1. Cook the pasta – Al dente elbow noodles retain bite after baking.
2. Make a roux – Melt butter, whisk in flour, and create a smooth base for the sauce.
3. Blend in milk and cheese – Slowly stir until the sauce becomes silky and thick.
4. Sauté the shrimp – Lightly season, sear quickly so they stay tender, then fold them into the sauce.
5. Combine, top, and bake – Toss the noodles with the shrimp‑cheese mixture, sprinkle a crunchy breadcrumb‑cheese blend, and bake until golden.

   You’ll get a creamy, cheesy interior with a crisp, buttery crust—nothing more complicated than that.

   Unsalted butter	4 Tbsp	Can replace half with olive oil for a lighter profile.
   All‑purpose flour	3 Tbsp	Gluten‑free flour blend works the same.
   Whole milk	2 cups	Half‑and‑half or oat milk for extra richness or dairy‑free.
   Heavy cream	½ cup	Optional; reduces to 1 ½ cups milk if omitted.
   Sharp cheddar cheese, shredded	2 cups	Mix half cheddar, half Gruyère for depth.
   Parmesan cheese, grated	½ cup	Adds nutty bite; can be omitted for low‑lactose.
   Garlic, minced	2 cloves	Fresh or ½ tsp garlic powder.

   Smoked paprika	½ tsp	Optional for a gentle smoky note.
   Salt & black pepper	To taste	Adjust after tasting the sauce.

   Cooking method

6. Preheat the oven to 375 °F (190 °C). Lightly grease a 9×13‑inch baking dish.
7. Cook the pasta: Bring a large pot of salted water to a boil. Add the elbow macaroni and cook 1‑2 minutes less than package instructions (about 7 minutes). Drain and set aside.
8. Sauté the shrimp: Pat shrimp dry, season with a pinch of salt, pepper, and smoked paprika. In a large skillet over medium‑high heat, melt 1 Tbsp butter. Add the shrimp and cook 1‑2 minutes per side until just pink. Remove from heat and set aside.
9. Create the roux: In the same skillet, melt the remaining 3 Tbsp butter. Sprinkle the flour over the butter and whisk continuously for 1 minute until lightly golden—no lumps.
10. Build the sauce: Slowly pour the milk and cream into the roux while whisking. Cook, stirring, until the mixture thickens (about 4‑5 minutes). Reduce heat to low.
11. Season the sauce: Stir in the minced garlic, Dijon mustard, lemon zest, and a pinch of salt & pepper. Let the flavors meld for 30 seconds.
12. Add the cheese: Gradually fold in the shredded cheddar and half of the Parmesan, stirring until a smooth, glossy cheese sauce forms.
13. Combine everything: Toss the cooked pasta, sautéed shrimp, and cheese sauce together in a large bowl. Transfer the mixture to the prepared baking dish, spreading evenly.
14. Prepare the topping: In a small bowl, mix the panko breadcrumbs, remaining Parmesan, and a drizzle of melted butter (about 1 Tbsp). Sprinkle the blend over the casserole.
15. Bake: Place the dish in the preheated oven and bake for 20‑25 minutes, or until the topping is golden brown and the sauce bubbles at the edges.
16. Rest & garnish: Remove from oven, let stand 5 minutes. Sprinkle chopped parsley over the top, slice, and serve hot.

    Tip: If the topping browns too quickly, loosely cover the dish with foil halfway through baking.

    Tricks for success

17. Don’t overcook the shrimp – They turn rubbery fast. Cook just until pink, then finish in the oven where the residual heat finishes the job.
18. Use a double‑boiler technique for the cheese sauce if you’re nervous about scorching: keep the saucepan over simmering water and whisk continuously.
19. Season the sauce early – Add a little extra salt than you think you need; the pasta will absorb some during baking.
20. Dry the pasta well after draining; excess water thins the sauce.
21. Mix half the cheese into the sauce and reserve the rest for the topping. This gives a melty interior and a crisp, cheesy crust.
22. Add a splash of white wine to the skillet after sautéing the shrimp and let it reduce before making the roux; it adds depth without overpowering the dish.

    Recipe variations

    Variation	How to adapt
    Spicy Cajun	Toss shrimp with Cajun seasoning, add ¼ tsp cayenne to the sauce, and finish with a drizzle of hot sauce.
    Mediterranean	Substitute feta for half the cheddar, stir in chopped sun‑dried tomatoes and olives, and garnish with fresh oregano.
    Low‑carb	Use shirataki or spiralized zucchini noodles; increase the cheese ratio to keep the sauce thick.
    Vegan	Replace shrimp with smoked tofu cubes, use plant‑based butter, oat milk, and a vegan cheese blend. Add nutritional yeast for extra umami.
    Garlic‑lover	Increase minced garlic to 4 cloves, add roasted garlic puree to the sauce, and finish with garlic‑infused breadcrumbs.
    Baked‑on‑the‑rock	Swap the regular breadcrumb topping for crushed corn‑flakes mixed with melted butter for an extra‑crunchy crust.

    Feel free to experiment—each tweak creates a new favorite while preserving the heart of the casserole.

    Common questions

23. How long does the whole recipe take?
    – Prep time – 15 minutes (pasta cooking, shrimp sauté, sauce assembly).
    – Cook time – 25 minutes (baking).
    – Total – Approximately 40 minutes from start to finish.

24. Can I use frozen shrimp straight from the bag?
    – Yes, but thaw them first in the refrigerator or in a bowl of cold water. Pat them dry before seasoning; excess moisture will steam the shrimp and prevent a good sear.

25. Is this dish suitable for people with gluten intolerance?
    – Absolutely. Use a gluten‑free all‑purpose flour blend for the roux and ensure the breadcrumbs are labeled gluten‑free (or replace them with crushed gluten‑free crackers). The rest of the ingredients are naturally gluten‑free.

• Small bowl

Method

 

Preparation

1. Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

Cook the Pasta

1. Bring a large pot of salted water to a boil, then add elbow macaroni and cook for 1-2 minutes less than package instructions (about 7 minutes); drain and set aside.

Make the Cheese Sauce

1. Melt butter in a large saucepan over medium heat, add minced garlic and cook for 1 minute until fragrant, then whisk in flour and cook for 1-2 minutes to create a roux.
2. Gradually whisk in whole milk and heavy cream until smooth, then continue whisking for 5-7 minutes until the sauce thickens.
3. Reduce heat to low, stir in cheddar cheese, Parmesan, Dijon mustard, and smoked paprika until cheeses are melted and sauce is smooth, then season with salt and pepper.

Prepare the Shrimp

1. Pat thawed shrimp dry, season lightly with salt and pepper, then melt 1 tablespoon of butter in a separate pan over medium-high heat.
2. Add shrimp to the pan and cook for 2-3 minutes per side, or until pink and opaque; remove from heat.

Combine and Bake

1. Add drained macaroni and cooked shrimp to the cheese sauce, stir gently to combine, and pour the mixture into the prepared baking dish.
2. In a small bowl, combine panko breadcrumbs, remaining 1 tablespoon of melted butter, and chopped fresh parsley; sprinkle evenly over the macaroni and cheese.
3. Bake for 20-25 minutes until bubbly and golden brown, optionally broiling for the last 1-2 minutes for extra crispiness.

Garnish and Serve

1. Let the casserole rest for 5-10 minutes, then garnish with lemon zest and extra fresh parsley if desired, and serve hot.

Notes

Do not overcook the shrimp in the separate pan, as they will continue to cook slightly in the oven. For a richer flavor, use good quality sharp cheddar cheese. If you don’t have heavy cream, you can use more whole milk, but the sauce might be slightly less rich.
