Let’s Talk About That Steak!
Choosing the right cut of beef is crucial for this recipe, especially if you’re aiming for a melt-in-your-mouth experience. While I recommend Filet Mignon for its tenderness and flavor, you can also use sirloin or ribeye. Just remember to trim any excess fat before cutting it into cubes. The key is to get a good sear on the steak tips to lock in the juices and create a delicious crust that complements the creamy sauce.
Spice It Up! Perfecting the Cajun Seasoning
Cajun seasoning is the heart and soul of this dish, adding that signature spicy and savory flavor. You can use a store-bought blend, but I prefer to make my own so I can control the level of heat and salt. My go-to blend includes paprika, cayenne pepper, garlic powder, onion powder, oregano, thyme, and black pepper. Don’t be afraid to adjust the amount of cayenne pepper to suit your taste buds. Remember, you can always add more spice, but you can’t take it away!Step-by-Step Instructions
Get Started:
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Cook the rigatoni according to package directions until al dente. Drain and set aside. This Pasta Dinner Recipes is about to get a major upgrade!
Prepare the Cajun Steak Tips:
- In a medium bowl, toss the filet mignon cubes with olive oil, Cajun seasoning, garlic powder, onion powder, salt, and pepper. Make sure the steak is evenly coated.
- Heat a large skillet over medium-high heat. Add the steak tips and sear on all sides until browned and cooked to your desired doneness (about 3-5 minutes for medium-rare). Remove from the skillet and set aside. Don’t overcrowd the pan; cook in batches if necessary to ensure a good sear. This is a Fast Dinner that doesn’t sacrifice flavor!
Make the Creamy Parmesan Sauce:
- In the same skillet, melt the butter over medium heat. Add the minced garlic and diced onion and sauté until softened, about 3-5 minutes.
- Whisk in the flour and cook for 1-2 minutes to create a roux. This helps thicken the sauce.
- Gradually whisk in the heavy cream and chicken broth, making sure to break up any lumps. Bring to a simmer, stirring constantly.
- Reduce the heat to low and stir in the Parmesan cheese and mozzarella cheese until melted and smooth. Season with salt and pepper to taste.
- Stir in the cooked rigatoni and Cajun steak tips into the creamy sauce. Mix well to combine.
Bake It to Perfection:
- Pour the rigatoni mixture into the prepared baking dish.
- Sprinkle the top with additional Parmesan cheese.
- Bake for 20-25 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
- Garnish with fresh parsley before serving.
Tips and Tricks for the BEST Creamy Rigatoni Bake
- Don’t Overcook the Pasta: Al dente pasta is key to preventing a mushy bake. The pasta will continue to cook in the oven, so slightly undercooking it ensures it holds its shape and texture.
- Sear, Don’t Boil: When searing the steak tips, make sure the skillet is hot enough to create a nice crust. This not only adds flavor but also helps seal in the juices.
- The Roux is Crucial: The roux (butter and flour mixture) is essential for thickening the sauce. Cook it for a minute or two to get rid of the raw flour taste.
- Freshly Grated Cheese: Always use freshly grated Parmesan cheese for the best flavor and melting quality. Pre-shredded cheese often contains cellulose, which can prevent it from melting smoothly.
- Rest Before Serving: Let the baked rigatoni rest for a few minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together.
Variations to Make It Your Own
- Add Vegetables: Sauté some bell peppers, mushrooms, or spinach and add them to the sauce for extra flavor and nutrients.
- Spice It Up Even More: Add a pinch of red pepper flakes to the sauce for an extra kick of heat.
- Cheese Lovers’ Dream: Experiment with different cheeses like Gruyere, Fontina, or Asiago for a unique flavor profile.
- Make it Lighter: You can substitute half-and-half for the heavy cream to reduce the fat content, but be aware that the sauce might not be as thick.
