Step-by-Step Instructions
1. Season and Sear the Steak
Start by tossing steak cubes in Cajun seasoning, paprika, garlic powder, onion powder, salt, and black pepper. Heat olive oil and butter in a large skillet over medium-high heat until sizzling. Add steak in a single layer and sear each side for 2–3 minutes until browned and crusty on the outside but juicy inside. Set aside.
Pro Tip: Avoid overcrowding. Work in batches if necessary for a proper crust.
2. Boil the Pasta Shells
Cook pasta shells in salted water until al dente. Drain and set aside.
3. Make the Cheesy Garlic Sauce
In the same skillet (don’t clean it—those browned bits = flavor), melt butter and sauté garlic until fragrant. Stir in flour to create a roux, then slowly whisk in milk. Simmer 3–5 minutes until slightly thickened. Add cheddar, mozzarella, and Parmesan, stirring until smooth and creamy. Season with salt and pepper.
4. Combine and Serve
Fold pasta into the sauce until every shell is coated. Nestle steak bites back into the skillet and spoon sauce over them if desired. Garnish with fresh parsley and serve hot.
Notes and Tips
- Best Steak Cuts: Sirloin is budget-friendly and tender, but ribeye or New York strip will make this dish extra decadent.
- Spice Levels: For more heat, add a pinch of cayenne or extra Cajun seasoning. For a milder version, reduce the Cajun spices slightly.
- Cheese Swaps: Gouda, fontina, or Gruyère can add new layers of flavor.
- Make it lighter: Use half-and-half instead of whole milk, and reduce the cheese slightly.
- Extra Creaminess: Stir in a splash of heavy cream or cream cheese into the sauce.
Variations to Try
- Cajun Shrimp and Shells: Replace the steak with shrimp for a seafood twist.
- Chicken Cajun Skillet: Substitute chicken breast cubes for a leaner option.
- Vegetarian Version: Skip the steak and load the skillet with roasted veggies like mushrooms, zucchini, and bell peppers.
- Spicy Kick: Add sliced jalapeños or drizzle with hot sauce before serving.
How to Store Leftovers
- Refrigerator: Store in an airtight container for up to 3 days.
- Freezer: The cheesy pasta can be frozen (without the steak) for up to 2 months. Reheat gently on the stovetop with a splash of milk to restore creaminess.
- Reheating Steak: To keep steak tender, warm it briefly in a hot skillet or oven instead of microwaving.
Food & Drink Pairings
- Sides: A crisp green salad, garlic bread, or roasted vegetables balance the richness.
- Drinks: Pair with a bold red wine like Cabernet Sauvignon, or for a lighter option, an iced tea or citrusy sparkling water.
- Sauces: A drizzle of Cajun aioli or hot honey on top of the steak bites takes it to another level.
Frequently Asked Questions
Can I make this ahead of time?
Yes. Cook the pasta and make the cheese sauce, then store them separately. Sear the steak fresh for the best texture, and combine just before serving.
What if I don’t have Cajun seasoning?
Mix paprika, garlic powder, onion powder, cayenne, oregano, thyme, salt, and pepper for a quick homemade version.
Can I use a different pasta shape?
Absolutely! Penne, rotini, or rigatoni work well, but shells hold sauce beautifully.
How do I make this gluten-free?
Use gluten-free pasta and replace the flour in the roux with a 1:1 gluten-free flour blend or cornstarch slurry.
Can I make this in the oven?
Yes! After preparing the cheese shells, transfer everything into a baking dish, top with extra cheese, and bake at 375°F for 10–15 minutes until bubbly and golden.
