- Prep Time: 15 minutes
- Cook Time: 20 minutes

This efficient timing allows you to have dinner on the table during busy weeknights while still delivering the complex flavors typically associated with slow-cooked meals. The key is proper mise en place—having all ingredients prepped before you begin cooking.

Step-by-Step Instructions
Step 1: Prepare the Beef Foundation
Season the beef strips generously with Cajun seasoning, smoked paprika, and garlic powder. Let the meat rest at room temperature for 10 minutes while you prep other ingredients. This crucial step ensures even cooking and allows the spices to penetrate the meat fibers, creating depth in every bite.
Step 2: Master the Pasta Base
Bring a large pot of salted water to a rolling boil. Add penne pasta and cook according to package directions minus 1 minute (it will finish cooking in the sauce). Reserve 1 cup of starchy pasta water before draining—this liquid gold will help bind your sauce perfectly.
Step 3: Sear the Seasoned Beef
Heat a large skillet or heavy-bottomed pan over medium-high heat. Add 2 tablespoons of butter and let it foam. Add seasoned beef strips in a single layer, avoiding overcrowding. Sear for 2-3 minutes per side until beautifully caramelized. Remove beef and set aside, keeping those flavorful drippings in the pan.
Step 4: Build the Aromatic Foundation
In the same pan with the beef drippings, add remaining butter. Sauté minced garlic and diced onion until fragrant and translucent, about 3 minutes. Add bell pepper strips and cook for another 2 minutes until slightly softened but still vibrant.
Step 5: Create the Velvety Base
Sprinkle flour over the vegetables and stir constantly for 1 minute to eliminate raw flour taste. Gradually whisk in beef broth, ensuring no lumps form. The mixture should start to thicken slightly as it comes to a gentle simmer.
Step 6: Craft the Cheese Sauce Magic
Reduce heat to low and slowly add heavy cream, stirring constantly. Add cream cheese cubes one at a time, whisking until completely melted and smooth. Gradually incorporate cheddar and Parmesan cheeses, stirring in figure-8 motions until the sauce reaches silky perfection.
Step 7: Unite All Components
Return the seared beef to the pan along with any accumulated juices. Add the slightly underdone pasta and gently toss everything together. If the sauce seems too thick, add reserved pasta water one tablespoon at a time until you achieve your desired consistency.
Step 8: Final Flavor Symphony
Let everything simmer together for 2-3 minutes, allowing the pasta to finish cooking and the flavors to meld. Taste and adjust seasoning with salt, pepper, or additional Cajun spice as needed. Remove from heat and stir in fresh parsley.

Common Mistakes to Avoid
Temperature Control Errors: 73% of home cooks overheat their cheese sauces, causing separation and graininess. Always keep heat at medium-low when incorporating dairy products, and remove from heat if the sauce starts to bubble vigorously.
Overcooking the Beef: Thin beef strips need only 2-3 minutes per side. Overcooking results in tough, chewy meat that ruins the dish’s texture contrast. Use a meat thermometer if unsure—aim for 135°F for medium-rare.
Pasta Water Mistakes: Many cooks drain pasta completely, missing the opportunity to use starchy pasta water for sauce consistency. Always reserve at least 1 cup before draining, and add it gradually to achieve the perfect coating consistency.
Seasoning Timing: Adding salt too early can draw moisture from ingredients. Season the finished dish to taste rather than heavily salting individual components during cooking.

Storing Tips for the Recipe
Refrigerator Storage: Store leftovers in airtight containers for up to 3 days. The cheese sauce may thicken significantly when cold—this is normal and easily correctable during reheating.
Reheating Best Practices:
- Add 2-3 tablespoons of milk or broth when reheating to restore creamy consistency
- Use low heat and stir frequently to prevent sauce separation
- Microwave in 30-second intervals, stirring between each interval
Make-Ahead Strategies:
- Prepare and season beef strips up to 24 hours in advance
- Cook pasta al dente and toss with a little olive oil to prevent sticking
- Grate cheeses and store separately in the refrigerator
Freezing Considerations: While possible to freeze for up to 2 months, cream-based sauces may separate upon thawing. If freezing, slightly undercook the pasta and add extra liquid when reheating.

FAQs
Q: Can I make this dish ahead of time for meal prep? A: Yes, but with modifications. Cook the components separately and combine them when reheating. The pasta and beef store well together, while the cheese sauce is best made fresh or stored separately and gently reheated with additional liquid.
Q: What’s the best way to prevent the cheese sauce from becoming grainy? A: Always use low heat when adding cheese, remove the pan from heat if it starts bubbling, and add cheese gradually while stirring constantly. Using freshly grated cheese instead of pre-shredded also helps maintain smoothness.
Q: Can I substitute the beef with other proteins? A: Absolutely! Chicken, shrimp, or even plant-based proteins work well. Adjust cooking times accordingly—shrimp needs only 2-3 minutes total, while chicken may need 6-8 minutes depending on thickness.
Q: How spicy is this dish with the Cajun seasoning? A: The heat level is moderate—flavorful but not overwhelming. Most Cajun seasonings provide warmth rather than intense heat. Start with the recommended amount and adjust to your preference.
Q: What if I don’t have heavy cream? A: Half-and-half works well, though the sauce will be slightly less rich. You can also use whole milk combined with a tablespoon of flour to help thicken the sauce.
Q: Why is my sauce too thin/thick? A: Sauce consistency depends on heat level and liquid ratios. If too thin, simmer a bit longer or add a small amount of flour mixed with cold milk. If too thick, gradually add reserved pasta water or warm broth until desired consistency is reached.
