes or a squeeze of lemon
Too Salty: Add cream or serve with crusty bread to balance
Bland: Increase garlic, add fresh herbs, or finish with lemon zest

Choosing the Right Steak and Pasta
Sirloin steak offers the perfect balance of tenderness, flavor, and value for this dish. Cut it into uniform bite-sized pieces against the grain to ensure every piece is tender. The steak should be at room temperature before cooking for even searing.
Penne pasta is ideal because its tubular shape holds the creamy sauce beautifully. The ridged exterior helps the garlic butter Parmesan sauce cling to each piece. Avoid overcooking - the pasta should be just al dente when you add the cream since it continues cooking in the hot sauce.
Essential Ingredient Notes
- Steak Selection: Look for well-marbled sirloin with good color. Cut into 1-inch pieces for the best texture and cooking consistency.
- Fresh Garlic: Fresh minced garlic is essential for this dish. Pre-minced garlic won't provide the same robust flavor that makes this sauce special.
- Quality Parmesan: Freshly grated Parmesan melts better and tastes superior to pre-grated. It's worth the extra effort for this rich, creamy sauce.

Mastering the One-Pot Technique
The key to one-pot pasta success is building layers of flavor sequentially. Start with searing the steak to create fond, then build the aromatic base with onions and garlic. Each step adds complexity to the final dish without requiring additional cookware.
Timing is crucial when adding the cream and cheese. The pasta should be just al dente, and the heat should be reduced to prevent the cream from breaking. Add the Parmesan gradually while stirring constantly to create a smooth, luxurious sauce.
Perfect Pasta Consistency
The pasta should absorb most of the liquid but still have enough sauce to coat each piece. If it looks too dry, add more broth. If too wet, simmer uncovered for a few more minutes.

Recipe Notes & Tips
Storage
Leftover pasta keeps in the refrigerator for up to 3 days. The pasta will absorb sauce as it sits. When reheating, add a splash of broth or cream to restore the creamy consistency.
Wine Substitution
If you prefer not to use wine, substitute with additional beef broth plus a tablespoon of lemon juice for acidity. The wine adds depth but isn't essential for the dish's success.
